First law defined as conservation of energy. Second law defined as paraconservation of entropy. Entropy defined in terms of statistics. A discussion of whether a reaction will proceed spontaneously or not. This is related to the question of whether a reaction is reversible or irreversible. The ...
In the 128 pages of 《A First Course in General Relativity - 2nd Edition》:"The covariant derivative differs from the partial derivative with respect to the coordinates only because the basis vectors change."Could someone give me some examples?I don't quite understand it.Tanks! GR191511 Thread...
first described what are now calleddiffractioneffects, in which light passing an obstacle is seen to penetrate into the geometrical shadow. In 1676 the Danish astronomerOle Rømerused his measurements of the changes in the apparent orbital periods of the moons of Jupiter over the course of a ...

of course,themselves set up by a very rich inpidual who had decided what he wanted to do with his own money.Time,rather than intention,has given them legitimacy.As much as some scientists may complain about the new awards,two things seem clear.First,most researchers would accept such a ...
I first became aware of David Z Albert when I was an undergraduate at a small Lutheran college in rural Iowa. On its top floor, the Wartburg College library had a large painting of Martin Luther, our hero, overseeing a bonfire of Catholic theology. But in the basement, where the unburnt...
position vector formula to find the position vector of any point in the xy-plane, we should first know the point coordinates. consider two points a and b whose coordinates are (x 1 , y 1 ) and (x 2 , y 2 ), respectively. to determine the position vector, we need to subtract the...
