		<description><![CDATA[Ryan Newman escaped NASCAR sanctions for his comments immediately after being discharged from the infield care center at Talladega.

“They can build safer racecars, they can build safer walls, but they can’t get their heads out of their asses far enough to keep them on the race track and that’s pretty disappointing, and I wanted to make sure I get that point across," he said. “You all can figure out who ‘they’ is."]]></description>

		<description><![CDATA[A quick post for my friend, @TheOrangeCone that I'll expand on later (I have theater tickets tonight!)

@TheOrangeCone asked why Kurt Busch went airborne in the Talladega crash.  The answer is the same for all the cars that end up in the air:  when a car rotates (so that its side or its back is leading instead of its front), it looks an awful lot like an airplane wing -- a shape that is optimized to generate lift.]]></description>

		<description><![CDATA[Water is critical to the existence of human life.  Why do you think we spend so much time looking for it on other planets?

It is, however, less than desirable on a racetrack.  Water gets between the tires and the track, which decreases friction.  Decreased friction means lower speeds and higher probability of crashing.]]></description>

		<description><![CDATA[Why does it takes so long for a track to dry?  Why does humid weather make track drying take even longer?

Air is a mix of gas molecules:  mostly (78%) nitrogen, about 21% oxygen, the rest misc. gases.  The composition is pretty uniform with the exception of how much water is in the air.   The absolute humidity is the amount of water in some chosen volume of air, for example, how much water vapor is in one cubic meter of air.  Air can only hold so much water vapor and that amount depends on the temperature and pressure.  Dry air would be no ounces of water in a cubic foot of air.  If the vapor is saturated at 30 degrees centigrade (86 degrees Fahrenheit), then the amount of water could be up to three one-hundredths of an ounce of water per cubic foot.]]></description>

		<description><![CDATA[We'd been hearing rumors of penalties stemming from Kansas and everyone expected them to be announced Tuesday.  Since penalties usually have some scientific component, I was sort of hoping for some new material.  Tuesday came and went.  Nothing.  Wednesday, all heck broke loose as penalties were announced for the No 20 JGR car (engine issues) and the No 98 ThorSport truck.
The more interesting -- and less discussed -- penalty is the ThorSport/Johnny Sauter one.  (It was a tough week for Wisconsin drivers).  The team was docked 25 points, which is pretty huge for the Truck Series and the crew chief fined $10,000.  (I realize that seems small when compared to the Sprint Cup Series penalties, but the Truck Series has correspondingly lower purses and salaries.)]]></description>

A biomedical physicist/radiation oncologist from UC-Irvine who had just gone to his first NASCAR race at Auto Club Speedway had a question about my book, The Physics of NASCAR (which, by the way, you don't have to be a physicist to read.  In fact, it's probably better if you're not.)]]></description>

		<description><![CDATA[A short note on Denny Hamlin's comments on the Gen-6 car and subsequent fine. 

I've talked to a lot of the people in the trenches involved in designing and creating the Gen-6 car.  That includes people from manufacturers and teams.  All of them have said that the development of the Gen-6 car is a major sea change for NASCAR.  This is the most collaborative that NASCAR has been with introducing a new car in some time.  Manufacturers and teams were consulted and they all feel that their opinions mattered and were taken into consideration.   This was a very, very different process than the COT introduction, which was designed by NASCAR and plans delivered to teams.]]></description>
