### Professing with Depression

I just read an excellent article by an MIT professor, Prof. John Belcher. He describes his decent into full-on clinical depression, and his inspiring recovery with the assistance of modern medicine (yay science!). I found it enlightening and reassuring to read his harrowing tale

It was the perfect storm. My physical coordination went. My thought processes became disordered. I had a hard time, for example, simply reciting the Pledge of Allegiance. I became lethargic, and had a hard time getting out of bed in the morning. Sleeping all the time seemed like a good option. I retained a certain detachment as I was sinking into depression. “So this is what it feels like to become clinically depressed” I would say to myself.

I also learned that there is a big difference from the acute anxiety that I suffer from, and the crushing depression that can cause a person to hole up in their house, unable to face the challenges of day-to-day life. I've seen it happen in my family, my friends and the people around me in academia. It's a real problem and it impedes progress in our field. We must face this source of inefficiency (and unhappiness) in our community. The most effective thing we can all do is to start to de-stigmatize mental health problems and the medication that solves them.

...This term I am teaching in and co-administering 8.02, a class with 830 students, along with Peter A. Dourmashkin ’76. We both know from long experience that it is statistically inevitable that a handful of our 8.02 students will get into trouble this term, with their own perfect storm, and that clinical depression is one of the possible outcomes. I am no doctor, but I do recognize the symptoms of depression. If a student comes to me with troubles of any kind, I always tell them to go to S3 or Mental Health. In case depression is the cause of the trouble, I also share with them that I have been clinically depressed and am on Prozac, and that there is no shame in that.
We should all be thankful that we live in this day and age, when these medications and treatments are available. We should not avoid them. In the words of Grace Taylor, “It’s not you, it’s a disease.”

### On the Height of J.J. Barea

Dallas Mavericks point guard J.J. Barea standing between two very tall people (from: Picassa user photoasisphoto).

Congrats to the Dallas Mavericks, who beat the Miami Heat tonight in game six to win the NBA championship.

Okay, with that out of the way, just how tall is the busy-footed Maverick point guard J.J. Barea? He's listed as 6-foot on NBA.com, but no one, not even the sports casters, believes that he can possibly be that tall. He looks like a super-fast Hobbit out there. But could that just be relative scaling, with him standing next to a bunch of extremely tall people? People on Yahoo! Answers think so---I know because I've been Google searching "J.J. Barea Height" for the past 15 minutes.

So I decided to find a photo and settle the issue once and for all.

I then used the basketball as my metric. Wikipedia states that an NBA basketball is 29.5 inches in circumfe…

### Finding Blissful Clarity by Tuning Out

It's been a minute since I've posted here. My last post was back in April, so it has actually been something like 193,000 minutes, but I like how the kids say "it's been a minute," so I'll stick with that.
As I've said before, I use this space to work out the truths in my life. Writing is a valuable way of taking the non-linear jumble of thoughts in my head and linearizing them by putting them down on the page. In short, writing helps me figure things out. However, logical thinking is not the only way of knowing the world. Another way is to recognize, listen to, and trust one's emotions. Yes, emotions are important for figuring things out.
Back in April, when I last posted here, my emotions were largely characterized by fear, sadness, anger, frustration, confusion and despair. I say largely, because this is what I was feeling on large scales; the world outside of my immediate influence. On smaller scales, where my wife, children and friends reside, I…

### The Force is strong with this one...

Last night we were reviewing multiplication tables with Owen. The family fired off doublets of numbers and Owen confidently multiplied away. In the middle of the review Owen stopped and said, "I noticed something. 2 times 2 is 4. If you subtract 1 it's 3. That's equal to taking 2 and adding 1, and then taking 2 and subtracting 1, and multiplying. So 1 times 3 is 2 times 2 minus 1."

I have to admit, that I didn't quite get it at first. I asked him to repeat with another number and he did with six: "6 times 6 is 36. 36 minus 1 is 35. That's the same as 6-1 times 6+1, which is 35."

Ummmmm....wait. Huh? Lemme see...oh. OH! WOW! Owen figured out

x^2 - 1 = (x - 1) (x +1)

So $6 \times 8 = 7 \times 7 - 1 = (7-1) (7+1) = 48$. That's actually pretty handy!

You can see it in the image above. Look at the elements perpendicular to the diagonal. There's 48 bracketing 49, 35 bracketing 36, etc... After a bit more thought we…
