LOG#007. Time dilation.

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

LOG#006. Lorentz Transformations(II).

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

LOG#005. Lorentz transformations(I).

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

LOG#003. Entropy.

“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

LOG#002. Information and noise.

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
