Czeslaw Milosz - Encounter (zen reading)
Encounter
(Czeslaw Milosz - 1936)
We were riding through frozen fields in a wagon at dawn.
A red wing rose in the darkness.
And suddenly a hare ran across the road.
One of us pointed to it with his hand.
That was long ago. Today neither of them is alive,
Not the hare, nor the man who made the gesture.
O my love, where are they, where are they going
The flash of a hand, streak of movement, rustle of pebbles.
I ask not out of sorrow, but in wonder.
My take: whether intended or not, this is a magnificent artistic representation of the Mahayana Buddhist concept of sunyata (creative emptiness - impermanence), the poetry version of a masterful zen painting, an immersion into the wonder of Buddha-nature.

Scoala cu clasele I-VIII Florin Comişel - Ploieşti (Middle School Florin Comişel)
That's the school where I was a student in grades 1 through 4 (from 1970 to 1974).
At that time, the school name was plainly "General School Number 11". Every school recess happened in the Jupiter 6 backyard: then it seemed huge to me (although over the years my perception changed). Still, the school was very close to my home (I used to live on Jupiter 2). My classroom teacher was Mrs. Elena Nedelcu, a kind, family-oriented person.
Later, the school name changed to Florin Comişel Middle School.
Florin Comişel (1922-1985) was a Romanian composer, pianist, and director.
In context (and speaking of music): in 1972, just around the time when I was finishing the second grade, Elton John released Rocket Man.

Agnosticism/atheism and the underlying zen
To be agnostic in the sense of "I don't want to get involved" or "I am sitting on the fence" is not a tenable position. It is incomplete in that it begs for a follow-up. However, most of those claiming an (operational) agnosticism are implicitly pointing out to a (philosophical) atheism.
Otherwise, only "sitting on a fence" would implicitly recognize a certain region bounded by that fence.
But there is no fence.
And here is the zen.

Over the Hills and Far Away - my favorite LZ and why
In the night that preceded my departure to America (August '92), I obsessively listened, for hours and hours, Led Zeppelin's "Over the Hills and Far Away". This LZ piece remained with me forever!
"Many dreams come true, and some have silver linings"...

(Non-)apologia lui Calistrat
Ce avem aici e in esenta e vorba de un textbook "non-apology apology". Aparent Calistrat Chifan isi cere scuze (printre rinduri) pentru datul de palme - "brutal" e termenul lui Chifan pentru ceea ce s-ar putea califica drept "battery" (penal/criminal) in sens legal (a se contrasta cu victimele, care nu au comis nicio crima - in cel mai rau caz ar putea fi incalcarea conventiilor establishment-ului, care nu e o crima).
Textul lui Calistrat se desfasoara ca un text defensiv, cvasi-submisiv fata de ierarhie. Insa pentru marele public e un ghiveci pasiv-agresiv, o apologie ne-genuina - ceva in gen "fratilor, imi cer scuze pentru greselile mele, apreciez suporterii publici, *dar* cei ce au remarcat greselile mele sint dusmanosi, tendentiosi si bintuiti de un suflu de rautate" (!).
Fragmente din declaratia de la "botul calului" (pagina calistrat dot ro):
- După prima săptămână de post al bucuriei, am putut
străbate cu mintea printre avalanșele de insulte care de care mai dure și mai
pătimașe.
- Cuvinte grele, replici dure, tot felul de confecții
verbale răutăcioase izvorâte din prisosul unor inimi pline de dreptate,
justiție, adevăr, sau păreri bine construite în ceea ce privește o faptă
negheobă săvârșită la un moment de neatenție și neluare aminte. [...]
- Scuzele nu folosesc la nimic, fapta este incalificabilă și
demnă de pedeapsa primită, atât din partea superiorilor, a publicului, a
societății consternate de un gest injust, pe fondul unor ambiții feminine,
provocate în formă continuă, instigând la dezordine în timpul slujbelor, însă
raportate la persoana mea, omul iute și neatent în momentul nedorit, s-au
petrecut cele știute.
- Simt că lecția de la Dumnezeu, a fost cu scopul de a vedea că sunt om cu slăbiciune și pot cădea în ispită, dacă nu am trezvie în minte.
- Acum cu mintea limpede, fără a mima vre o umbră de smerenie, sincer îmi asum întreaga greșeală petrecută, peste care poate s-ar fi putut păși în cu totul vre o altă formulă.
- Mulțumesc deopotrivă creștinilor firești și obișnuiți, care au luat lucrurile așa cum sunt, apoi celor care au ales să se roage păstrând tăcerea [...]
- Nu este doar vina mea personală, chiar o parte din "media", și-a adus un aport deosebit prin metodele ei clasice de destorsionare a realității lucrurilor, să facă dintr-un călugăr obișnuit, un personaj de carton, un impostor, un pericol public, un personaj negativ al societății. [...]
- Într-adevar, de la acest incident izolat, care se putea întâmpla oricui, nu neapărat numai mie personal, s-a creat un suflu de răutate inimaginabil de tendențios și dușmănos, în mod inexplicabil, care a cuprins intreaga suflare. [...]
(Pr.Calistrat).
De aceea ceea ce avem aici are sens NUMAI ca un produs specific directionat pentru consumul si satisfactia celor sus-pusi ierarhi bisericesti. Care sint de fapt cistigatorii in toata afacerea asta.
C-asa-i in tenis.

