/sci/ - Science and Mathematics

I ran a program and found out

n=60i-35 a=5 b=15

n=24i-11 a=2 b=3

n=84i-35 a=7 b=7

n=84i-11 a=1 b=7 (i is natural number)

these and the cases anon stated would satisfy all,I assume.

I think there should be the smarter way to solve this problem as OP said.

It is ridiculus that you must break it into 84 cases in order to solve the problem.

Sorry for bad English.

So, for a start: a lot of these disorders cause behaviour detrimental to society as a whole and I hypothesize that a lot of societies implement prisons, correctional services and things in response to these kinds of misbehaviour.

So, some parts of society that may have been influenced by the need to respond to individual misbehaviour due to mental illness could be:

- Shame

- Chivalry

- Honor

- Morals

- Don't hurt women or children

- Religion

- Religious morals

- Spiritual advisors such as Rabbis, Priests, etc…

- A feeling of belonging to a group or family

- Government

- Prisons/Jails

- Correctional services

How can we test how societies differ in response to mental illness though? Are there any empirical examples of societies or social groups that have had more or less instances of mental illness in their population?

I know that atheists may have higher rates of depression and other problems and certain Jewish ethnicities have higher rates of some mental illnesses. Have many athiest or Jewish social groups developed any unique features in response to the pressures on their social groups because of higher rates of certain mental illnesses? What are features unique to atheist social groups and Jewish social groups?

>I was recently invited to give a talk at a University. During one of the off-moments when my hosts and I were sitting around chatting, the main host mentioned that he doesn’t believe sexism exists at his institution. As proof, he pointed out that he had just hired a female post-doc. When I asked how many other female post-docs his dept has, he said – well, she’s the only one. The female in question was there, so I asked her to tell us her story. Her story had interesting examples of bias all along the way, which made us think that this particular woman was pretty tough to have stuck it out. It’s possible that Mr. Host might have started to understand that it’s not a level playing ground.

Maybe there weren't many female applicants.

>>2408

Is oblivious that despite STEM preferential hiring practices women are discriminated against because a guy wore a shirt.

They should take women's studies as a major to learn more about how they're aren't enough women in stem

Reminds me of that sci fi book series in the 90s that had to do with teens morphing into animals fighting these jewish alien slugs. One of the books details how the good "god" of that sci-fi universe evolved from an alien to a technological deity of spaceships who fought against evil and then eventually was absorbed into a black hole and merged with the fabric of spacetime to become a true deity/god.

First off, don't listen to these kinds of people (>>2352).

I work for a downstream refining company. I specialize in separating polymer precursors from the nasty-ass bottoms off the main distillation columns. I'm 24, and I make over $120k a year. Look anywhere you want and you will find the same thing: Petros are paid more than any other subset of engineering. See: http://www.bls.gov/ooh/architecture-and-engineering/ for good data on all engineering occupations.

Outlook: it is highly dependent on the price of oil. When oil dropped sub-$50, people were being laid off left and right on the extraction side, while there were only minor layoffs on the refining side. You will still be making a lot of money either way. Interestingly, midstream is the most boom and bust of the three sectors of the oil and gas industry. The key is to be either A) really damn good at your shit or B) get into management.

Respect: Depends on who you talk to. An environmentalist will always bear hatred for you, while your bank account will love you. My mom works for a biofuels company and she has some resentment, but is glad that I can support myself. If you work on the downstream side many of the processes there (separations, heat transfer, fluids) translate into other Chemical Engineering related fields, like chemical manufacturing, food processing, and biofuels.

Now for my next point: a petroleum engineering degree is not the best degree to get. Early in your career it can be a slight hindrance unless you specifically want to do oil. After about 5 years, it's more about prior experience than your degree. It also pigeonholes some of the concepts that work in other fields to oil and natural gas. It's worth having exposure in reactor kinetics and biological processes in addition to the transport side that a PetroE degree would heavily emphasize. Remember that chemical engineering is both a very broad and very specific field that is composed of these subfields (including ChemE itself):

-Petroleum Engineering

-Chemical and Biological Engineering

>>2355

what about mechanical? can a mechanical engineer work in petroleum industry?

>>2355

I really don't like you dude.

>>2355

Thanks man, I been thinking about it civil will be in high demand and is in high demand in my state and will be when congress starts pumping money to fix bridges and roads/ all the infrastructure in the US. After I saved money and I feel like leaving the field I would probably get into chemical because of all the possibilities.

Thanks again.

>>2379

>>2360

Yes, many do. However, they are generally constrained to areas dealing with flow as they do not have the chemical background required to to separations (unless they have experience in that area). You'll find most MechEs in midstream and flow transport at refineries and extractions sites, but the real money and viability is where the ChemEs are (separations and heat transfer). Many MechEs make good money, but if you still can switch majors, choose ChemE if you're supremely interested in the petroleum industry. If you're a MechE and in college, your department should have a mentor program (mine did) that would allow you to network with a MechE in the industry.

>>2379

Whatever.

