Relativity part...7

After understanding the concepts of relativity and knowing that time and space are not absolute as Newton told us instead they follow Einstein's theory of special relativity. Now I am going to go in depth ocean of time and space and let us figure out why these two simple known words are so difficult to understand and believe me it's really difficult and it requires deep imagination. So, today's chapter is about simultaneity. is everything in this universe happening simultaneously. If no then why or if yes then with respect to whom. 7.1 The Relativity of Simultaneity In order to understand the concept of simultaneity let us imagine we are calmly sitting in our spaceship which is in deep space and suddenly 2 other spaceships approach from opposite direction and pass each other as shown. They have equal velocities. Just as they pass we set off bolts of energy at points x1 and x2 simultaneously from our point of view. But are they simultaneous to the passengers i...

Physics...

Physics is the branch of science that deals with the study of matter and energy. If anyone wants to understand how universe behaves it is absolutely for them. From the smallest particle to the largest galaxy every question must have a logical answer . The thing that make physics beautiful is the mathematics. The use of mathematics is necessary to understand this world around us in the most simplest way. But physics is not just about equations instead it is about how one looks out at the outside world and have curiosity to understand that phenomena . From centuries people have tried to understand different phenomena happening around them but only those people have got the success who asked the right questions for example it is myth that Newton discovered gravity when apple falled on him but the real thing was that he just saw an apple falling from the tree and at the same time he observed Moon in the orbit then he asked himself "if the apple falls does the moon also fall" and...

Relativity...Part 4

Einstein about Space and time Now we have come to know that Einstein imagined time as a dimension. It means size of the object is going to change as the rate of time changes for that particular object. But how is this possible we don't feel a change in our sizes even when we are in motion. So one thing what we have to clear now is that time is not we think instead to understand time we have to think like Einstein. Einstein said that in order to keep the speed of light constant space and time change themselves now the question is at what rate they change themselves Einstein published this paper in 1905 what he later called "time dilation" in which he has given us the equation that shows at what rate time gets dilated for the object which is in motion with respect to the other frame of reference which is in rest. But just memorizing the equation will not help us to understand. In order to understand the true behaviour of time one has to imagine the ...

Relativity...Part 2

After understanding Newtonian mechanics now it is time to understand where the problem exists. One cannot doubt Sir Issac Newton because we all know him from our childhood his equations of motion are so accurate that one can easily apply them to go to Sun or even any other place in the universe. Einstein himself was a very big fan of Newton. After understanding Galileo's principle of relativity one can check that it is impossible to say which objects are at rest or which are in motion. Everything is relative. The problem comes is with Light. Maxwell showed through his equations which he published in 1873 that light is an electromagnetic wave and its velocity is about 300000km/sec in vacuum. Special Relativity is because of light Now what is so special about light is we don't really understand light too. First of all its speed is something which is very hard to imagine . Can you imagine urself going with the speed of light, if you then one can easily go around the Ea...
