Eliyahu Rips

Eliyahu Rips is an Israeli mathematician of Latvian origin known for his research in geometric group theory. He became known to the general public following his coauthoring a paper on what is popularly known as Bible code, the supposed coded messaging in the Hebrew text of the Torah. Ilya Rips grew up in Latvia, his mother was Jewish and from the only of nine siblings that survived the war. His father Aaron was a Jewish mathematician from Belarus. Rips was the first high school student from Latvia to participate in the International Mathematical Olympiad. In January 1969 he learnt from listening to Western radio broadcast---then illegal in the USSR---of the self-immolation of Czechoslovak student Jan Palach. On 13 April 1969, Rips a graduate student at the University of Latvia, attempted self-immolation in a protest against the Soviet invasion of Czechoslovakia. After unwrapping a self-made slogan condemning the occupation of Czechoslovakia he lit a candle and set his gasoline-soaked cloths ablaze.

A group of bystanders were able to put the fire out, resulting only in burns to Rips' neck and hands. Though injured, he was first interrogated, he was incarcerated by the Soviet government for two years. After his story spread among Western mathematical circles and a wave of petitions, Rips was freed in 1971; the following year, he was allowed to immigrate to Israel. Rips joined the Department of Mathematics at the Hebrew University of Jerusalem, in 1975 completed his Ph. D. in mathematics there. His topic was the dimensional subgroup problem, he was awarded the Aharon Karzir Prize. In 1979, Rips received the Erdős Prize from the Israel Mathematical Society, was a sectional speaker at the International Congress of Mathematicians in 1994. Rips is a professor in the Department of Mathematics at Hebrew University, his research interests are combinatorial methods in infinite group theory. This includes small cancellation theory and its generalizations, hyperbolic group theory, Bass-Serre theory and the actions of groups on R -trees.

Rips' work on group actions on R -trees is unpublished. The Rips machine, in the hands of Rips and his student Zlil Sela, has proven to be effective in obtaining classification results such as a solution to the isomorphism problem for hyperbolic groups. In the late 1970s, Rips began looking with the help of a computer for codes in the Torah. In 1994, together with Doron Witztum and Yoav Rosenberg, published in the journal Statistical Science an article, "Equidistant Letter Sequences in the Book of Genesis", which claimed the discovery of encoded messages in the Hebrew text of the Book of Genesis. This, in turn, was the inspiration for the 1997 book The Bible Code by journalist Michael Drosnin. While Rips claimed that he agreed with Drosnin's findings, in 1997 Rips described Drosnin's book as "on shaky ground" and "of no value." Since Drosnin's book, Bible codes have been a subject of controversy, with the claims being criticized by Brendan McKay and others. An early supporter of Rips' theories was Robert Aumann, Nobel Prize Laureate in Economics 2005, who headed a commission overseeing Rips' experiments attempting to prove the existence of a secret code from God in the Torah.

Aumann abandoned the idea and withdrew his support from Rips. The Bible Code treats the text of the Bible as a word search puzzle: for example, a word may be spelled diagonally moving in a north west direction, or left-to-right taking every second letter; the more patterns that are allowed, the more words that can be found. Elementary statistics can be used to estimate the probabilities of finding certain hidden messages; the statistician Jeffrey S. Rosenthal shows in his book Struck by Lightning: The Curious World of Probabilities that "hidden messages" are statistically expected and hence should not be seen as divine messages, much less as predictions of the future. Mathematician Brendan McKay illustrated this point by finding messages in the English text of Moby Dick that "predicted" famous assassinations of the past, such as the assassination of John F. Kennedy and the assassination of Indira Gandhi; the 1997 "Ig Nobel Prize for Literature" was awarded to Eliyahu Rips, Doron Witztum, Yoav Rosenberg, Michael Drosnin, for their work on Bible codes.

