What would disprove the notion of exponential technology?

I have heard it said that in order to be rational one must have at least some criterion for disproving their own beliefs.

what is exponential technology?
>>
>>8902226
The myth as it were, that all technologies will always improve as long as sufficient capital is spent.

Having spoken with my grandparents and done quite a bit of research on the history of technology, i know almost for certain that this is not the case. technology comes from exploiting natural phenomena, and given that there are only four fundamental forces in the universe, the number of exploitable natural phenomena is likely also limited and much smaller than most people would think.

I'm just looking for input on how others would falsify the hypothesis.

We don't even understand the human brain at the physical level yet so there is clearly a lot more out there.

Inspired by this big retarded object:
http://www.paoloventurella.it/global-cooling-skyscraper/

Global warming is out of control and it's too late to slow it down! There's only one solution: Cooling the Earth.

What sort of system would you, given infinite ressources, time and funding, make to cool down a planet?

Anything goes as long as it is somewhat grounded in science (no diamond-hard science required) and it does not involve reversing entropy or dumping the heat in a pocket dimension. Go wild!

How about letting nature take it's course and stop trying to prevent the climate from changing? I'm curious as to what lies underneath the ice in Antarctica. And if rising water levels are such a problem, why not modify buildings to adapt to fluctuating water levels?

i can barely imagine how much mental distress comes from being a climate change alarmist day in and day out

>>8902009
Then let's put another scenario: You've provided the world with a literally endless source of energy!
However, that also means an infinite source of waste heat! How do you solve that problem, without removing the source of said infinite energy?

>>8902011
I care little about climate alarmism. I wonder what sort of cooling system could be used on a planet-sized object. It's not like a starship where you can just slap some radiators on the side.

I've been working on a fantasy setting taking place on an Earth-like planet with an elliptical orbit that is tidally locked to its star. Naturally, there is the climate dichotomy with the night side being frozen year-round, with a tundra creeping up to the twilight band. Conversely the sub-solar point acts as the center of a scorching desert that becomes arid but livable as it approaches the twilight band.

Considering the culture that would arise should humans arise there (think 1700's technology) what effects would the unique geology have on culture? Would there be short, standard units of time like hours when there is no concept of days? What would be a rough estimate of a maximum sustainable population given the habitable landmass and turbulent weather?

>>8901393
given 1700s tech units of time would likely be arbitrary, or defined by something other than the movement of celestial objects.

the constant sunshine would make the habitable band a center for agriculture and power generation (if theyve figured out solar cells by then), and would likely be far more affluent than the frozen region or the subsolar region. humans living a bit outside the habitable band would likely adapt to the climate too. sustainable population would probably be about 500M
>>
>>8901393

Have you tried reading the many sci-fi stories that already explore this possibility? Stuff like Arthur C. Clarke's short story "The Wall of Darkness", or Larry Niven's "Known Space" series, or Jack Vance's "Big Planet" novella, or Roger Zelazny's "Jack of Shadows", or Robert J. Sawyer's " Quintaglio Ascension" Trilogy?
>>
>>8901416
I'd imagine that celestial objects could only be viewable from the night side, or the darker end of the habitable zone. You'd have a lot of people who have only heard about stars, and likewise the possibility of people who have only heard stories about the sun if they live in darker parts with little sun.

if the universe is really eternal how can it be only 14 billion years old right now?

doesn't make any sense. wouldn't it be indefinitely unlikely?

Who claims it's eternal? The discovery of expansion pretty much proves it isn't.
>>
Some time after proton decay or heat death, many many trillions of years into the future when all energy is evenly distributed and individual quanta are just surrounded by a vacuum with the next quantum of energy being so far away that the expansion of space prevents anything from ever interacting again, you may aswell say the universe has ended. If things can't change, is it really meaningful to talk about time?

in that case it is a corn starch and water which means when it is at rest the starch particles are farther away from each other and are able to flow past each other easily, when agitated the particles are packed tightly together and push the water out of the way making it seem solid

What is the science behind spirals in nature?

Why do newage and popsci fags talk about muh spirals all the time? Is there something mystical about it?

Think we've got dividing and multiplying by zero wrong, lads.

It should be:

[math]a \times 0 = a[/math]
[math]a \div 0 = a[/math]

So, the exact rules for dividing and multiplying by 1.

Because:

[math]\sqrt{a^2 + b^2} = |a|\sqrt{(\frac{b}{a})^2 + 1}[/math]

Is true for everything, except 0 under our current rules for dividing and multiplying by zero, therefore either our current rules are wrong or it just doesn't work with 0.

Can /sci/ explain why I am retarded to think the former?

Why aren't there any people nowadays who are masters of several different disciplines? Currently you only get super autists who excel in their specific niche field.

you can't be a master of several different disciplines
the best you can hope for is a niche that people consider to be part of a couple disciplines so you can call yourself several things
>>
>>8904778
Currently, humanity has gathered so much knowledge that a person won't discover more unless they dedicate their studies to a specific field. You have to be great at something, instead of okay at everything.

>>8904787
That's probably what people thought back in the day as well. There are still plenty of things to be discovered.

GPA is less important than actually having good research under your belt. 4.0 I'd only really necessary if for some reason you never did any research to compensate

I actually have ADHD so it's less like my brain goes from a slow multicore to a fast singlecore, and more like it goes from an ARM processor that randomly kills tasks to an i7 that doesn't.

>>8904029
Even if you take it every single day, at proper dosages it will take years and years to build a tolerance high enough to impact its effectiveness.
And even then, you just stop using it for a month and you're right back to where you started.

probably Seattle or Boston for different reasons

Seattle apparently gets most well read city constantly and obviously has all of the white collar industry related to computers

Boston because 2 internationally top schools are right next to each other and they have a big biotech thing going on there too

I'd probably choose Seattle because having top schools in your area doesn't mean anything since the graduates either stay cooped up in the university for grad school or they move away to a job somewhere else in the world. Everywhere else in the USA doesn't strike me as particularly intelligent. NYC has a huge financial thing and SF has software development but they definitely seem dumber and shittier anyway. Portland seems like a Seattle with less white collar jobs, same for Austin.

tfw none of these places have google fiber yet

At the end if the day, the most /sci/ city is probably not in the USA, but somewhere in Europe.
