Early astronomers used observations on the moon’s phases to deduce the spherical nature of celestial objects and eventually to develop the heliocentric model that we all know and love today. Astrologers saw deep meaning in the phases of the moon and used that to create an entire mythos. The moon and its phases are important […]
The recorder is a type of flute that is very popular in elementary schools because the instrument is so simple and inexpensive. If you were born in the last four decades and grew up in a western country, then there is a very good chance that you were required to learn how to play some […]

The childhood classic tabletop game of Connect Four entails dropping either a red or yellow disc into one of several columns in a grid with the hope of lining up four in a row. And even though the game has existed digitally for a while now, it is mostly played on LCD screens with fancier […]
Health tracking is a vital component to recovering after an injury or simply trying to improve one’s own fitness, and although accelerometer-based devices are decent at tracking general activity, they fail to accurately monitor specific areas of the body such as joint movement. This is why a team of researchers from the Singapore University of […]
If you’re anything like every other human being on the planet, you have several cordless power tools and their batteries are all dead. You never remember to put the batteries on their chargers until you need the tool for a job only to realize that it won’t turn on. Discipline is difficult, so Lance of […]
You’ve probably heard that there isn’t any sound in space. That’s because sound is vibration traveling through a medium, like air or wood, and space is a mostly empty vacuum. The frequency of the vibration in a medium is the pitch of the sound and the amplitude is the volume. If you want a way […]
Counting one’s coins by hand can take a very long time, and for those wanting to avoid physically going to the bank or paying a fee at a commercial machine, what options remain? Fraens has created a full 3D-printed coin sorter and counter that combines technology with a clever design to accomplish this task automatically. The bulk of […]
