Writing sigma

Hi,
So my PChem professor writes lowercase sigma similar to a number 6 with a curl on the top...(picture attached) To me this looks nothing like the sigma used in my textbook, computer or anywhere online I can find (similar to an o with a horizontal line on top). He insists we use his version of the figure because when we go to grad school we will be "looked down on" if we don't use proper Greek figures. I have no problem with his figure, if it is the correct one. Can anyone explain the discrepancy?

That's no sigma.

Maybe your professor has the palsy in his hand.

Yes, I think that 's right (sigma σ), his tip was just upped and curved too much.

I can see how a sigma ended up like that but I would never guessed it to be a sigma had I not read your post.

Unfortunately, bullying and social exclusion due to imperfectly written greek letters is a common problem in grad school. So, while it shouldn't be necessary, I recommend you do as your professor tells you and write the sigmas properly so you won't be singled out.
