Symphony of Science: 'Our Place in the Cosmos' (ft. Sagan, Dawkins, Kaku, Jastrow)

"Somewhere, something incredible is waiting to be known." -Carl Sagan. Here's the third movement of the growing Symphony of Science, a series of songs that use scientists' spoken voices auto-tuned to make them sing. In this latest installment, the focus is again on the vastness of the cosmos and our place in it. The video also includes a few clips from my favorite film of all time, Koyaanisqatsi (more on that later this week).

If you're a fan of the original song ("A Glorious Dawn" featuring Carl Sagan and Stephen Hawking), you can now buy it on vinyl from Jack White's record company. It's only six bucks (shipping included!), and the B side features replicas of the Voyager Golden Record's engravings. It's made of vinyl, not gold, though.

You can download free MP3s and learn more at SymphonyOfScience.com. See also: We Are All Connected.

Lyrics

[Narrator]
With every century
Our eyes on the universe have been opened anew
We are witness
To the very brink of time and space

[Robert Jastrow]
We must ask ourselves
We who are so proud of our accomplishments
What is our place in the cosmic perspective of life?

[Carl Sagan]
The exploration of the cosmos
Is a voyage of self discovery
As long as there have been humans
We have searched for our place in the cosmos

[Richard Dawkins]
Are there things about the universe
That will be forever beyond our grasp?
Are there things about the universe that are
Ungraspable?

[Sagan]
One of the great revelations of space exploration
Is the image of the earth, finite and lonely
Bearing the entire human species
Through the oceans of space and time

[Dawkins]
Matter flows from place to place
And momentarily comes together to be you
Some people find that thought disturbing
I find the reality thrilling

[Sagan]
As the ancient mythmakers knew
We're children equally of the earth and the sky
In our tenure on this planet, we've accumulated
Dangerous evolutionary baggage

We've also acquired compassion for others,
Love for our children,
And a great soaring passionate intelligence
The clear tools for our continued survival

[Michio Kaku]
We could be in the middle
Of an inter-galactic conversation
And we wouldn't even know

[Sagan]
We've begun at last
To wonder about our origins
Star stuff contemplating the stars
Tracing that long path

Our obligation to survive and flourish
Is owed not just to ourselves
But also to that cosmos
Ancient and vast, from which we spring

History
The Queen of Code: Remembering Grace Hopper
By Lynn Gilbert, CC BY-SA 4.0, Wikimedia Commons

Grace Hopper was a computing pioneer. She coined the term "computer bug" after finding a moth stuck inside Harvard's Mark II computer in 1947 (which in turn led to the term "debug," meaning solving problems in computer code). She did the foundational work that led to the COBOL programming language, used in mission-critical computing systems for decades (including today). She worked in World War II using very early computers to help end the war. When she retired from the U.S. Navy at age 79, she was the oldest active-duty commissioned officer in the service. Hopper, who was born on this day in 1906, is a hero of computing and a brilliant role model, but not many people know her story.

In this short documentary from FiveThirtyEight, directed by Gillian Jacobs, we learned about Grace Hopper from several biographers, archival photographs, and footage of her speaking in her later years. If you've never heard of Grace Hopper, or you're even vaguely interested in the history of computing or women in computing, this is a must-watch:

Why Are Glaciers Blue?

The bright azure blue sported by many glaciers is one of nature's most stunning hues. But how does it happen, when the snow we see is usually white? As Joe Hanson of It's Okay to Be Smart explains in the video below, the snow and ice we see mostly looks white, cloudy, or clear because all of the visible light striking its surface is reflected back to us. But glaciers have a totally different structure—their many layers of tightly compressed snow means light has to travel much further, and is scattered many times throughout the depths. As the light bounces around, the light at the red and yellow end of the spectrum gets absorbed thanks to the vibrations of the water molecules inside the ice, leaving only blue and green light behind. For the details of exactly why that happens, check out Hanson's trip to Alaska's beautiful (and endangered) Mendenhall Glacier below.
