Anything related to using as few resources as possible as efficiently as possible. I'd recommend biology and food production broadly with that goal in mind, because most research in that field assumes massive inputs of given resources are available. Even if they're working on water efficiency, it's still on the scale of millions and billions of gallons. Start working on maximizing water efficiency in a closed loop system of 1000 gallons or something and you should be good.

My local paper's letter to the editor is a bunch of people patting themselves on the back about wind mills and solar energy. I wrote a letter but would like to run it through you guys to see if i sound like an idiot.

>Climate change has been placed in high priority in businesses and politics; however, the talking points are a bit delusional. Cutting carbon emissions by 50% in x amount of years won’t happen without replacing the energy source. Wind and solar are both great but their efficiency is still questionable and they both need subsidies to stay in business, while producing only 4% of our electricity. If we’re not going to have a conversation about our population problem and how the United Nations population forecast on most continents will double within 50 years, then it’s time to talk practical solutions: Fission/Fusion.

>Fission nuclear energy provides 20% of the United States energy. It would be more if oil didn’t drop drastically in the past few years (see our Kewaunee plant). Fission is when you split an atom using uranium. This produces great power but you’re left with a good amount of waste. Steel rods, infected lab equipment, ect, not to mention the average time of the atoms is around a thousand years until they become stable. That is, when ionizing radiation becomes electromagnetic radiation. However, the future is very optimistic with its natural evolution.

>Fusion nuclear is feasible within 20 years (depending on how volatile oil becomes in the future). The hydrogen bomb incorporates the same logic as fusion reactors, which has already been successful. This is the process of smashing hydrogen atoms together, instead of splitting them with uranium/plutonium. This, depending on design, can save up to 99% of nuclear waste, but the benefits don’t stop there. The average time the waste becomes stable is only 50 years, compared to fissions hundreds of years. It produces more power and the smoke coming out of the chimneys are 100% water vapor. Businesses like MIT, Lockheed Martin, Boeing are already creating reactors and engines by incorporating fusion theory. Multiple countries are funding a plant in France (currently the leading country in fission energy) to create a fusion plant that is meltdown proof, China is right behind them.

>What we should be doing is supporting this and get rid of the notion that ionizing radiation is a horrible thing. Just 0.5 ounces of liquid hydrogen can produce as much energy as 28 tons of coal with no waste or pollution. Potassium -40, found in bananas, contains ionized radiation. Also found in kidney beans, sunflower seeds, potatoes, and most nuts. It’s time to think practically instead of regurgitate the most politically popular opinions.

Also general fusion/fission discussion

I liked Bio in highschool and college. Physics was good in highschool too, taking it again in college next semester. Chemistry came easy in highschool too, seemed to be the only one in class who knew what was going on, but i scored not-so-great on my final exam because I started slacking towards the end of the semester. Science was always my favorite subject, but I always ignored chem/bio majors because I didn't think there were any good job prospects besides being a doctor, which I'd like to be, but I'd never go to med school unless I wasnt paying for it, and thats gonna be hard to do coming from a low income family.
TL:DR; What are some good jobs you can get in th chem/bio field? And I guess I'd like to know how hard it would be to get a full ride through medical school?

Don't go to medical school if you aren't 100% sure you want to do it because you will hate your life.

There are jobs in the field, but require MS or PhD. If you aren't into that, look into ChemE.

It's poorly introduced but a simple concept. Any measurement involves photons or some other particle impacting the system and its destination being measured. The impact disturbs the system.

Vaccines are little ufos, could they cause devolution? there was a sharp climb in abortion miscarriage and retarded/deformed babies after 1980, 1980 was when they 12x'd the vaccination rate.

Anyone here like reactor idle or factory idle?

I've found idle games kinda relaxing as the only goal is to optimize. Anyone else on /sci/ play these type of games? Do you have any special techniques or do you just wing it until it gets to 100% efficiency?

pretty neat, going to have to start playing these. How long does it take to reach the max tech level?
>>
>>8144506
The max tech level is probably something that would take weeks to get to but trust me it's hard enough at a base level to figure stuff out. Reactor idle is easier then factory idle but they both got their merits. Reactor idle is more to do with designing heat density maps with heat transfer systems capable of keeping things below critical temp and feeding said heat to generators to make power so money can be made. Factory idle is more about designing input and output systems so as to ensure everything gets the right amount of x resource and the capability to excrete y amount of resource. This also adds in a function where most buildings have an upkeep cost so that comes into play.

How did you study for this exam? I have been working through Stewart like crazy, as well as Dummit & Foote, to a lesser extent.

I need to find a good linear algebra book to study for the exam, too. Any recommendations? Strang? Axler?

Any tips or comments or whatever would be greatly appreciated

I also plan on buying Princeton Review's book, as well as Schaum's Calculus, fully aware of the shortcomings of both. Would really love to get in the 80% percentile, but I'm not so sure this is feasible
>>
>>8144100
Axler's Linear Algebra Done Right is a text that's very theoretical in the style of Algebraic arguments/proofs. I believe that the GRE mainly calls for more manipulation than abstract arguments. In that case Gilbert Strang's books are probably more akin to the GRE.

tl;dr Axler too theoretical for GRE, Strang Good.

Thanks! Are you speaking from experience? I mean, have you taken the GRE?
