Prior to discovering CreditKarma, I used to get 3 free credit reports a year using annualcreditreport.com (note: don’t fall for the catchy jingles, freecreditreport.com is a scam).  The basic idea is that each of the 3 major US credit reporting agencies is required by law to provide you with one free credit report a year, so I just made a note on my calendar to check a specific agency every 4 months.  But this doesn’t give your actual credit score, just a report of your current number of accounts and a history of bad things you may have done.  You usually have to pay some extra fee to get the score, unless you want to play a game of chicken with cancellation deadlines (which I’ve done before).  But I’m done with all that now that I’ve found CreditKarma.

CreditKarma is free and it’s pretty awesome

CreditKarma is sort of like a Mint for your credit score.  You have to enter your credentials once (name, address, social security number), and then they’ll track your score on a monthly basis (but they’ll also check it instantly at any point that you want).  It’s important to note that these aren’t “hard” credit inquiries, so they don’t hurt your score.  It’s also important to note that a lot of people are afraid of identity theft and martians and other crazy stuff, but the company seems pretty reliable to me.

Beyond quantifying your fiscal dependability in a single number, CreditKarma also provides some nice reports breaking down the individual areas that contribute to that score.  They give you a letter grade and a percentile ranking relative to the rest of the herd, helping point you in the right direction to bring that score up to par.  On top of that, you can run a “credit simulation” to predict how your credit would change based on a range of choices (paying off your loan, getting a new credit card, selling your soul, etc.).  Ok, maybe not that last one.  Anyway, all of this is pretty nice, with the only real catch being the targeted offers they show you.  Fortunately, there aren’t any annoying pop-up ads, so it doesn’t really hurt the site’s credibility much…which I guess is good for a credit scoring site.

Of course I wouldn’t necessarily expect Google to work hand-in-hand with every single third party developer, but they should at least keep some major ones in the know.  In this case I’m referring to Remember the Milk.  One of the most useful applications I’ve encountered on the web is the Remember the Milk plugin for gmail.  For those who aren’t in the know, RTM is a simple task manager that lets you easily add tasks by typing things like “Send in rent check Thursday”.  But really there isn’t anything that special about RTM when compared with the vast array of competitors (PhiTodo, Taskbarn, Remindr, teamtasks, Task2Gather, TheBigPic, Producteev, Basecamp, Planzone, and LifeTick, to name a few).  In fact, RTM really disappoints when it comes to organizing and planning big-picture goals (TheBigPic and LifeTick are both much better for this).  But the key redeeming feature for RTM is the gmail plugin.

The RTM gmail plugin is incredible.  It is one of the few utilities that I absolutely rely on to remain organized on a day-to-day basis (others include gmail and gcal).  And the key feature of the gmail plugin is that you can simply star an email and have it automatically become a task in the RTM side panel.  This is extremely helpful for keeping up with emails.  I can prioritize and postpone responses by relevance, and clicking on the task in the side panel will pull the relevant email up so I can address it right away.  These features are especially critical since probably 70% of my tasks come as emails.

Google Broke RTM

However (and this is where my beef with gmail comes in), Google frequently updates the code for gmail, and many times that actually breaks features in the RTM plugin (with over 90 instances of a break and a required RTM fix!).  It’s generally only a relatively small break for a day or so.  But for for the past three weeks (up until late Monday night), the RTM plugin has been completely down.  This is, of course, because of Google’s wide-spread updates and code freeze associated with the release of Buzz, though we had no way of knowing that when the issue first cropped up in the RTM forums.

So it’s mildly frustrating relying so heavily on a plugin that is at the mercy of every minor update pushed by Google.  I’m hopeful that Google will try to work more closely with RTM in the future.  Or maybe they could improve their own native Tasks application to bring it on par with RTM’s other features (though that’s obviously the more monopolistic solution).

</rant>

Anyway, I guess the main take-aways here are:

1. Buzz is awesome, but Google needs to play nicer with third party applications, especially as we become more reliant on these cloud services for day-to-day work.
2. You should try out the RTM Gmail plugin (make sure to use the actual Firefox or Chrome addon, the labs gadget isn’t even close).  I don’t know how I kept track of things before it.  I’ve definitely had trouble keeping up with tasks over the past three weeks while it went dark (sorry to everyone for that).

People have tried preparing budgets and tracking spending all kinds of ways, ranging from simple spreadsheets to institution-specific tools to expensive software.  There are at least three big issues with these solutions:

1. Too much effort | You really just don’t have the time to manually enter all of your purchases, and to update budgets and goals in a manual fashion over time.  At best you start off sticking to it but gradually slack off and give up.
2. Not enough metrics | These methods generally aren’t very good for organizing purchases and making sure you’re sticking with goals for specific spending categories.  This is critical for sifting through the junk to get relevant information.
3. Too isolated | These tools tend to sit in a box somewhere.  Most likely on your hard drive, though maybe in the cloud if you’re using Google Docs.  You would really want something that you could access anywhere, and that could send you relevant notifications related to your spending and upcoming bills.

