(1) A curious pattern: — A appears when calculating the value of π to the power of a negative even number: Reminder: The above formula, π^-n , is calculated as 1/π^n. When n is zero, the value of π^-n is 1. (2) AML Isolation: — The segregation between currencies, preventing…

Given a problem to be solved, we may use a wrong procedure, or we may provide an answer to the wrong question. Neither is helpful in problem solving. But with paradoxes, we can be wrong in even more ways. When presented with the paradox of Achilles and the tortoise, some…

In the last few days the following scam using an NFT was attempted, and is described by the targeted person (thomasg.eth on twitter) here. The following lessons can be learned: 1. Some scammers are willing to invest a lot of time and create an elaborate fictitious scenario when they are…

Abstract The observable universe, as we see it through telescopes, needs to be consistently interpreted according to relativistic geometry. In an article published several years ago, I pointed out a hypothesis that describes a different view of spacetime: the Everted View. In this article I briefly explain how dark matter…
