  1. Good video! Thanks for making this video available to the general public. I especially liked your coverage of science and why it is important!

  2. The math portion of your courses are way over my understanding……..but curiously, I totally enjoy your presentations and look forward to viewing many more. I especially enjoyed your Chernobyl lecture…….thanks, Wayne

  3. Chadwick said : lets assume n exists,chargeless.Most matters interact with others by charged interactions.If n has no charge it should not see matter except nuclei,collision with which will cause deflection.-So neutrons had high range,invisible to e-s.

  4. What an enjoyable, funny and well presented lecture. This professor has really mastered his craft at delivering interesting information whist keeping it light and engaging. Thanks very much from England

  5. So I'm literally a speech therapist, and I just wanted to know more about radiation after watching the Chernobyl series, and now I think I'm hooked on this lecture? I'm not supposed to like this…why is it so interesting???

  6. I love that this class is available. My life took another path, but have always had an interest in the nuclear world. Looking forward to learning more from this course. Also work for an academic institution, and been a small part of them slowly sponsoring more open educational materials. Really hoping this trend continues and florishes.

  7. as a new mechanical engineer going into the nuclear industry in the UK, this is incredibly useful and i'm shocked and kind of embarrassed the lack of nuclear basics I know / have been exposed to!! This is extremely helpful and I'm excited to follow this course.

  8. i think the reality is that even if you teach people exactly how to make a safe nuclear power source all it will take is simple mistakes that turn it into a unsafe power source. humans no matter how much we chase perfection are incapable of perfection. a good example of this is the aerospace industry. no matter how much work we put into making flying safe we still get crashes and the only difference between nuclear science mistakes and aviation science mistakes is how big the disaster and fallout is. just like flying we will just have to always assume that only idiots will accept the risk while still keeping it just so you can turn on some lights and run a coffee machine. just like flying is electricity really that important? do we really need nuclear power just so you can waste it by charging a phone with wireless charging at less than 50% efficiency? should we even allow people to have limitless electricity if they can't remember to turn off a light at night? if a very few people can create a disaster that can outlive them and their children should we be the ones to have built it for them? i honestly believe that nuclear power can be safe but just like flying it can only be done in moderation and with people you trust or you will just end up as another statistic in some multi-billionaires lawsuit. just another faceless person in a episode of mayday air crash investigation. what i saw in this video were just a bunch of kids nodding their heads so maybe thats why America is failing in nuclear power and not the other way around.

  9. This is really awesome … and I don't normally use that word. Another good resource on understanding nuclear power – which we really need considering that nuclear is probably the only real clean energy generation method that can scale up to power the whole world.

  10. I am 57, just stumbled over this series of lectures. I feel like a fly just found the honeypot. Students can feel honored to have such a professional teacher. Thanks MIT for sharing.

  11. thank you for making this open for the public, im a collage student trying to follow along as i love nuclear physics and this course is absolutely amazing

  12. I believe Nuclear Energy is highly undervalued and under-appreciated, especially in today's energy and climate crisis. I do want to understand and get involved in Nuclear Energy this course I believe would be beneficial to understand nuclear energy and maybe look into applying with my Mechanical Engineering background. Thank you, MIT!
