Mark Rober suggests we focus learning on the success, and ignore failures. Like a toddler learning to walk, who doesn’t remember the falls, and only focuses on the steady progression toward walking. Since I’m a mountain climber, his diagram reminds me about the camps we establish on mountains. The concept is the same.
Mark did a TEDx talk at my alma mater.
Joseph Ducreux was a French painter active in the late 1700’s who should be remembered for self-portraits that were surprisingly informal for the age.
Excellent and fun example of product design iterations meeting new product requirements.
James Bond is an MI6 British secret agent codenamed 007 portrayed in books and film. There wasn’t a reasonable skillset list for him online. So I assembled a list of James Bond skills. Turns out, 007 has many skills.
A list of skills and abilities held by James Bond 007:

On the moon in 1971, Commander David Scott dropped a hammer and a falcon feather to validate Galileo’s theory that without air resistance, objects fall at the same rate due to gravity regardless of mass. Given the negligible lunar atmosphere, there was no drag on the feather, both experienced the same acceleration, and both hit the ground at the same time. NASA did this because they wanted a memorable popular science experiment to do on the Moon, for kids. Very cool to watch.
The Feynman Technique is the best way to learn anything quickly. Devised by a Nobel Prize-winning physicist, it uses the power of teaching for better learning.
There are four steps to the Feynman Learning Technique:
Our experience on earth makes us think that the tides are causing by water following the moon and sun. It turns out the water isn’t chasing the moon and sun. The water stays in the same place as the earth rotates inside the two bulges of water. More on this in the video and on wiki.
This country song was written by GPT-3. The AI was only fed the title of the song, River of Love. The song was performed by singer Anna Vaus. It’s a bit catchy.
We’re fortunate to live in a time when we have two new launch rockets intended to enable crewed launches to Mars.
The two rockets on the left have flown already. The Falcon Heavy flew in 2018 and is currently 32M miles from home traveling at 58K mph. The Saturn V launched the Apollo Missions between 1967-1973.
The two rockets on the right haven’t flown yet. Boeing’s Space Launch System is more expensive and also is not reusable, so it has larger expected price (green bar graph) and $ per kilogram (blue bar graph) characteristics.
