There is nothing else like Khan Academy out there for improving your academic skills. They are cutting edge for learning.

Sal is amazing. So is chemistry. I really really wish my school teacher could teach chemistry like this. Unfortunately, he didn't and the chemistry class for me turned out to be all about memorising the periodic table, drawing the structure of all molecules. Never thinking about why and how. I then became a computer science engineer. At the age of 36, which is right now, I realise my real passion is in chemistry.

For all the students who are reading this, sometimes the teacher is just not good and please try to learn from somewhere else. Don't lose your curiosity about the world. I lost it when I was so young and I want to find it back right now.

Wow, I have a doctorate from Cornell, but never had a teacher like this.
This guy is EXCELLENT.
I'm hooked.

I have doctorate degree in Chemistry from Duke University and never had any teacher who can explain like Sal. Our students are very blessed.

Thanks Khan Academy! Wish I had this series when I was in school, would have helped so much and inspired so many interest i came upon naturally.
Glad this is out there for the interested kids today!

After reading the comments, I feel so blessed I watched this video before starting to learn actual chemistry.

Studying chemistry for years & now it makes sense

My 10yo has been using KA for several years and is currently using their Coding, 4th Grade Math and Grammar lessons. My 6yo uses their Khan Academy Kids app and their 2nd Grade Math lessons. I pull from KA's World History and Science lessons to teach both of my youngest boys together. They both love studying Space and their queries have lead us to needing vids/lessons about chemistry. I knew I could look to KA to teach complex concepts in a clear and interesting way, so here I am...adding this vid to my lesson plans at 2am *heh*

Chemistry is so easy if this is the kind of professors we have.

[greenlifesaves]

Thats a motivational video, even though i gone through medical studies, now feels important to study Chemistry in deep to understand basics which doctors cannot explain

[Jusscarool]

In my previous school the only subject we covered in science was biology Makin me very behind in both chemistry and physics, This is really helpful tnx. (I'm 14 and about to start my GCSEs)😢

[armybomb]

thank you. I'm not even out of elementary school, and I'm studying to become a chemical engineer. this helped me understand what chemistry means thank you!

[hifiunicorn]

This was a really helpful video in understanding what the essence of chemistry is. You really put it into perspective for me when you said that even though we haven't figured it all out, we can still make use of the functional aspects of math and physics and use it to explain things in our universe. Great video!

I'm trying to find a new hobby for the summer and I always wanted to understand chemistry, so here we are

[amss]

I am in the military about to undertake my A levels years after I left school and I didn’t have YouTube etc when I was a youth so thanks Mr Khan for giving me this chance to improve my learning

[hayleyr]

Sal got me thru linear algebra and stats ten years ago and now is helping me with chemistry for vet science :) thank you

[andrewlittle]

Chemistry is the programming language of the universe!!

[jihue]

i luv khan academy we went through everything together

[americafrida]

That was awesome. I never got to take Chemistry because of leaving hi-school early due to illness. When you get ur GED's to finish it's only basics. I am hoping I just found you & you teach a class on Chemistry!

[RedabowAndBusmalis]

Always stuns me how the study of the minute blocks of matter that make up the existence we live in can be the most overlooked of the three core sciences. Always pleased to see Khan Academy bearing the flag for Chemistry, helped me get through all levels of my education and shaped me into the scientist I am today!
