I've been looking at older calculators, and it seems like a good majority of them use RPN. I've never heard of it before finding it right now. Does anyone regularly use it?
I considered using it in uni, but I didn't feel like getting reprimanded by whatever professor proved to be too much of a brainlet to understand itPN and RPN are both superior to the standard way of doing things, however
>>16180407There's an entire line of programming languages defined around RPN: stack based languages, like Factor and Forth. Forth has at least a dozen processors designed particularly for it. They use stacks instead of registers.
Is it possible to geo engineer a forest in the desert? Like mutating a tree or new ways of getting water? I mean, the saudis have the money if its actually possible
>>16180382They are transitioning to what is basically clever landscaping to retain rain from the wet season. https://www.youtube.com/watch?v=xKO7Pi5SpYY
>>16180385Bullshit. Potemkin village tier bullshit.Theres no reason to even attempt this terraforming shit. It will always be cheaper to just buy grain in international markets.Saudis dont actually have that much money and can only afford to waste so much until they fall short.
>>16180308It may be possible if the conditions that originally caused dessertification are no longer present or artificially supressed.If the conditions (arid climate) are still present you'd need a fresh waster supply. Since you don't have infinite fresh water and no topsoil you'd want to start with the most undemanding and hardy plants there are, succulents, shrubs... whatever prevents erosion, covers the ground, limits evaporation and produces organic matter. On the organic matter: Many desserts are likely devoid of many minerals too, in this case you'll have to provide the minerals. Theres concepts where wet fences can provide evaporative cooling, humidification, shading and limit windspeed. You' then probably want to include more and more increasingly complex and demanding plants that will provide additional shading and locking of moisture, prevent erosion, fix nitrogen, form deeper roots and so on.Unless the climate naturally isn't arid anymore you'll have to keep providing water artificially but it will become less through your efforts and you'll probably have to keep providing nutrients that arent available, some even after top soil has formed. But the point is that maintenance goes down as fauna gets a foothold.
>>16180308The saudis may have money, but they are so utterly devoid of talent its unreal
>>16180385Holup. If they retain water, wouldn't their underground oil be mixed with water doe
Climate scientist Stephen Schneider of NOAA in the October 1989 issue of Discover magazine admitted that climate scientists intentionally mislead the public about global warming as a means of forwarding their political goals:>Stephen Schneider of the National Center for Atmospheric Research described the scientists’ dilemma this way: >“On the one hand, as scientists, we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but—which means that we must include all the doubts, the caveats, the ifs, ands, and buts. On the other hand, we are not just scientists but human beings as well.>And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climatic change. To do that we need to get some broad-based support, to capture the public’s imagination. That, of course, entails getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This ‘double ethical bind’ we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest.”
>>16178821https://skepticalscience.com/Tree-ring-proxies-divergence-problem.htm>I am confused. THere seems to be a logic problem here. If the proxies are incorrect post 1960 or there is a divergence at one time and you don't really KNOW the cause for that divergence then how can anybody conclude that there weren't other divergences you didn't understand in the past? Just because we don't see divergence between north and south there could be something which affected tree ring data over any period of time in the past either depressing or increasing temperatures that actually ocurred. You really can't have any confidence in this proxy until you understand the cause. What if the cause is caused by droughts? What if there was a large drought over the areas north and south covered by these trees? What if there was a huge flood or volcanoes or some other co-incidence like a increase in acidification due to some bacterial or animal or plant extinction or proliferation? The point is not the specifc thing but the logic being used here which is flawed by you guys. The fact is that the "science" is still very nascent and major things like what is affecting tree ring densities and widths is not really understoof even TODAY let alone 1,000 years ago
>>16179583That's due to pollution. Try reading the whole article next time.>Temperature-induced drought stress and changes in seasonality are likely to be relevant here. Also likely to have had a role is the phenomenon of ‘Arctic dimming'. The term 'dimming' refers to reduced sunshine reaching the surface in some circumpolar regions, due to industrial aerosol pollution. Northern Hemisphere pollution tends to accumulate over the Arctic. Reduced sunshine affects photosynthesis and in return that impacts upon plant health and growth. Indeed, a 2021 paper ominously commented that the effects of Arctic aerosols on net primary production - growth - were particularly important in light of the current race to exploit natural resources north of the Arctic circle.>Indeed, as the divergence problem is widespread across high northern latitudes, there may be a large-scale explanation, possibly related to airborne pollution effects. A later study (Briffa et al. 2004) proposed that falling stratospheric ozone concentration was a possible cause of the divergence, since this observed ozone decline has been linked to an increased incidence of ultraviolet (UV-B) radiation at the ground.Did you want to try again?

