Arithmetic underflow is not a bad explanation.

How you interpret is that it's pop science misinterpretation. Temperature is necessarily defined for systems in equilibrium. Systems with "negative T" aren't in equilibrium hence T isn't strictly defined.

So, what do we mean by neg T? Solutions to Boltzmann's distribution for population inversion (more electrons, say, in an excited state than the ground state).

Usually, the hotter something is, the more excited states are occupied; but in equilibrium there are always more occupied ground states.

So "hotter than any positive T" refers to "negative T"s having more excited states than positive T

I used to live in Rome in the late 90s. As many as tourists as there were, and there were many, the volume must have doubled in twenty years.

Last time I visited, I felt an overwhelming anxiety that Rome didn't exist anymore. Instead I was walking through an amusement park shaped like it.

Friends I spoke to, who live in the Alban Hills, told me they'd stopped going to Rome 10 years earlier. Which is insane because she can trace her family in Rome proper to the 16th century.

Why would it matter? Its not food.

Its not obvious (to me) that they need to rest. They're small enough not to need it.

The energy to fly those distances, however...

This was to be expected. Boeing is vital to national security not because of the aircraft it makes, but the supply chains it sustains.

As long as the USD has any value, Boeing will be kept alive.

If Boeing is so vital they can nationalize it and place actual officials in charge. There's no legitimate reason not to yank the current suits out and throw them in a neglected muddy pit.

I'm not going to argue for or against nationalization; I'm just pointing out why Boeing will be shielded from reality by our government

If it is vital to national security -- not disagreeing there -- it is paramount for everything and everyone to be investigated. You want the defense of NATO and the U.S. to be in the hands of people that can not deliver a plane?

Time for heads to drop and roll, and FBI (or any applicable agency, including DoD) to do a cleanup. That ideally should happen via the Courts too, but placing this under the rug is like inviting known enemies to utilize this weakness.

TBF only one NATO member is averse to buying airbus/BAE/Leonardo manufactured stuff.

it's not like US departments can't function with shit placed "under the rug" or anything...

:p

They should let it go bankrupt and nationalize it like we should have done with banks

They didn't. They bailed out the banks and let the managers keep their bonus

that was sarcasm. hence the :p

SVB was cleaned up amazingly well.

Isn't that what the big *nix vendors said about GNU/Linux - the software stack is too sophisticated to replace - in the early 2000s?

To this day I prefer to work on my Fuel than any other machine. But it's still dead.

Not only that, but the thermal stress of pouring molten iron on wet, cold and cracked stone.... call me skeptical

Thank you. I was extremely skeptical that they used molten iron.
