I AM SO EXCITED ABOUT THIS MONTH’S EPISODE!!!

1. It’s about the milky way galaxy. Where it comes from, where it’s gonna go, where we are within it, and how we know about it.

2. Erin McGathy is on it! She’s a podcaster and comedian out of LA. She has a podcast called “This feels terrible” , which is fantastic and cathartic! She’s frequently a cohost of the Harmontown podcast. She’s even on twitter and instagram. Anyway i was super nervous until she got on the show and it was lots of fun.

3. Amanda Bauer’s back. hooray! Also Rupinder Brar. It’s a power team. I barely had to edit, their words come out so smooth and so good.

This particular episode has an amazing conversation about science culture. It’s after the end credits and it must not be missed. it’s amazing.

Question Barn 6

Hey tiphyters.questionbarn

i’ve been sitting on this one like an egg, and probably shoulda published it a couple weeks ago.

Katie Mack Is Back.

Doctor Katie Mack. 

the question we answer is from bob

Hello again Ben. I’ve found and listened to the QB episodes. Thanks for the help with locating them.

Since you seem to have ready access to a cosmologist, I’d like to offer for QB a trio of related cosmological questions that have bugged me for some time.

1. How do we know that all the matter in the universe came from the big bang?

2. How do we know that the big bang did not expand into an existing precursor universe? (It seems plausible to me that this may be the case but we have no way to know because the hyperinflation immediately after the big bang and accelerating expansion due to dark energy will permanently keep us outside of the light cone of any event in this hypothetical precursor universe. I’m not fond of unfalsifiable theories…)”

 

cool, cool.

Episode 53: Consistent Variables with Lucy Knisley

There are these stars that pulse.

051Apparently the Polaris, the north star, is one of them.

they pulse over the course of days, so don’t strain your eyes looking for them.

They are called “Cepheid Variables” and they can be used to determine distance between us and far far away galaxies.

Our Guest This week is Lucy Knisley! The comic author who draws her journeys through the world, through her meals, through her lifetime! (I’m pretty proud of that last sentence, linguists) . She has released a book last autumn (it’s great), and there’s another one coming out soon.  Follow Lucy Here and here.

This week’s episode is great!

this episode is SUPER LONG and SUPER AWESOME!

Episode 52: Through The Mirror With Patrick McHale

If you could pass through the mirror into the mirror world

CPT symmetry. Bear with us.  (image from "Over The Garden Wall")

CPT symmetry. Bear with us.
(image from “Over The Garden Wall”)

would the laws of physics differ at all from our own?

Do the laws of physics differ going forwards in time from backwards in time?

Do the laws of physics work differently for matter and antimatter?

Today on the Titanium Physicists Podcast, we answer these questions as best we can. The topic is CPT symmetry!

Our guest this week is exceptional! It’s Patrick McHale, the creator of my favourite cartoon ever “Over the Garden Wall“.  Follow Patrick on Twitter, or on Tumblr.

Episode 51: Tabled Tops with Noah Zimmerman

Mr. Noah Zimmerman joins us to talk about nuclear

this is a visual metaphor for how Nuclear Magnetic Resonance Works... apparently.

magnetic resonance. you know MRIs? “Magnetic resonance Imaging” is what it stands for, “Nuclear Magnetic Resonance Imaging” is what it actually stands for. Essentially, magnets are used to make the nuclei in your atoms stand up and dance.

This is actually one of my favourite episodes to date! We actually manage to explain how NMR works!!

THIS IS SO MUCH FUN!
