Marco Rubio is no Isaac Newton. While true, that statement doesn’t pack as much devastation as one might hope for. I’m no Isaac Newton, and for that I am grateful.

That's why it's cool! If a force is applied to an object that increases or decreases linearly, you get an acceleration that varies linearly. Every time you takeoff on a plane you experience this as this @phyphox.org graph shows. You do something similar when merging onto a freeway. #ITeachPhysics

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free

In clickbait terms: "Everyone was WRONG about Earth's asteroid bombardment!" But that is not the way. New NOVA. Season 53 opens with the story of how asteroids might have initiated life on Earth. It's compelling, and evidence for the model is presented. Nevertheless, I have questions...

My Lessons of Phyz 2025 TPT Yearbook is out. These two are perennial favorite pages.

I scoped out a new shooting location while the auroral numbers looked promising. Forty minutes out of town in a bit of a canyon. Last night’s show stayed low, but I didn’t come away completely empty-handed.

2 photos from my Physics with Phones workshop @aapthq.bsky.social #AAPTWM26 today. A teacher shows his innovative approach to support a spring/mass system given a too-low conference room table. Another shows off the equipment each teacher received. Info: st.llnl.gov/sci-ed/Physi... #ITeachPhysics

TFW Kp is 9 and speed is 1000 km/s but Bz is +35.

In other news, we are less than one month away from Valentines Day, my #ITeachPhysics friends. Are your Scientist Valentines ready to go?

2025: Jersey drones, Notre Dame, JWST, killer robots, UFOs, anti-vaxxism, Dino Birds, AI protein folding, Baltimore bridge collapse, revolutionary war weapons, secrets of the forest, health in Black America, PFAS, Mr. Polaroid, ChatGPT, physics and chemistry crosswords, human, superfloods, and ISS!

We were interviewed for TV! Tell your friends! And tell them that they can still get tickets for our December shows. www.cbsnews.com/sanfrancisco...

Delighted to see folks putting "The Crosswords of Phyz" to use in their science courses. With semester exams taking place, 'tis the season to put these tools to use. Physics, chemistry, biology, and astronomy: there are puzzles for all of them.

At TPT, Cyber25 started Monday and continues through Tuesday. The whole site is discounted. The Lessons of Phyz are discounted even further. Now's the time.

Some scholars believe local TV news broadcasts intend to scare you so you’ll stay tuned in. Last night, mine warned viewers that 15% of November traffic deaths in MT occur Thanksgiving Week. “Stay safe out there!” Should I be frightened or encouraged this week? Justify your answer.

Did I spend the past few days crafting a question set to accompany episode 1 of The American Revolution? All 112 minutes? One hundred questions? Priced at: Free? Yes. Tell your history colleagues. The American Revolution - 1. In Order to Be Free [PBS] www.teacherspayteachers.com/Product/The-...

Eos comes up, it’s Tuesday evening.

She’s got X-ray vision that sees straight through the BS pedaled by the merchants of doubt. And she brings the receipts.

In case you suddenly find yourself (and/or your students) interested in northern lights / aurora, here’s a well-crafted documentary. And I have questions. Aurora: Fire in the Sky www.teacherspayteachers.com/Product/Auro...

Some phone shots from last night’s show over Bozeman (6pm-11pm).

Minding the gap: your students have little awareness of things that happened more than a decade ago. ISS might be something they should know about. It’s a good origin story well told, and I have questions. Operation Space Station: High-Risk Build www.teacherspayteachers.com/Product/Oper...

Asheville, Camp Mystic, and Valencia ... superfloods. "I'm often asked if this is a harbinger of things to come. My response would be it's already here." NOVA has answers; I have questions. www.teacherspayteachers.com/Product/Supe...

Fairy Lake on the last day it was going to be easy to get there for a while.

