In 1995, physicists at CERN announced that they had successfully created the first atoms of antihydrogen at the Low Energy Antiproton Ring (LEAR). The researchers allowed antiprotons circulating ...

These combine to form positrons, antiprotons, and antineutrons, which is mostly what we are concerned with when we commonly talk about antimatter. There are also more elementary antiparticles like ...

However, CERN is capable of making just ten nanograms of antiprotons per year. Generating a single gram of antimatter — the amount needed to test a propulsion system — would require $4 million ...

Clustering algorithms are at the basis of several technological applications, and are fueling the development of rapidly evolving fields such as machine learning. In the recent past, however, it has ...
