### C'mon U Penn!

The senior faculty of the Department of Africana Studies recently RSVP'd to U Penn's annual diversity dinner, saying thanks, but no thanks to this year's event (h/t Claude). The reason is that at last year's dinner they demanded to know why the president had not appointed a single minority to the upper administration during her tenure.
Her response was that she would not just bring in someone who is not qualified, a comment implying that none of the people in the room were qualified to serve in these positions, even though many of them serve in administrative capacities in departments and centers. In her closing remarks, President Gutmann reiterated her dedication to diversity within Penn’s administration, admitting that “a show beats a tell.”
President Gutmann’s “show” came on Jan. 17, when she announced the appointment of the new dean of the School of Arts and Sciences. Yes, a show beats a tell every time, and once again, she has shown that her commitment to diversity does not include her own administration. When presented with yet another opportunity to increase diversity at the highest levels of the University, she failed to do so after nine years at the helm.
The rest of the op-ed RVSP is here (see also this). While U Penn has made considerable progress in enhancing the diversity of its student body, diversity campus-wide is crucial. As one professor put it, “If you’re not diversifying the faculty that that student body sees, then what’s the point?” I wholeheartedly agree with this notion. Diversifying a university works best when done from the top down. It is hugely valuable for students of color, as well as women in the sciences, to see many examples of people like them in the positions of authority, such as professors and the administration, and not just as admins and custodians. As the authors of the op-ed put it:
The annual “diversity dinner” is indicative of cosmetic — not substantive — progress on diversity that we believe President Gutmann must address. Our decision not to attend this year’s dinner — and to share that decision with the Penn community — is not a petty one, nor is it one we’ve made lightly. Rather, it is based on a long overdue decision to forgo these meaningless gestures toward progress on diversity.
Only when issues of diversity are substantively engaged at the highest levels of our administration, not simply promoted as social events, will real change occur...

### 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…
