Do you ever wonder how airships worked or why they stopped being used? In this episode we go into the history of the airship, why they were more efficient than modern airplanes, and why they were suddenly out of commission. These giant monsters functioned more like objects floating on water than true airplanes, which is what made them so fuel-efficient. Tune in to learn even more about these magnificent machines!

The engineering world revolves around math, with every important part in a design involving complicated arithmetic. For the longest time, the time before a product could be released depended heavily on how fast the math team could get their work done, which often took ages to finish due to human processes and checking for mistakes. However, the arrival of the mechanical calculator completely changed that, reducing time drastically while improving efficiency at the same time. This invention was almost like the discovery of fire in how important it was to the math and engineering world. Tune in to see how these old calculators operated with their rotating dials and cylinders!

When most people think communication, they often think about the phone that they have in their pocket. However, communication didn't start off like that, and was actually just based on a language of dots and dashes, and by a bunch of wires and a device that looked like a complex hammer. Telegraphs are the basis of all communication today, showing that instant, long communication is possible no matter how hard to understand it may be at first. Tune in to learn about how a simple system grew to connect countries around the world!
