Basically if a person is affected by nearby electric equipment or where stuff is plugged in an outlet, are these waves coming from the wall socket and through the extension adapter as well. Can these waves be minimized as in the B example by plugging in a 20m long extension cord in a wall socket from another room. Will the EMF waves only come from that wall socket or will it also be in the cord? by analyzing the picture you know what i want to accomplish / figure out so how would you go about plugging something in while minimizing the radiation?

Why would a human body, an electrochemical machine with it's own magnetic fields, not be affected by large amounts of nearby or strong electromagnetic frequencies or electrical equipment and technology? That just seems like an odd thing to assume.

But that poster isn't assuming anything. He's just conveying a consensus reached by scientists after many experiments and a slow refining of models of the physical world.

Common sense and assumptions are often wrong when it comes to physical minutiae. That's why we have to run experiments and trust data, not human intuition.

Guys,

Chem BS here. I formulate construction products. Pretty damn good at it. But I believe I've reached my salary cap and I'm only 3 years in.

I want to switch fields to make some real money and not just the bread crumbs I currently get in exchange for my research and ideas, but don't know what to branch into. The only things that make sense to me is:

Chemical Engineering
Biomedical Engineering
Pharmacy
Medicine

or just saying fuck all and doing

Finance

What you think?

I like chemistry but fuck the industry that reaps the rewards of great minds while giving back a pittance for reward.

Ayy fam you gotta chill out. You're not making enough money? That's not a problem with chemistry, that's a problem with the company you're working for. You gotta shop around. You're talking all about how you improved their product line, that's some resume shit. Maybe your next step is staying with chemistry, maybe it isn't. But don't take one bad job as indicative of the field.

I'm a chemical engineer working in drug design. I make artificial peptides to target protein interactions. I really enjoy it, and it pays well. Just gotta find something that works for you.

We have kinda been doing this to ourselves in commercial/industrial chemistry. The BSc. In chem has become very "cheap", oversupply of people with really poor skills due to falling academic standards in US university.

I would love to see ACS or the RSC come out with a formal licensure or certification for professional chemists in different specialities.

I manage BSc. chem and bio graduates that can't tell me why phenol is more acidic than methanol or do basic solution prep and analytical calculations.

For those with BSc. specialized experience becomes very important, but you will always be salary caped under 100k. Likely that you wont break 50k untill 5 yrs experience.

MSc. and PhD. people will get better starting salaries and can leverage themselves into higher positions with less professional experience.

Im an MSc. working in a very specialized industrial area and I make twice the salary of a PhD. academic. Get a side hustle consulting in your area of expertise or tutoring for standardized test prep (MCAT, GRE, pharmacy, dental)

Ah thanks but no, those guys are notoriously tight lipped and the complexity of Dwarf Fortress is far beyond the pale of what is necessary or would even be functional for my purposes. Besides, at this point Dwarf Fortress is well studied within the gamedev community and it's easy to get references about how it works without having to bother those two guys.

Definitely though what I am working on has some broad similarities in terms of making a world simulation that leans on emergent properties, but I'm basing it on real world science and chemistry rather than fantasy. Instead of 'mine 5 generic shits and 5 dire poops to craft 1 epic turd' it will be 'collect 75 kg water, 25 kg bacteria, 5 kg protein and 20 kg sugar to make 100 kg of epic turd'

Not so fast!
This isn't completely wrong.
If you could build a box out of PERFECT mirrors
and
If you could keep the mirrored box from losing ANY energy over time...
then following troll's procedure would result in
the input light bouncing around ~forever
However, you could never use the light for anything for anything or observe it, since doing so would consume the meager amount of energy stored by the endlessly reflecting photons.
There is an electromagnetic component to this as well, but I'm pretty sure that a PERFECT mirror keeps reflected radiation from losing energy due to electric or magnetic forces.
Given, perfect mirrors don't exist, and likely never will... however with really fucking good mirrors you could get the light to hang around for longer.
Cooling the entire setup to nutsack shattering levels would help with duration as well.

