Microbial Model of the Expansion of the Universe According to Hubble

Authors: Vladimir Aksayskiy
Comments: 1 Page.

From the point of view of a microbiologist, the Hubble equation describes the expansion of the Universe as an exponential growth phase of a colony of microbes-galaxies on the surface of a dark nutrient medium. In the microbial model, the growth of a colony is carried out by the reproduction of galaxies by binary fission with a generation time of 5u2022109 years. The currently observed number of galaxies of the order of 1011 corresponds to 35 generations in the model.

The Physics Paradox

Authors: Clark M. Thomas
Comments: 5 Pages.

The physics paradox demands we perceive the realphysics and astrophysics outside stale paradigms.Deep problems within experimental physics aremostly dimensional and conceptual. Elegancerequires a clear view of foundational physics, whichwill lead soon to the resolution of supersymmetry.Experimental physicists may contend thatwhatever theoretical physics has not yet beenverified, or deemed verifiable, is not science. Foran elegant modern physics to emerge, science mustrealize our mutual limitations.

Draft of a Reformed Synthetic Approach to Philosophy, Cognition and Beyond

Authors: Salvatore Spadaro
Comments: 28 Pages.

A new epistemic approach is proposed. Recent trends in philosophy show thatthe analytic style is losing its verve; some reasons are: the emerging role ofprobabilistic/statistical approaches (in opposition to the logical ones) to the mindbrain(e.g. Bayesian approaches) and their central role in contemporary science, moreover theprevailing deterministic approach to the world of the analytic school, influenced by firstorder logic and classical physics, seems to be inadequate; for this reason, it will used anundeterministic modus operandi. Also psychology, intuitions and creativity will have animportant role in this approach. The starting points of this hypothetical method are HenriPoincarè’s synthetic way in philosophy (in opposition to Bertrand Russell’s analytic way)and Max Born’s indeterministic way in science (in opposition to Albert Einstein’sdeterministic way). A reform, in connection with actual trends in philosophy and science,will be applied to Poincarè’s synthetic approach.

Adaptar Impedancia en Radio con un Tramo de Cable Coaxial
Match Radio Impedance with a Length of Coaxial Cable

Mi transceptor tiene en el conector de antena una impedancia de 50 ohm. El cable coaxial que baja desde la antena es de 75 ohm. Quiero usar un tramo de coaxial de 50 ohm entre el equipo y la bajada, para adaptar impedancias. ¿ Qué longitud debo dar al tramo adaptador ? Esa pregunta motivó un ejercicio de física cualitativa, que es la parte sustancial de este documento. Colateralmente aparece una fórmula construida cualitativamente, es decir que no proviene de un desarrollo analítico ni está demostrada. Esa fórmula expone un cálculo que, con suerte, tal vez sirva para dar al tramo adaptador una longitud que lo haga útil en la práctica.

My transceiver has an impedance of 50 ohms in the antenna connector. The coaxial cable coming down from the antenna is 75 ohm. I want to use a section of 50 ohm coaxial between the equipment and the drop, to adapt impedance. How long should I give the adapter section? That question motivated an exercise in qualitative physics, which is the substantial part of this document. Collaterally, a qualitatively constructed formula appears, that is, it does not come from an analytical development nor is it demonstrated. That formula gives a calculation that hopefully will give the adapter leg a length that makes it practically useful.

Our Civilization at a Critical Historical Moment

Authors: Stoyan Sarg
Comments: 4 Pages. ecology of life

Our civilization is at a critical moment in its existence. Why is this not felt by politicians and world institutions? The reason is a serious misconception about the physics of space, which does not allow predicting one dangerous effect, which might happen in case of a nuclear war: the loss of part or the entire earth's atmosphere.
