Sir Isaac Newton Combined the finding and ideas of Kepler, Galileo, and copernicus and came up with the theory that all objects are affected by a force called gravity.

Among these people were Copernicus who believed the sun was at the center of the world and the earth, stars and planets revolved around it. Danish astronomer Brahe helped contribute to this idea by contributing a large mass of data about the universe that he was able to discover. His student Kepler kept his ideas going, as he formulated many laws of planetary motion. He said the orbits around the sun were elliptical, planets don’t move in a uniform speed and the time a planet completes its orbit is related to its distance from the sun. Meanwhile, Florentine Galileo decided to use experiments to find out what happened and not what should happen, and discovered that a uniform force makes a uniform acceleration as well as inertia laws, that an object will be in motion forever unless stopped by another force.

  The understanding of the structure of atoms has changed throughout history. The first documented case of the discovery of atoms dates back to 450 B.C with two Greek philosophers, Leucippus and Democritus (Doc. 1). This was only a theory; however, they proposed the idea that all matter is made up of atoms.

They were important because from then and today people need to use it to do science and other daily stuff that they need to do. He also was very important to the world because if people didn't know the three laws of motion today we basically wouldn't be able to do science because that is how important he was he mad basically science because he was so smart.

Furthermore, his discovery was important because it's been the three laws of motion which also formed the basis of modern physic. The discovery, he made also led to a more powerful way to solving mathematics.

He stated that this was a mysterious force but never continued his research on it. Then in 460 B.C. there was a philosopher named Democritus. Democritus and his mentor Leocippus posed the question that if he broke bread into multiple pieces how many would breaks would it take until there was no more bread. He then was able to make a few theories being all matter was created of atoms and atoms are solid but not invisible. However, there was a man named Aristotle and many other philosophers who disagreed with Democritus and said matter was composed of four main elements. Earth, fire, air, and water. For example, a liquid was made of water and a stone was made of rock. Therefore, Democritus’s theory “ was rejected by Aristotle, one of the most influential philosophers of Ancient Greece; and the atomic theory was ignored for nearly 2,000 years.”(

In 1808, John Dalton published his theory that all materials were made up of atoms and that atoms can bond together in different combinations. After experimenting with his theory and proving it was indeed true alchemist, chemist and scientist were all on the hunt to find new atoms and this started a scientific revolution. With the inventions of better technology and the scientific innovation scientists were able to find many different atoms. Afterward chemist worked harder to determine whether these substance were elements. These scientist soon identified many groups to elements. A Russian chemist, Dimitri Mendeleev organized and formed the periodic table based on all of the information he had collected. Although Mendeleev did not have all

Astronomy. Gravity. Physics. The scientific ideas and theories which are applied to today’s world originated from a highly educated individual known as Sir Isaac Newton. Newton discovered the law of gravitation and how particles attract other particles in the universe.

In agreement with the claim, I assume the discovering of atom and its nuclear and subatomic stuff. If Bohr didn’t think about what is the atom context, not him nor the latest scientists couldn’t explain about the atomic structure. As a matter of fact, his explanation and assumption makes the atom’s inside comprehensible to that era’s scientists, but it lead the later physicists to think about it more and get this issue under analyze more to know about its real complication and find about it.

Franklin realized that if a piece of silk were rubbed against a glass, the glass would have a positive charge. Other scientists at that time believed that rubbing produced electricity, however Franklin said that it was just the "electric fluid" being transferred from the silk to the glass. This is known today as the law of conservation of change and it is one of the basic principles of physics.

The Discovery of the Atom first came from the Greeks which made a theory “The idea that all matter is made up of tiny, indivisible particles, or atoms, is believed to have originated with the Greek philosopher Leucippus of Miletus and his student Democritus of Abdera in the 5th century B.C. (The word atom comes from the Greek word atomos, which means “indivisible.”)” (InfoPlease Atomic theory)

Farnsworth (T.V). The design, construction and manufacturing of useful devices and systems began with the implementation of Michael Faraday’s Law, one of the fundamental laws in electrical engineering, that states that the voltage in a circuit is proportional to the rate of change in the magnetic field through the circuit (www.livescience.com “What is Electrical Engineering?” by Jim Lucas)

Dalton was the son of a Quaker weaver. When only 12 he took charge of

Light, a concept that has been worked with for many years dating back to 500 B.C. Pythagoras hypothesized that humans perceive light due to the human eyes ability to emit rays upon the environment and the emittance gives a human his or her sight (Sekuler). Afterward, human intellectuals started making it more concise to present day knowledge of light. This development of light came from two intellectuals named Christian Huygens and Isaac Newton. Newton exclaimed during the 1700s that light was a stream of particles carrying energy but Huygens, Newton’s contemporary, thought that light needed this invisible “ether” in order for these streams to make light travel. Then, a couple hundred years later, modern scientists such as Albert Einstein, Thomas Young, and Augustin Fresnel proved Isaac’s and Huygens’ hypotheses of light (Rossing, 23-24). This is how the basis of light was created.