This is where Mint comes in.  I’ve been using it for almost 3 years now (since they started their beta back in the summer of 2007), and I’ve been thoroughly impressed with the features and reliability they offer for tracking your finances.  All you do is input the login information you use for each of your online accounts and Mint will automatically import and categorize all of your monthly data in a clean and intuitive interface.  Here are some of the best features:

• It puts everything in one place | No more searching for specific purchases on a clunky bank website only to find you can’t actually see more than the past 6 months.  Mint keeps all of your transaction histories in one place, with simple search and auto-tagging.  It’s really amazing how comprehensive it is.  I’ve got bank accounts, credit cards, student loans, and an auto loan all in there.  If you happen to have a positive net worth, you can even track all those investments you have.
• It’s automatic | Mint is generally about 90% accurate in categorizing my transactions, making it really simple for me to get a quick look at exactly how much I spend on any particular category in a given time period (for example, how much was spent on fast food over the past year).
• It keeps you in the know | The primary concern I hear is mistrust in a startup to hold their financial information.  However, I think Mint increases your security by notifying you of anything fishy going on in your finances.  You can set all kinds of alerts based on spending and account balance thresholds, and Mint will let you know by SMS or email if anything unusual happens (still waiting for an Android app, though).
• It helps you budget | The budgeting tools help you keep track of your spending during the month, notifying you if money is disappearing faster than it should.  This has helped me scale back spending when necessary.
• It identifies trends | Mint offers some very appealing charts to help visualize your spending by category.  This way you can tighten your spending a little in areas that are hurting you most.  It also helped me identify a relatively small, but regularly recurring, withdrawal from my account that should have been canceled.  I was able to immediately contact the offending company and straighten things out.

For those of you who are concerned about leaving all your financial information in the hands of a startup, it should comfort you a little to know that they’ve been secure for the past 3 years of operation, and were even recently acquired by Intuit, a well-established financial software company.  There are tons of reasons to love Mint, and it still surprises me how many of my friends haven’t even heard of it yet.  Now you don’t have ignorance as an excuse.  Go sign up!

The Pulse

The Problem(s)

New devices don’t always have to solve existing problems, but they should at a minimum introduce you to a problem you never knew you had to begin with.  The Pulse solves several existing and new problems:

• Taking notes: It sucks when you’re jotting down notes on something but can’t quite write fast enough to keep up.  You miss some critical information and fall helplessly behind.  Problem solved.
• Actually using your notes: Ok, so you have a bunch of notebooks filled with tons of valuable information.  Now how do you access all those little bits?  Not so easy.  In an ideal world, you have everything uber-organized with a rainbow of plastic stickers.  In the real world, it’s a mess of spiral notebooks and you really aren’t going to be able to find that reference you’re looking for.  Problem solved.
• Sharing your notes: Yes, it would be nice to have all your notes in Google Docs.  But sometimes it’s just not convenient or possible to use a computer.  So then you have to resort to photocopies.  Even if you do have the notes digitized, you’re probably lacking the original audio that could prove relevant. Problem solved.
• Doing cool stuff in your notebook: This falls more into the category of problems you didn’t really know you had.  But what if you could touch a word and hear its translation into another language?  Or write a calculation and get an instant answer wherever you are on the page?  Or draw interactive elements on the page (like a piano)?  Problem preemptively solved.

How it Works

The Pulse pen fundamentally has two sensors: one to record its position on special “dot paper”, and another to record audio.  Both are incredibly sensitive and accurate, producing amazing results.  The pen uses a high speed infrared camera positioned right below the ink stick to capture images of what the ink is touching.  Livescribe has developed an incredibly large pattern of microscopic dots that are uniquely positioned so that a small look can tell you exactly where you are in the pattern.  This pattern was then cut up into pages and distributed into notebooks.  There are 4 spiral notebooks and 4 bound notebooks.  So when I take notes in Notebook 1, the pen knows exactly where I am and records all of my strokes.

Beyond just recording where I am, the pen can perform an action at a given location based on its internal map of objects drawn on the page.  The coolest example of this is definitely the piano.  It’s just something you have to see.

Docking the pen to your computer via USB will automatically transfer new notes and recordings to the Livescribe Desktop application.  The process is fairly simple and intuitive, though there were some bugs resulting from the release of the latest 2.0 software that have mostly been fixed now.  The notes are then indexed using some incredible OCR algorithms, allowing pretty reliable search, even with chicken scratch like mine.  The desktop application also interfaces directly with Livescribe Online, where you can upload “pencasts” (audio/text recordings) for public or private sharing.

The Features, The Features, What-What the Features!

Just to summarize the main features of the Pulse pen and associated software:

• Synced recording of audio and text | Enables chronological review of lectures according to your notes, and filling in any information you might not have been quick enough to jot down the first time around.
• Audio playback | In the notebook, you can touch any writing on the page and automatically play the audio that was recorded when it was being written.  Once uploaded into the software, you can do the same thing by clicking with the mouse, only now you’ll actually be able to see the text being written as the audio plays.
• Indexing and powerful search | Livescribe is able to index all of your written words with high fidelity, providing a single search box through which you can look up any notes you’ve taken in the past.  Third party apps could potentially index the audio, too.  So now all of your notes will be at your fingertips.
• Sharing and export | You can easily upload pencasts to the Livescribe website, marking them as public or just sharing them privately by email.  Your friends can then view the pencast right in their browser, or just download a pdf of the notes.  Registered users get 500MB of free space.  All notes can be exported to pdf and audio can be exported to AAC, MP4, or WAV. You can even embed the pencasts (try opening it in full-screen and clicking anywhere on the text to skip through the talk):

