T4D's Science Talks

Step back to 1962 with us for a deep dive into Frank Rosenblatt's "Principles of Neurodynamics". This foundational work introduced the perceptron, a pioneering "brain model" and theoretical nerve network that simulates how organisms learn and "perceive" the physical world. Discover how Rosenblatt's insights into these early learning machines laid critical grou...

A deep dive into a study on wild house mice in a Swiss barn, revealing a surprisingly stable social structure. Researchers used RFID tracking to observe dynamic communities that persist over seasons, even outliving individual mice. These communities exhibit fission-fusion dynamics , splitting in summer and re-merging in winter. Crucially, the study highlights that female-female interactions are th...

Join us for a deep dive into one of physics' most pivotal experiments: The Michelson-Morley experiment. In the late 19th century, scientists sought to detect Earth's motion through an invisible "luminiferous ether" using the Michelson-Morley interferometer. Their meticulous experiment yielded a null result. They found no significant displacement of light, profoundly demonstrating...

Step into a chilling scientific saga with us as we explore the infamous "Death squared" experiment, famously known as Universe 25. In this deep dive, we revisit John B. Calhoun's groundbreaking (and disturbing) research on mouse populations, revealing what happens when a community faces limitless resources but finite space. Discover the surprising social and behavioral collapse that...
