In phonetics, aleph /ˈɑːlɛf/ originally represented the glottal stop ([ʔ]), often transliterated as U+02BEʾ, based on the Greek spiritus lenisʼ, for example, in the transliteration of the letter name itself, ʾāleph. Even in early use, it occasionally functioned to indicate an initial unstressed vowel before certain consonant clusters, the prosthetic (or prothetic) aleph. In later Semitic languages it could sometimes function as a mater lectionis indicating the presence of a vowel elsewhere (usually long). The period at which use as a mater lectionis began is the subject of some controversy, though it had become well established by the late stage of Old Aramaic (ca. 200 BCE).
Aleph is a 2011 novel by the Brazilian writer Paulo Coelho. It is the fourteenth major book by Coelho, and touches on the theme of spirituality. Aleph was written in Coelho's native language, Portuguese. Under the sentence "Some books are read. Aleph is lived", the book is an autobiographical account written in a novel format. Upon release it became a bestselling novel in Brazil.
Plot
When the writer feels that his attempts are not properly being requited with the results he desired, he starts to have doubts about the path he is following and about the things he is doing. Then, as his master J. says, he starts trying to become the "King of [his] Kingdom". The master J. tells him that what the writer is feeling is what he himself had felt some years back. That way, the writer is convinced that what he is in is a phase he cannot withdraw himself from and then he goes to travel.
The writer persuades his agent, and then makes out a way to visit Russia for his tour, on the pretext of signing books and holding various programmes for the promotion of his books in the northern Eurasian parts. In Russia, he comes across a girl, Hilal, who happens to be a Turk. She talks about her dream about a friend with a light and so does the story develops. Hilal also joins the writer in his carriage in the train. Then, in a vestibule, the two of them, the writer and Hilal see Aleph, which is defined as "a point where everything, the whole universe is contained".
Fady Abi Saad, in Arabic فادي أبي سعد (born June 7, 1980), better known by his stage nameAleph Le Piano De L'orient, is a Lebanese pianist, composer, arranger and entrepreneur. He is the owner and Art Director of 8ͤ Art Entertainment.
Background and education
Aleph was born in Ehmej, Lebanon. He discovered music at the age of 3 when he was given a small old wooden piano. Reconstructing familiar tunes from such an early age, he was able to grasp occidental melodies while oriental tunes eluded him. He persevered and finally discovered what was missing: the "quarter tone", a basis of oriental music. His parents who saw his potential finally got him his first “real” piano.
Passionate about sounds, Fady Abi Saad wanted to express Oriental melodies through an Occidental instrument, the piano, with no artifice or subterfuge. During the Lebanese Civil War, Aleph and his family left their hometown for the mountains to seek peace. Aleph spent all of his time in his uncle's studio. His uncle Michael Ramia is a composer who had mastered more than 8 instruments and has been a great influence on him. His days were dedicated to training and entertaining, being the main attraction at all family festivities alongside his cousin Carla Ramia which sang Arabic at an early age, and does so till present day.

Comparing a precise measurement of the muon magnetic moment with its theory prediction it is possible to check whether our world is accurately described by the Standard Model of particle physics, a theory that has been extremely successful so far, or whether there is a difference between the experimental measurement and the theory prediction that is caused by yet unknown particles or forces.

2HDM in light of the CDF W boson mass and the muon anomalous magnetic moment (Jeonghyeon Song)
Title: 2HDM in light of the CDF W boson mass and the muon anomalous magnetic moment
Speaker: Jeonghyeon Song (Konkuk University)
Meeting: Physics beyond the Standard Model in light of the CDF W boson mass anomaly [https://indico.kias.re.kr/event/130]
Date: Friday 24 June 2022
Abstract: The recent W boson mass measurement by the CDF collaboration with unprecedented precision indicates a significant deviation from the standard model prediction. This has profound consequences in searching for physics beyond the SM. In the framework of two-Higgs-doublet models, we study the effect of the new W mass measurement on the parameter space. We impose other constraints, including theoretical requirements, flavor-changing neutral currents in physics, the cutoff scale above 1 TeV, Higgs precision...

US-based Physicists Tout ‘Watershed Moment’ in Particle Research
Project could change scientists’ understanding of particle physics and the very fabric of the universe

How Can the Measured Number of Neutrino Species Be 2.9963 +- 0.0074?
The quarks and leptons of the Standard Model of particle physics are arranged into 3 families with identical interactions, yet nobody knows why. This fact makes us wonder if there could be additional families of quarks and leptons that we haven't discovered yet. Each of the known families has a neutrino as its lightest particle. Thus, it makes sense to experimentally determine how many types of neutrinos there are in the universe.
Here, we look at how particle physics experimentalists measured the number of light neutrinos. These measurements were done by the ALEPH, DELPHI, L3, and OPAL experiments at LEP, the Large Electron-Positron Collider. LEP operated at CERN from 1989 to 2000, and occupied the space now used by LHC, the Large Hadron Collider.

Meeting: Physics beyond the Standard Model in light of the CDF W boson mass anomaly [https://indico.kias.re.kr/event/130]
Date: Friday 24 June 2022
Abstract: The recent W boson mass measurement by the CDF collaboration with unprecedented precision indicates a significant deviation from the standard model prediction. This has profound consequences in searching for physics beyond the SM. In the framework of two-Higgs-doublet models, we study the effect of the new W mass measurement on the parameter space. We impose other constraints, including theoretical requirements, flavor-changing neutral currents in physics, the cutoff scale above 1 TeV, Higgs precision data, and direct collider search limits from the LEP, Tevatron, and LHC experiments. We find that upper bounds exist on the masses of the heavy Higgs bosons. And type-II and type-Y in the inverted scenario are completely excluded. Simultaneous explanation including the muon g-2 and lepton flavor universality data is also discussed in the Higgs-phobic type-X.

LEP operated at CERN from 1989 to 2000, and occupied the space now used by LHC, the Large Hadron Collider.
Here, we show how the number of light neutrinos affects the production and decay of the Z boson. We discuss the measurements that allowed physicists to extract the number of light neutrinos and explain why the measured result is not an integer.
The result was compatible with the number of neutrinos in the Standard Model of particle physics: 3 (the electron, muon, and tau neutrinos).

Particle physicists seem to constantly announce discoveries which then disappear. What is going on? How seriously are you to take the recently announced Fermilab muon g-2 anomaly or the B-meson anomaly at the Large Hadron Collider? In this video I explain what's going on.

I have a longer comment about the recent muon g-2 measurement here:

Addendum to what I say at 5 mins 30 seconds: That's only for a normal distribution. The relation between confidence level and standard deviation can differ for other distributions.
Correction to to what I say at 7 mins 18 seconds ("had no known interpretation"). This only refers to the superjets, not to the pentaquarks (which, well, were interpreted as pentaquarks). Sorry about that.

In phonetics, aleph /ˈɑːlɛf/ originally represented the glottal stop ([ʔ]), often transliterated as U+02BEʾ, based on the Greek spiritus lenisʼ, for example, in the transliteration of the letter name itself, ʾāleph. Even in early use, it occasionally functioned to indicate an initial unstressed vowel before certain consonant clusters, the prosthetic (or prothetic) aleph. In later Semitic languages it could sometimes function as a mater lectionis indicating the presence of a vowel elsewhere (usually long). The period at which use as a mater lectionis began is the subject of some controversy, though it had become well established by the late stage of Old Aramaic (ca. 200 BCE).
