Benjamin Franklin


As a frequent visitor to pbs.org, I was seeing promotional material for the (then) upcoming Ken Burns' Leonardo Da Vinci documentary. While poking around, I discovered that he made a two-parter covering Benjamin Franklin. So I crafted a question set for that while waiting for the Da Vinci work to air.

Each episode runs about two hours, so this is a considerable piece of work. Each episode is divided into chapters; see product listings for complete details.

Leaving behind his Boston childhood, Benjamin Franklin reinvents himself in Philadelphia where he builds a printing empire and a new life with his wife, Deborah. Turning to science, Franklin's lightning rod and experiments in electricity earn him worldwide fame. After entering politics, he spends years in London trying to keep Britain and America together as his own family starts to come apart.

Benjamin Franklin leaves London and returns to wartime Philadelphia where he joins Congress and helps Thomas Jefferson craft the Declaration of Independence. In Paris, he wins French support for the American Revolution then negotiates a peace treaty with Britain. He spends his last years in the new United States, working on the Constitution and unsuccessfully promoting the abolition of slavery.

Both episodes, bundled and discounted.

Decoding the Universe

DECODING THE UNIVERSE
See how our understanding of nature and the universe has been transformed since the 1970s.

How big is the universe? What is it made of? Are we alone? Questions like these have inspired amazing discoveries that have transformed our understanding of the universe since the 1970s, shedding light on everything from exoplanets to black holes to the mysterious dark matter and energy that rule the cosmos. And closer to home, quantum physicists have discovered the weird laws that govern the subatomic world, unlocking amazing technologies—from the smart phone in your pocket to powerful new quantum computers taking shape in labs today.

How big is the universe? If it began with the Big Bang, will it also have an end? Is there life beyond our planet? Questions like these inspired the launch of Voyager I in 1977 and have driven innovative space research and exploration ever since. Trace ground-breaking discoveries that have transformed our picture of the universe, from an age when we knew of no planets beyond our solar system, to today, when we have evidence of thousands and estimate trillions more. And follow the teams trying to solve two of the biggest mysteries in cosmology today: What are dark matter and dark energy?

When we look at the world at the tiniest scales in the subatomic realm, things get weird – very weird. Welcome to the quantum universe, where particles can spin in two directions at once, observing something changes it, and something on one side of the galaxy can instantly affect something on the other, as if the space between them didn’t exist. Buckle up for a wild ride through the discoveries that proved all of this to be true and paved the way for the digital technologies we enjoy today – and the powerful quantum sensors and computers of tomorrow.

Will there be more episodes of Decoding the Universe? I don't know. Somehow in 2024, my search engine skills are unequal to the challenge of finding out. Someone deep in PBS NOVA HQ knows. I'm hoping more episodes will be added to this collection.

Solar System

 

PBS NOVA has once again teamed up with BBC for another space science miniseries. The Planets (2019) was followed by Universe Revealed (2021).

This year, it was deeper dive into the solar system. You might wonder what was left to document so soon (in space documentary years) after The Planets. What Solar System does is to open things up to include moons and dwarf planets. Suddenly to the topic candidates expand from fewer than a dozen to hundreds. We've been sending probes to explore these words for decades, and researchers have been able to identify and sort unexpected mysteries. 

Ice worlds composed of hot, black ice, volcanic worlds heated by tidal forces, dwarf planets that kiss more than they collide, comets, asteroids, and an unseen cloud of countless worlds. Solar System dives deep into some two dozen worlds in our own neighborhood, including Haumea, Ganymede, Miranda, Pan, Io, Enceladus, Iapetus, Phobos, Ceres, Triton, and Charon. Earth is included in the mix, correctly cast among the "Strange Worlds." Honestly, the more you know about Earth, the stranger it seems.

Thanks once again to my fourth-grade teacher, Mrs. Murphy, for encouraging me to deepen my fascination with the other worlds of the solar system years before the Vikings or the Voyagers.
