A Solution of the Cosmological Constant and DE and Arrow of Time, Using Model of a Nonsingular Universe from Rosen from Volume (56) Ettore Majorana International Science Series, Physics, 1991

We reduplicate the Book “Dark Energy” by M. Li, X-D. Li, and Y. Wang, given zero-point energy calculation with an unexpected “length’ added to the ‘width’ of a graviton wave just prior to specifying the creation of ‘gravitons’, using the Rosen and Israelit model of a nonsingular universe. In doing so we are in addition to obtaining a wavelength 10^30 times greater than Planck’s length so we can calculate DE, may be able to with the help of the Rosen and Israelit model have a first approximation as to the arrow of time, and a universe with massive gravity. We have left the particulars of the nonsingular starting point undefined but state that the Rosen and Israelit model postulates initial temperatures of 10^-180 Kelvin and also a value of about Planck temperature, at 10^-3 centimeters radii value which may satisfy initial conditions asked by t’Hooft for describing an arrow of time. A key assumption is that the DE is formed at 10^-3 cm, after an expansion of 10^30 times in radii, from the Planck length radius nonsingular starting point. The given starting point for DE in this set of assumptions is where there is a change in the cosmic acceleration, to a zero value, according to Rosen and Israel, with time t = 1.31 times 10^-42 seconds. Which may be where we may specify a potential magnitude, V, which has ties into inflaton physics. The particulars of the model from Rosen and Israelit allow a solution to be found, without discussion of where that nonsingular starting point came from, a point the author found in need of drastic remedies and fixes.

The quest for scientific culture

What exactly is “scientific culture”? How does it relate to science communication, non-formal education or artistic interactions with the scientific world? That was the topic of the 14th International Summer School of Mind, Brain and Education (ISMBE), held 1–4 October 2019 at the Ettore Majorana Centre for Scientific Culture in Erice (Sicily), Italy. The ISMBE has a long history of bringing together researchers from diverse fields to catalyze research relating to cognitive science and neuroscience through to education, and the directors of the School, Drs. Kurt Fischer, Antonio Battro and Sebastián Lipina considered that the boundary between these fields and scientific culture was subtle enough to demand a conference on the subject and asked us to organize such a meeting.

Lo scienziato e l’artista

Il saggio che proponiamo prende avvio da alcune esperienze autobiografiche, contenute nel romanzo americano postmoderno. Quella di Holden Caulfield e quella di Henry Chinasky, alter ego di Charles Bukowski in Panino al prosciutto. Entrambi i romanzi sembrano quasi una forma larvata di autobiografia, dove i protagonisti dipingono una sorta di ‘ritratto dell’artista da giovane’. Tanto Holden, quanto Henry, sembrano, infatti, rappresentare la metafora o, meglio, l’archetipo dell’artista. Alla maniera di Jakov ed Holden, anche sulla scomparsa dello scienziato catanese Ettore Majorana, sembrerebbe allungarsi l’ombra di Ulisse e dell’Ebreo Errante Assuero. In essa i confini tra il reale e l’immaginario, rimarrebbero evanescenti, indeterminati come l’esistenza delle particelle quantistiche. Il mistero della scomparsa andrebbe pertanto ricercato nella realtà paradossale del mito e degli archetipi, piuttosto che in quella lineare e razionale della storia. A sintetizzare la figura dell’artista e quella dello scienziato è - in una straordinaria autobiografia - Edgar Morin.
