When it comes to telling time with an analog clock, the idea of gear reduction is a very critical piece of the puzzle. Basically, a set of multiple gears work in concert to gradually rotate at slower speeds.
If you live in a house constructed with a wood frame or wooden siding, this is the last thing you ever want to buy. But if your dwelling is made from brick, concrete, stone, metal, or glass, read on…
Do you want to see what termites can do to a piece of wood?
Computer graphics have come a very long way in the past couple of decades, offering up images which are becoming more and more difficult to distinguish from reality. Especially notable are the improvements in physics engines, which allow objects to move and behave more like they do in real life.
When it comes to wall-climbing robots, most of them rely on vacuum suction to make their way up the side of a building. The trick there is that you need a very smooth surface, like glass or marble in order to get a good grip.
Did you ever see the Black Mirror episode called “Arkangel?” Basically, it tells the story of an overly-cautious mother who has a chip implanted in her daughter’s brain so she can track her every movement. But she also upgrades it with a couple of features, like the ability to see everything she sees, and to block out images of anything that might be deemed “shocking.”
Scientists will tell you that no human or animal can accurately predict an impending earthquake before it starts. However, certain animals are far more sensitive to seismic activities than humans. With that in mind, one seismologist has tossed out a wildly impractical but amusing idea for an early earthquake alert system – using cats.
PhD geophysics student Celeste Labedz posted her idea in a multi-part Twitter thread last week, and it’s well worth a read.
Growing up, I always thought taking a chemistry class would be awesome. I figured that it would be all fun and games making stuff that oozed and blew up. Once I grew up and went to college, I finally took a chemistry class.
When it comes to augmenting the human body with technology, video games and science fiction movies have us dreaming of giant mech-like exosuits, arm-mounted missile launchers and flamethrowers, and superhuman vision and hearing. What we’ve got for now is a robotic tail.
Developed by researchers at Japan’s Keio University, the Arque is a robotic appendage that gives its wearer a mechanical tail.
In a quest to make virtual characters more realistic, engineers have been working on ways to make their skeletal structures and muscles more like those found in living beings. Recently, a technology was shown off which takes those simulated biological components to the next level.
Engineers Seunghwan Lee, Kyoungmin Lee, Moonseok Park, and Jehee Lee published the paper Scalable Muscle-actuated Human Simulation and Control, which includes a humanoid digital model with a full skeleton and 346 muscles The digital characters can even learn to kick, jump, run, and even lift weights.
Tardigrades are one of the strangest creatures known to exist. These microscopic organisms – also known lovingly as “water bears” are best known for their incredible ability to survive just about anything. Apparently, they can survive extreme temperatures, complete dehydration, and even the vacuum of space.
Crayon labels are kept pretty basic for a good reason. The colors really don’t need much of a description. Besides, kids don’t know what Periwinkle, Scarlet, or Aquamarine are. They just want to color between the lines in their book.
If you’ve ever wondered why it’s so important to properly pressurize and depressurize a submarine, this image should explain it for you. What you’re looking at is three identical styrofoam heads, each of which has been exposed to a different depth pressure.
Posted up on Reddit by contributor SpyTrain_from_Canada, the picture shows just how nasty the pressure can get as you descend into the ocean.
Any thoughts that you had about running through a door to find safety from killer robots is now useless. These drones are no bigger than the palm of your hand, but they can work together to open a door.
Scientists often use nature as a guide when creating new robots, making machines that mimic the behavior and movements of animals. But if you are copying a fish, that won’t do any good on land. Just like a robot based on a lizard won’t do you any good in the water.
I’ve never really trusted those fitness trackers. There’s just no way they can get accurate results. Actually, that’s just something I say to justify those extra doughnuts this morning. But that doesn’t mean there isn’t some validity to my concerns.
