Old Business - Questions Do the solstices and the equinoxes have the same names in the Southern Hemisphere as in the Northern Hemisphere since the seasons are reversed? No, the solstices and equinoxes are reversed too. They match the seasons in the Southern Hemisphere How big is the Higgs Boson? Mass of new “Higgs” Boson => 125.3 +/-- 0.4 GeV (CMS) Mass of new “Higgs” Boson => 126.0 +/-- 0.4 GeV (ATLAS) Mass of Proton => 938.272056 MeV => Higgs is > 125x bigger Mass of Proton => 938.27231 MeV
Postion: Pre-Tutorial Question You observe a star rising due east. When this star reaches its highest position above the horizon, where will it be? High in the northern sky High in the eastern sky High in the southern sky High in the western sky Directly overhead

Position: Post-Tutorial Question 1 When observing at night, how much of the celestial sphere can an observer on Earth see at one time? Less than half Exactly half More than half
Position: Post-Tutorial Question 2 Stars that never set are called circumpolar. As you move from the Earth’s equator toward the North Pole, the number of stars that are circumpolar increases decreases stays the same
Motion: Pre-Tutorial Question • Imagine you are standing outside at night in Albuquerque. Looking directly north, you see a star just above the horizon. A little while later you notice that it’s position has shifted slightly. Which way did it move? • east (to your right) • west (to your left) • up (away from the horizon) • down (closer to the horizon)
