Dutch Water Works

The Netherlands have a long history of extraordinary public works when it comes to water management. With much of the country’s land lying at or below sea level, massive civil engineering infrastructure is a necessity. In this Practical Engineering video, Grady takes us on a tour of Dutch water works, from the centuries-old techniques that allowed farmers to claim arable land from marshes to the unbelievably massive structures that protect the Dutch coastline from flooding and storm surges.

For the Dutch, these projects, expensive as they are to build and maintain, are cheaper than the cost of inaction, as numerous devastating floods of the past have taught them. Although the goals are often the same — shortening the coastline, protecting land and people — the techniques are constantly evolving, especially as ecological needs of non-human species are taken into account.

Reinforced concrete shows that people break engineering. The original promises about the lifespan of reinforced concrete assumed that the rebar was not allowed to oxidize before it was enclosed in concrete, but construction workers never got the memo about storing rebar somewhere dry and when you add salt water from road salt garages rot from the inside out. cbc.ca/news/canada/ottawa/publ #civilEngineering #errorBetweenKeyboardAndChair

The Best of FYFD 2024

Welcome to another year and another look back at FYFD’s most popular posts. (You can find previous editions, too, for 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, and 2014. Whew, that’s a lot!) Here are some of 2024’s most popular topics:

  • The Taum Sauk Dam Failure and Its Legacy
  • Stretching Ant Rafts
  • Gigapixel Supernova
  • Feynman’s Sprinkler Solved
  • Calming the Waves
  • “Dew Point” Deposits Droplets
  • Drying Unaffected by Humidity
  • Trapped in a Taylor Column
  • Exciting a Flame in a Trough
  • Remembering Rivers Past
  • A Comet’s Tail
  • Light Pillars
  • Liquid Metal Printing
  • The Miscible Faraday Instability
  • A Triangular Prominence

This year’s topics are a good mix: fundamental research, civil engineering applications, geophysics, astrophysics, art, and one good old-fashioned brain teaser. Interested in what 2025 will hold? There are lots of ways to follow along so that you don’t miss a post.

And if you enjoy FYFD, please remember that it’s a reader-supported website. I don’t run ads, and it’s been years since my last sponsored post. You can help support the site by becoming a patronbuying some merch, or simply by sharing on social media. And if you find yourself struggling to remember to check the website, remember you can get FYFD in your inbox every two weeks with our newsletter. Happy New Year!

William & Mary: LiDAR project maps world’s largest earthen enclosure. “Sungbo’s Eredo in Nigeria is a system of walls and ditches that is considered the largest earthen enclosure in the world. Using LiDAR, or ‘light detection and ranging’ technology, a team of researchers from William & Mary just completed its work to measure the monument, collecting data over a five-year period.”

Earlier this month we announced the pre-alpha release of our new software CatColab 0.1: Hummingbird. The aim is to enable truly collaborative modelling, in a way that is accessible to parties of different technical capabilities and with different schema for understanding how a model "should" work, whilst remaining mathematically formal enough to allow for techniques from computer science to enable numerical simulations, structured version control, and more. A key focus is how this can be used by multi-domain teams, enabling all stakeholders to understand their agreements (and disagreements) clearly — to quote from another recent blog post (topos.site/blog/2024-10-11-non):

[...] we want to build technology that permits collaboration between domain experts of many different domains, not merely those who trade in concepts which are crystallized enough to be faithfully captured by definitions of the sort found in mathematics. Thus, acknowledgement of formal (but not logical) concepts is important for those who wish to work on the border of mathematics and application (particularly in domains studied by social sciences and the humanities).

You can read more, as well as watch some demo videos, and even play around with it yourself, in the blog post: topos.site/blog/2024-10-02-int

This is the blue bridge in Freiburg. Built in 1886 it was originally used by cars and trams. In 1961 however the tram tracks were removed and in 1996 the bridge was closed to motor traffic. It since has been dedicated to pedestrians and cyclists only. The bridge is a key piece in the local cycling network, connecting the growing west of Freiburg with the city center. A daily average of 10,000 bicycles cross the bridge. But it is not just a piece of infrastructure. Many people come together on the steps and arches to have a drink or watch the sunset.

ผมไม่ได้มีงานวิจิยที่ส่งเข้างานนี้แต่ด้วยความที่มันอยู่ที่พิตต์สเบิร์กก็อาจจะมีไปแวะเจอคนรู้จักที่ไป ถ้าใครจะมางานนี้ก็มาเจอกันได้ครับ

: She believed she could, so she did.

Congratulations to our Founder and Executive Director, Jasmine M. Jackson, who completed her year-long #NCEPFP (Education Policy Fellowship Program) and delved into education policy at the state (North Carolina) and federal levels!

We can't wait to use the information our founder learned through her fellowship to better service our future accelerators with #digitalliteracy and #cybersecurityeducation by exposing and having them thrive in the technological age.
