A Tesla Speed Record: Model S Plaid Scores Big

Add another Tesla speed record to the trophy case. This time? The speed record for unmodified consumer vehicles. New Tesla Track Record Recently, the new Tesla Model S Plaid was tested for its speed at the world-famous Nürburgring test track. The Model S turned out to be more efficient than expected. It broke the speed…

World’s First 3D-Printed Unreinforced Concrete Bridge

A freestanding, unreinforced bridge for pedestrians made from 3D-printed concrete blocks opened in Venice, Italy. They named it Striatus. Though, it doesn’t carry pedestrians over any of the city’s famed Venice canals. This first-of-its-kind structure opened at the Giardino Della Marinaressa during the run of the 2021 Venice Architecture Biennale. Who built Striatus? ETH Zürich’s…

Why Your Solid State Drive Failure Is Going to Be Horrible

Your computer’s inevitable solid state drive failure is going to give you a very bad day. Maybe. To create amazingly fast solid state drives, engineers had to exploit quantum mechanics. But, it comes with a cost. Quantum Mechanics and Hard Drives Quantum mechanics is all around us. Most of the time, we are not aware…

Why are oil prices negative?

Oil prices are negative, say headlines everywhere. How is that possible? Oil prices aren’t actually negative–but it’s a great headline. How oil is priced is very complicated. So here’s a simplified analogy that will give you the big picture. Pretend oranges are SUPER important to modern society. (An orange a day…) Every day, if you…

Considering all the nuclear waste, why is nuclear power considered clean?

Nuclear energy is a very misunderstood topic. Issues include the risk of meltdowns, radiation, and how to store nuclear waste. Why do some people think that nuclear power is clean, considering all the waste? Because the numbers are very clear. “All the waste” from nuclear is still much less wasteful than burning fossil fuels. Here’s…

The Drinking Bird Toy That Even Einstein Could Not Explain

If you have seen the classic drinking bird toy, then you have probably wondered how it works. You might not have succeeded in explaining why it works. Some say that Einstein was baffled by it. Engineer Bill Hammack disassembled the drinking bird toy to understand the principles behind it. What looks like red water inside…

Final Answer: The EmDrive Is A Fake

Science says the EmDrive is a fake. Its creator designed the EmDrive as an engine for space travel. The EmDrive uses a RF resonant cavity thruster. This should create thrust without any propellant. Traveling around and carrying all your fuel with you gets very expensive, and a propellant-less thruster would change space travel forever. Unfortunately,…

10-Cent Broken LED Renders Billion Dollar Telescope Unusable

This is such a lovely story of an engineer who knew his stuff and saved the day! The W. M. Keck Observatory is a two-telescope astronomical observatory near the summit of Mauna Kea in the U.S. state of Hawaii. The total funding to the Keck telescopes is in the billions of dollars, and it’s responsible…
