As We Enter a New Quantum Era: Michele Mosca Public Lecture
Published on Oct 6, 2016In his public lecture at Perimeter Institute on Oct. 5, 2015, Michele Mosca (Institute for Quantum Computing, Perimeter Institute) explored quantum technologies – those that already exist, and those yet to come – and how they will affect our lives.

Launched in November 2013, Swarm is providing unprecedented insights into the complex workings of Earth’s magnetic field, which safeguards us from the bombarding cosmic radiation and charged particles.
Measurements made over the past six months confirm the general trend of the field’s weakening, with the most dramatic declines over the Western Hemisphere. SEE: Swarm reveals Earth's changing Magnetism

|Mean Gravity Field|
On planet Earth, we tend to think of the gravitational effect as being the same no matter where we are on the planet. We certainly don't see variations anywhere near as dramatic as those between the Earth and the Moon. But the truth is, the Earth's topography is highly variable with mountains, valleys, plains, and deep ocean trenches. As a consequence of this variable topography, the density of Earth's surface varies. These fluctuations in density cause slight variations in the gravity field, which, remarkably, GRACE can detect from space.
