Secondary Antiprotons in Galactic Cosmic Radiation

By Stephen Rosen

ABSTRACT

Calculations are presented of the production of secondary antiprotons due to inelastic collisions of high-energy primary cosmic rays with interstellar gas nuclei. Cosmic-ray diffusion theory is assumed to apply in the steady-state approximation, with a constant average beam intensity taken over space. The cosmic-ray energy spectrum, production thresholds, cosmic-ray and target abundances and densities, and production and annihilation cross sections are examined and utilized. The results give a very approximate energy spectrum for the antiproton flux. Astrophysical ramifications of this collision source of antiprotons are discussed in light of the dominance of leakage over annihilation as a mechanism of antiproton loss.

Einstein and the Beatles

East Hampton Star

By Stephen Rosen

In hindsight, the Beatles were as Nobel worthy as Bob Dylan or Albert Einstein.

They’re always quoted. Their words mutate, not into gold, like a surreal version of the Midas touch, but into printer’s ink. They inspire intense admiration. They stand on tall pedestals. They display outrageous behavior. Boldness. Notoriety. Irreverence. Blasphemy. Albert Einstein, the Beatles, and Bob Dylan inhabit public universes linked by Google.

Google “the Beatles” and you get 81.4 million results, “Albert Einstein” yields 131 million results, and “Bob Dylan” 52.9 million. This is “Google fame” (which didn’t exist in the heyday of the Beatles), not Nobel selection committee voters. Would the committee have attached appropriate importance to the apparently infinite I.Q. of Google fame?

A triple coincidence — of their work, their personalities, and an avid press — produced a perfect storm of publicity and an avalanche of recognition for Einstein, Dylan, and the Beatles. Today we would call them rock stars, defined as those special individuals who inspire intense admiration. Original, thoughtful, creative rebels, they rejected what came before them. “To punish me for my contempt for authority,” Einstein said, “fate made me an authority myself.”

The Beatles ignited a firestorm of negative publicity in 1966 when John Lennon asserted, “I don’t know which will go first — rock ’n’ roll or Christianity” and “We’re more popular than Jesus.” (Not true, by the way: “Jesus” gets 10 times more hits on Google than “The Beatles.”)

In 1919, a journalist asked Einstein what he would do if observations failed to match his theory, and he famously replied, “Then I would feel sorry for the good Lord. The theory is correct.” Dylan said, “I’m the spokesman for my generation.” Is that as irreverent, confident, and arrogant as the blasphemous Beatles?
