Mirrors—the science of reflectionby Chris Woodford. Last updated: April 13, 2023.Humans spend hours preening themselves in mirrors and, given half the chance, apes, elephants, pigs, and dolphins would do too. Peacocks are a different kettle of fish entirely. Park a shiny blue car near one...
Reflection:Reflection is a characteristic wave as well as of particles. When a moving object or wae encounters a barrier in its path, the direction of motion changes. This is called reflection. Reflection is highly studied in optics. When a ray of light traveling in a straight line from a...
In this comic, Megan sets up two mirrors facing each other, in which reflections bounce back and forth between the mirrors until the mirrors absorb all the light. She then says "Bloody Mary" three times (as in the folklore) before ducking, conjuring an infinite number of spirits who jump ...
The easiest way to explain mirrors is: they don't change left and right, they change forward and backward. What is farther from the mirror appears farther in the mirror. If you look at yourself, your nose and the nose of your reflection are the closest parts of the body together (at l...

Trucks often have signs on their backsides that say, "If you can't see my mirrors, I can't see you." Explain the physics here. What do we call the distortion on a mirror that comes from not using a parabola? What is the color of a mirror? What ...
What is a generative large language model from a technical perspective? A generative LLM is a function. It takes a text string as input (called "prompt" in AI parlance), and returns an array of strings and numbers. Here's what the signature of this function looks like: ...
This distortion made the image look shorter and wider. When I discovered the reason for the distortion I simply loosened the top and bottom clips and the mirror gave a normal reflection. However, I didn’t stop there. I discovered that if I loosened the top and bottom clips a little mor...
While that’s great for any driver of a car with powerful lights, it’s not so safe for drivers of oncoming vehicles. They can find themselves blinded by the brilliant light from the latest systems. Is there anything dazzled drivers can do? And will...
private schools mirror the genetic differences between them, suggesting that socioeconomic status and social mobility are a reflection of differences in genetic dispositions (cf. also Abdellaoui et al.,2018). While this research endeavor is useful for understanding the biological basis of human cognit...
