I don't know if you know what a standard deviation is and how errors are treated in physics, so I try to explain it to you in a simpler way...Every result of a measurement (for example x) in physics is given with an error called sigma: σ. This means that the probability that the real value of...

There's an error in your last calculation... I'=m(d)^2+2m(2d)^2=m(d)^2+8m(d)^2=9m(d)^2 Meaning that the ratio between I' (after the masse were interchanged) and I is 9/6=3/2. But I'm not sure I've understood your problem...

You should know that a complex number can be represented as a vector in the gauss plane, where te x-axis is the Real axes and the y-axis is the Imaginary axis. Take for example the complex number z=a+ib (where a and b are real), it can be represented by the vector (a,b). You can use also a polar...

I think it's quite correct, but there could be some errors in calculation..anyway: http://spiro.fisica.unipd.it/~mimo/altro/sol.JPG

I think Classical Physics could be defined as an approximation of what Quantum Physics and Relativity discovered...I mean...The laws of classical physics doesn't change so much for our "order of magnitude", as a matter of fact they almost coincide with the "new physics" law... but when we handle...

So, this means that the "old John", who goes back to past, hasn't got free will, doesn't he?...Otherwise if he made decisions, he would change the course of the events... I like the comparison with the Prime Directive...very good :wink:!

But, for example, what may happen, if the "old John", after winning the timetravel, goes back in the past, meet the "young John" and prevent him from winning at the gameshow...? In my opinion there are too many paradoxes...:confused:I think time travel won't become a reality..:cry:

As for "where are the time travellers now?", Mallett sais: "My type of time-machine could only carry a time treaveller back to the moment the machine was turned on, and not one second before". So it's easy to understand why there aren't time travellers visiting us now: because the machine is...

I've just finished reading the book "Time Traveler - A scientist's personal mission to make time travel a reality", by Dr. Ronald L. Mallett, professor of physics at the University of Connecticut. In this book Mallett explains a new theory to travel back in time using a laser ring, which creates...
