So What's Going on With Neutrinos These Days?

Remember those crazy neutrinos in Gran Sasso labs? Well the shocking results just got a little more convincing when new results were published  as the guys from the OPERA collaboration released new updated results.

So the results were updated as scientists in the Gran Sasso laboratories repeated their tests in a slightly different way. This time they fired very short and small pulses of neutrinos, which basically made their job at detecting the speed of the particles much easier. What they observed was that neutrinos still travelled faster than the speed of light in vacuum by about 0.00000006 seconds. So the shocking results survived the first test successfully. But don't start burning the books of relativity quite yet, as such profound results must be tested by at least one independent experiment to confirm. Also, even if neutrinos indeed travel faster than light, it's not the end of the world as there are some interesting theories, which suggest why neutrinos might travel faster than light (including time travel and other dimensions).

More on Faster than Light Neutrinos

So as the problem of the faster than light neutrinos at the OPERA experiment at CERN is still hot, let's check out this video about the physics behind detecting neutrinos and other strange but interesting stuff regarding the famous discovery at Gran Sasso.

A Great Book to Learn General Relativity

When it comes to GR, it's easy to find good books, which explain you the basics and the non-mathematical side of the subject, however, it's really hard to find a book, which would explain the basics of mathematics of GR in a easy to understand way. Thus I would like to share my experience of reading a book called "Firs Course in General Relativity" by Bernard Schultz.

As the books half title says - "Clarity, readability, and rigor combine in the second edition of this widely used textbook to provide the first step into general relativity for undergraduate students with a minimal
background in mathematics." This is truely the case, because the book is written in a easy to understand way.

The book contais theory, including special relativity in algebraic form and geometric form and general relativity basics. Furthermore, it has some exercises with solved examples.

From my own experience I can say that it's one of the best books to get the basics of both SR and GR. The difficulty level is not over the top like in the most of similar books (I'm a fresher in Physics, and my knowledge in maths and physics is basically enough to read and understand this book). Also, it's a great book to refresh your knowledge of SR and GR.

Thanks for reading!
