How Golf Balls Are Made - Episode 340

If you're a golfer, one thing that you know for sure is that bad shots are never your fault! Your grip might be worn down, your clubs are old, someone talked in your backswing, or you're playing with bad golf balls. Speaking of golf balls, perhaps they are bad due to their manufacturing process. We looked back to understand the history of the golf ball, from Rome to Scotland, from wooden balls to the feathery, it has been a long journey to get where we are today. We also did a deep dive on the actual manufacturing process that we use today for making golf balls. from creating the core, to defining the modulus of elasticity and compression of the golf ball, all the way up to painting your favorite brand on the front of the ball, we have it all!

How Does Nuclear Fusion Work? - Episode 339

Scientists around the world are making giant leaps in the field of nuclear fusion. OK, maybe not giant leaps, but, you know, very small steps that are still very significant for helping the world become free of their dependency on fossil fuels. Although scientists theorized how nuclear fusion worked back in the 1800s, we still haven’t been able to make a form of energy that we can rely on today. But we’re getting there! In just a few short decades, the science community is confident that we will be able to depend on nuclear fusion at a large scale. How far do we have to go? Well, just recently we were able to briefly produce more energy from a fusion reaction than it took to make happen. Sort of. Intriguing, right? That is why you’re going to have to listen to learn more!

Did your parents ever yell at you for playing to many video games? Did they tell you that video games will never help you in the future? Well, maybe they were wrong! Just don't tell them we said so... Some studies have shown that kids that play video games have better hand eye coordination and therefore make better surgeons. What about engineers? We looked through some of our favorite video games that are great training for engineers, both young and old. From old school games like Tetris and Pong, to more modern games like Sim City, Kerbal Space Program, and Minecraft, there are so many games that instill engineering principles in the players. Did your favorite make the list?

Predicting the Weather - Episode 128

Do you ever wonder how the weather person can get their predictions wrong half the time and still keep a job? Well, when you actually take a at all of the different science and technology that goes into those predictions, you might be a little more forgiving. Just a little. Meteorology is actually a complex field of study that requires more than just standing in front of a green screen and guessing if it will rain. I mean, some people just do that, but actual meteorologists are hardcore scientists. Satellites, radar, barometers, and even chaos theory come into play in their field of work. We take a look at everything that goes into predicting the weather, the way it was done in the past, and if we will ever get past the accuracy of Groundhog Phil.

One example would be the written language of the Mayans. Unlike English, it is created from 800 or so glyphs representing a syllable or word. Sure, this means most words could be spelled a few different ways, but how many languages have you created? They also nailed the 365 day calendar and created tens of thousands of paper books. Masters of hydrology and the blast furnace, in many ways the Maya were ahead of their time, even if they decided that the wheel was of no real value. Interested in learning more about their history?

Neil deGrasse Tyson - What did that guy ever do? - Episode 104

If you haven't been living in a cave for the past decade, you know who Neil deGrasse Tyson is. What you might not know is what that guy ever did to become such a well-known personality in the science community. Other than some obnoxious tweeting and always having something to say about how inaccurate your most beloved space movies are, he must have done something, right? Well, maybe not all that much. This isn't to say NDT isn't way smarter than us; it is just that he has had a different focus in life. Instead of using that massive brain of his to explore the mysteries of the universe, he has been using it, and a dash of personality, to bring awareness to science topics that would otherwise go unnoticed. Sounds kinda like what we do here at Unprofessional Engineering. Maybe he isn't the worst after all...

Bill Nye is extremely funny, just like me. We're practically the same person, so does that make me a "science guy" as well?! I think not!! But if you dig a little bit deeper, there is a lot more to Mr. William Sanford Nye. He has a couple patents, has written a couple books, helped NASA with a sundial going to Mars, designed parts for the Boeing 747 and hurt himself on Dancing with the Stars. All of these really do point to the fact that he is a science guy! It isn't his fault that he was smart enough to get out of engineering and do something he loves.
