Steve was walking down the hallway and smelled something good. He then walked into the room and saw 12 peanut butter cookies on a plate on the table. Since his friend Kathy likes to make peanut butter cookies, Steve assumed that she made the cookies. When Steve found Kathy later, he thanked her for making the cookies. Kathy told Steve that she did not make the cookies, but that she saw their friend Jeremy carrying in two bags from the grocery store. Steve asked Jeremy if he made peanut butter cookies. Jeremy said he did not make them, but explained that he heard somebody at the store say that the peanut butter cookies were good, so he bought some to share with everybody. Steve told Jeremy that the cookies tasted delicious. What are 2 qualitative observations from the passage above?

Comedians like to joke that the reason we haven’t been visited by intelligent life from elsewhere in the universe is that aliens have been monitoring earth’s broadcasts of intellectually embarrassing tv programs, like gilligan’s island, fear factor, the jersey shore, and the jerry springer showand so consider us far too primitive to merit a visit. let’s check the assertion that aliens could have been receiving them. tv programs are broadcast at a frequency of about 100mhz with about 100kw of total power in 30frames per second, which emanatesroughly uniformly in all directions. assume that interstellar space transmits these broadcasts without attenuation. no matter how smart they are, aliens would require at least one photon per frame to interpret our signals. findthe number of photons per unit time per unit area reaching a receiver on a possible planet in the nearest star system, which is about 4 light-years away (a light-year is the distance light travels in a year). if aliens aimed a receiver or detector directly at earth, how big (in diameter) would it have to be to receive a photon per frame
