Nikola Tesla, with over 300 patents to his name, is best known for his groundbreaking work in electricity and radio. He may have been the first to discover X-rays, but a devastating fire in 1895 destroyed much of his laboratory, setting back his research.

Shortly after, German physicist Wilhelm Röntgen published his findings on X-rays. Rather than feeling discouraged, Tesla congratulated Röntgen and even sent him some of his own X-ray images, which Röntgen praised. Undeterred, Tesla continued his experiments, developing high-energy vacuum tubes powered by his Tesla coil. These allowed him to produce highly detailed X-ray images, which he called “shadowgraphs.” He even captured images of his own body, including his hand and foot.

Despite his remarkable contributions, Tesla struggled with financial difficulties and personal setbacks later in life. He spent his final years in solitude and passed away at the age of 86.

During the 1980s, you’d notice cotton and wool dominating men’s clothing fabrics. Acrylic became a favorite for its affordability and softness, while polyester surged for casual wear, balancing durability with modern style.

Layering became essential, with vibrant sweaters over turtlenecks in the 1980s. Influences from pop culture shaped your style, mixing casual and glamorous elements for a unique fashion statement.

Harold Agnew saw the completion of the atomic bomb from start to finish. As a member of Enrico Fermi’s research team at the University of Chicago in 1942, Agnew witnessed the first sustained nuclear chain reaction, Chicago Pile-1. He worked in the Experimental Physics Division at Los Alamos from 1943 to 1945. While the Trinity test was being conducted, Agnew was already on his way to Tinian Island in the Pacific as part of Project Alberta, the group responsible for the final bomb assembly. He flew as a scientific observer on a B-29 bomber for the Hiroshima bombing mission, measuring the size of the shock wave to determine the bomb’s power. He also filmed the explosion with a movie camera.

The plutonium core (the box) in the Fat Man weighed 6.2 kg or about 14 lb, the pit is 9 cm (4 inches) across. And only about one fifth of it, a bit over 1 kg (2 pounds) undergoes a fission reaction. And only a gram (1/30th of an ounce) of that gets converted into explosive energy equal to 21,000 tons of TNT.