• Durable pen | I’ve been carrying it around in my pocket daily and still haven’t been able to break it.
• Long battery life | The battery lasts an extremely long time (I can record hours of text/audio on a single charge without getting near drained).  They officially say it can record 5 hours of text & audio, or 6+ hours of just audio & 12+ hours of just text.
• Plenty of space | The data itself doesn’t seem to take up very much room.  I only have a 1GB pen (they also have 2GB and 4GB version), but that’s been plenty for all of the notes and recordings I have made in all of my notebooks over the past year.  I’m only using about half my space so far.  And you can always “archive” your notes, removing them from the pen (but leaving them in your desktop software).
• Inexpensive media | The notebooks run ~$5 each for 200-page spiral notebooks or ~$12 each for smaller 200-page notebooks that are bound like moleskine books (they’re really nicely made for the cost).  The pens are also really affordable at just around $150.
• The App Store | Currently in beta, this is perhaps one of the most compelling features of the Livescribe platform.  The desktop software has an integrated app store through which you can download programs to your pen.  These programs can be associated with special printouts (like a balance sheet or a survey), or they can just work on their own with any piece of dot paper.  Some example applications include a language translator, a digital text converter, and a chemical structure recognition tool.  You could imagine a lot of other interesting applications that could pay off big for developers.

Cool Things to do With It

I really think the Livescribe pen is a valuable tool for almost everyone I know.  If you ever have meetings, classes, or work that requires written documentation, you should probably get one.  Here are the main cases I’ve used it for:

• Meetings | It’s great having this pen to keep track of everything that goes down at any meeting I’m in.  This makes it super easy to share what happened with people who couldn’t make it, or to give notes to people practicing a presentation (they can hear what they said, along with your feedback).  It also helps with accountability – you have an easily searchable record of what everyone said, so it certainly clarifies any later disputes.
• Talks/Classes/Conferences | I guess meetings are kind of a specific instance of this “Talks” category, with the added purpose of documenting decisions.  But the other stuff applies more generally (sharing notes with people afterwards, easily searching through them later).  And if you can’t make it to a talk, you can just loan someone your pen and ask them to take notes just like they normally would – and you magically get a set of notes synced to the entire audio of the talk.
• Work/Lab Notebook | I’ll discuss this in a bit more detail later, but I think the Livescribe platform is really awesome for lab notebooks.  I currently use a modified Livescribe notebook for all of my lab work, and it makes it incredibly easy to search for any past protocol or reagent I may have used.  It’s also really easy to share those protocols with colleagues.  And I think it’s more reliable for authentication purposes (and could be even more so if someone develops a digital signature authentication app).  On top of all that, I’ll be able to take an electronic copy of my notebook with me when I finish, so I won’t have to decide between photocopier hell and losing everything I’ve done.

The Competition

The primary competitor to Livescribe is the Adapx Capturx (pronounced “Captures”) pen.  One of the reasons it took me so long to get a Pulse is that I was waiting to see who would come out on top.  The key differences I’ve noted are:

• Livescribe has its own desktop app | Whereas Capturx integrates into Microsoft Office OneNote.  This is good and bad.  It would be nice to just integrate with an accepted standard like OneNote.  However, I’ve played around with OneNote a lot and I still don’t feel like it’s ready to be my primary notebook.  Additionally, I’ve read that the OneNote OCR does not perform as well as Livescribe’s custom algorithms.  Also, the desktop software enables a lot of other cool things, like synced audio/text playback and simple upload and sharing.
• Capturx lets you print paper with forms on it | This is pretty cool.  You can print out a spreadsheet, for example, and then write numbers in it with the pen.  Then, when you open that sheet on your computer, the numbers will automatically appear in a real excel spreadsheet (rather than just the image you would get with Livescribe).  However, this type of service is definitely in the lineup for Livescribe, and wasn’t a big enough deal to sway me.
• Livescribe has an app store | This was definitely one of the key factors in my decision.  The Livescribe pen has a lot of potential as a new platform that can be unlocked with active development.  I’m excited to see what comes out.  Though I suppose this does mean we’ll have to deal with some farting apps.

Overall, Capturx is more geared towards industrial uses and it’s not even available for direct purchase (you have to email a sales associate).  Livescribe, on the other hand, has firmly placed its bet on education.  Their pens target students for the most part, but I could see them getting picked up by others as interesting applications are developed.  Unless you run a large company and are looking to automate some data entry for a bunch of employees, you want to go with the Livescribe Pulse.

The other obvious competition will come from the onslaught of tablet computers.  I originally thought a tablet computer would be ideal for my purposes.  However, I have found it much more convenient to just use this pen and paper, particularly in situations where it would be inconvenient or impossible to use a computer.  It’s also much more informal and quick, without buggy software to deal with, making it perfect for meetings and lab work.

