Momentum Quotes - page 4
The conclusion seems to be irresistible that such laws of nature as the principle of conservation of energy, the principle of conservation of momentum and the law of gravitation are necessary consequences of our modes of measurement. They are, in fact, elaborately disguised identities which could have been predicted a priori by a being of sufficiently powerful analytical insight who fully understood all that is implied in the way we measure space-time intervals.
Ernest Barnes
Each of the most basic physical laws that we know corresponds to some invariance, which in turn is equivalent to a collection of changes which form a symmetry group. ...whilst leaving some underlying theme unchanged. ...for example, the conservation of energy is equivalent to the invariance of the laws of motion with respect to translations backwards or forwards in time... the conservation of linear momentum is equivalent to the invariance of the laws of motion with respect to the position of your laboratory in space, and the conservation of angular momentum to an invariance with respect to directional orientation... discovery of conservation laws indicated that Nature possessed built-in sustaining principles which prevented the world from just ceasing to be. There were fewer roles for the Deity to play...

In the autumn of 1884 I went to Paris. The spirit that greeted me was certainly more impressive than in Germany. I studied in a famous school. The French who I met there seemed to me not at all equipped. Traditional views. I was there for three years. I never found a talent. Among the Germans, in particular at the Academy of Munich, there was a lot more momentum. I admire the French painting from Watteau to Monet, otherwise there is nothing that can be said to be exceptional.

For the first time since 2007 there is political momentum behind fixing the immigration system. President Obama in his State of the Union speech reached out to the right-wing by saying illegal immigrants seeking citizenship will have to pay taxes, learn English and get in line behind people who are trying to enter the United States legally.
