Is Planck length/time a valid solution to Zeno's paradox?
>>7708213
Only if the position something can occupy in space is quantized.
If it moves to some intermediate value during one of the universe's ticks, it just gets pushed to the closest open space. This would also explain why some quantum phenomena seems to have future actions affect the outcomes of prior events. If there's some sort of buffer to sort out conflicts and interactions.
It's obviously inspired by quantization error as we observe it, and probably not the case. But it doesn't reconcile Zeno's paradox.
>>7708219
does reconcile*
>>7708213
Well, a discrete space and time would sort it out, but there's no reason to assume they are described by the Planck units; they're just what we get by multiplying various fundamental constants involved in general relativity with fundamental constants involved in quantum field theory to get an idea of the scale where quantum gravity effects should be large enough to be relevant.

I'm so sad /sci/. I clearly understand the material because I missed nothing on the free-response except what I panicked and forgot to do.

I am not very good at maths. I would like a /sci/entist to explain what 10^10^30 means, or preferable write it down
http://www.purplemath.com/modules/exponent.htm
the bait, fuck back to /b/
We aren't gonna be able to write it down for you. It's a 1 with 10^30 zeros after it. That is, 1 followed by 1000000000000000000000000000000 zeros. You don't really need to think of the size of a number to work with it though.

Why does everyone have an incredibly high IQ? I'm not asking "Why is everyone incredibly smart?" but why everyone has a genius level IQ these days. Are we all just good at solving problems?
Here's a passage from a paper I was reviewing today: " I could list the great minds through the ages that had depression or anxiety and were greatly successful, but that doesn’t really make my point. The point is that someone like me, with severe depression, anxiety, and mood disorder, who also happens to (and perhaps as a result of the way my mind functions differently) have an IQ of 142 which is in the 99.7th percentile—the exact opposite of a disorder affecting cognition."
This fucking "IQ genius" can't even talk about their IQ without making a grammatically incorrect sentence.
>>7708112
IQ is overrated
>why everyone has a genius level IQ these days
Because nobody brags about having an IQ of 75.
Self-selection
The only people who talk about IQ are those with high IQ
Nobody with sub 110 IQ wants to out themselves as having such
Hi /sci/,
I'm currently working full time and I have to study after a long day's work.
Before I started at my new job I could study from 8 to 4 while fasting. I found that fasting really increased my focus.
Now, however, I can't do this and found that fasting for prolonged periods of time makes my focus worse, so I need to find a new diet pattern, and maybe a whole new diet as I currently eat lots of sugars and that can't be good for the mind.
Any suggestions? How do I maximize my mental gains?
>>7708104
Who are these seman demons?
>>7708104
I've always found that I unintentionally fast when I'm focused. You just don't think about eating when you're engaged in your studies or project or whatever you're working on.
I gained weight working somewhere where I was bored most of the time. Lost weight when I was working hard with deadlines etc. I wasn't stressed, I guess I just subconsciously thought "I have better things to do than eat".
But if you're having issues concentrating, try preparing a few healthy snacks in advance. Carrots and stuff, simple. Then whenever you feel that bit of "I don't wanna do this anymore" have that 5 minute snack, then back to work.

>The inflowing water would then evaporate quickly because of the desert climate. This way a continuous flow of water could be created if inflow and evaporation were balanced out. With this continuously flowing water hydroelectricity could be generated.
How fast does water evaporate there? I can't see how this would generate more electricity than a huge solar panel

I was hoping that this would be an experiment in which a city's population were drugged/otherwise manipulated into depression.
That should be done.

