Who discovered magnetism?

 Magnetism was thought to be used by the ancient Greeks. But many other scientists had experimented and discovered more about it. Investigations about Earth’s magnetism were conducted by German Carl Friedrich Gauss. Electricity is usually related to magnetism, which was discovered by Andre Marie Ampere. But who had discovered it before these scientists? An Englishman from the 1540s had investigated magnetism thoroughly. William Gilbert had discovered way more than other philosophers.  Gilbert was born in Colchester, Essex. He spent most of his years practicing as a doctor.  He was involved with medicine in the navy, which had sparked his interest in magnetism. His free time was full of studying magnetism. He had discovered that earth had two magnetic poles, and therefore earth was just a big magnet. 

In 1600, Gilbert published his book De Magnete. This books full English title is On the Magnet and Magnetic Bodies, and on the Great Magnet the Earth. This book had shocked many people, thinking they knew how a compass worked. The first paragraph of his book it states “…in the investigation of hidden causes, stronger reasons are obtained from sure experiments and demonstrations than from probable conjectures and the opinions of common philosophers.” He wanted the readers to know his experiments are accurate, not like some of the other philosophers and scientists.

Gilbert had created a model of magnetic earth. He had made it out of lodestone, now known as magnetite. He would place magnetic needles near the surface, and the result was exactly like a compass. The north magnetic pole was where the magnetic needle always pointed, and we still follow the same rules today. Therefore he determined the earth interior must be magnetic. 

 New discoveries have been experimented by many scientists and new technologies are being made. From discovering new kinds of magnets to turning heat into electricity with the help of magnetism. Using these experiments, fossil fuels can be eliminated and pollution can be decreased. Magnetism had such a big impact in 1600, and hopefully, it can have the same effect now.

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...
