5 Famous Astronomers You Should Know…

Portrait Of Copernicus

1:- Nicolus copernicus (1473-1543)

Birth : Thorn, Poland

Copernicus busted the classical Greek theory of astronomy, which said the planets and celestial bodies orbited around the stationary Earth.

He is often called the “father of modern astronomy.”

His skeletal remains were excavated by archeologists in Poland several years ago, and are set to be re-buried under the altar of Frombork Cathedral.



2:- Galileo Galilei (1564-1642)

Birth:  Pisa, Italy

Galileo has also been given a paternal nickname, “the Father of Modern Science.”

Galileo as compare with Archimedes, Newton, and Einstein as one of the greatest scientists of all time. His discoveries, made with the crudest of equipment, were brilliant examples of scientific deduction. Galileo’s studies of natural laws laid the groundwork for the experimental scientists .


3:-Edmund Halley (1656-1742)

Birth:  London, England

Halley is best known for his studies of the comet that bears his name. He observed it in 1682, calculated its orbit, and predicted its reappearance

Halley was  friend of Isaac Newton, and it was at Halley’s urging and expense that Newton’s Principle, that formulated the laws of gravitation, was published. Halley was also an inventor; he built a successful diving bell and found a way to supply divers with compressed air. Diving Halley contributed to other fields as well, including meteorology, optics, magnetism, and mathematics.



4:-Stephen Hawking (1942—

Birth: Oxford, England

Stephen Hawking is probably the most famous physicist of all time after the Albert Einstein.Hawking’s A Brief History of Time: From the Big Bang to Black Holes (1988), which provides an overview of the origin and structure of the universe, was a best-seller.

He became known for his study of certain physical characteristics of black holes, work that led to greater understanding of the origin of the universe.

5:- Sir Isaac Newton (1643-1727)

Birth:  Lincolnshire, England

In Newton’s view, gravitational force was everywhere, from an apple falling from a tree to the moon being kept in orbit by its mutual attraction with Earth.

His three laws of motion — inertia, acceleration, and action and reaction,remain a cornerstone of modern physics. His law of universal gravitation laid forth the theory that all particles in the universe exerted some gravitational force.

Newton’s conception of universal gravitation dominated physics for more than two centuries,before Einstein theory which altered this concept.


The top Ten predators of the world…

1. Great White Shark

This animal is No. 1 for its remarkable predatory abilities.With its streamlined  body and strong jaws, the great white is a   powerful animal: a fast swimmer and  an agile aquatic acrobat able to   leap high out of the water to surprise its  prey. The great white shark   also has multiple rows of sharp serrated teeth,  each being replaced as   soon as one is lost. In fact, a single shark can go  through more than   50,000 teeth in its lifetime



2. Lion

Lions live in social  groups  called prides, and all members  work together in the hunt. Young  lions  learn their place in the pride early in  life by play-fighting,  which  teaches them the skills they’ll need for the hunt  and determines  what  role they are most suited to perform. Lions’ hunting  success rate  is  only about one in five, but those odds are impressive when you  consider  that their prey species are massive creatures with plenty of fighting  power of their own.



3. Grizzly Bear

The grizzly bear, also known as the brown bear, is probably the most feared  animal in North America. This powerful predatory animal can  stand 7 feet tall  and weigh more than 800 pounds. Its strong limbs and  huge  paws can kill a man  in a single swipe, and its powerful crushing  jaws  allow it to feed on a  variety of foods, including large mammalsmain-qimg-ce1df4ed7aba7f5b77ae4e6ccd279740

4. Killer Whale

The name suggests, the killer whale is a deadly predator, combining   remarkable skill with awesome physical power. Orcas have a  number of  ingenious  techniques in their hunting arsenal, giving them  one of the  most diverse diets  of all aquatic predators.



5. Crocodile

There is nothing more frightening than a predator that lurks  underwater for its prey, camouflaged by the surrounding environment,  silently  watching its victim and planning its kill. No. 5 in our  countdown is the  crocodile, a stealthy and extremely violent predator.  With long,  powerful jaws and teeth, the crocodile preys on a variety of  animals.



6. Komodo Dragon

The largest of all lizards, the Komodo dragon is a mighty reptile that weighs up to 300 pounds and can reach a length of more than 10  feet.This animal has multiple predatory  advantages: speed,strength and the tenacity to bring down prey species twice its size.

7. Gray Wolf

Most of the world’s top predators are strict loners, preferring to rely on  their own prowess to bring down prey. But to the gray wolf, the success of the  hunt depends on cooperation among many.main-qimg-7f4500394bf8a3c1cd66f7b400afd179


8. Piranha

Known worldwide for its  aggressive  predatory feeding behavior, the piranha is found throughout the fresh waters  of South America. They typically feed at dawn and dusk, lurking in the water and waiting for a small animal to pass by.



9. Black Mamba

The most fearsome animal in all Africa may well be the black mamba,  the   giant venomous snake found throughout the southeastern portion of  the   continent. It gets its name from the black skin on the inside of  its mouth, which it displays just before it strikes.



10. Tarantula

Tarantula spiders are among the most feared animals on the planet, and  with  good reason. Not only are they giants, as spiders go, but they are  such  stealthy and skilled hunters that no small animal that wanders  within their  grasp stands a chance at survival. The typical hunting  modus operandi for  tarantulas is to be patient.

the Man Who Saved the World…

50 years ago since october 27 1962, at the height of the Cuban Missile Crisis, second-in-command Vasilli Arkhipov of the Soviet submarine B-59 refused to agree with his Captain’s order to launch nuclear torpedos against US warships and setting off what might well have been a terminal superpower nuclear war. 


The US had been dropping depth charges near the submarine in an attempt to force it to surface, unaware it was carrying nuclear arms. The Soviet officers, who had lost radio contact with Moscow, concluded that World War 3 had begun, and 2 of the officers agreed to ‘blast the warships out of the water’. Arkhipov refused to agree – unanimous consent of 3 officers was required – and thanks to him, we are here to talk about it.


Another interesting nugget of information about him –

:- K19 accident : In July 1961, Arkhipov was appointed deputy commander or executive officer of the new Hotel-class ballistic missile submarine K-19. During its nuclear  accident, he backed Captain Nikolai Zateyev  during the potential mutiny. While assisting with engineering work to  deal with the overheating reactor, he was exposed to a harmful level of  radiation.This incident is depicted in the American film K-19, The Widowmaker.

some of the amazing facts…

1:- Panda researchers in China, wear panda costumes to give mother-like feeling to a lonely baby panda who lost her mother.


2:- After needing 13 liters of blood for a surgery  at the age of 13, a man named James Harrison pledged to donate blood  once he turned 18. It was discovered that his blood contained a rare  antigen which cured Rhesus disease. He has donated blood a record 1,000  times and saved 2,000,000 lives.


3:-  If a statue of a person on a horse has both front legs in the air, the person died in battle; if the horse has one front leg in the air, the person died as a result of wounds received in battle; if the horse has all four legs on the ground, the person died of natural causes.


4:-The Ramses brand of condom is named after the great Pharaoh Ramses II, who supposedly fathered over 160 children. 


5:-Each king in a deck of playing cards represents great king from history. Spades – King David, Clubs – Alexander the Great, Hearts – Charlemagne, Diamonds – Julius Caesar.
