Rob Carr @robcarr.bsky.social · 07/08/2026I don't swear because we have pet birds who will hopefully out live me and need to be rehomed. It's easy to teach a parrot to swear. But parrots that do swear are difficult to stop and lessen the chance of adoption. Parrot Tax attached. 000
Rob Carr @robcarr.bsky.social · 16/05/2026@astrohelena.bsky.social A friend saw your presentation at Allegheny Observatory last night. You went way beyond his training and he was very impressed I hope to see you here among the astronomers. I used this book for Earthbound things, but the number of citations in astrophysics are amazing! 000

Rob Carr @robcarr.bsky.social · 12/11/2025@badmedicaltakes.bsky.social Check out Dr. Aliza on Facebook. AI "videos" of female human reproductive anatomy that are more like H. Bosch might have painted on Psilocybin. I'm stupider for having watched. 010

Rob Carr @robcarr.bsky.social · 08/10/2025Nobel Prize in Chemistry Richard Robson is a professor at the University of Melbourne Susumu Kitagwa received his Ph.D. in 1979 from Kyoto University Omar M. Yaghi received his Ph.D. from the University of Illinois Urbana-Champaign They won it for organometallic frameworks. 120
Rob Carr @robcarr.bsky.social · 14/03/2025Blood Moon Total Eclipse. It's Pittsburgh, which usually means horrid seeing for astronomical events. There's a haze & some acrid pollution. I can only see a handful of stars. Around here, that's amazing. Cataract surgery: I can see this without glasses, for the first time in probably 58 years. 🧪🌌🥮 2311
Rob Carr @robcarr.bsky.social · 20/01/2025It's January 20th, the celebration of MLK Jr., and something else I'm pretending to forget about. And this came along: 124946
Rob Carr @robcarr.bsky.social · 13/01/2025Tobor, the 8th Man (8 Man in Japanese translated directly into English) is an android that received the mind of a murdered detective. He smoked to get energy. Yes, this was an actual cartoon children watched, including me. Personally, as a child, I hated adults smoking. 120
Rob Carr @robcarr.bsky.social · 05/01/2025This is why I have sleep problems. The alt text for the image contains the intro from "Pavlov Trains Pea Plants." Yes, it's 5 am and I'm a bit silly. But it gets the point across sussinctly. 🧪🫛 170
Rob Carr @robcarr.bsky.social · 26/12/2024@johnmoffitt.bsky.social I got my 6 y/o niece a small trilobite fossil for Christmas. She's a dinosaur fan. When I explained to her what it was and how old, relative to the dinosaurs she was amazed. The rest of the night, she went around showing people her fossil. 71229
Rob Carr @robcarr.bsky.social · 25/12/2024My 6 y/o grandniece was so thrilled with her trilobite fossil she was going around showing it to everyone at the party. She doesn't have to become a scientist. But I'll give her all the opportunities I can. 🧪🦴 319513
Rob Carr @robcarr.bsky.social · 17/12/2024Look, we all know that I like birds. And somehow no one ever got around to making the Bald Eagle the official National Bird™. But this is what they're working on? Really? Even Cirrus the CAG is annoyed. 010
Rob Carr @robcarr.bsky.social · 08/12/2024There's a certain irony about a biochemist cook failing to get his focaccia bread to brown. Tastes amazing, though! 🧪🍞⚗️ 5454
Rob Carr @robcarr.bsky.social · 06/12/2024I'm a biochemist. I saw this article. It looked interesting and I started reading it. The more I read, the more I started thinking this was nonsense. I wanted to rip it apart, but I thought "What do I know?" I left the tab open to take another look later on. I looked at it again today. 🧵⚛️🌌 010
Rob Carr @robcarr.bsky.social · 25/11/2024I love how the sous vide London broil turns out: flavorful and tender. I got into sous vide mostly because it was using biochemistry and information about bacterial growth to cook my food in a strange way. Cooking something in only 56.7 C (134 °F) for 22 hours is different! 🧪🧑🍳 🧵 140
Rob Carr @robcarr.bsky.social · 23/11/2024I like birds and live with several parrots, including Cirrus in the attached picture. You say "I do NOT like segregation in any way." I oppose segregation, yet I participate in a group on BlueSky that focuses on birds. 🧵 1/n 160
Rob Carr @robcarr.bsky.social · 22/11/2024Let's face it, I'm weird. I do believe Chauncey the Moluccan Cockatoo could remove one of my fingers if he wanted to. So I stay on his good side. 000
Rob Carr @robcarr.bsky.social · 15/10/2024I'm assuming I don't have to explain how bad this New York Post headline is to the people of BlueSky. PS: The AP does not appear to have suggested the headline used by the New York Post. 🧪🌌 3210
Rob Carr @robcarr.bsky.social · 07/10/2024One Pot French Onion Pasta with Gruyer Cheese and Rigatoni. At one point, the rigatoni looked like the drawings of one of the nuclear pastas from a Neutron Star. Except what I thought were drawings of rigatoni were drawings of nuclear spaghetti. I don't know neutron stars or pasta very well. 🧪🌌 131
Rob Carr @robcarr.bsky.social · 22/09/2024There's a picture claiming to be the first picture of a sunset on Mars. It's not. The first picture of a sunset on Mars was taken by a Viking lander. The one I've posted was taken 8/20/1976 by Viking 1. I don't know if it was the first or not. I loved this picture when it was released. 030

