GRAVITATIONAL WAVES

So.
before this coming thursday, ye might be interested in refreshing yourself on the topic of GRAVITATIONAL WAVES.

I should probably do an episode on them
OH WAIT I ALREADY DID!

you will need to know four things
1. how gravitational wave interferometers (LIGO) work 

2. The Laws of black hole merger. 

3. The “sound” made by two black holes about to merge together. 

4. The “sound” made by a black hole after it collides.

 

LISTEN TO TWO A DAY, and you’ll be ready for thursday.

Episode 62: Black Bells with Brent Knopf and Matt Sheehy

Take a black hole
and throw something into it.
it doesn’t matter what. A phone. A Neighbour. A Taco. Whatever.

listen when the black bell rings.

listen when the black bell rings.

As it falls in, the black hole will start to emit gravitational waves.
at a very specific tone.

like a bell.

You can tell what kind of black hole it is by the tone its ringing.

On this episode, we’re talking about Quasinormal Blackhole ‘ringdown’.

 

To aide us in our Efforts, we’ve brought in our old friends Brent Knopf (from Ramona falls, and El Vy they were on Stephen Colbert!!) Matt Sheehy (from lost lander)!!! This show is amazing.

Episode 61: Levitating Trains with Erika Ensign

So I was all “hey Darren what should we do a show on.”
and he was like “vortex super conductors”

this is free clip art of thomas the tank engine. it is a train.

it is a train.  Also, it’s past my bedtime.

 

 

i think what he probably actually said was “magnetic vortices in type 2 superconductors”
but by then i wasn’t listening because those words together are awesome.

How was I to know how awesome and complicated this topic is?

but we are super brave.

our guest today is Erika Ensign from twitter , and verity, and lazy doctor who, and uncanny magazine.

Episode 60: Meters of Interference with Ben Acker

AWWW YEAAAHHHH

Apparently if you get enough short-sighted old folks together, and keep them talking: they can, as a group, see better than anyone.

this is an artists rendition of the ALMA interferometer array that we talk about on the show. i got it off wikipedia.

It sounds crazy, but our radio telescopes use it to see very very clearly. The trick called “radio interferometry”, and it’s used to see so deep into the dark, you can’t even IMAGINE!

it’s an AWESOME episode, and our guest is one of our eras greatest podcasters! It’s Ben Acker one of the co-authors of the thrilling adventure hour, which now exists as comic books and live shows.

One of our experts this week is sabrina stierwalt, host of the everyday einstein podcast. So why doesn’t rupinder have a podcast?

Episode 59: Strange Truth and Charming Beauty with Ryan North

THERE IS NOTHING STRONGER THAN THE STRONG FORCE!!

IT IS THE STRONGEST FORCE THERE IS!

THE STRONG FORCE

THE STRONG FORCE

it’s a force that’s so strong that its residue is what sticks positive charges together in a nucleus.

We’re talking QUARKS! we’re talking GLUONS! we’re talking STRANGE CHARGE and the EIGHTFOLD WAY and TRUTH AND BEAUTY and QUANTUM CHROMODYNAMICS.

this episode requires true power. So I’ve chosen our most powerful guest, MR RYAN NORTH! author of THE UNBEATABLE SQUIRREL GIRL, and Qwantz.com. this show is excellent!

Episode 58: Extraordinary Evidence with Kathryn Cogert and Tim Dobbs

How do we know there was a big bang?

This is the Picture of Temperatures/Densities in the Cosmic Microwave Background. It was taken by the WMAP satellite!

i mean: how, specifically do we know?

that’s what we talk about today! EVIDENCE! OBSERVATION RUNS! SCIENCE!

Hubble, The cosmic microwave background, COBE, The Sloan Digital Sky Survey,  WMAP, Planck! we even talk about the future of observational cosmology!

Oh man, it’s so much fun! and our guests? Kathryn Cogert and Tim Dobbs of the Encyclopedia Brunch Podcast!

Episode 57: Two Photons Walk Into An H-Bar with Brian Cross

Okay So.

You make an lensing system which lets you COMPLETELY BATHE a single point in a TON of identical photons.

