Aleksandr butlerov biography of william butler
September 15 is Aleksandr Mikhaylovich Butlerov&#;s birthday. Butlerov was a Russian organic chemist who introduced the term &#;chemical structure&#; to modern chemistry.
Butlerov&#;s chemical structure theory was first to look at the chemical structure.
Aleksandr butlerov biography of william Alexander Mikhaylovich Butlerov (Russian: Алекса́ндр Миха́йлович Бу́тлеров; 15 September – 17 August ) was a Russian chemist, one of the principal creators of the theory of chemical structure (–), the first to incorporate double bonds into structural formulas, the discoverer of hexamine (He believed a molecule&#;s nature is determined by the type and number of atoms and their arrangement and relationship to each other, otherwise known as their chemical structure. He demonstrated the existence of isomers where molecules could have the same molecular formula, but different structures. He also was the first to recognize some organic compounds contain double bonds.
Butlerov was also the first to synthesize formaldehyde.
Formaldehyde (CH2O) is the simplest aldehyde and is used as a basic building block in several organic chemical syntheses. It is also used as a stabilizer in photography and histology and as a biocide to kill bacteria and fungi.
As a schoolboy, he and a couple friends attempted to create their own version of sparkler fireworks.
What they instead created was a large explosion.
Aleksandr butlerov biography of william shakespeare Aleksandr Butlerov (born Sept. 6, , Chistopol, Russia—died Aug. 17, , Butlerovka) was a Russian chemist who helped advance the theory of structure in chemistry, especially with regard to tautomerism, the facile interconvertibility of certain structurally similar compounds.This explosion earned three days of class humiliation where he was forced to sit in a corner during meal times wearing a placard that read &#;The Great Chemist&#;.
Notable Science Events for September 15
&#; William Coblentz died.
Coblentz was an American physicist who contributed greatly to the studies of infrared spectroscopy and radiometry.
He was the first to experimentally verify Planck&#;s law relating radiance frequency and temperature of a blackbody. He also discovered many chemical functional groups absorbed infrared wavelengths. His infrared studies of the planet Mars discovered a large day/night temperature difference which implied a thin atmosphere.
&#; Murray Gell-Mann was born.
Gell-Mann is an American physicist who was awarded the Nobel Prize in Physics for developing the quark model.
Biography of william shakespeare Its creator, the outstanding Russian chemist Alexander Butlerov, was born on September 15, The Kazan Institute of Chemistry is actually named Alexander Butlerov Chemistry Institute. It was in Kazan where young Butlerov took up the interest in chemistry.This model identified the SU(3) flavor symmetry and the concept of the quantum number of &#;strangeness&#;. He coined the term Eightfold Way to describe the theory that organizes subatomic baryons and mesons into octets.
&#; Guillaume-Benjamin-Amand Duchenne died.
Duchenne was a French physiologist who was a pioneer of muscular electrophysiology.
He was the first to describe and treat several muscular and neural disorders. He also introduced biopsy to the diagnose problems in particular tissues. Duchenne was also known for his research into electric shocks to muscles in the face to study human expressions. The Duchenne smile is a genuine smile of happiness that utilizes both mouth and eye muscles.
