Yesterday, I got email from the relevant companies. The smart glasses I ordered are on the way, actually shipped this time. This marks the end of a long, and quite Ludacris saga. I wondered just how long it really has been, so I took a look in the journal where I keep track of this mission. It’s taken more than five years, almost six. Continue reading Smart glasses, blindness, and shopping→
When a creature dies and becomes buried, sometimes its remains can completely rot and dissolve away, leaving a hollow space within the rock called a mold. If that mold becomes filled with sediment and water, it can harden into rock, becoming a cast. Every so often, the same sort of process can happen within the body of an animal, providing a stone cast of some of its internal arrangements. If that happens within the brain case of a skull, it’s called a brain cast. In 1924, a brain cast found in South Africa caught the attention of British anatomist Raymond Dart. After removing the fossil from the rock with his wife’s knitting needles, he was left with the first few skull fragments of Australopithecus africanus, or “southern ape of Africa,” to be discovered. Continue reading Ep 157: Fossil casts and molds→
Putting together the nodes and handlers is going to be somewhat painful, and slow. It might be a bit more fun, along with giving me a way to test the general concept and implementation, if I implement the handlers to help me do a particular experiment or two. There will be no getting away from days of going through, method by method, bit by bit, but this should be a much more interesting way to get started. Continue reading Making it simple isn’t simple→
The semiprecious stone amber is fossilized tree resin. Sometimes, insects and other small critters are trapped by sticky tree sap, and become encased in amber. Sometimes, microorganisms are found inside amber. Sometimes, they’re yeast that can be revived and used to brew beer.
Here’s an article about the yeast, revived and used to brew beer.
It took a bit of digging, but I found out why the domestic dog fossil found with the remains of the La Brea woman didn’t cause more of a sensation. Using carbon 14 dating, the dog fossil turned out to be around seven-thousand years younger than the fossil of the woman. What is carbon 14 dating, and how does it work? Continue reading Ep 154: Mystery solve, and dating fossils→
The La Brea Woman was found in close association with the remains of a domesticated dog. Her remains have been dated to between 9,000 and 10,000 years ago. Were there dogs that early in North America? How long ago were dogs domesticated? Continue reading Ep 153: Wait… she had a dog?→
Fossils aren’t just remains of animals. Some of them are materials and marks left by organisms as they went about their lives. Called “trace fossils,” they are, instead of a snapshot of death, a snapshot of life.
Here are some articles about the traces humans left on our moon.
In the previous episode we talked about where the oil that formed them came from. Today, we talk about the fossils found in them. Located in the middle of a major city, the La Brea Tar Pits have given up fossils as much as 55-thousand years old.
Here’s a link to a 5-minute video that shows how material is processed from the tarpits, including the large bones and microfossils.
Between technical difficulties, research and recording, I’ve just barely managed to squeeze in some time to do some little chores with the code for my artificial life experiment software. I call my subleq based digital organisms “figures.”
The very next thing is to implement save and restore functions, so I can keep a population and play with it later. I hope to take care of that by the end of the weekend, but no promises.
Once that last little chore is done, I’ll zip up and archive figures0.3. Closing in on the end of this round, my thoughts have been drifting toward the next. Continue reading The next bit→
