The Story of Gamma-ray Bursts

Gamma-ray bursts are flashes of gamma rays connected with extremely energetic explosions in distant galaxies. They are the most luminous electromagnetic events occurring in the universe.

This illustration shows the life of a massive star as nuclear fusion converts lighter elements into heavier ones. When fusion no longer generates enough pressure to counteract gravity, the star rapidly collapses into a black hole. Energy may be released during the collapse along the axis of rotation to form a gamma-ray burst. (Credit: Nicolle Rager Fuller/NSF)

"The death star": BBC documentary on the first stars in the universe and gamma-ray bursts.

Moebius transformation

Moebius transformation of the plane is a rational function of the form
f(z)=(az+b)/(cz+d)
The variable z and the coefficients a, b, c, d are complex numbers satisfying ad − bc ≠ 0. Moebius transformations are named in honor of August Ferdinand Moebius.

Here is a short movie depicting the beauty of Moebius Transformations in mathematics, it shows how moving to a higher dimension can make the transformations easier to understand.

Animal Evolution: Phanerozoic Eon

The Phanerozoic Eon is the eon in which we live, the one during which abundant animal life has existed. I've just found this amazing video on YouTube, it shows the evolution of fish, amphibians, reptiles, dinosaurs, mammals, and primates, starting more than 500,000,000 years ago, and ending today.

The Hawking Paradox: Video

The strange and exciting mix of general relativity and quantum mechanics results in the so called black hole information paradox. The Discovery Channel show "The Hawking Paradox” explains that information lost in black holes could be saved in parallel universes where no black holes exist. See the complete 49 min video here:
