/sci/ - Science & Math

so how do i get up in the morning? Doess it help to sleep with clothes on, or maybe sleep on something less comfortable than a bed, like a couch? I really need to get some work done and sleeping 12 hours/day isn't helping

/sci/ physicists, I need a little help.

I'm relatively (no pun intended) new to SR, and have been going through my problem sets without too much trouble so far, but I'm stuck on a problem that doesn't seem particularly difficult. Still, I can't seem to straighten it out, so an explanation would be much appreciated.

The problem is related to a shuttle ship running from the back of a [very] long convoy of spaceships to the front. The convoy and the shuttle both keep their own clocks, and the shuttle travels at 0.9c relative to the convoy. I've calculated the total time elapsed for the journey (the convoy being 5 Lhrs long in its IRF), and have the convoy measuring time elapsed as 20000s, and the shuttle as 19595.918s according to their local clocks.

Now, I'm asked how much time the shuttle measures from the convoys local clock (as opposed to their own) shortly before their [abrupt] deceleration, and why this will differ to the time shown on their respective local clocks once the shuttle docks with the front of the convoy.

I get the impression that the shuttle will measure 19595.918s by the convoy's clock shortly before deceleration, but I can't elaborate upon the reason. Hopefully there's someone here who can help me out. Cheers!

...it's fucking sad the amount of times this pic is relevant.

dude, it's nasa.
they fuck up a lot.

Quick question; what would be the finished result of (x^2-6)^2-8?
