In 2020, Ioannidis et al. reported that half of the Nobel Prizes for science awarded between 1995 and 2017 were clustered in just a few disciplines within their broader fields. Atomic physics , particle physics , cell biology , and neuroscience dominated the two subjects outside chemistry, while molecular chemistry was the chief prize-winning ...
Importance: Most-popular textbook on subject (according to Amazon.com). Lehn coined the term "supermolecule" in '73, developed the concept of supramolecular chemistry in '78, and won the Nobel Prize for his supramolecular chemistry work in ’87.
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
The earliest recorded metal employed by humans seems to be gold, which can be found free or "native". Small amounts of natural gold have been found in Spanish caves used during the late Paleolithic period, around 40,000 BC.
