Blue Light Emitted from Digital Devices May Accelerate Blindness

What you have decided to read on this week's blog post is exposing you to blue light. Blue light is categorized in the middle of harmful light and visible light. The harmful portion of blue light is UV light. While the beneficial part of light is visible light. This light all comes from electromagnetic particles that travel in waves. The only part of the spectrum that is sensitive to the human eye is visible light. Studies say that blue light has a short wavelength which results in a higher amount of energy. Blue light can have a negative and positive impact on your body. 
Believe it or not, blue light does have some healthy effects on your body. One of these effects is boosting alertness. It is also helpful to us humans because it increases our overall feeling of well-being. It gives you feelings of calmness or serenity. The last positive major impact that blue light can have on you is sleep. This is because part of the brain called the pineal gland secretes the hormone melatonin which signals to the brain to get tiered and go to sleep. Blue light has many pros but also has its cons. 
Can you believe that something can be good for you but at the same time bad. Blue light can be categorized with that statement. One of most obvious harmful effects of blue light is digital eyestrain. Some of the symptoms can affect work and learning productivity. Another harmful aspect of blue light is the UV light. It can cause major damage to the retina of your eye. Blue light doesn’t always have a positive effect on your health. 
I have a feeling that scientist will try to further investigate on how to use a different source of light. I also have a feeling that in the future there will be many more ways to reduce the blue light. This could occur in settings like it already does now but with more technology advancement. I also have a feeling that they will have an advanced screen protector to limit blue light  emission.  The last advancement I could see future scientist doing to protect our eyes is eye drops. These eye drops would offer another protective layer similar to the screen protector. In conclusion this harmful blue light can be avoided in the future with advancements.

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...
