Project 8 And The Ghost In The Particle Machine

Neutrinos are among the more mysterious elementary particles in the universe: Billions of them pass through every cell of our bodies every second, yet these ghostly particles are incredibly difficult to detect, because they don’t appear to interact with or ...

Searching For The A Boson

Besides being a giant triumph of theoretical physics and the definitive seal on the correctness of the Standard Model-at least at the energies at which we are capable of investigating particle physics nowadays-, the 2012 discovery of the Higgs boson by the ...

The Lead Zeppelin And Buoyancy

When a feather or a plastic bag or almost anything light is placed in water, these items will generally float.   This is easy to understand if you think of water being more dense than the other item.   If you put something heavier in water, it tends to si ...

The Quote of the Week: Who Called the Higgs Boson The Higgs Boson

"B.W. Lee also carries much of the responsibility for calling the Higgs boson the Higgs boson, mentioning repeatedly 'Higgs scalar fields' in a review talk at the International Conference on High-Energy Physics in 1972." J. Ellis, M.K. ...

The difference between detectable, legal and dangerous exposures to radiation

Detecting ionizing radiation does not mean that a disaster has or will occur.  Detecting radiation is generally a good thing if the radiation is expected, intended or natural.  We and all living things on earth are naturally radioactive.  This is due prim ...

Stuff Worth Reading: Collider Asymmetries, Dark Photons, And Warp Drives

As yesterday in Italy was the equivalent of Labor Day, and today is a Saturday, with people around me exploiting the three-day rest for a recreational trip, I do not feel in a very productive mood, so rather than writing something original here I will expl ...

Light Pushes Matter One Million Times More On Superconducting Island

When a mirror reflects light, it experiences a slight push but it is negligible in our everyday lives. Our furniture is not moving because due to radiation pressure of light, a 100 Watt light-bulb causes a radiation pressure that is only a trillionth (one ...
