Isaac Newton was just seeing the fall of a fruit, which inspired the development of Newton's law of universal gravitation. The scientist's biographer, William Stukeley, noted this in his book Memoirs of Isaac Newton's Life. This is the source of the legend of an apple falling on Newton's head.

We can't completely comprehend the strength of our own vision since even on level terrain, we're constrained by the skyline. The maximum distance at which the experiment is unaffected by Earth's form is just approximately 3.1 miles. In truth, a person can see considerably farther: if the world were flat, we would be able to see a flame at a distance of 27 miles in absolute darkness.

Have you ever heard of sharing the DNA with Gorillas? But yes, we do. We share 98% of our DNA with Gorillas. This means that exposure to human illnesses, even a cold, can negatively impact the Gorillas as they are so much similar to us, genetically. Still, they haven't developed the necessary immunities. Interesting, isn't it?

This unexpected paradox arose due to how scores are calculated: the number of civil infractions and criminal offenses committed in a year should be divided by the municipal population. The number is considerably fewer in Vatican City than in So Paulo, Lagos, or the Bronx. In 2006, for example, the population of Vatican City was 492 people, but the number of crimes reported on its territory was 827. As a result, the statistical crime rate in the country was found to be the highest in the world - 1.68 crimes per inhabitant.

These creatures, renowned for their peaceful lifestyle, like going for a swim. Even though a sloth travels 2 meters per minute on land, it can travel 5 times quicker in the water! Because of their sluggish metabolic rate, animals can go for extended periods without breathing.

Mountain Gorillas live in two isolated groups, one in the Virunga Volcanoes and Bwindi Impenetrable National Park, Uganda. They are basically found in the high-altitude bamboo and montane forests which are surrounded by settlements and agriculture.

Lions prefer hunting at night as they have eyes that are adapted to the dark. And these features give them a great advantage over their prey. Lions also prefer hunting during the storms as the noise and wind make it harder for the prey to hear or see them, and hence they can easily attack them. A great strategy, isn't it?

Lions are very adaptable and hence can live in dry areas such as the Kalahari desert. Here they meet their water requirements from their prey and some plants such as Tsamma melon.

Mosquitoes are cold-blooded insects. They differ from humans in that their body temperatures are modified based on their current location. As a result, mosquitoes, like most other insects, are more noticeable during the warmer months of the year. Mosquitoes that live in temperate climates prefer to hibernate a lot.

Water is vital for mosquitoes because they lay their eggs, which hatch into larvae known as wigglers. These wigglers feed on organic materials in stagnant water and breathe oxygen from the surface. These wigglers eventually mature into pupae that do not feed and are partially enveloped in cocoons. These pupae mature into adult mosquitos after a few days. Before a mosquito can fly, it must go through this process for ten days. Use a mosquito repellent spray or a roll-on insect repellent.

Are you aware that your blood aids mosquito reproduction? Your blood contains the protein needed by mosquito eggs to grow. You should also be aware that only female mosquitoes bite. Apply insect repellent cream or lotion to protect yourself from mosquito bites.

Did you know that there are more types of mosquitos on the earth than there are humans? There are over 3,500 different mosquito species ready to suck your blood. To give you an idea of how big that number is, imagine stacking 100 trillion mosquitos on a football field. The mound would be more than three miles tall.

Mosquitoes are one of the most dangerous animals on the planet, yet their optimal life span may surprise you. The average lifespan is a little less than two months: a male mosquito normally survives for three to five days after mating, whereas a female mosquito can live for a month or two under optimal conditions. Females lay eggs every three weeks at the period.

To begin, you must first determine the location of an earthworm's front end. The saddle or clitellum, a fleshy ring around its middle that sits closer to its head-end, is the best method to determine. The common earthworm may survive having its tail cut off below the saddle because you'll be missing most of its major organs. Still, it'll never be the same again. So, if at all feasible, use caution when holding your lawn spade.

Earthworms are fully formed when they are born, except for their sex organs. Their sexual system takes 60-90 days to develop. An earthworm's lifespan can range from four to eight years. Gardening earthworms, on the other hand, only live for a year or two.

Experts believe that cats hate water because it is bad for them to have wet fur. It also terrifies a cat to lose control of its ability to float.

India is a land of customs and traditions and houses so many spectacular temples too. In the state of Rajasthan, India, there is even a temple of the rats. Pilgrims visit this temple to offer their prayers to the thousands of rats residing there. It is a belief that these rats are the ancestors. Crazy but still a belief.

There are thousands of distinct species all throughout the world, and Britain has 26 of its own. The most prevalent in the UK are reddish-brown 'surface dwellers,' such as tiger worms (Eisenia fetida), grub around in rotting leaves and other organic materials. Then some worms dig no deeper than 30cm, such as the grey worm.

Whale sharks can neither chew nor bite as they are filter feeders. And their mouths can stretch up to 4 feet wide, but their teeth are tiny, and hence they can only eat planktons and small shrimp fishes by using their gills. Sharks can process 6,000 liters of water an hour through their gills. This shows how laborious it is.

Sharks can be found in all the temperate and tropical oceans except the Mediterranean Sea. And the whale sharks used to migrate thousands of miles to different feeding grounds. But they move very slowly, around 3 miles per hour.

Have you ever thought of a post office that is floating? But in this incredible world, we have it too. India has a floating post office in Srinagar. The post office is built on a houseboat and even houses a museum in it. Interesting, isn't it?

Nobody understands why cats meow, but researchers believe they're channeling their inner kitty. Baby cats meow to attract their mother's attention, but as adults, they do not meow when socializing with other cats. According to some experts, felines use the noises they produced as infants with humans to communicate their emotions and physical necessities.

On October 18, 1963, French scientists launched the first cat into space using a rocket. The feline's name was Félicette, and she landed safely after a parachute descent. She'll almost certainly fall on her feet.

Greyhound dogs and cheetahs have bus lines named after them, but house cats are just as fast: the typical running feline can reach speeds of up to 30 mph. In a school zone, that's enough to obtain a ticket.

Cats are genetically programmed to be unable to taste sweets. They will most likely nibble on your platter if it contains meat, but they will ignore it if it includes dessert.
