Jesus fucking Christ. There are entry-level sales associates making more money without commissions.

Tell me about it, I did chem eng and its been impossible to get a decent job. Honestly the only """ job""" I've found so far is what is effectively an internship. I'm a graduate with a 3.7 GPA and I've already got experience, is it just the job market right now that's not looking for chemE?
>>7997300
LOL
meanwhile, as a software developer, I will make at least $50k a year out of school.
>>7997300
College is a scam bro.
You can get an entry level job working at the docks for like $20/hr, no experience needed just have to have at least a GED.

Explain the Lorentz transformations to a retard please. I only got the [math](t_{2}-t_{1})^2 - (x_{2}-x_{1})^2 - (y_{2}-y_{1})^2 - (z_{2}-z_{1})^2 = 0[/math] part, and the time dilation via multiplication by the Lorentz factor. I don't get the rest.
>>7997278
Since you don't measure absolute velocities, only velocities relative to your reference frame, you need a way of transforming between the different frame's. Otherwise you'd end up in the bizarre situation where physics was affected by the velocity of your frame. Classically we the Galilean transformation (which if you've never heard of before might help you). When we get to relativistic velocities we find the Galilean transformation no linger works (it predicts that the speed of light should be...

I get that, but what I don't get is the math behind the transformations, and how to get from the classical Galilean transformation to a relativistic one.

/sci/, what is it about math majors and mathematicians that makes them so goddamn smug?
It wasn't the mathematicians who created the metal foam plate that can turn 7.62 mm caliber bullets into dust upon impact faggot.
It was a joint combo of Material Engineering, Chemical Engineering, Metallurgists, and Mechanical Engineers.

How do you define intelligence? Is it a normative trait and any attempt to isolate a definition was ill advised to begin with or does the concept refer to something that has a tangible phenomenological basis that we might be able to measure some day?
If you don't feel like you can define it, who/what would you turn to to define it for you? What is the bleeding edge of intelligence research? Will studying AI get us a solid definition or do we need to study humans? Aliens? Animals in general? How do you create a path that could accurately define intelligence?

Intelligence isnt one thing. Its depth and speed of recall, 30 different kinds of reasoning, creativity, eloquence and a bunch of other shit
>>7996174
This, I would add that there are ontological issues in assuming these are true. However, if we're examining the mind in these frameworks to begin with, which begot the question, think of intelligence like an atom that expands with more nuanced and relevant material to construct its growth; as capacity: if you have one or more of said traits, how well you execute them amounts to its a-typicality. You need to look at the general population and standardize capacity, then you examine your traits and see how well you're...

I would just say "intelligence" is a simplified way to talk about numerous more or less related abilities/characteristics, and that you can be better or worse in each one
Why do people accept the fact that there are natural differences in height which can largely be attributed to genes, but the moment we start talking about intelligence it becomes about hard work, do a majority of people actually believe that intelligence isn't determined to a large degree by genes or is it a vocal minority?
Regardless of whether IQ measures intelligence or not there seems to be a strong correlation between academic success and your IQ, so it's measuring something, For instance my IQ is below 100 and i'm 5'4, people find it normal to discriminate...

Why can't people have an opinion on it if they've read about some of the theories? Like the idea of quantum physics entices me and I love it, but you're saying my opinion is invalid because I don't know the math? Gtfo

Why is the left so against nuclear, when it's clean and reliable?
http://www.npr.org/2016/04/07/473379564/unable-to-compete-on-price-nuclear-power-on-the-decline-in-the-u-s
They mention how costly nuclear is and how its being priced out by "clean" natural gas, as well as solar and wind which are both so heavily subsidized that if those subsidizes were removed their price would more than double.
I am an ultra-leftist and I think we should build a fuckload of nuclear powerplants to provide socialized electricity and fight global warming

From Tractatus:"Frege says that any legitimately constructed proposition must have a sense. I say that any proposition is legitimately constructed". Laws of syntax are similar in form to ethical laws: thou shalt not (form such and such sentences). Wittgnstein's response in both cases is "and what if I do?" Frege attempted to justify syntactic rules ("laws of logic") by appealing to other laws of logic, so did Russell with his type theory to avoid contradictions of self-reference. Wittgnstein rejects this idea as "clearly" wrong.

Thank you for your submission. Other users have reported the same bug, and our developers are working to resolve the issue in time for the next patch. We apologize for any inconvenience. Thank you for using math.

I have learned two things about osmosis across semipermeable membranes:
#1: Osmotic pressure is defined as a solution's ability to resist an inward flux of water (i.e., a solution's resistance to osmosis).
From wikipedia:
>Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
Osmotic pressure is given by [math]\Pi = iMRT[/math]. Higher osmotic pressure means lower inward fluxes of water.
#2:...

Both happen at the same time and eventually reach an equilibrium.
Oh hey you're that anon that tested his π latex in that one thread from earlier.
>>8008818
To further expound on this: If you consider the osmotic pressures of the two solutions in the pipe on the left in my OP picture, you can see that solution P1a has more solutes than solution P2a, and thus P1a has a higher osmotic pressure than P2a, which dictates that water will flow from P1a to P2a.
This clearly does not happen, as evident by the tube on the right-hand side, where the opposite has happened.

How dangerous is the pill? Someone said to me they are extremely dangerous and if you take them for many years you really mess up your body. Is that true? Are there any serious sources as I'm not trusting those "medicine websites" telling me the only side effects are rare and probably just headache, etc.
>Are there any sources that will solidify my confirmation bias
>>8008435
So... who exactly ARE you willing to trust?
>>8008435
Not usually anything serious, pretty similar to any medication really. It actually protects you from certain kinds of cancer, so thats nice
