A small home demo of an early pulse pump type! Fascinating work, I'm glad to see this involved in anthropology
Why the Tacoma Narrows Bridge Collapsed
Wind can be one of the most critical and complicated loads on civil structures. The case of the Tacoma Narrows bridge is a well-known cautionary tale that’s discussed in engineering and physics classrooms across the world. Both resonance from vortex shedding and aeroelastic flutter contributed to the failure. When you push the envelope, you have to be vigilant because things that didn’t matter before start to become important (e.g. wind loads on lighter structures). Unanticipated challenges are a cost of innovation and that’s something that we can all keep in mind.

favorite trope ever is the exaggerated fucking. "what the hell why can't I stop thinking about them" type thing (think dipper pines "its not like I lie awake THINKING about her" ... "uh oh")
scout is reading a magazine. all of the scantily clad women morph cartoonishly into pinups of one mister mundy. engie is drafting a battle plan. when did he start drawing a candid of spy???? thats not even his area of expertise.
its just too funny

An overview of the 2022 Montana flooding and what's next for Yellowstone National Park.
Errata: At 8:53, the bridge shown in the photo is the Gardner River Bridge, not the Yellowstone River Bridge slated for replacement.
In June of 2022, many tourists and residents of the Yellowstone National Park area found themselves at ground zero of a natural disaster. Torrential rainfall in Wyoming and Montana brought widespread flooding to the streams and rivers that flow through this treasured landscape and beyond. How will the National Park Service Rebuild? Hasty engineering of large infrastructure can be extremely damaging to natural systems like those in Yellowstone, and you don’t want to invest millions of dollars into repairs that might be subject to similar flooding in the future. After all, we build parks (and roads to parks) to get closer to the natural environment and all its wildness, and there’s almost nothing more natural or wild than a flood.
Some unexpected issues for engineers who design subsurface structures...
Worksafe BC video: https://youtu.be/kluzvEPuAug
Next time you see a dam, retaining wall, caisson, or any other subsurface construction, there’s a good chance that engineers have had to consider how groundwater will affect the stability. Even though you’d never know they’re there, some combination of drains and cutoffs were probably installed to keep the structure (and the people around it) safe and sound.

How Does Permeable Pavement Work?
Some pavement can let water in and keep everything else out.
Cities represent a remarkable transformation of the landscape from natural to human-made. One of the most significant changes to the landscape that comes with urbanization is impervious cover. That's anything that prevents rain from soaking into the subsurface: buildings, sidewalks, driveways, and the biggest culprits - streets and parking lots. Impervious cover is a big issue. When you pave paradise to put up a parking lot, you cause a pretty significant disruption to some really important natural processes in a watershed. But, not all cover has to be impervious.
