For the first time, physicists have watched a single proton flip over on its axis. Aside from being a technical triumph, the measurement may eventually help determine why the universe contains more matter than antimatter.

Cosmologists think the Big Bang should have produced the same amount of ordinary matter — the particles that make up stars, planets and people — and antimatter, which is just like matter, only with an opposite charge. But when matter and antimatter meet, they annihilate each other. That there’s enough matter left for us to exist is one of modern physics’ biggest puzzles.

Tech Gadgets Mysteries, What Is A Digital Compass?

For your compassing solutions, the digital compass is a must have gadget. It’s a perfect gadget for compassing that is accurate and easy to use. From vehicle, aircraft, marine or personal navigation, it helps a lot. Whatever your need is, trust this gadget to get you there.

A digital compass is a compass that offers high accuracy compassing through a digital means. It is designed to use digital technology to give accurate navigations. It can give you quality ground, air and water mapping.

A digital compass is used for navigation to show directions. It is used by the military, aircrafts, vehicles etc. Personally, you can also use it for directions when navigating. Navigational needs such as airplanes, ships in the sea and cars in the streets use them.

Digital compass interests people with its accuracy and ease of usage. With an advanced digital technology that is made for utmost accuracy and superb functioning, the digital compass uses the North Pole to tell other directions efficiently.

PnP is a very simple (but flexible) LEGO robot that mimics some of the things an industrial robot can do. The arm is very basic, but can address a large workspace using two-axis spherical motion and a parallelogram mechanism to keep the “finger” level at the end. Using NXT-G and the LEGO NXT motors gives it a high accuracy, enough to place 2×4 bricks within a few millimeters of the desired position. The result is that PnP can move simple objects, and a wide variety of “work stations” can be fitted around it. It can also firmly push on things, activating levers or sliding mechanisms. Since the NXT can easily drive at least one more motor, this minimalist mechanism can easily be expanded. This was inspired by Ian Hendry’s amazing LEGO creations, and another project that seemed to require linear motion… but I wasn’t sure it did.
