### History

We know the battle ahead will be long, but always remember that no matter what obstacles stand in our way, nothing can withstand the power of millions of voices calling for change.

We have been told we cannot do this by a chorus of cynics who will only grow louder and more dissonant in the [time] to come. We’ve been asked to pause for a reality check. We’ve been warned against offering the people of this nation false hope.

But in the unlikely story that is America, there has never been anything false about hope. For when we have faced down impossible odds; when we've been told that were not ready, or that we shouldn't try, or that we can't, generations of Americans have responded with a simple creed that sums up the spirit of a people.

Yes we can.

It was a creed written into the founding documents that declared the destiny of a nation.

Yes we can.

It was whispered by slaves and abolitionists as they blazed a trail toward freedom through the darkest of nights.

Yes we can.

It was sung by immigrants as they struck out from distant shores and pioneers who pushed westward against an unforgiving wilderness.

Yes we can.

It was the call of workers who organized; women who reached for the ballot; a President who chose the moon as our new frontier; and a King who took us to the mountaintop and pointed the way to the Promised Land.

Yes we can to justice and equality. Yes we can to opportunity and prosperity. Yes we can heal this nation. Yes we can repair this world. Yes we can.

### 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…

### 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…

### The Long Con

Hiding in Plain Sight

ESPN has a series of sports documentaries called 30 For 30. One of my favorites is called Broke which is about how professional athletes often make tens of millions of dollars in their careers yet retire with nothing. One of the major "leaks" turns out to be con artists, who lure athletes into elaborate real estate schemes or business ventures. This naturally raises the question: In a tightly-knit social structure that is a sports team, how can con artists operate so effectively and extensively? The answer is quite simple: very few people taken in by con artists ever tell anyone what happened. Thus, con artists can operate out in the open with little fear of consequences because they are shielded by the collective silence of their victims.
I can empathize with this. I've lost money in two different con schemes. One was when I was in college, and I received a phone call that I had won an all-expenses-paid trip to the Bahamas. All I needed to do was p…
