Nuclear Physics in 3D (



A 3D project I made in school. For the record: This is not designed to be instructional. This is all made up because I needed something easy to model for a final project that I had 3 days to do. There was no reasearch involved. I know NOTHING about nuclear physics. Stop sending me angry comments and messages.

    if you made that bomb animation yourself u deserve a medal
    its so much better than that other crap
    they try to make it cool but they go to far and put too much of "what they THINK" it looks like
    out of shape and stuff

    this simple little animation shown here
    is all u need to get a cool special effect

    behold! the most difficult college degree in the history of mankind, if you got Ph.D level in this, your momma must be proud of yah! I like nuclear and mushroom clouds and bombs before but after knowing that theres thousands of math involved i backed out and choose BSCS(Bachelor of Science in Computer Science) instead coz i HATE math a lot. I mean who disagree? this is the hardest shit ever!

    please do more reaserch on this topic before making a video
    there weer a lot of critical errors in this video : L

    Gamma is alot stronger than radio wave still, it's in wave form 😛

    @Sindross its spelled partiCLE, gammaS(wtf ?) are higly energetized photons :), gamma RAYS on the other hand are ELECTROMAGNETIC waves! Learn your terminology ffs !

    Gamma particles do not cause fission, it is stray neutrons!

    Is nuclear fission found in nature aside from the first atomic bombs and nuclear power plants?

    @lionsforlyons Well, I am not sure about intelligent, but you did ask the right person as I am a PhD student in nuclear engineering (albeit my specific field is fusion). This question is a little more complicated than it seems. But, the short answer is "yes," but in quotes, because it depends on exactly how you want to crash them into each other.

    I am sending you a message on youtube that explains. I wrote too much to fit into several comments.

    "I know NOTHING about nuclear physics. Stop sending me angry comments and messages."


    Just a few things: alpha decay kicks 2 neutrons and 2 protons; 235-U has 2 decay modes: alpha and spontaneous fission, the A far more likely than SF. Induced fission is the result of a neutron absorption. Fission produces "fast" neutrons, which are unlikely to fission further U-235 atoms. In a reactor, this is solved by slowing down the neutrons. In a bomb, they enrich the U-235 and use a lot of it.

    To addend, it can be from 1-20%, depending on the weapon design. Efficiencies can't get much better than that because while the weapon is fissioning, it's heating up, and very quickly becoming non-critical (criticality is the point at which each fission results in another fission) due to lowered density (fewer atoms per inch of neutron path means the neutron is less likely to be absorbed).

    wow, so easy to understand.

    Just to clarify your video:

    thermal (slow) neutrons are almost always responsible for inducing a fission.
    However, what you are saying is that uranium will decay throwing out a particle that will induce another fission. Yes uranium does decay, and yes it does throw out a piece of itself. But its half life is something like 704 million years. So this really doesnt happen that often. Also, you have shown that a deuterium nucleus is emitted. this is false. Uranium-235 decays via alpha emission

  16. kyle3420

    January 27, 2011 at 12:57 am

    @kyle3420 turning the uranium-235 nucleus into a thorium-231 nucleus (close SpaceTime4D, u just forgot that 231 is the mass number ie. 231 + 4 = 235) . Alpha particles are the nucleus of a helium nucleus, not a gamma which you have explained. but i digress. essintially what happens in a nuclear fission is the incoming neutron is slow enough (often called a thermal neutron) to interact with the uranium nucleus, causing it to split into two daughter products and somewhere between 2 – 5 neutrons

  17. kyle3420

    January 27, 2011 at 1:10 am

    @kyle3420 these neutrons are what cause new reactions to occur. Its not a natural process for uranium to fission on its own. The idea is that uranium is a fissionable material, meaning you can cause it to fission. But without a source of neutrons to interact with the nucleus, a quantity of uranium-235 will just sit there and eventually decay away until there is none left.
    so anyways, i gave thumbs up cuz the graphics were cool. My hope is that you will read this and learn something new lol

    Also, nuclei rarely fission into 2 identical parts.

  19. kyle3420

    February 6, 2011 at 5:33 am

    @Blakut actually, if you look at the chart of the nuclides, it gives fission yeild of all the possible fission products for U-233, U-235, and Pu-239. If you consider the probability as a function of atomic mass, then all 3 will produce a double-bell curve shaped graph
    ie. there is a higher chance for two fragments to be very different in mass

    Is nuclear physics the same as molecular physics?

  22. Mr. Lahey

    April 13, 2011 at 1:17 am

    if the uranium does not reach critical mass is there still a chance of it exploding? if so is it to the same extent as other famous nuclear explosions(ex. the ones dropped on japan in the 1940's)

  23. mbishop94479

    May 5, 2011 at 8:41 pm

    And that is splitting the atom.

  24. Vrej Egon Spengler

    July 9, 2011 at 12:52 pm

    @kyle3420 Not even the graphics is right. It was showing a proton-neutron hitting the nucleus. Thumbs down.

  25. kyle3420

    July 9, 2011 at 4:27 pm

    @vmelkon lol I know.. its called a deuteron actually, as opposed to deuterium. But ya, clearly this is not a good representation of nuclear fission at all!

    You have this wrong. You said uranium atoms collide. Thats not true.

  27. Quantum Grizzly

    August 29, 2011 at 6:42 pm

    Sorry dude, you've got a proton atom stuck to your neutron atom flying into the uranium. The proton would therefore be positively charged and would be repelled from the positively charged uranium. All you need is the neutron to de-stabilize the uranium.

  28. Ask a Physicist

    October 30, 2011 at 12:01 am

    I'd say this is essentially correct, except that it shows Plutonium rather than Uranium (Uranium's half-life is too long to allow it to self initiate fusion). So yeah, great work.

    Would you mind if I used this in my next video, with due credit of course.

  29. SpectatorAlius

    November 25, 2011 at 6:51 am

    @nlydeen Wrong. Uranium is an alpha emitter. But by spontaneous fission, it also emits neutrons and gamma rays. It is the neutrons that cause a chain-reaction of fission releasing energy for either a reactor or a bomb. And the neutron initiator is NOT necessary for the reaction. Just helpful in some bomb designs.

  30. SpectatorAlius

    November 25, 2011 at 6:52 am

    As others have alrdy commented, the physics is simply wrong, both in the animation and the narration. So wrong, it is an 'epic' fail.

  31. SpectatorAlius

    November 25, 2011 at 6:54 am

    @ASKaPHYSICIST No, it is not "essentially correct". Not even close. It shows deuterons leaving uranium nuclei, when in fact they emit no deuterons. And then the narration talks about gamma rays, which do NOT cause fission: it is (mostly thermal) neutrons that cause fission.

    You have had a good try here and the graphics are good but factually wrong, I wish I could make animation like that. You have the physics totally wrong. Take it off you tube or put a notice on to say it’s wrong, someone may refer to it for their home work.

  33. BloodyItalian327

    That could not be more wrong

    @Caligirlvanessa I have to ask who taught you physics because all that info is wrong.

    Incorrect, its neutrons that split uranium, not gamma particles

What if CRISPR could not only treat disease, but detect it too?




Omar Abudayyeh, a MD/PhD student at the Broad Institute, is part of a team working on a new application for CRISPR technology. Rather than using it to edit genomes, as it has been used in the past, the team is using the technology to detect viruses, bacteria, and cancer at attomolar levels, allowing for highly accurate diagnosis with small amounts of sample. Check out Omar’s 2017 TEDMED Hive Talk to learn more about how this simple and inexpensive diagnostic tool has the potential to make a big impact.
