Some time ago a rather large US entertainment company bought a few licenses for my HTML5 Game Engine Impact. They used it for internal prototyping and, as they told me, were quite happy with it. A few month later I got an email from the company's legal department. They asked me to sign an amendment to the Impact Software license agreement with three additional terms. I assume they wanted to publish a game they made with Impact.

Personne ne sera surpris d’apprendre que la science-fiction a la cote auprès des adolescents. Pourquoi n’était-elle donc pas plus utilisée en classe pour motiver les jeunes élèves à l’enseignement des sciences – ou même (re)dorer le blason du scientifique, s’est questionnée une équipe de chercheurs espagnols.

Introduced by the two renowned theoretical physicists Stephen Hawking and Leonard Mlodinov in their book The Grand Design in 2010, model-dependent realism is a new controversial understanding of the universe. Based on solid logical reasonings and recent development in physics, this concept may well be an incredible breakthrough for philosophy and science, as well as metaphysics.
