Agreed exactly.
Just like I said it is kinda neat - that as you go faster, your mass increases, so it takes less acceleration to feel the same effect, so eventually you will be hardly accelerating at all, just before you hit the speed of light but you will never get there (the limit).
Now, I...
Well the whole reason Einstein (the given reason anyway) came up with the idea of equivalence principle relating to gravity is because he noticed the effects of inertia could be similar, so you could think of gravity in "reverse" - instead of gravity pulling us down, it's really our own inertia...
However in my analysis, objects would only fall back "down" if you either threw them upwards, or forwards (in the same direction as the ring's spin). If any object moves backwards it would never come down. Well, it might eventually, if it's backward velocity was not enough to counteract the...
Of course you can accelerate for as long as you like, and you never can get to the speed of light.
But the analogy falls apart is my point. You have to keep going faster and faster to keep up the gravitational force, because it does not work unless you are accelerating. And, the faster you...
Yes, but in this case I am not referring to moving in a circle. The room moves in a straight line.
I'm just pointing out that the illustration, while helping one to understand the ideas, it flawed in that it cannot work "forever". Also to go along with that, it does not help understand why a...
Sorry for so many questions.
In Einsteins equivalence principle, it states that an observer in a close room at 1G accel would not know the difference between that or whether he was standing on the Earth. This makes fine sense to me. But it also states as well that it is independent of...
Centrifugal "gravity"
Imagine a giant circular ring, which spins to generate a type of "gravity" (think of the video game "halo" even)
My problem with this is:
1. A man is walking along this spinning ring. He feels gravitational effects no doubt.
2. The man takes a ball, and tosses it...
Ok. It's been a long time since chemistry class.
Firstly, I'm investigating alternative techniques for cutting paper. Think, a normal sheet of computer printer paper. Disregard for the moment any chemical binders. Paper is close to 100% cellulose.
So, cellulose is a polysaccharide which...
From wikipedia:
Now then, what type of laser emits infrared? Think CO2..
I don't think a laser, however, will do what you need. It will simply heat up the water. Of course, this will encourage the separation of molecules to some extent. (maybe use hot water and then do electroylsis the...
"Generation" of gold, silver, copper elements
Since gold, and silver, and copper are all elements, I am a little confused - are they generated, or is there already only so much of each in the Earth, period?
I know I found some data on Wikipedia that indicated that the various elements can be...
Hm. All of these posts are interesting.
I too have always compared electrical inductance to physical inertia. I will agree they are not necessarily the same thing.
However, if we simply look at the behavioral level:
1. Current is applied thru a coil. The coil builds up a magnetic field. Upon...
