If you preparing for the IPhO the syllabus this video covers virtually everything. I am not 100% if derivations of the Lorentz transformations are examinable but excellent to show where they come from. Also please note that at 17:46 it should say 99% of the speed of light, not 0.99%. Thank you and good luck preparing!

If we will use complex number in time dilation formula then result is -(time) means time running backwards.

and faster than light movement. I made a video about this: kzbin.info/www/bejne/fH-TmJ6ij797lbs I think of it as a mathematical curiosity though, but who knows what may be found in the years to come!

@@zhelyo_physicswow , i were not known that you have made video for this topic , last thing I want know your thoughts about nothing . What was there before the birth of the universe, did time begin with the Big Bang and when will time end?

If you only start from the two postulates, from there on, there will be circular analysis and circular descriptions, with one equation leading to another, and so forth. In such cases, Special Relativity(SR) is thus explained in parts, and not as a whole. In other words, the "Absolute" cause of the relativistic phenomena, is never being revealed. Thus what is being described, is only the effects, effects that are being accepted to have occurred without there even being a cause. The absolute description of SR, on the other hand, is tied to all of the equations simultaneously, rather than them being strung together in series. So....the SR phenomena only seem bizarre to those who have no true absolute understanding of SR at all.

Hi ZPhysics, at 11:00 how do you know t=2l/c?

@zhelyo_physics 2 жыл бұрын

you mean the writing on the left for a two stationary mirrors? Distance between the mirrors is l, i.e. 2l for going+coming back. And time = distance/speed. I.e. t=2l/c where c is the speed of light. Hope this helps!

@@zhelyo_physics Thanks for replying im still only 20 mins in but really enjoying it so far. Another question 24:58 why is it -vt and it sill from the point of view of the source. When you say refrence frame i am unsure what you mean

@@hamzaerfan anytime! Always glad to reply and thanks for the good questions. So we are splitting the motion then into two parts - one for the light going to the right, then one for the light going to the left. The two velocities must have opposite signs. Hope this helps! Glad you are enjoying the content, it's almost a whole semester worth of SR into 1 hour! : )

I am not uni yet so will I understand it with high school level math and physics?

@zhelyo_physics 2 жыл бұрын

Give it a try, you will very much impress your teachers! Actually I am amazed that it's mostly hard core algebra rather than any higher levels maths used to describe/derive most relativity concepts.
