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!

Physicists: Vicky Scowcroft, David Tsang

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!

Episode 50: The Death of Spirals with Kat Griffiths

Oh man.
Galaxies are totally amazing.

why are there two types of galaxies? Why are they different colours?

the answer is simple: elliptical galaxies don’t have any baby stars in them.

Because all the gas got blown away or melted.

Ooops.

Today’s guest is Kat Griffiths!

Kat is one of the cohosts of the Verity Podcast (about doctor who), and she’s also a fangirl of epic import.

So much fun.

Also, Sean and Laura are back. it’s fun times.

Episode 49: Parallel Philosophies with Christopher Reynaga

Imagine you go back in time with a couple measuring cups. And you give it to some premathematical cave men. And you give them time to play with the cups. And suppose that, as a result, the cave men have learned the mathematical laws of addition before they know how to count. Plato_and_Aristotle_in_The_School_of_Athens,_by_italian_Rafael

What incredible stories do you think they would come up with about why 2+3=5 and 3+2=5 but 2+5=7?

The mathematical laws of quantum mechanics were discovered (informed by the mathematical laws of classical mechanics, which dictate things like energy conservation) without an underlying physical model. That is to say, we know how to do the math, and we know how to use the math to make predictions, but we’re not exactly sure what the math is describing.

Today, on the Ti-Phy, we’re going to talk about the schools of philosophy for interpreting quantum mechanics. It’s pretty great.

Our guest is an author named Christopher Reynaga. The author of my favourite story ever “I only am escaped alone to tell thee” where Captain Ahab is obsessed with hunting Cthulhu.  It has a line in it that is so marrow-chillingly good: “He is the Christ come to try and deliver us all, and there’s not enough blood in him to save us” ha.

 If perhaps you would like to listen to a pocast version, it has been masterfully read by Graeme Dunlop on the DrabbleCast.
