It is possible for an electron and positron (an anti-electron) to be spontaneously
created, so long as they annihilate a short time later. Explain this in terms of
the Heisenberg uncertainty principle. Calculate the minimum energy necessary to
produce an electron-positron pair and estimate the time for which such pairs can
exist.

A subatomic particle created in an experiment exists in a certain state for a time of ?t = 9.8 × 10-20 s before decaying into other particles. Apply both the Heisenberg uncertainty principle and the equivalence of energy and mass (see Section 28.6) to determine the minimum uncertainty involved in measuring the mass of this short-lived particle.

The Large Electron-Positron Collider (LEP) was an accelerator at CERN, the International particle physics laboratory in Europe. As its name implies, at LEP electrons (e- with mass of 0.51 MeV/c2) were collided close to head-on with their anti-particle, positrons (e+ with the same mass). Each of these particles was accelerated to an energy of 104.5 GeV by the time they collided. What is the Lorentz factor $\gamma$ of an electron at this energy? How fast as a fraction of the...

TOMS SHOES –Case Study Founded in 2006 by BLAKE MYCOSKIE, TOMS Shoes was an American footwear company based in Santa Monica, California. Although TOMS Shoes was a for-profit business, its mission was more like that of a not-for-profit organization. The firm’s reason for existence was to donate to children in need one new pair of shoes for every pair of shoes sold. Blake Mycoskie referred to it as the company’s “One for One” business model. While vacationing in Argentina during...
