Toot

Written by Richard Littler on 2025-01-30 at 08:49

As I was going to the shower, I tossed a bundled pair of socks from my office doorway onto my desk.

After my shower, I couldn't find the socks. Not on the desk, chair or floor...

I eventually found them (steeping) in my full tea cup.

Good morning.

@Richard_Littler So new carrier in ball tossing? You seem to be pretty accurate in hitting the obvious target. 😄

@Richard_Littler Those textile tea sieves are called "Teesocke" in colloquial german.

@Richard_Littler might be better to put milk in your tea. But nice throw, mind :)

It only requires a slight modification (from "Chitty Chitty Bang Bang")...

Steep in time, steep in time

Never need a reason, never need a rhyme

Steep in time, we steep in time

@Richard_Littler

Yeah, I've found the laws of physics don't actually apply unless you watch where something falls.

(But usually my missing things have been kidnapped by cats. And then chewed by dogs...)

ELI5: The Double-Slit Photon Experiment

Briefly, in the early 20th century, people like Rutherford, Planck and Einstein had competing theories as to whether light was fundamentally a particle or a wave. Thomas Young had performed the double slit experiment by showing that light that passed through two slits resulted in an interference pattern on the detector screen. This is analogous to dropping two stones in a perfectly calm lake. Waves will recede from each stone's landing spot, until the waves collide with each other. Wave crests will collide with other crests, causing supercrests, and troughs will collide with troughs, creating supertroughs (as long as the waves are in phase, which they would be in you dropped the stones at the same time). This pattern of supercrests and supertroughs is called an "interference pattern". When Young saw an interference pattern on the detector screen, he declared that light behaved in the exact same way as water waves do, and therefore, light is fundamentally a wave.

However, Max Planck had shown that whether light was a wave or not, it existed in discrete packets called quanta. Like a case of beer is divided into 24 beer-sized quanta, you can't have a case of 24.6 beers.

So they were able to repeat the double slit experiment but this time they fired individual quanta of light through the slits, without looking to see which slit the quanta went through. They observed little dots on the screen, representing each quanta of light.... so... particle? Except when they kept firing quanta of light through the slits, the individual dots accumulated to form the same interference pattern that Young saw. This was extremely counterintuitive, because it doesn't seem possible that individual quanta of light could produce such a pattern. How could it? This result suggested that the individual quanta of light were interfering with themselves, and therefore must pass through both slits at the same time.

So they decided to add a detector at one of the slits and see which slit the light is going through. To their amazement, when they did this, the interference pattern disappeared, and light clearly passed through one slit or the other, and just showed up on the detector as individual dots with no pattern. So... what?!?

They removed the detector and sure enough, the interference pattern returned. In conclusion, light appeared to behave as a wave, even individual quanta of light, since it appears to pass through both slits simultaneously, which is necessary for the appearance of an interference pattern. When you measure which slit the light when through, light appears to behave as a particle, and just flies through one slit or the other, but not both.

The act of observing the experiment changed the result. So light can be described successfully as both a particle and a wave. As it turns out, all matter can be described this way, not just light. This was a tipping point for a new understanding of the universe through quantum mechanics, which is a whole different story.

TL;DR Light is a wave, unless you look at it like a particle, then it's a particle, but also it's a wave. Simple.