First off I'm not a complete noob asking if adding hydrogen peroxide to kratom leaf makes 7-hydroxymitragynine.

I'm basically just wondering if it's even possible to extract 90%+ pure mitragynine from kratom. Would such a thing be possible without chromatography? Simple A/B then chloroform and then maybe specific solvents/PH?

The STEM meme has been floating around for so long now that the people who associate themselves with it have a track record of behavioral patterns to analyze. One common behavior of the typical STEMfag is to loudly proclaim that they're more intelligent than those people who study the humanities and the evidence they provide of this is always someone else's achievement, usually the achievement of someone like Issac Newton who was an extensive studier of non-STEM topics and was able to achieve insight by not being a closed minded know-it-all. What is it about the humanities which upsets STEMfags so much? Why are those cringing cowardly sissies so frightened by things that can't be directly quantified? It seems so lame.

I've been enrolled in a Trigonometry course this semester and I have been enjoying it. I also think the main Pythagorean theorem is one of my new favorite equations, but I just don't understand one thing. Why is the result of the expression equal to one?

sin²β + cos²β = 1

We've learned about "proves" where you try to arrive to the answer by choosing the busiest side and in this case the left side, but how would you go about proving this specific this? I heard that more advanced math knowledge was needed (e.g. Calculus) but is that really true or can this be proven using what is learned in Trigonometry itself?

Also, in other Trig courses, do instructors actually assign this expression as a homework question all to itself? I thought this was just a formula given to help solve problems and not an actual problem.

I also recently learned that Pythagoras was a philosopher and even had his own cult. What are some of the other things this man was known for?

The allegory of the cave is a metaphor for epistemology, I don't think Plato was positing it as a realistic scenario, whereas the simulation argument might be taken for a metaphor about epistemology but primarily positions itself as a realistic explanation for reality. (cf. the Evil Genius argument; Descartes didn't really believe he was a brain in a vat, he was trying to prove a point.)
There really isn't a difference between the way our brain simulates the world and a computer simulation of the world; but that itself, comparing the brain to a computer, is just another metaphor, and largely the product of the repeating phenomenon in the history of science where the rest of the universe is re-contextualized as being 'like' whatever the most important technological advance of the day is (this has happened with everything from fire, writing, and wheels to rail-roads and electricity.)

Not to say that he or Pythagoras couldn't eventually understand the concept of a computer and programming languages, and be able to relate them to how the mind and possibly the universe works, but you would need to educate them about all the stuff that underlies those ideas first. Like, the number zero and real algebra would be the first big things.

And yet the work of flatland and explanations of dimensions beyond human comprehension are adequately expressed using the allegory of the cave.

I do enjoy that you make the distinction that belief is not relevant to argument. So rarely do people understand that critical nuance.

the proof was given correctly above but the dude used latin for some reason.

sine is the ratio between opposite side and hypotenuse. sin(x) = O/H
cosine is the ratio between adjacent side and hypotenuse. cos(x) = A/H

pythagorean theorem: (adjacent side)^2 + (opposite side)^2 = (hypotenuse)^2
O^2 + A^2 = H^2
divide both sides by H^2
O^2/H^2 + A^2/H^2 = 1
rearrange
(O/H)^2 + (A/H)^2 = 1
by definition
sin(x)^2 + cos(x)^2 = 1

I am also decent at computers and thought I could do data science things
BUT I believe I can probs pursue data science and art on my own

What kind of time traveling technology are we going to have in the future?

200 years ago the best way to view past events was through art, paintings, drawings, or written text.

In the present we all have smartphones that can record audio/video at any given moment giving us an exact copy of the present for viewing in the future. There is also youtube and other major databases of video/audio from the past that is an exact copy of reality at that given time and setting in the video.

What is coming in the future? Is it 10s of thousands of years from now, hundreds? We're clearly going to have something that is just as much of a mind blowing leap as paintings -> recorded video. Are we finally going to be able to communicate and interact with the past in real time?
