Lecture 3 Special Relativity

Length Contraction Just as in the previous post where we found out that time is dependent on the relative speed of an observer it is also true for length. Consider the experiment in post 2 where you are on a space station and a space ship flies past. Now have the experiment on the ship carried out in a way so that the flash of light sent out is in the direction of motion of the passing space ship. So now we have a flash of light sent out and reflected back to the source by a mirror. Let’s d

Lecture 2: Special Relativity

Second Lecture: Special Relativity Time Dilation Say we have a two asteroids heading towards each other and you are observing them from Earth. We see asteroid (A) moving at 0.8C (80% the speed of light) and we see asteroid ( B ) moving at the same speed but in the opposite direction. Now move our reference frame to asteroid (A) using classical velocity rules asteroid (B ) will obviously moving at 1.6C which is asteroid (A) speed minus asteroid (B ) speed (0.8C-(-08C)=1.8C). But hang on nothing

Lecture 1 Special Relativity

Hi all would just like to mention that the following blogs on special relativity are from my notes taken at uni. I have tried putting the ideas that were taught to me by my professor into my own words but really all the work is his and i've just stolen it ha ha har. I will not name my professor but all credit should go to him and thanks for letting me post this online. Hopefully it will help me in understanding the subject spark a few discussions and some people might find it an interesting r

Learning Special Relativity

What this all about? A few years ago while having a few drinks round a friend’s house, towards the end of the night we got talking about space and time. Being a sci-fi fan and educated to BBQ level on the subject I had some small ideas of how the universe works, anyhow we all had a great night talking about time slowing down and worm holes etc. The following day since I enjoyed the subject so much I decided to quit work and go back to school and learn physics (not the only reason but it started