Room for Improvement

While I’ve been very happy with my Pulse pen (and I’ve even purchased one for my undergraduate researcher), it definitely has some issues.  The pens could be made a bit smaller and have less Jetsonian appearance.  The search component could be made a bit quicker and cleaner to navigate results.  It would also be nice for paper printing to be a bit easier.  I spent about half an hour at Staples trying to print some paper but eventually gave up (though the employee was super impressed with the pen and couldn’t believe these things were sold in Target right now).  It would also be nice to have more options for notebooks (I ended up jerry-rigging a solution for my lab notebook, which I’ll talk about more in a later post).  It would also be really cool to get some kind of video integration (like a companion camera that would sync the video with the audio and text taken by the pen).

Overall, it’s been a worthwhile purchase and I’d recommend it to any of my friends.  I gave a demo to my advisor and he immediately offered to buy one for everyone in our lab.  My parents were super impressed and are getting my sister one for her birthday (mainly to help with school).  You can also buy it most anywhere (Amazon, Target, Staples, Best Buy, Apple Stores, and direct from Livescribe).  It’s worth comparing because there are occasional discounts (10-20% off, or a free set of notebooks, worth $20).

The reason I subjected myself to this is not for some kind of comedic irony (as a known technophile, regularly comparing my Ericcson brick phone with the circle of iPhones I am generally surrounded with), but rather because I just didn’t see any phones come out during those two and a half years that were worth investing in.  And I’m not just talking about a financial investment (though that is significant as well).  There are also mental and temporal investments.  I have to learn how the phone works, get used to its strengths and flaws, and set everything up just how I want it.  On top of that, I have to invest time learning which apps are best and getting them to work properly.  And up until recently, I didn’t see any phone that was worth the money and effort for me.

The Rise of Android

My labmates seemed to think this was the most appropriate message for my birthday cake. Clearly they know me very well.

So what changed?  Google launched a mobile operating system.  This was a game-changer for me.  Before getting into why Google’s phone OS is awesome, let me just take a moment to clarify just what Android is and isn’t (you can skip this if you know more about technology than 80% of my friends apparently do):

• Android is an operating system, like Windows or OS X on computers, but designed specifically for use on small devices (such as phones or even microwaves).  It will probably be turning up on a lot more devices in the near future.
• Android is open source, meaning anyone can download the full source code and modify it for free.  This makes it attractive for hardware manufacturers as it increases their overall margins on a device.  This is comparable to what is happening with open source operating systems on computers (like Ubuntu or Google’s Chrome OS).  However, while computer operating systems have been developed for decades, advanced smart phone operating systems are still at the nascent stages of design and features offerings.  It’s thus much easier for an open source alternative to actually compete and grab market share from established systems much faster (people aren’t as committed to phone operating systems as many are to Windows, for example).
• Android is not a phone made by Motorola and sold by Verizon.  The Droid phone runs the Android operating system, but the phone itself is not made by Google.  An analogy would be a computer (phone) made by Dell (Motorola) that runs the Windows (Android) operating system.

Ok so now we’re on the same page.  But why is Android so awesome?  In my opinion, Android kicks ass because:

1. It’s open | This has a few advantages.  First, it’s free (ultimately reducing the bottom line on phones).  But beyond that, it is able to grow with fairly rapid development cycles.  Additionally, third party software is not regulated like it is on some fascist phones, leading to more creative and compelling applications.  Shady policies surrounding software moderation are even driving developers to quit the iPhone.
2. It unifies my phone-to-phone experience | It used to be that the only thing you cared about carrying over from one phone to the next was your contacts (and even this wasn’t a given – hence the many requests you see from people who have suddenly lost their address books).  But now you’d like to switch to a new phone and be able to easily port your contacts, photos, text messages, applications, and other settings.  If you lock yourself into a walled operating system and at some point you want to move to a cooler phone with a different OS, you’re basically out of luck.  But since Android is being implemented on tons of phones now, from every carrier, you can readily jump from handset to handset while preserving your basic user experience and data.  Google even plans to integrate a settings backup/restore feature to be implemented in the near future.
3. It’s backed by Google | And Google is awesome.  They encourage optimal user experience in an array of applications.  Almost every important application I use these days is improved by Google’s forward-thinking designs.  And although some people are concerned about Google owning too much of our digital lives, I personally believe Google doesn’t intend to do any evil, and they’ve made some good strides for openness and data portability.  Google is definitely in a strong position to revolutionize the mobile phone industry.
4. It is well-designed | Sure, some of it is just eye candy, but the Android interfaces are really aesthetically pleasing and generally intuitive to manipulate.  It also facilitates an unprecedented amount of customization of user experience.  It’s an efficient and enjoyable OS to interact with.

The Perfect Storm

Yet, even with all of the clear benefits of moving towards an Android operating system, I passed on the earlier iterations of the G1 and MyTouch.  It wasn’t until the HTC Hero launched that I was finally ready to make my investment.

The launch of the Hero was regarded by many as the first real competition for the iPhone in terms of performance and functionality.  While previous Android phones were still a bit buggy and suffered from issues with battery life, speed, and basic functionality as a phone, HTC really built an excellent phone here.  This phone also marked the introduction of HTC’s Sense UI, which is basically a modification of the Android OS to improve the user experience with some additional customization options.  All in all, the hardware was finally there.

