If you opt for the convenience of disposable diapers over their more environmentally-friendly cloth alternatives, you probably don’t stop to think about the science that allows them to keep your baby dry at night. But engineerguy Bill Hammack has, and in a new video, he explains why you’re actually wrapping your…
One of the most impressive aspects of the Apollo space program was how NASA worked around the limitations in computer power. The smartwatch on your wrist eclipses what the Apollo space craft’s computers were capable of, so NASA’s engineers often had to rely on clever ingenuity to solve difficult problems.
You give the handle a few cranks and listen to it plink out a few seconds of Twinkle, Twinkle, Little Star, but if you were to crack open a music box and dig deep into the mechanics of how it works, you’d find some deceptively simple but brilliant engineering that’s been refined over the centuries.
There’s a good chance your brain’s already checked out on this shortened work week. But if you can still muster a thought process or two, you won’t be disappointed by Bill Hammack’s—aka engineerguy’s—latest video which explains the brilliant engineering behind the process of plastic injection molding.
Watching YouTube celebrity ‘engineerguy’—aka Bill Hammack—explain the engineering behind a gadget is far more entertaining than college ever was. And this time even moreso because he breaks down the simple but clever design that allows a Nerf blaster to fire one dart at a time.
When going to see a movie, many of us probably go out of our way to make sure the theater has been upgraded with high-res digital projectors. The golden age of film might be behind us, but as engineer guy Bill Hammack explains, the projector is still an impressive feat of mechanical design, capable of creating one of…
You probably don’t give much thought to the aluminum can holding your sweet, sweet caffeine hit at lunch. But engineerguy Bill Hammack explains why the simple cylindrical can holding your Diet Coke is actually brilliantly designed and engineered for being both easy and cheap to produce, but also strong and durable for…
Nuclear bombs are easy to make, right? Find some uranium, shove in some explosives and—BOOM!—you're quite literally done. Umm, sorry, nope. The big problem in making a nuclear bomb is that you need enriched uranium, and that's actually a real pain in the ass to make. In this video the engineering guy Bill Hammack…
Atomic clocks are super accurate, but do you know how they work? Probably not! Well, unless you know about quartz vibrations regulated by Cesium energy states at the atomic level, which are separated by magnets and ovens. But assuming you don't know that stuff, here's the engineerguy Bill Hammack explaining how…
They're the bane of pilots and moviegoers, but lasers have become an essential part of everyday life. They facilitate everything from high-speed communications, to vision-saving surgeries, to super-villain plots for world domination. But how in the hell do they get that beam of light so intense and so focused?
You probably own a ton of gadgets made from aluminum and titanium. Lot of 'em by Apple. But did you know that the smooth, brushed finish on the surface of your MacBook or iPod is actually made with a thin level of rust?
You probably take for granted the fact that turning your phone on its side automatically puts the display into landscape mode. But do you really know how the tiny accelerometer inside your device can detect those changes in orientation? After watching this video you will.
Chances are you've got a digital camera of some sort in your pocket or bag, but you've never given too much thought how it really works. Pictures go on computer, not film. Right, well, here's a simple and straightforward explanation of how that happens, exactly.
Technology has blessed us with landline phones that look like footballs and Mickey Mouse ears for decades. So why do all of our mobile phones look basically, in the grand scheme of things, the same? Here are seven good reasons.
I'm going to go ahead and guess that the computer component you take most for granted is your HDD. No longer! Bill the Engineer Guy—our favorite uncreepy uncle geek since Bill Nye—unfolds its many mysteries. [TDW Geek]
Relax! Turns out the LCD screen that makes your monitors, phones, and televisions worth watching isn't powered by wee goblins after all. Here's the most straightforward explanation to the goings-on underneath the glass that you'll find, compliments of Bill the Engineer Guy. [YouTube]
As your frustrations with waiting in line mount this holiday season, it may be some comfort to know the scientific trappings of why, exactly, you're stuck for 20 minutes behind the lady who insists on a dozen price checks.
