January 12-13th Treeleaf Weekly Zazenkai - Schrödinger's Jinkan

[Jundo]

Today's Little Talk is based on Rev. Jinkan's latest reflections (LINK), and a response which I offered (LINK) ...

Dear All,

Please sit our Treeleaf Zazenkai for 90 minutes with Zazen, Heart Sutra and more:

10am Japan Saturday morning, NY 8pm, LA 5pm Friday night, London 1am and Paris 2am Saturday morning, or any time thereafter here:

However, "one way" live sitters are encouraged to come into the Zoom sitting, and just leave the camera and microphone turned off: Join live (with or without a camera & microphone) on Zoom at: TREELEAF Now OR at DIRECT ZOOM LINK, password (if needed): dogen

00:00 – 00:15 CEREMONY (HEART SUTRA in English) and Dedication
00:15 – 00:45 ZAZEN
00:45 – 00:55 KINHIN
00:55 – 01:25 ZAZEN
01:25 – 01:30 VERSE OF ATONEMENT & FOUR VOWS
01:30 - 01:45(?) Informal Tea Time (All Welcome)

ATTENTION: Everyone, when rising for Kinhin or Ceremonies after Zazen, get up slowly, don't rush, hold something stable, you won't be "late," so TAKE YOUR TIME! Make sure you are careful getting up! [/CENTER]

Gassho, Jundo

PS - There is no "wrong" or "right" in Zazen ... yet here is a little explanation of the "right" times to Bow (A Koan) ...

The other video I mention on Zendo decorum is this one, from our "Always Beginners" video Series:

I also recommend a little Talk on why small rituals and procedures are so cherished in the Zendo:

An article I happened to read soon after Zazen today, just how little the physicists still understand about these Quantum mysteries ...

Dissecting the Quantum Illusion: Debunking the Cheshire Cat Effect

What actually happens is much weirder, and may help us understand more about quantum mechanics.

The quantum Cheshire cat effect draws its name from the fictional Cheshire Cat in the Alice in Wonderland story. That cat was able to disappear, leaving only its grin behind. Similarly, in a 2013 paper, researchers claimed quantum particles are able to separate from their properties, with the properties traveling along paths the particle cannot. They named this the quantum Cheshire cat effect. Researchers since have claimed to extend this further, swapping disembodied properties between particles, disembodying multiple properties simultaneously, and even “separating the wave-particle duality” of a particle.

However, recent research, published recently in the New Journal of Physics, shows that these experiments don’t actually show particles splitting from their properties, but instead display another counterintuitive feature of quantum mechanics — contextuality. ...

... A sequence of measurements on a quantum system will produce different results depending on the order in which the measurements are done. For instance, if we measure where a particle is, and then how fast it is traveling, this will give different results to first measuring how fast it travels, and then where it is. Because of this contextuality, quantum systems can be measured as having properties that we would expect to be mutually incompatible.

“However, we still don’t really understand what causes this, so this is what we wanted to investigate, using the paradoxical quantum Cheshire cat scenario as a testbed,” said Hance.

The team notes that the problem with the quantum Cheshire cat paradox is that its original claim, that the particle and its property, such as spin or polarization, separate and travel along different paths, may be a misleading representation of the actual physics of the situation.

“We want to correct this by showing that different results are obtained if a quantum system is measured in different ways, and that the original interpretation of the quantum Cheshire cat only comes about if you combine the results of these different measurements in a very specific way, and ignore this measurement-related change,” said Holger Hofmann, a professor at Hiroshima University.

Wonderful to practice together again and to chat for a bit afterwards. Thank you, everyone!

In nanotechnology it's a hot topic the emerging properties of materials at different scales. This goes along with that logic.
