CALLING ALL ENGINEERS, CHEMISTS, STATISTICIANS, EARTH SCIENTISTS

ITT: We discuss plausible, economically viable solutions to tropospheric warming and ocean acidification.

The two most popular flavors are solar radiation management (SRM) and carbon dioxide removal (CDR).

CDR my be required for curbing ocean pH and the jury is out on iron fertilization. The impact on marine fauna has already been substantial.

What is the purest field?

Mathematics? What about Philosophy?
76 posts and 7 images submitted.
>>
Psychology
>>
philosophy (hard to say, very broad and varied, only builds on itself)

mathematics

physics

In that order, IIRC mathematics had to be invented to do certain physics re: quantam mechanics, but ignoring that math is based on math and philosophy is based on philosophy

everything else munroe was right-enough about
>>
I don't see how you can claim one science is purer than another. I'm not being a smart ass, you're welcome to try to explain it. The way I see it, all science rests on empirical evidence which is inherently impure. You cannot use science to prove anything. We know this thanks to philosophy. So maybe philosophy is purer.

Of course math is pure. In fact, one could claim that any conjecture without proof does not fit into the category of math at all.

ITT: how would you go about presenting physics in an appealing way to a 13-14 years old girl?

The thing is that my aunt asked me to lecture my 13-14 years old cousin for about 1 hour on physics. Strangely enough from what I gathered the purpose of this is not for me to tutor her on what she's struggling on / studying currently, but simply to present physics in an appealing way, to spur her to study it properly herself.

Hello /sci/ and /adv/. I have a question regarding Alprazolam. I mother takes 1.6g a day for a year now. I've been wondering what you think of this dosage and length.
My other question is she lives in a high stress environment, stress involves from her personality and her anxiety/depression. She works as a teacher. Last year her mother died and I had an incident with my school which caused her distress.The family is very dysfunctional and very spread apart. I've been wondering what the best possible scenario would be for her and what I could do.

Do you think if she were to spend some time alone she would recover?

A lot of the stress comes from the house. The screaming, finances etc. My father has no relation with my mother yet they live in the same house to raise me.

My mother is also stubborn to were she tends to not listen to her doctors. She was told to be hospitalized until she recovers but ignored this, a few weeks later she had an anxiety attack while driving.

Is her spending alone time a proper solution or is it just going to isolate her?

>1.6g
mg, you mean? 1.6g is pretty much insta-death
>>
>>8583674
you can become tolerant to benzodiazepines and then have to raise the dose to ridiculous amounts to compensate, there are stories of doctors on 1000mg or higher yes

I have no idea if its possible for these people to recover, in theory yes if the dose were slowly tapered down, but f irst she would need to be hospitalized and put on longer-acting benzodiazepines and slowly tapered down in a comfortable WATCHED setting because even lowering the dose too much can lead to DEATH. via convulsions, heart attacks, blood pressure spikes, etc

Actual death, benzo withdrawal is no joke.
>>
If you are in the US I will actually fight both the MD and pharmacist. You're actually telling me they are keeping her on a super high dose of benzo's without shifting to a longer acting alternative? Where are the other medications for depression and anxiety? How fucking long did they watch her ramp up to 1.6g a day, at that point it's almost gaurenteed for her to seize when being tapered off. Your mom is on more Xanax than most people who have a debilitating addiction to it.

Why is it whenever this topic comes up people assume alien virus are compatible with earth biology enough to be a threat?

You would think an alien virus would have an evolutionary path divergent enough from earth life that alien viral infections are a total nonissue.
Earth life all came from the same place but earth virus still don't have the ability to leap across lifeforms and infect everything.

So why do people believe that an alien virus is a threat to humanity any more than, say, some extremophile bacteria/virus from earth?

I legitimately can't understand. Convergent evolution means that potential aliens would likely even share the same DNA and cell structures as earth life or something that earth and alien viral forms can exploit interchangeably? Really hard to believe considering that it doesn't work that way for earth life, which are extremely similar on those levels.

I've thought this for years and everyone I talked to about it to just said "It's still a virus." There are viruses and diseases only certain animals can get because those viruses evolved to infect those animals. I can't imagine a virus from another world being adaptable enough to be a threat to us considering how different we would be from the species of its world.
>>
If the other life forms are carbon based, they probably have some kind of virus that could affect us, or other earth animals. Not necessarily saying it's going to kill us, because obviously it's not designed to do that, but it could infect us and mutate into something that could. Or not. It's all a toss up anyway.
>>
>>8582939
>carbon based

cell based would make more sense
also
if we ever encountered some kind of "universal" extraterestiall virus it could be very dangerous for all earth life

I found this written in the back of an old Math book today:
[math] \displaystyle \pi \approx \frac{208341}{66371}= \frac{A}{17}+ \frac{B}{47}+ \frac{C}{83}[/math]
and it appears to be within one-half part per trillion of the actual value. Find the values of A, B, and C, if you're hard enough.

I don't know. The apex predators of the time were not dinosaur-tier, but they were no laughing matter either. The problem is that we don't know how fast or strong these things were, nor do we know how common they would have been. It's possible to spend three days in the wilderness without running into a big predator like a big cat or something, so I think this would be largely up to luck. Also, I believe that if I were able to see the predator coming, that I would be able to escape because humans are excellent runners and judging by their bodies these amphibians were probably not great at running long distances. However, if they attacked while I was asleep, they could win. So to answer your question: maybe, I think survival is not out of the question, but death is a distinct possibility.

They're not worth shit, they don't do shit. If you're new to collecting rocks/minerals then you could make them nice paperweights. If you don't like the way they look they could be used to send a message to your rivals through their windows.

Carbon monoxide causes violent convulsions though, doesn't it? That's not particularly safer than a nitrogen exit bag. Actually, it's way worse.

Easiest in what way? Painless? Cheapest? Requiring the fewest materials?

In all honesty though, you should call the suicide hotline. At least give it a shot before giving it all up.

Saw someone talk about this shit in another thread. What would it take to make a warp drive and how effective would it be? (All in theory and hypothesis of course). How can an object warp space enough to "propel" it forward without creating a field of gravity that could possibly crush it? How would it "create" gravity out of nowhere?
