Because my daughter is alive in my brain from microsecond to microsecond...

It must've been renewing its molecular structure... . ..from one microsecond to the next.

So what we do is we put inside the machine a process of evolution that takes place on the microsecond time scale.

For the secondary to be imploded by the hot, radiation induced plasma surrounding it, it must remain cool for the first microsecond, i.e., it must be encased in a massive radiation (heat) shield.

Starting from one atom, the number of fissions can theoretically double a hundred times in a microsecond, which could consume all uranium or plutonium up to hundreds of tons by the hundredth link in the chain.

This takes about a millionth of a second (a microsecond), by which time the core and tamper of the bomb have expanded to plasma several meters in diameter with a temperature of tens of millions of degrees Celsius.

And as we monitor phone usage by seniors over a long period of time, down to the tenths of a microsecond, that recognition moment of whether they can figure out that person on the other end is a friend and we start talking to them immediately, or they do a lot of what's called trouble talk, where they're like, Wait, who is this?
