    Professor Dave... I pay £9000 for uni every year but what I learn from you is ten times more understandable to me than anything my lecturers teach.
    I just wanted to say thank you so so so much for putting all this material up for free for us because you are saving my life at the moment I LOVE YOU! KEEP UP YOUR GOOD WORK I hope you get anything you want in life you good man

    That is probably the best explanation on Newman Projections ever. I understood the subject in less than 15 minutes otherwise I'd probably spent at least 2-3 hrs to understand whats going on. Big thanks as always Prof. Dave!

    I know many people say this, but by far, you are the best organic chem professor/teacher i have ever come across. It's crazy how many hours we spend in class to learn something, when this man teaches it in under 20 minutes. It blows my mind, truly. Thank you, sir.

I googled it when i was in 9 class because it was the weirdest unit of distance i ever heard. do you have a chart of your channel or syllabus or study map or something so that i can see whats in what videows or playlists. if not i would still make use of video labels , even though it may take some time

I have read that the front carbon is represented through a central dot and that the circle is representing the back carbon. Is this simply another way to interpret, to imagine, to depict the Newman projection or is one of the theories wrong?
