Tesla's Egg of Columbus, Radar Stealth, The Torsion Tensor, and the Philadelphia Experiment

At a glance..

In this paper, we follow the thread leading from Tesla's spinning "Egg of Columbus" demonstration, through his proposal of a large rectangular helix disposed about the hull of a ship for U-boat detection, to Arnold Sommerfield's discussion of magnetically biased ferrites creating electromagnetic stealth for WW-II submarines.

'Tesla's Egg of Columbus and Other Adventures' delves into the fascinating world of inventor Nikola Tesla. The book focuses on some lesser-known aspects of his work such as his proposal for a large rectangular helix around a ship's hull for U-boat detection during World War II. It also examines how Arnold Sommerfeld used magnetically biased ferrites to create electromagnetic stealth in submarines during that same war.

The authors calculate that magnetic fields with an order magnitude greater than 15,000 A/m would be required to reduce a ship's radar reflection at L-Band (1.5 GHz) to less than one percent - leading them to speculate about whether this level could have been achieved in experiments like the infamous Philadelphia Experiment'. They explore what effects such intense fields might have had on salt water or humans if driven at certain frequencies.

In addition to examining these topics from both classical and relativistic perspectives available before WWII, Anderson & Peat also discuss temporal bifurcations arising from ferromagnetic spin using Hehl's hypothesis regarding localized Cartan Torsion tensors. They propose two physical experiments which distinguish temporal anisotropy arising from anholonomity (the Sagnac effect) versus Eddington's

version of unified field theory.

While acknowledging their study is partly speculative due to limited knowledge surrounding these subjects, they offer specific predictions based on theoretical analyses which can be experimentally examined by third parties qualified in magnetics research.
