Attack Vector Tactical 3E, by Ad Astra Games, is the third edition of one of the most realistically modeled tabletop 3D space combat wargame, where warships dance the ballets of death while slinging kinetics and feeling crackles of laser ablating the armor, waiting for the right position and timing to counterattack.

Blaise Pascal was born on June 19, 1623. A French mathematician, physicist, inventor, philosopher, writer, and Catholic theologian. Like his contemporary René Descartes, Pascal was also a pioneer in the natural and applied sciences. Pascal wrote in defense of the scientific method and produced several controversial results. He made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalising the work of Evangelista Torricelli. In 1642, while still a teenager, he started some pioneering work on calculating machines, establishing him as one of the first two inventors of the mechanical calculator.
