# Translation of handwriting into readable form

Please see attached pic. I have received a handwritten document from a physicist. I am not familiar with the equations, therefore the symbols are difficult to figure out. I have done some searches. I know the first symbol is the "time second derivative" and another symbol is the "time derivative" a lot of the others I have difficulty discerning. Thanks for any help.

That scan is too low resolution, but other than that, what exactly are you asking? Transcribe the whole thing in latex? I dont' think so. Anyway I see a lot of y's, phi's, and exp's.

Why would you settle for guesses when you can ask the person who sent you this?

The person wrote it is deceased, Richard Feynman. With knowledge of the work, I assumed some would be familiar with the equations. Therefore making it simple to make them more readable.

Why didn't you say so? Which part do you not understand?

I don't know what character has the loop, I don't need LaTex, just the name or function

Lowercase phi.

$\varphi_n - \varphi_{n+1}$
