Gravity keeps our feet on the ground and it keeps us from jumping into space; it sends apples to fall on Isaac Newton’s head, and even though gravity is responsible for keeping the planets in their orbit, gravity still only plays a very small part at the atomic and quantum level.
Since atoms are made up of protons and electrons most atoms should collapse into themselves or other atoms, since positive charges and negative charges attract each other together like a magnet.
It is because of a fundamental force called strong nuclear force. The strong nuclear force acts like a bond of sorts, binding or keeping the protons and neutrons together into the nucleus, but the nuclear force doesn’t go past the nucleus. The strong nuclear force is the key part in human survival; if the strong nuclear force ever decided to disappear, life would never cease to exist. This glue, this force, even though it is so small, has enormous power. When the first atomic bomb detonated, but when the bomb detonated, the power that came out of the atomic bomb equaled to about 20 thousand tons of TNT. With that kind of powerful explosion that the scientists unleashed, was the strong nuclear force. By breaking the bonds, the force, of that glue and splitting the atom apart, unbelievable amounts of destructive energy is released. If anyone ever figures out how to control this, we can create unlimited power, as everything we see today is made out of atoms, but there is a large problem, this destructive power is almost impossible to control.
Another force, the weak nuclear force, without it life would be impossible. The weak nuclear force has a large responsibility for the radioactive decay of an atom. Without radioactive decay, radiation would be im...

...From the vantage point of the third dimension, we can visualize the different parts of the plain unified into a single picture. Likewise, the vantage of the eleventh dimension, looking down on the tenth dimension. As we see the crazy spread of five superstring theories as if they are different patches of the eleventh dimension.
There is one major flaw in any version of string theory, that there is no proof that electrons are more than just point particles, let alone strings inside them. Until there is correct evidence that there are stings, string theory is only but a theory, nothing else. To prove string theory, it is going to cost billions of dollars to build microscopes that can peer into the core of electrons to see if this is true. Until that day comes, scientists will argue over each other upon string theory as they try to see who is right and who is wrong
The development of atomic bomb boosted the level of understanding in terms of physics and chemistry of that particular time period. Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”. When the released neutrons attach to other isotopes of Uranium 235, this can result in a chain reaction of fission. For every generation of fission, the amount of fission is doubled, and this resulted in an extreme outburst of energy. The amount of energy released by this process is related to Einstein’s famous equation “E=mc^2” (Wolf).
An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. The protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others. Protons are positively charged and electrons are negatively charged. Protons and electrons both have charge of equal magnitude (i.e. 1.602x10-19 coulombs). Neutrons have a neutral charge, and they, along with protons, are the majority of mass in an atom. Electron mass, though, is negligible. When an atom has a neutral charge, it is stable.
Based on the data obtained, Figure 1 represents a force vs. time graph for the amount of force that was used to pull a wooden block across a table. As illustrated in Figure 1, the initial flat line in the graph represents the block at rest, this is where the forces acting on the object are the normal force, gravity, and the static frictional force. Force was then applied to the wooden block until it began to move, the point at which the block moves is the peak in Figure 1. This is the point at which there was enough force applied to the block to overcome the maximum static friction force. The graph then begins to decrease because once a force is applied to the object that is greater than the maximum frictional force, not as much force is needed to continue to pull
The amazing transformation the study of physics underwent in the two decades following the turn of the 20th century is a well-known story. Physicists, on the verge of declaring the physical world “understood”, discovered that existing theories failed to describe the behavior of the atom. In a very short time, a more fundamental theory of the ...
... major role in everything people do. Gravity makes all of the important things such as machines or activities people do actually occur. Gravity is also essential to any machine, because they generally need a solid ground to be on. If you were to use a catapult without gravity, you would fling the payload and it would keep flying. It would never hit the ground. Gravity is essential to the success of catapults and just about everything else.
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 atomic bomb1 is the most destructive weapon known to mankind. A bomb of this nature is capable of obliterating anything up to four square miles and anything reaching outside that area receives very extreme damage. Albert Einstein was the man who had convinced the United States to research the Atomic Bomb.
