Watch Ferrari’s F1 pit crew do a pit stop in around two seconds. We had to watch this multiple times so that we could figure out what each crew member’s two second task was and how they were doing it so quickly. Pretty incredible. From Autosport.com, via Kottke:
With three people per wheel, two jack operators, and a handful of mechanics fulfilling other functions, each pit crew comprises nearly 20 people…
They are drilled incessantly at both the factory and during race weekends, with hundreds of pitstop practices until the process is instinctive.
Machines make snow the same way nature does, by freezing water droplets. But they do it a few feet above the ground, rather than in the much colder conditions high in the atmosphere. Snowmaking machines employ a few thermodynamic tricks to help, but at times there is a limit to what physics can do…
…a droplet may not freeze entirely during the few seconds it takes to fall to the ground — what snowmakers call hang time.
“We’re basically making eggs,” Mr. Moulton said — icy shells around still-liquid centers.
From the National Film Board of Canada, this is Quebec director Gilles Carle’s The Rink. Details we noticed on this idyllic Sunday in 1962: everyone’s warm breath in the cold air, there are no helmets on the hockey players, there are no visible logos or designs on the clothes like there are today,that ladder obstacle course looks fun, and bright red coats look absolutely amazing against the white snow and ice.
