My new favorite sticker! But honestly our sticker game is 🔥
If you are at CASE in Palm Springs, stop by to say hello!

A hand holding a sticker that says Live Laugh Graph with a background of an upwardly swooping graph. In the near background to the right is a big sign that proclaims Enter to Win! with additional images and text that are unreadable at this range. In the farther background to the right, there is a table with a teal tablecloth and a Vernier Science Education logo, with items on the table.

I dunno...Mo is a pretty important part of our team.
Image of a gray plushie shaped like a Vernier Go Direct Motion Detector, with a cute, smiling cartoon face. The Mo plushie is wearing a headset with a microphone, ready to take orders on the phone, and is working at a tiny blue laptop (actually a pad of post-it notes) that has a very tiny computer mouse attached to it)

Post your last photo of DC to show what a hell-hole it is.
This is Audi Field in Washington, DC. It is pretty full of soccer fans, none of whom are rioting or being violent in any way.

Our office seismograph picked up the Kamchatka quake last night. We don’t know why the shaking lasted so long (each horizontal trace is 1 hour, so more than 2 hours of shaking). Any experts around who can explain?
Image of a computer screen showing multiple horizontal traces from a seismograph. There are 24 black traces on a white background. About a third of the way from the top, a big black blob of violent shaking is depicted just to the right of center. The remainder of that trace and most of the following two traces show nearly continuous (comparatively) low-frequency vibrations. Below that, most of the lines are pretty smooth, except for another, lower amplitude black blob midway down on the right. The traces at the very bottom show a few vibrations that are characteristic of daily human motion and nearby heavy vehicular motion, similar to a few traces at the top of the image.

I set up some pyranometers on the roof today. Pyranometers measure the incident radiant energy, in W/m^2. You might use one to determine efficiency of a solar panel (we have lots of those in the roof too). In this case I wanted to compare the measurements of sensors encased in different housings.
A woman wearing a yellow t-shirt squints in the sun while sitting on a deck. Behind her on the deck are some gray boxes with coiled-up cables and a flat white object with six small black things arranged neatly on it. The small black things are pyranometer sensors. A flat white object is on some fake-wood decking. There are six black pyranometer sensors arrayed on the white object, each connected to a black coil of wire and a small gray box. A larger, open-topped black plastic box sits nearby. The black box is a good size to hold all the other stuff inside it.

Sometimes I need to get readings with different sensors and compare them. In this case, measuring rotation rate two ways.

This first panel of a Chuck Mullin (@charlubby on other social media) comic reminds me of every Friday at 4 PM during my teaching career.
Five stars, no notes.
Comic panel of a pigeon face down on an orange sofa. There is a pale blue “FWOMP” right below the pigeon. The pigeon isn’t collapsed. Instead they are in a posture like standing up, but positioned tipped over face down on the sofa. There is a pillow on the sofa near the pigeon’s head but the pigeon’s head is not resting on the pillow. There is a “low battery” icon above the pigeon’s head that is mostly white with a tiny sliver of red at the left end. The speech bubble of the pigeon reads “ugh, I’m so burnt out”

Exciting day at work today!
Photo of a white person’s left hand with a bunch of hailstones on it, from pea-size to dried chickpea-size. The background is a hail-covered area of concrete pavement.

Nice rainbow this afternoon!
Photo is about 3/4 sky, and the bottom 1/4 is trees and the cars in a parking lot. Reaching about a third of the way up the frame is a rainbow that spans the majority of the width of the frame. The sky is mostly clouds, with a little bit of blue at the top left.

If you follow Vernier on social media, you can download some valentine cards featuring Mo the motion detector!
Valentine which is a rectangle divided into a left and right half. The left half has the Vernier Science Education logo in white against a pink background with red hearts, tiny yellow 4-pointed starbursts, and some illustrated Vernier sensors. The right half has the face of Mo the motion detector with hearts instead of eyes. Mo’s little stick figure arms are holding what looks like a pale blue candy heart at the lower right of the image, and the candy heart has the words I <3 science on it.

Meme of the blonde white woman who looks skeptical in the first photo with her eyebrows drawn down and her lips clamped together hard, and the same woman looking interested in the second photo with her eyes wide, eyebrows up, and face relaxed. The first image (the skeptical one) has text in classic meme font “impact” that says “mass hanging from spring hanging from force sensor” and the second image (interested expression) has text in the same font saying “the force sensor hangs from the spring.”

This is a bridge along the Laugavegur trail in Iceland. I’m the one in the middle.
A last wooden bridge made of two yellow steel beams with wooden slats laid across them. The railings at about 1m tall on each side look insubstantial. The bridge crosses a gully of grey stone. There is bright green moss and small plants on the far rock wall and you can see the trail going off to the left on the far side. The rock wall continues upward in the background. There are three women on the bridge wearing backpacks and carrying hiking poles, facing to the left and also toward the camera. I am the one in the middle, wearing a bright pink shirt, a blue vest, and blue pants, and a hat.

Ugh. This is never a good temperature.

4 F is -15.5 C, and 19 F is -7 C.
Screen shot of part of the weather app from iPhone. It has the time, 7:29, the location, St.Louis, the temperature, 4 degrees, which is in Fahrenheit, and also indicates Sunny weather and a high of 19 degrees Fahrenheit. 4 F is -15.5 C, and 19 F is -7 C.

New personal best deadlift! 175 lbs (~80 kg of mass)

Here is a short clip of me lifting up the heaviest weight I have ever lifted up (to my knowledge). I don’t move it very far, but I am proud that I can do it. It is 185 pounds (84 kg of mass). I did two sets of 6 with this weight.

I was doing an Atwood’s machine today at work. I bought a couple different types of string to see if there is a difference. This test was with 0.5 mm linen thread. It was pretty good.
On the right side, a Vernier Go Direct Photogate with an attached 10-spoke pulley is at the top of the frame. A thin, light-colored string goes over the pulley and the left side of the string has a brass hook with some masses on it. In the left side is a plushie of Mo, the Vernier Go Direct Motion Detector with a face and tiny arms. One of Mo’s arms appears to be placing a small mass on the brass hook.

Auroras are freakin amazing.
A horizon glowing with the last vestiges of sunset lies below green streamers of aurora borealis mainly diagonal across the night sky.

Do you have a Go Direct Motion Detector? Are you at #NSTA24? I have a few lab coats for Motion Detectors available if you want one. Find me at the Vernier Science Education booth!

@astrokatie.com I’ll be in the Vernier booth in the exhibit hall at AAPT. Would you be willing to stop by and sign my copy of your book?

The chairlift was delightful!

Two days ago I climbed a heck of a lot of stairs. Today I am planning an easier uphill route. We’re going to take a chairlift to a high viewpoint in Budapest!
Photo of a lot of stone stairs, mostly even, with a stone wall on the left side and a railing on the right. The surroundings are a woods, and you can see the sun glimmering from behind the trees at the top of the image. In the center of the image, a woman wearing blue is sitting on the stairs, giving a thumbs-up. She is wearing a cap with a brim, holding hiking poles, and you can see backpack straps.
