Other striking consequence of Lorentz transformations and then, of the special theory of relativity arises when explore the concept of simultaneity. Accordingly to the postulates of relativity, and the structure of Lorentz transformations we can understand the following statement: What … Continue reading

Once we introduce the postulates of special relativity and we have deduced the generalization of galilean transformations for electromagnetism and mechanics, the Lorentz transformation. We can deduce some interesting results. Suppose we have two events and , whose coordinates of … Continue reading

Suppose two events happening in the S’-frame at the same point at different times. and . What is the temporal separation in the S-frame? According to Lorentz transformations, it is: or equivalently i.e. Of course, in the parallel case, if … Continue reading

These equations define the most general (direct) Lorentz transformations and we see they are not those in the previous post! I mean, they are not the one with the relative velocity in the direction of one particular axis, as we … Continue reading

For physicists working with objects approaching the light speed, e.g., handling with electromagnetic waves, the use of special relativity is essential. The special theory of relativity is based on two single postulates: 1st) Covariance or invariance of all the physical … Continue reading

The dream of every theoretical physicist, perhaps the most ancient dream of every scientist, is to reduce the Universe ( or the Polyverse if you believe we live in a Polyverse, also called Multiverse by some quantum theorists) to a … Continue reading

“I propose to name the quantity S the entropy of the system, after the Greek word [τροπη trope], the transformation. I have deliberately chosen the word entropy to be as similar as possible to the word energy: the two quantities … Continue reading

We live in the information era. Read more about this age here. Everything in your sorrounding and environtment is bound and related to some kind of “information processing”. Information can also be recorded and transmitted. Therefore, being rude, information is … Continue reading
