Or at the very least should there be an option for weaker students to take a slower path to reach a qualification. As long as they are able to prove they have the knowledge required for the qualification is the time it took them of any value?

Many people fail courses but when going back and redoing them they achieve the grade, they have effectively had more time than anyone else but does it really matter as long as in the end they understand the information?

The responsibility of educational systems is not to lower its standards for weak students. There are good alternative paths for people who are not good at school, such as learning a trade.

The current educational system should not lower its standards to help weak students, that would cause a decrease in skilled workers being created. I agree with that

I don't agree that weaker students should be forced to take different paths in their life because they lack in the speed necessary to learn information in a short enough amount of time.
There are more aspects to being a smart person than how fast you can pick up a subject and I believe it is bad that the education system focusses it to be such a dependent factor in who passes and who fails.

Try reading biographies of famous mathematicians.

Following the use of it here, he really means "how". Of course we can't answer that much better at the moment but it's more meaningful to ask at least.

Literally the only two requirements of what I proposed are being able to create a uniform and stable but very hot temperature, and vibrating whatever is being heated.

The rest is just patience.

Would it work?
Who knows!

What? Read the books. If you go to college and aren't doing your own reading on top of your coursework then you aren't going to last in your field anyway.

I hope you realize thats more or less just an encyclopedia and nothing special on its own. You can literally read all of that shit online and not have to deal with all of the significantly outdated portions of the book.

this. people who are interested in what they are studying will succeed. those who arnt will inevitably fail at some point in their careers.

Stochastic Calculus & C++

Just major in what you like. It's a good idea to know a lot of Stat though so pick up statistics somewhere.

I don't know much about finance books etc. but you can pick it up as you go.

Mathematical Finance? The only thing that comes to my mind is Option Pricing (Financial Engineering).
This requieres a lot of understanding of different pricing models. A good start would be to properly understand the Black-Scholes-Model, which uses a lot of Stochastics (especially Stochastic Calculus) and you should know how to implement some simulation methods (like Monte-Carlo) to actually price specific derivates under that model.
The literature usually highly depends on your level of math skills.

I saw that PBS spacetime youtube video on it, got lost when they added the second level of detectors that somehow proved reverse time travel or something. It was some ivy league college that did the research I think.

I'll do my best, though DESU I don't know all of the answers. Hopefully someone else might.
1. No clue what emits them, but like you said, it's perpendicular.
2. CI explains it by saying that the act of measuring forces each electron's wavefunction to collapse, therby making each electron actually going through one slit, and preventing the interference pattern. PWT says that the measuring device affected the electron's path (in a non-local way, I.E the electron was affected even before the measurment itself) in a way that changed the pattern.
3. not sure buddy
4. try reading about the "quantum eraser" experiment, which did just that. Very interesting results. In the eraser experiment they used quarter wave plates to measure.
5. No. The idea is that both interpertations give different explanations to the same results. They contradict on a basic level (mainly, PWT believes in non-local hidden variables while CI believes in probabilistic outcomes), but in terms of experimental results they predict the same things, at least for now.

1. You can produce them through a variety of methods, doesn't really matter as electrons are electrons. Typically it is done through thermionic emission and/or barrier reduction through application of high electric fields. See Transmission Electron Microscopy (TEM) and electron guns.

With an advanced Field Emission Gun (FEG) which uses a sharpened tip of a specially designed metamaterial (coated tungsten), you can easily produce and tune nA currents with only one electron emitted at a time. Both of these will produce a point source (or spread point source) wave. Nothing produces planar waves, you need to use magnetic optics to produce this effect.


2) You are not quite correct here. If you put a "detector at the slit" (remember that the slit is itself a form of a detector), with the purpose of learning which slit the electron went through, the interference wave will disappear ONLY if the information you extract is 100% accurate 100% of the time. In reality, it is usually less than this so you get a loss of interference which is not complete.

The copenhagen interpretation explains this by the understanding that you cannot simultaneously describe a photon as both all wave and all particle: it is one or the other or a linear combination of the two. By measuring the position perfectly, you collapse the wave function and you have a particle.

3) Any number of methods could be used to attempt to measure the location of the photon in a non-perturbutive manner. They are all complicated, most involve the use of laser light or a clever set up such that the experimenter knows which slit will be used before it is passed.

4) You will destroy the interference pattern.

5) Experiments of Bell Inequality limitations support both the Copenhagen and the De Broglie-Bohm interpretations.


I think you should be asking a more fundamental question however, which is how a single electron can interfere with itself, and if not, how does the effect happen.

>>8915819
>>8915702
So any answer about what is the delta "function" makes you a pseud? I prefer the latter because thinking about functions in terms of shit that only deals with the real numbers is retarded.
