Examples of optical illusions that deceive about size

The thing that astounds me is that you find the CD idea more convincing despite a complete lack of evidence.

Nice to see your posts have left the moderation queue. You don't know that. It looks the same as a small black object close to you, the position in the image simply creates an optical illusion that makes you think it's sitting on the path when it's not. Consider: If there had really been a big...

choosing metrics reflects your idea of what the problem is if the authors doesn't make it clear why they single these metrics out, they're not transparent about their stance towards the problem if you read their study on city traffic (or even the summary) and can't answer the question why they...

the farm animal proponents need to explain how the animal can break at least two laws of physics, 1. casting no shadow on the ground, and 2. being invisible to the human observer while showing up on camera.

I believe what you think of as the shadow is actually the underside of an almost flat part, like the seat of a chair.

Looking at the full pictures, I believe we'd see more of a shadow if that object was sitting on the path—I don't think the terrain can hide it completely. The absence of ground shadow points to it being in mid-air, in my opinion.

The fact that the object only shows up in the one picture, and that you didn't see it yourself in the park, makes me think it is small and close (and in mid-air). Possibly a leaf that was falling off the tree that you were standing under, possibly with an insect in it (they sometimes form the...

First off, image forensics are commonly used to detect photo manipulations. If you know you didn't manipulate your picture, it won't tell you anything much. I am trying to figure out the shadows in this one. From the stripes, it looks like it ought to be in the shade of a tree, but then it'd...

these 3 points don't have anything to do with NIST's objectives, they're simply @Henkka's personal "I'd like to see". Which is why I've called his post a derail of the topic (in #40).

compare Percentage of English speakers by country (2014). The graphic is sourced to Wikipedia, but I couldn't find it there. And obviously population density plays a role as well, which explains Australia and Canada somewhat.

The excuse would be that this was a talk show and not a topic he'd have been able to prepare beforehand—mistakes will be made, and this was one. I'm sure he's aware as a physicist that fusion=clean, fission=dirty, but not aware (because he's not a weapons export) that a fusion bomb needs...

He has been told, at https://www.metabunk.org/threads/wtc-7-collapse-easy-to-predict-hard-to-explain.12496/#post-272974 . Obviously he might've forgotten.

I believe @captancourgette was referring to the other countries in his list, specifically Nigeria, Kenya and Uganda, where English is one of the official languages.

I'm assuming that if it followed all known physics, we'd have found it by now.

Dark matter/dark energy don't follow the known laws of physics, although their effects can be described in terms of known physics—that's how we know they exist. The "either all of physics, or none of it" approach is not fruitful for discovery.

Who would pay for it? Who else would want to see it? Why doesn't Kostack's simulation do what you want? Why are you derailing the topic?
