Without water filtration, well, you'd probably be dead. That's it.

OK, maybe there is a little more to it. We've explored the history of water filtration, going back as far as 4,000 years, all the way up to modern methods such as activated carbon, resin filters, and reverse osmosis. YES! Even reverse osmosis, whatever that is. 

Learn how water filtration began, how the processes work and evolved, and why we still have water shortages even though most of the planet is covered in water.

When you think about famous architects, only one comes to mind. OK, maybe a bunch come to mind. When you don't know anything about architecture, and you live in Pennsylvania, only one comes to mind, and that is Frank Lloyd Wright!! 

From his most iconic home, Fallingwater, to Taliesin, Unity Temple, and more, the impact that Frank Lloyd Wright had on architecture is nearly unparalleled. Learn about his greatest successes, some failures along the way, and how he impacted architecture in this totally not a new series of Unprofessional Engineering!

Great Architects: Frank Lloyd Wright - Episode 332

Aluminum is used in countless items that you interact with each day. The combination of strength and light weight make it one of the most diverse materials used for consumer goods, construction, and more. 

Join us to learn everything that it takes to make aluminum, where we discuss the Bayer process, Hall-Heroult process, the Cheremkhovskaya-deep mine in the Urals, and anything else one might want to know about smelting aluminum.

How Is Aluminum Made? - Episode 334

If you are thinking about Civil Engineering, or are already a Civil Engineer, there is really only one thing that you need to know about. Concrete!! 

Need to build a road? Concrete. Need to build a sewer? Concrete. Need to build a canoe? Umm... yup, Civil Engineers use concrete for that as well! In fact, colleges around the world have teams that pride themselves on the building the fastest, most agile, and (most importantly) buoyant canoe possible. 

Learn how one goes about making concrete float, the steps it takes to build the canoe, the other boring parts that go into the ASCE Concrete Canoe competition, and more!

ASCE Concrete Canoe Competition - Episode 335

Are you in the market for a new car? Do we have a deal for you!! For just the small price of 3 million to over 13 million dollars, one (yes one) of these cars could be yours!!!

Learn what separates a sports car from a supercar, and then what sets the hypercar apart from the rest. From top speed and acceleration to the top end components used in the design, hypercars are worth the price! OK, maybe not that, but they are engineering marvels. We also discuss the first hypercar, the best hypercars available, and the most expensive ones possible.

What Are Hypercars? - Episode 336

With the emergence of the Soviet Flanker and Fulcrum, the United States Air Force realized there was a need for a new Advanced Tactical Fighter. That new ATF was the F-22 Raptor, a stealth tactical fighter developed by Lockheed Martin and friends. 

We look into the engineering innovation that was needed to design the F-22, from new composite materials to crazy stealth technology that makes the F-22 appear to be the size of a bumble bee on radar. How is this even possible?! You'll have to listen to find out!! Or Google it... but mostly just listen.

Lockheed Martin F-22 Raptor - Episode 337

Continuing our series on companies that built the world, we've finally landed on one whose projects have already earned their on episodes; Lockheed Martin! 

Fun fact: Lockheed Martin didn't become a thing until 1995, but Lockheed Corporation and Martin Marietta were around well before. From the F-117 Nighthawk to the SR-71 Blackbird, and a ton of things in between, we look at all of the major accomplishments of this (or these?) company and how it became one of the companies that built the world!

Companies That Built the World: Lockheed Martin - Episode 338

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!

How Does Nuclear Fusion Work? - Episode 339

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 Golf Balls Are Made - Episode 340

After seven years and 340 episodes, it is time for us to say goodbye to our amazing Unprofessional Engineering listeners. It has been a great run and we appreciate all of the emails (nice and otherwise), social posts, and care packages that were sent our way. Hosting this podcast was one of the most enjoyable things that I have been part of (and I assume Luke as well) and hope that you all enjoyed it as much as we did. Who knows? Maybe someday we will be back! No, no we won't...but, I'll still say it. 

Oh, and this episode!! It is just us hanging out talking about our experience in podcasting, our favorite and least favorite episodes, the ones that were most successful, our favorite moments over the years, and more!!!

Thank you again for the millions of listens, hours of your lives spent listening to us get information wrong, and kindly not pointing out all of our mistakes. If you want to let us know how mad you are that we're out, go ahead and email unprofessionalengineering@gmail.com and I will for sure get back to you. Also, I will not get back to you, but you can send 'em anyway! See ya!

All Good Things Must Come to an End - Episode 341
