Dear God,
Thanks for the basketball. Really good. (gm)
Look, it’s your first tumbl post! How apropos! I like The Book of Basketball, but I am not a huge hoops fan. I thought Breaks of the Game was a little boring, for instance. (It could just be me and Halberstam, though.) I’m glad TBoB is pretty good, because I’ve been really, really down on Simmons, lately. I can see that he put in a lot of work and where.
I was going to read Breaks of the Game, probably off of his own recommendation, but it’s tough reading about people whose faces I wouldn’t recognize. Seven Seconds Or Less, on the other hand, was incredible because I had watched a lot of that team and the book filled in the gaps instead of creating the whole narrative… As for Simmons, I feel obligated to buy his book if only as a hat tip for the years of amusement. Glad to hear it’s actually good.

These things I say, may seem to offend
But not half as much, as I’d like to intend
Listening to you, reminds me of
A motor’s endless drone
And how the deaf are so damn lucky

Because an observer on the ground sees the satellites in motion relative to them, Special Relativity predicts that we should see their clocks ticking more slowly (see the Special Relativity lecture). Special Relativity predicts that the on-board atomic clocks on the satellites should fall behind clocks on the ground by about 7 microseconds per day because of the slower ticking rate due to the time dilation effect of their relative motion.
Further, the satellites are in orbits high above the Earth, where the curvature of spacetime due to the Earth’s mass is less than it is at the Earth’s surface. A prediction of General Relativity is that clocks closer to a massive object will seem to tick more slowly than those located further away (see the Black Holes lecture). As such, when viewed from the surface of the Earth, the clocks on the satellites appear to be ticking faster than identical clocks on the ground. A calculation using General Relativity predicts that the clocks in each GPS satellite should get ahead of ground-based clocks by 45 microseconds per day.
