New discoveries in Magnetism

-
In an effort to understand, measure and control magnetism, at the atomic level, researchers at the National Institute of Standards and Technology (NIST), have been able to find a new method to manipulate the nanoscale properties of magnetic materials. 

 The new method focuses on a quantum mechanical property, called a spin, which has a minuscule magnetic field. The electron spin can point only “up” or “down.” Scientists have been able to find a way to flip the spin, thus the direction of the magnetic field as well. Materials such as cobalt, have neighboring spins’ electrons interact, causing the them to face the same direction. Because of this, some spins are pulled with them, making the spins gradually twist. They’re new discover though, is capable of controlling the direction of that twist, placed in a film of cobalt, only three atomic levels thick.   
 
Another discovery made by scientists was uncovering a hidden electromagnetism feature, now called the “camelback effect.” It is a system of two lines of transverse dipoles. This new discovery serves as a one-dimensional confinement. It is as los called to be a natural magnetic trap. 

 In think that since both sources are dated back to 2017, that something even bigger is currently happening. We found a way to manipulate the  nanoscale proteries is magnetic materials, what is it we can manipulate next? Is it possible that, since opposites attract, that the same sided magnets will finally be able to join together due to new technology? And what does that mean if it does? Advancing our knowledge and technologies is cool, but the real question to it is “how does it help us in the long run?”

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...
