Skipping stones takes a little practice and finesse, so Mark Rober enlisted his extended family to help build the perfect rock-skipping robot. Their creation, named Skippa, ended up helping humans learn, too.
I built a rock skipping robot with the help of my nieces and nephews to understand the perfect way to skip a rock. In the end we learned that 4 things matter most:
1) Rock angle of 20 degrees
2) Rock PATH angle of 20 degrees
3) Spin the rock as much as possible
4) Choose a rock that is flat on the bottom and as heavy as possible for you to still get to your max arm speed.

In the early 20th century, Arthur Earland and Edward Heron-Allen volunteered at what’s now called the Natural History Museum, London (NHM). The two men spent their time researching fossils of single-celled organisms with shells, called Foraminifera, cataloging the various species, and creating microscope slides of the specimens. But each year when Christmas came around, they […]
Michael Nielsen was a Fulbright Scholar who got his Ph.D. in Physics at 24. He was already tenured when he decided just three years later to shift his attention to helping democratize Science. He’s published three books, most recently Reinventing Discovery: The New Era of Networked Science. Currently, he’s a Research Fellow at YC Research […]
In the year 2,000, Susan Potter, then 72, donated her body to medicine. After Potter died, scientists froze her corpse, sliced it into 27,000 slivers thinner than a human hair, photographed each slice, and created “the world’s most advanced virtual cadaver using the highest-quality imagery of an entire human body in existence.” Not only is […]
For the true audio enthusiast, there’s a lot of difference between putting on some songs “for background music” and a true listening experience. For the latter, there’s nothing like a pair of sturdy headphones and the powerful speakers that come with them. And the wireless variety doesn’t get much more powerful than the TREBLAB Z2 […]
Digital or analog, there’s a path of least resistance for any project. Finding that path is what the Agile methodology is all about, which is why proficiency in it is a must for any project management position – and the paycheck that comes with it. And the quickest path to learning Agile? The Agile Project […]
Everybody’s flown a paper airplane. But what if you could fly on a paper airplane? Until we invent shrink-ray technology, the PowerUp X FPV Video Paper Airplane Kit will have to do – but it’s as fun as that sounds and more. The original version of this creative toy added drone tech to the old, […]