Masenqo

The masenqo or chira-wata is a single-stringed bowed lute found in the musical traditions of Ethiopia and Eritrea. As with the krar, this instrument is used by Ethiopian minstrels called azmaris. Although it functions in a purely accompaniment capacity in songs, the masenqo requires considerable virtuosity, as azmaris accompany themselves while singing; the square- or diamond-shaped resonator is made of four small wooden boards glued together covered with a stretched parchment or rawhide. The single string is made of horse hair, passes over a bridge; the instrument is tuned by means of a large tuning. It may be bowed by either the right or left hand, the non-bow hand sits on top of the upper part of the string. Music of Ethiopia Music of Eritrea

.375 Weatherby Magnum

The.375 Weatherby Magnum is a medium-bore rifle cartridge. The cartridge is a blown out and provided with the Weatherby double radius shoulder – given the Weatherby treatment – version of the.375 H&H Magnum. Unlike other improved versions of the.375 H&H Magnum like the.375 Ackley Improved, the.375 Weatherby Magnum is not a wildcat and existed as a proprietary cartridge until the CIP published specifications for the cartridge. The.375 Weatherby Magnum was designed by Roy Weatherby in South Gate California in 1944 and put into production in 1945. The original cases were fire formed from.300 H&H Magnum Winchester brass from Richard Speer’s 300 Weatherby brass before settling with Norma as a source for cases. It was with Norma that Weatherby found a source for loaded ammunition. Production of.375 Weatherby ammunition was reintroduced in 2001 due to demand. The.375 Weatherby was designed as a dangerous game cartridge. The cartridge is able to fire a 300 gr bullet at 2,800 ft/s generating a muzzle energy of 5,224 ft⋅lbf with the trajectory of the 30-06 Springfield.

This performance level makes it an appropriate all round African safari cartridge, usable against plains game species as well. The.375 Weatherby is considered overly powerful for North American game. As the.375 Weatherby is an improved cartridge.375 H&H Magnum ammunition can be fired in.375 Weatherby chambers with a slight loss in performance of the.375 H&H ammunition. Cases thus fired are in essence fire formed to the Weatherby cartridge's dimensions and if reloaded should be reloaded using.375 Weatherby reloading data. Reloading data is available from A-Square and Hornady. Ammunition is available from A-Square and Connelly Precision. Rifles are available from A-Square. Most.375 H&H rifles can be converted to the.375 Weatherby Magnum by having the new chamber reamed with no further modifications made to the rifle. The cartridge makes an excellent choice for those who want a step up in performance over the.375 H&H Magnum without the recoil or cost of the.378 Weatherby Magnum. The.375 Weatherby Magnum is an improved version of the.375 H&H Magnum.

The parent case necked up to accept a. 375 in. The cartridge features the Weatherby double radius shoulder; the Weatherby Magnum is not considered a proprietary cartridge as the CIP has published specifications for the cartridge. CIP recommends a 6 groove barrel with groove width of 3.25 mm, a bore Ø of 9.35 mm and a groove Ø of 9.55 mm. The recommended twist rate is one revolution in 305 mm. Case capacity is 105 gr. of water. The FreeBore/Leade for this Cartridge is 0.373 thou. as per the Factory Spec's. As an improved cartridge the.375 Weatherby Magnum provides a leap in performance over its parent cartridge. The velocity gain over the.375 H&H Magnum works out to be about 240 ft/s and an increase in maximum point blank range of about 25 yd with bullets of equal weight. The.375 Weatherby Magnum fires a 270 gr at 2,940 ft/s generating 5,181 ft⋅lbf and a 300 gr at 2,800 ft/s which generates 5,224 ft⋅lbf. The cartridge generates more energy than factory loads for the.375 Remington Ultra Magnum.416 Rigby or the.458 Winchester Magnum.

Andreas Winter

Andreas Winter is a German mathematician and mathematical physicist at the Universitat Autònoma de Barcelona in Spain. He received his Ph. D. in 1999 under Rudolf Ahlswede and Friedrich Götze at the Universität Bielefeld in Germany before moving to the University of Bristol and to the Centre for Quantum Technologies at the National University of Singapore. In 2013 he was appointed ICREA Research Professor at UAB. Winter's research is focused in the field of quantum information theory; some of his main contributions concern the understanding of quantum communication protocols, the coding theory for quantum channels, the theory of quantum entanglement. Together with Michał Horodecki and Jonathan Oppenheim, he discovered quantum state-merging and used this primitive to show that quantum information could be negative. Together with Marcin Pawlowski, Tomasz Paterek, Dagomir Kaszlikowski, Valerio Scarani, he discovered information causality. Together with Runyao Duan and Simone Severini, he introduced a quantum mechanical version of the Lovász number.

Together with Sandu Popescu, Noah Linden and Tony Short he proved that local equilibration of large quantum systems is a generic phenomena. He was awarded the Philip Leverhulme Prize for Mathematics and Statistics in 2008 and in 2012 the Whitehead Prize of the London Mathematical Society.
