Keeping Racecars on the Racetrack


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.”

Why Drying Tracks Takes So Long


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.

NASCAR Concussions II: A Screening Test to Avoid Relying Entirely on the Driver


I was lucky enough to speak with Dr. Mark Lovell, an innovator in neurocognitive testing inbetween talks at a conference he was attending. Dr. Lovell came to my attention as the developer of the ImPACT (Immediate Post-Concussion Assessment Testing) test, which was one of the tools used to evaluate Dale Earnhardt, Jr.’s concussion.
