A 10-minute clip from a Jonathan Blow Twitch stream in which he argues that game engines do not really need separate scripting languages. He questions the value of embedded interpreters when the main language can do the job.

Physics Girl creator Dianna Cowern shares an update on her health, struggling with long COVID and ME/CFS. It includes documentary footage and links for supporting her recovery.

A short, humorous critique of Helion Energy's fusion approach, framed as a response to a Real Engineering video. It covers low reactivity, neutron production, bremsstrahlung losses and diagnostics.

Dave Plummer, a retired Microsoft engineer who wrote Task Manager, responds to the claim that Windows sucks. He describes how he would fix common annoyances, in what he calls a love letter to Windows wrapped in a rant.

Thunderf00t critiques SpinLaunch, the startup that proposes flinging payloads to space with a giant centrifuge. He argues the physics and engineering do not hold up.

Sabine Hossenfelder reads a confidential email and uses it to explain her worries about academia and incentives in theoretical physics research. She ties it to her earlier Nature Physics comment on research quality.

h3h3Productions describes how a hacker took over their phone number by getting a SIM card from T-Mobile, and gives security advice such as using a hardware key and an authenticator app.

Thunderf00t argues that Zero Mass Water's solar-powered atmospheric water generator is essentially a dehumidifier with solar panels. He critiques its economics and physics, especially in arid places.

Sabine Hossenfelder explains why she left academia, criticizing its incentives, funding and career structure. She gives a personal account of the social problems in science.

Dave Jones of EEVblog debunks the uBeam ultrasonic wireless phone charging technology and explains why it is not practical. He covers efficiency, coupling loss and safety, and responds to the founder's remarks about engineers.

Thunderf00t's second video critiquing SpinLaunch, the company that proposes flinging rockets and payloads into space with a giant centrifuge. He argues the idea is physically unworkable.

A former fusion scientist argues why fusion power by 2040 is unrealistic, covering the physics challenges, neutron issues and optimistic company claims, with a brief note of good news.

Adam Something argues that the Hyperloop is impractical, covering the costs and engineering problems of running trains in a near vacuum compared with conventional rail and metros. The description admits some wrong numbers in the original cut.

Veritasium argues that every new technology, from motion pictures to TV, was predicted to revolutionize education and none did. It asks what actually could, drawing on the host's physics education research.
