Just how many current-day F&SF writers have a student/teacher relationship to Orson Scott Card through Uncle Orson's Writing Class and Literary Boot Camp or similar endeavors?

A washer in the bathroom tap is shot and the tap has suddenly a substantial flow. I'd rather not waste water for the time it takes a plumber to fix the problem and so I've shut off the water in the basement.

Is there some horrible failure mode I am overlooking, some obvious way turning the water off will lead to a calamity? I've filled the cats' water dish and their brita.

[Update: we have the sound of silence from upstairs]

There's one driver whose accelerations are such that passengers are well advised to hang onto something if they are not seated. I've had other passengers end up in my lap during a accelerate/decelerate cycle and once a baby carriage flipped over its front wheels but was caught before the baby was ejected. The driver in question is a nice person [1] but I dread getting on the bus with them driving.

The thing is, it doesn't feel like the magnitude of the accelerations are that much higher than the ones used by other drivers who aren't knocking people over and I can't figure out what else could be a factor. Is it the combination of stops and starts? They seem to spend a lot of time adjusting speed up and down.


1: Unlike the driver last week who mocked an old lady because the old lady felt that she could not negotiate the height of the rear exit step.

Relativistic Star Ship Calculator

In the Olden Days, when space craft were going to keep improving as quickly as after WWII, the interstellar medium was not thought to be so thin near us and that annoying Mr. Heppenheimer had not yet pointed out that Bussard ramjets appear to radiate energy one billion times as efficiently as they generated it, young fanciers of interstellar exploration would plug in values like 1 g and 12 light years and get heartening results like "Less than six years to Tau Ceti from the point of view of the ship".
