In this imaginative volume, Wheeler explores gravity and spacetime by applying Einsteins battle-tested theory to both familiar and exotic phomomena--everything from flying tennis balls, to hurling gravity waves from crashing stars, the motion of the planets, and the collapse of a star into a black hole. Its a provocative, revealing, fully engaging scientific journey led by a frontline participa...

Das Projekt MINT-ECho ermöglicht Schülerinnen und Schülern erste Fachpublikationen. Allerdings blieb bisher wissenschaftliche Publikation eine Domäne der Universitäten Institute, setzte somit weitgereifte Ausbildung voraus. Wettbewerbe Seminarfächer ermöglichten zwar dem interessierten naturwissenschaftlichen Nachwuchs „Bühnen“ Präsentation eigenen Forschung, doch „echte Kommunikation“ in einem...

Bring home now the book enPDFd who got einsteins office eccentricity and genius at the institute for advanced study to be your sources when going to read. It can be your new collection to not only display in your racks but also be the one that can help you fining the best sources. As in common, book is the window to get in the world and you can open the world easily. These wise words are really...

In these lectures I propose to push Einsteins principle of coordinate independence to the extreme in order to restrict the possible form of fundamental equations of motion in physics. I start from nearly tautological system theoretic axioms. They provide a minimal amount of a priori structure which is thought to be characteristic of human thinking in general. It is shown how formal discretizati...

We address a subject that could have been analyzed century ago: how does the universe of general relativity look like when it would filled with solid matter? Solids break spontaneously translations and rotations space itself. Only rather recently was realized in various context order parameter has relation to Einsteins dynamical time which is similar role Higgs field Yang-Mills gauge theory. Su...
