The Thought Experiment

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.

Quantum TunnelingTunneling 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 MechanicsIronically, 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.

Borel's Infinite MonkeysReturning triumphant for a second season of thought experimenting, we continue on our history of thought experiments into the later 1920s with Borel's mathematical analysis of what happens when you get a ton of monkeys in a room with a ton of typewriters. A Borel of monkeys for sure!Baxiden is by Liquid Tension Experiment

Q&A With Brian GreeneLast week string theorist and physicist at Columbia University, Brian Greene came to my university as a part of a lecture series featuring distinguished lecturers. He did a question and answer session for a small group of us (about 20 or so people), as well as a planned lecture event. This week is the Q&A session.Theme music by Liquid Tension Experiment

Heisenberg's Uncertainty PrincipleWhat can a retired basketball player and a cannon full of paintballs teach us about quantum uncertainty? A lot, actually. Have a listen in on why we can't tell where a proton is at the same time when we know its momentum: the quintessential uncertainty principle. For a link to the blog post I mouth off about, see the exposé on Ramtha and What the Bleep Were They Thinking?New and permenant theme music: Baxiden by Liquid Tension Experiment

The Banach-Tarski ParadoxA mouthful no doubt! This week we go over just how a mathematical universe differs from a physical one on the basis of the Axiom of Choice. More interestingly, if we exploit this paradox, we can clone anything we want with the exact same properties as the original. As per Andrew's note, you can see an example of a fractal here. Really amazing stuff to say the least. Barbarian Horde is by Hans Zimmer

Mach's MachineCourtesy of StanfordErsnt Mach proposed that perpetual motion machines went against common sense. In this solitary episode, I talk about various claims of pseudo-scientific energy companies and talk about why their murky science is, at best, flawed. From tachyon theory of gravity to consciousness-energy, a short list of problems is noted.White Army, Black Baron is by the Soviet National Choir

Can Life Be Patented?A deep philosophical question indeed, arisen from the recent episode of Science Friday's discussion on ethics of cloning. Andrew and I are joined by members of the Skype community in the form of a skypecast in which we discuss the ideas and let the fans of the podcast get a word in as well, live. Despite off-topicness and quality issues (Skypecasts have been under repair as of late), we venture forth into a discussion about whether or not life as we know it or not can indeed by patented.'The White Tree' by Howard Shore