After the first few days of the bombings of Hiroshima and Nagasaki Americans, without knowledge of the aftermath of these cities, began cheering and celebrating as the bombings marked the end of World War II. Also, this event showed that Americans would be the ones who would lead the world into the nuclear age. In a Gallup Poll taken from August 10-15, 1945, Americans were asked whether or not they approved or disapproved of the use of atomic bombs on Japanese cities, 85 percent approved, ten percent disapproved and five had no opinion.30 then when asked if the development of the atomic bomb was a good or bad thing, 69 percent said it was a good thing, 17 percent said it was bad, and 14 percent had no opinion (Steele).
The atomic bomb is a powerful, explosive nuclear weapon. It is fueled by the fission of the nuclei of specific amounts of plutonium or uranium, in a chain reaction. The strength of the explosion created by one of these bombs is equal to the strength of an explosion created by thousands of tons of TNT.
The nuclear arms race was a race for nuclear dominance between the United States and the Soviet Union. It took place during the cold war. The definition of an arms race, made famous by nuclear arms race during the Cold War is a rapid increase in instruments of military power. A nuclear arms race is one where the instruments are nuclear weapons. The designs and testing of the first nuclear weapons during WWII by the US was called the Manhattan Project. The USSR was not officially informed about the Manhattan project until about 3 years later when Stalin was briefed at the Potsdam Conference on July 24 1945, this conference was 8 days after the first successful US test of nuclear weapons. They soon regretted telling the USSR from a fear that the USSR would inform German spies of the Manhattan Project or that the USSR would expect some insight on the technology of these weapons. In August 1945 a month after the Potsdam conference President Harry Truman ordered two bombs two be dropped on Japan, one hit Nagasaki and one hit Hiroshima. In the years after WWII the US had a monopoly on information about nuclear technology. Behind the scenes the USSR began work on their nuclear weapons but they were limited because of a lack of uranium. Then, the USSR discovered uranium in Eastern Europe which boosted their technology. nuclear experts predicted the Soviets would not have their first nuclear weapons until about 1955 but they detonated their first test nuclear weapon in 1949. The US tested their first hydrogen weapons at the Bikini Atoll in 1954. Both countries spent massives amounts on the quantity and quality of their weapons. For many decades the amounts of nuclear weapons and technology for the USSR and the US went back and forth. Curre...
The theory of quantum mechanics has divided the atom into a number of fundamental sub-atomic particles. Although the physicist has shown that the atom is not a solid indivisible object, he has not been able to find a particle which does possess those qualities. Talk of particles, though, is misleading because the word suggests a material object. This is not the intention for the use of the word in quantum physics. Quantum particles are, instead, representations of the actions and reactions of forces at the sub-atomic level. In fact, physicists are less concerned with the search for a material particle underlying all physical objects and more interested in explaining how nature works. Quantum theory is the means that enables the physicist to express those explanations in a scientific way.
The understanding that matter was composed of atoms was changed with the discovery of smaller particles than the atoms, which are protons, neutrons, and electrons. But during the 1960’s, the multitude of particles being discovered was making the understanding that matter is composed of protons, neutrons, and electrons, insufficient. Murray Ge...
The Effects of Gravity There are some people who worry when they're outside, if they don't keep a good grip on the ground, they'll just go flinging off into space. They needn't really worry. about this, because gravity generally keeps that sort of thing from happening. The thing is, no one is really sure what causes gravity, but the effects have been studied by many. physicists and astronomers of the world.
The nuclear arms race was a competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War.(Nuclear Arms Race, Wikipedia)
Gravity is the force that pulls two objects together, and the mass of the human body depends on gravity. The more the mass there is, the amount of the gravitational force will increase. The study of the Earth’s gravitational field itself is complex and deeply fascinating. Likewise, studying its relation to the human body makes it even more thought provoking. A gravitational field is simply the area of space neighboring a body that has another body experiencing a gravitational attraction force. As human beings and just general species, our state in Earth is not the same as it is up in the atmosphere or another planet. Unfortunately, the term “gravity” is thrown around futilely these days, but in this essay you will learn its purpose in our Earth, and all the notions that go along with it.