Yitang Zhang - the genius who prevailed
Pe scurt - viata unui geniu matematic - Yitang Zhang - care a suferit multe obstacole, faultari si a trecut prin multe perioade dificile. Sint foarte bucuros ca a reusit.
https://en.wikipedia.org/wiki/Yitang_Zhang
Zhang's PhD work was on the Jacobian conjecture. After graduation, Zhang had trouble finding an academic position. In a 2013 interview with Nautilus magazine, Zhang said he did not get a job after graduation. "During that period it was difficult to find a job in academics. That was a job market problem. Also, my advisor [Tzuong-Tsieng Moh] did not write me letters of recommendation." Zhang made this claim again in George Csicsery's documentary film "Counting from Infinity: Yitang Zhang and the Twin Prime Conjecture" while discussing his difficulties at Purdue and in the years that followed. Moh claimed that Zhang never came back to him requesting recommendation letters. In a detailed profile published in The New Yorker magazine in February 2015, Alec Wilkinson wrote Zhang "parted unhappily" with Moh, and that Zhang "left Purdue without Moh's support, and, having published no papers, was unable to find an academic job". In 2018, responding to reports of his treatment of Zhang, Moh posted an update on his website. Moh wrote that Zhang "failed miserably" in proving Jacobian conjecture, "never published any paper on algebraic geometry" after leaving Purdue, and "wasted 7 years of his [Zhang's] own life and my [Moh's] time". After some years, Zhang managed to find a position as a lecturer at the University of New Hampshire, where he was hired by Kenneth Appel in 1999. Prior to getting back to academia, he worked for several years as an accountant and a delivery worker for a New York City restaurant. He also worked in a motel in Kentucky and in a Subway sandwich shop. A profile published in the Quanta Magazine reports that Zhang used to live in his car during the initial job-hunting days. He served as lecturer at UNH from 1999 until around January 2014, when UNH appointed him to a full professorship as a result of his breakthrough on prime numbers. Zhang stayed for a semester at The Institute For Advanced Study in Princeton, NJ in 2014, and he joined the University of California, Santa Barbara in fall 2015.

Encounter at Farpoint
Star Trek TNG's pilot episode "Encounter at Farpoint" (1987) concluded today on Heroes and Icons HD.
Wonderful. It's a must see, but for everybody I paste here the plot from Wikipedia https://en.wikipedia.org/wiki/Encounter_at_Farpoint
In 2364, the new flagship of the United Federation of Planets, Starfleet's USS Enterprise, travels to the planet Deneb IV for its maiden voyage. Enterprise is to open relations with the simple Bandi people who have somehow been able to tap immense energy reserves and construct Farpoint Station, much to the surprise of the Federation. En route, the Enterprise is met by an omnipotent being who identifies himself as Q, a member of the Q Continuum—posing in appearance as a Grand Inquisitor—who declares that humanity is being put on trial then decides that their actions in their upcoming mission will be used to judge their worthiness and determine their fate as a race. Before letting the ship resume its course, Q warns Captain Picard (Patrick Stewart) that he is destined to fail. As the Enterprise arrives, the crew members explore the offerings of Farpoint Station and establish relations with their Bandi host, Groppler Zorn (Michael Bell). The crew becomes suspicious when items they desire seem to appear out of nowhere moments later, and are unable to identify the power source that feeds the station. Deanna Troi (Marina Sirtis), an empath, senses a being with powerful yet despairing emotions nearby, and the crew discover a strange labyrinth beneath the station, but Zorn does not offer an explanation. As the Enterprise crew continues its explorations, a large unknown alien craft enters orbit and begins to fire upon an older Bandi settlement near Farpoint Station, and abducts Zorn. Before Picard orders the ship's phasers to be fired at the craft, Q appears to remind him of humanity's trial and prompts Picard to send an away team to the alien craft. The away team discovers the craft has passages similar to those under Farpoint and they are able to free Zorn. Their actions cause the alien craft to transform into a jellyfish-like space creature, and Picard is able to deduce the mystery of Farpoint Station. He confirms with the apologetic Zorn that the Bandi found a similar lifeform injured on their planet and, while attempting to care for it, they also exploited its ability to synthesize matter to create Farpoint Station. The creature now in orbit is trying to help free its mate by attacking those who hold it captive. Though Q goads Picard into punishing the Bandi, Picard refuses, instead ordering the Enterprise to fire a vivifying energy beam onto Farpoint after the station is evacuated. The beam allows the land-bound creature to transform back into its jellyfish-like form, and it flies into orbit to join its fellow being. As the crew watches the reunion of the alien creatures, Q reluctantly tells Picard that the humans have succeeded in their test, but hints that they will meet again.

