Links to lectures by experts in their fields.

In this information age, it is easier than ever to access knowledge in all manner of formats. The simple academic-style lecture yet remains one of the most effective ways of presenting focused research. (Especially when followed by a good Q&A session.)

The information age, with its broad and easy mechanisms of dissemination, has brought with it also an era of noise. Everyone is, or has, their own expert. Let's try to find true experts, recognized and generally accepted in their fields, to see what interesting things they have to say.

Suggested title format: "Title of lecture" [year, if not current], Name, Credentials and/or Venue. Brief synopsis/description. #topic #subject

Consider using links that go straight to the beginning of the lecture (bypassing lengthy introductions) if possible.

In 1929 Edwin Hubble discovered that our Universe is expanding. Eighty years later, the Space Telescope that bears his name is being used to study an even more surprising phenomenon: the expansion is speeding up. The origin of this effect is not known but is broadly attributed to a type of “dark energy” first posited to exist by Albert Einstein and now dominating the mass-energy budget of the Universe. Professor Riess will describe how his team discovered the acceleration of the Universe and why understanding the nature of dark energy presents one of the greatest remaining challenges in astrophysics and cosmology. He will also discuss recent evidence that the Universe continues to defy our best efforts to predict its behavior.
