Prove that 2/10=2

Japanese student: Wrong question. 

Pakistani student: Hum toh school hi nahi Gaya. 

American student:
It's strange, how is it possible?

Indian Rajnikant solved it: 

Two / Ten
=wo/en
(T with T cancel)
w = 23rd letter
o = 15th letter
e = 5th letter
n = 14th letter
So,
23+15 / 5+14
= 38 / 19
= 2

Moon melon - Is it real?

This a Moon melon, scientifically knows as asidus . This fruit grows in some parts of Japan .It is known for its weird blue color.  It can switch flavors after you eat it, everything sour will taste sweet, and everything salty will taste bitter and it gives water a strong orange-like taste. I read it from internet only. But some sources said it is a Photoshop effect of red water melon. If anybody know about this please clarify my doubt.

LCD, LED and Plasma TV – What’s the Difference?

As the technology is advancing too rapidly, the extent of opting to choose between LCD, LED and Plasma TVs is too overwhelming.

As you walk into an electronics store searching for a perfect flat screen TV, you are sure to discover a dozen models that all look alike. Even if all the 3 types look similar outwardly, there are several internal differences that make them stand apart.

Why Tibet is known as the roof of the world?

The land of Tibet is the highest plateau in the world. Plateau is flat land, much higher than sea-level, like mountain which have flat land at the top, instead of peak.  It occupies an area of around 1,000 by 2,500 kilometers, and has an average elevation of over 4,500 meters.  It is the highest and biggest plateau, with an area of 2.5 million square kilometers. Because of this large flat area over the sea level Tibet is known as the roof of the world.

History of Onions

Because onions are small and their tissues leave little or no trace, there is no conclusive opinion about the exact location and time of their birth. Many archaeologists, botanists, and food historians believe onions originated in central Asia. Other research suggests onions were first grown in Iran and West Pakistan.

Antioxidants

Antioxidants are substances that may protect our cells against the effects of free radicals. Free radicals are molecules produced when our body breaks down food, or by environmental exposures like tobacco smoke and radiation. Free radicals can damage cells, and may play a role in heart disease, cancer and other diseases.

Oxidation reactions can produce free radicals, which start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves.

Maida Vs Wheat

Maida is made from wheat. When you grind wheat grains in a mill you obtain wheat flour and when the wheat flour is pressed through a very fine sieve you obtain Maida. Maida is refined wheat flour. Wheat flour has the goodness of bran and fiber and therefore healthy. Maida is very refined wheat flour with all the bran removed and is pure carb.

Why does a ship made of iron float while a piece of iron of same mass sink in water?

It’s because an iron ship is not completely solid. It has full of air filled in it. So the average density of the ship as a whole is less than the density of water. Therefore immersed portion of the ship displaces water equal to its weight. So the ship floats whereas a sheet of iron is compact and there are no air spaces inside it. Iron is denser than that of water. The weight of the sheet is greater than the weight of the water displaced by the sheet. So it sinks.

Which pole is colder, the North or the South?

Both Polar Regions of the earth are cold, primarily because they receive far less solar radiation than the tropics and mid-latitudes do. At either pole the sun never rises more than 23.5 degrees above the horizon and both locations experience six months of continuous darkness. Moreover, most of the sunlight that does shine on the Polar Regions is reflected by the bright white surface.

The South Pole the average temperature is about 56 degrees below zero degrees Fahrenheit (−49 degrees Celsius). At the North Pole the average temperature is a relatively balmy 20 degrees below zero (−29 degrees Celsius).

Why is the Ocean Salty?

All water, even rain water, contains dissolved chemicals which scientists call "salts." But not all water tastes salty. Salt doesn't evaporate when water evaporates. The rain flows back down to the sea, adding a little bit of salt to it constantly. Over millions of years, this makes the sea salty.

Everyone should eat more vegetables

Dear friends our Mom always said to eat more vegetables. But we never think why she is saying about this daily?  Today I am going to express my views about the Health benefits of vegetables.

Contain good amounts of vitamins and minerals.

How do people breathe in and out?

          We usually don’t have to think much about our breathing because our brain controls it automatically. When you have a lot of carbon dioxide the waste gas produced by body processes in our blood, our brain gets the message and tells our lungs to exhale and get rid of it. This action then causes us to inhale, drawing in air that eventually delivers oxygen to every cell in our body. This carefully regulated exhaling and inhaling takes place about 10 to 14 times each minute when we are breathing calmly.

What is AIDS?

AIDS stands for: Acquired Immune Deficiency Syndrome

AIDS is a medical condition. A person is diagnosed with AIDS when their immune system is too weak to fight off infections.Since AIDS was first identified in the early 1980s, an unprecedented number of people have been affected by the global AIDS epidemic. Today, there are an estimated 33.3 million people living with HIV and AIDS worldwide.

Why Is the Sky Blue?

Why Is the Sky Blue?

 The sun emits light that travels through space toward Earth because space is a vacuum. The light remains largely undisturbed until it nears the Earth, whose atmosphere is made up of a mixture of gas molecules (mainly oxygen and nitrogen) and other materials. The closer you get to the Earth, the thicker the atmosphere. Light from the sun appears white but is in fact a combination of colors, and the range of these colors that are visible to the human eye from red to violet, by way of orange, yellow, green, blue and indigo is shown when light is passed through a prism These different colors have different wavelengths and energies, with violet having the shortest wavelength and highest energy and red having the longest wavelength and lowest energy.

What is spectrum?

The electromagnetic spectrum is a vast band of energy frequencies extending from radio waves to gamma waves. When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves. It is represented by frequency (in Hertz) or Wave length (in meter).