A response to Londregan and Klainerman - The Princetonian 9/22/21
Good reading, especially as a complement to the discussion notes that appeared on this blog - see "White Math" or Sergiu Klainerman's straw man - excerpts from a discussion. The feeling is similar, the author of the opinion piece in The Princetonian rightfully seeing false equivalencies where some Romanians saw the straw man:
"When we refuse to give grace by listening fully to the voices of others, especially historically marginalized voices, we make the same mistake as Londregan and Klainerman. We shout over and misrepresent voices we dislike. We seek false equivalencies rather than truth."

Rest in peace, my beloved Copperetta (April 14, 2004 - September 20, 2022)!
Towards the end you suffered a lot (being blind and deaf for more than one year) but you still cleverly learned a daily routine and stayed close to us, on the sofa (which you always managed to find), purring continuously!
No more suffering, my love!
You lived a full life of more than 18 years and will remain forever in our hearts! Thank you for everything!

Abhay Ashtekar on Gödel Universes, Buddha's Poison Arrow, Time Travel, and Loop Quantum Cosmology
Abhay Ashtekar - from Wikipedia - https://en.wikipedia.org/wiki/Abhay_Ashtekar
Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist. He is the Eberly Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. He has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a legendary 1974 prediction by Hawking. Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all the attempts at 'quantizing' general relativity." Ashtekar was elected as Member to National Academy of Sciences in May 2016.
Abhay Ashtekar is an atheist, though he enjoys reading on Indian and other eastern philosophy, namely the Tao and the Zen traditions. Furthermore, he believes to be inspired from the Bhagawat Gita as regards his attitude towards work.

Memories from ONU
Until not long ago, these cannons were placed in front of the Meyer Hall of Science.
At some moment in the early 2000s the Physics Dpt had a plenary talk by Gerardus 't Hooft, Dutch Nobel Prize winner. As I was interested by some entanglement problems, I tried to present our distinguished speaker some of my thoughts. I was talking to him along the road from the dining area to Meyer, and as we passed the cannons, he stopped for a while, looked at the cannons and told me he felt that the presence of such symbols in front of a university building was not a nice combination, since it reflects hostility. Honestly I did not pay much attention to the cannons, but I agreed with him.
Recently they were moved near a lake on campus (pictured here).

Poetry by Ryōkan Taigu (7 Haiku Poems)
Ryōkan Taigu (良寛大愚) (1758–1831) was a quiet and unconventional Sōtō Zen Buddhist monk
Ryōkan Taigu of Japan (18th century), was a quiet, eccentric Zen Buddhist monk whose name means "broad-hearted generous fool", qualities that his life and work embodied. Ryokan didn’t like to be considered a "poet." He once said “When you know that my poems are not poems, Then we can speak of poetry”. The form of poetry Ryokan practiced so perfectly reflected his life - clear, present, simple and disciplined. It is inspired by nature, his daily chores, lonely winters, begging for food and playing with the local village children.

Maggie (2003-2022)
Just after her 19-th birthday...
RIP my love!!!
Maggie (2003-2022). Till we meet again!
Maggie lived a full, complete life. She got a litter of four, O'Malley, Dusty, Copperetta, and Mixie (the last two are still living, quite ancient themselves). In human years, Maggie definitely got to be more than 90 years old. In the last days of her life she was extremely weak and thin, yet carried on like a true and brave samurai! In the day prior to her passing, she gathered all her strength and will power, jumped over a tall window, got outside, and waited for us to come from school in the sunlight of a beautiful day. If Maggie would be a painting, I could not characterize her otherwise than a masterpiece.
