Solution to #Feynman's #reversesprinkler puzzle also applies to "silly sprinklers"
Some suggested that if the friction was low enough and the inflow rate high enough, a reverse sprinkler would start to turn in the opposite direction of an ordinary sprinkler, thanks to the formation of a vortex inside. Experiments have been all over the place: some showed steady reverse rotation, some showed only transient rotation and some produced unsteady rotation that changed direction

Alright, future engineers!
**Feynman Technique:** Explain a tough concept in simple terms, like you're teaching it to someone with no prior knowledge.
Ex: Walk through a tricky thermodynamic problem solution out loud to an empty chair.
Pro-Tip: Stumbling shows gaps! Revisit, re-explain until it's crystal clear. True understanding achieved.

🎩🤖 Ah, the classic "AI will fool you" diatribe – because clearly, #Louwrentius has cracked the code on human gullibility! If only #Feynman were here to remind us that we're not "fooling ourselves" but rather being entertained by our own #digital #puppets. 🧠🎭

The #math of choosing a #restaurant is revealed in #RichardFeynman’s notes
Each restaurant is assigned a score to indicate its quality. Aim is to maximize score added up over a given number of nights of dining.
#Feynman found an equation for threshold against which you compare best restaurant you’ve tried so far. Each night, you check your favorite against it. If your fave scores above, return to it for remaining nights; if not, try somewhere new.

A quotation from Richard Feynman
It doesn’t seem to me that this fantastically marvelous universe, this tremendous range of time and space and different kinds of animals, and all the different planets, and all these atoms with all their motions, and so on, all this complicated thing can merely be a stage so that God can watch human beings struggle for good and evil — which is the view that religion has. The stage is too big for the drama.
Richard Feynman (1918-1988) American physicist

Alright, future engineers!
**Feynman Technique:** Explain a complex concept simply, as if to a 5-year-old.
Ex: Teach a tough derivation to your pet.
Pro-Tip: If you can't simplify it, you don't fully understand it yet! It reveals your knowledge gaps.

One Electron, Threaded Through Time
In the spring of 1940 the telephone rang in the graduate residence at Princeton, and Richard Feynman, then a doctoral student, picked it up to hear the voice of his advisor, John Archibald Wheeler. Wheeler skipped the greeting. He had solved a mystery no one else had thought to name, he said, and he knew why every electron in the universe carries exactly the same mass and exactly the same charge. The answer was that they are all the same electron. […]https://bolesblogs.com/2026/07/01/one-electron-threaded-through-time/

One may read this [1] side by side with the #EpistemicHumility point by #Feynman [2]:"Our #freedom to #doubt was born out of a struggle against authority in the early days of #science. It was a very deep and strong struggle"
"If we suppress all discussion, all criticism proclaiming “This is the answer, my friends; man is saved!” we will doom humanity for a long time to the chains of #authority, confined to the limits of our present imagination. It has been done so many times before" [2]

A commentary [1] reminds how fast science and research may backslide when freedom backslides.An idea so old: replacing "peer review with the judgment of nonexpert political appointees" towards "complete political control of science" [1]
This made me think again about liberty (John Stuart Mill: https://hostux.social/@dderigo/112968366827427191) and #EpistemicHumility (as #Feynman [2] frequently reminded: https://hostux.social/@dderigo/112955785815324476) as a key horizon never fundamentally introjected, periodically on the brink of the abyss

It amazes me that watching the #Feynman lectures, 50+ years old, and he is talking about the same questions we have today. Entropy, Emergence, Quantum uncertainty, weakness of gravity and many more. We think we are all that but looking back, we still have the same questions Einstein and Heisenberg dug up at the turn of the century.

If #infinity, #Feynman only begins to 🤯🤯🤯 your head! 😹😹😹 #Aatman. Omnipresent. Light is closest to Aatman that we can experience by form. Reason Feynman is correct-ish, think he would agree-ish 😹😹😹, is Aatman is all pervaded so no such thing as time or space at all. #SpaceTime #Quantum #Physics

**Feynman Technique:** Explain tough concepts simply, as if teaching a child.
Ex: Describe how a transistor works without jargon.
Pro-Tip: If you can't simplify it, you don't fully understand it. Highlights your knowledge gaps!

I actually wrote a blog post some time ago along similar lines, using the #Feynman method to treat #writing as a tool for exposing gaps in understanding and refining it iteratively:

İnsan Nedir? sorusunun cevabını araştırmaya 2012 yılında başlamıştım
Çünkü ondan önce Âllah'ı araştırmaya kalkmış ve başaramayacağımı anlayıp, önce "kendimi anlamaya, bilmeye" yönelmiştim
Duyular başta olmak üzere İnsanı oluşturan her şey hakkında araştırmaya başlamıştım.
İnsan bedeni %70'lere kadar çıkabilen oranda SU olduğu için suyu da araştırdım.
SU Feynman'ı da hayret ettirmiş!

Mıknatıslar Neden ÇALIŞIR? Feynman'ın Açıklamayı Reddettiği Tek Soru
Richard Feynman'ın 1983'teki efsanevi BBC röportajından ilham alan bu videoda; fiziğin neden "neden" sorusuna değil de "nasıl" sorusuna cevap verdiğini ve neden tanıdık açıklamalar beklemenin sizi her zaman tatminsiz bırakacağını inceliyoruz.
Manyetizma Zamanın geriye akmasıdır!
