Time In

Start the clock

A modest proposal for improving football: the ‘time-in’

If you’ve ever noticed that football games slow to a predictable crawl at the end of each half, the time-in is the rule for you. The idea is simple: When the clock is stopped, for whatever reason, a coach could call a “time-in,” and force the clock to start up again. Think of it as the antimatter version of the timeout.

The time-in is so powerful that I recommend it be strictly rationed: each team would get only one time-in per season. The possibility of a sudden time-in would loom large in every coach’s mind at the most tense points in the game, introducing just enough concern and uncertainty to make the game different. Timeworn clock-management strategies would no longer be a given. And yet, for the average viewer on a Sunday, the game on the field would still be your father’s football.

Of course, this assumes that the time-in is used that game. If it hasn’t been used yet, it affects the game in a different, but more subtle way: the opposing team will simply have to assume that it might be used. Coaches would enter the realm of game theory: how do we calculate when it’s the best game to use it? And what if the other team is expecting us to think this way?

Those Who Can, Do. Those Who Can't, Explain.

Usain Bolt: The Science of Running Really Fast

Even without knowing the times, you can see that this is a special run. The first few seconds are fairly average, and as expected the acceleration trails off after around 40m, but then he just keeps going. Bolt covers 60-80m faster than 40-60m, somehow increasing his acceleration, and takes 80-100m at the same speed, with no significant deceleration.

Ice to See You

NY Times: For Winter Games in Vancouver, Ice Isn’t So Easy

“You can’t just go out there and make ice,” said Hans Wuthrich, in charge of the surface at the newly built curling arena, where the final step is a delicate spritz of scientifically configured water droplets strong enough to alter the course of 44 pounds of sliding granite.

The five ice specialists, each with deep Canadian ties, have extensive experience from previous Olympics. On behalf of ice, they helped design new locales and the upgrades to existing ones. They toured Vancouver’s water-treatment plants to study their product’s key ingredient. They ponder every ice-dooming possibility.
