Any number may be multiplied by three. Then put all of the digits of that new number together. Whatever number that equals will always be divisible by three, regardless of the starting number.

Pi, often known as the circumference to diameter ratio of a circle, is an irrational number. This is due to the fact that Pi cannot be expressed as a fraction. Also, whether represented as a decimal, Pi never repeats or stops. Oh, and March 14th, or 3/14, is a declared Pi Day.

Leonardo Fibonacci was a native of Pisa. He lived in the 13th century in Italy and is credited with developing the Fibonacci Sequence, which is currently named after him. Beginning at 0 and 1, this series is formed by adding the total of the two preceding integers in the sequence. The Fibonacci Sequence appears frequently in nature, most notably in rabbit litters. In addition, the American prog metal band Tool's song "Lateralus" is written in time with the Fibonacci Sequence.

Whether you like cats or despise them, you've probably heard the belief that these felines have nine lives. But have you ever pondered where this concept originated? It all derives from their ability to jump and land safely! However, there are a few ideas concerning the number nine, one of which being that 9, once again, is a mystical number and has been worshipped as such throughout the years.

Anyone who has played blackjack understands that the aim is to go as close to 21 as possible without going over. However, the game is said to have originated in Italy as Thirty One, which goes back to the 15th century. The aim is identical (to get as near to 31 as possible), but there are a few differences: all cards numbered 8 through 10 are eliminated from the deck, and face cards are worth one-half their face value.

If you approach someone on the street and ask them what their favourite number is—of all the entire numbers between 1 and 100—nearly 10% will respond "7." These were the results of mathematician Alex Bellos, who asked respondents to choose their favourite number and discovered that "7" was the most frequent answer. It was picked 9.7% of the time.

You'd think that the unlucky number 13 would be avoided by most individuals. However, according to Alex Bellos' study, it was the most popular two-digit number (chosen by 5% of all respondents) and the sixth-most popular number overall (after 7, 3, 8, 4, and 5 in the top five spots—yes, the number five is also the fifth most popular number).

The number 7 may be so popular due of its mathematical uniqueness. Alex Bellos explains once more: "Seven is the most prime of the first ten numbers. It cannot be multiplied or divided inside the group. It has a distinct vibe." For example, you could multiply 4 by 2 to obtain 8, or divide 10 by 2 to get 5, but you can't do anything with 7.

A googol is defined as one followed by one hundred zeroes. A googolplex is composed of a 1 followed by a googol zeroes. If it's difficult to picture how lengthy the number would be, there's a good reason for that: writing it out would result in a number so large that if written out and printed in a volumed series of books, it would weigh more than the whole world.

Apple's initial iPod included a small Easter egg. This game could only be accessible if you knew the correct sequence of buttons to press. "Go to the 'Around' menu and hold down the center button for about three seconds to play a Breakout (Pong) game while you listen." Breakout, the hidden game, is significant in Apple's history since it was a product on which both Steve Jobs and Steve Wozniak collaborated at Atari.

Richard and Maurice McDonald both the company's founders established and occupied a hot dog stand near the Santa Anita racecourse in Arcadia, California, the USA in the late 1930s. They launched a drive-in barbecue restaurant in San Bernardino, California, in 1940, which they converted into a burger establishment in 1948. Maurice and Richard McDonald owned the world's ninth-largest economy, with 27 billion dollars in income from McDonald's franchisees.

The longest novel which exists is ‘In Search of Lost Time’ by Marcel Proust. This masterpiece has made its mark and left its essence in the Gunnies Book of World Records. The whole novel is contained in 13 volumes clocking up nearly 1.3 million words. Isn’t this amazing?

Have you ever heard about Pangram? Pangram in the English Language is a sentence that contains every letter in the language. Sounds interesting? Isn’t it. One of the best examples of Pangram is ‘The quick brown fox jumps over the lazy dog’. The sentence has every letter and hence is a pangram. Can you think of some more Pangrams?

It might come to you as a matter of surprise, but kakapo, the world’s largest parrot, can not fly. Kakapo can grow up to two feet and can weigh up to nine pounds. Kakapo is the only flightless parrot in the world. But that’s not the only interesting fact about the world’s largest parrot. Kakapo is also the only parrot that is active at night.

Every book has its own worth. But the most expensive printed book in the world is the 1640 Bay Psalm book. The book is from America and was sold in 2013, in November, for USD 14.2 million.

In India, there are more vegetarian options and consumables influenced by Indian food on the McDonald's menu. The Veg Pizza McPuff, Maharaja Mac (select veg or chicken), McAloo Tikki (potato patty), McSpicy Paneer (cheese patty), and Masala Grill Veg are some of the distinctive Indian McDonald's options.

Yes! You read that right. Parrots have zygodactyl feet. Parrots' feet are much like human hands that they use to pick up their food and bring it to their mouth. They have one of the strongest feet among all the birds, which they use to clench branches for a long period. The strong feet even allow these birds to hang upside down from the branches.

Have you ever thought about why snakes put out their tongues? They're probably trying to smell their surroundings with their tongue. They have a Jacobson's or vomeronasal organ on the roof of their mouth. The odor then travels from the tongue to an organ in their mouth. Their odor is particularly pleasant and has been characterized as smelling in stereo. They have a long tongue and numerous sensors that can detect varying levels of chemical stimuli.

According to Merriam-Webster, the "octo" prefix alludes to the eight points on the popular sign, but the "thorpe" remains a mystery. One hypothesis derives from the Old English term for "village" because the sign resembles a hamlet surrounded by eight fields!

Snakes are commonly labeled "cold-blooded," although this is false because their blood is not chilly. The correct phrase is ectothermic, which means their body temperature is variable and controlled by external factors. Unlike mammals and birds, Reptiles cannot regulate their body temperature internally and therefore rely on heat sources such as the sun to warm up.

Elephants, the largest land animals, consists of around 150,000 units of muscle units in their trunk. Trunks of the elephants are considered the most sensitive organ found in any mammal. Asian elephants have been found to pick up a peanut, shell it, blow the shell out and eat the nut. Moreover, Elephants use their trunks to suck the water, and a trunk can contain up to 8 liters of water. Isn't this amazing?

While more individuals use English as a second language, Mandarin Chinese is spoken natively by approximately three times as many people. English is studied as a second language by almost two billion people, yet only 350 million speak it natively.

Have you ever thought of a dance move of a bee? If no then you should know that they have a dance move called 'waggle dance.' However, it's not actually a dance move but a way of their communication to tell their nestmates where to go to find the best food source. And this discovery took two years of the researchers at Sussex University to decode this waggle dance.

Have you ever wondered or thought why snakes may make you feel uneasy? They don't even have eyelids! As a result, they cannot blink their eyes, and they sleep with their eyes wide open. To protect their eyes, they have a thin membrane linked to each of them instead of eyelids. The membrane is known as a brille, which translates as spectacles in German.
