- fractalb 3y ago> 10^-14 * 10^17 = 10^-31 It’s actually 10^3
- 1024core 3y agoTypo: you forgot the "-" before the 17 in 10^17
- AnimalMuppet 3y ago10^-14 / 10^17. Or 10^-14 * 10^-17. Minor nit to an interesting parent.
- A_D_E_P_T 3y agoNot even close. The diameter of the electron is under 10^-18 meters -- that's a sort of experimental upper bound derived from collision experiments -- but it may well be much smaller than that. Some estimates for the diameter of the electron approach the Planck length -- and some, which are no less credible, are well under the Planck length, e.g. at 10^-80m. In physics, the electron is usually described as a point with no size at all. Thus, for practical intents and purposes, it exists but is infinitely small. (Which sort of reflects the notion that human physics is an idealization of the natural world.) The Planck length isn't a hard physical limit for size. It's where direct measurement starts running into insurmountable barriers.
- wrycoder 3y agoWell, 1E-18 / 1E17 is 1E-35, interestingly enough.
