Tonight I am beyond excited to announced my first book: Online Safety for Grade 3/4/5/6 I can officially add #author to my BIO I created it magazine style for kids & parents to read/reference/refresh and share!

The University of Calgary denounces anti-black racism and racism in all forms. We are committed to creating an environment where all are valued and included – on campus and in society as a whole. If you need support, please reach out. We stand with you in these difficult times.

1950: A. Einstein's Letter to Erwin Schrödinger where he talks about the famous Schrödinger's cat thought experiment ✉️ Dear Schrödinger, You are the only contemporary physicist, besides Laue, who sees that one cannot get around the assumption of reality—if only one is honest.

I’m continuously amazed by the outstanding pictures taken and delivered by the NASA Webb Telescope . We are truly seeing space as we’ve NEVER seen it before – and this latest image really captures the majestic blend of the unimaginable physics and cosmic beauty found only in space.

Henry Moseley, the inventor of the modern periodic table, was killed at the age of 27 by a sniper in the Gallipoli battle in 1915. Moseley was a brilliant physicist who worked at the University of Manchester under Ernest Rutherford, the father of nuclear physics. He was

Two, Three or not Two, Three? For those who missed the #aurora, we have two, if not three more #solarstorms headed for Earth! NASA models show impact beginning early August 4 for the first, a drive-by graze for the second late the same day, & the third hitting early on August 5.

Lise Meitner was nominated for the Nobel Prize in Physics and Chemistry 49 times (19 times for Chemistry and 30 times for Physics), but never won. Many people consider this a great injustice, as her colleague Otto Hahn received the Nobel Prize in Chemistry for their joint

There is a fascinating connection between infinity and fractals, which are geometric shapes that have self-similarity at different scales. For example, the Mandelbrot set is a fractal that is defined by a simple formula, but it has an infinitely complex boundary that contains

🌞Sun activity for Nov 18, 2023: Top News 🤩🥳A new region brings on the action 😱One of the new regions has begun to rotate into view on the east limb (edge), and brought sun activity up to moderate levels. Thanks to an M1.2 flare 🧐MORE at EarthSky: bit.ly/sunactivity

Of course we get an X2.8-flare while I'm at #AGU2023. Region 3514 launched a possibly Earth-directed #solarstorm as well. (Waiting for coronagraph imagery to tell for sure.) Expect risk for R3- level #RadioBlackouts & #RadiationStorms to remain high for the next 3 days.

By the way, the Dst index (quick look) hit -412 nT, the first time to go below -400 nT since 20 November 2003. The solar wind data are already messy, making it hard to understand the evolution after the first shock arrival at ~16:30 on 10 May 2024.

Friday night was comparable to storms in 2003 and 1989. They're roughly 1-in-20-years events. But that doesn't necessarily mean the next one won't be for 20 years. It could be next week - they're quasi-random. There's a 5% chance of one happening in any given year. (1/3)

National Indigenous Peoples Day is an opportunity to reflect on our shared history and work towards reconciliation. Today, we celebrate the rich and diverse cultures, traditions, and contributions of First Nations peoples in Canada. 1/2

Resilience, strength, and pride. Happy National Indigenous Peoples Day.

On this day in 1986, Canadian author Robert Munsch released his book Love You Forever. One of the most successful children's books ever written, it is beloved by generations of Canadians and others worldwide. Let's learn more about it (and try not to cry)! 🧵1/10

Indeed a #solarstorm is launching now. The dimming regions reveal where the storm is tearing off the Sun. This one is likely Earth-directed. Waiting for coronagraph imagery to inform prediction models. Expecting late October 3 to early October 4 as arrival window, but we'll see.

Show me on Thursday to learn from Ross about preparing to go to Mars. In person or streaming!
