The word spectrum in this context refers to a range of radio-waves that are used for communication purposes. This includes the FM or AM radio broadcasts that you listen to on the way to work, and even other wireless forms of communication like Bluetooth and Wi-Fi. The smartphone you’re using also uses these same radio waves to transmit data, and… Read more →
Grounding and earthing are similar terms. Still, these are having many differences. GROUNDING Grounding means connecting the live part (it means the part which carries current under normal condition) to the earth for example neutral of power transformer. Grounding is done for the protections of power system equipment and to provide an effective return path from the machine to the… Read more →
Human teeth are almost as hard as rocks! Pain travels through the body at 350 feet per second! A giraffe can clean its ears with its 21-inch tongue! Emus and kangaroos cannot walk backwards. When you walk down a steep hill, the pressure on your knees is equal to three times your body weight. Your skin is actually an organ.… Read more →
More than half of the oxygen you breathe comes from marine photosynthesisers, like phytoplankton and seaweed. In 2001, Pizza Hut became the first company in the world to deliver its food to outer space, they paid a million dollars to send a salami pizza to the International Space Station (ISS). Beekeepers wear white beekeeping suits because white is the least… Read more →
Termites eat wood twice as fast when listening to heavy metal music. A B-25 bomber aeroplane crashed into the 79th floor of the Empire State Building on July 28, 1945. Technically speaking, crystal glass is actually a Liquid that flows very slowly. The WD in WD-40 stands for Water Displacer. The volume of the Earth’s moon is the same as… Read more →
A wine that has a musty smell, similar to wet cardboard or mold, may mean that the bottle is “corked” (the bottle has a contaminated cork. Muscles absorb alcohol faster than fat. As a result, people who have more muscles and less body fat have higher alcohol tolerance. The coldest temperature ever measured on Earth was -89 Celsius (-129 Fahrenheit)… Read more →
Los Angeles is the first major city in the world to synchronize all its traffic lights. Nearly 4,400 lights across 469 miles receive real-time updates about traffic flow to make second-by-second adjustments. The system limits congestion by up to 16% while also dramatically reducing idling time. Norway hires sherpas from Nepal to build paths in the Norwegian mountains. They have… Read more →
Paper is made out of wood pulp which contains cellulose. Another organic substance binding the cells, fibers and vessels that constitute wood, is LIGNIN. Apparently, it is the most abundant renewable carbon source after cellulose. Cellulose, a colourless substance, is remarkably good at reflecting light, which means we see it as being white. To make a fine white paper (Bond… Read more →
As the coronavirus pandemic progressed and patients struggled to breathe, hospitals across the world learned that very sick patients were able to breathe better when they were flipped onto their stomachs. ‘Proning’ is a medically accepted position to improve breathing comfort and oxygenation in COVID-19 patients. This positioning, called proning (or prone-positioning), has been used for decades to improve clinical outcomes… Read more →
Montseras have developed holes because of the lighting conditions they naturally live in. Monsteras grow from the forest floor, vining up to capture the light that enters through the overhead canopy. The only way plants can survive in such environments is by catching as much of the small rays of sunlight that make their way through the canopy. The holes… Read more →
