Help me, science nerds. I suck at science. I've been wondering this for a long time. Inquiring minds need to know.

I don't want to keep a spoon in my coffee while I'm drinking it, but I'm interested in when I'm making it up (and using a hand frother to make up some foam for a pseudo cappuccino), if in that interim, after stirring in the sugar, should I keep the spoon in or take the spoon out? Which will keep the coffee hotter longer?

I think the layer of milk foam does help to retain the heat a bit, making a somewhat protective 'cloud pocket' I'm calling it. But would a spoon sitting in it while I'm doing this pull heat or retain heat?

Would you change your answer depending on the mug material? Ex: ceramic, bone china, glass, metal, plastic, paper cup. Obviously metal is far more conductive than paper and plastic, and ceramic and bone china are... what... in the middle of efficiency? I always use ceramic mugs at home.

I've tried various things to keep my one cup of coffee as hot as possible for as long as possible. I have a hotplate. It tends to burn the coffee, even on low temperatures. 176F seems to be the best temp to drink the coffee, but it burns. Lower temperatures will burn the coffee when the quantity is lower in the mug (about halfway empty; or halfway full, lol).

I also have a ceramic top/lid. I'm back to using that a lot now. I find it works the best. But, of course, you have to keep taking it on and off for every sip.

I don't use coffee makers, so there is no pot to pull from. It's too much volume of coffee. I"m sensitive to caffeine.

Anyway, any science-y thoughts or advice, I'm interested. Use all the jargon. Talk over my head,, lol. The more science, the better...

I don't have much hope for the future anymore, it feels all very bleak. I don't know if there's really a point in working hard, studying or even expecting to have a half decent future, because ai will replace almost all of us unless the tech ceos and the government wants to step in, which they won't with how they are. there's a big chance we'll all be dirt poor living horrible lives, in technofeudalist ultra conservative dictatorships, in the not all that distant future, if WW3 doesn't kill us first. the risk feels more imminent than ever. then there's climate change, and if we're dirt poor and abandonned by our governments, we're even more fucked. life will be horrible for men who aren't ultra rich already, but for women it will be even worse since i'm like 75% sure with the heritage foundation in power with their projects, and the massive brainwashing of gen z & alpha boys/men, women will be stripped of their rights completely and all the western world will follow. so i don't know if there's a point in sticking around, if on top of everything i'm going to end up as some slave to some guy who hates me.

i've always known govs were corrupted and there's lots of hidden evil in this world, but now it's so naked and blatant. everyone is becoming crazy, and we're all getting so extreme politically. i also feel like i feel this world is being operated increasingly by evil rich people who hate us and want to do everything that makes them more powerful and rich at our expense, and there's nothing we can do.

I think we're all living in the very end of an era; of peace in the west, freedom, high living standards, abundance, and human rights. I think soon, we'll be living in a horrible dystopian world none of us ever thought we'd know.

i sometimes wonder if living is worth it, if we'll all be miserable soon without escape
