Try to talk while listening to yourself with some delay (as sometimes happens on mobile phones): Listening to yourself in the past is REALLY strange.
It is becoming more clearly to me now. Let me rephrase the findings up to now: So, we may not speak of changing mass, when we mention mass, we...
Special relativity has to do with converting speeds, masses etc from one inertial frame to another. So the formula m=m0/sqrt(1-v^2) would give...
Does that also hold for string-theory?;)
Since when is mathematics restricted by physical limitations...
infinitesimals Those infinitesimals are interesting. How should we represent them? First the definition from the previous link: from this...
Depends on the mathematics you are using! If you are using standard analysis then 0.99999.. equals exactly 1. If you are using non-standard analysis...
I have noticed that many physicists also use infinitesimals and not the limits.
f'(x) = lim ( f(x+h)-f(x) ) / h h->0 for continuous f.
Take a=2, then b is not in Q. I think numbers are artificial since they are invented by humans. They dont grow in nature (hmm maybe they grow in...
Now I am certain, Jeff = Eliza ! Han.
Re: Re:Han Baumer what do you mean by "more artificial"? Han.
Hmm, strange things happening here: people with their own pet-theories always refusing to learn about traditional science but still wanting to learn...
In fact all numbers are artificial: mathematicians just invent new sorts of numbers when they bump into problems. Suppose you want to count...
This is true if you are considering you and the rocket going at the same speed. But if accelaration is involved all changes. Consider the clock...
1) is because of the principle of equivalence: you can't tell the difference between accelleration or being in a gravitational field. When you...
40.6 metres I love Mathematica for these things: Solve[{s==1/2 g tf^2, tf + ts==3, s==ts*v}, {s, tf, ts}] /. {v -> 331.45, g -> 9.81}...
Yeah, I know, I took the easy way. But then again, it is a fun problem....
990 metres "it takes 3 seconds for the sound of the splash to reach him" so the distance is 3 (time taken) * 330 (speed of sound in air) = 990...
The earth is also rotating which causes you to hit the wall going down to the center of the earth. On your way down the earth you have to slow down...
Separate names with a comma.
