Welcome to Monday’s News on the March – The week that was in my digital world.
The First Mass Extinction – How Bad Was the great Oxidation Event?
Video presentation by History of the Earth
My early mornings after breakfast are typically consumed by watching a you tube presentation transmitted to my TV. This video about the First Mass Extinction was captivating. I was familiar with the meteor impact which led to the extinction of dinosaurs approximately about 65 million years ago (at the end of the Cretaceous Period), but I had never heard of this extinction event which effectively caused the ionisation (rusting) of the earth 2.5 billion years ago.
This presentation is so impressive with respect to the range of topics covered and quality of imagery. I learnt so much about palaeontology and microbiology. I had to pause the video on a number of occasions to add new vocabulary and terms to my Anki program. I look forward to watching other published videos by the History of the Earth channel.

I always find Sarah’s posts enlightening and entertaining and this true story about the origins of Dr. Jenner’s discovery of “vaccinia” was no exception:
‘On May 14, 1796, Jenner inoculated an eight-year-old with cowpox laced pus. The boy ended up with a short-lived mild fever and some temporary general malaise, but was otherwise fine. Then two months later, Jenner exposed the boy to smallpox, and he developed no symptoms at all.‘ (Read entire article)
When Sam’s topic of conversations delve into the realm of science then my ears prick up. This is where he thrives and his shows are so impactful and immersive. A great listen.
‘In this episode of the podcast, Sam speaks with Jeff Hawkins about the nature of intelligence. They discuss how the neocortex creates models of the world, the role of prediction in sensory-motor experience, cortical columns, reference frames, thought as movement in conceptual space, the future of artificial intelligence, AI risk, the “alignment problem,” the distinction between reason and emotion, the “illusory truth effect,” bad outcomes vs existential risk, and other topics‘.(Listen to podcast)
I can’t get enough of the Bodyweight only exercise sessions presented by Fitness Blender. At the commencement of the Pandemic I made a 6 week work-out program which mainly entail sessions from Fitness Blender videos. I have been following them to a tee and I am thankful for the results not only regarding my cardiovascular improvement but helping me maintain my sanity during the lockdowns.
Today’s featured session which was released this morning is presented by a new instructor (Tasha) to the Fitness Blender team. I look forward to trying it out over the coming days. (Watch video)
