the man who decided to end german nuclear power production getting a seat in gazprom doesn’t inspire confidence in reality-based discussion of this subject

they also last decades and are cheap to run with extremely low carbon emissions

most of costs are costs of construction. french and koreans don’t seem discouraged and some plants in japan and china were built under budget. finland energy supply has large fraction of nuclear and they have extremely cheap electricity

oops all Brassica

This is why i always place all important info in Supplementary Information which is almost always free of charge. except on sciencedirect. fuck them

still 84% to go

there was a time when anthropic models would refuse any question related to medicine. not because they care that hard, mind you. it’s because that bloated startup is ran by cultists and they were worried that chatbot will come up with a bioweapon

if you do that you have bigger problems

only if you take notes

this advice is specifically about sulfuric acid. it’s denser than water, so if added to it it will sink diluting itself along the way, while also heating water around and making it float to the surface. if done opposite way, water won’t mix immediately because of large density difference so neutralizatio heat will be deposited on surface between these two boiling water and throwing acid around. this matters less with other acids because less heat is deposited, and in some cases acid is less dense than water. but if you stir the acid quickly, you can do it either way as long as you control temperature. this also is the case when you need to mix two different acids

tldr you can do whatever you want as long as you know what are you doing

e: i’ve checked and heat of dilution is greatest for sulfuric acid, liquid HF is similar per gram, gaseous HCl and HBr are half of that per mol, other common acids 5-10x less esp as aqueous solutions and not neat. also the same happens when diluting acids with other solvents, like alcohols or ethers, these might be even worse because they boil at lower temperature

technically pv panels are also heat engines. this is why they need cooling

the steam part is in the rest of hydrological cycle

i heard a story about varnish factory that failed quality checks after one old guy got fired, he was a smoker and used to spit in the main reactor. some enzyme from saliva made it shinier

it will vary, just after distillation (or RO/ion exchange) it should be closer to 7 then it goes down as carbon dioxide gets absorbed. that’s why it’s buffered everywhere where it matters

in my case the size of the system was so small they didn’t have that excuse, yet they were only ever able to get correct results after experimental data was handed over to them, zero predictive power, useless

seeing that jargon file has an extensive page on retrocomputing feels like figuring out that there were archeologists in ancient egypt

some people would tell you that we can simulate small bits of chemistry but it’s flat out wrong (i might be biased as i’ve wrangled for a year with computational chemists about results that don’t conform to reality) and even then errors are so large that’s it’s useless

and then some bozo says that biology is just complicated chemistry and chemistry is just complicated physics and we can simulate physics

curious thing is that i never hear biologists or chemists saying that, only some physicists and techbros. just trying to simulate your way out of small organic chemistry problems will make you even more hopelessly lost than you were before

maybe it introduces some critical contaminant (many such cases)
