Does Math ever get enjoyable to do? I know I'm still in lower division math courses with Calc 3/Differential equations, but it's just not fun to do this stuff. I know when I get a job a computer is going to do the majority of he calculations for me anyway and I'll just be analyzing the data, but is there a point where it's not just mind numbingly remembering various theorems?
if we made a simulation of sufficient complexity to allow intelligent life, would that lifeform potentially be able to uncover the fact that they're in a simulation? would they see pixels if they developed the technology to observe their universe at sub-atomic levels? would it be possible to re-write their universe from the inside? is this a stupid question?
I know this is basic but WE'RE CLOSE here's a time travel formula i wrote (using http://www.hostmath.com/) T = time we want to go to time, t = current stationary time, v = velocity and 299792458 metres per second is the speed of light.
This is a pretty interesting topic in my opinion as well.
I am a crossbred guy and I did my research. My father was a blonde man with blue green eyes and my mother was a turkish asian person (she is tanned a little bit but she is the only one of my aunts and uncles) I want to know if I can get children since the asian race is very close to the white one (survival possibilites for an example, hokkaido and kyoto in Japan are two very hot and very cold places so the asian body can adapt there easily. My mother's side of the family is... Comment too long. Click here to view the full text.
>>8146755 That was a mishmash of words that meant pretty much nothing. You care way to much about race when choosing your children, if you actually cared about potential fitness you'd attempt to find an outlier to donate an egg.
>>8146257 According to the researchers, the exhaust being blasted out is actually light, photons that have become paired up with another out-of-phase photon in order to shoot out of the metal cavity and produce thrust.
>the two photons in those pairs are out of phase and have no net electromagnetic field.
>the exhaust photons become invisible from an electromagnetic point of view because they're being masked by their out-of-sync partner.

what's the point of the so-called 'law of everything', the ultimate physical theory? the unifying theory of the universe?
Imho it's just a delusion; from a philosophical viewpoint, wouldn't it be inferred from a set of axioms given for granted? how can that be 'the end'? Physics is an open field per se. How can it become a closed theory i.e. how can every physical truth be derived from the axioms?
>>8146118 two theories that work for different situations.. doesn't that bother you, instead of having on theory that works for ALL situations? that's the point of physics. If you want axioms, go do math.
Explosions are defined by detonation and combustion. Combustion being the process by which energy is transferred through a chemical transmission (conflagration), and detonation is by physical propagation (shock, as in pressure waves).
Fragmentation is probably the best word for a bullet separating in the body. It devolves into multiple pieces. Dissassembles might also hold true, but that's usually a purposeful or otherwise orchestrated deconstruction, not an uncontrolled breakdown.
The problem with all the trolls on 4chan is that I cannot just tell you "trust me" because I might be a troll, but... trust me? There really is a difference. You can find it with either a map of the outcomes or through explicit Bayesian updating.
d = 21.6 (mutational differences found in mtDNA) r = 0.000996 (mutational rate) t = ? so: 21.6 = 2(0.000996) x t or t = 21.6/0.001992 t = 10,843 years. = The amount of years since mankind's earliest common maternal ancestor (Mitochondrial Eve)
God is real, and evolution is false. Eternal checkmate, atheists.
More spookyness from Mars baffles the scientists. They found Tridymite, which is a silica-based mineral that only occurs in super hot temperatures. They occur on earth near volcano sites after eruptions.
How come they barely outperform Japan and yet the Korean studies seem to much more hardcore?
I watched an entire documentary on the guy in Op's pic and then looked up their performance on global tests and they barely surpass Japan and Singapore. I view both Japan and Singapore students to be very lax in their studying.
>>8145120 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.
>>8145027 >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.
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...
