Numberorphile, a famous youtube channel, published this interesting story not long ago, that talks about how the allies counted the number of tanks back in the days of the first and second world wars. A very ingenious and clever trick that can still be used today for so many things.
A very clever strategy that defiled standards and customs back in the day and that can prove to you and show how mathematicians can also save lives using smart estimates based on clever observations.
So to all you math teachers out there.... yaaayy!!!!
