Chemistry is the study of matter and energy at the scale of atoms and molecules. As the most all-embracing discipline there is, it should be at the top of everyone’s list of must-learn subjects. Unfortunately, chemistry has an undeserved reputation for difficulty and abstraction. Any subject that encompasses as many components as chemistry is going to appear complex. The beauty of delving into the study of chemistry is the discovery of how organized, logical, consistent, and powerfully predictive it becomes—if properly presented.

I am a 70 year old beginner. This video was very helpful and made the idea of studying chemistry far less scary!
-
Love the "no nonsense" style of presentation. Quiet, calm, lucid not cluttered the the mess created by media students.
-
Outstanding video: well explained, interesting, informative and superbly narrated.
-
Thank you for this. Years of college, minutes on youTube. This is great. Thank you. Opportunity for more Great Minds to manifest from watching your intellectual videos.

Nice one! It's possibly worth mentioning that anions are so called because they collect at an electrical anode; and vice versa for cations. Otherwise it's a bit confusing that cathodes are negatively charged, but cations are positively charged. Also, some chemists and many biochemists refer to an atomic mass unit as a Dalton.

I stumbled on this channel today and I decided to check out this video. Damn! you did a-lot of work to put all these together just for our understanding. I really appreciate you, and I plan to be more frequent on this channel so as to learn more from you. Kindly treat other topics on this channel.

I'm currently in the middle of the course. I took General Chemistry over twenty years ago at WVU and the professor I had was my all-time favorite. Dr. Davis reminds me a lot of him. Excellent class!

One year of not understanding chemistry in school fixed in just 30mins ❤️❤️
-
So easily explained with scientists' names and I liked the conclusion with the repetition of the material. Very professionally made, thanks a lot👍
-
Outstanding video: from basic to complex, explained in a way that anybody can understand!!!!
-
Wow, I love this, will share with my grandson. It is explained so clearly.
-
Excellent coverage for one and all of us to understand the basics of all the matter of the universe Thanks a lot

You ever wonder why kids are confused by chemistry? Well, here’s a perfect example - a cation is a POSITIVELY charged ion, and an anion is a NEGATIVELY charged ion. Simple enough, right? But then you have a cathode, a word that also starts with “c” (you can even go as far as “cat”...3 letters...similar to “cation”), which is a NEGATIVELY charged electrode, and an anode, which is a POSITIVELY charged electrode. Wouldn’t you think it would be easier to group the similar names together (regarding charge)? Cation...cathode = positive; and anion...anode = negative (or the other way around). What genius thought opposing the names of charges would be better?

Thank you for this excellent presentation.
-
My son would love this .. good stuff!
-
more please yom yom yom :) fantastic series. ty
-
Wow very good video thank you.
