Here at PopSci, there's nothing we love more than figuring out how something works, be it the latest technology, or a scientific breakthrough. That moment of discovery - let's call it a "how it works moment" - is almost as exciting for us buffs as it is for the researchers.
Here, we take a look back at some of history's most fascinating "how it works moments" and the images that define them. It's not always a cutaway or a teardown, but our desire to see how things work with our own eyes hasn't changed over the years.
The incredible innovations, like drone swarms and perpetual flight, bringing aviation into the world of tomorrow. Plus: today's greatest sci-fi writers predict the future, the science behind the summer's biggest blockbusters, a Doctor Who-themed DIY 'bot, the organs you can do without, and much more.
