  • The explosive often wasn’t enough to damage a full steam engine. What it could do was terrorise the crew and guards. The ones I heard about didn’t have a detonator. The guards had a habit of burning dead rats to get rid of them. Often in the fireplace of the guard shack. The goal was to throw fire and hot metal into the guards gathered around to stay warm.

    The other advantage of a rat is that most guards wouldn’t look too closely at it. Someone with lumps of coal might have them looked at, if they are caught. They are stealing coal, after all. Someone hunting rats, for food, the other hand? Poor and disgusting, get out of here and take the damn rats! You have an excuse to be there (other than sabotage) and nothing they will want back.



  • Most of the problem with lasers come from focusing them. The eye is incredibly good at it. This means even a small laser pen can reach MW/m^2 ranges by the time it hits the retina.

    IR is a different story (at longer wavelengths). Without the ability to see it, our eye will not attempt to focus on it. Also, our eyes lenses are not particularly transparent to it. 3rd, the ultra short pulses mean that there is no time to focus.

    As for the mosquito, the laser is tuned to a frequency that is strongly absorbed by their wings. Given their size and how delicate their wings are, a tiny amount of energy can cause significant damage. Conversely, the same energy on our eye will just cause a slight amount of heating. The bulk mass of the eye will absorb this fine, with no damage





  • I suspect it’s a selection effect. Amazon is a pain in the arse to work for. Decent drivers are in demand. This makes it easy for good drivers to jump ship to other companies. This leaves the inexperienced or just stupid drivers left to deal with the BS.

    If you’ve not driven a van before, they are intimidating to maneuver, at first. It’s takes time and skill to spin them on a dime, and slot them in, with awareness of how much space you are leaving. Novice drivers simply lack that skill.






  • Just noticed a slight typo, fixed now. Also, at that point, most of the tests are useless and distinguishing the differences.

    It’s also quite weird. To me, it’s completely normal. It actually took significant mental training to match up with how others think. I knew I was quick, but not that quick.

    Unfortunately, it’s also a coping mechanism (adhd + autism + a few more quirks). My brain handles certain tasks abnormally. E.g. I can’t read emotions intuitively. I have to brute force it with general intelligence methods. I also have memory issues, again, compensated for with brute calculations.

    It’s a bit like being terrified of riding vehicles. You learn to cope. You then get slightly surprised when people complain how hard marathons are. You jog the 15 miles to work and back everyday! It’s not that hard. You develop the skills because you need them.

    Intelligence (particularly IQ) is also only a subset of being smart. I know people far smarter than me. Their IQ might not be at the same level, but they can leverage it massively more than I can. I’m a hot rod, amazing on a 1 mile track, crap on normal roads.


    1. Yes, I even have the paperwork to back that up. (99.7 percentile)

    2. No, I’m also a classic example of the difference between intelligent and smart. I’m a 1000hp engine in a reliant Robin van. Immense power, but limited in my ability to apply it to useful tasks.

    3. I’m the main character in my story. I know, logically, that I’m just another speck of humanity to others, but my ego can’t function in that state, so it doesn’t.

    Edit: apparent an extra 9 slipped in.

    You wouldn’t laugh at a fat guy going to the gym.

    The lady is cycling to work each morning. The initial impetus might have been bad, but she’s doing a lot better than most people. Once she gets into the habit of cycling, she’s a lot less likely to stop than if she’s laughed at for it. It might also help her realise the truck isn’t worth the hassle.
