| an energy need to make the antiproton? Posted: 11 Oct 2020 07:13 AM PDT I heard the minimum energy to make a antiproton is about 5.6GeV, but I can't find out how this calculated. (or is this wrong?) If that's fact, the proton-antiproton pair annihilation reaction makes about 1.8GeV so we can't get energy with this reaction theoretically? Or if we make many antiprotons, can the average energy required to make one antiproton be less than 1.8GeV? thanks in advance. [link] [comments]  |

| Posted: 10 Oct 2020 08:08 PM PDT I saw a post recently about island foxes in California which led me to their Wikipedia page. On the page I noticed that were classified under the genus Urocyon instead of Vulpes, which is what I'd assumed all foxes were. This led me to the Wikipedia page for the genus Vulpes which are "true foxes" due to the fact they belong to a proper clade which as I understand means they can be traced to a common ancestor. On top of this I see there are a bunch of other fox genus's outside of vulpes. So my question is: What defines a fox? Outside of Vulpes are they just canids that share common physical traits? The thing I'm mainly interested in is: How much of a difference is there between true foxes, other foxes and other canid genus's? Like evolutionarily is an island fox closer to a red fox than a jackel or something? Or is it just convergent evolution and they're being named for their physical traits? [link] [comments]  |

| Does air separate in an enclosed container when you swing it around? Posted: 09 Oct 2020 04:15 PM PDT My question is about separating carbon from the air. If carbon dioxide is 1.5 heavier than the rest of the air around us, why can't we enclose it in a bucket and swing it around until it separates, then pump it out of the separated segment of the bucket with the CO2 in it?
