>>8668254Here;s one my first year math phys lecturer said on the first day, and referred to quite often.
A rich man wants to bet on a horse race. He hires three people to evaluate the horses and give their professional opinions on which is best. A geneticist, an anatomist and a physicist.
The geneticist looks at the family lines of the horses. He looks at their parents, their dna, tries to establish which horses are likely to posses the best traits, but there's just so much data he can't deal with it all, and gives up.
The anatomist looks at the horses themselves, studies their musculature, their performance, their builds, but he realizes just how similar the horses are and how random it could be, and abandons the project.
The physicist disappears for a while, only to come sprinting to the rich man yelling "I've found it, I have the answer!"
The rich man asks "Really!?"
The physicist replies "Yes! But it only works for spherical horses in a vacuum."
