Summary

Learn about the woman who discovered pulsars and why they matter; and, why learning styles don’t exist. You’ll also learn about cell-sized robots, in the the first edition of our Microscale Mondays mini-series with Cornell physicists Itai Cohen and Paul McEuen.

In this podcast, Cody Gough and Ashley Hamer discuss the following stories from Curiosity.com to help you get smarter and learn something new in just a few minutes:

I'm Cody Gough.

And I'm Ashley Hamer.

Today you learn about the woman who discovered pulsars and why they matter,

0:11.0

and why learning styles don't exist. You'll also learn about cell-sized

0:15.1

robots in the first edition of our micro scale Monday's mini series. Let's let us

0:19.7

find some curiosity. The discovery of Pulsars was a huge step in advancing our

0:24.3

understanding of the universe. But when the 1974 Nobel Prize in physics was

0:28.8

awarded for the discovery, the person who actually made the discovery wasn't even mentioned.

0:34.0

Thankfully that person finally received recognition in 2018

0:38.0

and the prize may help young scientists the world over.

0:41.0

Plus today's her birthday. So let's learn about Pulsar's to

0:44.9

celebrate the birthday of Jocelyn Bell Bernell. She was a graduate student at

0:49.0

Cambridge University when her team finished building a new radio

0:52.4

telescope at the Mullard Radio Astronomy Observatory.

0:55.2

They started collecting data as soon as it was finished, and her job was to analyze that data.

1:00.3

To the tune of roughly 700 feet of paper records of that data collected each week.

1:07.0

Her job was to spot unusual signals and she found one less than three weeks later, a faint

1:12.3

pulse that disappeared and reappeared every 1.34 seconds on the dot.

1:17.2

After spotting more of these pulsing signals, she and her thesis advisor started calling them pulsars.

1:23.0

Polsars are spinning neutron stars that emit powerful beams of radio waves from their

1:27.4

magnetic poles.
