The underlying reason for convergence seems to be that all organisms are under constant scrutiny of natural selection and are also subject to the constraints of the physical and chemical factors that severely limit the action of all inhabitants of the biosphere. Put simply, convergence shows that in a real world not all things are possible.
The nature of the chemical bond is the problem at the heart of all chemistry.
Radioactivity is shown to be accompanied by chemical changes in which new types of matter are being continually produced. ... The conclusion is drawn that these chemical changes must be sub-atomic in character.ernest rutherford
I figure I've done what I could do, more or less, and now I'm going back to being a chemical; all we are is a lot of talking nitrogen, you know...Arthur Miller
When finally interpreted, the genetic messages encoded within our DNA molecules will provide the ultimate answers to the chemical underpinnings of human existence.
[I]f you allow someone like Saddam Hussein to get nuclear weapons, ballistic missiles, chemical weapons, biological weapons, how many people is he going to kill with such weapons? He's already demonstrated a willingness to use these weapons; he poison gassed his own people. He used poison gas and other weapons of mass destruction against his neighbors. This man has no compunctions about killing lots and lots of people.
The Regime has become so smug it can't tell the difference among the revolutionary, the innovative, or the merely various. The high command knows so little about the outside that if I came back with a fully equipped chemical laboratory and told them I'd found it in a cave, they'd probably believe that, so long as I brought it back peicmeal in my saddle bags, thus proving I hadn't known it was there beforehand.sheri s. tepper
It is true that my discovery of LSD was a chance discovery, but it was the outcome of planned experiments and these experiments took place in the framework of systematic pharmaceutical, chemical research. It could better be described as serendipity.
Psychiatrists look for twisted molecules and defective genes as the causes of schizophrenia, because schizophrenia is the name of a disease. If Christianity or Communism were called diseases, would they then look for the chemical and genetic “causes” of these “conditions”?thomas szasz
In the opinion of one of the most eminent modem naturalists, it was Boyle who opened up those chemical inquiries, which went on accumulating until, a century later, they supplied the means by which Lavoisier and his contemporaries fixed the real basis of chemistry, and enabled it for the first time to take its proper stand among those sciences that deal with the external world.
(Systems science) does not aim to ?nd the one true representation for a given type of systems (e.g. physical, chemical or biological systems), but to formulate general principles about how different representations of different systems can be constructed so as to be effective in problem-solving.
