Summary

Have you ever wondered how your eyes compare to a telescope?  The answer is more surprising than you might think! Today, we will look at the fascinating parallels between the human eye and one of the most powerful astronomical instruments - the telescope.  From lenses and apertures to light detection and color vision, we will explore how these two systems, one biological and the other mechanical, have strikingly similar properties.  Tune in to learn more about how nature's best telescope matches up with cutting-edge technology. This episode is part 1 of a series where we’ll uncover even more intriguing insights about the connections between our eyes and telescopes, so stay tuned! Key Takeaways:  00:00 Intro  01:29 How telescopes inspired me as a kid 06:24 Comparing the anatomy of the human eye to a telescope 12:51 Light sensitivity and resolution in the human eye  17:23 Color vision and polarization  21:03 Historical contributions and confirmation bias 25:41 How to improve our astronomical observations  28:39 Outro Additional resources:  ➡️ Follow me on your fav platforms: ✖️ Twitter: https://twitter.com/DrBrianKeating  🔔 YouTube: https://www.youtube.com/DrBrianKeating?sub_confirmation=1  📝 Join my mailing list: https://briankeating.com/list  ✍️ Check out my blog: https://briankeating.com/cosmic-musings/  🎙️ Follow my podcast: https://briankeating.com/podcast  Into the Impossible with Brian Keating is a podcast dedicated to all those who want to explore the universe within and beyond the known.

Welcome back to my channel.

0:17.0

This is Brian Keating.

0:18.0

I'm the Chancellor's Distinguished Professor of Physics at UC San Diego.

0:21.0

I've been an astronomer for over 40 years and I hope to convey some of that

0:25.1

lifelong learning and loving that I've had of astronomy with some new discoveries that are being

0:29.6

made both in optical astronomy and how astronomy relates to the brain. And to do this we're going to take a tour of the similarities and the differences between the human eyeball and the telescope.

0:41.0

The human eyeball is effectively a telescope that you're born with.

0:44.6

It has all the features of a modern telescopic camera system and will investigate those

0:49.4

as well as some of the fascinating connections between the eye and the brain.

0:53.4

And this is partially in preparation for an upcoming episode of Andrew Huberman's

0:57.6

Huberman Lab podcast, which I've been invited upon, and I plan to talk about these similarities

1:02.2

with Andrew when I do go on this podcast.

1:04.0

Andrew and I have other similarities such as the fact that we were both inspired in some way

1:08.2

to become scientists around the same age by encountering very inexpensive or as Andrew loves to say low cost to consumer tools of science.

1:17.1

In his case it was the aquarium and fish. He loved learning about them he'd collect fish.

1:22.0

For me it was getting a cheap telescope, no bigger than this one,

1:25.0

to explore the mysteries of the universe

1:27.0

as I could perceive them from my home in Dabs Ferry, New York.

1:30.0

So today, I hope to instill some of that inspiration in you, especially your parents out there.

1:34.8

Those who are interested can find a buyer's guy for telescopes on my website.
