Facebook

Facebook is the world's most popular social networking page. Its popularity spread like wildfire when mark Zuckerberg along with his classmates Eduardo Saverin, Dustin Moskovitz, and Chris Hughes set up Facebook.          It was launched in 2004 as 'The Facebook' and the access was restricted to Harvard students. The website allowed students to rate the photographs of other students. Students who signed up for the service could post photographs themselves and personal information about their lives. It's popularity increased; within 24 hours, 1,200 Harvard students signed up, and in a month's time, over half of the undergraduate population had a profile. The network soon extended to other universities and high schools in the US and later to the UK. In 2005, it was renamed as Facebook and a year later, it went beyond educational institutions. Anybody who was thirteen years of age with a registered email could create an account on Facebook.    

The story of Walt Disney

Imagine your childhood without the fun loving, adventurous Mickey mouse, donald duck, snow white, repunzel, and Cinderella. Have you ever thought who made these characters. It comes from the brain behind the Walt Disney Company.          Walt Disney arrived in California in the summer of 1923, hoping to make money. He had made a cartoon about a little girl named Alice.  A distributor in New York, agreed to distribute the Alice comedies and this was the start of the Walt Disney  Company with Walt and his brother Roy as equal partners.     (Walt Disney and brother Roy.o.disney) Disney continued with Alice comedies for four years, till he introduced a new character named Oswald the Lucky Rabbit. Through the Rabbit conquered children's minds, Walt lost the copyright of the charecter and in order to make up for the loss, he created Mickey Mouse. Sound films came out around the same time and Mickey Mouse became a cartoon star in no time.               

Why am I here?

3.8 billion years ago First sparks of life The air was just a fog of toxic vapours: Carbon monoxide, carbon dioxide, nitrogen, methene, and cyanide.The planet's surface was dotted with tiny islands in a shallow soup of chemicals. 2.5 billion years ago  clearing the air Single-called "cyanobacteria" microbes in the ocean developed the power of "photosynthesis". Later used by plants, this planet transforming process converts sunlight and carbon dioxide into energy, creating oxygen as a product.oxygen an important breathable gas for the evolution of a greater variety of life-forms began to increase in Earth's atmosphere. 1 billion years ago  life levels up The first multicellular life-forms appeared in the oceans. A cell is the basic unit of life; multicelled organisms are made of colonies of cells that specialize in defferent functions. (Your body is made up of trillions of cells)    (Cyanobacteria)

why does chopping onions makes me cry?

Slicing into an onion releases a cloud of chemicals that react to form a burning chemical with a real mouthful of a name:  syn-propanethial-s-oxide. Your eyes unleash reflect tears to hose off the irritants.

Scoville units

A chemist named Wilbur scoville developed a scale to answer this very question in 1912. His system measures that heat factor of chili peppers is multiples of 100 "scoville units", as rated by human tasters with iron toungues! The higher the rating, the hotter pepper. Here's a peppering  of peppers from all parts of the scoville scale spectrum.... Green bell pepper 0 scoville units. Jalapeno pepper 5,000 scoville units Tabasco pepper 50,000 scoville units Habanaga pepper 500,000 scoville units Ghost pepper 1,000,000 scoville units The Ghost pepper is so hot that it will burn your Skin unless you wear gloves. 

Nearest spiral galaxy

 Andromeda, a spiral galaxy like milky way. Astronomers believe it contains as many trillion stars. At 2.5 million light-years away, Andromeda is the farthest thing we can see with the naked eye, but it's getting closer all the time. Someday, the milky  Way and Andromeda galaxies will collide, Sharing their Star dust and spawning new stars. It's doubtful any humans will see this cosmic collation, which won't happen until four billion years in the future

How do I breathe without thinking about it?

It's done by your brain stem, the autopilot for your most important automatic functions: breathing, blood pressure,  and heart rate
