It seems that the rules of chemistry give the easiest way to determine how life arises from matter, what kind of an architecture life owns and how it works as a non-stopping chain reaction. By the aid of rules of chemistry, it is easy to see what kind of basic structures are possible to make from the definite set of elements and how does these structures transform to other ones. Still, the fundamental basics of life lies in physics. Laws of physics go deepest into the essence of everything. Natural sciences as such are quite “block oriented” (by this I don’t mean they are simple sciences!), but with physics one can explain how attractions between these blocks occur, why actually macromolecules, like enzymes, don’t function in too high temperatures and which reactions are favorable in the terms of thermodynamics. Furthermore, by the methods of physics one can reveal the rules how energy is received or transmitted only in the fixed packets of quanta, how that sugar molecule on the tip of your tongue constantly radiates infrared photons when it vibrates etc. Also, the intuitive everyday view of the world may be useful in our everyday life, but what we actually see is the synergy of millions and millions of quantum mechanical atoms and electromagnetic waves. The real nature of the universe is buried under this illusion. One interesting experiment showing this is the famous double slit experiment. Shortly, if you “throw” molecules (relative big building blocks of matter) through a plane which has two or more holes in it, single molecules seem to go through multiple holes at once. The beautiful double slit experiment showed that material can behave like strange waves, in addition to its particle like features. Like said, this doesn’t seem to have any remarkable role in our everyday scope. When studying and building the Nano World, these phenomena do matter however.
