Looks like I’m going to be having about as close as I get to a birthday party down at Kulture Friday night.
So in addition to Nathans photographs, you get to see me. If you like Nathans photographs and hate me, you are just going to have to make that decision on your own.
Oh, and it’s only a day late for Todd’s birthday as well, who promises to be in attendance.
My birthday is this weekend. Perhaps I should do something. I usually don’t bother.

Some friends of mine are opening a new resturant/bar in Brevard, NC. It’s called The Square Root.
There’s an article about The Square Root in the Hendersonville News.
They are opening up tomorrow. So if you are in the area, drop by.
Just talked to them on the phone. It was kind of weird exchanging stories about trying to open a bar (at least, by proxy, in my case). Being non geeks, they don’t quite have the web site up yet.
Anyone in the Raleigh area know of a bank/etc that has change counting machines that do not charge a large fee like the coinstar machines. I’ve got several years worth of change I need to get rid of (by my estimate, ~$900) and would prefer to avoid the coinstar machines. Bonus points if it’s a BB&T.
2006? Meh.
Hillman’s Top 100 Wonders Of The World
Kind of depressing that of the 100 items on that list, I’ve only see 1. And that was “New York Skyline” at #84.
A panther, a cougar, a mountain lion, and a puma are all the same thing.
The turbopumps on the space shuttle generate about 85000 hp
I’m tired of these motherf***ing planes on this motherf***ing treadmill.
The plane and treadmill problem is mentioned here, and here and here.
Basically, a jet plane is setting on a treadmill/conveyor belt. The treadmill is setup so it will match the exact speed of the plane in the opposite direction.
Will it take off?
My answer is yes. It would take off more or less normally. With the exception that the wheels will be spinning twice as fast as normal.
Why? F=MA.
The jet engines excert a huge force in one direction. The treadmill however, is only able to exert a very small force in the opposing direction.
Not convinced? Think of it this way. The plane is standing still on the treadmill with the engines off. You have a cable attached to the front of the plane. The treadmill starts up. How much force does it take to keep the plane from moving? Not that much. The wheels can only provide so much force, mostly just the rolling friction from the wheels.
Now try the opposite. The treadmill is off. You are holding the cable behind the plane. The jet engines start up and roll up to full throttle. How much force does it take to keep the plane in place. A frigging lot.
Unbalanced forces means a net force. Which means acceleration. Which means the plane moves. And takes off.
