    It appears to be a 1970s bike (I would take a stab at a Yamaha LT3) and by that period shutter speeds of 1/500 or 1/1000 were readily available amongst better quality cameras. That would be plenty to get a clear shot of the spokes on what would be a relatively slow moving bike (I would assume <40km/h, likely noticeably less). I’ve got several 50s era cameras that have 1/500 top speeds, so even if the bike was new at the time of the photo it didn’t require a new camera to take the shot.



  • The watermark is noticeably more readable in the Facebook image I linked though, and it does say photography (even there it is somewhat blurred though, so assuming it was actually clear in the original source that copy is a few recompressions along the chain).

    The dates of the other sources however are what really convinces me it’s not AI. After all, who was doing good quality photorealistic AI image generation in 2021?



  • Seems legit enough to me. The next rack of tomatoes would only be ~2m away after all given the gaps between rows aren’t going to be massive. Pretty sure the sharpness issues are primarily from repeated JPEG recompression data loss - you can find a better quality version of the image by searching ‘carmine spina tomatoes’ which both looks less compressed in the far ground and dates from at least 2022 (so before mass popularity of AI generation).












  • A trebuchet primarily transforms downward motion (of the counterweight) into forward motion, so it would actually work - the trebuchet doesn’t push the ship back as much as it pushes its load forward. This is particularly so if your trebuchet has wheels and you have room on your ship to accommodate it rocking back and forth when firing.

    Edit: Thinking about it this technique would work even with something that does impart equal backwards force on the ship when firing a projectile, because there is considerably more force involved in winching the ship towards the anchor than what is involved in actually moving the anchor. You aren’t pulling against the inertia of a free floating anchor after all, you’re pulling against the ground the anchor has hooked into.


  • I never had a problem with walking around cows as a kid and I did it pretty often. Visitors would get spooked occasionally because cows love to follow you and see what you’re up to, but I never got chased or anything. That was beef cattle country though so these cows were mainly cows (female) and steers (castrated males). I’ve heard that some bulls could be territorial however so your mileage may vary if one is around - the couple I’ve walked around were fine but your chances of issues are higher with them.
