If that ever happened, it would rip a hole in the space/time continuum, and the demonic hoardes of Azathoth would be unleashed upon our reality. Iä! Iä! Cthulhu fhtagn!

    Hello, I am a Calculus instructor at a University in the midwest. I wanted to let you know how much I appreciate your channel as a resource. I have a link to this channel on my course WebSite so that students can review topics that they need to. Your clear and thoughtful explanations are a great service to many. Thank you for the time and effort you put into this channel!

      @@jamescoughlin8856 right, most useless professors dont know how to hold lectures instead tell students to read the textbook and watch professor Leonard videos if we have trouble. How is this "teaching"? These people get paid over $100k+ and does absolutely nothing besides tell people to read text book and direct their students to watch someone else's video because they suck at doing lectures of their own.

      @@jamescoughlin8856 have absolutely no shame in being the most useless "teachers" some are no longer calling themselves "teachers" or "professors" instead call themselves "instructors" because all they do is ask students to read the textbook, use someone else's resource to learn while they put absolutely zero effort in teaching students and gets paid $100k+ this is why i never participated in the whole professor layoff thing, i think most do not deserve their job.

    This lecture on angles triggered a question for me. I never thought of why 360 degrees in the circle. Why not another number?? i just accepted 360, after taking years of science and engineering courses. Well I looked it up in Wikipedia and found that there is historical ambiguity on its origin. Goes back to the ancient Egyptians, Greeks, etc. There does appear to be some consensus linked to the time of revolution of the sun around the planet, chosen as 24 units, where 360 is convenient mathematical number related to it. I suggest reading it. Quite interesting.
