In our place people use to apply vegetable oil for head,( and to body at times) and have a bath after half an hour or so. They say it keeps them cool. A kind of effect induced by mint shampoo. I don't understand how it works. But would love to know it.

As the thread goes on I seem to understand it more and more. Now am almost satisfied. I had the same satisfaction some 10 years back. But somehow forgot everything as I have been away from physics for sometime. As you said the confusion arose when I messed up the frame of reference. THANK YOU...

Based on what you say, consider A and B traveling in opposite direction, there is a light source switched on from the side to which A is traveling to. Now won't A receive the light first followed by B after some time delay.

Now in Einstein's train paradox, lightning strikes at the ends of the train but the observer sees the light at the front end of the train first and then sees the light from the end. Why is that. if speed of light is constant no matter whatever frame of reference, both lights should be seen...

We have defined these relative speed equations such that we can never breach the speed of light. Why is that.

relative speed can be calculated by V_ab+V_ac/(1+V_ab*V_ac/c2). Then we will get the value as C. But my question is what made us to keep the speed of light as the limit. I understand that we need infinite energy to speed up a massive object to the speed of light. But in relativistic speed...

I have a doubt regarding the speed of light. What makes it impossible to achieve it. Why can't we have a relative velocity greater than that of C. Some say you should not apply common physical world logic in these fields. But, Consider we have 2 laser sources separated by 2c distances. Say we...
