  • It seems maybe you’re actually misunderstanding. As I mentioned above, both you and the other commenter are certainly correct that the surrounding atmosphere (water in your case) exerts force on the objects as they fall, with varying effects depending on object density. However, if you take two objects that have vastly more density than the water (let’s say a big tungsten rod and another tungsten rod that has a hollow core), they will drop at approximately the same rate in the water even if their density vs each other varies. The greater the difference of their density versus the density of the medium, the less the effect of the medium. Is there still technically an effect? Sure, but that effect is negligible from a human perceptual perspective.








  • The only videogame my dad has ever gotten into (other than Pong) was NFS II SE. He wouldn’t race, he just liked driving around at 35 MPH and looking at the scenery. He enjoyed this so much he bought a wheel and pedals for it. I loved this game as a kid, and the fact that I could play it with a wheel. The song “Headless Horse” off the soundtrack is pure 90s cool as well.






  • Technically no, this photographer is putting flowers under a blacklight and photographing them, resulting in a picture of basically what a human would see IRL in that scenario (aside from things like contrast/exposure variances, etc). It’s not really the same as what UV sensing animals would see. These photos are of regions of the flower converting UV light into human-visible visible light (via fluorescence, same thing as a blacklight poster). UV sensing animals are seeing actual ultraviolet being reflected by the flower as well as visible light, so it’s not the same thing.
