Recommended: Einstein the principle of relativity 1920
Albert Einstein, this man is well known by almost everyone on this planet, he is mainly known for his “Theory of relativity” study and the famous equation “E=mc2.” When Einstein was a boy his teacher initially called him slow and lazy, by the age of 15 one of his teachers said that there was nothing left to teach him. In 1905 he published five amazing scientific papers about:
Brownian Movement, or the zigzag movement of tiny particles in suspension, this theory helped to prove the existence of atoms and molecules.
The Mass and Energy Link, This theory is all about how “E” = energy, “m” = mass and “c” = speed of light, therefor; E=mc2. This equation shows how one particle contains massive amounts of energy.
These are just two of the incredible papers done by Albert Einstein. The

other two papers were about the theory of relativity and the quantum theory of light. Isaac Newton, he is best known for his theory of gravity, discoveries of the laws of motion which then became the grounds of physics and his invention of calculus, another form way of calculation in maths.
Isaac was an astronomer, mathematician and scientist who was born on the 4th of January in 1672 and died on the 31st of March in 1727. In 1687 Newton published his most famous work called Philosophiae Naturalis Principia Mathematica which means “Mathematical principles of Natural Philosophy”, this work was all about the three laws of motion which Newton created that is as follows:
Law One:
The first law says: “any object in motion will continue to move in the same direction and speed unless forces act on it” this means that if there was no gravity, friction or air a ball would continue to move forever once thrown or kicked, because the friction in the air slows a ball down and the gravity pulls the ball down.
Law Two:
The second law says: “the greater the mass of an object, the more force it will take to accelerate the object”. The mathematical formula for this is F=ma which means “Force = mass x acceleration” which means the harder you kick or hit something the farther it’ll
go. Law Three: This law says: “For every action there is an equal and opposite reaction” for example if you hit a ball with a bat, there is the force in the bat and in the ball, which is the equal force, but there is also the force of the ball that goes goes into the bat which is the opposite reaction.
In other words, in the case of an object in motion, unless it is affected by a “non-zero force) force such as thrust or drag, it would continue in the same direction and at the same speed indefinitely. “Horizontal motion is under Newton’s first law; therefore, it is at constant horizontal velocity.
Newtons second law can be indentified more easily using the equation F=ma. This is an equation that is very familiar to those of us that wish to do well in any physics class! This equation tells us many things. First it tells us the net force that is being exerted on an object, but it also tells us the acceleration of that object as well as its mass. The force on an object is measured in Newtons (I wonder where they got that from). One Newton is equal to one (kg)(m)/s^2. For example, if superman pushes on a 10,000kg truck and it is moving at a rate of 2m/s^2, then the force that superman is exerting on the truck is 20,000N. For those of us that wish to move on in the field of physics, Newtons second law (F=ma) will forever haunt us!
Sir Isaac Newton made an enormous amount of contributions to the world of physics. He invented the reflecting telescope, proposed new theories of light and color, discovered calculus, developed the three laws of motion, and devised the law of universal gravitation. His greatest contribution to physics was the development of the three laws of motion. The first law was called the law of inertia; this law stated that, “Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.” The second law is called the law of acceleration; this law stated that, “Force is equal to the chan...
When most people hear the name Isaac Newton, they think of various laws of physics and the story of the apple falling from the tree; in addition, some may even think of him as the inventor of calculus. However, there was much more to Newton’s life which was in part molded by the happenings around the world. The seventeenth century was a time of great upheaval and change around the world. The tumultuousness of this era was due mostly to political and religious unrest which in effect had a great impact on the mathematics and science discoveries from the time Newton was born in 1646 until the early 1700’s.
Quantum Mechanics This chapter compares the theory of general relativity and quantum mechanics. It shows that relativity mainly concerns that microscopic world, while quantum mechanics deals with the microscopic world.
• The first is the Special Theory of Relativity, which essentially deals with the question of whether rest and motion are relative or absolute, and with the consequences of Einstein’s conjecture that they are
Newton’s 2nd Law of Motion states that acceleration is directly proportional to net force when mass is constant. This experiment dealing with variable forces has as its objective the verification of this law. In this experiment this law is tested for verification in straight forward way. Through the use of a Force Sensor and an Accelerometer, data collection of observations and measurements that a force exerts on a small cart along with the cart’s accelerations are to be determined. The sensors’ measurements will be employed to give meaningful relationships between the net force on the cart, its mass, and its acceleration under these conditions. The resultant measurements revealed will verify and determine the force and acceleration relationship as stated by Newton.
