The North Star stays put in one place because the Earth is round.
The ancient Greeks , especially Aristotle, knew this and were the first to state this. Nowadays we say Copernicus discovered the earth was round, for example, but the Greeks had that figured out almost two thousand years earlier!
How Did They Know it?
Greeks had many different arguments for why the earth is round.
One of the best arguments came from Aristotle, who wrote a book called On the Heavens back in 340 B.C. The Greeks were a sea-faring culture, and sailed all over the Mediterranean. And they had noticed, Aristotle tells us, that the north star isn’t always in the same spot overhead.
The North Star
Now remember that all the stars seem to move in a big circle over our heads because the earth itself is spinning. The north star is the center of the circle, and stays put.
However, Aristotle noticed that when you are down south in Egypt, the north star is close to the horizon. When you are up north in Greece again, it’s high in the sky.
How Is That Possible, Since The North Star Is Supposed To Stay Put?
It’s possible, Aristotle concluded, only because the earth is round.
When you are standing at the north pole, where is the north star? Directly overhead. Now place yourself at the equator. Where is the north star? Yep–it’s down on the horizon, because you are now traveling along a curve. Go even farther south and you will not be able to see it at all; the earth will hide the north star. Go farther north and it seems to rise higher and higher and the star will just be a small dot.
Coprenicus
Commonly known by his Latin name, Nicholas Copernicus, was falsely regarded as “The Father of Astronomy” – it should have been Aristotle. Nicholas Copernicus, born February 19, 1473, was the first astronomer to formulate a scientifically based heliocentric cosmology that displaced the Earth from the center of the universe. While a student at the University of Kraków, he discovered several logical contradictions in the existing astronomical system taught at that time, which put the earth at the center of the universe. Later when studying medicine and religious law at Bologna University, Coprenicus pursued further investigations of the movements of celestial bodies, especially the moon. His direct observations, coupled with his studies based on various Greek and Latin astronomical writings, prompted him to originate the Copernican system of the structure of the universe. This theory placed the sun at the center of the solar system and the earth in orbit around it. Kopernik’s most famous written work, De Revolutionibus, which laid the foundation for modern astronomy, was completed in 1530, after fifteen years of painstaking observations and calculations, often with instruments of the astronomer’s own making. Although deeply convinced of the truth of his heliocentric system, Kopernik did not actively seek to publish this work because of its controversial nature. He did, however, manage to catch a dimmed glance at the first printed copy moments before his death on May 24, 1543.
Galileo and Bruno
Two other Italian scientists of the time, Galileo and Bruno, embraced the Copernican theory unreservedly and as a result suffered much personal injury at the hands of the powerful church inquisitors. Giordano Bruno had the audacity to even go beyond Copernicus, and, dared to suggest, that space was boundless and that the sun was and its planets were but one of any number of similar systems: Why! — there even might be other inhabited worlds with rational beings equal or possibly superior to ourselves. For such blasphemy, Bruno was tried before the Inquisition, condemned and burned at the stake in 1600. Galileo was brought forward in 1633, and, there, in front of his “betters,” he was, under the threat of torture and death, forced to his knees to renounce all belief in Copernican theories, and was thereafter sentenced to imprisonment for the remainder of his days.
The most important aspect of Copernicus’ work is that it forever changed the place of man in the cosmos; no longer could man legitimately think his significance greater than his fellow creatures; with Copernicus’ work, man could now take his place among that which exists all about him, and not of necessity take that premier position which had been assigned immodestly to him by the theologians.
“Of all discoveries and opinions, none may have exerted a greater effect on the human spirit than the doctrine of Copernicus. The world had scarcely become known as round and complete in itself when it was asked to waive the tremendous privilege of being the center of the universe. Never, perhaps, was a greater demand made on mankind – for by this admission so many things vanished in mist and smoke! What became of our Eden, our world of innocence, piety and poetry; the testimony of the senses; the conviction of a poetic – religious faith? No wonder his contemporaries did not wish to let all this go and offered every possible resistance to a doctrine which in its converts authorized and demanded a freedom of view and greatness of thought so far unknown, indeed not even dreamed of.” [Goethe.]
Aristotle is well known as the greatest philosopher of his time. He had wide knowledge regarding different disciplines something that has been managed only by a few scientists. His contribution ranges from physics, zoology, biology, politics, ethics and logic amongst others. Contributions made by Aristotle can still be felt in the present age despite having lived hundreds of years ago. It was because of him that we now understand science and matter applicably.
Probably considered as one of the greatest scientist of his time. Just like Aristotle, Isaac Newton was well versed in different subject areas such as mathematics, physics and natural philosophy amongst others. Isaac Newton is best known for his contribution in attempting and managing to explain gravitational law as well as the three laws of motion. High school math and science courses still use his cradle to explain motions and movements.
Up-to-date, Galileo Galilei is still considered as having made the greatest contribution to science. He continued to make discoveries that are still being used in the present age, despite being persecuted by the church for what he believed in. Not only was he a physicist but also an astronomer as well as a philosopher. His contributions to science include creation of telescope and first two laws of motions. It was only in the early 2000s that Pope John Paul II recognized Galilei’s work as legit, after approximately 400 years of denial by the Roman Catholic Church.
Looking at the past of Albert Einstein nobody would not have thought that a boy who could not talk till he attained the age of three and had to wait till he was eight years of age to read could be one of the greatest scientists of all time. In spite of all the hurdles that faced him, he managed to win noble peace prize for the contributions he made in physics.

