– Richard P. Feynman (11 May 1918 – 15 Feb 1988)

From the Manhattan Project to the Challenger investigation, the physicist and Nobel Laureate Richard Feynman loved to shoot down what he called “lousy ideas.” Today, the world is awash in lousy ideas — so maybe it’s time to get some more Feynman in our lives?

This is paraphrased. What he actually said was:

“The real problem in speech is not precise language. The problem is clear language.”

He went to say:

“The desire is to have the idea clearly communicated to the other person. It is only necessary to be precise when there is some doubt as to the meaning of a phrase, and then the precision should be put in the place where the doubt exists. It is really quite impossible to say anything with absolute precision, unless that thing is so abstracted from the real world as to not represent any real thing. Pure mathematics is just such an abstraction from the real world, and pure mathematics does have a special precise language for dealing with its own special and technical subjects. But this precise language is not precise in any sense if you deal with real objects of the world, and it is only pedantic and quite confusing to use it unless there are some special subtleties which have to be carefully distinguished.”

The above link to the Engineering and Science journal is commentary on, amongst other things, definitions and how they are used in ‘new’ mathematics.

More from Feynman, next time.

PS: I love coffee. BuyMeACoffee, leave a message with a date and time and we can share it, remotely, at the same time, and think about the Cosmos.

In the meantime, take care of yourself and if you can, someone else, too, because as Adam Smith said, “we naturally desire not only to be loved but to be lovely”.

Remember, hope lives here.
