Episode 10 #YourDailyEquation: The revolutionary new idea of quantum mechanics is that reality evolves through a game of chance described by probabilities. In today's episode of Your Daily Equation, Brian Greene explains the origin of this iconic quality and describes the equation that expresses it mathematically.
Even if your math is a bit rusty, join Brian Greene for brief and breezy discussions of pivotal equations and exciting stories of nature and numbers that will allow you to see the universe in a new way.

Where the probability spikes to 1 (or near 1) is a point of resonance. Working with electronics and radios tuning a radio (or for that matter a control loop) the spike is where the resonance occurs or called a 'pole' in the controls world where the feedback is feeding back on itself generating a resonance (in the Laplace world). So using that model a wave collapse is a resonance point in probability. I have to think about that one.

A wavicle is a quantum particle. I like to visualize it as a pulse in a wave function. The wave being a function of energy in the field that it exists and the particle's edge beginning where the wavicle noticeably begins to increase in amplitude and ends in amplitude. I say noticeably because the field is fluctuating everywhere in very small amounts so the edges of the wavicle are unclear. Does this sound like a workable model?

@mrnarason 4 жыл бұрын

I've been learning differential geometry lecture series that the wave function is not a complex-valued function over the reals. Idea that Psi: R^d -> C. But what if Psi is a section of C-vector bundle over R^d? Locally, the wave function looks like a function over R^d. What is the bundle of interest when dealing with arbitrary changes of coordinates? Of course the frame bundle. If you have a frame bundle, you can establish a connection on the frame bundle. If you have a connection, you can define a covariant derivative on the sections of any associated bundle. Then you have a covariant derivative acting on the wave function. sections of such an associated bundle are represented as C-valued functions, not on the base space but on the total space of the principal bundle. So rather than saying Psi is a section of this associated bundle with fiber C, Psi is a complex-valued function, not on R^d but on the total space of the principle bundle.

If world is just quantum probability, how come i can watch this video than? Correct me if I'm wrong but we never see protons and neutrons, things are the way Mr. Green described. Why do we see distance, would be more natural if light could extend picture as a box, so we would always look at things as staring directly into a wall. Because light are waves of energy, spreading from their source, those waves extend before picture of an object reach our eyes. But this is not how we see, we can't observe electrons, our eyes are electrons where tinny packets of EM vibration hit light sensitive cones in our eyes. This is how i imagine collapse of electron into a single dot, electric wave hit my eye cones, electron is converted into a electric pulse and they all merge in my head into a consistent illusion of reality. Good video, they should teach this stuff in primary school all around the globe.

For example, we know an electron behaves in a quantum manner, so what if we keep incrementally testing bigger and bigger "particles" say a proton, an atom, a collection of atoms etc.. is there a way to determine a switch over point as to when matter starts behaving in a Newtonian way, or when it behaves in a quantum way. Hope my question makes sense. Thanks...

What if you keep shrinking the billiard ball smaller and smaller, at some point when you get down to the size of particles it starts to show this probabilistic nature.

But the probability wave is nevertheless a real wave defined by the oscillatory unit (i) squared, that gives you negative 1, meaning that its polarity oscillates in the instance of its squaring. What is so exiting about a QM wave is that though it's imaginary it's also a real one and the purpose of complex conjugates is to return the real numbers.

I respectfully offer a different view of the double slit experiment which should be called the triple barrier experiment. Matter is basically energy and any matter "particle" is an energy bundle. In this specific experiment the "particle" rides the ripples, caused by the triple barriers, in the expansion of spacetime. The "particles" are decoupled from "time" since the ripples in spacetime are always there. The "particles" can pass the triple barrier in groups or singly with much "time" separation and still produce the interference pattern. This discussion does not include the measurement anomaly problem.

If anything, we can probably say that probabilities is probably the nature of reality. But as soon as we observe or measure anything, then reality is no longer probabilistic, as it is what you measured or observed. In other words, since quantum physics is purely dealing with probabilities, quantum physics is just as likely to be not probable at all.
