Why, if there is anything in supply and demand, life is the cheapest thing in the world. There is only so much water, so much earth, so much air; but the life that is demanding to be born is limitless. Nature is a spendthrift. Look at the fish and their millions of eggs. For that matter, look at you and me. In our loins are the possibilities of millions of lives. Could we but find time and opportunity and utilize the last bit and every bit of the unborn life that is in us, we could become the fathers of nations and populate continents. Life? Bah! It has no value. Of cheap things it is the cheapest. Everywhere it goes begging. Nature spills it out with a lavish hand. Where there is room for one life, she sows a thousand lives, and it's life eats life till the strongest and most piggish life is left.

In every department of physical science there is only so much science, properly so-called, as there is mathematics.

Mathematics is the queen of the sciences

Opinions” are the cheapest commodities on earth.

It turned out I was pretty good in science. But again, because of the small budget, in science class we couldn't afford to do experiments in order to prove theories. We just believed everything. Actually, I think that class was called Religion. Religion class was always an easy class. All you had to do was suspend the logic and reasoning you were being taught in all the other classes.

Whatever the cost of our libraries, the price is cheap compared to that of an ignorant nation.

Anything that just costs money is cheap.

Mathematics consists in proving the most obvious thing in the least obvious way.

The era of garage biology is upon us. Want to participate? Take a moment to buy yourself a molecular biology lab on eBay. A mere $1,000 will get you a set of precision pipettors for handling liquids and an electrophoresis rig for analyzing DNA. Side trips to sites like BestUse and LabX (two of my favorites) may be required to round out your purchases with graduated cylinders or a PCR thermocycler for amplifying DNA. If you can’t afford a particular gizmo, just wait six months — the supply of used laboratory gear only gets better with time. Links to sought-after reagents and protocols can be found at DNAHack. And, of course, Google is no end of help.

Mathematics is the science which draws necessary conclusions.

Mathematics is not a science from our point of view, in the sense that it is not a natural science. The test of its validity is not experiment. We must, incidentally, make it clear from the beginning that if a thing is not a science, it is not necessarily bad. For example, love is not a science. So, if something is said not to be a science, it does not mean that there is something wrong with it; it just means that it is not a science.

Science is simply common sense at its best, that is, rigidly accurate in observation, and merciless to fallacy in logic.

Physics. Some say this science is fundamental; I say it’s a bunch of unnecessary regulations. Physics is the ultimate Big Government interference — universal laws meant to constrain us at every turn.

The cost of scientific advance is the humbling recognition that reality was not constructed to be easily grasped by the human mind. This is the cardinal tenet of scientific understanding: Our species and its ways of thinking are a product of evolution, not the purpose of evolution.
