An analysis of the state of stresses generated by torsion in twisted non-circular bars Abstract One of the main problems that must be solved in the design of the machine components stressed in torsion is to establish their optimum shapes and dimensions in order to resist for a given twisting load. Also, in the case […]
History of the model of the atom The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called “atom”. However this atomic theory of Democritus was criticized by Aristotle who proposed a […]

Get startedThe variation of light intensity with distance; namely the inverse square law of light intensity with distance. Background Theory Light emitted from any kind of source, e.g. the sun, a light bulb, is a form of energy. Everyday problems such as lighting required for various forms of labouring or street illumination, require one to able […]
Albert Einstein Albert Einstein was a German-born physicist who developed the general theory of relativity. He is considered one of the most influential physicists of the 20th century. Who Was Albert Einstein? Albert Einstein (March 14, 1879 to April 18, 1955) was a German mathematician and physicist who developed the special and general theories of […]
The quality of life today at so many different levels has greatly improved due to use of scientific knowledge, this range from the mere daily activities to global activities. Application of science informs policy making and greatly play very critical role in social, political, economic, cultural, and demographic fields across the world. It is apparent […]
Many believe the universe all come about over 10 billion years ago. It all started out as just a little blob which got hot and dense. Suddenly, this bubble got bigger and bigger and bigger. This created the Universe we live and do daily task within. You may think to yourself, “How can a force […]
Abstract As humans, we evolve and learn new things about our world continuously. Using science, we create new medications, innovative technologies, and find new discoveries. We rush to create the future before we even take the time to think about the past and how we got to where we are today. Have you ever wondered […]
Monsignor Georges Lemai®tre was a Belgian Roman Catholic priest, physicist and astronomer. He is credited with the first precise formulation of the idea of an expanding universe and what was to become known as the Big Bang theory of the origin of the universe, which Lemai®tre had called his “hypothesis of the primeval atom.” Lemai®tre […]
Before the Big Bang, there was no differential between space and time. There was no light and everything ceased to exist. It is believed by most scientists that about 13.7 billion years ago, the universe began. This became known as the Big Bang. An immense amount of energy and force was condensed into a tiny, hot […]
How did the universe get to be so big? Where did it come from? How did it all start and end up like today? These are just a handful of the questions being asked about the birth and opening creation of our beautiful universe as we know it. As imperfect humans, it’s likely that we […]
Since the beginning of human history, we have strived to understand how our we and our universe came into existence. It is from our histories that many tales of how we came to be grew out of mystical attempts to explain the unknown. Our quest to study the cosmos has given us strong theories that […]
The big bang theory is a theory of how the universe started. Most people do believe that the big bang theory was the start of the universe, but then you have some that don’t believe that. They believe that the universe was always here and that there was nothing that created it. You also have […]
The Big Bang was the beginning of everything. All elements of matter come from the Big Bang in our universe. It all began when Einstein’s theory gave better understanding of gravity pull and Edwin Hubble discovered that the galaxies are always moving apart from one another. In 1964 Arno A. Penzias and Robert W. Wilson […]
The expansion of the universe has been explained from the Big Bang theory. The Big Bang described how elements were made and how planets and stars were created. The expansion could be explained by inflation, which could have created a numerous number of universes. Dark energy is able to explain why the universe has expanded […]
The big bang theory is the most popular explanation of how our universe came to be. “according to the standard theory our universe sprang into existence as ‘singularity’ around 13.7 billion years ago” – (insert citation). A singularity is a space believed to be in the core of a black hole. A Black hole’s pressure […]
The Big Bang Theory aka the early state of the universe is a cosmological model that was created in seconds like ” boom there it is”it all happened in a Big Bang ..it’s basically how the universe began at its simplest , as we know it started as a small singularity then it inflated into […]
The Big Bang Theory is the leading explanation of how the universe was created. It was discovered by George Lemaitre, and proved by many scientist’s data, that was later used as evidence. The theory explains how the universe expands and other scientific explanations such as the origin of all matter. The Big Bang Theory is […]
Some people are still weary about this theory. The leading hypothesis about the universe’s birth solved many puzzles and fits all observations. This “cosmic inflation” hypothesis lacks actual, real proof. The absence of the “ripples” has fueled some weaker theories of cosmogenesis in recent years. Alternative idea say that the ripples would simply be too […]
The Big Bang Theory was invented by astronomers, who used mathematical calculations along with observations to come up with the idea of how the universe begin. The mathematical part of the Big Bang theory is a combination of Albert Einstein’s general theory of relativity and theories of fundamental particles. Today the National Aeronautics and Space Administration […]
Time traveling. What is time traveling? It is, indeed, as simple and basic as it sounds; it is the concept of moving through different points in time throughout space. To put time travel on such a high pedestal of success, some might say that this sounds like a great power to possess aside from the […]
Picture this. You visualize yourself standing outside and gazing upon the stars and you wonder how was the universe created. The universe was formed by what we know as the big bang theory. The universe began 14 billion years ago, according to scientists. Even though the big bang might not seem intriguing to you, there […]
So basically the Big Bang Theory is the idea that something most likely a star with an incomprehensibly large mass supernovaed and created our universe and everything in it. It started with all the people living in times up to the 20th century who believed that the universe was ageless and infinite. But then Albert […]
Through human history, war has always developed new technologies that are advancements outside of war. World War I and World War II were the most influential periods in human history in terms of technological improvement. When Marie Curie created the x-ray she created one of the most important recent medical advancements. When Lewis Nixon invented […]
