Sir Isaac Newton (1643-1727) was one of the greatest minds of all time. He was an astronomer, a mathematician, an alchemist, and a physicist. He created many laws that are still used today. Sir Isaac Newton taught the world many things about how the universe works. Isaac was born in 1643 in Lincolnshire, England. As a young boy, Isaac went to a school called The Kings. Then he studied at Trinity College in Cambridge. Here, he developed something we know today as “calculus.” Calculus is defined as “the study of how things change,” and is a mathematical process. Newton was involved in the study of optics – he showed how a prism can reflect light and change white light into multicoloured light. He showed how a second prism and lens could change that coloured light back into white light. This important discovery led him to the creation of a refracting telescope, which is now known as a “Newtonian telescope.” Perhaps the most important of all though, were Newton’s laws. He had discovered three laws. Here they are: 1. Unless something is pushed or pulled, it will continue moving along a straight line or stay motionless. This is called inertia. 2. Pushing or pulling something affects how it will react. 3. If something is pushed or pulled, it will push or pull in the opposite way. When Newton wrote these laws, he developed the theory of gravity. Using an apple, he made up an equation for what would happened when he dropped it. He then applied this same principle to the universe: particularly, that the same equation he used for the apple, is also applied to the Moon, and to the Earth. He proved that the planets in our solar system are held in place by gravity. Newton held the position of Chair of Mathematics at Cambridge for 33 years.

Once Albert Einstein gave a lecture at the University of Zurich. Students presented at his lecture occupied 5/7 of all the seats. There were 540 people present. How many seats were there in the auditorium?
- A.
350
- B.
756
- C.
400
- D.
596
Correct Answer
B. 756Explanation
If 5/7 of the seats were occupied by the students, then the remaining 2/7 of the seats were empty. We can set up a proportion to find the total number of seats in the auditorium. Let x represent the total number of seats. We can write the equation 5/7 = 540/x. Cross multiplying, we get 5x = 3780. Dividing both sides by 5, we find that x = 756. Therefore, there were 756 seats in the auditorium.Rate this question:

Is it true that gravity helps the Earth to stay in orbit around the Sun?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Gravity is the force of attraction between two objects with mass. In the case of the Earth and the Sun, gravity is what keeps the Earth in orbit around the Sun. The gravitational pull of the Sun keeps the Earth moving in a curved path, preventing it from flying off into space. Without gravity, the Earth would not be able to maintain its orbit around the Sun. Therefore, it is true that gravity helps the Earth to stay in orbit around the Sun.Rate this question:
