Ep. 468: Simulations for Science and Fun

Astronomers depend on simulations to study the Universe. From relatively straightforward orbital simulations to vast simulations that try to recreate the large scale structure of the Universe from the Big Bang. Today we’re going to talk about some of those simulations, as well as tools you can use simulate the Universe.

Ep. 466: Origins of Zero (0)

We depend on zero for our math to work right, but this number was actually invented in fairly recent times. Why do we need zero? Was it inevitable?

Ep. 436: Common Misconceptions in Probability

Human beings are bad at many things, but we’re particularly terrible at understanding probability in a rational way. We underestimate, overestimate and generally mess up probability. We’ll try to fix it here, but we’ll surely fail.

Ep. 435: The Butterfly Effect

Small changes can have a big impact. But can a butterfly’s wing-beat in the Amazon really impact the weather halfway across the world? And where do small changes have no impact?

Ep. 427: Click Bait vs Clear Science

Did you hear that Dark Energy doesn’t exist any more? Neither does Dark Matter? It turns out that NASA recalculated the Zodiac and now you’re an Ophiuchan! Science is hard enough, but communicating that science out to the public when there are publications hungry for traffic is even harder! Here’s how to parse the click-bait science titles.

Ep. 417: Error 417 – Expectation Failed

In all fields of science, sometimes more is learned when you fail at what you’re trying to do than when you succeed. So what new science discoveries have failed expectations given us in astronomy?

Ep. 383: Approaches to Absolute Zero

The coldest possible theoretical temperature is Absolute Zero, this is the point at which no further energy can be extracted from a system. How are physicists working to get as close as possible to this extreme cold?

Ep. 336: Units of Measure

How heavy is a kilogram, how long is a second? How warm is a degree? We measure our Universe is so many different ways, using different units of measurement. But how do scientists come up with measurement tools which are purely objective?
