Searching for contentment
This is what fascinates me most in existence:
the peculiar necessity of imagining what is, in fact, real.

Four Hundred Souls: A Community History of African America, 1619 – 2019 edited by Ibram X. Kendi & Keisha N. Blain
Beautifully narrated by a full cast; full list of contributors & and cast of narrators⩘
From the publisher:
Four Hundred Souls is a unique one-volume "community" history of African Americans. The editors, Ibram X. Kendi and Keisha N. Blain, have assembled ninety brilliant writers, each of whom takes on a five-year period of that four-hundred-year span.
The story begins in 1619—a year before the Mayflower—when the White Lion disgorges "some 20-and-odd Negroes" onto the shores of Virginia, inaugurating the African presence in what would become the United States. It takes us to the present, when African Americans, descendants of those on the White Lion and a thousand other routes to this country, continue a journey defined by inhuman oppression, visionary struggles, stunning achievements, and millions of ordinary lives passing through extraordinary history.
This is an immense, important, and impactful work, sweeping in scope, while also incredibly intimate in the sharing of insights by the scores of contributors into each of the five-year periods addressed between 1619 and 2019. I learned so much from listening to these essays and poems, which led me to deeply feel a range of emotions, including astonishment, horror, shame, sadness, fury, hope, awe, appreciation, inspiration, and gratitude. Our world is richer for this compilation.

A fresh way of looking at our world
J. Richard Gott, an astrophysicist at Princeton, Robert Vanderbei, a mathematician at Princeton, and David Goldberg, a cosmologist at Drexel University in Philadelphia have created a new map of the Earth that they believe is the most accurate flat map of Earth yet. Although I'm showing both sides above, the two halves can be better pictured back to back. In that configuration, any point on one side can be traced to the corresponding point on the other side by simply flipping the map. What an awesome map they have created!

Living in the Rockies
For me, one of the most beautiful things to experience on Earth is early morning sunshine brightening a fresh blanket of snow!
Also, a tidbit of news from this morning: 73.2%⩘ of the lower 48 states is currently covered in snow to an average depth of 6″, an 18-year high.
Dedicated to my good friend Thomas Hey'l
who has inspired me to look at design more deeply
and to take even more care about precision.
Sharks kill an average of 10 people per year. People kill around 100,000,000 sharks per year 1. People also kill approximately 425,000 people per year, topped only by mosquitoes, which kill about 725,000 people per year 2.

People walk at an average pace of about 2.5 miles per hour.
Meanwhile, light travels about 186,000 miles per second, or about 11,160,000 miles per hour. It would take light about 0.13 seconds to travel around the Earth,
1.3 seconds to travel the 238,900 miles from the moon to the Earth,
8.3 minutes to travel the 93,000,000 miles from the sun to Earth, and 1.3 hours to travel the 890,000,000 miles from the sun to Saturn. To get a glimpse of an idea of just how far away Saturn is, see If the Moon were only 1 pixel⩘ by Josh Worth.
At the scale of the solar system, the Earth is a spec of dust. 1,300,000 Earths could fit within our sun.
Our sun, as big as it is, is just a tiny twinkle of light in a suburb of the Milky Way galaxy. Its light takes about 27,000 years to travel to the center of the Milky Way.
One light year is just short of six trillion miles (5,878,625,000,000). The Milky Way has a diameter of about 100,000 light-years, and contains as many as 400 billion stars, which together create a smidgen of light in our local group of galaxies.
The light of the Milky Way takes about 2,300,000 years to travel just to the nearby Andromeda galaxy. Isn't it amazing that by using our inherent art of visualization, we can be there, instantly, in this moment.
The observable universe is estimated to contain as many as two trillion galaxies. To get more perspective on this eXtreme Deep Field (XDF) Hubble image, see the short video: Hubble Legacy Field Zoom-Out⩘ . Make sure to read the notes, too.

By the way, because of the Earth's spin, if you're standing still at the equator, you're actually moving at about 1,667 km/hour (1,037 miles/hour). The Earth is orbiting our sun at approximately 30 km/sec (67,108 miles/hour). Our sun is orbiting the center of our Milky Way Galaxy at approximately 250 km/sec (560,000 miles/hour). And our galaxy is moving through our universe at approximately 600 km/sec (1,340,000 miles/hour). Hang on!
