The final years of the 19th century were a hotbed of scientific innovation. In 1895, German physicist Wilhelm Roentgen was experimenting with cathode-ray tubes in his lab when he noticed a nearby fluorescent screen began to glow. He had accidentally discovered a new, unknown type of radiation which he called "X-rays," with the "X" signifying their mysterious nature. This discovery would fundamentally change the world of medicine, allowing for the first time a non-invasive look inside the human body.

Twenty years later, in 1915, the world of entertainment saw its own revolution with the release of D.W. Griffith's film, *The Birth of a Nation*. The movie was a technical marvel, introducing groundbreaking cinematic techniques that would influence filmmakers for generations. However, it is also one of the most controversial films ever made due to its racist glorification of the Ku Klux Klan and its distorted portrayal of the Reconstruction era, sparking nationwide protests upon its release.

Jumping forward another sixty years, 1975 marked the beginning of a long and tragic conflict in the Middle East. Tensions that had been building for decades between Lebanon's Christian and Muslim populations, exacerbated by various political and paramilitary factions, finally erupted into a full-scale civil war. The brutal conflict would last for 15 years, causing immense destruction and fundamentally reshaping the country's political landscape.
