What is MSG, is it actually bad for you?

Monosodium glutamate MSG is a flavor enhancer that is commonly used in restaurant dishes, canned vegetables, soups, deli meats, and other foods. MSG has been designated as a generally recognized as safe food additive by the US Food and Drug Administration (FDA). However, its application is still up for discussion. As a result, the FDA requires MSG to be stated on the label when it is added to food. For many years, MSG has been utilized as a food ingredient. During this time, the FDA has received numerous reports of alarming reactions that have been linked to MSG-containing foods. The MSG symptom complex includes the following reactions: Headache Flushing Sweating Face pressure or tightness Lack of feeling (numbness), tingling or burning in the face, neck and other areas Quick, fluttering heartbeats Chest pain Feeling sick (nausea) Weakness However, no conclusive evidence of a relationship between MSG and these symptoms has been discovered by experts. However, researchers acknowledge th

Airbags; how do they work?

Even if the driver secured properly, an accident would occur at high speeds if there was no airbag. It is a significant engineering challenge to bring the human body to a stop from a high speed in less than 100 milliseconds without causing significant bodily harm. Let's have a better grasp of this life-saving technology by looking at the mechanism of airbag inflation, which is triggered by chemical explosions. Seatbelts are meant to keep the human body from moving, but they can cause internal organ injury if they apply too much stress on the chest area during an accident. Modern seat belts use a torsion bar to slightly release the seat belt in the event of a large impact on the chest. This action causes the upper body to move forward somewhat, but as the torsion bar is released, the upper body's movement is stopped. Working Mechanism of Airbags, Image credit; whyflies.org Please notice that the sear belt only arrests the motion of your upper body, omitting your neck and head, w

Did you know the science behind working mechanism of solar panels?

A earth intercept a lot of solar power (173 thousands terawatts). That's ten thousand times more power than the planet's populations uses. So, is it possible that one day the world could be completely reliant on solar energy?  To answer that question, we first need to examine how solar panels convert solar energy to electrical energy. Solar panels are made up of smaller units called solar cells. The most common solar cells are made from silicon, a semiconductor that is second most abundant element on Earth. Crystalline silicon is placed between conductive layers of a solar cell. Four strong connections connect each silicon atom to its neighbors. This holds the electrons in place, preventing current flow.  Here's the key, a silicon solar cell uses two different layers of silicon. Working mechanism of solar panels, Image credits: acs.org N-type silicon has extra electrons, while p-type silicon has extra electron gaps, known as holes.  When two types of silicon meet at a p/n j
