Doing Without Dark Energy

Three mathematicians have a different explanation for the accelerating expansion of the universe that does without theories of “dark energy.” Einstein’s original equations for General Relativity actually predict cosmic acceleration due to an “instability,” they argue in paper published recently in Proceedings of the Royal Society A.

200 universities just launched 600 free online courses. Here’s the full list.

If you haven’t heard, universities around the world are offering their courses online for free (or at least partially free). These courses are collectively called MOOCs or Massive Open Online Courses. In the past six years or so, close to 800 universities have created more than 8,000 of these MOOCs. And I’ve been keeping track…

Mapping the optimal route between two quantum states

As a quantum state collapses from a quantum superposition to a classical state or a different superposition, it will follow a path known as a quantum trajectory. For each start and end state there is an optimal or “most likely” path, but it is not as easy to predict the path or track it experimentally as a straight-line between two points would be in our everyday, classical world.
