All the races of Middle Earth

I enjoyed this introduction to the various races of Middle Earth: https://youtu.be/yZvH4wIKGCM I’m very tempted to try figure out which of Tolkein’s books delve into the history of Middle Earth, before the events of The Hobbit, and Lord of the Rings. Well, I know there are earlier books. I have a little research to work…… Continue reading All the races of Middle Earth

Stand against racism

The wave of violence spreading across the United States is shocking, even as the growing protests are understandable. It boggles my mind that this country, the “land of the free”, is still mired in deeply routed racism, and inequality. Every society has its challenges, certainly. Israel is no different. We have divides of our own.…… Continue reading Stand against racism

How The Hacker Who Saved The Internet Redeemed Himself

I read a fascinating story in Wired about Marcus Hutchins, a hacker who used lessons from years of writing malware to save the Internet from WannaCry, only to come to terms with his past misdeeds at the height of his success.

Enjoying Sam and Liam talking about stuff

I noticed a new(ish) video podcast, AWNP Unplugged, with Critical Role’s Sam Riegel, and Liam O’Brien. It’s terrific, I’m enjoying it. They’re basically just connecting, and chatting about the pandemic, the importance of being connected to each other, and more. https://youtu.be/rOzCBZ5RIqo I’m sitting on one of our couches, blogging random stuff, and enjoying the conversation.…… Continue reading Enjoying Sam and Liam talking about stuff

My favourite science shows

When I sit down to have lunch with our kids, I typically watch my favourite science shows on YouTube. I have three (give or take): PBS Eons;SciShow (along with SciShow Space); andIt’s Okay To Be Smart. I’m pretty sure our kids enjoy the shows, I certainly do. I also realised that there’s some overlap between…… Continue reading My favourite science shows

How Wes Bos built his new site

I’ve followed Wes Bos for a couple years now. I bought several of his courses, and look forward to when I have time to do his Beginner JavaScript — Learn JavaScript from Scratch course. He recently rebuilt his personal site using Gatsby.JS, and published both a post and a video explaining how he did it:…… Continue reading How Wes Bos built his new site

Beautiful Cosmic Disorientation

This Hubble image shows how young, energetic, massive stars illuminate and sculpt their birthplace with powerful winds and searing ultraviolet radiation. In this Hubble portrait, the giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020) are part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, located 163,000 light-years away. The image is nicknamed the “Cosmic Reef,” because it resembles an undersea world. The sparkling centerpiece of NGC 2014 is a grouping of bright, hefty stars, each 10 to 20 times more massive than our Sun. The stars’ ultraviolet radiation heats the surrounding dense gas. The massive stars also unleash fierce winds of charged particles that blast away lower-density gas, forming the bubble-like structures seen on the right. The stars’ powerful stellar winds are pushing gas and dust to the denser  left side of the nebula, where it is piling up, creating a series of dark ridges bathed in starlight. The blue areas in NGC 2014 reveal the glow of oxygen, heated to nearly 20,000 degrees Fahrenheit by the blast of ultraviolet light. The cooler, red gas indicates the presence of hydrogen and nitrogen. By contrast, the seemingly isolated blue nebula at lower left (NGC 2020) has been created by a solitary mammoth star 200,000 times brighter than our Sun. The blue gas  was ejected by the star through a series of eruptive events during which it lost part of its outer envelope of material. The image, taken by Hubble’s Wide Field Camera 3, commemorates the Earth-orbiting observatory’s 30 years in space.

Astrophysicist Katie Mack published a wonderful video titled “Disorientation” just over a year ago that combines cosmic images with her poem of the same name. https://youtu.be/2wT1-bRj9wI I found out about the video while watching another terrific video commemorating the Hubble Telescope’s 30 anniversary on the It’s Ok To Be Smart channel, titled “Fly Through a…… Continue reading Beautiful Cosmic Disorientation