On top of this, I was surprised to find how appealing the actual carrier was in this instance.  The Hero was the first Android phone launched on the Sprint network in the US.  I had always used AT&T as my carrier (except for the brief period when it became Cingular and then eventually reverted back).  And Sprint was actually really cheap!  From some basic searching online, I discovered Sprint will give a discount to pretty much anyone with an organization email address.  You just enter your email address at this site and they’ll send you a link to your “Private Sprint Store”.  The specific rates vary, but for Berkeley this amounted to a 20% discount on plans!  So this made the $69.99 unlimited plan (unlimited calls to any phone, unlimited data, and unlimited texts) just $56/month (about half what it would cost to get a similar plan with AT&T or Verizon).  On top of that, I’ve anecdotally found the Sprint network to be really dependable in the areas where I’ve used it (Berkeley, San Francisco, Boston, Maryland, DC), and I seem to get better coverage than I used to with AT&T.  So this helped push me over the edge with the Hero.

The Downside

So it’s about time I get to the title of this post.  There are a few issues I’ve run into with this phone, but perhaps the most significant one is that of OS branching.  Basically, since Android is open source, third parties can modify the core code that Google originally wrote to add specific functionality.  This is like particular distributions of Linux that are modified to function/look a certain way (such as Ubuntu).  In fact, Android itself is a particular distribution of the Linux kernel.  So in the case of the Hero, HTC has modified the core Android code to implement it’s “Sense” UI.  This has likely improved the user experience, though I haven’t played with other android phones (but I have friends using the Motorola Droid who seem to like my phone better specifically because of this UI enhancement).  The downside is that now I have a very special version of Android that has to be specially modified any time there are core upgrades to the Android OS (which have been coming rather frequently with the a new version seemingly released with each new phone).

When I got the Hero, the most up-to-date version of Android was 1.5 (also known as Cupcake, in Google’s line of dessert-inspired names).  It was very quickly upgraded to 1.6 (Donut), but I wasn’t able to make this upgrade on my phone because of the modifications HTC made to the OS (without rooting my phone, voiding warranties, etc.).  Sprint announced an upcoming upgrade to 1.6, but then the Droid came out with 2.0 and the timeline for release has gradually moved back to the point where Spring has now said we’ll skip 1.6 and jump straight to 2.1, sometime in the first half of 2010.  That could be June.  And by then, 2.5 or 3.0 might be released.  So the upgrade cycle definitely lags thanks to OS branching.

Hopefully these sorts of delays will be reduced by adjustments to the core Android platform in the future (and as more phones offer the “full” Google experience), but for now you just have to be satisfied with the phone as it is when you buy it, knowing its OS could be obsolete in a matter of weeks.  And I’m definitely satisfied with my Hero, so Android limbo isn’t so bad afterall.

The sad part came when I realized I had forgotten a significant amount of the material I had mastered only a couple of years earlier.  Moreover, I was finding the material even harder the second time around.  This made me come to two harsh realizations:

1. My high school instruction was better than the equivalent MIT instruction for this particular course.
2. I can forget something pretty quickly, particularly if I’m not using it regularly.

This really marked a turning point in my education.  For the first time, I felt the frustration of viewing previously familiar material with virgin eyes.  Realizing how short-lived any particular piece of knowledge could be, I decided I would no longer sweat the small stuff.  I didn’t kill myself memorizing and practicing things that I didn’t find interesting or relevant for my near-term future.  I grabbed the big picture, and delved in deeper just where I felt like it.  As a result, MIT was a very pleasant experience for me.  Unlike my indiscriminately intense study habits in high school, I decided to focus on just the parts I cared about, knowing that I’d have to relearn anything that I needed to actually use in the real world.

This obviously is not efficient.  Both the impersonal method of instruction, and the (effectively nonexistent) means of knowledge retention in the current system leave quite a bit to be desired.  So what will education look like in the future?

Education will be Personal

This is what we were all told in third grade while taking those silly tests to determine our learning style.  I probably leaned more towards the visual/reading side of things, and secretly questioned the validity of “kinesthetic” learning, but it didn’t really matter anyway.  These tests never had a real impact on anyone’s academic pursuits.  Education is still done one batch at a time, with everyone receiving the same content.  At best, some instructors mix teaching styles with some overlap in order to bring as many students along as possible (link), perhaps incorporating hands-on experiments, group discussions, and visual effects into a standard lecture.  But this isn’t the ideal solution.  When I say personal, I mean really personal.

Every student brings two wild cards to the education table: their learning style, and their current knowledge.  Now those are some pretty huge frickin’ variables, and I’d argue the latter is most important.  Yet, students are all presented with the exact same material within a given batch, at best receiving some sort of “refresher” or “catch-up” material.  This can’t possibly fill all of the cracks.  So you end up with a good percentage of students trying to learn new material on a foundations that is full of gaps.  Not the best structural engineering approach.  Especially considering you can’t really teach someone anything unless they almost already know it (forgot who said this – anyone know?).

Learning is incremental and it’s nearly impossible to really grasp new material before fully understanding the concepts preceding it.  This is partially why I much prefer to read a whole textbook from cover to cover rather than receive whatever bits and pieces my teacher chooses are important enough to cram into an artificially-imposed academic calendar.  Courses need to be personal not just to the student, but also to the material.  Students should accomplish work at their own pace, with recommended windows for milestone completion to help motivate them along.  The key is to always be progressing and retaining what you are learning, not necessarily to move faster than everyone else.  Regular assessment of understanding would be integral, allowing students to review any modular subjects they might be lacking.

