The first episode of the new joint podcast, "Questioning the Cosmos" is online. Check it out and stuff!

By now I'm sure your skeletons have blown away in the wind in anticipation of an update. The Thought Experiment will live on in the Internet's bowels for weeks to come, but a new contender has arisen. The "Question the Cosmos" podcast is its spiritual successor and we've launched a new blog to support it. Indeed, a new youtube page and twitter account for those so inclined.

So go and check it out before I take another 2 years to add an update here!

Ok I've been too lazy for too long. This weekend before I head off to CERN I'll post the first of a few interviews I did at the American Physical Society. Up first? How about Phil Plait?

edit: I will have to upload them when I return to the US on the 15th, since I don't have the software on my laptop to do so. In other news,

Shedding Light on Dark Matter Powerpoint

I've added as supplementary material here, my actual printed powerpoint presentation slides for the 4-part 50-minute lecture. Although the incredible animation effects that went into the Barry Bonds segment aren't alive on the .pdf document, the images provide backup to all those times that I say, "search this or that." It may also be helpful to scroll through it while listening.

Also, I may as well attach my paper, Dark Matter Versus Modified Newtonian Dynamics, for those who are interested in my segment in the series that covered it. I went over the topic briskly and may have skipped some things, so the paper is also in this post for everyone to gawk over.

Shedding Light on Dark Matter (part 4)

In the fall I'm giving a lecture series on topics ranging from the history of the universe to time travel. Dark Matter is one of those topics.

In this final part of the series, we go over a very brief history of Dark Matter and some of its competitor theories, such as Modified Newtonian Dynamics (MOND) and Massive Compact Halo Objects (MACHOs).

Shedding Light on Dark Matter (part 3)

In the fall I'm giving a lecture series on topics ranging from the history of the universe to time travel. Dark Matter is one of those topics.

In this third of 4 part series, we go over candidates for dark matter particles and detection techniques.

Next installment goes over the history of Dark Matter and its competitors.

Shedding Light on Dark Matter (part 2)

In the fall I'm giving a lecture series on topics ranging from the history of the universe to time travel. Dark Matter is one of those topics.

In this second of 4 part series, I do a thought experiment involving Barry Bonds and detail the origin and nature of matter.

Next installment deals with detecting candidates of Dark Matter.

Shedding Light on Dark Matter (part 1)

In the fall I'm giving a lecture series on topics ranging from the history of the universe to time travel. Dark Matter is one of those topics.

In this first of 4 part series, I give a brief introduction and go over distinguishing Dark Matter from what isn't Dark Matter.

Next installment deals with properties of matter and Dark Matter and how they apply to baseball.

The Strong Nuclear Force

The Thought Experiment podcast has been kind of stagnant lately. Largely because I've been so busy here on campus with Dark Matter research and so on and hopefully this video, a talk I gave recently on the strong nuclear force that holds atomic nuclei together, can shed some light on just how jam packed my schedule has been these last few days.

The recording quality is rather lacking, yes, but my placement of the microphone in the lecture hall I guess was less than strategic. Plus it has more buttons to confuse an astronaut!

Enjoy!

Quantum Tunneling

Tunneling is a very, very mathematical process by which a particle can 'leak' out into its surroundings. This has to do with all sorts of things called wave functions, probability densities, and so on, but the real aspect behind them is: how can we use this for our macroscopic advantage?

Intro to Quantum Mechanics

Ironically, the delay for this week's quantum mechanics podcast was brought on by quantum mechanics homework. In any case, this week I delve into the beginnings of what quantum mechanics is, opening up the playing field into the zany world of the small.
