  • The classic “five senses” works well enough for the basic understanding of how we interact with the world, but doesn’t actually hold up under much scrutiny. You can apparently get up to 12 depending on how you want to define things.

    The idea of five classical senses dates back at least to Aristotle, himself a rather classy guy. In De Anima (Of the Soul) he argues that, for every sense, there is a sense organ.

    Let’s tweak Aristotle’s definition of what a sense is just a bit. Instead of a sense organ, each separate sense really only requires a different kind of sensory receptor. In the skin alone, there are at least four different kinds of sensory receptors: those for touch, temperature, pain, and proprioception (or body awareness).







  • Some states have required that job postings must include a pay range for the job in question, so since the company won’t post the range, they refuse to hire in those states.

    Not a lawyer, but this sounds shady as hell. Also probably not illegal, since they are specifically avoiding the places where it IS illegal.

    There are all sorts of (backwards, ignorant) reasons why they may not want to disclose the pay rate, but it immediately puts me into the worst assumption that it’s some sort of bait and switch scam. They can “unofficially” tell you what some people make, or what the mean earnings are (inflated due to a few high earners), to get you in the door, but most people won’t touch that. Like MLM job where you’re responsible for getting your own business. Or where you get a minimum wage base salary and a few people get huge commissions, but most barely scrape by.


  • I’ll admit, I only made it through part B. This is where you think that because you are the only one to have this thought, it must be a simulation. It doesn’t actually mean that, but that’s irrelevant anyway because you aren’t: The Anthropic Principle (https://en.wikipedia.org/wiki/Anthropic_principle) is a well-known part of cosmology and philosophy.

    Living at only one point in time doesn’t have any greater meaning. Flip this the other way: imagine you have a minimal amount of hand-eye coordination, and you can hit a dart board, but not enough to hit a specific number. So you throw a dart and hit a 3. The chances of that are 1/20, and the chances you hit the very specific spot on that 3 is astronomically smaller. That doesn’t mean it’s special, it’s just where you hit.

    Your observations and experiences aren’t meaningful because they’re planned, they’re meaningful because they’re yours, and you couldn’t have them at any other time.





  • There are different answers depending on the end goal.

    Mere survival: Isolated human populations have been bottlenecked to as few as a few hundred individuals and survived, IIRC.

    A quick search says biologists like to see 25+ breeding pairs to maintain an animal species (if I’m reading that correctly). So 50-100 seems like pretty close to the minimum.

    Long-term colony building with full genetic diversity needs a lot more: At least one estimate is as high as 40,000 people. The high number is for Earth-like diversity in the population, and with no need for any overarching breeding program, so it’s really kind of an outlier scenario. That 40k figure can be pared down significantly if you have strict protocols, or accept some loss of diversity.

    So anywhere from 50 people to 40,000 people, but the end result will look wildly different at the extremes.