As an intermediate step, video lectures will become much more popular, and we’ll eventually see the “best” Physics 1 lectures rise to the top.  This is already happening, with recent studies showing that 82% of students at University of Wisconsin-Madison would rather watch video lectures, with 60% saying they would even be willing to pay for those lectures.  Their reasons generally were linked to a more personal experience (watching lectures “on-demand”, making up for missed lectures, etc.)  But eventually, the standard lecture format will have to give way to more interactive media that tests and reinforces throughout the teaching process.

Interactive Learning will Take Over

While working at Lawrence Livermore National Labs, I took a few online training courses that involved interactive material.  The interfaces definitely weren’t ideal, but they were a step in the right direction.  Users were presented with flash-based tutorials followed by simple quizzes to reinforce key topics, with some navigation controls to help with reviewing material that was not adequately retained.

Imagine how much further this could be pushed.  You could open up a video of a lecturer speaking, with interactive tutorial elements playing on the side.  These could be standard graphs, figures, and videos, or more complex boxes taking in user inputs to produce simple visualizations that explain a concept much better than the waving of a hand or the scratching of chalk.  MIT has some of this kind of content associated with their courses, but it’s definitely not as well-integrated into individual curricula as it should be.  It’s fairly clunky to have to go back and search through a list of visualizations when you’re first learning (or subsequently reviewing) a topic.

So now you have a student immersed in an interactive lesson, maybe even taking advantage of some new Minority Report-style interface tools being developed by a few companies.  Throughout the process, students can be prompted with questions to confirm they are grasping a concept before moving onto the next one.  In large lectures, this doesn’t happen.  If you get lost somewhere, you remain in the dark for the rest of your miserable time there.  You could ask a question, but that’s a fairly inefficient solution in a large room of students where many people are not lost.  But with gradual questions integrated throughout the process, it’s easy to identify any stumbling points.  The software could even be smart enough to break a question down into component concepts, asking a second series of questions, and a third, and a fourth, and so on, until the root problem area is identified.  The student can then review that area until he or she is ready to return to the work at hand.  That’s real no child left behind.

Obviously there are some subjects that are more readily amenable to this new education platform.  Mathematics, language, and the sciences are all excellent candidates.  Some components of humanities education could also be addressed, with some modification.  Writing might use peer-based editing and assessment (much like many writer groups that are being formed online today).  Artistic and physical instruction can also be addressed with a range of new input devices.  The Wii is great for a lot of things, and there’s finally an educational game for guitar hero with an actual guitar.  These kinds of devices could eventually be integrated into a complete, interactive learning environment that is much more personalized than anything that could be offered in batch classroom settings.

Optimized Review will be Critical

A number of studies have emphasized the value of spaced repetition for memory retention.  The basic idea is that, after you’ve learned something it is very easy to remember upon review the next day.  Then, as time goes on, it becomes harder and harder to remember until you have no clue what it was anymore.  It turns out it’s probably optimal to review this material right before you’re about to forget it.  With spaced repetition, you review the concept at optimally-designed intervals to make sure you never forget the concept, with minimal time expenditure.  A number of companies have been developing software to help push spaced repetition, but it has mostly been limited to desktop applications with flashcard-style learning (great for language, but sub-optimal for most other things).  Smart.fm has received quite a bit of press lately for applying these strategies in a simple, web-based platform.

The successful integration of optimized review right into the learning process will have a huge impact on education, helping students to actually remember most of what they’ve been taught, and saving all of the wasted time catching everyone up at the beginning of every new semester.

It will be Cheap and Ubiquitous

Right now I’ve got a phone in my pocket that is more powerful than the average computer was a few years ago.  And on that phone I have access to millions of bits of absolutely free information, anytime and (almost) anywhere.

Of course many people rely on Wikipedia as the trusted source for a first go, but expert-produced content is making its way into the free space.  There are a number of sources for free video lectures, including my personal favorite.  An MIT alumnus has even started a Youtube channel that offers comprehensive instructional videos on everything from chemistry to differential equations to banking (1000+ videos!, thanks for pointing it out, Jamie).  And recently, open source textbooks have gained some momentum with Flat World Knowledge and Wikibooks.  Our very own Governator even pushed an initiative this year to get open source textbooks in high school classrooms throughout California, with the hope of ensuring high-quality and affordable education for everyone.

Ultimately, I believe educational content will become extremely cheap or free.  But I don’t just mean video lectures and textbooks.  I’m talking about entire educational programs with web-based content that’s optimized to improve students’ learning.  Initial investments developing these programs will pay off as they drastically reduce many other economic burdens imposed by the traditional education industry.

And being web-based, these tools will be available to everyone with an internet connection, a number that is continuing to grow.  Phones could even be used for rapid review of appropriate content.  You could run through some vocab or quick math problems while waiting in line.  And it could even become addictive if presented in a game format.  The popularity of educational games on devices such as the Nintendo DS demonstrates that people are both willing and eager to apply their brains to constructive problems in gaming environments.  So education will be cheap, everywhere, and addictive.

But Classrooms Still Have a Place

Moving to an entirely digital education would obviously have some terrible repercussions for social development.  From the beginning of my time at MIT, I realized the reason the place was special wasn’t because of any fancy machines or brilliant lectures.  It was special because of the connections you could make with some really amazing people.  They used to say that at MIT there are three things that take up your time: Sleep, Social, and Study.  You can only choose two.  Anyone in my freshman dorm can tell you that Social ranked pretty highly for me, with Sleep taking a bit of  a back seat.

