ME 125NT Introduction to Nanotechnology Quiz #1 re-Take option Question #1 (10 points): Scaling questions. Please write down as much as possible and cite your source when relevant. a. How many square nanometers is a standard piece of paper? b. How many square nanometers is the Empire State Building? c. How many nanoliters are in a gallon of milk? d. How many nanowatts does it take to power an iPod? e. How many nanograms does the earth weight? Question #2: (20 points) In Richard Feynman's Lectures " There's Plenty of Room at the Bottom " 1959 and " Tiny Machines " (1984) he asserts that all of the knowledge of humanity (textual knowledge at the time of his lecture) can be stored in a volume the size of the smallest dust particle. a. Follow his assumptions and do this calculation based on the data he provides from 1959. b. Suppose you wanted to use DNA to store all of the textual knowledge of humanity (in 1959), could it theoretically fit within a cell nucleus (assuming 1 base pair = 1 bit)? c. Why can’t the internal combustion engine (as it is designed to work macroscopically) scale down to a “tiny machine”?
