Solar Eclipse Results and the Principle of Relativity

The Principle of Relativity: From Ungar’s Gyrolanguage for Physics to Weaving Computation in Mathematics

‎This paper extends the scope of algebraic computation based on a non standard $times$ to ‎the more basic case of a non standard $+$‎, ‎where standard means associative ‎and commutative‎. ‎Two physically meaningful examples of a non standard $+$ are ‎provided by the observation of motion in Special Relativity‎, ‎from either ‎outside (3D) or inside (2D or more)‎, ‎We revisit the ``gyro''-theory ...

Intelligent escalation and the principle of relativity

Escalation is the fact that in a game (for instance in an auction), the agents play forever. The 0, 1-game is an extremely simple infinite game with intelligent agents in which escalation arises. At the light of research on cognitive psychology, it shows the difference between intelligence (algorithmic mind) and rationality (algorithmic and reflective mind) in decision processes. It also shows ...

Solar radiation during a total solar eclipse

Solar eclipse-burn of macula.

THE following case is of interest in view of its association with the recent partial eclipse of the sun. 2695379, Guardsman W.S.S., 1st Btn. Scots Guards, aged 27 years, came to see me on July 12, 1945, complaining of obscured vision in the left eye. ;History.-No family history. Five years ago he was in Mersa Matruh for a year. During this time he was working in an outdoor-cookhouse. ToWards th...
