I like salt. I am told salt is bad for me. I am never told why, but just that it is. Given that I assume salt is bad for me because the government said so, can that not be offset by drinking lots of water? Water absorbs salt.
>>7913091
salt makes you too lazy to fucking google "why is salt bad for me".
>>7913097
I don't want to hear it from google, I want to hear it from /sci/. I can goolge "why salt is good for you" and get a million reasons why it is. Doesn't mean its true.
Salt undoubtedly causes damage to your body, but the damage is pretty much negligible unless you ingest a lot at once. We're talking mouthfuls. Any damage caused is completely restored in no time at all. Dehydration can be an issue if you don't keep adequately hydrated regardless of salt ingestion. Otherwise, you're fine.
Evolution says we evolved from monkeys. But what if actually monkeys evolved from us?
You bring up a good point
Look at America, for example.

Is asteroid mining just a meme, or will it become a reality?
Planetary Resources claim they'll be able to do it in 10 years. They seem to be doing SOMETHING anyway (http://www.planetaryresources.com/company/#timeline), though getting people to invest in a company that won't do anything serious for a decade is quite an achievement.
>>7912738
companies do this shit all the time. they are called pump n' dumps, or boondoggles. basically you get to pay yourself a salary blowing through other peoples money while you basically do nothing, and its totally legal.
good work if you can get it as an engineer.
>>7912738
>will it become a reality?
Eventually.
Once you have a serious off-world economy going you'll see strange things happening though, the possibility of enforcing a space based economy will be challenging for earth governments.
I had a chat with one of my lecturers at uni about this once, he said asteroid mining is more than likely going to become a reality in our lifetimes since we're going to run out of certain materials/elements soon (like say, helium) and at that point it'll be a profitable investment. Although for the next 10-20 years at least, I don't really see it happening.
Are penguins really birds?
I mean by definition a bird is an animal which can fly.
They are descendants of birds. Really "bird" is just the class aves of vertebrates. It doesn't imply that they fly.
They fly in the water.
>obvious bait
make sure not to fall for it guise
anyone have experience with tutoring maths and physics at pre uni level?
no one been a tutee or tutor at gcse or a-level? really?
>>7912538
I have I guess, why?
>>7912538
Yah, shit was mandated at my highschool, if that's the level you mean.
If space is expanding faster than the speed of light, does that mean an object can escape a black hole's event horizon eventually?
>>7912460
>If space is expanding faster than the speed of light
It isn't, it's expanding at 70km/s/mpc

How do we deal with people who refuse to accept overwhelming scientific evidence? Denying facts like the existence of man made climate change, gender fluidity, and biological differences between races is inherently problematic.
You aren't allowed to pick and choose scientific truths.

don't reply.
>>7912437
Not an argument.
>>7912427
>climate change
obviously real.
>gender fluidity
can't be proven or disproven
>biological differences between races.
huh?
Hi!
I'm not normally a frequent visitor of this board but I came across an IQ test which I solved, but happened to ran out of raw genetic intelligence in four cases. Having found no answers for any of these particular patterns online, I thought to myself this could probably be the place to ask around.
So, please, if you have a decent CPU in your head, give it a try. The patterns in question are in the uploaded picture, if you want to give the whole test a try, well, here's the link:

Comment too long. Click here to view the full text.
In order of answer:
A B C
D E F
35. F
27. D
32. D
34. Still couldn't figure out. Best choice currently is C I guess.
>>7912431
Edit: Just tried the test, got 143, the answer for 34 is not C.
>>7912431
Thank you so very much for your answer! :D
Could you pretty please elaborate the reasoning behind your answers?
Has anyone you've known actually vomited from anxiety?

Is it true that Americans don't have Calculus in High School?
Worse is that there's no proofs
They miss the essence of math in favor of mindless computation
Only shitty inner city school don't. All others have Calculus, and some go all the way to Multivariable.
>>7912147
American here.
Had logic and induction proofs in precalc.
However did not have any proofs in Calc.

I don't understand all the hate the education system gets at least here in canada as a teacher I hear a complaints like this ALL the fucking time
Do these people not understand that there are classes like world issues, fiance and accounting are just examples of ways to learn all classes that you can learn in free time anywhere or online
what do you guys think why this happens?
>>7912101
oh also pic unrelated
The fuck is this shit
>>7912112
if you are asking about the picture it is a simple representations of genetic modifications I am working on for my grade 12 students
So, uh
How game breaking would it be if some student found a way to calculate infinitely large prime numbers?
not possible
first take this example
all even integers can be represented as 2k, meaning that 2 is the only even prime
if you multiply infinity by two, you get infinity, meaning that infinity is not prime
of course you can also argue that infinity is odd
infinitely large primes is a nonsense concept anyway
Do you mean arbitrarily large?
It would be pretty big but the problem is out of reach of pretty much every non PhD student.
quantum computers (if they ever get made) can do that with their parallel processing
Hey /sci/,
So as part of a lab I pictured a piece of unidirectional CFRP in a scanning electron microscope. Only thing is I got a strange pattern of tensile and compressive failure (picture included).
What global loading could lead to this failure pattern? Any help is greatly appreciated.

>asking questions about the actual practice of science

I think you've misunderstood where you are. Please restate your question in the form of a shitpost.
>>7912262
I'm just asking in an attempt to understand what's going on. I couldn't find anything similar anywhere online so was just hoping that somebody on here had seen something similar.

This isn't my first tango, friend.
What strange things have teachers told you?
>"The only difference between mathematicians and coms sci majors is that comp sci major don't know calculus, are you a comp sci major ?" A former teacher at my faculty when asked by a student why we had to do "hard" calculus problems.
(Since my faculty has both a computer science department and a math department ,they used to be joined a while ago, like 10 years ago, and even both majors had the same courses for almost 2 years)
