How Dinosaurs Matter to Our Survival

Dinosaurs do matter to our future. Of course, I am not suggesting that there will be a time machine where a bespectacled parasaurolophus jumps out and yells, “You must plant Okra, before it’s too late!” … although that would be cool. But thinking about dinosaurs could be helpful to us, as explained in a fascinating little book by Kenneth Lacovara called Why Dinosaurs Matter.

I highly recommend the book, or at least Lacovara’s TED talk on YouTube, but let me debrief you. Consider this a book report that might contribute to saving the planet. It’s the scientific variation of the saying:

Those who cannot remember the past are condemned to repeat it.
Santayana

Dinosaurs Are a Metaphor for Abundance, Not Failure

So what lessons can dinosaurs teach us? If you see an 8.5 mile wide asteroid heading for your neighborhood, bend over and firmly place your head between your knees… or something a little less primitive?

Lacovara’s strongest point is that dinosaurs were an incredibly successful branch on the tree of life. They had zillions of species, ranging from smaller than a chicken to bigger than a Boeing 737. Their reign covered nearly a third of the span of time that multi-celled life has been on earth–three times as along as us mammals. The biggest irony, in fact, is that the word “dinosaur” is used as a metaphor for being outmoded or incapable of change because the dinosaur kingdom’s capacity to diversify and adapt is still unparalleled. They didn’t really “go extinct” as much as being extinguished by an extra-terrestrial bolt of lightning. Besides, technically, they’re not extinct–but we’ll get to that.

Our History of Labor: Strike One! Strike Two!

Exhibit from the earliest factory strike in America, Rhode Island 1824

I suspect many of us are enjoying this three-day weekend: Labor Day, Back to School, End of Summer, Back to Work. Of course, many kids have already gone to school–or some semblance of it, with masks and shortened days–and those who work have probably been doing so and will continue. But any time’s the right time for a Holiday, isn’t it?

The focus of this holiday has always been barbecues and the last little celebration before the chill of autumn begins. Yet, unlike Memorial Day, Veteran’s Day, Easter, Thanksgiving, or Christmas, there’s rarely a thought given to the reason the day itself. Let’s change that.

Let’s talk about Labor.

If you remember your high school American History — or if you google it — the late 1880s always pops up as the “birth” of Labor Movement. This is both true and false. America, like other places with expanding factories and machines in the late 19th century, saw a rise in demands for better treatment of workers. But demands didn’t spring out of nowhere in 1886, the date of the first government-sanctioned Labor Day. History did not begin in 1886. Worker demands go back further than that.

Z is for Zero

The Hindu concept of zero, the void, the circle. Graphic from pparihar.com.

A circle is an infinite number of points all equally distant from a single center. That definition came from Euclid, a Greek, although the Greek’s didn’t use zero. Aristotle was afraid to divide by the void because it wasn’t descriptive of the real world.

The Chinese and the Sumerians used placeholders in their counting, adopting different marks for the tens and the 60s digit, since Babylonians used base 60. But they didn’t have a zero.

The Mayans had a zero–they used base 20–which allowed them to produce large astronomical calculations that generated accurate solar and lunar calendars using only sticks. But their isolation prevented trade, which limited their civilization.

The Romans had zero, of course! Nulla. The Romans had sophisticated plumbing and developed roads that lasted for millenia. But Romans disdained to use nulla in their numbering systems, so even though their business records were hierarchical and detailed, they were limited. Growth is limited if a number like 397,654 is CCCXCVMMDCLIV.

The Arabs developed zero; they developed algebra. But the Arabs learned it from the Hindus.
