Classic Chinese tomato egg dish (mostly) following a recipe my brother recommended on YouTube. I didn't rub the tomatoes in flour and I skipped the green pepper. Served on brown basmati and wild rice.

Dr. Tosiron Adegbija of the University of Arizona presented earlier this month on "Right-Sizing Intelligence: Hardware, Software, and the Sustainable Future of AI" for the HardScience SF Writers Readers Artists Zoom Group.

Thanks to everyone who came out yesterday evening (in person and in spirit) for the informal Ottawa celebration of the life of Jean-Louis Trudel. It gave me comfort to know that Jean-Louis will live on in the hearts and memories of all the people he touched over the course of his accomplished life.

Gladys West, one of the pioneering Hidden Figures of the early U.S. space program, has died at the age of 95. She did fundamental work on the development of Earth gravitational models that are important for missions like GPS and radar which require the orbits of the satellites to be precisely known.

My brother Ken Choi is a co-author on a paper in @cjemonline.bsky.social on the demographic and socioeconomic characteristics of emergency medicine residents in Canada. It is the first DEIIA (diversity, equity, inclusion, indigeneity, accessibility) study of Canadian emergency medicine residents.

#EccentricOrbits by John Bloom about the rise, fall, and rise of the #Iridium satellite constellation is my absolute favourite space business book. So I was positively giddy when I recently picked up a near pristine hardcover at the local public library's used bookstore for the princely sum of $2.

I am so proud of my sister Dr. Margaret Choi, not only for the recognition from BC Children's Hospital on this #NationalPediatricianDay but for her years of tireless dedication both within and beyond the walls of the hospital in providing care to the smallest and most vulnerable of patients.

Congratulations to Dr. Peter Annan on his appointment to the Order of Canada. Peter is an internationally recognised expert in the field of ground penetrating radar. During my early career I had the pleasure of working with Peter on proposals for GPR instruments for lunar and planetary exploration.

There is a disturbance in the Force this New Year's Day as I mourn the recent death of my friend Tom Srsa. May he live in the memories of his family and friends, in his children Adrian, Michael and Maya, and in the students whose lives he enriched over a long teaching career. tinyurl.com/2t3h4t2h
