The Drake Equation * The Drake Equation was created by Frank Drake in 1960. * estimate the number of extraterrestrial civilizations in the Milky Way. * It is used in the field of Search for ExtraTerrestrial Intelligence (SETI). * National Academy of Sciences asked Drake to organize a meeting on detecting extraterrestrial intelligence. Reason drake equation created * Drake equation is closely related to the Fermi paradox * The Drake Equation is: N = R * fp * ne * fl * fi

Cause and Effect on The Cold Equation In the story "the Cold Equation" by Tom Godwin‚ the author created a cause and effect relationship by having Marilyn decide to stowaway on the emergency dispatch ship that only has enough fuel for one person. Because Marilyn decided to stowaway she ended her own life‚ forced Barton to deal with having to kill a woman‚ negatively affects the results of the mission to Woden‚ and for her parents and brother to deal with her death.

Upstream: 60 = 6(b-c) Downstream: 60 = 3(b+c) There are now two separate equations: 60 = 6b - 6c and 60 = 3b + 3c Solve both equations for b: b = 10 + c b = 10 - c Now make both equations equal each other and solve for c: 10 + c = 10 - c 2c = 0 c = 0 The speed of the current was 0 mph Now‚ plug the numbers into one of either the original equations to find the speed of the boat in still water. I chose the first equation: b = 10 + c or b = 10 + 0 b = 10 The speed of the boat in still water must

velocity of the stream using Equation 1. (Eqn. 1) Where is the flowrate in m3/s and A is the cross-sectional area of the pipe. To find the flowrate‚ we multiply the flowmeter reading by the constant and convert from gallons to cubic meters as follows: The cross sectional area of the 7.75mm pipe is Plugging these values into Equation 1‚ we obtain a bulk velocity . With the bulk velocity value‚ we can find the Reynolds number of the flow using Equation 2. (Eqn. 2) Plugging

The media equation is a theory developed by two professors of communication‚ Byron Reeves and Clifford Nass‚ at Stanford University. The theory is simple. They state that people treat the media as if they were real‚ hence the equation: media = real life. Basically Reeves and Nass are saying that people on an unconscious level perceive the media as real. People view objects of the media are talking to them personally. Reeves and Nass view things such as computers‚ televisions‚ radios‚ and other
