Before we know Physics let’s take a quick overview of Science. Science Definition The Study of Nature is called Science Science, as currently defined, proposes critical knowledge and tries to describe reality and explain it by means of laws that are universal propositions that establish under what conditions certain events will occur, thus allowing the prediction of …

Is reality an Illusion? Quantum theory can only be expressed in mathematical terms and describes matter as an abstraction. In this sense, matter does not inhabit a specific space or time; it is prevalent throughout the Universe and in a constant discontinuous, spontaneous, and unpredictable movement in the Universe. Elementary particles do not obey predetermined …
The bosonic string world sheet action for a string propagating in flat 26-dimensional spacetime with coordinates Xm(s,t) can give rise to four different quantum mechanically consistent string theories, depending on the choice of boundary conditions used to solve the equations of motion. The choices are divided into two categories: A. Are the strings open (with …
If you live near a chemical plant, highway, or train, you are in danger of a potential chemical accident involving either a solvent type substance, gaseous and vaporous, oily and all possibly highly flammable. If you live in any of these areas, it could happen although the incidents are rare. You should have a plan …
Physics is a huge subject that covers many different topics going from galaxies in the depths of space right down to subatomic particles. And if you don’t already know physics it’s difficult sometimes to see how all these different subjects are related to each other. In this article, we are going to show that in …
Particle physicists have a habit that on the face of it seems to violate physics. They set the values of natural constants such as the speed of light and Planck’s constant to the number one. How can they do this? It’s because the relationship between units by which we measure length, time and energy is …
