No vaccine is 100% effective. This has been known since forever. This one has an efficacy of 60-80% for preventing infection (still >90% for death)), herd immunity is impossible under these circumstances. So you either get a vaccine shot, or you try your luck with a natural infection.
The latter would be a nice choice, but I guess governments don't want to be called responsible for full hospitals and mountains of dead when the free running infections affect the 10+x% of old people where the vaccine fails. The situation with vaccine is still strictly better than without.
I wonder why is that so hard to understand?
>water
And I thought it was literal poison.
>>
>>13468479
Not him.

I think controled natural infection should have been the correct strategy.
e.g. Lock down the entire country and open a few section/s so as to not overwhelm the hospitals. Once herd immunity is reached, in that section/s open the next sections.

People who have been infected don't get a second infection, it's very rare unlike the vaccines. If the population is high enough vaccinated people can still overwhelm the healthcare system. The UK is following this trend.

There's no high quality data out there that I've seen stating prior infection with WT virus prevents delta transmission more than vaccination. If you have it, please post it here.

But even if we assumed that were true, hospitals were significantly more overwhelmed in the winter in the UK and parts of the US than they are now. And even with rising case counts, this wave in the UK is fixing up to be the least deadly one. Preventing hospitalizations and deaths altogether does a lot more than just hospitalizing people piecemeal.

I want to see how many fucking protests that would cause all over the country. Note that such a lock down would have to be harder than what most countries dared to do in the last 1.5 years. This virus is too easily transmitted.

A region of several states (in this case, Oregon/Washington/California/Nevada) had skies like pic related continuously for about 2 months last year. If we go to mass solar panels for the bulk of energy production, how does the grid make it through that time without completely collapsing? Just have 2 months or so of energy storage on hand for the entire grid?

Texas, Wyoming, lioussiana. Completely independent and EXPORTS energy for the other states

Tell me again why we should not be independent.
>>
>>13468659
Because none of the other states have had blackouts that last longer than a week and greater competition means cheaper power. An HVDC grid would also help deal with the duck curve so it benefits fossil fuels too. Really the only power source than doesn't benefit is nuclear because of how expensive it is.

Fractional Distance: The Topology of the Real Number Line with Applications to the Riemann Hypothesis
https://vixra.org/abs/1906.0237
>Recent analysis has uncovered a broad swath of rarely considered real numbers called real numbers in the neighborhood of infinity. Here we extend the catalog of the rudimentary analytical properties of all real numbers by defining a set of fractional distance functions on the real number line and studying their behavior. The main results of are (1) to prove with modest axioms that some real numbers are greater than any natural number, (2) to develop a technique for taking a limit at infinity via the ordinary Cauchy definition reliant on the classical epsilon-delta formalism, and (3) to demonstrate an infinite number of non-trivial zeros of the Riemann zeta function in the neighborhood of infinity. We define numbers in the neighborhood of infinity as Cartesian products of Cauchy equivalence classes of rationals. We axiomatize the arithmetic of such numbers, prove all the operations are well-defined, and then make comparisons to the similar axioms of a complete ordered field.

Of course it's impossible to tell whether Reals exist in the physical universe, since it would be impossible to measure, that doesn't means that the ideals don't exist within an ideallic plane.

Then perhaps not so many patients would have died, since the nurses would have been more relaxed. There's no reason to have strict standards if people do things better at their own pace.

greetings /med/.
after much research, i am going to perform cryosurgery on myself and freeze off my warts with acetone cooled by dry ice.
dimethyl ether, the usual gas used in "home freezing" cans is only -25C, which is INSUFFICIENT and causes unnecessary cell damage by virtue of long exposure times. dry ice is -78C which is not as good as liquid nitrogen's -196C, but it's still pretty good.
i will report back with my success.

Sci Fi depictions of a blasterd overpolluted, overpopulated Earth bereft of natutal resources is a fear of a bygone era. It isn't likely to happen.

Our technological advancements have already pushed us beyond the points of apocalyptic Maltusian predictions. We are able to feed more people and are more efficient with our resources. We aren't running out of fossil fuels any time soon and we habe become more efficient in it's consumption and we are learning to synthesize fuels. I don't know why we are still being pusjed apocalyptic crap.

I built neural networks in octave while taking Andrew Ng's Intro to Machine Learning course, years ago. Sure, a toy algorithm doesn't seem like it can become superintelligent, but GPT-3 surprised a lot of people, in spite of working fundamentally on the same principles. There are some researchers who think the current techniques are good enough for AGI, and just throwing more parameters and compute at the thing gets us there.

The bottom line here, though, is that while it's uncertain rogue superintelligence is plausible, there is also no good reason to expect it to be impossible, while several of the leading AI researchers, like Stuart Russell, do take the threat seriously.

I’m a little dubious about the term far-transfer, but it’s certainly true that mental mechanisms honed through training for tennis can also be applied outside the sport. Predicting trajectories of objects in motion is certainly one.

Similarly, skill at skateboarding translates to snowboarding, which translates to surfing. But even in this case, the underlying mechanism being trained is an understanding of physics and balance, rather than merely some ability to learn sports.

>it’s known that memorization and recall is a process of applied intelligence, not intelligence itself. And then the process can be made more efficient through training.

Do you mean you can become more efficient at memorizing and recalling? I guess so, Spaced repetition and mnemotechnics are good examples of that
>>
>>13468537
We need to make the distinction between cognitive ability (intelligence, which does not change), and the application of cognitive ability through learned processes. Memorization and recall is a learned process, and can be improved through training. Cognitive ability is going to play a major role in how effective that training is.

Not bashing musical training though, no matter what you have to work with, music can help you use your brain more effectively.
>>
>>13468566
Yes, it’s actually alarming how much you can improve it through training. The Memory Book by Harry Lorayne is a good quick and dirty read on the topic.

But also, training memory is very similar to the “chunking” you were talking about. You’re just creating a daisy chain of mental associations, and attaching the stuff you want to be able to recall to the various nodes. Not unlike having an organized filing cabinet vs a huge pile of papers on the floor.

In fact, what’s going on isn’t that your getting better at memorizing, that stuff is up there, you’re just getting better at finding it when you want it.

Isn't it crazy to think the brain is able to learn how to use 360 degree vision! (something we didn't evolve for) and yet we somehow think you can't improve general intelligence?.

Go ahead, download that mod for quake and after a few minutes you will feel like you have used 360 degrees vision since your entire life
