It isn't fire. (It would be on fire if there were oxygen.) We just depict it that way because of its association with heat and light.

The sun also isn't orange. Or yellow. NASA artificially colors their photos of the sun to something people expect to see. The sun should appear green, because that's the light wavelength it outputs most strongly, but is so overwhelmingly bright that it's white. If you actually looked at it in space it would look white.

how much would a ride cost?
according to my calculations based on a 2 stage launch, each person would have to pay $217520 for a ticket.maybe we can shave off $70000 per ticket , making it $147000 since it is only the first stage being used.

how much are you willing to pay for a ride that takes just 9 minutes?

“We do expect that the temperature will rise another 1.5°C in the next 50 years, from continued carbon dioxide releases predominantly from China, India, and the developing world. They need more energy to improve the standard of living of their people, so we need to help them produce energy with low carbon emissions. That means nuclear, energy conservation, and natural gas.”

How to study the transition from Fourier series to transforms?

I get Fourier series but not Fourier integrals

I know transforms give a function of frequency instead of time, but I don't understand the role fourier integrals play.

As a calculus major, I can tell you that the road is hard but worth it. I have been doing differentiation and integration practice 4hrs a day every day for the last 3 quarters at university. It's hard work but I am able to rise above my peers and be the top of the class in CALC 409. Soon I think ill be able to have a basic grasp of the theory involved in computing triple integrals, which is my ultimate goal in getting this degree.

Anyone? Surely there's got to be a flaw in my reasoning. It can't be that everyone is wrong.

>>8953936
Inside the Green movement, it's a pretty common position that industrialization is bad, and the only real solution is to massively deindustrialize, and "get back to nature". It's Gaia worship. Also factoring into their reasoning is the faulty assumption that Malthus was right, and that increasing energy supply means increasing human populations. Also, the wrong assumption that increasing energy supply means humans will be more capable of damaging the environment. It's just wrong on every count. This particular sect doesn't want cheap energy. They want expensive energy. And I suspect that they're the true idealogues that are largely running the movement.

>why should we also reduce our energy consumption if we move to 100% green energy?
>shouldn't we try to consume as much of it as possible to help that industry?

you mention basic economics but i think there's a more basic principle of economics to consider when answering this question. If we consumed 17 TW of power and replaced it with 100% green energy, it would cost $xx.xx per kWh. For every unit of power increase we want to consume, the consumers would have to spend $xx.xx + (some amount). The idea behind market economics is that the producers will find the most economical way to produce things so as to provide them the cheapest. If this were represented by wind farms, you could imagine that all the really great windy areas of the planet are already being used for wind power to generate our 17 TW, but when we decided we want another TW, we have to build those turbines in a non-optimal wind harvesting area. The turbine still costs the same as the turbines in the good spots, but is now generating less electricity - which means the producer has to have a premium per kWh to cover the investment costs and receive a decent ROI.

There is also another economic argument to this; using up scarce resources that have alternative uses.

Lets say even if you get to 100% green energy, a sizeable portion of that power will come from nuclear (this is an inescapable reality). Nuclear power requires thermodynamic heat cycles to generate power (usually rankine cycles). Those rankine cycles are, at best, ~40% efficient (generous). That means that for every TW of power we want to consume, we need 2.5 TW of heat from a nuclear reactor, and 1.5 of those TW of heat needs to be rejected from the process, using a cooling tower. This would use at LEAST another 200,000 gallons of water PER SECOND, or roughly 5.2-5.3 BILLION gallons of fresh water per year.

not to mention the concrete, steel, human labor, rare earth magnets, etc etc that would all be sucked up in this endeavor.

>MMR -> intestinal inflammation
so did they find out whether there's a causal link there?

>>8952953
Talk about jumping to conclusions.

Observations:
Children received vaccines
Children showed symptoms of autism within a month
Children displayed gastrointestinal symptoms and lymphoid nodular hyperplasia

Conclusions:
MMR vaccine caused intestinal inflammation. What evidence is there that the vaccine caused the inflammation as opposed to other environmental causes? Were the vaccinated children compared to non-vaccinated children?

Inflammation caused translocation of nonpermeable peptides into the bloodstream. Is there any evidence given for this, or does he jump straight from inflammation to the peptides? Were these peptides quantified or detected in any way?

The peptides affected development. What evidence is there to support this conclusion?

Really seems like he's jumping from A to Z. And going off his hypothesis, the vaccine didn't cause autism, the intestinal inflammation did, so anything that causes intestinal inflammation would cause autism.

And a quick google search shows that several people have tried to replicate these results and have been unsuccessful. Also that the children in the study were recruited by a lawyer preparing a lawsuit against the manufacturers of the MMR vaccine, and they paid Wakefield 400k for the research, which he didn't disclose. And that Wakefield subjected the children involved to colonoscopies and lumbar punctures not approved by the ethics board of the hospital he was at. Now The Lancet has retracted the paper an Wakefield has lost his medical license.

>>8952953
so 8 children had gastrointestinal symptoms and signs of lymphoid nodular hyperplasia, but the MMR is what caused the autism? There are no controls. How about children without GI symptoms that receive the MMR vaccine? How about children with GI symptoms that never received the MMR vaccine? Should MDs be allowed to do research?

Is this shit really the reason people think vaccines cause autism?

Ye

it's better if you have it prescribed though. Procrastination is not a suitable excuse. If you go to your doctor, he'll send you someplace to have you diagnosed. Once there, you need to fidget the entire time, seem somewhat distracted by your surroundings. He'll ask questions, and make them sound as close to ADHD as possible.
>distracted easily
>can't focus
>devote my attention to something new every five minutes
>fidgeting

Then he'll diagnose you, and you can get adderall anytime you want, so long as you eat regularly, and maintain a constant body weight.

Are they separated? Or is one a subset of the other?

What is a scientist? What is an engineer?

Can an engineer be a scientist? Can a scientist be an engineer?
