Cohl Furey – summary – links between the Standard Model of particle physics and the octonions

In mathematics, the octonions are a normed division algebra over the real numbers, usually represented by the capital letter O, using boldface O or blackboard bold {\displaystyle \mathbb {O} } \mathbb {O} . Octonions have eight dimensions; twice the number of dimensions of the quaternions, of which they are an extension. They are noncommutative and nonassociative, but satisfy a weaker form of associativity; namely, they are alternative.

Octonions are not as well known as the quaternions and complex numbers, which are much more widely studied and used. Despite this, they have some interesting properties and are related to a number of exceptional structures in mathematics, among them the exceptional Lie groups. Additionally, octonions have applications in fields such as string theory, special relativity, and quantum logic. [ wikipedia ]

Carlo Rovelli – “Space is blue and birds fly through it”

by Carlo Rovelli – “Quantum mechanics is not about ‘quantum states’: it is about values of physical variables. I give a short fresh presentation and update on the relational perspective on the theory, and a comment on its philosophical implications.” (Submitted on 8 Dec 2017 (v1), last revised 29 Jan 2018 (this version, v5))

Israeli Practices towards the Palestinian People

Israeli Practices towards the Palestinian People and the Question of Apartheid – Palestine and the Israeli Occupation , Issue No. 1 United Nations Beirut, 2017

 

Rima Khalaf, the head of the Economic and Social Commission for Western Asia (ESCWA) which published the report, announced her resignation at a press conference in Beirut on Friday.
Reuters reports that Khalaf took the step “after what she described as pressure from the secretary-general to withdraw a report accusing Israel of imposing an ‘apartheid regime’ on Palestinians.”
“I resigned because it is my duty not to conceal a clear crime, and I stand by all the conclusions of the report,” Khalaf stated.    |    see also
