How Do Rocket Engines Work?

April 28, 2023

Rockets differ fundamentally from planes and helicopters in terms of propulsion. Planes and helicopters rely on aerodynamic design for lift and the atmosphere for combustion. How do rockets fly? […]

The Search for Higgs Boson: The LEP Era

March 16, 2023

With the discovery of W and Z bosons, much of electroweak theory had been confirmed. In 1991, the CERN laboratory turned on a much bigger accelerator, called LEP, to look for Higgs boson. […]

Higgs Field and the Search for W and Z Bosons

March 14, 2023

Modern electroweak theory predicted that there should be a massless photon, a massive neutral particle called Z boson, two massive electrically charged particles called W bosons, and a massive and neutral particle called Higgs boson. […]

Higgs Boson and the Higgs Field

March 14, 2023

Electromagnetism and weak nuclear force were unified into a combined force called the electroweak force. The electroweak unification predicted four particles that carried the electroweak force and had zero mass. […]

Can We Make a Subatomic Black Hole?

March 8, 2023

The fears regarding subatomic black holes are not founded. Physicists like Stephen Hawking believe that even if subatomic black holes are real, they evaporate away before becoming dangerous. […]

Are Particle Accelerators Really Dangerous?

March 8, 2023

Though they are certain worries vis-à-vis the particle accelerators, they are not backed by science. One of the concerns is that large accelerators might make subatomic particles, called ‘strangelets’. […]

What Makes Nuclear Fusion Work?

December 23, 2022

Nuclear fusion is an astronomically powerful source of energy. If harnessed, it could prove unimaginably useful for humanity’s purposes. How does nuclear fusion make energy? […]

What Is the Planck Spectrum?

December 21, 2022

0.6 microns is the most popular wavelength to have in sunlight. When we measure the flux density of the Sun, as a function of wavelength, we find it’s a pretty good fit to a theoretical Planck spectrum. […]
