In September 2005, Yerevan (Armenia) hosted an International Conference dedicated to the 70th anniversary of the publication of the so called "green paper," published by N.W. Timofeeff-Ressovsky, K.

The importance of this paper for genetics and radiobiology was enormous not only for radiobiology, but for genetics in general. The "target" of the radiation action was indeed the "gene," that for the first time found a clear, operational definition. The organisers of this Conference proposed to...

Nobel Laureate Eugene Wigner once wondered about "the unreasonable effectiveness of mathematics" in the formulation of the laws of nature. Is God a Mathematician? investigates why mathematics is as powerful as it is. From ancient times to the present, scientists and philosophers have marveled at how such a seemingly abstract discipline could so...

In the fifteenth century, a Venetian mariner, Michael of Rhodes, wrote and illustrated a text describing his experiences in the Venetian merchant and military fleets. He included a treatise on commercial mathematics and treatments of contemporary shipbuilding practices, navigation, calendrical systems, and astrological ideas. This manuscript, "lost," or at least in unknown hands for over 400 years, has never been published or translated in its entirety until now. In volume 3, nine experts, including the editors, discuss the manuscript, its historical context, and its scholarly importance....
