Certain mathematical equations contain unnerving dangers, Arguably, E=mc^2 is the most famous equation in science. C is a very large number. But in Einstein’s, equation it is squared. This means that mass contains an insane...

If you ask a physicist, what is at the core of physics, you will hear symmetry. What is symmetry? Gauge theory explained simply.



Symmetry is about actions that don't change anything. If we take an...

What is the Electroweak force? Electroweak theory explained: At the moment of the Big Bang, all 4 fundamental forces were probably the same. But as temperatures and energies lowered, the forces separated into...

Does a final theory exist that can end our reductionist probing into ever shorter distances? Or is there no end to reductionism? There should be an end point because as the object of our measurement gets small...

SUMMARY

In April 2022, a team at Fermilab announced that the W-boson was measured to a new level of 7 sigma precision- 80.4335 giga electron volts (GeV) plus or minus 0.0094 GeV. However, this was not...

Summary:

Everything you can see is made of up of the same fundamental particles. The best theory of fundamental particles and forces is the Standard model of particle physi

This content defines angular momentum (ℓ) for a particle as the cross product of its position vector (r) and linear momentum (p), i.e., ℓ=r×p=m(r×v). It clarifies that angular momentum is a vector quantity defined with respect to a...

Why do dunes sing? Head into the mysterious world of sand with host Joe Hanson! Along the way we meet Dr. Melany Hunt and Dr. Nathalie Vriend who solved the longstanding mystery of why dunes sing.

Was the Universe Designed? Exploring the effect Dark Energy has on our Universe.

In part two of our series on Theory of Everything, we explain particle physics using string theory.

Hawking radiation was first discovered by English scientist Stephen Hawking in 1974. Prior to this discovery, our knowledge of black holes was very limited. It was believed that black holes were completely black and that they did not...

The Higgs boson is a wave, ripple or disturbance in an invisible, all-permeating field called the Higgs field. In the year 1964, Peter Higgs, François Englert and four other scientists proposed a rather unique idea to explain why certain...

Celebrated physicists Nobel Laureate Tony Leggett (University of Illinois), Freeman Dyson (Institute for Advanced Study), Paul Steinhardt (Princeton University), Michael Gordin (Princeton University) share their intriguing perspectives...

Theoretical physicist Rocky Kolb, University of Chicago, describes the uniquely enriching experience he had of learning astronomy side by side with his graduate school advisor and mentor.

Imperial College cosmologist Claudia de Rham describes her view of how reinterpreting Einstein's theory of gravity in terms of particle physics gives a more coherent and elegant picture of the forces of nature.

Caltech theoretical physicist and Nobel Laureate David Politzer shares his excitement at re-appraising information loss in black holes and re-examining the mathematics of gauge theories.

Nobel Laureate in Physics Anthony Leggett (Illinois) describes the so-called Anthropic Principle that some invoke to answer the "fine tuning problem" of cosmology.

Astrophysicist Scott Tremaine (Institute for Advanced Study) reflects upon the contemporary relationship between theory and experiment in fundamental physics.

Physics majors study the universe, from electrons and protons to supergiant stars.



As a physics major you will take A LOT of math and apply complex formulas to the problems at hand. Physics majors don't just learn the...
