Back to the Future
In December 2015, a new law titled “Low Volume Motor Vehicle Manufacturers Act” (H.R.2675) was introduced in the U.S., which creates a reasonable regulatory structure allowing small companies to produce a limited number of completed replica motor vehicles that resemble the appearance of cars produced 25 years ago or more. Suppose that upon finding this out,
you dish out all your savings (plus a loan from your parents) and buy a DeLorean.
The answer to the following question is more interesting than the question itself. Consider the experiment of tossing a
fair coin until you get two consecutive
heads. What is the probability distribution
of the number of tosses?
Consider a He-filled balloon with a volume of 1 cubic meter. At 25°C and 1 atmosphere pressure, can you hold it without floating away?
Bonus Problem: Self-Heating Container
OnTech, a San Diego startup company, has developed self-heating containers for meals and beverages.
These containers will heat coffee to an optimal drinking temperature of 145 degrees F within minutes after pressing a button.
