We’ve tried lots of strategies for getting salmon over dams to their spawning grounds — fish ladders, fish elevators, fish trucks … even fish helicopters. But all of those methods are expensive and none of them are efficient.
Enter the salmon cannon.
(This reminds me of the old joke: What did the fish say when it ran into a wall? “Dam.”
Maybe they’ll have to change the punchline to “Shoot.”)
Feynman diagrams depicting the different (decay-)channels for single-top-production mechanisms. The letters refer to top quarks (t), bottom quarks (b), light quarks (q: u, d, s), W bosons (W), and gluons (g). In each case, the incoming particles are shown on the left and the outgoing particles on the right of the diagram. The circles indicate the W-t-b vertex (interaction), whose coupling strength is governed by the CKM matrix element Vtb.
You’d think for being the best choice this one would suck less
I don’t even think I’m dealing with dystopias. It’s just versions of what I see the world is now. Brazil was about then; it just happens to be that now is even more like Brazil than the world was then!
