I'm no expert, but I'll take a stab here.
If you were able to completely stand still in space and did not move at all, you'd not be moving through space - only through time.
Now, imagine you're in a spaceship with a speedometer, and you slowly accelerate. As you speed up, you move less...
My motivation was I was wondering, if there were people on that big planet and they were communicating with each other about what they saw (say, one is at the equator of the planet getting swallowed into the hole, while the other is at the pole), how would they perceive each other?
Much...
Hey all. Thanks for the response. I understand what you're saying. Nugatory's comment, in particular, helped me realize you could never observe the O state, which was where I was stumbling on.
So now that question 2 has been answered, anybody have any ideas on question 1?
If you were...
Hi all. Thanks for the answers. I'd just like to clarify my questions :)
Nugatory - Maybe, but I have measured the spin, if and only if you will get the opposite. Which means, if you get the opposite, I must have measured the spin.
bcrowell - Go through means, if the black hole is an egg and...
Hey all! Two things came to my mind about black holes, and I hope some of you can help me out :)
1. Say you have a non rotating, chargeless black hole of a certain size. Its radius will be R.
If you go through the black hole, from your perspective then time will be fine, right? Then that...
Hi haruspex. I figured it out. I'll say it here since it might be interesting to you guys =)
It's signal detection theory that should be used in this case, because it can identify hits, false alarms, misses, and correct rejections (basically signal present-response present; signal...
Hi. Thanks for the quick response :)
What I'm trying to do is something like in this article here (under Discrete Stimuli). It's basically how to get how strong is the signal over the noise in an experimental set up? I don't quite understand the article so I'm looking for help (and I've only...
So it's simply the average of the test scores divided by the average of the part they got wrong? Isn't noise the variance of the signal, rather than the incorrect answers?
The way I understand signal to noise ratio is through the gauge r&r, but that requires students to retake the same test...
I've been trying to figure out how to get the signal to noise ratio of a completely multiple choice type exam. I can't do it and it's driving me nuts, so finally I found this website and decided I'd ask. :D
Say you let your students take a multiple choice test and you are able to get all...
