Electron is surprisingly spherical

Electron is surprisingly spherical

The experiment, which spanned more than a decade, suggests that the electron differs from being perfectly round by less than 0.000000000000000000000000001 cm. This means that if the electron were magnified to the size of the solar system, it would still appear spherical to within the width of a human hair.


We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

    nice!

    Not quite sure that this:

    >>> Using a very precise laser, they made careful measurements of the motion of these electrons. If the electrons were not perfectly round then, like an unbalanced spinning-top, their motion would exhibit a distinctive wobble, distorting the overall shape of the molecule. <<<<

    means "round" as much as is does a symmetric moment of inertia. As far as I know the size of the electron is zero in the usual sense. It has intrinsic angular momentum and magnetic dipole moment, but that's not the same thing as saying it occupies volume.

  3. Yeah; not quite sure how to interpret this in light of the “higher education” views of electrons and electron “movement” in atoms and molecules (OTOH, didn’t those psi functions assume infinitesimal size or something?) But I’ll bet “spherical” is not the actual technical finding…

    I agree, “But I’ll bet “spherical” is not the actual technical finding…”

    Popular media drives me crazy regarding science.
    You know, using a very powerful laser” measuring at 10^-12 the size of an electron probably gives the impression to a lot of people that there’s just a fancy laser range finder type of tool that they made. These datas are interpolated (as in over 10 years of data)… We have no idea what this means but certainly isn’t “spherical” in a simple sense. Shape and form kind of change a bit on that scale.

    Reminds me of LIGO, worlds biggest observatory looking for gravity waves… I’ve been there and that’s one “very powerful laser” that measures within “fractions of the radius of a proton”. Basically an interferometer for Galactus. Interesting though, you have to drive less than 2mph there to prevent vibration. (It’s a 4km beam path built into the Earth!) I accidentally went over a speed bump at like 5 mph or something and ruined their current run of data 😮 – embarrassing.

    But 10^-12 of an electron!?!?! This had to be an awesome interferometer. I’d love to see the vibration isolation! This paper I HAVE to read… pretty phenomenal data!