Although some peer discussion could take place online, students will need actual human interaction to prepare them for the inherently collaborative nature of modern working environments.  That’s why these tools would largely have to be an enabling supplement for higher-level discussions and projects in a classroom setting.  Students could complete 80% of the learning on their own, with teachers and parents monitoring their progress via web interfaces.  Then they could go to class knowing they have something substantial to contribute to bigger, more integrative goals.

So when do I get my robo teacher?

I’ve primarily been discussing ideal education systems for the future, but what’s practical in my lifetime?  The biggest issues may lie in the fact that education is a huge industry.  And like any huge industry, it has a lot of inertia that will take time to adjust.  AcademHack has a great video presenting the issues our outdated “knowledge creation and dissemination” system will face in a modern, connected world.  There are going to be some tough growing pains, much like we’ve seen with the recording industry, the film industry, television networks, and publishers.  But clearly a lot of changes have to be made to reach an optimal system.

These tools will likely be implemented on a more individual basis in the near-future, as supplements to traditional schooling.  However, it’s clear that our nation is moving towards efficiency by technology and personalization.  We’ve been trying to get away from batchucation (coining a term – education in batches), and we finally have the web-based tools to make it happen.  I’m excited to start using some of them to finally refresh all of the material I’ve inevitably forgotten.

As some of you are aware, I will be temporarily disconnected from the intertubes for the next couple of weeks while floating around the Peruvian Amazon teaching kids about healthcare, electronics, and the environment. The main idea is to provide some practical resources and training to children in remote settings, with the goal of inspiring the next generation of technological community leaders.  The initiative, called Future Scientist, will hopefully expand to other locations with the goal of developing a sustainable remote education platform.

This is a bit of an experiment a few of us here at Berkeley are putting together, so we are expecting more than a few hurdles in the beginning.  However, I believe we’ll be able to make some kind of an impact within the communities we reach, and we’ll ideally bring back some ideas about education and volunteering in general through constant and thorough needs assessment.

This trip will be a little reminiscent of my time in the Dominican Republic providing medical outreach to impoverished communities.  However, there is the striking difference that this trip is grounded primarily in science and education, whereas the DR program was centered around community service through Christian missionary activities.  In fact, the majority of this kind of aid tends to be supported (and financed) by religious institutions.  So it will be interesting trying out some work under a secular model of sustainability.

In other news, I have finally launched my modeling career, starting with my painfully photogenic hands:

Next up is an interview with SugarSync (more on that later).

Science is riddled with failure

Really, it’s all over the place.  It’s built right into the scientific method.  You make a hypothesis, with a firm understanding that anything could happen to disprove your faulty notions.  Sometimes it works and you see what you expected, and sometimes it doesn’t.  And some of the most interesting discoveries of all time have come from these “accidents” where researchers stumbled on something that didn’t work how they expected it to.

However.  The majority of these scientific snafus result in absolutely nothing.  You just blew 16 hours and $3,000.  Gone.  But at least now you know that mixing A & B only produces C when you have the conditions very precisely set at D.  But what happens to all of your failed attempts?  Your (very expensive) failed attempts?

They disappear.  There is neither forum nor incentive for researchers to publish their failures.  This leads to an enormous amount of redundant effort, burning through millions of dollars every year (many of which are funded by the tax-payer).  The system sounds really inefficient, right?  So why do we do it?

People tend to focus on successes.  Sure, things didn’t work out 6 or 7 or 17 times…but then one time it all came together.  And then you go back and repeat every single obscure condition that led to your ephemeral success (even wearing the same underwear and eating the same breakfast – but maybe I’m just more scientifically rigorous than most).  And what do you do?  You manage to repeat the success and you publish it.  Maybe you publish a parametric analysis showing how you optimized your result.  But you have left a multitude of errors and false starts in your wake that will never see the light of day, leaving countless other researchers to stumble into the very same unfortunate pitfalls.  It’s a real waste.

But this protects you.  In the business world they call it “barriers to entry“.  You’ve managed to find yourself racing ahead in first place on something and the only thing you can do to protect yourself is drop banana peals to trip up your competitors (fingers crossed nobody gets a blue turtle shell).  On top of that, every time you publish something, you’re putting your reputation on the line.  A retraction can be devastating, particularly for an early career.  Why take such a risk just to publish something that doesn’t even seem very significant?  It doesn’t help you any.  But is this good for science?  Of course not.  You’re delaying progress.  You’re wasting money.  And, particularly in the medical sciences, you’re probably actually killing people.

So Let’s Document The Traps

I propose a journal devoted entirely to failures.  Scientists can publish any negative results that are deemed “unworthy” of standard publication.  Heck, we can even delay publication by 6-12 months, to give the authors a little head-start on their competitors.  And there would have to be some sort of attribution.  But nobody wants their name attached to The Journal of FAIL.  So let’s call it The Scientific Journal of “Progress”.  Maybe without the quotes.

