The Stockett Continuous-Motion Breech-Loading Mechanism is an elegant example of mechanical ingenuity. With a single turn of the crank, it completes the full sequence of breech rotation, translation, and pivot.

This YouTube video shows how the breech block moves smoothly through coordinated motion.

I'm back to silicon microelectromechanical systems
(MEMS) in Neuchâtel, Switzerland.
You are interested in quantum mechanics and come across a lecture given by Richard Feynman in 1964.

Unfortunately, the audio recording is of poor quality, which is common for that period. So you decide to use artificial intelligence

🎞️ Just released a new video!

A DIY experiment using a holographic diffraction grating film to observe 𝗙𝗿𝗮𝘂𝗻𝗵𝗼𝗳𝗲𝗿 𝗹𝗶𝗻𝗲𝘀 — the dark absorption lines in the solar spectrum.

Also includes spectrometer measurements, fluorescence with olive oil + blue LED, and a teardown of the Ocean Optics USB2000.

🌞 It's the summer solstice in the Northern Hemisphere —
the perfect time to try a DIY physics experiment: Observing the Fraunhofer absorption lines of the Sun.

With the naked eye, you can clearly observe dark lines — these are the Fraunhofer absorption lines in the solar spectrum.
Mars orbits the Sun in 687 days, nearly twice Earth's 365-day orbital period. Mars' apparent retrograde motion occurs approximately every two years, when Earth catches and passes Mars.
