The Nucleus: Crash Course Chemistry #1

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron, and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

In high school, I was very excited to take a Chemistry class. However, a few months in, it became my least favorite class. A bunch of the more rowdy students hijacked the class and often distracted the teacher - I learnt nothing, and it showed on tests. I eventually came to dislike Chemistry, treating it as a dirty word. But now, only one video in, a decent teacher has reminded me exactly why I was so excited in the first place. Thank you, Hank!

[@MadMargaretGaming]

[@dovregubben78]

Did your school not have prerequisites for chemistry? At my high school, a student could not enroll in chemistry until they had completed algebra 1 and geometry, and could not enroll in physics until they had completed algebra 2/trigonometry. This had the effect of weeding the disruptive students out, as they were still languishing in pre-algebra or remedial arithmetic.

Fds Chan Yeah, always a good thing when math is interesting ^u^ www.d-e-f-i-n-i-t-e-l-y.com/

I finished high school few years ago and I gave up studies because there were several bunch of topics I literally couldn't understand. Went for some after school tutorials and didn't help. I felt I had properly gotten really dumb. Now studying has been on my mind and didn't know what to do and I came on KZbin to check videos out. Thank you for this amazing channel and I'm learning a lot. But please is there like a community where I can post questions and get answers.

[@whiteninjaplus5]

Im a freshmen in high school and next year im taking honors chemistry so im going to learn all i can to just breeze through that class next year.

[@DeadlyAlienInvader]

I feel like I must take a test after Everytime I watch a crash course video in order to make sure that I understood and remember what I'm being taught.

[@saisevithaa1772]

Well, Hank...you are great... You summed up weeks of chemistry cramming classes in one 10 minute video of Crash course chemistry!

[@UnchosenMountainBerry]

6:03 Ms Frizzle is there :(

[@aviezerscop401]

YAYYYYYY

[@mmaking8664]

PLEASE make biochemistry videos

[@cynicaltrash4967]

BioChem sucks just take regular Biology and then Chemistry, assuming you can. (I took Physics in 8th grade and thought BioChem was something different.)

[@cookiesarelikecream]

Cynical Trash even if it might have sucked for you, biochem is necessary for many careers especially pharmacy so I think a lot of us would find biochem videos helpful

[@liv1522]

YES!

[@lozfactor]

Do Crash Course Quantum Mechanics lol

[@tewharauwalker2081]

Yes please!

[@belgardandy]

+Jay Rad Indeed, I'd like to throw my vote in a similar direction: A general physics CC series.

[@halithegreat3240]

+Jay Rad DANGIT! I swear you read my mind because before i even clicked the video i knew i was gonna comment that

[@thebestnameever7423]

+Jay Rad that would be pretty fun but the problem is that since a lot of things in QM are only hypothetical, it might not be the best thing to teach

[@anagevorgian2800]

+Jay Rad I hope so!

[@kevinmoore2501]

I love this course. It's been a favorites playlist for a while for me. I constantly come back to re-watch this course.

[@kpaasial]

"Nucleai are Bohring". I see what you did there.

[@emmajanofsky]

I'm going into Honors Chemistry next year and I plan on watching this entire series so I can be ahead and understand everything better.

[@TheMariomario12345]

[@umarpatel3517]

I took Honors Chem as a freshman and just to give you some advice don't go beyond episode 30 in this series because then it gets more into AP chemistry stuff, unless you're planning on taking that later on. Stoichiometry is a big part of it so try focusing on that because a lot of the conversions you will be doing will rely on that. Good Luck!

[@titusbarnes8306]

+Umar Patel thx

[@michaelmacmanus]

I'm running through this course now for pure recreation; stopping, repeating lessons, and taking notes along the way. I really have to say that these are nothing short of amazing! Hank acts as a brilliant broker of knowledge between the worlds of academia and the layman. For me personally this has been as exciting and as accessible as my experiences with Brian Greene, Charles Van Doren, and Carl Sagan. The enthusiasm and humor keeps me fully engaged at a constant clip, not to mention the sharing of this information broken down into something highly digestible for the masses is downright inspiring.

[@danielascillieri9790]

Have been out of class for a long long time. Watching this as a refresher... six minutes in and I'm extremely amused! Could see myself binge watching all these videos for days. I love how the humorous references really help the concepts stick.... LOVE IT.

[@thiccdumpling5442]

"Stuff is made from atoms" - Hank Green, 2012 VVery scientific, Hank.

[@KEMOO989]

I always avoid looking at science stuff at the break time but , with this channel I spent all my break time at science episodes . which is a very good thing by the way . keep it up the guys you are the only one in the world who made science and knowledge funny and interesting

[@Phobos_Anomaly]

I saw the Magic School bus! I loved that show when I was a kid.

[@queensaharaice7376]

Ikr!! Lol

[@roxiethecockapoo1138]

You have helped me with chemistry, neuroscience, philosophy, and hopefully more to come. Thank you very much for these wonderful videos!

[@dwaynemadsen964]

The only F I received in High School. I'm 58 now, maybe Hank can help me be less dumb. Heaven help you, my Brother!

[@spudy13964]

lmao it's the middle of summer and i'm not even in school but i'm taking notes on these videos because they're so unteresting

[@InvictusByz]

"You'll have to ask a Nuclear Physicist." Wow, good thing one actually works at my school. No joke, his name is Dr. Walter Kane, and he may or may not have been involved with the Manhattan Project. I will totally ask him why an atom of Silver can't have 61 Neutrons.

[@sdc137]

dont forget to tell us what he says

[@InvictusByz]

He said "Well, 71 just isn't in balance, there would be nothing to hold it in place, it would basically get flung out. If you tried to force it in it would basically bounce off."

[@BlueCosmology]

You have a 90 year old teacher in school?

[@InvictusByz]

BlueCosmology Yes. He WAS retired, but he got bored with it so he is teaching now. Its a small school of a little less than 200 and he only has 1-2 classes.

[@leannefajardo5455]

Thank you Hank and whoever is involved behind the scenes. This is such a great help. More power!

[@ella3794]

anyone else here because they have to self study chemistry to take AP Biology

[@4_everanime440]

10 mins covered 2 hours worth of lessons I didn't understand!!! Thanks CrashCourse

[@kaitlynrendon4344]

I'm too distracted reading the comments..oops

Try to take notes it helps...i guess

[@ashvini6385]

Whoa! your videos actually keeps me stick towards the subject, no matter how much the boring topic it will be. Thank you so much Sir for your efforts. I am very much grateful to you. Blessings from India. :)

[@rockercaterrorencountered4924]

I love these videos

[@Ureyeuh]

I just learned more about chemistry in this video than I did in my first semester of chemistry in highschool. Part of that truth lies with my will to actually want to learn more, and part of it has to do with how well this was edited and produced. I'm subscribing for more education and knowledge! NOTE: The occasional restating and review of bits throughout the video and in the end made a huge difference in my ability to retain and understand the material. Thanks for that!
