    Bridge Model
AI Thread Summary
The discussion centers around a 10,000 toothpick model of a bridge created as a school project. The bridge weighs 1306.15 grams, spans 1.16 meters, and successfully held a 70-pound weight without breaking. The builder faced challenges with the arc shape but found an effective solution using a ruler to create the design. The construction process took two months, and wood glue was chosen for its durability over hot glue. Overall, the project showcases impressive engineering skills and creativity.

I hope that you enjoy my new video! Here is the description:
This is "10,000 Toothpick Model of a Bridge"

Specs

Weight: 1306.15 g
Height: 0.149 m
Length: 1.38 m
Span: 1.16 m
Width Of Foot: 0.195 m
Width Of Roadbed: 0.0615 mI built it in the 8th grade. A project in math class was to build a 1,000 toothpick bridge over a one foot span. My group's bridge held 54 pounds before breaking. The current bridge was planned to span to span 5ft. It fell a little short, but the actual span can be found above in the specs. I had my little sister, who was 70 pounds at the time, stand on the bridge, and it held her weight. She was 70 pounds. I do not want to test it any further! I do not care if it could hold a car and then break, I do not want a broken bridge. It took me about 2 months to complete it (December 2014 - January 2015). The original arc shape was the hardest to get right. I thought about making a huge compass, but that was impractical. I decided to bend a ruler and trace to the formed arc. This turned out to be a very elegant solution. I made toothpick squares and laid them out on the arc on graph paper. From there I built it layer by layer. It slowly formed a solid triangle. I used wood glue instead of hot glue in this project. This was a very good choice.

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
