what are the top unis in canada in terms of academic prestige?
>>7784711
Toronto, McGill and UBC are usually the big three iirc
also you can throw Waterloo in there for things like math/CS
>>7784711
depends on the field
I went to uoft for math and got into harvard with recommendation letters since several of my profs were so well known
ubc is pretty great too, mcgill is overrated and is more well known in canada than internationally
internationally its mostly ubc/uoft
>>7784711
dalhousie is #1 in all statistical categories
You know you get those images that try to explain gravity and it always looks someone's put something heavy on a stretched piece of fabric. When really that sloping down to centre is just a 2d representation of an effect that happens in 3 dimensions.
How come the solar system seems to fall into that 2d representation with all the planets near enough on one plane? I'd of thought that the planets would be just as likely to orbit the sun in all kinds of inclinations but they dont...
??
'cause accration of the initial dust cloud around the sun that formed everything.

I don't know how to long divide so most of that is lost on me but I did gather that they generally aren't flat... So what about the solar system that is.
What is the most beautiful branch of STEM?
Theoretical Physics
Total Synthesis
Phrenology
Is psychology really as full of shit as people say it is? Please respond only if you've had experience with the field. I've been very interested in learning a branch of science that focuses on human behavior, but there's a stigma about Psychology that makes me hesitant.

I have a light with a grounded plug that I want to use on a timer I have on hand. Problem is the timer only accepts two pronged cords. Could I use one of these cheater plugs and connect the ground tab via ring terminal to a grounded cord plugged in close by?
>>7784625
thanks, didn't see that
>>7784620
You could. Probably not safe though.
What is /sci/'s impression of the National University of Singapore? It's ranked 13 on Times ranking for engineering, better than Cornell and Rice university. Is this university legitimately good?
>literally looks like you went to U of Anus
>>7784600
I heard its ok
What if black holes are civilizations that have attempted traveling in four dimensions and it caused so much entropy it caused it to form?
>>7784583
die
Also just stating that I haven't studied physics yet so dont sperg out on me
>>7784583
What if.

Hi, /sci/
I'm not really sure if this is the right place to ask but I figure its more of a /sci/ question than a /his/ one.
I've been reading Natural History by Pliny the Elder and I'm wondering if there's any scientific validity to any of the cures mentioned.
Obviously I'm not looking to try any of them out and I also realise that something like anthrax probably can't be cured with a mixture of oak-charcoal and honey.

Why don't you just look up their uses, or lack thereof, in modern medicine? Doesn't he list hundreds of different medicines? How are we supposed to answer this question?
>>7784590
Well you guys are a clever bunch so I thought you might know a few off the top of your head that you heard about in your travels.
>>7784599
Opium. Yes it is used in modern medicine. Happy?
So /sci/ could we one day build our own universes and escape there or will the heat death of the universe fuck us over inevitably assuming we even make it that far?
>>7784462
Maybe. /thread
>>7784470
Heat death = fucked.
I need some recommendations. Trig and chem oriented.
>>7784386
I recommend the TI-86 or TI-89 ya crazy kid. Now don't reply to this thread and let it fall off the catalog.
What is the answer to this equation, not using a calculator or Google
20/2(5+5)?
Pic unrelated
20/2(5+5)
20/2(10)
10 * 10
100
(5+5)=10
20/2=10
10*10=100
>>7784355
20/2=10
10(5+5) = 50 + 50
50+50=100
Im gay
So, I'm starting to struggle with my medicine degree in the final year, I've basically spent most of my time so far playing video games and masturbating. Is there a scientific method to combat this demon?
Just don't become a NEET. Some people phase out of this well, for lack of a better word phase. I've played video games my whole life and I wonder when I will quit. You can use other less time \-consuming sources of media or get a new hobby. As for the porn situation, just go outside man.

The problem is it has become an ingrained habit, I've been doing it habitually since my early teens. For instance, if I go onto the computer to do some research, write an essay or simply check social media, I end up debasing myself with some disgusting fetishism shit because I have to look for ever more extreme forms.
You study in the library or on campus somewhere where whipping your dick out isn't an option.
Ex. I'm a grad student and when I need to study and ensure that I don't have distractions, I go to my grad student office and study there with my laptop. Studying at home is too often interrupted by masturbation marathons so I basically don't even try it anymore.
Hello /sci/
Im going to a tech college in my state for some sort of engineering. I want to talk to chemical engineers, because I think chemistry is super cool, but I got an 80 C in chemistry these last years because it is very difficult. Should i worry much? Thanks.
>>7784315
Chemical engineers don't use much chemistry. A more correct term for us would be "tube engineers."
>>7784340
Why do you say that?
>>7784341
The tube part was a bit of an exaggeration, but we really don't use a whole lot of chemistry (depending on what exactly you do, this will vary). Most of the time we work with flow rates of things, thermodynamics, reactor operations and all sorts of equilibrium stuff. The majority of us don't go anywhere near things like organic chemistry.
Does introducing heat into something make it slower or faster, why and can you give an example?
A cup of hot water moves at the same speed as a cup of cold water, 0 m/s.
>>7784203
Temperature is a measurement of the vibration of atoms, thus gradually raising the temperature of liquid water will eventually cause the molecules to vibrate so quickly they change state into gas.

even under pressure?
I am about to graduate highschool and attend either the United States Coast Guard Academy or University of Central Florida and major in mechanical engineering. Would it be a good idea to purchase textbooks that aid in the subject area or should I just focus on my current schooling? If I do get the textbooks, please recommend ones that aren't insanely expensive.

>Would it be a good idea to purchase textbooks that aid in the subject area or should I just focus on my current schooling?
Focus on your schooling. Make sure you're really solid on the stuff that's going to matter to you as a MechE: calculus & physics.
If you've got that down focus on English and public speaking. Why English? Because if you can't stand up in front of a roomful of coworkers and communicate your ideas clearly or write a clear engineering...
