Water is in one of three states: liquid, gas, solid. It has to be one of those. Where does the margin come from?

You're phrasing that like you're unaware you can keep heating stean after boiling it. Steam can be 100C at 1atm, it can be 125C at 1atm, it can be 500C at 1atm.

The autoclave does not superheat steam.

So if, say, you were completely irradiated - every atom of your being - and fully repaired, would you still be 'you'? /Is that a transporter energizing I hear?

A buddhist would tell you that a person is not an object, but a process, that consists of 5 aggregates, of which only one is the body. So the objection here is to the use of the word 'you'.

Probably frowned on to bring in food stuff and make it in a bio lab.

This makes sense. Even if you're not going to drink the tea in the office, even the appearance of making food in a lab space might well be enough hassle that it's easier to just bring sampling equipment home.

Testing foodstuffs can't be all that unusual in a biolab.

Okay. Now we're back at the original unanswered question, which is why it's doing it that way.

Is the pressure helping directly? Why not use a heater; is dangerous levels of pressure easier than an extra heating element?

There's no way 7 in 10 people were prescribed antibiotics in 2024. This looks like a simple and egregious misinterpretation of the data, which seem to be all too common. I could believe there were 700 prescriptions given in the US per 1000 people in the US population. But many of those would be repeats to the same smaller number of people. I still would say there's way too much antiobiotic use - every time doctors ha…

This would be my read. Hell - my children just this year would have counted for 10+ doses (my daughter 6 all by herself for a series of severe ear infections).

Yea that's another good point. Luckily my kids haven't had troubles with ear infections, but my sister did growing up. It like 3 or 4 times a year almost every year in elementary school and halfway through middle school that she had multiple that she needed to go antibiotics.

it’s a loose usage. necessary but not sufficient type of thing. if all your DNA instantly disintegrated, the process ends quickly, you are not you in many senses of the word. to preserve the artifact of DNA is to ensure (some of) the process continues uninterrupted; at least a few major failure modes of “the end of you” are mitigated. but gotta love me some Buddhist pedantry y’all can spar with the best

When you raise the pressure the boiling point of water increases which makes steam which is hotter than 100C. This is not 'superheated' because it is still at the boiling point (which is raised by pressure). This will condense on things inside the autoclave and dump the its heat into the thing killing anything on it. If you superheat the steam it is just as effective as air, which is to say not very. If you want to know more than that, you need to ask someone else, because that's about the extent of my knowledge.

Okay so the answer to my first question of "if we want it to be steam" is "not particularly, letting it condense is good".

It took some roundabouts but we got there. Thanks for the information.

> “the end of you”

Then I will entertain you with another Buddhist objection - there is also no "end" since the conditioned "you" exists in the beginningless, endless cycle of samsara, while the unconditioned you (Nibbana) is unborn, unbecome, unmade, unfabricated.
