A man decides that he’s going make a fortune betting on horses with the power of Science. So, to get Science on his side, he consulted (or tried to consult) a number of scientists.
“There are too many variables,” said the Statistician. "You’ll never predict anything with certainty.“
"Are you crazy?” said the Engineer. "A horse is far too complicated for me to guarantee any outcomes.“
"Any particular horse will deviate too much from a standard case for me to be of much help,” said the Biologist.
Finally, in desperation, the man turned to the Physicist. To his surprise, he received a “Hm, that might just work,” in response. "Come back once I’ve had time to fiddle with the problem.“ So, the man went off for a few days and returned to ask for the algorithm, but the Physicist said he was still working on generalising the problem. "Come back in a few more days.” When the man did so, however, he was greeted with much the same response. "I’m simplifying some equations for idealising purposes,“ said the Physicist, apologetically. "Just a couple more days, and I’ll have the basic formula.” So, now at a point of despair, the man returned two days later to find the Physicist hard at work.
“Have you finally got the algorithm?” he asked, irritably.
“Yes, yes, the basic version, at least!” answered the tired-looking Physicist.
“Very good,” the man answered, relieved. "Tell me about it!“
"Well, assume the horse is spherical…”