Oh boy.
See the question above.
That only works in liberal arts classes. In STEM the professor is always smarter than you
He invited me to his house in a small village over the Easter holidays and I fucked his daughter and had his wife suck me off. He only found out when I hinted at it the week after he passed my thesis.
>>7707796
I've never had a professor.
What do you do when you get stuck on a problem, /sci/? Do you have a process for moving forward if you hit a wall?
>>7707590
take a 5-10 minute break
don't think about it, don't do other problems
just get up and walk around, listen to music
then get back to it
I let it be and consider other problems. Then later a new try.
Hawaiian court throws out Thirty Meter Telescope building permit
>https://archive.is/P41N4
>Excerpts:
Hawaii's Supreme Court has ruled that the construction permit for the $1.4bn Thirty Meter Telescope (TMT) on top of Mauna Kea mountain is invalid. Construction of the telescope has been on hold since March, when hundreds of native Hawaiians and their supporters protested and prevented building crews from entering the site. The court ruling is a fresh blow to the project, with the telescope's backers now having to restart the permit process.
With a 30 m primary mirror made of 492 hexagonal segments, the TMT will be the largest and most powerful instrument on Mauna Kea, which is already home to 13 others. The TMT will sit on a plateau about 150 m below the summit – a location picked to reduce the telescope's visibility from the majority of the island.
>>7707566
In its ruling on 2 December, the court claimed that Hawaii's Board of Land and Natural Resources (BLNR) should not have approved the permit in 2011 because it failed to follow due process when awarding it. "Quite simply, the board put the cart before the horse when it issued the permit before the request for a contested case hearing was resolved and the hearing was held," the ruling notes. "Accordingly, the permit cannot stand."
The court decision now requires the TMT to go through the process again that will first involve a "contested case hearing", which must be heard first before a permit can be issued. The decision by the court will result in delays beyond the targeted 2023 construction date, although how long is currently unknown.
>>7707567
Groups opposed to the TMT's construction have, however, welcomed the decision. Kamahana Kealoha, head facilitator of Sacred Mauna Kea Hui, says the group is "elated" at the move to annul the permit, which he says has been acquired "through an immorally and unethically manipulated process that has been negligently overseen by the BLNR". "Our goal has always been to systematically secure the Mauna," Kealoha told physicsworld.com. "The revoking of the construction permit is essential for us to succeed in protecting the mountain summit and the endangered-species environment from further development by this 18-storey monstrosity."
>Apparently, locals feelings trump scientific advancement...
Kealoha adds that they now hope that TMT's backers will "see red flags and pull out". "Quite frankly, the resistance is here to stay, and we plan to see to it that the TMT is not built," he says. "This could be more costly than the $1.4bn already appropriated and, speaking for myself and my group, we will continue to make sure the TMT being built on our sacred summit is not a profitable venture for investors, as we already have."
>...because getting in the way of the progress of human knowledge has worked in the past.
This makes me want to cry. This next generation of telescopes is going to incredible, and these fuckwits can only worry about "oh no muh island".
Besides, it's not like they stopped it, only delayed. It's obviously just going to be approved anyway in a year or so.
Assuming you were in a vacuum chamber here on earth, what would be the bare minimum you could wear to be comfortable?
Obviously a space suit would be perfectly fine, although heavy.
Would something like a dry suit or a flight suit be more practical?
The U2 flight suits would probably be best.
>>7707439
A pressure suit.
If your oxygen mask isn't tight enough the air pressure will cause it to leak like 90%. If it's too tight it's gonna fucking hurt. Skin surface capillaries will dialate in reappnse to low preasure causing a slight drop in blood pressure, headaches, and possible blood clotting. Eyes will lose all moisture. This would be the absolute worst. Perpetually hyper dry eyes. They may swell because of the vacuum, and may blees becauae of the swelling plus dialated capillaries that're super close to the surface. If you get stressed, and you will like this, you won't be able to wick sweat to the atmosphere and will begin to get very hot very quickly. Good luck.
This guy has got some pretty good points. I think it is a very interesting read. Any other intellectuals agree? I read science papers once a week and it has honestly helped me really understand what is happening in this world for real. Check him out. Basically, it confirms what I know about animals and how humans are different. Smart guy. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1955772/#B21
Fuck me sideways, did he reference himself? Nine fucking times? You do realize he has next to no actual evidence here beyond conjecture right OP?
He has proof for every point, sir. Did you even read it? And referencing yourself is completly valid, you toolbox. It's peer reviewed, so what is the problem? Stop being such a fag and try to learn something.

I want to see a video of an astronaut floating around in space (just have someone in the ISS go outside) and take a plastic water bottle and open it.

2. What would happen?
