Publisher's Synopsis
Book Excerpt: "All right--but I'll bet it's slower than the rise of a toy balloon." Seaton threw down the papers and picked up his slide-rule, a twenty-inch trigonometrical duplex. "You'll concede that it is allowable to neglect the radial component of the orbital velocity of the earth for a first approximation, won't you--or shall I figure that in too?""You may ignore that factor.""All right--let's see. Radius of rotation here in Washington would be cosine latitude times equatorial radius, approximately--call it thirty-two hundred miles. Angular velocity, fifteen degrees an hour. I want secant fifteen less one times thirty-two hundred. Right? Secant equals one over cosine--um-m-m-m--one point oh three five. Then point oh three five times thirty-two hundred. Hundred and twelve miles first hour. Velocity constant with respect to sun, accelerated respecting point of departure. Ouch! You win, Mart--I'd kinda step out! Well, how about this, then? I'll put on a vacuum suit and carry rations. Harness outsRead More
