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

|Please join us in celebrating the fifth birthday of His Holiness Drubwang Pema Norbu’s Yangsi, Migyur Dechen Garwang Zilnon Dorje, on January 7. On this joyous occasion, we will hold a Grand Rigdzin Dupa Tsok Offering and prayers for His Holiness’ long life, followed by a dinner party in the evening featuring traditional food, performances, a DJ and dancing!
To help fulfill His Holiness’ aspiration of establishing a Palyul Dharma Center in New York City, the donation for the dinner party in the evening will be $35 per person, which will go towards the purchase of a new space for the Center. Thanks to everyone’s kind and dedicated support, we are much closer to reaching this goal – please come and join this effort so we may soon bring His Holiness’ vision to life.
These three lines in the Standard Model are ultraspecific to the gluon, the boson that carries the strong force. Gluons come in eight types, interact among themselves and have what’s called a color charge.
Almost half of this equation is dedicated to explaining interactions between bosons, particularly W and Z bosons.
Bosons are force-carrying particles, and there are four species of bosons that interact with other particles using three fundamental forces. Photons carry electromagnetism, gluons carry the strong force and W and Z bosons carry the weak force. The most recently discovered boson, the Higgs boson, is a bit different; its interactions appear in the next part of the equation.
This part of the equation describes how elementary matter particles interact with the weak force. According to this formulation, matter particles come in three generations, each with different masses. The weak force helps massive matter particles decay into less massive matter particles.
This section also includes basic interactions with the Higgs field, from which some elementary particles receive their mass.
Intriguingly, this part of the equation makes an assumption that contradicts discoveries made by physicists in recent years. It incorrectly assumes that particles called neutrinos have no mass.
In quantum mechanics, there is no single path or trajectory a particle can take, which means that sometimes redundancies appear in this type of mathematical formulation. To clean up these redundancies, theorists use virtual particles they call ghosts.
This part of the equation describes how matter particles interact with Higgs ghosts, virtual artifacts from the Higgs field.
This last part of the equation includes more ghosts. These ones are called Faddeev-Popov ghosts, and they cancel out redundancies that occur in interactions through the weak force.
Thomas Gutierrez, an assistant professor of Physics at California Polytechnic State University, transcribed the Standard Model Lagrangian for the web. He derived it from Diagrammatica, a theoretical physics reference written by Nobel Laureate Martinus Veltman. In Gutierrez’s dissemination of the transcript, he noted a sign error he made somewhere in the equation.

One of the oldest [ca. 75-125 A.D] and most complete diagrams from Euclid’s Elements of Geometry is a fragment of papyrus found among the remarkable rubbish piles of Oxyrhynchus in 1896-97 by the renowned expedition of B. P. Grenfell and A. S. Hunt. It is now located at the University of Pennsylvania. The diagram accompanies Proposition 5 of Book II of the Elements, and along with other results in Book II it can be interpreted in modern terms as a geometric formulation of an algebraic identity – in this case, that ab + (a-b)2/4 = (a+b)2/4
“If a straight line be cut into equal and unequal segments, the rectangle contained by the unequal segments of the whole together with the square on the straight line between the points of section is equal to the square on the half.” (from the classic translation of T. L. Heath)
