#3The Pantheon is awesome, but one shouldn't think, "They don't make 'em like they used to."
Almost all structures built 2,000 years ago do not exist today. The ones that do exist are all marvelous feats of engineering because if they weren't, they wouldn't have stuck around for 2,000 years. I guess it's an example of http://en.wikipedia.org/wiki/Survivorship_bias
OK, back to gawking at the Pantheon. It's absolutely stunning that people could build such a dome using 5,000 tons of concrete, no steel, and no power tools.

Thats a great point. All the Model Ts still rolling have incredible longevity but millions of them have been gone for many decades.

Not quite... when digg/reddit get it it'll be cut & pasted onto someone else's blog with ads all around it.

I didn't downvote you, but I guess I just don't get it. Here's the guidelines, seems like this one pretty clearly stands in the on-topic realm of things.
"On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic."

#10It's a dome - domes are in compression - in compression you don't need rebar
