How to make a Fresnel lens in 3 steps. A Fresnel lens is a lightweight, compact lens made of concentric rings, designed to focus light similarly to a traditional lens but with much less thickness. Commonly used in lighthouses and optical devices, this type of lens offers an…
2021, China conducted a rare bullet train crash test, colliding two 462-ton trains at 36 km/h to study energy absorption and passenger safety. Such large-scale experiments are uncommon globally.
Nature's perfect bio-hack. 🐬 Dolphins use pufferfish as a chew toy. The lethal toxin doesn't kill them—it gets them high. They even pass it around like a joint.
A beautiful problem. The "horrible" radicals are a clever disguise for the arcsinh(x) function. The substitution x = sinh(u) makes the entire integrand collapse into a simple exponential form. #math
Drawing a nearly square shape with epicycles. Epicycles are small circles whose centers move along larger ones, used to create complex curves through simple rotations.
This is how they convert rotary motion into oscillating motion in Drill hammer

The secret behind the bulbs puzzle: only perfect squares stay ON! Each bulb is toggled once for every factor it has. Perfect squares have an odd number of factors, so they end up ON. Non-square numbers have an even number of factors, ending OFF. For example, bulb 24 has 8 factors…
In the 1930s, residents of Malmö, Sweden, woke up to an unforgettable sight when thousands of eels wriggled through the city’s flooded streets. A storm had caused the canals to overflow, and the eels, following their natural migration route toward the sea, ended up spilling…
