Muscles. We have over 600 of them. They make up between 1/3 and 1/2 of our body weight, and along with connective tissue, they bind us together, hold us up,and help us move. And whether or not bodybuilding is your hobby, muscles need your constant attention because the way you treat them on a daily basis determines whether they will wither or grow. Say you're standing in front of a door,ready to pull it open. Your brain and muscles are perfectly poised to help you achieve this goal. First, your brain sends a signal to motor neurons inside your arm. When they receive this message,they fire, causing muscles to contract and relax, which pull on the bones in your armand generate the needed movement. The bigger the challenge becomes,the bigger the brain's signal grows, and the more motor units it rallies to help you achieve your task. But what if the door is made of solid iron? At this point, your arm muscles alone won't be able to generate enough tension to pull it open, so y...

1)Bermuda triangle ÷

The Bermuda Triangle,also known as the Devil's Triangle, is located in the North Atlantic Ocean.


The Bermuda triangle comes in between Florida, Bermuda and Puerto rico. And all these 3 places form a triangle shape on the ocean.


It is called the Devil's Triangle because whenever any ship or aeroplane comes nearer to the Bermuda triangle it mysteriously disappears, no one knows what happened to those ships and aeroplanes.


There are many unknown questions about Bermuda triangle like

What happens with those ships and aeroplanes ?

What happens with the people?

Etc

            

      And also some people says it's due to the gravitational pull on the earth, which makes the ships and aeroplane disappeared.




2)Mariana Trench÷

Mariana Trench is the deepest part of the ocean and also the deepest location on Earth. It is 11,034 meters deep.


 And Mount Everest can easily fit in it because Mount Everest's height is 8,849 meters.


There are some chances of mysterious creatures that can be found in Mariana trench like Megalodon. Megalodon is an extinct species of sharks.


The environment and the creatures of Mariana trench are totally different because there is no sunlight and the water pressure at Mariana point is very high.


On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard. They became the first people to dive 11km to the bottom of the Mariana Trench. Normal machines cannot go to Mariana trench so they made one machine, because normally machines cannot handle that much high pressure.

Facts about Megalodon ?

About 8 million years ago, a little baleen whale was swimming in the warm coastal waters of Peru. It was only about 3 or 4 meters long, about the size of a Beluga whale, and while it filtered mouthfuls of plankton-rich water, it was unaware that just below it swam a predator. Like the great white sharks of our times,this predator likely hunted whales from below or behind, in case its prey was capable of echolocation.  It turns out that this little whale, known as Piscobalaena, didn’t have that ability, but for the hunter, the element of surprise was enough. It swam up for the attack, and that was thatfor Piscobalaena. We know who the predator was, because it lefta tooth in the whale’s body, which eventually fossilized. It usually goes by its species name, Megalodon,and it was the largest shark that ever lived. At up to 18 meters, it was almost three-quarters the size of a modern Blue whale. Its teeth were as big as your hand – or bigger. And its jaws were wide enough to...

What is the Science behind Human brain ?

Image
The brains consist of three parts.The forebrain, which controls all thoughts, senses, motor functions, emotions and hunger. The midbrain controls auditory and visual reflexes as well as awareness. The hindbrain controls coordination and analysis of senses. Brains have a similar texture to tofu. There are 100,000 miles of blood vessels within the brain. Enough to circle earth four times. The ancient Egyptians believed the brain's function was to produce snot. Though the brain only makes up 2% of the body's weight, it uses 20% of the body's energy. A person’s brain has 100 billion neurons.These cells are known as the gray matter which process information. Einstein’s brains have been preserved for study. It is split into 240 separate slides for viewing. 89.06 is the percentage of people who report normally writing with their right hand, 10.6% with their left and0.34% with either hand. More electrical impulses are generated in one day by a single human brai...
