Hello, I am 18 years old and I am very interested in mathematics. I have only knowlegde of school-matematics (school-Analysis, school-stochastics and a little bit school-linear Algebra) but that's not really interesting. Its basically memorising given methods to solve exercises instead of...

Lets imagine following: We have an infinite set of numbers representing the time. Now if we want to know how much time has spent in a specific sequence of this infinite set we see that this is impossible because there is infinite time passed before this sequence and infinite time passed...

As I said: Sorry if stupid question - I have no math skills yet but only my interest in understanding the world.. But I have a question to your answer: If this would be so than Stochastics and staticstics wouldn't be possible or not? I mean: The stochastic prognose for getting side 0 in...

Is probability "saved somewhere and somehow"? sorry if stupid question...still at school...only know school-math... We have following example: We have a coin (with two sides 1 and 0) and we let it fall to the ground. The probability for each side to be on top is (1/2) or 50%. Now if...

Please watch the video first. Its only about 5 minutes long: http://www.youtube.com/watch?v=oRWwI61so5Q&NR=1 Thats really fascinating to me but I feel that somethings strange about it. Can you imagine this? As soon as he turns the machine on he could get messages from the future...

many thanks to everybody for the answers. Some answers are quite mathematical and hard to understand for me (17y-old student, 12th-grade) so I will need some time to understand and think about that. (I only had Integration and Differentiation (Analysis?) and no other higher mathematics yet)...

It don't needs to travel at infinite speed because the room at c speed, I think, is contracted so much that a photon (or anything else that fast) can reach every place in practically no time. But maybe that's my problem: How much is a room contracted for objecs at c? Maybe its not as much as I...

yes, but the important point to me is that something is able to travel at c ok, I chose a photon because its the only object i know which travels with c. Are there other objects that travel with c and therefore have no mass? And I just don't understand why a photon should not have a point...

Why? Photons are waves and particles, Particle-Wave-Dualism. Or not? Photons have no mass but they have energy. And because Mass=Energy and vv that doesn't matters. We know that Myons, which move nearly c, contract the room very much and time is passing much slower for them. Thats why they...

ok thanks. An article I just read bout quaternions says that there are even 8-Dimensional hypercomplex numbers (octonions), 16-Dimensional (sedenions) and new higher dimension-systems can be constructed with the Cayley-Dickson-Method (creates new systems with twice as much dimensions as the...

hello, does time stand still for objects which move with c, like photons? And is the room contracted so much that its a point for thus photons?

hello, first: excuse me if the question is stupid but I am still at school. my question: some days ago i came across imaginary numbers. You know what I mean - the imaginary number i^2=-1 and the imaginary numberline is not on the the same line as the other numbers. The imaginary numberline is...
