is paving roads out of recycled plastic a good idea?

Fuck it why not? Ain't too different from using asphalt. Plastic doesn't really recycle.
>>
>>8873723
Looked this up and found their site: https://en.volkerwessels.com/en/projects/detail/plasticroad

It seems like they've thrown out just about every buzzword they could without actually saying anything about the roads other than "hollow plastic box". I'm not an expert on plastics or roads so I'll let others tear it to shreds. A couple things I do see:
There's no way to repair damaged road except by replacing the entire segment. Unlike Asphalt/concrete there's no way to quickly patch a damaged section of road.
They stress that the hollow part can be used to lay cables and pipes. They neglect to say how you would install and maintain those cables/pipes. Cutting open the road would require you to replace the entire segment and replacing the entire segment would require breaking (And then somehow fixing) every cable/pipe that goes under the road.

Can all the content of the human mind be derived from sense experience?

Let's say I have a mental state that has mountains as it's content (i.e. I'm thinking about mountains), very obviously the contents of this particular mental state can be derived from sense experience, after all I can apprehend mountains through the five senses.

Now, let's say I'm thinking about a golden mountain. I have never apprehended a golden mountain through the five senses, nonetheless the content of this particular mental state can be derived from sense data, from my sensible experiences of gold and mountains.

Can you come up with a mental state that has for it's content something that couldn't possibly be derived from sense data?

Mathematical objects aren't really sense data if you're inventing them from scratch and haven't seen them before. Some mathematicians will describe their vision of pi in ways that smack of a sensory experience but can't be drawn or easily described. How about four-dimensional objects? Some people can imagine them, based on math alone, even though they've never seen one. If I'm not mistaken, artists often invent colors in their imagination that have never existed, which isn't surprising given the near-infinite range of colors.

Chaos.
One would have to literally disconnect the neurons from source and allow for natural chaotic sporadification then reconnect them and hope the data is not too corrupted. Sort of like pic related.

I understand how plasma is heated in a "reactor" once it is formed, but how is it formed in the first place?

Also is there a way to take energy out of plasma using the coils around a reactor?

Not trying to start an argument about fusion being viable, just curious about how these systems are started up.

Keep squishing it around with large magnetic fields it will surely heat up

Also plasma glows infrared so you can heat up your water pipes and drive a steam turbine
>>
>>8879944

the low pressure isotopes in the chamber respond well enough to be heated? I thought the plasma was only a good enough conductor once it was a full plasma?

>statistically confirmed to be the dumbest person out of 11 people in my course
>my friend keeps saying "0.1%" in mockery, not knowing how much it hurts me

Just 1 more % would have put me in the middle of the pack (average was 85.8%), where I was expecting to end up. Why does the knowledge that I got the lowest mark bother me so much, when pretty much anything else leaves me unfazed?

It bothers you because it cracks the facade that "IQ doesn't matter if I work hard enough" and exposes the ugly, eldritch core of the human condition, which says, "Thou wilst not get something by wanting it badly enough."

How the fuck am I suppose to pull 3.6+ GPA (90%+) for engineering grad school admissions? Can someone fucking tell me?

Right now I'm at a top 10 school in 3rd year mechanical engineering. Class averages are 60-70% and I consider myself pretty smart getting 10-15% above that (80% cumulative atm). Right now, that puts me at a 2.7 GPA which automatically disqualifies me from every god damn school that's worth its shit.

What the fuck am I suppose to do? I am trying so god damn hard I cant pull fucking 100s in every god damn course when some of the most talented people who got filtered into the god damn program are barely pulling 70s

2.7 after scoring consistently above average? No curve for final grades? Either you're leaving something out or your program has a vested interest in screwing over its students.
>>
>>8879784
80% average overall, GPAs change university to university (we don't have GPA here, only %), so just using the percentage with other universities common conversions, 80% is 2.7 GPA.

Humans must consume autotrophs, their products, and/or their predators to survive, so why are we considered alive when viruses aren't? Saying that viruses aren't organisms because they have to hijack something else's reproductive system to proliferate seems illogical when we have to hijack the entire physical existence of other organisms to reproduce.

Also, just in case some retard responds with, "They aren't composed of cells so they aren't alive," I'm asking for justification of the extant criterion, not regurgitation of it. I see no functional reason to use the current definition of "alive". There's no perceivable logic.

Hey /sci/

I'm currently a cs major (and usually lurk on /g/) but I realized my passion lies in mathematics, not computers. I think I'm gonna switch but I'm a bit scared. Any math majors wanna share their stories? Tips?

Just talk to professors. Seriously. Talk to people in both departments. If you don't know who to talk to, look up a [freshman/sophomore] advisor on their websites, or email the admin secretaries or whatever for each dept.

Get an appointment and sit down and talk to them. They'll ask what classes you've taken and how well you did in them, be honest the whole way. These are people who have chosen careers or roles in which one of their duties is to help students; they want to help you (unless you try to talk to some random prof who's only interested in research, but even that's unlikely).

What's a tasteless substance that mixes well with tap water or spring water and can kill a man in either 40 minutes or 4-18 weeks or months? Can cancer be given as a virus?
How about accidents via dumb common stuff like wild berry poisoning and drinking more than 5 liters of water without taking a piss?

Alternatively what is the most painless way to die?
