Science has nothing to do with any dogma. Science ceases to exist when there is a dogma.
My first scientific paper in 1961 reported an additivity rule for substituent-induced shifts of proton NMR signals in steroid derivatives.
Darwinan evolution is limited to the biological aspect but before that happened the molecules themselves had to evolve to enable this further (biological) evolution.
Supramolecular chemistry, the designed chemistry of the intermolecular bond, is rapidly expanding at the frontiers of molecular science with physical and biological phenomena.
Supramolecular chemistry is the chemistry of the intermolecular bond, covering the structures and functions of the entities formed by association of two or more chemical species.
Molecular chemistry, the chemistry of the covalent bond, is concerned with uncovering and mastering the rules that govern the structures, properties and transformations of molecular species.
I was promoted associate professor in early 1970 and full professor in October of the same year. I spent the two spring semesters of 1972 and 1974 as visiting professor at Harvard University, giving lectures and directing a research project.
Modifying ourselves is a natural process because we are a product of nature and what we do is a product of nature. Therefore, if one day we have three time bigger brain and two hearts instead of one (because one is not enough) then this is all part of nature.
Receptor chemistry, the chemistry of artificial receptor molecules, may be considered a generalized coordination chemistry, not limited to transition metal ions but extending to all types of substrates: cationic, anionic or neutral species of organic, inorganic or biological nature.
I was born on September 30, 1939, in Rosheim, a small medieval city of Alsace in France. My father, Pierre Lehn, then a baker, was very interested in music, played the piano and the organ, and became, later, having given up the bakery, the organist of the city. My mother Marie kept the house and the shop.
In 1998, I set up and directed a research group at the Nanotechnology Institute newly created in the Research Center of Karlsruhe. This allowed to offer to former post-doctoral coworkers the opportunity to develop and to progressively set up independent research activities in nanoscience and nanotechnology.
The pace at which science has progressed has been too fast for human behaviour to adapt to it. As I said we are still apes. A part of our brain is still a paleo-brain and many of the reactions come from our fight or flight instinct. As long as this part of the brain can take over control the rational part of the brain (we will face these problems).
We can look at the way of improving the key biochemical processes like photosynthesis itself. A lot of energy is lost to keep the plant cool. So maybe we can think of building plants which are more resistant to heat. Genetically modified plants can be one answer and we can imagine more efficient plants, call them 'energy plants'. And I believe, contrary to what ecologists think, they can still be beautiful plants.
Think that you are part of a big construction called science and you are not just a chemist but you are scientist. Be modest but proud. Modest because you know you will not be able to solve other problems because your life is too short. But be proud because you are contributing to it. Some people will bring a small stone to the building and some people will bring a big one but nevertheless no one can take that stone away from you.