Good news everyone, rice, which is possibly the world's most important agricultural crop, not only grows better under CO2 enhanced atmospheric conditions, it also becomes more disease resistant when atmospheric CO2 is increased. >Effects of elevated CO2 on resistant and susceptible rice cultivar and its primary host, brown planthopperhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC8076292/>The elevated CO2 (eCO2) has positive response on plant growth and negative response on insect pests. As a contemplation, the feeding pattern of the brown plant hopper, Nilaparvata lugens Stål on susceptible and resistant rice cultivars and their growth rates exposed to eCO2 conditions were analyzed. The eCO2 treatment showed significant differences in percentage of emergence and rice biomass that were consistent across the rice cultivars, when compared to the ambient conditions. Similarly, increase in carbon and decrese in nitrogen ratio of leaves and alterations in defensive peroxidase enzyme levels were observed, but was non‐linear among the cultivars tested. Lower survivorship and nutritional indices of N. lugens were observed in conditions of eCO2 levels over ambient conditions. Results were nonlinear in manner. We conclude that the plant carbon accumulation increased due to eCO2, causing physiological changes that decreased nitrogen content. Similarly, eCO2 increased insect feeding, and did alter other variables such as their biology or reproduction.

Why do people say GPT has passed the Turing test?

What was your favorite course that you took in undergrad /sci/?For me it was thermodynamics, I was finally glad to do something other than Mech and Electromagnetism.
>>16179485Control theory, it was the first course where the profesor shared any real life expirence. It was nice to listen to him describe his work in asian factories, not boring "Id like to buy f '(x) bananas". By the end of the course I had strong desire to use pid loop in something stupid but Ive yet to achieve it.
>>16179485Either Differential geometry or the course I took on financial mathematics. The former I learnt alot about semi-Riemannian manifolds that I knew nothing about before, and in the latter I was introduced to Stochastics.
>>16179485none. I didn't enjoy any course. Choosing a STEM degree was the worse decision in my entire life.
>>16179485Mechanics. I had a hard time with the mathematics in my intro courses, a lot of the time it felt like the shit we were introducing was just needlessly complicating things, or coming out of nowhere.Mechanics was the point where it suddenly all clicked that we jump through all these hoops of redefining coordinates, or reformatting problems to take a particular form, and so on is just because it turns otherwise unsolvable (or at least annoying to solve) problems and turns them into solvable (or at least slightly *less* annoying to solve) problems.

What is the scientific cause for population decline? Is it biological? A quality of life issue?
>>16178076Children are smelly and they make a lot of noise.
>>16178076>>16178078>Personally: Why would I ? Why would I sentence someone else to life ? Life in thie world, under those conditions, with this future ? I used to want kids.This is more on the nose than it should be. I think young adults are "postphoning" children, basically procrastinating forever, they don't know it yet, because the conditions aren't what they expected. We're sold this responsibility that when you raise a child they need to have it better than you did, because thats what the previous generation's goal was. All I see are sky high home prices, sky high cost of college, if I raised a kid it would be broke city. Sure it's not the great depression, but I'm so cynic about getting my money's worth. Everyone realizes college is a racket now. Also everyone hates our culture whether they admit it or not. No one would choose to be a child today. Social media is cancer and you'd be doomed to a looney tunes world view.
>>16178076I don't believe in life beyond myself and I have never had any interest in having children. And no one in my personal life (most importantly, myself) has ever exerted even the slightest social pressure on me to do so.If I have the good fortune to become old and gray, and if I have the bad fortune to start failing and I'm put into a home where the black staff abuse me and no one to advocate for me, then I'll cross that bridge when I come to it. But what I won't do is to play the game of life.
>>16178572>>16178223I feel personally attacked. I'm seriously considering finally cutting the cable cord, and replacing it not with netflix, or with any other streaming garbage, but rather with nothing.

I even watched the original Andromeda Strain recently, which holds up very well and is interesting to re-watch post-covid.
>>16178076why would people want to have children when their national heritage is being given away to brown retards, they're convinced the world will end due to climate change, and their government is transparently corrupt and evil? millenials and zoomers believe that nothing good will ever happen in their lifetimes
