Thomas Jefferson is one of the most iconic figures in American history. His accomplishments include drafting the Declaration of Independence, becoming the second vice president of the United States, serving as the 3rd president of the United States, creating the University of Virginia, and the list goes on and on. There is no doubt that he had tremendous influence on his colleagues and the whole of America throughout his life, but instead of just glossing over his many achievements, let's take a deeper look into the life and legacy of Thomas Jefferson: The Architect of Independence.

World War II was without a doubt the most deadly war in history. One of the war’s most pivotal moments, D-Day, was especially brutal racking up somewhere around 15,000 deaths on both sides of the battle. However, the casualties attributed to D-Day, at least on the american side, started long before Allied forces got the opportunity to storm the beaches of Normandy. When a failed military rehearsal claimed the lives of over 1000 American soldiers. The disaster is known as Exercise Tiger, and this is the story.

The Black death, an event that decimated the population of the world. Before the Pandemic the population of the world was an estimated 450 million, after, more like 375 million. And it would take almost 300 years before the world would recover from the outbreak. But how and why did this disease cause so much destruction? Well that question can be answered through history and a little bit of science.

I am here today to tell you that all of this is false, but the truth behind X points may be cooler than the embellished stories.
