Three Tidbit Stories

Physics.

3 random tidbit stories in about 3 minutes.

1.

Physics FAQ.

While Charles Forster commercialized the first wood toothpick in 1869, the story of the toothpick stretches far back into the Stone Age, long before modern civilization. The earliest use of toothpicks can be traced to Homo habilis, an ancient human ancestor who lived around 2.3 million years ago. By about 1.84 million years ago, Homo habilis began using simple toothpicks—likely small sticks—leaving behind telltale grooves in their fossilized teeth. This practice of using readily available things like twigs, feathers, and bones has been a human endeavor for millions of years. 

What makes this discovery fascinating is the timeline. Homo habilis had already been shaping stone tools for nearly a million years, developing tools for tasks like cutting meat and plants. This tool use reflected increasing cognitive abilities. Over the next half-million years, this brain evolution fueled cultural innovations like using toothpicks. This dynamic between biological evolution and cultural advancements—where each fed into the other—shows just how adaptive and resourceful early humans were, even when it came to something as simple as cleaning their teeth!

Physics Quote.

Stress is sometimes what happens to us. But too frequently, it’s about what our minds think is happening, and that’s a problem. The problem is that too frequently you are far more hurt by your thoughts of what happened, and not by what actually happened. For example, most of us too frequently overreact when someone points out a flaw in something we did. The criticism may contain one useful fact, but our minds can turn it into a judgment about our entire worth. We replay it, imagine worse outcomes, and focus on everything that might go wrong. You cannot always choose the first thought that enters your mind, but most of the time, you can choose which thought gets your attention next. That is the useful idea behind this quote.

William James wrote extensively about attention. In The Principles of Psychology in 1890, he described attention as selecting one thing from several. In other words, your mind cannot focus equally on everything at once. Think about how craze it would be if every sound all day long got equal attention. That would drive you crazy! The same goes for your internal thoughts. You get to choose.

Stress, angst. That anxiety is a cue to you that you need to slow down and look more carefully at what you are doing. Not every anxiety is an ethical problem, but when the tension comes from a difficult choice or uncertainty, pause. Listen to the guidance around you. Clarify what is actually your responsibility. Think through your intent, likely results, and who may be affected. Anxiety is your mind telling you that the easy answer is not enough.

You may not control every thought that appears, but you can get better at deciding which ones deserve your time.

Physics Story.

520 Million BCE
Simple Brains; Proto-Short-Term Memory; Simple Sentience.

From no sentience or presentience to solidly “Simple Sentience,” early fish during this time represent our ancestral beings that started to suffer and feel the dichotomy of pleasure and pain.

Haikouichthys (circa 520 Million Years Ago): Dwelling in the ancient seas of the Cambrian period, Haikouichthys is among the earliest forms of vertebrate life, showcasing fundamental advancements in the complexity of the nervous system. Unlike its precursors in the Ediacaran period, which exhibited only the most rudimentary forms of interaction with their environment, Haikouichthys possessed a more developed nervous system, allowing for more nuanced responses to stimuli. This development marks a significant evolutionary leap towards the ability to experience basic forms of what we might consider suffering and pleasure. Its existence underscores a pivotal transition in the evolution of life, bridging the gap between the simplicity of early multicellular organisms and the complexity required for the nuanced experiences of sentience.
