  1. The luminosity of the sun is 3.85 × 1026 W.
    1. Determine the mass of the sun converted to energy in one second.
    2. How many elephants is this?
  2. Fermi National Accelerator Laboratory (a.k.a. Fermilab) in Batavia, Illinois is a US Department of Energy National Laboratory and home of the world's most powerful particle accelerator, the Tevatron, which accelerates beams of protons and antiprotons to ultra-high energy and brings them into head-on collision. Protons in the Tevatron's accelerator ring acquire energies on the order of 1012 elevtronvolts — a teraelectron volt (TeV).
    1. From the Tevatron's energy …
      1. determine the speed of a proton in the accelerator
      2. and then verify (or contradict) the laboratory's claim that protons "circle the four-mile [6.4 km] ring 57,000 times each second."
    2. Determine the mass increase of a proton in the Tevatron in …
      1. atomic mass units and
      2. multiples of the proton's rest mass
