"fiercer form than thirsty stallions amorous"
some phrases can not be unread.
Physicists have devised a way to take pictures using light that has not interacted with the object being photographed. This form of imaging uses pairs of photons, twins that are ‘entangled’ in such a way that the quantum state of one is inextricably linked to the other. While one photon has the potential to travel through the subject of a photo and then be lost, the other goes to a detector but nonetheless ‘knows’ about its twin’s life and can be used to build up an image. Normally, you have to collect particles that come from the object to image it, says Anton Zeilinger, a physicist at the Austrian Academy of Sciences in Vienna who led the work. “Now, for the first time, you don’t have to do that.” One advantage of the technique is that the two photons need not be of the same energy, Zeilinger says, meaning that the light that touches the object can be of a different colour than the light that is detected. For example, a quantum imager could probe delicate biological samples by sending low-energy photons through them while building up the image using visible-range photons and a conventional camera. The work is published in the August 28 issue of Nature. Zeilinger and his colleagues based the technique on an idea first outlined in 1991, in which there are two paths down which a photon can travel. Each contains a crystal that turns the particle into a pair of entangled photons. But only one path contains the object to be imaged.
According to the laws of quantum physics, if no one detects which path a photon took, the particle effectively has taken both routes, and a photon pair is created in each path at once, says Gabriela Barreto Lemos, a physicist at Austrian Academy of Sciences and a co-author on the latest paper.

Step one. Suppose you clear away all the happinesses that you distrust? Step two. Clear away all the unhappinesses that you have come to trust. Get rid of them too, don’t count on your miseries or your titillations. What will be left behind? Perhaps, after you’ve cleaned all that out, you might find in the back of your cupboard something like the theme of the Goldberg Variations. A deeply trustable happiness. A tender, discombobulating — but not discombobulated! — smile with just enough sadness and loss in it to be believable, to be endurable.

a magician asks you to pick a card - any card, in fact. you do. they ask you to put the card back in the pack - anywhere in the pack, in fact. you do. they walk away. ten years later, your wife gives birth to the six of clubs. “is this your card?” the midwife asks, in a familiar voice.

the assumption that my presence makes everyone else as uncomfortable as it makes me
There’s something in the human personality which resents
things that are clear, and conversely, something which is attracted to puzzles, enigmas, and allegories.

What I, in common with his other enthusiastic readers, took from his work was a conviction and a technique. The conviction was that the everyday world might be — as to adolescents it certainly is — full of boredom and triviality, but the wider world of nature, art, and learning is full of inexhaustible interest. But it’s easy to lose sight of the latter, and let ourselves be trapped in the former. The technique, the trick for lifting oneself from the one world to the other, was simple enough: intense concentration followed by relaxation will lead to elation.
The thing is, it does work.
