LOG#209. A cosmic link with a non-trivial zeta zero?

Some weeks ago, the Riemann zeta function and the Riemann hypothesis were again in the news. Sir Michael Atiyah proposed a (wrong) failed proof of the Riemann hypothesis. My blog has an history of being controversial from time to time. … Continue reading

LOG#208. Monsters and LISA.

Black holes and other astrophysical objects are true monsters. Some interesting tools from web pages to learn about these free catalogues: WATCHDOG and BLACKCAT. Also, the blackhole.org page and the sounds of spacetime for gravitational waves are suitable for you. … Continue reading

LOG#207. Beck, Zeldovich and maximal acceleration: the vacuum.

Some time ago, Zeldovich derived the following expression for the vacuum energy density: (1)   or equivalently, with a link to Caianiello’s maximal acceleration formula, (2)   Remark: the above vacuum energy density is related to the cosmological constant via … Continue reading

LOG#206. Multitemporal theories.

Newton’s gravity reads:     In extra dimensions, , , it reads     For extra dimensions, if their size are much smaller than considered distances, , then by matching         So, gravitational is weak in our … Continue reading

LOG#205. Ether wind, SR and light clocks.

From the Michelson-Morley experiment, some clever experimentalist tried to derive the light speed through the “ether wind”. It is very similar to a river being rowing by sailors in a boat. The times for journey “upstream” and “downstream” are:   … Continue reading

LOG#204. Mechanics and light.

Gravitational or electrical forces are inverse squared laws:         Strikingly similar, they are both also conservative forces. For gravity:     and     for the electrical force. Defining the potentials , and , you get the … Continue reading

LOG#203. Action gym.

A challenge post! 😉 Quantum physics becomes important when the magnitude called action is of order of Planck constant (an action itself!). Action is quantized. It is a much more essential quantization than that of energy or angular momentum (action … Continue reading

LOG#202. Harmonic oscillator.

Some clever physicists say that everything is an harmonic oscillator, and that every hard problem is just solvable in terms of a suitable set of harmonic oscillators (even true with string theory!): In classical mechanics (CM) you have a the … Continue reading

LOG#201. Generalized absement.

Absement is generally defined as (1)   We can even integrate the absement -times (position integrated -times) to get (2)   i.e. (3)   with dimensions of and units of . However, if time is multidimensional, and the time vector … Continue reading

LOG#200. TSOR: The Spectrum Of Relativity.

Happy New Year 2018, dear followers! Today is a special blog post! My 200th post! After a really terrible 2017 from the viewpoint of family, health and productivity, I wish this one will be a great year for me and … Continue reading
