Andrew Briggs - Experiments in Quantum Mechanics

Quantum theory has been the most powerful explanation of how the world, down deep, really works. But quantum theory is weird: things in two states or places at the same time, probabilities not actualities of events, entanglement over vast distances. How do precise, repeatable experiments support such counterintuitive concepts?

Andrew Briggs is Professor of Nanomaterials at the University of Oxford. He is Fellow of St Anne’s College, Fellow of Wolfson College, Fellow of the Institute of Physics, Honorary Fellow of the Royal Microscopical Society, and Member of International Society for Science and Religion and Academia Europaea.

Thank you, great chat. It's a true statement that, without an external force, my bank balance stays the same amount. It's also true to that, relative to external exchange rates, the buying power of that amount, changes constantly.

Quantum mechanics is so utterly fascinating!

[DouglasVoigt-tuxb]

This scientist is getting closer to truth

[leeyan]

Awesome talk, even though my right ear got entangled in quantum vacuum

*This check on your bank balance does not affect your credit score. Only your mood.* 😢

Don't use your energy for anything, just learn from what your energy teaches you.💙💫🙏

Left ear loved it
My right ear is not entangled.

The audio is all at the left channel ... who's mixing ? : )

[mrtienphysics]

The experimentalist was quick not to fall into the false dichotomy trap set up between theory and experiment.

Dude looks like a british intelligent version of Trump 😂

Except the photons from the flashlight hit your hand…

[JayceRenner]

um wut do i know but it sounds like you're describing the andrew uncertainty principle

[clownworld-honk]

When I check my bank statement online it's different to what I perceive as my reality to be so the act of looking at it has induced a negative effect. Must be a quantum thing! 😮

6:32 the microwave pulse will have to directly interact with the system by collapsing it if successful...

Is he trying to say that "wonder" is not important for science? Wow! That's not true. He is assuming that science is always the first cause of science itself. You know we have other subjects to study.

[kencreten]

I cannot believe that this stage of the game... you botched the audio mix and the right channel doesn't

[elsawiegers]

and the sound? got lost in the quantum leap?

[Maxwell-mvrx]

Guys experiences keep out How figure out fundamental unpredictable particles in Quantum mechanic. Science doesnt know How figure out unpredictable particles so far. So guys experiences NOT show up solutions in Quantum particles problems.

FALSE! He still had to know the nuclear spin, which can only be done be measuring it...
