Hey, sci, I need a lil help. I want to study software engineering and code. That requires mathematical understanding. However, I am total trash at math. I understand logic and everything, but all the numbers and symbols are a bit daunting to me. How do I enjoy maths?
What do you mean "logic and everything"? Have you taken a course in discrete mathematics yet?

Read Lang's Basic Mathematics
MATLAB for Ubuntu. Don't judge, just link your best torrent.

Maybe try Octave if you're using ubuntu.
i have a legitimate question
statistically how many people in the entire world do you think would legitimately kill another man to have pic related breakfast?
if no one can answer someone send me to a board that can, ive been thinking about this shit all day
Why a man? That's misandrist.
>>8173135
A very small number, mostly poor, considering how boring said breakfast appears to be. I'm not saying it's bad, but it's not hard to make or find cheap.
How do you guys motivate yourselves to study for stupid/boring classes?
I'm a Math major and my concentration requires me take this 1000 level Elementary Stats class (non Calculus based), but its so fucking boring I have a hard time studying for it.
It's definitely not difficult at all. I just have a hard time studying for this type of shit.
I'm going into Applied Math and I want an internship but I don't want to fuck my GPA with a C.
I know it's a mindset, but any tips are appreciated.
suck it up
suck it up
although, non calculus based? what the FUCK is that? even calculus based is babby shit, measure theory based is where it's at
>>8173120
Histograms, Standard Deviation, Z-Values, Probability, etc.
It's pretty fucking boring to be honest.
I was curious as to what study methods you all use for classes you don't care about and what you all use for your source of motivation?
How small can you make a nuclear reactor?
Could you make one that would fit into a standard train locomotive?
>>8173005
Forty millimeters.
Yes.
>>8173008
That sounds like it might be a nuclear battery, not a reactor...
>>8173012
Since you seem to have a size in mind and 40mm is as small as we can get. Go up from that until you hit your smallest size possible that you still consider a reactor.
Well here's something to think about.
Its no secret the majority of users on /sci/ believe they are exceptionally smart, much more so than the average person. To be clear, I am not questioning this statement, I am using this supposedly correct assumption for the following statements.
With people here being greatly intellectual, and able to pick up new subjects with ease on their own, why would anyone limit themselves to working for someone?
Surely with this this drive for learning and accrued knowledge, a person can choose to create something great...

Because I can do what I want without dealing with all the bullshit of running my own business.
working under someone is less responsibility, less risk
>>8172956
This, but I'd like to add that owning a business takes too much time and can limit the learning capacity of a person.
Would it be incorrect to say that spacetime behaves relationally but exists absolutely?
We can perform a Lorenz transformation which means it is rational.
We can spin relative to space itself without any other need for a reference frame which means it exists absolutely.
>>8172984
>We can spin relative to space itself without any other need for a reference frame which means it exists absolutely.
I've come to understand that this is still out there.

General relativity gives strong evidence that space must exist absolutely. Gravitational waves demonstrate that space can behave like a medium. There's also the idea of curving space. If space can curve then it must exist absolutely in order to have shape.
Is Liz Parrish based? Will she be the saviour of the human race?

>>8172885
She is worse than hot wheels and science nigger combined.
>>8173077
Explain
>>8173077
Why?
/sci/ if one were breathing straight nitrogen how many breaths would it take to pass out?
how much nitrogen would be lethal? Would the body regain consciousness?
its the exact same as dying from oxygen deprivation, so a couple minutes to pass out and then you'd die unconscious.
nitrogen doesn't harm you like its toxic, stupid question desu familia
desu
why does " t b h " get changed to desu wtf
Do we need more people?
What are the arguments against enforcing birth control in countries with high population grow?
>>8172184
>What are the arguments against enforcing birth control in countries with high population grow?
muh racism
>>8172184
Short answer is freedom. Telling someone they can't procreate is taking away a basic human right.
> in countries with high population grow
In countries with high populations or growth. In a country sparsely populated, a 3-4 child per couple per generation growth rate is probably sustainable.
>>8172184
no, it should be enforced in countries with low population growth.
1 person from the united states consumes 32 times more resources than an ethiopian person. If anything, "overpopulation" comes from first world countries, not third world countries.
If you think we need less people on earth, start by an heroing, because you're the problem, not some random nigger in india or africa.
why is it that we always cycle against headwind,
just selective perception or something else ?
>>8172137
Yes, or you just mistook wind from air friction.
>>8172137
wind direction is influenced by spinning wheels.
>>8172137
Basically you have to know that there is no wind per se. What you feel is probably friction as >>8172151
says. Wind is the thermodynamic process of two systems with different temperatures trying to get into equilibrium. When you move at high speeds, what you feel is not wind. Therefore, you will always get "something" blowing in your face.
Engineering undergrad here. I'm just wondering if anybody here knows if I can work in conservation or environmental projects as a civil engineer. I'm asking because I've been reading a lot about my homestate's wildlife, mostly about the Florida panther, manatees, and Burmese pythons, and how the Everglades are dying and it makes me want to do something to try to solve these problems. I don't want to become a field biologist because I think that's very limiting but I do want to be able to work on something related to the environment. Is this possible...

>herp derp solve my problem even though I am supposed to be smart enough to solve it myself
>>8172116
At my school we got an Environmental Engineering program. Essentially they work on quantifying the resources in an area, how to effectively harvest them and how to prevent said harvesting from having a negative effect on the capability of the ecosystem to sustain itself. They also do a lot of work on trying to make sustainable energy and water sources.
>>8172121
Yep, same here, we have specializing programs for nearly every field of engineering.
What's the expectation abd variable of the stochstic process giveb by
[math] dX_t = (X_t \, (1-X_t))^r \, dW_t [/math]
?
I'm mostly interested in r equals 1/2 or 1.
I could add that it came up in modeling a distribution that can't take values outside of [0,1]. For r=1/2 it's a variation of the stochastic term in the "CIR model" and respecta the bounds I want

Brainlet here, how do I solve this? It kinda looks like Euler's identity
>>8171839
>implying there is something to solve
>>8171839
It's divergent
>>8171848
We talked about euler's identuty in class and our professor gave us that infinite expression to solve.
It's just salt you guys. It also points to there being hydrothermal activity.
