Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.

5. Only recent news is allowed.


Posts must be news from the most recent 30 days.


6. All posts must be news articles.


No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.


7. No duplicate posts.


If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.


8. Misinformation is prohibited.


Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.


9. No link shorteners or news aggregators.


All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.


10. Don't copy entire article in your post body


For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

In the quest to build better for the future, some are looking for answers in the long-ago past.

Ancient builders across the world created structures that are still standing today, thousands of years later — from Roman engineers who poured thick concrete sea barriers, to Maya masons who crafted plaster sculptures to their gods, to Chinese builders who raised walls against invaders.

Yet scores of more recent structures are already staring down their expiration dates: The concrete that makes up much of our modern world has a lifespan of around 50 to 100 years.

Also don't forget about survivorship bias. We don't know how many percent of their buildings are still standing. Probably only the really really good build ones. Also never forget, any idiot can build a bridge that stands. It takes an engineer to built one that barely stands. And that is often what we are doing today. Making our stuff "good enough" as otherwise it wouldn't be economic feasible in the short or midterm. I am still curious how good it would be if we would instead aim for the long-term though..

More ancient buildings have fallen than are standing I'd imagine but I don't agree that just anyone can built a bridge. I'm not an engineer so I feel really inadequate making an opinion though. I agree 100% it would be very interesting to see how building practices would change if the goal were to construct buildings for longevity. There are lots of considerations though: weather, earthquakes, natural disasters, etc.

Another user posted a practical engineering video that I hadn't seen yet and I heard your exact phrase about anyone building a bridge that stands so mea culpa i didn't know any better.

Hey, no need to apologize for anything 🙃 yeah, that phrase is a quote ire st least kind of a meme.

I try to own up to my mistakes.
