Have you used it before? What was your experience? What does science say about the effects short and long term? Can it learn you to think better even when you are off of it? How detrimental is it to your health? Ritalin general I guess.
Also interested, have also known people to take aderall for studying.

Btw, this is OP and I am using it at the moment. I find it really effective, but I'm a little wary of the consequences of prolonged use. My GP said there can be no long term mental damage unless you abuse it (ie. snort, take too much), and as far I can tell is there is a slight edginess when first peak ends. But apart from that it's a miracle drug. I'm 25.

Stupid question, is it harder or easier?
Anyone else feel like we might genuinely, for-real be close to fusion?
It seems like all the more recent reactor projects are making tangible strides forward, and the hard problems are finally being tackled. I think we could live to see it, bros.

Here's another question.
Will it be our salvation, or a great leap toward the self annihilation of the human race?

How will we reach FTL travel without the effects of time dilation mucking it up?
Stupid singularity nigger.
>>8046456
Relativity is an issue with any mathematically plausible form of ftl, since you dont reach particularly fast velocities
>>8046463

It is frightening that we are so close to the end.
They've been saying this since the 80s, just like fusion

Hello /sci/
Given that the constraints of natural population control due to disease, famine, and other factors have largely been eradicated thanks to engineering and technological advancement: overpopulation, dwindling resources, and the destruction of the environment and reliable food and water supplies are, regardless of your political affiliation, tenable and unavoidable consequences that humanity must and will face in the next few decades. What are the most correct ethical, moral, and/or scientific solutions or approaches to this?

With remarkable cooperation and a massive increase in NASA's budget this is still a lofty and yet unattainable longer-term goal (say, twenty to fifty years until actualization), What would be a better interim placeholder?
This shouldn't come as a surprise, but do not learn economics from the internet (not talking about books you may obtain, of course), politicians or political pundits.
Economics is widely misrepresented in the media, where hugely dumbed down debates on macroeconomics from the 50-60s are still commonplace. The criticisms from "economic schools" such as the Austrians or the Post-Keynesian, which have a heavy presence online, are either misguided or completely accepted by economists. These pass an image that economics is highly ideological, where, in fact it is not, and that economics is all about macroeconomics.
What is being currently done on economics in academia has nothing to do with these debates, is highly empirical and economists "destroy" each other with skepticism (as it should be in all sciences). It also has nothing to do with what is learned in undergraduate courses, unfortunately, even though many topics could be taught to undergraduates.
If you bother to read serious economics textbooks note that these books are largely outdated and mostly stuck in the 80s and 90s. If you truly want to learn what economics is, information is spread in a lot of papers mostly from the 90s onward. Economics is young, there has been a huge shift in rigor in the 80s and 90s and it hasn't been properly compiled in textbooks yet. This is the major reason why the undergraduate courses haven't kept up, as academic papers are not as digestible by undergraduates.
The major issues in economics are that of lack external validity (many variables), lack of statistical power in macroeconomics (small samples) and unobserved variables which require imperfect methods to be estimated (the biggest one, actually). The most common result in economics, which is not published due to publication bias common in all sciences, is "you can't conclude anything", even when "intuition" says otherwise.

How do I take economics as a proper science when my cousin who is doing master at a top uni in the world asked me to do quantitative assignments for her which are just dumbed down versions of our statistical class assignments?
>>8065271
How do we take you seriously when your cousin is retarded?
If we keep zooming out to the end, what does the Universe look like?
consciousness.
isnt it eerie? i think the universe is somewhere we go when we sleep.

How do we know for sure that Earth doesn't have a twin planet opposite of the sun?
Because there are spacecraft round the back side of the Sun with side-ward looking cameras called STEREO.
>>8061749
Gravity.
because of lunar and solar eclipses.

Didnt even have time to answer the last ten so I answered them randomly. Whats the deal with the answers? Are they binary or is there a spectrum of answers?

If the Rate of Evolution is so much faster in organisms with shorter generation time,how come bacteria haven't majorly evolved in the last 100 years since we were able to observe them?
How come e.coli hasn't for example grown a flagellum,or shows other changes to the e.coli that were observed thousands of generations ago?
> trusting science

>>8065834
Because hey are quite suited for their environment.
evolution requires sufficient environmental pressure famalam.
Bacteria DOES evolve very quickly, which HAS been observed. With, believe it or not, E. coli:
