Generative design/topology optimization on quantum.

Here it is with the armor on and teeth in

This guy is absolutely incredible. He does a great job at breaking down advanced concepts into understandable and even entertaining content; an absolutely brilliant engineer undoubtedly but also great at making videos.

Pink Floyd pioneered live surround sound as long ago as the early ’70s. Chris Hewitt has tracked down the groundbreaking PA systems they used at Pompeii and on the Dark Side Of The Moon tour, and rebuilt the custom quad console operated by Alan Parsons. In our exclusive video feature, Chris explains how the Floyd created a fully immersive concert experience more than 50 years ago.

A very quick overview of nearly every machine you'll see on a construction site.

It takes a lot of big tools to build the roads, dams, sewage lift stations, and every other part of the constructed environment. To me, there’s almost nothing more fun than watching something get built, and that’s made all the better when you know what all those machines do.

The video admits in the end that the title is clickbait ("Every"). There are too many to be exhaustive.

In this episode Shahriar takes a look at one of the most advanced electrical test and measurement instruments ever created. The Keysight UXR-Series Real-Time Oscilloscope brings 110GHz of analog bandwidth and 256GS/s real-time sampling at 4-channels simultaneously. To make it even more impressive, the entire data-conversion architecture is in 10-bits. This implies that the instruments captures, processes, stores and displays over 10Tb/s of information.

Various architectures of state-of-the art oscilloscopes from Keysight, LeCroy and Tektronix are examined and compared against the new real-time architecture of the UXR-Series oscilloscope. The teardown of the front-end 110GHz module along with the data acquisition board is presented and analyzed in detail. The instrument showcases a wide range of Keysight technologies implemented in various technologies such as InP, SiGe BiCMOS, 65nm CMOS and 28nm CMOS nodes. In combination with Hyper-Cube memory module, data can be captured at 25

This is one of the more mind-blowing DIY projects I have seen. The quality of workmanship is absolutely next-level. Even though everything is in German, the video is pretty clear.

Love its very distinctive sound. It features two turboprop engines mounted in pusher configuration. It is the fastest civil turboprop.
