Unknown to one another, four unrelated sets of twins are born, and are later brought together by way of eight mysterious invitations. They quickly find themselves paired up with a stranger among themselves and must conquer a labyrinth unlike any other--or have it conquer them. Before it is all over, they will find that they have far more in common with one another than just merely being twins.

Twins are probably by no means unknown to most people - for instance in the sporting world of my Australian homeland there are quite a number of cases of note - yet very few people understand the biology behind twins. Although this book suffers a good deal from its age - people like Tim Flannery, Tom McMahon, John Rushton, and Michael Laker clearly give evidence that there is something much more "designed" than randomness involved in dizygotic twin frequencies around the world - if you want a basic introduction to the facts about twinning in humans you will get it here without any doubt. Bulmer deals with every aspects of twinning from the frequency of twinning in humans to the liabilities mothers of twins face vis-à-vis those of single children. He also goes into less common detail about the extreme difficulties of higher order multiple births - and provides little-known but easily understandable details about their frequency. Bulmer shows that for most of human history mothers of twins were at huge disadvantages both in terms of their much greater health risks and the low birth mass and short gestation of their children. For this reason, Bulmer shows that only when major health improvements were made could twins compete with singleton children, and he shows this had and has major consequences culturally. Another very interesting sidelight is Bulmer's look at how single birthing evolved as the most productive strategy in humans and other primates (except for the primitive tree shrews). Bulmer compares this with the situation in animals that typically give birth to multiple young. He should, however, have looked at the environmental conditions that encourage singleton births and compare with those animals that give birth to multiple, highly precocial offspring. All in all, though it is certainly dated, "Biology of Twinning in Man" is a simple and useful overview of what most people should know about multiple births in humans.

Many Europeans think that town twinning has greatly contributed to integration in Europe after the Second World War. This book, based on observations and interviews with twinning practitioners in small towns, reveals the social and cultural processes that inform twinning as a transnational practice, its perspectives and its limits.

The first year's work on this program is reported. It is concluded that there is good evidence for brittle fracture induced by mechanical twinning in single crystals and polycrystalline Mo-C with grain sizes larger than 0.40 mm. However there is no evidence for such failures in Mo-C of grain size smaller than 0.25 mm, or in high-purity Cb. The effect of recrystallization texture on twinning is demonstrated, and the orientation dependence of twinning in Cb crystals is reported; a most unusual plastic instability is described in crystals of one orientation. It is shown that twinning in Mo-35Re occurs in bursts, which form in less than 2 mu sec; nucleation of twins occurs only at small strains but lateral growth takes place up to at least 12% strain.

This monograph is not confined to mechanical twinning in the narrow sense (lattice reorientation in re sponse to mechanical stress); it deals also with many effects related to mechanical twinning. such as formation of reoriented regions in response to high temperatures (martensite transformations. recrystallization twins). elec tric fields (ferroelectric domains). and magnetiC fields (magnetic domains). Mechanical reorientation is discussed for classical twinning and also for an inhomogeneous distribution of residual stresses (irrational twinning. kinking. and so on). Mechanical twinning in the narrow sense (regular. symmetrical lattice reorientation in response to me chanical stress) was for many years a specialist topic for mineralogists. petrographers. and crystallographers. Mineralogists and crystallographers carried out the study of the basic geometrical relationships in twinning; the principal names here are MUgge, Niggli. Johnsen. Reusch. Baumhauer. Churchman. Wallerant. Evans. and FriedeL The laws of mechanical twinning are now widely used in mineral identification and in elucidating the conditions of formation of rocks from the minerals they contain. The distribution of the twin bands in rock forming minerals enables one to establish the later processes that have occurred in the rock. Mechanical twinning is discussed by geOlogiSts and petrologists in the analYSis of flow effects. The importance of mechanical twinning in the plastic deformation and rupture of crystalline solids was W stressed by Academician V.I. Vernadskii in 1897 and by Kirpicheva ina paper entitled WFatigue in Metals in 1914.

Tom is a smart, talented loner with a chip on his shoulder and a big secret: an imaginary twin on another planet. Eddie is Tom's opposite, a friendly, athletic kid who always looks on the good side. Tom worries sometimes: does confiding in Eddie mean he's nuts? The truth is even crazier than that. Eddie and his planet are just as real as Tom and his Earth, but fifty-some years in the past. And the twins are caught up in an alien master plan that might just mean Earth—both Earths—will be destroyed. Switching places and identities, "slipping" between planets and across decades, a desperate escape, and the unraveling of deeper secrets leave Tom and Eddie aware of the danger they're facing and the tools they can use to overcome it.
