Jim and Randy discuss Eric Verlinde's theory thermodynamic theory of gravity. This theory purports to explain gravitational attraction and inertia through statistical mechanics.

February 24, 2019 10:54 AM PST

Randy and Jim discuss the chameleon field -- a way to model dark energy with a scalar boson of varying strength.

Randy tells Jim about a way to use an extension of an extension of the complex numbers to reveal the nature of elementary particles.

Randy tells Jim about experiments with Neutrons and Photons in materials that exhibit negative effective mass. Not only do these effects show that the inertial mass of quasiparticles in a material can become negative, they show that these negative mass quasiparticles act like they have negative gravitational mass, as well.

Jim discusses why the world we observe is 4-dimensional with Randy. We discuss anthropic and fundamental reasons why we need 3 dimensions and no more than one time dimension for reasons of complexity, predictability and stability.

Randy explains to Jim theories on how to incorporate a native angular momentum into general relativity.

Randy tells Jim about recent results in the description of the electromagnetic stress tensor in metamaterials. In particular, we discuss the efforts to computationally model the stress tensor in amorphous metamaterials.

Jim and Randy explore the landscape of string theory in the anthropic manner put forward by Leonard Susskind.

CPT Symmetry is a fundamental symmetry in the standard model. Jim and Randy discuss what happens when it is applied to general relativity.

Jim and Randy look at how quantum mechanics is affected by time. Most importantly, what happens when temporal boundary conditions are used to create standing waves in the wave function of a particle?

take it with you

Iphone_trans Listening to podcasts on your mobile devices is extremely convenient -- and it's what makes the podcasting medium so powerful.

You can take your favorite shows and mixes with you anywhere, but to do so requires some quick and simple steps.

Let's walk you through that process together.
step 1:

Click the "Subscribe With iTunes" link in the page's sidebar:


This will require that you have the iTunes software on your computer.

(You can download iTunes here.)
step 2:

Now that you've subscribed to the podcast on iTunes, the feed will display in your "Podcasts" section on the left navigation bar.

Click there and you'll see the show displayed in the iTunes browser.

You can "get all" to download all available episodes or just individual episodes.
step 3:

Plug your mobile device (iPhone, iPad, iPod) into your computer with the Dock Connector cable, and click the device in iTunes's left navigation bar.


Once you have your device highlighted, click "Podcasts" in the top navigation bar and sync the podcasts you want on your device. Click "apply" and the episodes you have downloaded on your iTunes software will sync with your device.
that's it!

The beauty of this process is that now, every new episode of your subscribed podcasts will automatically sync to your device every time you plug it in and open iTunes. You can now take your favorite shows with you everywhere you go.
