Todd Barry: Germaphobe
It's paralyzing being a germaphobe; lots of places are really paralyzing to me. Laundromats have these baskets on wheels -- some guy will come in with a big bag of disgusting laundry, put it in the basket, move it into the washer. And I'm supposed to take my clean laundry out of the dryer, put it in that exact same basket. I don't mind something having a dual purpose but can't it be like, 'What's that big green box over there?' 'Oh that's a dumpster and we also use that to store soup.'

Leap secondIn 1972, the first leap second day, one second was added to the world's time in order to keep the super-accurate atomic clocks in step with the Earth's rotation. Since the adoption of this system in 1972, firstly due to the initial choice of the value of the second (1/86400 mean solar day of the year 1900) and secondly to the general slowing down of the Earth's rotation, it has been necessary to add over 20 seconds to Coordinated Universal Time (UTC).[Image: part of the master clock system at the U.S. Naval Observatory.] |
