It turns out all molecular and biological systems have speeds of the atoms move inside them; the fastest possible speeds are determined by their molecular vibrations, and this speed is about a kilometre per second.
Polymeric materials in the form of wood, bone, skin and fibers have been used by man since prehistoric time. Although organic chemistry as a science dates back to the eighteenth century, polymer science on a molecular basis is a development of the twentieth century.
Molecular gastronomy is not bad... but without sound, basic culinary technique, it is useless.
I honestly feel the term 'molecular gastronomy' is mostly misunderstood. It is not a style of cooking. Rather, it is a philosophy which encourages chefs to be more creative.
Our approach to medicine is very 19th-century. We are still in the dark ages. We really need to get to the molecular level so that we are no longer groping about in the dark.
I don't often meet people who want to suffer cardiovascular disease or whatever, and we get those things as a result of the lifelong accumulation of various types of molecular and cellular damage.
Basically, the body does have a vast amount of inbuilt anti-ageing machinery; it's just not 100% comprehensive, so it allows a small number of different types of molecular and cellular damage to happen and accumulate.
