How fucked are we? Are there any viable solutions? How will the world look like in 50 years? 100years?
Forgive me if this isn't the right board but i'm too hot to do a lot of effort.

Does a machine that uses 500W emit more em radiation shit than a device that only uses 250W? also where is the source of the radiation, is it through the power outlet where its plugged in, and if it is, the further away from the power outlet one is the less exposure to radiation one will experience?

>>79534 I do partially agree with >>79535... but we also know that school sucks at conveying information. Internet kooks don't exactly help in this matter either.

Now, EM radiation is basically anything from longwave radio, microwaves, through visible light to gamma radiation....
But still it's hard to say whether a 500W device will generate more EM radiation than a 250W device. Wattage itself is a measure of how much *energy* is released. Energy in itself can be released in other forms than EM radiation, like kinetic energy.

In some cases it's true, A stronger lightbulb, radio transmitter or microwave oven will release more EM radiation than a weaker one - on the other hand, the very purpose of those are to generate EM radiation (microvave radiation, radio signals and visible light respectively).

Compare, however, two very different devices, and you'll see it's not entirely true.
A car engine, for example will likely emit less EM radiation than a microwave, as its primary function is to generate kinetic energy. Car engine power can be measured in the range of kilowatts (thousands of watts) compared to the microwave oven, which is usually 1 kW at most.

Now, even a relatively weak car engine outputs around 100kW - a hundred times more than the microwave oven, probably 80% of that goes to moving the car, while 20% is released as heat (which can be released either as EM radiation or be conducted though various materials eg. air, water or metal). Comparatively less energy goes to generating EM radiation in the car engine than in the microwave oven, as again ,the purpose of the latter is to actually generate EM radiation of a certain frequency in order to excite the water molecules in the food.

>em radiation shit
Don't fall into that ballpark... our universe is dominated by EM radiation - you'll never be free from it :)

They explicitly state it's granite though usually cold cut uses iron filings.

It's not super fancy really just clever use of fairly well established technology. The really clever bit is that if you have a compartment which is hot but out of oxygen you can punch in and use the mist to cool the compartment down (because all the water evapourates, and because it comes out as a fine mist it does so quickly) and so when you open it up, reintroduction of oxygen doesn't cause the fire to restart (as you've now removed another part of the "triangle")

I feel that is appropriate to the topic. nb though because I knew all this.

https://en.wikipedia.org/wiki/Protein_primary_structure
>Protein primary structure is the linear sequence of amino acids in a peptide or protein. By convention, the primary structure of a protein is reported starting from the amino-terminal end to the carboxyl-terminal end. Protein biosynthesis is most commonly performed by ribosomes in cells. Peptides can also be synthesized in the laboratory. Protein primary structures can be directly sequenced, or inferred from DNA sequences.

I started a thread on /spooky/ asking for any evidence of the paranormal or supernatural.

Instead all I got was a bunch of personal attack and people babbling nonsense and presenting it as truth. Then when shown they are incorrect with verifiable data rather than pseudoscience they resort to personal attacks again. They and pretty much all other magical thinkers take any sort of challenge to their beliefs as a personal attack.

I was at a party a few months back and some girl was talking about how she went to some yoga guy who does "laying on of hands". Which involves doing yoga while a dude puts his hands on your body and makes weird noises. Supposedly doing this achieves any number of effects from healing wounds, curing depression and other supposed boons.
not arguing the therapeutic effects of yoga just the laying on of hands part
I tried to understand what she was explaining to me by asking questions. Like asking her what was actually happening because it made 0 sense to me. Instead she started insulting me for being closed minded and shit.

Also in real life I live in the US south. Where people who think the world is 6000 years old is the norm.

Needless to say I deal with people who use magical thinking on a regular basis.
They are 100% willing to reap the benefits of science and the technology that comes with it until it conflicts with some myth or story about ghosts or some shit some one told them. Then all reason and logic go out the window.

Why do so many people especially in the us reject verifiable facts over what feels good? I went to the same public schools as them, I was also raised in a religious household (jewish, although I'm no longer religious). The only difference is that I chose the rational answer.

Idk, maybe I'm just a giant nerd who paid too much attention in school. It's frustrating living among all these science denialists.

Also all of the above isn't a rant about religion. You can be religious and a realist, I have several christian friends who understand their religion and all others aren't meant to be taken literally. I actually respect people who can strike the balance between their religion and what the real world shows them.

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.

I think the video is supposed to be pretty self explanatory.
From what I've seen he is starting with a ray from the origin (0,0) and 0° degrees. Then measure the distance to the first edge of the madelbrot set that the ray intersects. The magnitude of the resulting vector is then used as the first sample of the audio.
Then increase the angle of the ray, and repeat the process.

This is an interesting idea. you could even modify the sound if you pick different origins for the rays instead of 0,0 (should work as long as it is within the set)
or alternately use the same process with different Julia sets.

All in all neat idea!
I would find it quite interesting if this could be turned into an algorithm suitable for real time sound synthesis in a VSTI and such.

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)
