> I'm struggling to see how somebody on their own could come up with a non-trivial scientific result that was meaningful in any way. Richard Feynman at 67, partaking in an inquiry into the space shuttle challenger disaster, dunked some pieces of rubber, taken from a model of the challenger, in ice cold water and observed that they lacked springiness. The full story is fascinating. Other simple, non-rigorous experimen…

Um, feynman was a professional physicist who worked on billion dollar projects. For the o-ring, he (and NASA, and Morton Thiokol already knew the behavior of o-rings in cold weather, and it was engineering, not science. He would call what wolverine above is describing as similar to cargo cult science.

You’ve stated that “the majority of real science is dull work, such as requesting money, writing presentations to convince people you're right, and debugging experiments.” (I agree on the third point)

But regarding the first two as being “real science” and claiming authority on where Feynman’s comments about cargo cult science would be directed? You must acknowledge the hypocritical stance you’ve taken.

You’ve co-mingled the initial statements that Wolverine made with your disdain for people who write hackaday articles and are written up in the media. You’ve introduced that notion and then derided human curiosity and informal experiments as being “not science” or being “engineering” (and somehow mutually exclusive from science) or “citizen science”.

All of these different ways to deride something that you introduced to the conversation - the perils of bad science journalism.

You’ve stated

“ I've worked in citizen science and I have even done some exciting stuff in my garage, which attracted the world's leading researcher in my area of interest. The first thing I'd need to do with my tech is to bring it to his lab and…”

That’s where you’ve made your off-by-one error. You’ve said “the first thing I’d need to do” when you meant “the next thing I’d need to do” — as if the Real Science had not already begun.

“Real Science” starts a lot sooner than you claim.

I wonder if spiders have fights over who gets to build their net next to that big, bright lantern. Those must be prime real estate for them.

It'a a purely legal form of combat. Lawsuits and contract disputes.

I suppose with up to eight eyes, you can get a lot reading done.

This actually squares with the study, no? I mean, when they are inside - and it's my experience as well - they might take the window as the main source of light and think that's the sky, so they start to fly in circles.

The observable effect is true, but I don't think it squares. Circles below the ceiling in the middle of the room aren't perpendicular to the window as a light source. I see this mostly with one particular type of fly that just loves going around light fixtures, maybe they're sensitive to the EM spectrum rather than visible light?

I think flies might use both sky and gravity for navigation and when sky is not up it messes with them and results in circles.

I don't think those circles are exactly perpendicular to the vertical direction. I think most of them are skewed.
