@CoolsBreeze 4 года назад

It's mind boggling how some great people can make chemistry so simple and straightforward. And meanwhile we have these ginormous textbooks and professors that use all kinds of symbols, texts calculations and more symbols from like Area 51 to explain 1st year chemistry. You can tell right away who're the good teachers and who're the bad ones.

@devinmorrisson1750 2 года назад

I’m here because the past 2 weeks my physics “teacher” has literally just written equation after equation with 0 explanation or conceptual examples. 5 minutes of this video on 2x and I’m ready for the test today lol

@AllTheButtons87 Год назад

I am in general chemistry with the lecture online and the lab on site. It has been tough because the methods my teacher uses leaves me seeking other sources (such as this one) to effectively learn chemistry. It has been time consuming and difficult with the text book being so wordy and not giving the work outs for the math involved. I have found tutoring and this channel to be the absolute most helpful ways to learn. I am so grateful that these videos are here to watch and replay to learn! Thank you so much!

@smortypi 5 лет назад

if you're more math oriented/have taken precalc, take a close look at this (and balancing equations, and redox, and so much other shit)...it's all linear algebra/matrix algebra/systems of linear equations. If you're good with matrices or want a more rigorous way to go about solving these, you can balance anything like this using matrices, row reduction, and finding the determinant. (figured that one out on my final by complete accident when I decided "fuck it". It worked.)
