Surely there are others in perpetual AWE of this?

When a nuclear bomb is detonated, three neutrons that formerly did not exist are created*; surely from energy, that is, energy in the E =mc2 kind of way.

* portions of the article you'll go to if you click that link:

"The...power of atomic weapons derives from a sudden release of energy produced by splitting the nuclei of the fissile elements making up the bombs' core...

 ...The isotopes uranium-235 and plutonium-239 were selected by the atomic scientists because they readily undergo fission. Fission occurs when a neutron strikes the nucleus of either isotope, splitting the nucleus into fragments and releasing a tremendous amount of energy. The fission process becomes self-sustaining as neutrons produced by the splitting of atom strike nearby nuclei and produce more fission. This is known as a chain reaction and is what causes an atomic explosion.

 When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons** and some binding energy. Two neutrons do not continue the reaction because they are lost or absorbed by a uranium-238 atom. However, one neutron does collide with an atom of uranium-235, which then fissions and releases two neutrons and some binding energy. Both of those neutrons collide with uranium-235 atoms, each of which fission and release between one and three neutrons, and so on. This causes a nuclear chain reaction..."

**emphasis added

** Since having first learned about that, perhaps during the aughts, I am always spell-bound when I think about it, in a way that can only be described as Rapture. With a capital R. It makes me wonder, how the f__k did anyone figure that out? Creating matter (neutrons) from nothing?

Octonian math will blow your mind too.

Too much for me! Can you simplify all that? Like, um, write something the "normal" way and then rewrite it the Octonian way?

{#basic-cool.gif} Did you giphy "pizza octonian awe" to get that? 

Something like that, haha.
