A magnet is any object that has a magnetic field. It attracts objects like iron, nickel and steel. Magnets are made artificially in different shapes and sizes depending on their use. For example, the magnet holding a refrigerator shut is far larger than one being used as a car decal and showcasing your recent vacation. 
The magnetic compass needle is commonly used for things like sailing, hiking, driving without a map and other outdoor activities. The compass needle is a very very very small magnet which is free to move horizontally on a pivot. One end of the compass needle points in the North direction and the other end points in the South direction. The end of a freely moving magnet will always point in the North-South direction. The end that points in the North is called the North Pole of the magnet and the end that points South is called the South Pole. It has been proven by experiments that like magnetic poles repel each other whereas unlike poles attract each other.
During China’s Han Dynasty, between 300 and 200 BC, compasses were made but, ironically, they were not used for navigation. They had a much more spiritual use. The early compasses created by the Chinese were used in fortune-telling by geomancy, the interpretation of lines and geographic alinments as symbols of the divine. The navigational compases that emerged from China’s Song Dynasty of the 11th century had a unique design.  There was a spoon that  was placed in the center of a bronze circle and the magnets made it spin around. When it stopped the handle part of the spoon was pointing south and the bowl part of the spoon would point north. These compasses were called ‘South Pointers’. The bronze disc would have cardinal direction points, signs for various constellations and other important symbols and information. 
I do not believe that compases will be used much in the  future because of the iPhone compass feature. Also, the human population has already excavated the majority of the planet. Therefore, there is not a real need to discover much else then where we will inhabit.

Mahar-ullah Shahminah- Molecular Gastronomy

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...
