When people ask you for your last name ("apellido") for anything official, you need to be more careful than you realize, because they use a Spanish convention for surnames. ... The father's name is dominant, appears first, and is the one that appears in indices and such, and is used in everyday life. ... You only pass the paternal one to your children, so the child of John Smith Jones and Mary Lewis Nolan is Ann Smith Lewis. ... In Spanish, they're "Apellido Paterno" and "Appellido Materno". ...

The First Law (1): Energy is Conserved in a closed system: . ... We usually consider work and heat flow as the two kinds of energy . The Second Law (2): The Law of Entropy: . ... The amount of disorder increases . ... You can not go from a disordered system to an ordered system without inputting more energy (this is the most important attribute of the second law) . ... In no way can we recover work of that this disordered system without putting energy into the system. ... More on Thermodynamics . ...

How Precise is the Orbit of (99942) Apophis and how Probable is its Collision with the Earth in 2036? ... At present the orbit of asteroid (99942) Apophis and the forces acting on it are not known with sufficient accuracy to predict with certainty its motion after the close approach to the Earth in April of 2029. As a result of this approach the current heliocentric orbit of the asteroid will be changed by Earth's gravity. ...

... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...
