We introduce the standard model of elementary particles and discuss the reasons why we have to modify it. Emphasis is put on the indications from the neutrinos and on the role of the Higgs particle; some promising theoretical ideas, like quark-lepton symmetry, existence of super-heavy ``right...

In a study, scientists say they can explain dark matter by positing a particle that links to a fifth dimension. Here's what that means.
What is the Rutherford model of the atom? Discovery of the Atomic Nucleus: Rutherford discovered the atomic nucleus in 1911 when he attempted to pass a beam of alpha particles through a thin sheet of gold foil. Rather than passing through the sheet unimpeded, some of the alpha particles bounc...
What shapes the universe? The gravitational effect of matter can affect the curvature of space, per general relativity, but quantum effects during the Big Bang also influenced the shape of the universe. Is the universe a sphere or flat? Whether the universe is flat or curved like a sphere ...
These particles and forces are the subject of theStandard Model of Particle Physics. Scientists also get insights into the quantum physics that govern how the world behaves at incredibly small scales. In the quantum realm, the classical Newtonian physics that we live with every day is insufficient...
Photonics is a multidisciplinary domain that involves the generation, control, manipulation, and detection of light.
in particle system is not continuous strictly speaking, however when we are speaking a large amount of measured particles, we can say it is continuous. The size distribution of polydisperse particle system made up of particles in different sizes is divided into Unimodel and Multimodel. ...
