Alexander Flemming

-
Alexander Flemming was an English chemist born in 1935. Although he was a chemist his most important discovery was not in that field. He is credited with the discovery of Pennissillian.  He attended Pembroke college located in Cambridge England, where he received a bachelors of art and Ph.D. He also attended Harvard University to further his education.
He then was appointed a professor of bacteriology. During his experiments in this position, he was growing a culture of Staphylococcus aureus bacteria in a petri dish. He then noticed a mold growing on the sample, which impeded with the growth of it, he then named it penicillin. His discovery of the mold eventually lead to antibiotic medicine and was used during world war one.
This discovery lead Alexander Flemming to have the name of St. Mary's Inoculation Department changed to the Wright-Fleming Institute in his dedication.  He also won a Nobel peace prize for physiology or medicine in 1945 with the collaboration with  Ernst Boris Chain and Sir Howard Walter Florey. Additionally, he was knighted, making him Sir Alexander Flemming, for his great discovery.
While he was a chemist, not a biologist, his discovery of penicillin was revolutionary. Alexander Flemming is still known as an influential chemist and not a biologist. In the future pennicillian ill still, have the same purpose as it does today. That being to help cure illness around the world.

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...