>>2385

No. Don't go back to school to get another B.S. or B.E. This is a waste of time and money. Chemical Engineering is a pretty closed-gated community, especially to people from other professions. MechEs can get in if they've dealt with fluids fairly exclusively or did materials. CivEs, like Aeros, are NOT transferable to this profession (at least not easily). Civil is always perceived to be in high demand because of what you say. "Oh, we need roads/bridges/buildings. I'll always be in demand!" Wrong. You'll be working for one of two groups: a contractor or the government. Gov CivEs have decent job security but aren't paid well versus contractor CivEs, and vice versa (early in career). Once you're established in a company, you can have your cake and eat it too. Plus, Congress is not going to feed money into our infrastructure. It's just not.

Get into chemical now. Why? You're still in school. It's the hardest major there is given the breadth and depth of what you have to learn in four years. You have to understand System Balances, Calculus, Differential Equations, Physics (minus relativity), Statics, Dynamics, Fluid Mechanics, Quantum Mechanics, ALL of Thermodynamics including chemical thermodynamics (not taught in any other major), Statistical Mechanics, Statistical theory, Heat Transfer, ChemicPost too long.

From those lines alone the only reasonable solution is to kill your dumb self.

I realize I am a fuckton of days late, but you'd help us a lot if you gave us a minute by minute recollection of what happened, OP.

Telling us in which situation the cut was made, with what, and the like, would be good.

I really hope you didn't get it infected, anon.

Also, a fun activity is inventing symbols for higher radixes of choice. That can help to personalize the lessons.

If you're asked why we use a base 10 system rather than something else, that's obviously because most people learn to count on their fingers.

Conservation of energy was broken in the 1930s. Inside nuclear reactors, matter is (literally) converted into energy. Look up:

https://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalence

>>2234

Energy is conserved in the EMdrive, the quantity that is not conserved here is momentum.

>>2323

Energy is conserved in a nuclear reaction, precisely because matter and energy are equivalent.

No, it was measured to be arriving in the detector before it should have been, which means either

Or

The light went a shorter distance than it should have.

So a giant Dragon could work but it'd need a more extreme power source than just food. That's where fission comes in, fission had a low power to weight ratio.

>>2335

the problem with that idea is that you would need a neutron shield, and i don't think anything evolutionary could allow that to be developed. it would lead to too many disadvantages for survival to reproduce, like lead poisoning/cancer and other various shit a dense enough shield would cause.

>>2340

Thorium would be a more probable bet.

>>2326

The plot is primarily focused on the after-math, actually - I kind of want the disease to be deadly in its second iteration, because the plot itself mostly centers around the question/task of "rebuilding humanity" with a small group of characters that survived because they had been affected initially. I was thinking it would be cool if the initial exposure (to the non-deadly strain) happens in a small location with only a few people (not sure what this location would be - hospital, maybe) but then these people leave and go back into the world, some years pass perhaps, and then when it hits again and everyone starts dying, and they are immune, they think they are the last ones alive but they eventually start finding others that just happened to be in that location at the first instance too, and soon they work out where their immunity came from, and they know there are at least 100 (or however many it was at first) people out there still who are also immune, but the task is to find them, as they are now spread out all over the world again.

Not sure how it would spread, what do you think would be best?

>>2327

Maybe rev up the numbers a bit - 100 is pretty low concerning genetic variation. Would lead to inbreeding n shit. Maybe 5000-10000 or even more - genetic degredation can happen very fast. Maybe have the initial form infect an airport for good dispersal.

Air or water should be the way to go. They are unavoidable, fast and intrusive. Excretions from the body are very slow, see HIV compared to the flu.

>>2329

Airport is actually a brilliant idea, thanks! - gives me the opportunity to have a real variety of survivors. I guess they would quarantine it at first, then when they find that people are surviving they are allowed to return, but THEN the mutation happens once they are all back out.

Okay, do you think air would be faster than water? That intuitively makes sense to me. Would a timescale of a year be realistic for an airborne virus to wipe out pretty much the whole planet?

>>2330

Dunno, but since everyone would be dying left and right anarchy should follow soon after and accelerate it furthermore. I think about 1-2 years.

Air would be better, but people could use facial masks. It just needs to spread VERY rapidly and VERY aggressively.

Vaccines are basically weakened bacteria so clearly it does work.

However, when the pathogen acquires virulence mutations, it might also gain mutations that change its immune profile, so that immunity against the less virulent ancestor no longer applies. Especially with viruses, I suspect it will be all about the coat proteins. But once you start fucking with the coat, antibodies that bound one won't recognize the other.

As for the treatment, sure. Consider staph aureus. If you give it a few genes for antibiotic resistance, you get MRSA which is much harder to treat with antibiotics (which are otherwise very effective at controlling bacterial infections). But the effectiveness of your immune system won't be impacted much.

Not to say your thread is inappropriate here, but you might have better luck on /tech/ or stackexchange.

>>2343

It probably is, yeah. Thanks.

>>2338

Metals dissolve into one another very easily. If everything is molten, there's basically no energy barrier to prevent atoms from moving through the mixture freely. Because it's hot, the atoms move fast, so because of thermodynamics they form an equal mixture.

Below 1000 kg, you can basically just throw in the ingots, keep it above the highest possible melting point for 10 seconds and have a homogeneous distribution.

If you're below the highest melting point, you need to wait for the solid lumps to dissolve in the liquid. If you try to make bronze but are below the melting point of copper, using copper shavings would indeed make waiting shorter.

I would personally brace for impact by grabbing the chair/doors and tighten my legs so I have less chances of flying through the window.
