Contemporary Physics: Waves of Uncertainty

Explore one of the most important, and misunderstood, concepts in quantum physics: Heisenberg's uncertainty principle.

Please keep trying to educate us masses, @ Perimeter Institute. Just because the material is difficult to understand, I can understand the main ideas with capable teachersl like PI acknowledges. Thank you all.

Excellent explanation of a subject that is difficult for many to grasp! Thank you.

From the observational perspective of our stable structured spacetime experience in which cause always precedes effect and 'things' are separated, we don't understand what QM means BUT if spacetime itself is not fundamental (as is being proposed by several physicists and cosmologists today), maybe stable material patterns are not necessarily stable and the method of modern science-based on deciphering them would have to evolve and become more fundamental.

really informative ❤️ Keep it up. we need this type of easy explanation

I always thought the Heisenberg uncertainty principal was when you decide to manufacture meth to its highest quality..

What if we change the focus from momentum to some other attribute? Are all other attributes similarly uncertain?

[balasubr]

Is there anything unstable or undetermined about a wave? Its more complex than a point but yet not at all fuzzy. To claim otherwise is incomprehensible to me. Sorry

Quantum physics is a mathematic formula based on experiment data. It tells Man’s technology is not advance to see atomic structure at fundamental level. and Their understanding/model of atom is also wrong.
Take slit experiment. If you could see at atomic level and knew structure of photon, then you would see how photon is modulated by slit atom which result in pattern. If you knew correct structure of atom and how it function then you would know position of electron and it’s momentum. You do not. Mankind has quantum and has stopped to look any farther. Every one of you content to be regurgitating what you have been fed, because you have no intention of using your head to see the real nature while you have shiny custom jewelry of QM. There is no space time. There is gravity and matter. You do not know neither of them correctly. Electron dose not decay to claps due to function of nuclei which none of you know and have been too stupid to ask me past 45 years.
