Book Description
Twins present special problems for the study of lateralisation, both psychological and biological. Central to both areas is the common observation that identical (monozygotic) twins can differ in their laterality. In the case of hand preference, this is most obvious in the one in five twin pairs where one is right-handed and the other left-handed. A similar problem can be found morphologically, not only in normal anatomical traits, such as hair whorls, which can be in opposite direction, but also in the rare condition of conjoined twins, where it is frequently the case that one twin has its heart and viscera in the normal orientation (situs solitus) and the other is mirror reversed (situs inversus). This special issue of Laterality brings together papers on these different aspects of twinning. Two of the papers are biological, one providing a detailed analysis of the laterality of artificially conjoined twins created by fusing two different species of newt, and the other overviewing the recent developments in understanding the molecular biology of visceral lateralisation in relation to twinning. The other papers concern aspects of cerebral lateralisation in twins, one providing a much needed meta-analysis and critical overview of the twin literature, another providing detailed data from a large study of handedness in twins, a third asking about the almost neglected question of footedness, earedness and eyedness in twins, and the fourth looking at lateralised cognitive processing. Between them these papers extend the literature on lateralisation in twins, and reinforce the need to consider the lateralisation of twins from biological, neurological and psychological perspectives.

Book Description
In two of my previous published books, “Two hundred conjectures and one hundred and fifty open problems on Fermat pseudoprimes”, respectively “Conjectures on primes and Fermat pseudoprimes, many based on Smarandache function”, I already expressed my passion for integer numbers, especially for primes and Fermat pseudoprimes, fascinating numbers that seem to be a little bit more willing to let themselves ordered and understood than the prime numbers.

Book Description
A NEW YORK TIMES NOTABLE BOOK The Babylonians invented it, the Greeks banned it, the Hindus worshipped it, and the Christian Church used it to fend off heretics. Today it's a timebomb ticking in the heart of astrophysics. For zero, infinity's twin, is not like other numbers. It is both nothing and everything. Zero has pitted East against West and faith against reason, and its intransigence persists in the dark core of a black hole and the brilliant flash of the Big Bang. Today, zero lies at the heart of one of the biggest scientific controversies of all time: the quest for a theory of everything. Within the concept of zero lies a philosophical and scientific history of humanity. Charles Seife's elegant and witty account takes us from Aristotle to superstring theory by way of Egyptian geometry, Kabbalism, Einstein, the Chandrasekhar limit and Stephen Hawking. Covering centuries of thought, it is a concise tour of a world of ideas, bound up in the simple notion of nothing.

Book Description
Centered around the 2011 Libyan Revolution, Libyan Sugar is a road trip through a war zone, detailed through photographs, journal entries, and written communication with family and colleagues. A record of Michael Christopher Brown's life both inside and outside Libya during that year, the work is about a young man going to war for the first time and his experience of that age-old desire to get as close as possible to a conflict in order to discover something about war and something about himself, perhaps a certain definition of life and death.

Book Description
The Theory of Prime Number Classification This is an expository work of mathematical research into the prime numbers based on pattern methodology and classification techniques. As a comprehensive research into the classification systems for prime numbers, it address the following: „X Why prime numbers are regular yet random. „X What are the building blocks of prime numbers „X What is the framework for prime number generation This is done by developing the following classification systems: „X The Prime Root Classification. All prime numbers are constituted by roots, which are defined as the building blocks of the prime number. „X The Positional Classification. A two dimensional prime number space is defined that allows certain types of distribution analysis of primes to be made, deriving count functions and establishing the mean property of primes „X The Delta Classification of Primes. This classification creates prime families in terms of gaps. Prime gaps are found to have positive, negative and a steady gap acceleration. „X The Gap Theory Classification. All prime gaps and prime number behavior are based on Gap 2, Gap 4 and Gap 6. This then develops a classification system. Using the above classification systems, and defining a special function, a theory of prime number generation is then suggested, where this leads to the development of an algebraic sieve for finding prime numbers. The algebraic sieve contains all the relevant information about prime numbers, including how gaps widen, and prime number patterns. Consequently, it is then used to address the problem of finding a proof for the twin prime conjecture. As an expository work, the book also shares personal experiences and thoughts with regard to the research, and the development of expository mathematics. A program for prime number classification is available at www.zwideprimes.com
