... Quarks and leptons are light; but their constituents must be very pointlike (invisible below a TeV). Compare: pions are light, yet quarks are pointlike. Pions are protected by the conservation of the chiral current (PCAC). We need such a protection mechanism for the pentas. Chiral currents can be co ...

Tricking the Uncertainty Principle?

Exact position and momentum are not attributes that any object ever has at the same time. Assuming otherwise leads to incorrect predictions. • ...

The subtraction of 2 ( i.e. 2.00000000000000...) is done for us by the physics, so the measurement gets directly to the radiative corrections. For muons ...

Bell's theorem
.svg?width=300)
Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
