Astronomical Distances
The Act of Measurement I: Astronomical Distances B. F. Riley The act of measurement causes astronomical distances to adopt discrete values. When measured, the distance to the object corresponds through an inverse 5/2 power law – the Quantum/Classical connection – to a sub-Planckian mass scale on a level or sub-level of one or both of two geometric sequences, of common ratio 1/π and 1/e, that descend from the Planck mass and may derive from the geometry of a higher-dimensional spacetime. The distances themselves lie on the levels and sub-levels of two sequences, of common ratio π and e, that ascend from the Planck length. Analyses have been performed of stellar distances, the semi-major axes of the planets and planetary satellites of the Solar System and the distances measured to quasars, galaxies and gamma-ray bursts. 1 Introduction Using Planck units the Quantum/Classical connection, characterised by the equation (1) maps astronomical distances R – in previous papers only the radii of astronomical bodies [1, 2] – onto sub-Planckian mass scales m on the mass levels and sub-levels1 of two geometric sequences that descend from the Planck mass: Sequence 1 of common ratio 1/π and Sequence 3 of common ratio 1/e.2 The sequences may derive from the geometry of a higher-dimensional spacetime [3]. First, we show that several distances associated with the Alpha Centauri system correspond through (1) to the mass scales of principal levels3 in Sequences 1 and 3. We then show that the mass scales corresponding through (1) to the distances from both Alpha Centauri and the Sun to the other stars lie on the levels and sub-levels of Sequences 1 and 3. -

Glossary of Terms Absorption Line a Dark Line at a Particular Wavelength Superimposed Upon a Bright, Continuous Spectrum
Glossary of terms absorption line A dark line at a particular wavelength superimposed upon a bright, continuous spectrum. Such a spectral line can be formed when electromag- netic radiation, while travelling on its way to an observer, meets a substance; if that substance can absorb energy at that particular wavelength then the observer sees an absorption line. Compare with emission line. accretion disk A disk of gas or dust orbiting a massive object such as a star, a stellar-mass black hole or an active galactic nucleus. An accretion disk plays an important role in the formation of a planetary system around a young star. An accretion disk around a supermassive black hole is thought to be the key mecha- nism powering an active galactic nucleus. active galactic nucleus (agn) A compact region at the center of a galaxy that emits vast amounts of electromagnetic radiation and fast-moving jets of particles; an agn can outshine the rest of the galaxy despite being hardly larger in volume than the Solar System. Various classes of agn exist, including quasars and Seyfert galaxies, but in each case the energy is believed to be generated as matter accretes onto a supermassive black hole. adaptive optics A technique used by large ground-based optical telescopes to remove the blurring affects caused by Earth’s atmosphere. Light from a guide star is used as a calibration source; a complicated system of software and hardware then deforms a small mirror to correct for atmospheric distortions. The mirror shape changes more quickly than the atmosphere itself fluctuates. -

EBL with GRB and Blazars Joel Primack with Rudy Gilmore, Alberto Dominguez, & Rachel Somerville
EBL with GRB and Blazars Joel Primack with Rudy Gilmore, Alberto Dominguez, & Rachel Somerville Thursday, March 25, 2010 The EBL is very difficult to observe directly because of foregrounds, especially the zodiacal light. Reliable lower limits are obtained by integrating the light from observed galaxies. The best upper limits come from (non-) attenuation of gamma rays from distant blazars, but these are uncertain because of the unknown emitted spectrum of these blazars. This talk concerns both the optical-IR EBL relevant to attenuation of TeV gamma rays, and also the UV EBL relevant to attenuation of gamma rays from very distant sources observed by Fermi and low-threshold ground- based ACTs. log dNγ/dE Just as IR light penetrates dust better than shorter wavelengths, so lower energy gamma rays penetrate the EBL better than higher energy, resulting in a softer observed gamma- ray spectrum from more distant sources. log E Thursday, March 25, 2010 PILLAR OF STAR BIRTH Carina Nebula in UV Visible Light Thursday, March 25, 2010 PILLAR OF STAR BIRTH Carina Nebula in IR Light Longer wavelength light penetrates the dust better Longer wavelength gamma rays also penetrate the EBL better Thursday, March 25, 2010 Gamma Ray Attenuation due to γγ e+e- If we know the intrinsic spectrum, we can infer the optical depth (E,z) from the observed spectrum. In -Γ practice, we assume that dN/dE|int is not harder than E with Γ = 1.5, since local sources have Γ ≥ 2.

“How is it possible that mathematics, a product of human thought that is independent of experience, fits so excellently the objects of physical reality?” “¿Cómo es posible que la matemática, un producto del pensamiento humano independiente de la experiencia, se adapte tan admirablemente a los objetos de la realidad?”1 Albert Einstein (1879-1955) “Intelligent people would never say, ‘I don’t care about art, or music. But it is totally okay to say, ‘I hate math.’” The Great Math Mystery Mario Livio (1950 - ) Astrophysicist and writer Astrofísico y escritor Astrophysicien et écrivain Space Telescope Science Institute LIVIO, Mario, “The Great Math Mystery”.

The Great Math Mystery Documentary New 2015 HD http://docuwiki.net/index.php?title=T... The Great Math Mystery Documentary New 2015 HD NOVA leads viewers on a mathematical mystery tour –a provocative exploration of math’s astonishing power across the centuries. We discover math’s signature in the swirl of a nautilus shell, the whirlpool of a galaxy, and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the successful landing of rovers on Mars. But where does math get its power? Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists, and engineers, follow math from Pythagoras to Einstein and beyond, all leading to the ultimate riddle: Is math an invention or a discovery? Humankind’s clever trick or the language of the universe? Whether we think we’re good with numbers or not, we all use math in our daily lives.
