My relativity article is at: relativitytrail.com/preprint.special_relativity.pdf 03/09/2024 note: In February 2024, during the process of researching a definition for use in my article, I stumbled upon an obscure lecture delivered by Einstein at Leyden in 1920. I learned, by way of reading the transcript of that lecture, that Einstein had by that time (fifteen years after his 1905 paper on relativity) come around to the correct way of thinking about the nature of space as it relates to special relativity. Specifically, he forcefully argued that there is necessarily an underlying frame of reference for the effects of special relativity, i.e., a background which needs to be appealed to in order for there to be standards for distance, clocks and rods. That is in sharp contrast to his original treatment. Having spent my entire adult life searching the literature for anyone other than myself who has understood and articulated why that background (call it aether or the totality of the cosmos) is not merely an option when it comes to explaining the effects of relativity, it seems safe to say that thus far only Einstein himself rose to the task. He partially rose to the task. He never did go back and rework special relativity in absolute terms with new postulates. (I did that in 2008. It's my book Relativity Trail, which I sell at the U of M.) You can read what Einstein said in my article. Take the challenge and enrich yourself if you think you're brave enough. It's a short read: relativitytrail.com/preprint.special_relativity.pdf
Mini-journal: June 11 2023 Time flies. Been one year since I had the honor of playing host for one month to Scott Booth -- talented folk songwriter and singer. Four albums to date. Played lots of catch with the baseball and rode bikes. Also had the honor of creating Scott's official website for his music. Listen to my favorites at his website: scotman.net ----------------------------- archives old and recent -----------------------------

Relativity in absolute terms There are only three sane sections in the Wikipedia article on the twin paradox of special relativity. I authored those sections in 2011, and they've been there continuously since that time: Here's the link to the three sections below. 4. A non space-time approach 5. The equivalence of biological aging and clock time-keeping 12. No twin paradox in an absolute frame of reference
On several fundamental levels, Relativity Trail eclipses the works of Poincare, Lorentz and Einstein regarding the underpinnings and kinematics of special relativity: link: The originality and uniqueness of Relativity Trail
The twin paradox of special relativity cannot be resolved without acknowledging a hierarchy of clock rates dependent on a hierarchy of inertial motion. © 2022 relativitytrail.com Relativity Trail explains the time differential between reunited clocks, eliminates the twin paradox, diagrams Einstein's clock sychronization in absolute terms, and ends all confusion regarding relative frames of reference. It's completely compatible with, and in fact subsumes, Einstein's relativity. It reveals what is transpiring behind the scenes of Einstein's treatment. Spacetime is shown to be dependent on Einstein's clock synchronization method, and is properly relegated to a geometrical construct which comes up short as a physical reality. © 2008 relativitytrail.com Relativity Trail, with 192 pages, 65 diagrams and 75 illustrations, will provide you with complete detailed algebraic derivations of all the kinematical effects of special relativity. Everything is charted out in absolute terms against a system at rest with respect to the totality of the universe for perfect clarity as well as soundness of theoretical basis. It is the totality of the universe that imparts the inertial properties of clock rates and lengths which generate the effects of relativity. This is explained in detail in Relativity Trail Introductory document: Relativity in absolute terms (can be read with comprehension in twelve minutes) Absolute versions of Einstein's postulates (a snippet from the above document -- can be read with comprehension in three minutes) Twin Paradox Animation on youtube. Light rays and traveling twins are charted in absolute terms, free of the misleading space-time diagram. I wrote the program code for the animation using QuickBASIC for DOS.
