  • Gluons do not have a half life?

    Remember that they DO make an exchange - Gluons have color charge - red, green and blue. QCD is the magical realm of color charge.

    The hardest part for quantum anything is grasping the “probability aspect” means spontaneous things can happen. In the case of QCD, as you put energy into separating quarks it becomes infinitely more likely to pull particles out of the vacuum than to separate them.

    QCD is involved in fusion in a similar way - two protons will oppose each other with infinitely more force the closer they get because their charges are repulsive. The faster two protons are flung at eachother, the probability of the quarks binding increases.



  • Can you imagine being those antelope being hunted by early human ancestors -

    “Ok, bob, we just bolted at 40mph for a minute or so, they’re not going to find us again.”

    “Clarice, you said that the last 8 times and they still showed up! They’re unnatural! They just keep following and following us! Alex smashed his shin that last run, and I don’t know how many more times I can run myself! We’re doomed Clarice! Doomed!”


  • Strong force is the same.

    I don’t know if it’s shorter than the weak force, but you gotta be in an atom’s nucleus to experience it

    Edit: i just realized I may have confused people - strong force has a limited distance, not that it’s because they decay.

    Edit 2: If i ever got a PhD or master’s even in Physics, id probably write a book on how “The Universe Demands Laziness.” Because pretty much everything in physics ends up with a system taking shortcuts to save a little bit of energy.


  • I get that part, it’s still the reaction I can’t wrap my head around mainly because I don’t understand how chemistry is any different than alchemy.

    I know that lithium itself doesnt fuse to create He+T+D, and I know it can’t undergo fission. Since lithium isn’t left over, and lithium-6 and 7 are stable, does that mean the neutron with extremely high kinetic energy really knocks like two of the LiD mokecules into each other, causing dueterium -dueterium fusion resulting in He4, and the Li6 gets more neutrons that for it to be come unstable enough to decay into tritium or deuterium?


  • I mean if we really want to be technically accurate here, the lithium is just a moderater for the hydrogen isotopes to fuse.

    But for me it gets fuzzy when looking at the reaction.

    LiD is 4 protons, 8 neutrons. Add a new neutron, and bam, you have 4 protons and 9 neutrons. But that’s where it gets weird to me. The lithium needs to decay or something into a tritium and dueterium which forces the tritium to fuse with the existing dueterium in the LiD molecule? Clearly the neutron has enough energy to transfer into one of the atoms to increase the chance of tunneling actually occuring.


  • Well, at least they can see the baby steps that way I guess.

    But I’ve always wondered if I’m actually terrible at my job or if PMPs, Scrum Masters, Management, etc, can’t actually fathom that I have absolutely no way to roughly estimate how long something can possibly take that ive never done before, and I have no evidence someone else has done it before.

    When I was younger I got so frustrated with it I asked if anyone else on the team wanted to do it instead, and there was a resounding no, but it’s feasible so you should keep at it. And eventually I get it working but the whole time it’s demoralizing with the amount of “why are you not done?”

    And now I just give the exact details that goes straight over everyone’s heads anyway and ask if they need me to switch my priorities.
