Rain Bombs

I have seen these in the desert southwest, whose big skies often let you see the weather in all directions. I saw a rain bomb drop onto Monument Valley Navajo Tribal Park years ago, and snapped the photo I used for the product cover.

With climate destabilization and warming, rain bombs are likely to increase in frequency and intensity.

From high-tech simulations and drone expeditions into thunderclouds to possible links with climate change, join investigators on the cutting edge of research to discover what's truly behind these terrifying "rain bombs" and how we can protect ourselves from their growing power. 

Ancient Skies

My first course in physics was my high school Project Physics corse. Project Physics was Harvard's post-Sputnik physics curriculum. The more prominent post-Sputnik physics curriculum was developed by the Physical Science Study Committee (PSSC). 

PSSC was a mathematically rigorous curriculum intended to foster a generation of scientists and engineers capable of competing with the Soviet Union's scientists and engineers. Project Physics took more of a humanities-based approach, steeped in history and personalities.

Through a bit of trickery that I shouldn't have been able to get away with, I managed to take Project Physics in 11th grade and PSSC Physics (at another campus) in 12th grade. (Physics had sunk its hooks into me early.)

I loved both courses, but preferred Project Physics. As I watched Ancient Skies, I was reminded of my fascination with the history of science that was a feature of Project Physics. And my Close Personal Friend® Phil Plait is featured throughout the series. Phil was a classmate at The University of Michigan (a proud employee of Parcheesi's Pizza while I worked at Wazoo Records), and a fellow traveler in the James Randi Educational Foundation's Amazing Meetings and the Amazing Adventure in the Galápagos.

With breath-taking CGI, beautiful landscape footage and some of the world's most important astronomical artifacts, Ancient Skies looks at the cosmos through the eyes of our ancestors, and our changing views of the cosmos throughout history.

Return to the Moon

NOVA premiered this episode less than a week after the Integrity capsule splashed down. That's as "breaking news/ripped from the headlines" as it gets for NOVA.

RETURN TO THE MOON at TPT

A half-century after American astronauts walked on the Moon, NASA and its international partners are taking the dream of Apollo a giant step further. In the coming years, the Artemis missions – named after Apollo's twin sister in Greek mythology – aim to bring astronauts back to the Moon and establish a lunar space station for scientific and commercial exploration. Follow the four members of the Artemis II crew as they embark on a perilous 10-day journey to orbit the Moon, venturing beyond Earth orbit for the first time since Apollo and farther into the Solar System than any humans have gone before. And get an inside look at the preparations needed to overcome the extreme engineering challenges of human-crewed spaceflight, all the way from launch to splashdown.

Mammal Origins

 

MAMMAL ORIGINS at TPT

Uncover the surprising ancient origins of mammals, a story that began long before the dinosaurs' reign. Surveying Earth's tumultuous past reveals how some of our earliest ancestors, the therapsids—creatures that looked like reptiles but were starting to develop mammalian traits—survived multiple global catastrophes. Through remarkable adaptations like burrowing and the emergence of warm-bloodedness, they forged a lineage that persevered against all odds. Fascinating fossil clues and cutting-edge science reveal how a small, resilient group of animals faced extinction events, outlived giants, and ultimately gave rise to the diverse world of mammals we know today, including us.

Can Dogs Talk?

CAN DOGS TALK? at TPT

Imagine a world where your furry best friend could tell you exactly what they're thinking. A growing number of dog owners claim this is already happening, thanks to innovative word buttons that seem to unlock a new realm of canine communication. But are these dogs truly understanding what we’re saying—and talking back? Are they really thinking creatively, applying words in new contexts? Or is this just clever conditioning? To find out, scientists are conducting the largest animal communication study in history, analyzing millions of button presses from thousands of dogs worldwide. Witness astonishing moments that challenge our assumptions about animal intelligence, from dogs that seemingly engage in conversations to those who learn new words with incredible speed. Prepare to question everything you thought you knew about the minds of dogs and discover just how far their linguistic abilities might stretch.

Asteroids: Spark of Life?

Explore a revolutionary theory suggesting that these violent collisions provided the essential ingredients – water, minerals, and energy – needed for life to ignite on our planet. Discover how scientists are unearthing evidence from lunar rocks and ancient impact craters, revealing that the very objects known for extinguishing life might have actually sparked it.

The American Revolution

In 1990, Ken Burns made a name for himself with his series, The Civil War. Since then, he has created many celebrated historical documentaries. In 2025, he (and his team) released The American Revolution.

I appreciate that the Civil War gets more attention than the Revolutionary War. But the Revolutionary War seemed a bit too marginalized in my own recollection of US History coursework. And too simplistic in my memory. So I was grateful to see this 12-hour documentation produced by Team Burns.

So of course, I have questions. As each episode runs well over 100 minutes, I have about 100 questions for each episode. This might seem like a heavy load for students watching each episode, but it is not. 

Each question requires a response that takes very few seconds to complete. Students can relax and listen for most of the screening time, but the questions will help maintain their focus. Most quickly become adept at pre-reading the next question up, and are ready to pounce when the answer comes up.

THE AMERICAN REVOLUTION Complete at TPT

Thirteen American colonies unite in rebellion, win an eight-year war to secure their independence, and establish a new form of government that would inspire democratic movements at home and around the globe. What begins as a political clash between colonists and the British government grows into a bloody struggle that will engage more than two dozen nations and forever change the world.

Chemistry Crossword Puzzles [Essential Chemistry-aligned]

These crossword puzzles are intended for first-course students. Topical terms constitute the core of the word list. They come from PASCO Scientific’s Essential Chemistry textbook. Additional terms (to fill in the grid space) lean toward science, but sometimes wander into simple mathematics, general knowledge, technology, pop culture, geography, initialisms and acronyms, Roman numerals, or randomness.

Although this kind of activity may seem too simple for high school science, I discovered that it is not. I wrote a post detailing my surprising findings: Crosswords that work in college-prep courses.

I created these puzzles for use in high school courses. Because I was using crossword creator software, I chose to build as robust a crossword as possible. The more crosses, the better. The fewer blank spaces on the grid, the better. The chemistry topic vocabulary served as the core of the word list. I added “fair-game” terms to fill the gaps. While competing crosswords might have 20-30 words with a few dozen crosses, each of these has over 100 words with over 150 word crosses.

ChatGPT is Becoming a Religion

It's been a few years since ChatGPT and Large Language Models exploded onto the scene (c. November 2023). But its roots went back further than that, and its applications have gone beyond students cheating at school.

Tech reporter, Taylor Lorenz, offers her take on enterprise. The information comes fast and furious, so fasten your seatbelt.

ChatGPT is Becoming a Religion

A new form of techno-spirituality is spreading like wildfire across the internet. Thousands of people are claiming that ChatGPT is sentient and that the AI is a type of all-knowing God, or that it has been sent from the future or an alien civilization to save us. 

Is this a new form of religion or mass psychosis? In this video, I dive deep into the rise of ChatGPT/AI worship and unpack how decades of pop culture influences have primed us to view technology as God-like. I dig into how tech became fused with spirituality, Silicon Valley founder worship, what the academic research on this topic says, and how we can stop more people from falling victim to this cycle before it's too late.
