The ways Humans see Color Through Light Waves
Sophie Boris

Humans see color all around us and it would be odd to think of the world without color, a world where rainbows are all just one singular shape and apples aren't green and red but just well colorless. Are eyes have learned to process “color” or light waves that are just simply bouncing off of he object. This might be confusing to think about that the idea of color doesn't really exist color is just the light waves that are reflect from the properties in that certain object. Color is just something that light waves makeup and your brain processes.






When you are looking at an object it may appear like a color but thought process of how you see that color is really the interesting part. In the back of your eye there are cones, there are more in some people's eyes than others but they are all in a small part of the eye. When you look at this object the wavelengths of the object are what determines what color you are going to see. When the light waves reflect off the object and hit your eye this is where one of the most important parts come in the cones. Cones process the light that comes into the retina so once the light is in the eye the cones will determine the information and send that to the optic nerve. From there the optic nerve then sends it to the visual cortex of your brain which will then come up with whatever the color of the object is.


When people can’t see color or are color blind usually one or more of their cone types are not working or not as strongly as someone who can see the whole spectrum of colors. Cones see green, blue, and red these then bounce back information so when one of the cones aren't working you can tell it will have an affect on the slight and how color is transmitted. Though having the red and green cones are most likely to get affected in people and having that form of color blindness.




To me the idea of color not being true but just light waves reflected off of an object really confuses me. I understand how it works and I get why and how we see it but when I look at something I don’t like to think of it. It confusing me more than anything, like color should just be color is it really hard for something to be not a color. That might not make any sense but at the same time this doesn't make to me, this whole concept just really throws me off.

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 ...

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 ...

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...
