In his theory‚ “tachyons” are able

what others disbelieved- the theory of relativity in the 1900’s. However‚ based on his childhood‚ one would never know that he would be capable of transforming physics majorly. He was an unruly kid‚ getting kicked out of elementary school and only starting to speak at age five‚ which is extremely late for any child. At this point‚ many thought he was an extremely unintelligent person- but he wasn’t‚ as he matured and developed the famous theory of relativity. Another famous example is Bill Gates

particular the area of physics‚ I must say that without doubt there is a theory that promises to have the answer to all our doubts‚ so this time I want to share this publication about of the strings theory ‚ but I want to do it explaining in a very general and simple way to understand given the complexity of this topic. One of the most desired dreams of physics is to find a theory that explains‚ from the formation of atoms to the behavior of stars and even the origin of the universe itself‚ a theory

In Newtonian physics‚ free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity‚ where gravitation is reduced to a space-time curvature‚ a body in free fall has no force acting on it and it moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain. An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards

Physics is a diverse area of study and in order to make sense of it scientists have been forced to focus their attention on one or two smaller areas of the discipline. This allows them to become experts in that narrow field‚ without getting bogged down in the sheer volume of knowledge that exists regarding the natural world. Below is a list - by no comprehensive - of different disciplines of physics. The list will be updated with new additions and definitions as appropriate. Acoustics - the study

Dark Energy VS Dark Matter Dark Matter Dark Matter is the name given to mass that emits no detectable radiation. ‘’Dark Matter accounts for the galaxies rotating about "local groups" in tighter orbits than we expect from our observations. Gravity is stronger than we can account for unless there is some matter we cannot see. We are much more certain what dark matter is not than we are of what it is” (Feild‚ Ann‚ 2013). Scientists think dark matter is made of particles called WIMPS‚ "weakly

The Other Side of Einstein Albert Einstein‚ arguably the greatest scientist and mathematician of all time‚ is mostly known for his prominent scientific discoveries and achievements. He is often perceived by the public as a scientist who lived his life in his laboratory studying‚ void of any social life. However‚ in the essay "My Friend‚ Albert Einstein" by Banesh Hoffmann‚ Einstein’s long time friend attempts to depict Einstein as a humble and compassionate man‚ contrary to the mythological figure

1610‚ Galileo Galilei had publicly announced his support and belief of a Heliocentric Solar System‚ the Sun being the center of Earth. Throughout his life‚ Albert Einstein‚ famous for his general theory of relativity‚ had challenged all theories including Newton’s Laws of Motion. Dating back earlier‚ as early as 240 BC‚ a Greek mathematician named Eratosthenes had come with the theory of how the Earth was not flat. During Georges Lemaitre’s time‚ he had started the hypothesis of the Big

and the universe began to expand rapidly. The universe never sits still. It expands at a gradual rate. In the 1920s‚ Albert Einstein‚ an astrophysicist from Germany‚ had discovered evidence of the expansion of the universe through his Theory of Relativity‚ which was published in 1915. Following the creation of gravity‚ subatomic particles‚ such as protons and neutrons‚ were formed due to the force of the particles colliding with each other. It was actually around three minutes later that protons
