“People often quote 22 dB/cm/MHz attenuation of ultrasound. Decibels are a logarithmic scale, so with 1.4 cm of roundtrip skull distance, and typical fUSI frequencies of 10 MHz, this would be 14 orders of magnitude of attenuation!

The best tool for the job is, I’d argue, the one that does the job most reliably for the least amount of money. When you consider how little expertise or data you need to use openai offerings, I’d be surprised if sentiment analysis using cl

In a lecture I saw 10 years ago, Freeman Dyson advocated for teaching children to genetically engineer plants. He thought without the playful urge of children, we’d never be able to create “warm blooded” plants capable of surviving on aster

Many historical mystical experiences are triggered by asceticism. Restricting food, water, social contact, sex, oxygen — engagement in extreme darkness, extreme cold, fatigue, meditation. In short, one could argue, there is no such thing as

One reason why psychologists like to operationalize concepts is to make them measurable. Take a look at the way mystical experiences are measured—it’s a great way to get clarity on what mystical experiences are. https://psycholog

Is there any evidence supporting the hypothesis that Pythagoras was invented?

And if someone thinks this guy is wrong, then they can write an article with their opposing evidence and interpretations. And that’s how we do science.

Haha, sources for which fact? I wrote a paper that deals with Pythagoras here. https://www.sciencedirect.com/science/article/pii/S240587262...

It’s the best disease, I tell my kids. Btw, long term heart issues are more positive for those prescribed amphetamines than those with adhd but unprescribed. Phew. But we are different.

Well, technically he founded “philosophy” more than a religion. Polytheism was really old, of course. But intellectual polytheism (which requires an esoteric treatment of gods as metaphors) was basically new and then lasted for 1000 years.

Nearly 2 years ago I bet a roboticist $10 that we’d have “sci-fi” robots in 2 years. Now, we didn’t set good criteria for the bet (it was late at night). However, my personal criteria for “scifi” are twofold: 1. Robots that are able to make

This level of skepticism flies in the face of references to Pythagoras across multiple contemporary authors. Keep in mind that it is damn hard to prove something in the 6th century BC with the same level of evidence as today. But Heraclitus

Completely agree. One can be skeptical, but the actual man is likely greater than the legend. I own a coin designed by Pythagoras. Well, it’s from 510 BC Croton, features the tripod from Delphi, and has little snakes at the bottom. Also 10

I wonder whether the mental inhibition of the voices ends up strengthening them. If you drop the conscious inhibition, they fade through other means.

Indulgences also paid for the art of the renaissance. It was because pope Leo X was so into art that he stepped up indulgences, causing Luther to protest. So renaissance art has more blood..?
