Spherical electron (extra footage)

[@frustumator]

dude, that was amazing. i think this is probably the most in-depth video i've ever seen from you guys! keep up the excellent work, fellas :)

[@AvrahamIshShalom]

Can we get a follow up on this video? I would love to know whether the electrons dipole moment has yet been measured!

[@EebstertheGreat]

+Avraham Ish Shalom The strictest upper bound published so far is |dₑ| < 8.7 × 10⁻²⁹ _e_·cm.

[@AvrahamIshShalom]

Thanks! :-)

[@austinnguyen9107]

u guys know where the papers are?

[@kellyjackson7889]

Moriarty's washroom 'The loo' issue

[@d5uncr]

A new study pushes the sensitivity a magnitude further and it's still a sphere.

[@thefritz123]

Brilliantly clear explanations. Thanks a lot! Hope to see many more videos from Prof. Ed Copeland... .

[@nygeek6471]

please increase the volume!

[@dahauns]

2:35 made me chuckle..."When the experiment is finished, is done perfectly...". "Heh, right." Spoken like a real theoretical physicist! ;-)

[@numspacsym]

Thank you Brady, and thank you Prof. Copeland. Lovely explanation!

[@jessstuart7495]

What is the effective distance the electron's charge is being measured from? Couldn't you have a non-spherical charge distribution at small scales that approaches a spherical distribution at large scales? Analogous to the near-field / far-field pattern of an antenna.

[@Firesoar13]

@jab0805 To better explain Slug's response. These particles are only a small fraction of what makes up matter. Gravity is the physical draw or two objects due to their mass. Items of greater mass have more gravitational pull. Example: a 5" cube of lead has a greater pull than a 5" cube of aluminum. Now an electron has a charge, which can draw protons with their charge, but repel each other. This is what atoms collide instead of fusing. Something that small is beyond the influence of gravity.

[@nottinghamscience]

@wilfred8686 it's a balancing act, but by having extra footage uploaded here to nottinghamscience it helps ease the pressure!

[@chrisofnottingham]

It's interesting that after all the talk about quantum mechanics and how the wavefunction of an electron exists all round an atom at once, when it comes to these measurements the electron is detected as a good old particle in one location.

[@otakucode]

At the point where you mention that they use computers to analyze the experiment data, you show some screenshots of source code (looks like in Visual Studio to me). What source is that? Is that source actually related to the experiment being discussed? Was the source released as part of the research paper?

[@jsullivan05]

I'm really glad you put up these extra footage videos, keep'em comming please :-)

[@Skindoggiedog]

This was amazing. Absolutely loved every second.

[@joelbrown0869]

How is the earths gravitational effects on the electron taken into account in these experiments? Being as small as it is, can I assume the gravity on the earth side of the electron is basically immeasurable from the amount on the far side? How much error is taken into account for the earths magnetism?

[@sumsar01]

Gravity has an immeasurable effect on an electron. We can hardly measure the effects of two neutron stars colliding. My be is that the magnetic field of the earth is also negligible since if the electron is kept in any kind of magnetic trap those magnetic fields would be billions of times larger than earths field..

[@jeebersjumpincryst]

Completely and utterly fantastic!!!

[@chipledorf]

> CP symmetry Chris Hansen would like you to have a seat right there.

[@me835]

@uut0 that sounds like an awesome idea for one of these videos

[@Skindoggiedog]

@4jonah Not weird. Everyone does.

[@judychurley6623]

Any follow-up to this result?

[@mobilisinmobili74]

But if you're talking about charge distribution when you say "the size is 10^-18 meters", how 'much' of it is within that distance? Cause the charge actually extends forever, right; it's like a density curve.

[@michaelroberts8989]

+mobilisinmobili74 the electron orbits in an "orbital", which is where it is found 95% of the time, so they probably define its size as "where you find 95% of the charge of the electron".

[@Pineapple-Lord]

two min thirty sec in; my head is freaking killing me

[@Bobajobimus]

Can you please elaborate on "parity". Usually i can follow follow these pretty well but the equasion madness just confused me.

[@sumsar01]

a parity transformation is a spacial inversion. So in 3D that could be a change from a right-handed to a left-handed coordinate system.

[@kiybro]

The part about covering up the screen in the original video didn't really makes sense, but now I get it, it's about error.

[@rewrose2838]

Bias

[@bl4ck0p]

@Slug99 and that's where string theory comes in trollface.jpg

[@Ethernet3]

Where does the charge of elementary particles come from?

[@sumsar01]

Usually some symmetry in the action/Hamiltonian.

[@xng14]

Is the timecode necessary?

[@jamesmterrell]

WOW

[@xminervaxszf]

i am confused:( overwhelmed and dazzled

[@hookyelyak]

thnx

[@Dyslexic-Artist-Theory-on-Time]

Interesting video! This is an invitation to see an artist theory on the physics of light and time! This theory is based on two postulates 1. Is that the quantum wave particle function Ψ represents the forward passage of time ∆E ∆t ≥ h/2π itself 2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w- function is the same uncertainty we have with any future event that we can interact with turning the possible into the actual!

[@Shoyrou]

Good thing there's wikipedia

"We need to have CP violation." Oh dear. Don't tell the FBI.
