Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.

There has been no discovery like it in the history of man. It puts into man's hands the key to using the fundamental energy of the universe.

Heat energy of uniform temperature [is] the ultimate fate of all energy. The power of sunlight and coal, electric power, water power, winds and tides do the work of the world, and in the end all unite to hasten the merry molecular dance.

But what sin is to the moralist and crime to the jurist so to the scientific man is ignorance.

Some of the beliefs and legends bequethed to us by Antquity are so universally and firmly established that we have become accustomed to consider them as being almost as ancient as humanity itself.

Four circles to the kissing come, The smaller are the benter. The bend is just the inverse of The distance from the centre. Though their intrigue left Euclid dumb There's now no need for rule of thumb. Since zero bend's a dead straight line And concave bends have minus sign, The sum of squares of all four bends Is half the square of their sum.
