Depends on how many light bulbs they sell while pretending they invented it.

Actually... edison did genuinely improve the bulb so this isn't that fair to say to be honest. We wouldn't be using them without his input.
But he certainty never invented the shitty first lightbulb.

I'd rather be an edison than an inventor. I want to make shit that changes the world, not just claim an innovation. That's why proper entrepreneurship is intrinsic to good inventors in the modern age.
Though that said, that can also become a problematic thing. Causing industries that try to kill people directly for money and lie about it.

Well, yeah this is pretty much true. The LHC is testing the Standard model, which is early 1970s physics. There have been new measurements made but this isn't the kind of thing you get famous for.

No such thing. If you can pass calc 1, all math is open to you. It is by its essence logical.

Discovering things in it is another thing, few can do that.
>>
>>16128939
Well, engaging physics at advanced level and not at popsci level is not as easy as writing a gay-ass operating system. So it is obvious that a very few people can actually advance physics and become famous. But your schizo ass should also know that just because you didn't see a particular physicist being mentioned on mainstream media doesn't mean he didn't have an original contribution to physics.

Apparently a couple of days ago some very smart asians (I believe japanese and chinese) wrote a paper on power series composition which runs in [math]O(n\log^2 n)[/math] outperforming (supposedly even in practice) the current ones by a lot.

I wouldn't believe that you can get composition so fast (and in fact I need to go over the paper to be 100% sure).

Do you believe this will be the endgame of new and efficient power series algorithms?

Point is to give a definition of the reals and their arithmetic. Here the approach is to define them as decimals (which is painful as can be seen, hence why sane people define them as equivalent classes of Cauchy sequences or Dedekind cuts).

I don't understand gravity. The popsci explanation is that it's created by the curvature of spacetime and objects aren't actually attracted to one another but are only following that curvature. But that only explains why objects that are already moving fall down. Why would a stationary object follow that curvature and fall? If I drop a pen, where is that force coming from to push it down? Is it because they're moving through time? Please help

I guess I'm not surprised, but you failed to understand my post. The tangent vector of a curve parametrized by the coordinate time is of course not invariant under changes of coordinates.

If you instead parametrize the curve by proper time (or arc length in a Euclidean signature) then the tangent vector is invariant under changes of coordinates. But the norm of the tangent vector is just a constant (1 in appropriate units) and has nothing to do with the kinetic energy.

A shower might be 10lpm. 10 lpm from 4 to 30C is 17kW. The sun might give 1kW/m2. 17m^2 of 20mm OD hose is 850m. You will have to find a way to use less water or find my mistake.

if the hose is always filled with water it would just stay the same over the length of the hose, since you will be heating the same amount of water per hose length.
or maybe i am a retard and didnt understand the question.

"In one recent study that followed nearly 2,000 teenagers as they became young adults, young people who smoked marijuana at least five times were twice as likely to have developed psychosis over the next 10 years as those who didn’t smoke pot."
"One of the best-known studies followed nearly 50,000 young Swedish soldiers for 15 years. Those who had smoked marijuana at least once were more than twice as likely to develop schizophrenia as those who had never smoked pot. The heaviest users (who said they used marijuana more than 50 times) were 6x as likely to develop schizophrenia as the nonsmokers."

Daily weed use was associated with increased odds of psychotic disorder compared with never users, increasing to nearly 5x increased odds for daily use of high-potency types of cannabis.

Smoking anything is a lot worse for you than alcohol. Most alcoholic diseases are a product of long term dehydration, not alcohol itself. I've known plenty of people who drink alcohol in moderation and are completely healthy, but it should be common sense that people who smoke have a lot of health issues, regardless if it's tobacco or marijuana. Your urinary and digestive tract expel foreign substances, your lungs have no ability to expel years of tar buildup, which is why recovering alcoholics usually bounce back while chronic smokers are disfigured for life. Many countries outlaw smoking because it's dangerous and makes people lazy, but only a handful of them have bans on alcohol as well.
>>
>>16131550
Then why do 2M people die of liver failure annually while only about 150,000 die of lung complications and why do people die directly from physical alcohol addiction such that prisons have to give alcoholics alcohol, but smoking tobacco or marijuana doesn't and nobody is obligated to keep them alive by giving them more of their addiction?
>>
>>16131550
Also if the bounceback for alcohol is so much easier, why does alcoholism actively cause blindness, but marijuana seems to protect against it by reducing cataracts and apparently slowing macular degeneration and glaucoma symptoms?
>>
>>16131569
1. People don't drink enough water nowadays.
2. Liver failure is a quick and spontaneous death, COPD is years of torture.
3. Addiction is only part of the problem. You have to consider that it takes years of heavy drinking to develop a fatal dependence to it. Your average person who moderately drinks can go a long time without any alcohol, but I've never known a smoker who couldn't go more than a couple days without tobacco/marijuana.
4. Prison is over 70% African American. Negros and Mongoloids don't handle alcohol the same way Caucasoids do.
>>
>>16131603
1. No, its not a recent trend, and most liver failure is caused by chronic alcohol use.
2. Liver failure is not spontaneous, it can take decades and goes through a number of stages as you spot, get jaundices, and turn yellow. You would still have x amount more deaths per year if one was deadlier than the other. People often dismiss symptoms of lung cancer until its too late specifically because onset is more spontaneous.
3. Lies, with alcohol hangovers are immediate you can be poisoned to death on your first use, hair of the dog is necessary after just a few weeks of daily use, the shakes can set in after only a couple of months, and physical dependence can result in less than a year. Your anecdotes clearly aren't representative since there is an order of magnitude more deaths from alcohol than tobacco/marijuana combined.
4. Are you retarded that has nothing to do with prisons being legally required to serve alcohol to the physically dependent regardless of race, but no such thing exists for tobacco/marijuana because dependency is not deadly.

A charged particle in electric field experiences Lorentz force which determines it's trajectory. What happens to a magnetic dipole in electric field? How is it's trajectory determined?
3 replies omitted. Click here to view.

Wrong. The electric charges have a finite separation. For example imagine a dipole with a third charge very far away from the dipole, along the line joining the dipole's charges. Then the net electrostatic force on the dipole is not zero.

>Wrong
Taking a tone like this just make you look stupid and makes people less likely to want to teach you

Write down the Lorentz force on each individual charge and sum them up. That is what net force means. It is zero.
>>
>>16130524
P

+


In the diagram above, let the positive charge have one unit of charge and the negative charge have minus one unit of charge. Let P be a positive charge of one unit. The distance between P and + is r while the distance between — and P is R (of course making the dipole distance R—r).

Then the net force on the +— dipole is

F = 1/R^2 — 1/r^2

Since R ≠ r, since ethe + and — charges clearly don't occupy the same position in space, the net force is nonzero.

You're an idiot.

>>16130610
That's the electric field dumbass. An electric dipole does of course feel a force in a nonconstant electric field. But we are talking about an electric dipole in a constant magnetic field. Stop embarassing yourself

Electric field is part of the Lorentz force.