Join us for the next AAPT Virtual Coffee Hour on "An Evening with Paul Hewitt" with presenters Paul Hewitt and John Suchocki, Conceptual Academy on November 18 at 7:30 pm EST. This event is open to the public. ow.ly/E25v50XbSZA #AAPTCoffeeHour #PhysicsEducation #ITeachPhysics

Join me for a live AP Physics 1 Kahoot! for Unit 2: Forces and Translational Dynamics. My best guess is that it will last for roughly 1 hour. See you on Tuesday, October 28 at 7pm ET! youtube.com/live/Tm9Vetg... #apphysics1 #unit2 #kahoot #iTeachPhysics

All five episodes of PBS/NOVA/BBC’s Human are now streaming. Masterfully done, and having a woman hosting the show does make a difference. For the better. How did Homo sapiens outlast all other human species? I have … 191 questions. Human [PBS NOVA] www.teacherspayteachers.com/Product/Huma...

One of civilization’s most profound and revolutionary ideas didn’t come from an educated elite. It came from inside these dark and miserable mines through the copying and innovating of lowly migrant workers. I have questions. www.teacherspayteachers.com/Product/Huma...

Our ancestors crossed Beringia to get to a land of short-faced bears, mammoths, and a grass called teosinte. They turned the bear hug against the bear, harvested mammoths, and turned that grass into corn. It was the end of the nomads. I have questions. www.teacherspayteachers.com/Product/Huma...

Our Neanderthal encounters are part of a wider pattern that always goes the same way: the survival of our species leading to the demise of everyone else. Extinct species of humans have been assimilated by Homo sapiens. We are the Borg. www.teacherspayteachers.com/Product/Huma...

Just throwing a bull elk wrench into your feed. Take a look at that drop tine!

I had a nice time in Yellowknife, NWT a few weeks ago. When you’re under the oval, the aurora can dance with vigor at KP 1.

As we find ourselves in October, are #ITeachPhysics folks in Inertia? … INERTIA www.teacherspayteachers.com/Product/A-Bu...

Homo sapiens: the last humans to evolve and the only ones to expand across the globe. Episode 2 of "Human" traces our journey from Africa to Australia—through deserts and rainforests, and examines Homo floresiensis, human "hobbits." I have questions. www.teacherspayteachers.com/Product/Huma...

Always delightful when another #ITeachPhysics instructor discovers the unexpected engagement power of these crosswords.

NOVA is back. The BBC’s five-part series, Human premiered on Wednesday. #ITeachBiology might work this series into their courses. Part 1 is Origins. paleoanthropologist Ella Al-Shamahi has answers. And I have questions. Human - 1. Origins www.teacherspayteachers.com/Product/Huma...

My early studies in surface tension and thin film interference.

If you're a proud #ITeachPhysics -er and mid-September finds you with a notion for motion, take a look at this collection. There might be something in there your students will find engaging. www.teacherspayteachers.com/Product/A-Bu...

To the best of my knowledge, this injustice was never rectified. #WhatAWorld

Not the auroral storm I’d hoped for, but I did my best with what I had.

The spectrum of school year start dates ranges from July to September across the country. So Teachers Pay Teachers holds two Back to School sales each year. One at the beginning of August, and one at the end. The BTSBONUS25 sale will be August 26-27. www.teacherspayteachers.com/store/the-le...

Playtime on the Katmai coast.

The puffins were plentiful in Kodiak.

Sitting on a 5-gallon bucket in Geographic Bay on the Katmai coast. I’m watching the bears as they take salmon from the river. And yes, they do get that close. But I am neither salmon nor bear, so they are not interested in me.

@barnettdreyfuss.bsky.social was a shining star long before she gained national recognition. I was always delighted to be illuminated in brilliance of her glow.

I am not ready for what I’m just going to call BTS25 (and I’m retired!) The good people of TPT are, though. Because some districts start unreasonably early these days. So everything’s discounted at least 5%, and many resources are discounted 25%. www.teacherspayteachers.com

A collection of cleverness, and commitment to the bit.

Today’s pro-tip, that may not be welcome here on BlueSky. If you have the #Lyft app on your phone, delete it now. Ride to airport scheduled two days ago. Driver identified. This morning? No driver, no Lyft. An hour after the scheduled pickup, Lyft canceled the ride.

She’s a firehose of facts and factory of debunkery. I’m beginning to appreciate the addictive quality of short form video via her work. Wow! bsky.app/profile/drje...