I wasn’t sure if such a journal existed already (though if it does, I certainly haven’t heard of it – and I’d probably be one of the biggest contributors, right behind this guy).  The only close option that came up was the Journal of Failure Analysis and Prevention, but they seem to be focused on mechanical/chemical failures in industrial settings.  So the playing field is still wide open.

Imagine if every experimental loose end was captured, categorized, and tagged in an efficient manner so that any person following a similar path in the future could actually have a legitimate shot at learning something from the mistakes of others.  It would be kind of like a Nature Methods protocol, but actually including all of the ways things can go wrong.  Authors could even establish credibility by describing why certain conditions didn’t work (a very uncommon practice among scientists).  We might have to develop some technological tools that automatically pull and classify data as researchers collect it, making it a simple “tag and publish” task for the researcher.  And people could reference your findings in the future, providing you with even more valuable street cred for the entire body of work you have developed (not just the sparse successes).

Of course none of this will happen any time soon.  There simply isn’t enough of a motivating force to drive this kind of effort (besides good will).  Maybe one day science will get its collective head out of its collective ass and things will change.  And this will be one of those things.  In the meantime, I will do my best to record and post tips on avoiding my own scientific missteps.

BONUS WEB2.0 TOOL: TinEye

[you've read this far, you deserve a reward]

I originally did a google search for “Science Fail” and found the first image of this post on another blog.  I was curious about the actual origins of the image, so I used the TinEye image search engine to find the real source.  Tineye is just like any other search engine, except your query is an actual image.  You just upload (or link to) an image of interest, and TinEye scours the web for any similar images (actual pixels, not metadata).  I quickly found that the picture originally camed from a “Science as Art” competition sponsored by the Materials Research Society (MRS).  TinEye searched over 1.1011 billion images in 0.859 seconds to find that result.  Pretty nifty, right?

The obvious applications are for controlling the distribution of copyrighted images, and there are some potentially frightening applications of such technology for facial recognition in the not-so-distant future (imagine someone sees you on the street, snaps a picture surreptitiously, and does a quick image search to find out who you are – and they’re likely to find out everything).  Scary.  But still kind of fun.

Rick's Brain on Science

Admit it.  You like science.  You thrive on the unknown.  You seek adventure and mystery.  You enjoy being enclosed in absurd magnetic fields while grad students sit safely in the room next door.  Or maybe I’m alone there.  But at least you like money.

Most universities with research programs have science.  And that science sometimes needs human subjects.  And usually those human subjects aren’t really subjected to anything that would be considered inhumane (as opposed to the kinds of things that inhuman animals are subjected to).  And sometimes, if you’re lucky, those human subjects can be you.

There are many human experiments out there that are really quite mild (ask a few questions, fill in a few surveys, watch a few videos, spit into a cup, etc.), but they’re pretty interesting and can pay up to $15-$50 per hour for your trouble.  Sure, you’re not going to make a living off of it (though some have, and there is a legitimate debate over a minimum wage for guinea pigs), but it’s a nice diversion that can help you rationalize buying a new wetsuit (true story).

So how do you get involved?  If you live in Berkeley, just sign up for the Research Subject Volunteer Program (RSVP) and you can participate in all kinds of cool studies (mostly involving psychology – so it’s just fun games/questions).  On top of that, if you do any kind of MRI experiment, you’re very likely to get a killer picture of your brain (as shown above).  If you’re not fortunate enough to find yourself in the bay area, I would recommend doing a quick google search for “Research Subject Volunteer” + “Your Local Big University” and you’re likely to find some results.

So far I’ve participated in a few experiments between Berkeley and UCSF.  I played some memory games in an MRI machine and got a picture of my brain (I thought the machine was relaxing and even started to fall asleep – my roommate, on the other hand, was intensely uncomfortable and vowed to never again volunteer for unnecessary cranial imaging).  I’ve also watched some violent videos, to which my responses are presumably being correlated with genetic information found in my spit.  So it’s all cool stuff.

They even have an experiment that will give you $210 to play video games for a month:

Relationships and Social Cognition Lab emotion and video games Three part study, involves two laboratory visits during which physiological responses will be monitored. In between lab visits participants will be asked to play computer games daily for half an hour for 30 days.  Compensation: up to $210  Special Requirements:completed high school in the US, fill out screener: http://www.surveymonkey.com/s.aspx?sm=GWjkpIDz5amM1XaOd_2fZZ8A_3d_3d  Location: UC Berkeley Campus

An interesting aside: in researching this article (yes, there was some “research” involved), I found that the Tufts School of Dental Medicine is the first result in a google search for “become a research subject”.  I just particularly enjoyed how they “broke it down” for the laypeople:

What Is Research?

• Research is a study that is done to answer a question.

• Scientists do research because they don’t know for sure what works best to help you.
• Some other words that describe research are clinical trial, protocol, survey, or experiment.
• Research is not the same as treatment.

Maybe, just maybe, your diggs and reddits and tweetiemabobs will push the google-rated significance of this article above those tooth jockies at Tufts.  Yes We Can!

Little-known fact:  I do it for the adventure and mystery.

Note that Google’s skilled text parser caught our hidden innuendo:

This group name is not suitable.  You cannot include the text “anal” in the group name.

This is particularly amusing considering Google’s close ties with a certain consumer genetics company in the bay area.  We ended up going with “DNA Journal Group” instead.  Thanks for keeping it clean, Google!