Rob Carr @robcarr.bsky.social · 14/09/2024This is the result of the second die. It's still a 37% probability of happening, so it's not significant. I thought 5 and 6 would be over-represented. 5 occurred 108 times, one less time than 3, and 6 occurred 94 times, less than 100 times. More analysis later. 🧪🎲 030
Rob Carr @robcarr.bsky.social · 14/09/2024I copied the data, sorted it in another column, and the spreadsheet counted the number of rolls. I checked the results by simple subtraction from the ordered column. I used the GraphPad Chi-Square test and found that the data was not significantly different from chance. 🎲 🧵 5/n 170
Rob Carr @robcarr.bsky.social · 14/09/2024I ordered two Chaos Dice from DiceMakers.com . Note: The two dice are identical, which means I kept them separate. This is the report on the first die I tested. Based on my idea of fun, I decided to test whether the dice were fair. 🧪 🎲 🧵 1/n 3212
Rob Carr @robcarr.bsky.social · 12/09/2024Are the Chaos Dice from Dice Masters on Etsy statistically fair? I want to find out. It may take a while. Two dice, and at least 600 tosses each. 100
Rob Carr @robcarr.bsky.social · 12/09/2024Got them! Two glow in the dark Chaos Dice from Dice Makers on Etsy. Are they fair? 000
Rob Carr @robcarr.bsky.social · 27/08/2024Your post and Phil Plait's were side by side. You may be on to something. 000

Rob Carr @robcarr.bsky.social · 10/08/2024The Mingo Creek Observatory telescopes. I thought I had more photos of the smaller scope. Watching kids look through them was fun! 🧪🔭🌒 2 of 3 1120
Rob Carr @robcarr.bsky.social · 10/08/2024I (and a lot of other people) had a great time at the Mingo Star Party tonight! It was put on by the Amateur Astronomer Association of Pittsburgh at the Mingo Creek Observatory! 🧪🔭🌒 1 of 2 1171
Rob Carr @robcarr.bsky.social · 01/08/2024I love this graph. We used to raise various species of Betta. I've seen and worked with data like this tabulated as numbers and percentages, but this graph is spectacular. The information is easy to grasp. 121
Rob Carr @robcarr.bsky.social · 01/08/2024At least that makes sense. Often, it seems they pick the most unrelated image possible. These would have been cooler: 000
Rob Carr @robcarr.bsky.social · 16/07/2024The ad that went with the article about the first lights in the universe: 010
Rob Carr @robcarr.bsky.social · 14/07/2024...the expansion of the universe. He would find examples, and others would demonstrate the objects weren't actually related. Ultimately failing to prove discordant redshifts, he helped demonstrate redshifts were due to recessional velocities. 🧪🔭 2/2 121
Rob Carr @robcarr.bsky.social · 10/07/2024The version sold in stores in the USA has chiral ink but the panels are all hexagons and pentagons. Another ball with a different paint job has both right handed and left handed areas around hexagons and appears symmetrical. I have a headache. I'm not great at 3D visualization. 110
Rob Carr @robcarr.bsky.social · 07/07/2024I'm so old, my brain is fascinated by how much incomplete or wrong information I learned in college. In a great article on placentas and a retrovirus, I saw the following: 291
Rob Carr @robcarr.bsky.social · 27/06/2024Names of groups are fun in English: a murder of crows, a parliament of owls, or a pandemonium of parrots. Scientifically, the names are mostly fun at parties. I can vouch for pandemonium. 010
Rob Carr @robcarr.bsky.social · 26/06/2024That cradle reminds me of the NOAA-N Prime satellite. (It was launched successfully. After repairs.) 251
Rob Carr @robcarr.bsky.social · 10/06/2024No! Trump has had an obsession with sharks, and he recently went on a rant about sharks and batteries. I'm stealing the idea from "Birds aren't real." And, as a parrot owner, it's a go-to joke. I was joking about starting a rumor and don't want to start a rumor! I have a weird sense of humor. 120
Rob Carr @robcarr.bsky.social · 23/09/2023Starlink train again, south of Pittsburgh PA, shot with a handheld Pixel 6A. I invited my wife and neighbors to see. I'm glad they showed up! They're spread out compared to last night, as expected. Nancy counted 22. They disappeared into Earth's shadow. 🧪🔭 🌌🚀 2120
