The inverse-square law describes how physical phenomena like light intensity decrease with the square of distance from a source. The article explains the mathematical foundation of this law by deriving the surface area formula of a sphere through a geometric projection from a cylinder, demonstrating why intensity follows an inverse-square relationship in three-dimensional space.
An article exploring the author's reconsideration of Russian camera lenses and optics after initially dismissing them based on limited experience. The author acknowledges their tendency to make quick judgments (thin-slicing) and decides to reassess Russian lenses by obtaining a high-quality example to fairly compare against the opinions of Russian lens enthusiasts.
NASA's Nancy Grace Roman Space Telescope, launching in 2026 to orbit at the Sun-Earth Lagrange Point 2, will use advanced optics and direct imaging to discover hidden exoplanets and study dark energy and dark matter. The mission employs Wind River technologies and collaborates with ESA and other partners to operate autonomous, precision-controlled systems in the harsh deep space environment.
