Does /sci/ prefer whiteboards or blackboards?
I haven't met anyone who prefers whiteboards over here so it's a fucking mystery why they're so popular.
Is this just my country sucking or do whiteboards also plague where you live?
Blackboards for lectures, but whiteboards are better for closed rooms because they make less of a mess.

>not writing on glass masterrace
writing on boards are for brainlets who couldn't evolve beyond the beauty of writing on elegant glass
I started uni this year and I love whiteboards so much after 12 years of blackboards. everything is much, much cleaner and they're almost a joy to write on. why do people prefer blackboards?

If you want to solve it you get an disguising improper integral of
[math] \int_{15}^{\infty} \frac {5Si(x)}{2} [/math]
Which literally can't be evaluated.

>yfw you inherited the smart genes from your mom but your dad is a brainlet and he refuses to believe you when you tell him you only need to study for a day or two before the exam to get good grades and he insists you have to spend two hours a day every day reviewing your notes and lecture slides
why is my dad such a brainlet? they should all be gassed desu...

>implying he is a brainlet
He has better memory skills than you OP
>>8495516
I never studied for an exam before college. In college I would study the day before the exam.
You're a brainlet for even considering needing two days to study and your dad is a brainlet's brainlet.
You should be able to solve this,
Left to right, top to bottom:

4 equations, 4 unknowns. Assuming there is a solution to this system of equations then yes it is a simple exercise in basic math to solve.
Do you think it is lamentable that scientific studies about racial differences are effectively banned?

Ohh a movie based on true events. I'm sure it shows me the event in an historic accurate manner and doesn't completely warp it to make it more exiting.

That categories are a lot more useful than just as organizational formalism.

Yes
It's one of those things that you believe unquestionably if you don't do any reading about it all, begin to heavily doubt after doing some light to mid reading, and then go back to unquestionably believing after you do heavy reading.
Smart people, I have heard, lurk here. Seems reasonable to assume some of them must partake.
Whenever I do, no mater what strain, always traumatic paranoid delusions, even in extremely small quantities.
Anyone similar experience has found the right type, assuming one exists.
I have heard can be very good anti stress. My work is high stress, would like to unplug and relax with a natural assist.
Thank-you smart awesome people.

Consider three circles of radius 1 placed at the corners of an equilateral triangle with side length 6 and shoot a ray from the centroid of the triangle. Given the ray reflects in usual way how can I determine an initial direction that traps the ray?
After this I would hope to generalize it to a ray shot from a general position and more general convex bodies.
I don't know.
>>8491081
There exists multiple trapped rays.
Have it approach the line of shortest distance in the limit.

I don't think it would be possible to actuall define a function which takes the degree of the laser and says you where the beam would end up. This construct would have a very chaotic behaviour so I guess you illustrate the soultions you would end up with some kind of fractal. The only possible way I see is to calculate the path for every single degree with simple geometry.
Why are most people attracted to the opposite sex instead of same or both sexes?
Pic not related.
>>8495101
Because thats just how god made us
>>8495101
Because the one's who aren't attracted to opposite sex won't produce offspring with those shitty genes. Also, most people are attracted to both sexes to some extent. They just won't admit it.

What is this satan's spawn of a book? Am I just too stupid for physics or is this book just really hard for a second year?
>>8498605
It's you, not the book.

just do the excercises and you will start getting the hang of it

I've had this idea for a while now. Let t be time you've lived so far, and Happiness(t) be a function of how happy you are at any given moment t. Then how good you've lived your life will be measured as an integral of the happiness function. If this evaluated over your lifetime is greater than 0, then your life was worth it, less than 0, not so much. Thoughts on my philosophy?
>>8498519
>anon unironically mentions happiness
>mfw
>>8498522 cont'd
this thread needs more schopenhauer memes
good gracious, I have plenty
okay, well, first of all you don't define happiness, so this thread might as well go to trash, but for some unknown reason I would like to have you explain yourself
so... go on
>>8498519
But you've just shifted the problem, now instead of agonising over how to decide if you've lived a good life, you'll agonise over how to define the happiness function.
