Witness: Kay Kay: The Girl from Guangzhou

Kay Kay is the face of modern-day China - a bright, educated and ambitious 20-year-old living in the booming southern city of Guangzhou.

She represents a new generation of middle class Chinese 'only' children, benefiting from China's economic growth as well as the single-minded dedication of her factory-worker parents.

This unique film has followed her for her whole life, filming her and her family every year since her birth in 1992.

It gives a rare, personal narrative to the decades of transformation that China has undergone. From her childhood and school days through to her university life where she struggles to get to grips with China's economic imperatives in the face of environmental issues.

Kay Kay is a charming, engaging guide to modern China, its people and the country's recent economic boom.

Simulation of a binary boson star merger

Author: Frans Pretorius, Department of Physics, Princeton University, specialist in numerical solution of the field equations of Einstein for gravity. The non-linearity and complexity of Einstein's equations make it challenging to solve even numerically, and some portion of his time is spent designing algorithms to efficiently solve the equations in parallel on large computer clusters, and software to manipulate and visualize the simulation results.

The video shows a binary boson star merger. Technically a boson star is a spherically symmetric static solutions of Einsteins field equation coupled to a scalar field (when they are free of singularities, otherwise they are black holes). Until today there is no observational evidence for the existence of a boson star. In fact, they are made of scalar elementary particles, and none has been discovered yet. Boson stars are hypothetical candidates for supermassive objects at the center of galaxies. In fact, for the supermassive object at the center of our own galaxy, evidence points towards a black hole, but the possibility that it is a boson or fermion star cannot be completely excluded so far.

Quantum Mechanics (Chapter 5 of 6)

Once you get past existence coming and going... and virtual particles... and uncertainty... and exclusion, then you are ready to enjoy the REALLY weird stuff in the quantum world.
