The deconstructed Standard Model equation - symmetry magazine
The deconstructed Standard Model equation. 07/28/16. By Rashmi Shivni. The Standard Model is far more than elementary particles arranged in a table. The Standard Model of particle physics is often visualized as a table, similar to the periodic table of elements, and used to describe particle properties, such as mass, charge and spin.
What is a “particle”? - symmetry magazine
Everyone has heard of Einstein’s famed E=mc 2. Part of what that means is that making a particle requires energy proportional to its mass. Neutrinos, which are very low mass, are easy to make; electrons have a higher threshold, while heavy Higgs bosons need a huge amount of energy. Photons are easiest of all to make, because they don't have ...
Ten things you might not know about antimatter
Antimatter is the stuff of science fiction. In the book and film Angels and Demons, Professor Langdon tries to save Vatican City from an antimatter bomb.Star Trek’s starship Enterprise uses matter-antimatter annihilation propulsion for faster-than-light travel.. But antimatter is also the stuff of reality. Antimatter particles are almost identical to their matter counterparts except that ...
symmetry magazine | dimensions of particle physics
Meet the short-lived particle that helps the sun shine. An online magazine about particle physics. Symmetry receives funding through the US Department of Energy. Symmetry is an online magazine about particle physics and its connections to other aspects of life and science, from interdisciplinary collaborations to policy to culture.
The particle physics of you - symmetry magazine
About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. While most of the cells in your body regenerate every seven to 15 years, many of the particles that make up those cells have actually existed for millions of millennia.
US physicists prioritize closer study of the Higgs
Oct 8, 2024 · In 1964, the same year the Beatles rocked their way into the hearts of Americans on The Ed Sullivan Show, British theoretical physicist Peter Higgs and five of his colleagues proposed a solution to a lingering mystery within the Standard Model of physics.. In 2012, after an almost five-decade-long search, the ATLAS and CMS experiments at the Large Hadron Collider at CERN near Geneva ...
The Planck scale - symmetry magazine
The Planck scale. 05/19/16. By Rashmi Shivni. The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws. Using just five constants in nature (including the speed of light and the gravitational constant ...
What is a photon? - symmetry magazine
What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible packets of electromagnetic energy. If you are reading this article on a screen or a page, streams of photons are carrying the images of the words to your eyes. In science, photons are used for more than just illumination.
What the Higgs boson tells us about the universe
02/21/23. By R.M. Davis. The Higgs boson is the only fundamental particle known to be scalar, meaning it has no quantum spin. This fact answers questions about our universe, but it also raises new ones. When it was first discovered in 2012, the Higgs boson captured the popular imagination and became the subject of intense scientific scrutiny.
Eight things you might not know about light - symmetry magazine
Here are eight enlightening facts about photons: 1. Photons can produce shock waves in water or air, similar to sonic booms. Nothing can travel faster than the speed of light in a vacuum. However, light slows down in air, water, glass and other materials as photons interact with atoms, which has some interesting consequences.