I took this photo from one of Nicole's Papers. LOOK AT ALL THIS DANG STUFF!

I took this photo from one of Nicole’s Papers. LOOK AT ALL THIS DANG STUFF!

And then? If everything works out, TWO OF THE PHOTONS GET EATEN LIKE A HUNGRY HUNGY HIPPO, and then spit out as a single photon with twice THE ENERGY. it has twice the frequency, so it’s a MUCH DIFFERENT COLOUR from everything around it.

SO CRAZY. SO AWESOME. you can use it to look at stuff inside a cell.

our guest today is a STAR FROM BROADWAY!! so fancy! If you’re in new york around now, he’s in a play called “Desire” at 59e59 theater !

quick note

allo.
sorry i haven’t updated lately. i have been super busy at work and i’m currently on vacation at my parents house which has very very slow internet. remember how crackly that episode on quantum computers with comicbookgirl19? that was recorded here. SLOOWWW INTERNET= BAD QUALITY.

instead i’m going to take the month to do the type of organizing that i don’t have much energy for: booking guests for the next few months and updating the website.

in the meantime, go look at a sunset.
now you know how that works, right?

Episode 56: What “In Tangles” Meant, with Dan Harmon

Oh my what an episode I have for ye today, my wonderful Ti-Phyters!

Dan Harmon has joined us! and he is SOOO CLEVER, oh my what an episode! We spend today talking about QUANTUM ENTANGLEMENT!

this would make a nice painting.

this would make a nice painting.

You might not understand how hard I am working right now to keep from making puns about quantum entanglement.

For instance, I might say something like “As a theoretical physicist Erwin Schrodinger was a peculiar person and also a keen mathematician, and one thing he was often toying with was what we now call ‘Knot theory’. He always had a loop of string or three in his pocket, to play with on any occasion where he had to wait for more than a few minutes. As I said, he was peculiar… he also had a sweet tooth, and often enjoyed sucking on a hard candy after a long meal. One such night, after a lovely dinner out with his wife, he was sucking on a candy and the conversation became heated. He could not speak quickly with the sticky obstruction on his tongue, so he removed it and threw it into his pocket for temporary storage. Unfortunately, it stuck to all of the string and became a rather big mess. It wasn’t the last time he had to unravel a problem in tangled mints.”

you see? This is an example of I’m not the type of joke i’m holding back from telling you. I’m taking one for the team on this one.

This episode is wonderful. one of our best, i think. please enjoy it and remember to listen past the end music for more clever conversation!

Question Barn 8

 

a brand new fun question!

sorry i’ve had trouble publishing lately. super busy and had trouble getting everywhere in the same place.

but question barn!

 

 

fquestionbarn

 

*EDIT*
hey, i just received a correspondence from Nirav Mehta, who commented:

Hi!

I just listened to question barn 8, and thought I’d add my 2 cents here… First, let me say that you an Ken were completely correct to be suspicious of your conclusions in that episode.  It was not very satisfying for good reason, and your intuition was steering you in the right direction.

It all has to do with the fact that the mass of the pi-meson is much lower than the mass of the Higgs. The (neutral) pi-meson has a mass of about 135 MeV, while the Higgs weighs in at a whopping 125 GeV.  When you consider the fact that a nucleon is about 1 GeV, it begins to make sense.  The pi-meson is responsible for the long-range attractive nature of the nucleon-nucleon interaction, and other heavier mesons such as the rho (mass 770 MeV) could play a role in the short-range repulsion.

The Higgs is nearly as massive as a Tellurium atom, and its range should be about 3 orders of magnitude shorter than the range of the pion if we think of it in the Yukawa sense as resulting in a exp(-m*r)/r kind of force.

I am still very interested in Ramiro’s question, as I know very little about the Higgs.  From your conversation, I see no reason why the Higgs can not be the force carrier for some “force”, at lest in the modern sense that forces are a result of some broken symmetry in the Lagrangian.  I liked your discussion about how the Higgs particle is a real, honest-to-goodness excitation of the Higgs field, like the photon is an excitation of the EM field, and that the Higgs observed at the LHC was not a virtual particle, how could it be?!
