Mathematics Changes Kilogram
As you may know, for more than a century, Kilogram has been defined by a platinum-iridium cylinder kept in a high security vault outside Paris. Kilogram is the last SI unit that was still defined by a physical representation. Over the years, the units have been changed from their physical definition due to unstable nature of a physical object in the passage of time. For some years, there have been efforts to do the same for Kilogram. Finally two different teams, through different methods, have come up with a mathematical definition based on constants that is both precise and in agreement with each other for the metrologist community to be able to change the old physical definition of Kilogram. This redefinition will not give us a more precise Kilogram but will make the exact Kilogram measure more available to anyone anywhere on the planet without access to the actual cylinder.

In September, a Danish astronaut, Andrea Morgensen, used a new tactile technology to remotely control a robot on Earth to insert a pin in a hole while he was orbiting Earth onboard of ISS.
The blue and white fiberglass robot, Earthbound Interact Centaur rover, is equipped with a pair of arms designed for high-precision work and a camera on its head for the controller to see. Of course, none of these sound new but the remarkable part of this experiment is the fact that Morgensen could actually feel the pin going in the hole in real-time. So if the pin wasn't properly aligned, he would feel the sides of the hole resisting its insertion.
This new tactile technology opens the door to many exciting possibilities. To read more, please visit:
