Etat : Fair. NO TIME LIKE THE PRESENT Humanity has finally made it to the stars. Colony worlds thrive and there is general peace among the settled systems. Until now. Matte black ships of an advanced design appear in colonial systems. Their drives and weapons are not extremely advanced beyond their Terran counterparts?just superior enough to be utterly devastating. Colonies and their populations are obliterated. Once-settled worlds are rendered radioactive wastelands. Earth herself lies defenseless before the marauding enemy. DEFEND THE SKIES OF EARTH Standing against the invasion are two of humanity?s finest starship captains: Winslow Price of the British Space Navy and Anika Ahuja of the Indian Space Forces. Compatriots. Fierce competitors. Former lovers. Now they are on a quest that will plumb the scientific wells of existence, where the primordial knot of spacetime may be unraveling. Price and Ahuja are sworn to do whatever it takes to defend Earth and humanity from ultimate obliteration by an enemy that will not even speak its name. Even if it pushes each to the brink of life and death in battle. Even if it leads each beyond space and time?and to the edge of ultimate possibility! TAKE THE BATTLE TO THE STARS ?Johnson, a NASA physicist, brings verisimilitude and scientific accuracy to this adventure, and his passion for the details of space travel will undoubtedly please readers looking for old-school hard science fiction.?  ?Publishers Weekly About Mission to Methone: ?The spirit of Arthur C.

Paperback. Etat : Very Good. Two scientists give an enthusiastic, layperson's overview of a new supermaterial now in development that could transform many features of daily life, from creating new conveniences to improving health and safety.What if you discovered an infinitesimally thin material capable of conducting electricity, able to suspend millions of times its own weight, and yet porous enough to filter the murkiest water? And what if this incredible substance is created from the same element that fills the common pencil? That's graphene--a flat, two-dimensional, carbon-based molecule with a single sheet measuring only one atom thick.In this layperson's introduction to this revolutionary substance, a physicist and a chemist explain how graphene was developed, discuss the problems in scaling up production for large-scale commercial use, and forecast the potentially transformative effects of incorporating graphene into everyday life. Recent research developments include adding graphene to Silly Putty to make extremely sensitive and malleable medical sensors and compressing and fusing flakes of graphene to create a three-dimensional material that's ten times stronger than steel.This widely adaptable substance promises to change the way we interact with smartphones, laptops, information storage, and even condoms. It may also enable significant improvements to air purification, water filtration technologies, and drug delivery. This entertaining and widely accessible book offers a fascinating look into one of the most exciting developments in materials science in recent decades.…
