a simple "Try and keep a constant distance from my neighbors" algorithm

Probably the same algorithm birds use when they fly into a tree -- "try to keep away from branches". They just do it ten or one hundred times faster than we can, so it be black magic to us. A tight loop, run with highly priority, and featuring a few key bits of inline code.

(1) the math doesn't break down, the theory does. If the math broke down as well, we wouldn't know the theory had broken down.

(2) an analogous discontinuity of the Earth would be "falling off the edge of the Earth", as some used to believe. That broken theory got changed centuries ago.

(3) I know of no one that thinks of subatomic particles as points but I do know of theories whose flaw comes from them being based on point particles.

I could. But then safety goggles don't work well on top of glasses -- fog up, push glasses into face, etc.

I feel old when it comes to worrying about wearing safety glasses vs regular glasses -- as in, I'm not worried about it. Just as I rode my bike(s) for years before I had to wear a helmet.

Today we are super worried about, for example, bike helmets, safety goggles & hard hats. But then we buy ourselves seasons tickets to NFL football and lose our hearing instead. Has anyone ever seen anyone wearing ear protection at a sporting event?

By the way, still no helmet required when one goes to a public ice skating session. That ice is like concrete and, last I checked, falling is an every minute thing for some people.

Then there's tennis. I ruined my knees playing tennis. Chasing after every ball stretched everything in my knees. Decades later I met others who had the same experience. But how many people wear knee supports playing tennis? Only those injured already.

Safety regulations cause us to become fanatical...about some things. While remaining blissfully ignorant of other potential threats.

I agree with your points, with the exception that I especially like wearing my glasses outside. Walking down an overgrown trail, I have less concern that a bush will whip into my eye.

Also, whenever I am using a hammer or skill saw, I have more eye protection that someone not wearing glasses. No, they are not a full replacement, but then again I am only referring to "around the home" situations.

though your Wikipedia reference doesn't really support your claim

Well, since you were the one to say that freight trains had priority over passenger trains, how about you support your claim.

but in much of Europe, the passenger trains do have right of way, even if they're running late

And in Canada (where I worked for CP Rail some decades back). It surprised me that the U.S. operated differently.

In the US, slow cargo trains have right-of-way, slowing down passenger trains.

Not quite. Passenger trains have priority, and only lose it when they run late and even then, it is not that freight has priority over passenger service but that it does not have to yield to passenger trains. It would be more accurate to say it becomes "first come, first served". Kind of like if you reserve a table, they hold it for you for a few minutes after the time you set, then it becomes available to all.
