Your Daily Equation #10: Quantum Physics and Probability

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.

This is the reason why directors of sci-fi movies just tag the word 'quantum' when then can't explain a situation 😂😂😂

Heisenberg's uncertainty principle would be a great choice for upcoming days

I’m a teacher myself and I would love to use some of these visualizations during classes, does anyone know where I can get my hands on them?

[priyanshushukla]

Hii prof. Brian, please talk about how the placks constant was calculated and how its idea emerged??

[hussammustafa]

When you discuss schrödinger's equation, you should discuss the time dependent as well as time independent forms of the equation

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.

A single episode like this is enough to think about whole day, in these desperate time.
Thank you Prof Brian.

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?

Sir, Brian, I am writing this from Sri Lanka, being a student of A/L grade 12. I am so long anticipating to have found a person like you, who has an in comparable broad knowledge about physics and psychological physics like quantum mechanics which goes deep inside to the secrets in mind .I am so interest in unveiling the truths behind science which sharpens our perspective about us, our life, our mind and the physical and beyond physical world. today onward I would like to begin my journey with you as one of my teachers and advisers and as one of friends (i know I may be 50 years young to you as i am 17 years old to now)
...i am so eager to untangle my physics questions from you ?my first question I forward you is that Can you explain what is a wave function? (i am asking this because in this video you are explaining quantum physics) does wave function correspond to orbital, three dimensional space which has a highest probability of finding an electron??

Dear Brian Greene,
Have physicists laid down the fundamental foundation for string theory, or do the principles in string Theory still need to be stated?
And do you think there will be a measuring device able to measure such small strings and dimensions?

[mattnewhouse]

If the quarantine goes longer is there time for one on bell's theorem?

[numankaraaslan]

00:00 - 12:40 Well i can understand that.
12:40 - 17:10 Woow, hardcore stuff :)

[_Messiii]

Brian what software do you use to make your videos?

[priyaramakrishnan]

Oh how I wish you had taught me my physics class in college!

[amaljoy]

I think it would be better to discuss more interpretation of quantum mechanics

[bruceneeley]

Isn't a measurement a snapshot in time requiring an observer, thus reducing probability to subjectivity?

[miladkhoshnaw]

Professor Greene, did the the large hadron collider in Europe proved that the fragments of the collision particles moved to extra dimension ? Thank you

[shouvikmondal]

What will happen to us if we are able to find out the theory of everything?

[scottc]

The sound of your voice describing the foundations of our existence is comforting during this time of isolation. Thanks for doing this.

Hi sir, This is Mohammed Asif from occupied Kashmir, I want a video about the sentence used by Einstein in Quantum Entanglement, "Spooky Action at a distance".
I'm following you since I was 17...
I also emailed you about 3 years ago but I got no response, as know you may be busy with your research....
Thnx, & love you!

Probability is a concept wrapped in a formula used to explain what we cannot yet, for certain, specify (for the record, I want credit for that statement... 😎). I dislike probability, as it only tells us the likelihood of where a particle should be, but I get it... I am science guy searching for absolutes, and probablties make me "itchy"... *This* is why I love quantum physics so