In 1905 Einstein published the Annus Mirabilis papers. These papers explained each of his four main theories; the photoelectric effect, Brownian motion, Special Relativity and Matter energy-equivalence. These four works created the foundation for modern day physics and brought a new view to space, time and matter. Brownian motion is the random movement of small particles in either a gas or a liquid caused by collisions with the particles around them. Albert Einstein came up with mathematical equations that allowed him to determine the exact size of atoms. With these equations Einstein essentially provided the first substantial evidence that atoms actually do exist. Einstein’s second paper was on the photoelectric effect. Until Einstein, the photoelectric effect went unsolved. Einstein concluded that when a photon hits a metal surface, the photoelectrons on the metals surface are emitted as certain light frequencies. Thus proving that light has quanta meaning it has packets of energy. This has brought huge technological advancements and has a lot to do with many things that surround us today. Old television used video camera tubes that required the photoelectric effect to charge the screen and transform the image...
It was once stated, “No one knows what the future holds. That’s why its potential is infinite.” No one would have ever believed that space exploration would be possible until Sir Isaac Newton came along and conducted experiments while developing his profound theories. An English physicist and mathematician, Newton was an instrumental figure during the scientific revolution of the 17th century. Not only was Newton known for being the founder of differential and integral calculus, but he was also given credit for other contributions to mathematics including the generalized binomial theorem and his method of finding approximations successively closer to the root(s) of a function (Mastin, 2010). As the result of Newton’s three laws of motion and
Theory is an attempt to explain the unexplained, to give title to the untitled and to give reason to the unreasonable. It is a combination of existing knowledge and newly acquired knowledge that allows us to make assumptions in order to realize reasonably foreseeable outcomes. It is only in the realms of science, physics and mathematics that the repeated application
Physics is involved in everyday life and can be an essential explanation for how things work. Being a lacrosse goalie involves physics concepts and proves how they apply to every movement that is made on the field. To better understand the physics of a goalie, you must understand how Newton’s Three Laws of Motion work; Inertia, force equals mass times acceleration, and equal and opposite forces, as well as another law torque and leverage.
I have chosen two of them who were in many ways just opposites. One is extremely famous and the other is almost unknown except to specialists. The most famous is of course Albert Einstein. He has significantly altered our view of the world with his Theory of Relativity.
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
The theory of Special Relativity, written by Albert Einstein in 1905, describes the laws of motion at velocities close to and at the speed of light. It was written to make the laws of motion consistent with the laws of electromagnetism. Special relativity makes two postulates: the laws of physics are the same for all non-accelerating observers and the speed of light in a vacuum is constant, regardless of motion. One of the consequences of these postulates is that clocks run slower to an observer in motion, or time slows down. Special relativity also states that objects at high speeds always appear shorter in the direction of motion than they do at rest. However, length measurements transverse to the direction of motion are unaffected. Velocity addition is different for special relativity than for classical mechanics because according to special relativity, nothing can travel faster than the speed of light. Also, in order to retain the conservation of momentum as a general law consistent with Einstein's first postulate, a new definition of momentum must be used at relativistic velocities. The twin paradox is the famous example that uses time dilation and length contraction. Special relativity is not contradictory with classical mechanics because at low speeds, all of the laws of special relativity reduce to the laws of classical mechanics.
Sir Isaac Newton Jan 4 1643 - March 31 1727 On Christmas day by the georgian calender in the manor house of Woolsthorpe, England, Issaac Newton was born prematurely. His father had died 3 months before. Newton had a difficult childhood. His mother, Hannah Ayscough Newton remarried when he was just three, and he was sent to live with his grandparents. After his stepfather’s death, the second father who died, when Isaac was 11, Newtons mother brought him back home to Woolsthorpe in Lincolnshire where he was educated at Kings School, Grantham. Newton came from a family of farmers and he was expected to continue the farming tradition , well that’s what his mother thought anyway, until an uncle recognized how smart he was. Newton's mother removed him from grammar school in Grantham where he had shown little promise in academics. Newtons report cards describe him as 'idle' and 'inattentive'. So his uncle decided that he should be prepared for the university, and he entered his uncle's old College, Trinity College, Cambridge, in June 1661. Newton had to earn his keep waiting on wealthy students because he was poor. Newton's aim at Cambridge was a law degree. At Cambridge, Isaac Barrow who held the Lucasian chair of Mathematics took Isaac under his wing and encouraged him. Newton got his undergraduate degree without accomplishing much and would have gone on to get his masters but the Great Plague broke out in London and the students were sent home. This was a truely productive time for Newton.
