Is it true that everything weighs less at the equator?

Yes, anything will technically weigh less at the Earth’s equator compared to other parts of the world, say the North or South pole. Any object weighs lighter in the equator, because it is farther from the earth’s center of gravity as compared when it is weighed in the Northern or Southern Poles. You see, the earth is not a perfect sphere and it is “flattened” at the poles because of the rotation of the earth. Thus, the earth’s gravitational pull on an object is greater in the either poles than at the equator.

Furthermore, the acceleration due to the rotation of the earth also affects the weight of an object in the equator. The centrifugal force tend to “throw it off” away from the planet. There is no extreme rotation at the poles so weights of objects are not affected.

How do you escape from a quicksand?

Question: How to escape from a Quicksand?Stumbling into a quicksand seems to be a scary predicament. Thanks to movies and television which gave these sink holes a bad reputation. However, a real quicksand will not suck people all the way in. But getting out in one can be difficult.

Contrary to its depiction in media, a man who is stuck in a quicksand will only sink to his waist, elbows or armpits, depending on how much he weighs and what he is carrying. Objects in a quicksand will sink only to the level at which their weight is equal to the weight of the displaced sand/water mix. In fact, humans will float in quicksands!

Is the brain really the most important organ in the human body?

Question: Is the brain really the most important organ in the human body?In a way, yes. The brain is the most important organ in our body. It sort of serves as the boss of the other organs. It runs the show and tells the other parts what to do so the whole body functions properly.

However, the brain is also dependent on the other organs. For instance, the brain will not work properly without the heart to supply blood and lungs to provide oxygen, etc.  The body may be kept alive, but without the brain, a person can’t truly live. Here are some interesting and weird facts about this big, wrinkly, gray sponge called brain.

Why do we shiver after we urinate?

The tingling sensation down the spine which causes involuntary quivering most of us experience after relieving ourselves is technically called  post-micturition convulsion syndrome or PMCS. The condition is more commonly referred to as “pee shakes” or “piss shivers.”

While there are no scientific research conducted to look into the cause of this phenomenon, there are several theories that try to explain why we shiver when we pee. The most popular notion suggests that we shiver because of rapid loss of warm fluids which lowers the body’s temperature. Shivering is our bodies’ way of warming ourselves back up.

How does the Venus flytrap catch its prey?

Venus flytraps (Dionaea muscipula) are the most popular carnivorous plant. Because of their bizarre appearance and carnivorous nature, they are highly cultivated as a novelty plant.

What’s remarkable about these plants are the traps which are located at the tip of the leaves. They are made up of a pair of terminal lobes hinged at the midrib. The top of the lobes contain red anthocyanin pigments and three hair-like trichomes per lobe. The edges of the lobes are fringed by stiff hair-like protrusions, that form some sort of grill, preventing the prey from escaping when the lobes snap shut.

Why are diamonds so expensive?

Diamonds are actually carbon pieces that was subjected to intense pressure and heat far down in Earth’s interior.  It takes a lot of time before the carbon is compacted and becomes the incredibly hard diamond.

Diamond are known as the hardest known natural substance on Earth. But before they become into the sparkly gems that we are familiar with, they must be first extracted from the earth, cleaned, cut and polished before they even get to the jewelers.
