Reply Dyslexic Artist Theory on the Physics of 'Time' says: June 25, 2018 at 6:27 pm Could it be the potential future and this is waving? This is an invitation to see a theory on the nature of time! In this theory we have an emergent uncertain future continuously coming into existence relative to the spontaneous absorption and emission of photon energy. Within such a process the wave particle duality of light and matter in the form of electrons is forming a blank canvas that we can interact with forming the possible into the actual! The future is unfolding with each photon electron coupling or dipole moment relative to the atoms of the periodic table and the individual wavelengths of the electromagnetic spectrum. As part of a universal process of energy exchange that forms the ever changing world of our everyday life the ‘past’ has gone forever. At the smallest scale of this process the ‘past’ is represented by anti-matter annihilation with the symmetry between matter and anti-matter representing the symmetry between the future and the past as the future unfolds photon by photon. In such a theory the mathematics of quantum mechanics represents the physics of ‘time’ with the classical physics of Newton representing processes over a period of time, as in Newton’s differential equations. In my videos I explain how this process is relative to temperature and the phase changes of matter.

Reply M ß Q says: June 26, 2018 at 11:58 pm I liked the bad news you said in the last two minutes… It made more interested to know more about the quantum mechanics Reply Cre Henge says: July 10, 2018 at 12:29 am Is he high?! He's taaaaalkiiing reeaaallyyyy slooooooooooow…. Reply David Dalmazzo says: July 23, 2018 at 3:49 pm why is it not explained as a dimensional waving form of time? Reply fbabdiver says: August 17, 2018 at 12:49 am so, what would this 2 d chart look like in a 4 dimensional universe? Reply Caleb says: August 26, 2018 at 10:47 pm It wasn't and isn't hard to imagine what is waving. In the example of water, the water is transmitting energetic disturbances. For sound waves, the air is doing the transmitting. For e- in space, one might assume there is an analogous medium that is transmitting the electromagnetic energy, and this was assumed. The name given to the assumed medium was "aether." But it has become forbidden to believe that the aether exists, anymore. Instead, space is said to be truly just space. NOW, it is hard to understand what is waving. Reply Bala Sujith Potineni says: September 26, 2018 at 5:05 pm But what does wave function mean. What does si (x) ata ppint x mean? What is its terminology? And also how is that probability proportinal to si (x)^2 but not si (x)? Reply Şirzat Sayın says: October 8, 2018 at 10:50 pm There is no waving thing, the probability curve looks like wave. Reply 趙元睿 says: November 2, 2018 at 12:20 am from 1:55 you wrote the Schrodinger's Equation wrong, should be (h bar) squared. Reply Brendan F says: November 10, 2018 at 1:49 pm This was amazing!! Please do more with quantum physics! I would love to go really in depth with this style of video. Maybe some practice problems too would be nice. Reply Saleem Shaikh says: November 27, 2018 at 10:57 am Schrodinger couldn't interpret the equation, then Max was born.*wave intensifies* Reply sywaddr11 says: November 30, 2018 at 9:25 pm Born may just part get it right, but original still stands.Electron effects each other with their fields, and probability points out where is the most effected area at that event take place. (Time is an adjective of that event). Reply Karthi S says: December 9, 2018 at 2:53 am wave function is how electron occupies in orbital. it means electron may be distributed like spherical shape or duple shape. this is what I understood. Reply Darian Harrison Ragle says: December 10, 2018 at 7:15 am This is a nice explanation 👌 Reply Andrew Miroshnikov says: January 3, 2019 at 11:27 pm Does anyone know why the square gives the probability density? Reply Ken Hughes says: January 9, 2019 at 10:41 pm The wave function is a function of the way the electron moves through time ! (Faster or slower) This is because time is a wave of energy, varying in energy over duration.

And I don't use this word lightly Reply Albeit_Jordan says: March 31, 2019 at 2:39 pm This might be a very naive question, but how can Schrodinger's equation incorporate Psi if that's the very thing the equation is used to find? Reply Anurodh Kumar says: April 10, 2019 at 2:02 am But que is “How is wavelength from momentum is related with wavelength of wave function”? Reply Vamsi Krishna says: April 20, 2019 at 2:31 am So what exactly is waving when we say electron acts as wave Reply Shashank Sadafule says: April 22, 2019 at 12:56 pm Wow😲😲😲 Reply Josephjmurphy says: June 1, 2019 at 12:16 am Great video, thankyou.

The Problem with Quantum Measurements – Psi (Ψ) The '' measurement problem'' / ''wave-particle collapse'' About one wave measurement of one quantum particle. # There isn't electric wave without quantum particle. The wave-function is result of a real work of quantum particle (h) The wave-function Psi (Ψ) is derivate form of quantum particle. The wave-particle collapse problem could be contemplated as boundary changes of wave and particle simultaneously. # When the wave collapses, the pure electric particle (E=h*f) changes its parameters into negative potential state – Dirac's virtual / antiparticles (-E=Mc^2) and "disappears " in Zero Vacuum T=0K. ===== Reply Qamer Abass says: August 20, 2019 at 10:57 am How photon has momentum????if it is massless… Reply Lambda says: September 20, 2019 at 3:05 am Thank you! Reply The Gee Bees says: September 20, 2019 at 5:28 am How can there be 0 probability of finding the electron at the end of each wave? Wouldn't that mean that electrons traveling at a line somehow skip points in spacetime as if it disappeared then reappeared?

Is it really a specific function as in y=x^2 where you input certain constants and an independent variable? As in e^-x^2 ? If yes, what would it be? Reply Deathbyexile says: October 27, 2019 at 2:04 am The same thing comes up with a deck of cards. When a deck is being shuffled everything is a probability but once a card is pulled the probabilities collapse to be 100% chance of that card being the one pulled. Reply hifellow says: November 4, 2019 at 10:40 pm This was and excellent explanation of Schrodinger's equation. Very good speaker and a clear explanation. Wished he could have addressed what are the dimensions or units of "x". Reply Stan Schurman says: November 5, 2019 at 4:57 pm So far, the clearest explanation I've seen. Reply imgtsmnlom says: November 9, 2019 at 11:33 am It's a bit confusing claiming that the wave function is dependent on x only, uppercase Psi Ψ(x). The actual wave function is dependent on both time and position Ψ(x, t) = ψ(x)ɸ(t), which can be separated into two functions, lowercase psi that is only dependent on x and lowercase phi which is only dependent on time. Otherwise the right hand side of the equation you wrote would always be zero. Reply Nisha Tiwari says: November 17, 2019 at 1:44 am Very elegant explanation.😎 Reply Leave a Reply Cancel reply Your email address will not be published.
