Nuclear Reactions, Radioactivity, Fission and Fusion

Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive, not to mention what makes nuclear fusion reactors our best hope for clean energy in the future.

I am a 66-year old retired accountant trying to fill the gaps in my knowledge of basic science. For my purpose, your videos are head and shoulders above everything else on Youtube: Clear, Concise, and Complete. Many thanks. I won't say "Please keep up the good work" because I already know you will.

I'm a physics and chemistry teacher and I be watching your videos to help explain things to my students. Thank you!

This was a good video. I can't express how satisfied I am by it. You covered everything my Professor took two weeks to explain in 14 minutes.

I had forgot everything I learned as soon as I passed out from highschool, despite having aced in the exams. By the time I finished engineering, highschool chemistry was like an unknown language to me.A couple of minutes on your videos and everything just came back to place.

I still refer your videos instead of old textbooks. Thanx a lot.

I never knew someone could be this good at teaching, explaining creating content👍
*You really set the standards high*

I'm sure you get comments like this all the time, but damn dude, you're awesome! This 14 min video offered a way better explanation than an entire semester of radioactivity courses and seminars. Thank you.

Made me love chemistry even more. Keep rockin Doc

You explain things so much simpler than my professors. I’m so thankful I found your channel!

[insanetea]

I’m a computer science student but I just find this really interesting. Way cooler than sitting in front of a screen programming all day

Humanity’s rejection of Nuclear power was a massive mistake, and the environment has payed dearly for it as we continue to rely on fossil fuels for our electricity

[ecozeek]

Great video. This explains exactly what our NGSS STEM Chem students need for a review of concepts in nuclear changes. Thank you!

[davidjohansson]

I am happy I understand decay mechanics better now. It aided me to understand geological dating processes in a more complete manner. Thank you so much!

[anonymous.youtuber]

The clarity of Dave’s explanation is stunning. 🙏🏻👍

[mariakhan]

Thank you professor Dave! These videos are perfectly concise, I didn't get the concept fully when my teacher taught this, but now it's all clear

No words to explain you u haven't a nobel in a great personality

[iamthemouse]

I wish I valued your channel more back in high school. Your videos really help to give me a better understanding of science.

Flat earthers: *hey dont forget about us we use it to explain literally everything*

[sciencelearnremember]

I like how you relate the topic to visuals and real examples so I can remember it easier.

Why have I never encountered a teacher that would give a quick summary like this before getting into the details ? It's so much more interesting to know the point of a lecture before getting deep into the details. In school it's just present the details as dull as you can. Memorization is the focus rather than understanding

[viallymboma]

I have been watching documentary about quantum and particle physics and didn't really understand everything cuz everything was explained at higher level...but this video broke everything down for me and now I understand why nuclear reaction happens and it make real sense...thanks for this video...tho old, it still gold for understanding basic knowledge
