Google's doodle on this day commemorated the "104th birthday"(is it still a birthday?) of Dorothy Hodgkin. I was happy to find I could recognise the molecule, before reading any further. I'm a real chemist (sounding like Pinocchio)! I particularly liked the Orange oxygen atoms :-)

...a pioneer of the field of X-ray crystallography. A 100 year old
technique in chemistry which has revolutionized the way we understand
the structure of the universe on a molecular level. By studying the
patterns produced by X-rays, scientists are able to surmise the
molecular structure of materials. A technique so important that it has
had a direct role in producing multiple Nobel Laureates including
Dorothy Hodgkin, who was awarded one in 1964 for her work on uncovering
the complex structure of Penicillin G (the model in the doodle).
