If I ever invent a new physical actual material or structure, I'm going to call it "syntax error" or "for loop". Then when people complain over the Internet that their syntax error is leaking water, I finally get m

Is the concrete seemingly leaking some white powder? If it is, then you have something to gain from external non permeable layer. Something like this? https://www.rakentaja.fi/keskustelukanava/img/20157/2954

If the bridge is fine, there is no problem. If the bridge is rotten, you have lot fewer victims. You want to do pre-emptive repairs? OK, the bridge ought to be fine. We can then proceed with the destructive testing. You could do the testing

I found such too. But the quality of discussion is sub par even when the original idea was good. Large share of the people who are still active on facebook seem to be types of people who have very few friends and like to shout their ideas i

This would have been perfect situation for some destructive testing. During night time block all traffic. Then drive radio controlled, overloaded trucks over the bridge every six months. If the bridge fails, you just saved human lives. If i

Yes but the steel cable ought to conduct the electricity through the water column into the structure. If there is sufficient resistor in the structure for massive steam explosion, then it's very unlikely that the lightning would ever s

This is not so much a matter of safety factor than redundancy. Safety factor = "it only fails if the bridge is full of heavy trucks and they all are overloaded 2X" Redundancy = "we have 6 stays and any single one can snap and

Umm. Why would you want to parge coat that foundation? Did you try to do that on the outside or the inside? Do you have concrete slab against ground? Cellar? Or is there unused airspace between the floor and the ground?

>It seems to me that putting pre-stressed concrete into tension via its reinforcements is defeating the purpose of having pre-stressed concrete in the first place. I think you are correct there. But it looks like the stays were in separa

Well yeah. But typically that is done by cross bracing. Lighter and more effective against the leverage of the whole bridge. Concrete has low Young's modulus, so you need very wide concrete casing to get the same benefits in stability

Yeah it would be for the short time you manage to do that. "The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals inc

In Finland the building code requires that all office spaces and apartments have a window. It's possible to circumvent this by putting an office into space that was designed as storage or as factory. But you will then usually also lack

Also when Kant said "war protects from despotism" he was living a time when the aristocracy needed majority of the population to take part in war effort. Rich nations have very little reasons to sustain democracy if war is automat

There was a moment in history where clocks were so advanced that they copied needlessly complicated clock mechanisms into pistol firing mechanisms. But that's the only situation I can come up with. Instinct for survival is pretty good

I know something about mechanical engineering and doing away with needlessly tight tolerances is one of the most efficient ways to cut costs. If the cars are designed so that there is some genuine need or benefit from general extra tight to

The wingtip vortices are of course part of the flight, but they are unavoidable side effect. I think I've seen the Kutta-Joukowski visualization too somewhere. If I recall correctly, it was more about visualization/memorization of

"the explanation of lift generation is both inseparable from and dependent on vortex formation" Are you sure about this? There are of course high lift devices and wingtip vortices are unavoidable. But I'm pretty sure you can

I think part of the problem is the event nature of those things. Currently social people seem to be incredibly event oriented. For me the places that form friendships are places where people go out of habit. The living room of my student co

I think it's deeper than that. Lots of religious people don't go to church. Many who go, do it just because of habit or some personal principle of "I'm church going Christian". Churches are not drawing people in, no

Wheel of Time is my go to example of bad fantasy literature. But there is someone disagreeing in here. Maybe it's just sunk cost bias. But anyhow it goes to show how tastes vary.

Interesting how badly I was misunderstood. My point was not that they would be about the same thing. My point is that GDPR is pretty clearly about the rights of the little guy. Lack of net neutrality is clearly about the rights of big busin