Nothing in the previous life of this great man of science suggested that he would be one of the celebrated scientists but managed to overcome all the barriers before him to excel.
Up-to-date, Galileo Galilei is still considered as having made the greatest contribution to science. Despite having been persecuted by the church for what he believed in, that did not deter him from making discoveries that are still being used in the present age. Not only was he a physicist but also an astronomer as well as a philosopher. His contributions to science include creation of telescope and first two laws of motion.
Coming in at number four is Charles Darwin even though there are those who dispute to him having been a scientist in the first place. His contributions major on origin of man. He is also known to have traveled extensively around the world so as to prove his theories.
Looking at the past of Albert Einstein nobody would not have thought that a boy who could not talk till he attained the age of three and had to wait till he was eight years of age to read could be one of the greatest scientists of all time.

This device was invented by Volney Mathison, who was collaborating with Hubbard in his experiments. Hubbard claims that the device is capable of measuring whether vegetables and fruits feel pain or not. He tested it on tomatoes and claimed that the tomatoes “screamed when sliced’. The original use of this device is restricted by the Church of Scientology for professionals. It is based as a religious practice by trying to gain knowledge of spiritual freedom of a soul. This device neither fulfills any religious claims properly not does it gives any use to the vegetable experiment that was claimed by Hubbard. Leaving the spiritual artifact side alone, it also lacks proper reasoning for its methods of practice and results, which are controversial. The lack of proper structure and explanation has already made its practice restricted scientifically.
Now, this is funnier than you can imagine. What is a sauna experience if you carry it around anywhere and everywhere with you? Is it making you feel great. Well, the truth is it isn’t any good as real sauna. Besides its funny structure narrows all your scope to relax while you are having one. If you can afford something that might be of no use any further, but looks like a luxury, this portable sauna is just the thing. It was criticized for its model, shape, quality and even its idea in its time.
These Baby Cages were available in London to Chelsea Baby Club members to facilitate them to hang the baby in the cage outside the window. They didn’t have any gardens or any specific place where they can leave their babies when they cannot be left in the house or the streets. So this was the alternative. It sure didn’t work but it was still imagined that parents would want to hang their children outside of high block window for the baby’s entertainment! With a baby, so sensitive and soft to handle, it is hard to imagine that someone did invent this baby cage as a useful thing.
We have black tires in automobile and technology is devoted in making them more efficient for the weight of the automobile and their torque. However, this invention was entirely different. The automobile had Illuminated Tires, not one but all four of them! It was still a limelight for its degree of entertainment. Otherwise, it was completely useless for any automobile.
Now we all know it is hard to give up smoking, but how far one can go to smoke? This experiment is the best answer. Rainy day cigarette holder was invented by Robert L. Stern to facilitate smoking even when it is raining and ones feels like smoking. However, it was not even adopted by chain smokers. The cigarette holder consists of a device covering the cigarette to protect it from raindrops while one is smoking. It you really wish to try it, you will see it is not very useful for the same purpose either.

It has enabled different people to share information with one another thus facilitating. As technology advances so does the accessibility of internet technology.
We all talk about the sixth sense that women have and this has been brought into reality with the development of the sixth sense. The device enables you to do so many things that are intangibles for instance taking a photograph by creating a frame with your hands.
Considered one of the greatest innovations to have come from MIT, the blind eye has been developed with a purpose to enable those who are blind to have an opportunity to see again.
Coming in at number four is an innovation that you won’t probably be seeing in the market for a while. Nonetheless, scientists working at the University of Maryland have managed to teleport information from one atom to another. Still at infancy it is expected that this will open doorways to the way people live once the final innovation is rolled out.
Gaming seems to be continually evolving with the introduction of XM25 that. Its creation is purely intended for the US military enabling them to approximate target distance by utilizing laser range finder and pinpoints at the exact point where the bullet ought to hit. However, the innovation is still in its infant stages.
They were known for their poaching abilities during the 1800s. These identical twins came from a good family but for some reason, turned to crime related activities. They got each other out of trouble all the time and never went poaching together.
A German man and a Jamaican-English woman gave birth to a pair of twins in 2006. While Alicia’s skin is dark and her hair is black, Jasmin’s skin is fair and her hair is blonde. A Genetic expert explained that this happened because the mother’s genes which determine what the skin color of her babies will be, were mixed.
These twins were considered to be telepathic after several experiments were carried out on them. One such experiment involved Richard plunging his hand into freezing cold water and while his respiration rate changed, so did Damien’s.
Tamara Rabi and Adriana Scott were given up for adoption shortly after they were born. Both adoptive parents kept this secret from them but surprisingly, neither knew that the sisters were growing up only 20 miles away from each other. When they turned 20, mutual friends started figuring it out and made the two meet. Even though they did not grow up together, they had very similar traits and tastes.
These two are also known as the Silent Twins. The twins were inseparable from the time they were born but spoke only to each other in a language that nobody else understood. They did not interact with other children and the situation got so bad, that they had to be separated. However, this only made the problem worse and the two got withdrawn and catatonic. After they got reunited, they came to a decision that one of them had to die. Jennifer took the plunge after which June started speaking and communicating with others.
