    The crazy thing about this is not just how evolution reverse-engineered what a snake looks like to a bird (or whatever preys on this moth), but also that some birds are born with an image burned into their brains labeled “avoid.” Snakes are such a problem to animals that may also prey on this moth, that a moth was able, over millions of years of evolution, to mimic that image through selective pressure. We’re not seeing here a moth mimicking a snake, we are seeing a moth’s wings resembling the image its prey holds in its brain of what it should identify as its own predator. An image that, itself, is held genetically and passed down from animal to animal, built by its own selective pressure. It’s amazing that this could produce such a clear image that’s immediately recognizable to us.

    I’m pretty sure most adult dogs and cats understand mirrors, they just get creeped out by their own reflection. Take an adult cat, hold it up to a mirror. Watch as it actively avoids looking at itself. My dog stares at me for long periods through a full-length bedroom mirror and even barks and runs to the window when she sees dogs outside through it. Doesn’t really care much about her own reflection.





  • We used to have ramp newbies handle the lavs as a sort-of right of passage. The Lav fluids we called “blue juice.” One day I told a newbie to go to maintenance and get a bucket of “red juice.” He disappeared for an hour. We were wondering where the hell he went about when he showed up looking a bit stressed out, actually carrying a bucket of red fluid of some sort. Apparently he started going around the entire airport’s maintenance shops asking them one by one for red juice, none of them knowing what the hell he was talking about. Instead of asking for clarification over the radio he just kept going. Eventually somebody in a completely different concourse poured some hydraulic fluid in the bucket for him. I was a bit astonished and then had to figure out what the hell I was going to do with a bucket of hydraulic fluid.


  • I think a better term to use would be “fact-based policy.” I believe that even if we intended to rework politics to be more scientific, it would just lead to all the same manipulations and twisting of facts that current politics involves. Don’t like a particular scientific consensus because it interferes with your goals? Hire a bunch of “think-tanks” to publish contradictory papers. Hah, guess what, that’s where we already are.




  • I got one of those once. Tried wasting their time but they weren’t having any of it. Wanted to get straight to the sale?? of this supposed cruise I won. Wanted my credit card number. They thought they had me in the bag, but I had a card up my sleeve. See, a lot of credit cards and credit card systems have these dummy card numbers you can enter to test the system. The POS will recognize the card number as valid and try to run the charge without flagging it as an invalid number. I slowly read a couple of these to them with it coming back denied each time. Kept trying over and over, LOL. “I don’t understand! I have lots of money in that account! Let’s try again, I’ll read it a bit slower this time.” Hahaha




  • I could’ve sworn Jim Beam whiskey was Jim Bean. A friend of mine had a poster of a whiskey bottle on his wall that I stared at every time I was there. He was a minor at the time and didn’t drink, so I always wondered why he had it up. Years later I saw a Jim Beam bottle and had a Mandela moment. The Berenstein Bears and Mandela dying in jail were things I believed, too, but I think the whiskey one is one I haven’t heard from anybody else, yet.
