Friends, don’t let friends play Pokémon go alone unless they are known to be very situationally aware.  One or two images will show the problems that arise from not watching what you are doing while playing this game.  Consider where the “Pokéstops” are located.   By the by that is a name which is just begging for a double entendre meaning.    Much of the danger stems from the very thing that makes this game almost unique, it is based on augmented reality.  The space you play in is comprised of the very streets, buildings, and hazards of the real world.   Hence you need to be as warry as you would in the real world.

It did promote physical activity.

The concept origin of space-time itself as a emergent property of a collection of fundamentally quantum systems without a notion of space-time is not new. When this is done usually certain presuppositions are made about the nature of the underlying quantum system. In a recent paper posted to the arXiv by scientist out of Cal Tech develop aversion of this approach in which noting is assumed about the quantum system at the smallest scale. (Chun Jun Cao, 2016)

Systematic structural racism is not just a White-Black thing.  A Black man is less likely to be hired for a job with a community college degree than a white man who has just gotten out of prison.

Brexit, if it happens as we all fear will make the UK the Puerto Rico of Europe. No, not really... Puerto Rico has more rights as a commonwealth of the US than Britain will have in association with the EU. Puerto Rico can stay outside the union while people of that semi independent nation are full citizens of the union with free trade, free movement, and even serve on our supreme court.  All they need to do to join is hold a binding referendum and have statehood win with a 2/3 vote on a high voter turnout.

Sexual Harassment in academic scientific context, why did it shock us?    What we learned over the last six months is that scientist male and female are still human.   Humans when placed in social context will behave like social and sexual animals that we all are.  Schools are not a safe space from this due to simple human nature.   That said, being the thinking animals that we are we need to know how to control and at least manage those impulses.  Now that the shock has worn off, the veil has come off, and we know scientist are just human.  Some common sense would’ve avoided all of this.

Information is not destroyed but it is even more scrambled up than anyone thought by black holes. I have used the framework of relativization, to compute the temperature of the proposed firewalls.  It would be about 1.410 septillion Kelvin.   Relativization which has been developed in open peer reviewed literature and conference presentation in to a comprehensive theory combining General Relativity with Quantum Field Theory.  Black holes shred information, then burn it in a furnace hotter than millions of Suns.
