World view: Missing weapons

Overall View of Chemical and Biochemical Weapons

This article describes a brief history of chemical warfare, which culminated in the signing of the Chemical Weapons Convention. It describes the current level of chemical weapons and the risk of using them. Furthermore, some traditional technology for the development of chemical weapons, such as increasing toxicity, methods of overcoming chemical protection, research on natural toxins or the in...

Nuclear Weapons and the Second World War

Since the obliteration of Hiroshima and Nagasaki, nuclear weapons have captured the attention of social scientists and the public alike. Some argue that the world benefits from nuclear weapons, claiming that they prevent war. Skeptics do not share this view and worry that nuclear weapons will only intensify conflict. Unfortunately, most theories about the benefits of nuclear weapons await judge...

Linear Multi View Reconstruction with Missing Data

General multi view reconstruction from affine or projective cameras has so far been solved most efficiently using methods of factorizing image data matrices into camera and scene parameters. This can be done directly for affine cameras [18] and after computing epipolar geometry for projective cameras [17]. A notorious problem has been the fact that these factorization methods require all points...

Object Motion: A World View

Moving objects are detected by virtue of their shifting image on the retina. But to know how objects are moving in the world, we must take into account the rotation of our eyes, as well as the rotation of our head. A recent paper describes neurons that carry out this computation.
