Nuclear Chemistry Part 2 - Fusion and Fission: Crash Course Chemistry #39

Continuing our look at Nuclear Chemistry, Hank takes this episode to talk about Fusion and Fission. What they mean, how they work, their positives, negatives, and dangers. Plus, E=mc2, Mass Defect, and Applications of Fission and Fusion in the real world!

The internet needs more of this kind of content.

Bro... Your the reason why I'm gonna pass 11th grade chemistry, XD I wish you were my teacher, my teacher (miss roach) has no clue what she's doing, she messed up teaching us about moles (6.02*10^23) and reversed gamma, beta and alpha particles, she made alpha the strongest one and gamma the one stopped by paper.. So in short thanks for being smart bro :-)

[cammus]

4:42 "Yes, krypton is real thing". LOL I loved that line.

[keraris]

Bro, you taught me more in 10 minutes than my teacher in a double class(1h 20 minutes)! Thanks for being smart.

[WyvernApalis]

Why am I spending an hour in class barely getting this information when I can get it here in a few minutes

[CultOvPleasure]

Although I'm a microbiology/immunology and pharmacology student I've always been fascinated with the more physical chemistry. Cheers for very interesting and well presented videos. It's good to take a break from working with plasmids. Lol

[mahaliaward]

Thank you so much! This really helped clear up my conFUSION about nuclear energy

[haphuongle]

It's amazing that you can speak that fast and fluently without tongue twisting. It's sure takes a lot of rehearsing and practice.

[kevinmoore]

Hands down, one of my favorite, if not my favorite video explaining how nuclear energy works.

[spencerallbritton]

There has got to be a way to make fusion work. I think it’s an engineering problem of reaction confinement, which is why I’m doing my undergrad in Electrical Engineering and am planning on studying Plasma Physics in grad school with a focus on Nuclear Fusion. It’s in my view one of the five technologies that would be most impactful, which is why I want to dedicate my life to helping to figure it out. Love the videos John, keep them up.

[unvergebeneid]

I find it fascinating that E=mc^2 is so often associated with nuclear energy but not with say chemical energy. Those 420 tons of coal mentioned in the video, together with the O2 needed to burn it will be heavier than the CO2 and other stuff released by burning it by exactly the same amount as the mass defect of a mole of oxygen.

[andrewmd]

Amazing explanation. Its potential is enormous, we just need to use it in the right way

[kev]

Thank you so much for these courses, people like you are having a positive impact on humanity.

[kumailnaqvi]

Cmon' Hank lets stretch for Organic Chemistry before the year ends!

[sneckie]

Never expected to see Commander Shepard in a CrashCourse I love

[badgerslord]

haikus are easy
but sometimes they don't make sense

[bigboy]

I got to say, you are my favorite chem person I like watching on here. Keep up the GREAT work!

[futureDK]

Do crash course quantum physics/mechanics!

[roxycorn]

I don't think I can thank you enough for all the help you've brought. The questions at the end were the cherry on top (they were exactly what I needed). Thank you so much and please keep doing this, you're saving an entire generation with their homework and stuff :)
