Newton’s gravity reads: In extra dimensions, , , it reads For extra dimensions, if their size are much smaller than considered distances, , then by matching So, gravitational is weak in our … Continue reading

Happy New Year 2018, dear followers! Today is a special blog post! My 200th post! After a really terrible 2017 from the viewpoint of family, health and productivity, I wish this one will be a great year for me and … Continue reading

The marriage between gravity and quantum mechanics is “complicated”. The best physicists and brightest minds have tried, but only with partial success. String/superstring theory, now M-theory, is a curious story. The another story is canonical quantum gravity, or loop quantum … Continue reading

The year 2013 is coming to its end…And I have a final gift for you. An impossible post! This year was the Bohr model 100th anniversary. I have talked about this subject already, here, here and here. The hydrogen spectrum is very important in Astronomy, … Continue reading

In 1905, one of Einstein’s achievements was to establish the theory of Special Relativity from 2 single postulates and correctly deduce their physical consequences (some of them time later). The essence of Special Relativity, as we have seen, is that … Continue reading

In the next group theory threads we are going to study the relationship between Special Relativity, electromagnetic fields and the complex group . There is a close interdependence of the following three concepts: The classical electromagnetic fields and can be … Continue reading

Imagine that an idealised bug of negligible dimensions is hiding at the end of a hole of length L. A rivet has a shaft length of . Clearly the bug is “safe” when the rivet head is flush to the … Continue reading

The Batmobile “fake paradox” helps us to understand Special Relativity a little bit. This problem consists in the next experiment: There are two observers. Alfred, the external observer, and Batman moving with his Batmobile. Now, we will suppose that the … Continue reading

The topic today is to review a beautiful paper and to discuss its relevance for theoretical physics. The paper is: Comment on the cosmological constant and a gravitational alpha by R.J.Adler. You can read it here: http://arxiv.org/abs/1110.3358 One of the … Continue reading
