David Denby on grief and anger over the death of Philip Seymour Hoffman: http://nyr.kr/1exVuAF
“Most of the young men developed over the past twenty years—or, properly, created by the marketplace—have been buffoons, including Jim Carrey, Ben Stiller, Adam Sandler, Will Smith, and now Seth Rogen. And many more. When we lose a dramatic actor like Heath Ledger, he’s not likely to be replaced. And the same is true for a man in his forties like Hoffman. His death leaves an enormous hole that big-studio Hollywood has no commercial reason to fill. It will take the independent cinema years to find his equal.”

Humanity: You’re doing it right.
THIS is what Religion is supposed to be, Take your bigotry elsewhere.
I’ve said it before.
I’ll say it again.
THIS. Is what HUMANITY is supposed to be.
Hell yea people
It’s a holiday miracle!
Without further ado, Tumblr for iPad is finally here. We hope you like it as much as we do.
(And don’t forget — Tumblr is awesome on your Android tablet too!)
In fluid dynamics, we like to classify flows as laminar—smooth and orderly—or turbulent—chaotic and seemingly random—but rarely is any given flow one or the other. Many flows start out laminar and then transition to turbulence. Often this is due to the introduction of a tiny perturbation which grows due to the flow’s instability and ultimately provokes transition. An instability can typically take more than one form in a given flow, based on the characteristic lengths, velocities, etc. of the flow, and we classify these as instability modes. In the case of the vertical rotating viscous liquid jet shown above, the rotation rate separates one mode (n) from another. As the mode and rotation rate increase, the shape assumed by the rotating liquid becomes more complicated. Within each of these columns, though, we can also observe the transition process. Key features are labeled in the still photograph of the n=4 mode shown below. Initially, the column is smooth and uniform, then small vertical striations appear, developing into sheets that wrap around the jet. But this shape is also unstable and a secondary instability forms on the liquid rim, which causes the formation of droplets that stretch outward on ligaments. Ultimately, these droplets will overcome the surface tension holding them to the jet and the flow will atomize. (Video and photo credits: J. P. Kubitschek and P. D. Weidman)
Chinese Researchers Achieve Quantum Teleportation at Macro Scale
So by entangling two photons, for instance, physicists have demonstrated the ability to transmit quantum information from one place to another by encoding it in these quantum states—influence one of the pair and a change can be measured in the other without any information actually passing between the two. Researchers have done this before, between photons, between ions, and even between a macroscopic object and a microscopic object.
But now Chinese researchers have, for the first time, achieved quantum teleportation between two macroscopic objects across nearly 500 feet using entangled photons…
The two bundles of rubidium atoms that served as sender and receiver are more or less analogs for what we hope will someday be our “quantum Internet”—a system of routers like the ones we have now that, instead of beaming information around a vast network of fiber optic wires, will send and receive information through entangled photons.
So in a way, this is like a first proof of concept, evidence that the idea works at least in the lab. Now all we have to do is figure out is how to build several of these in series so they can actually pass information from one to the other. To do that, we only have to somehow force these quantum states to exist for longer than the hundred microseconds or so that they last now before degrading. Sounds easy enough.
