Ovid among the Scythians Eugène Delacroix 1862 MMA "The mind sinks into it with a slow and appreciative rapture, as it would sink into the heavens, or into the sea’s horizon—into eyes brimming with thought, or a rich and fertile drift of reverie" Baudelaire

Leonard Susskind

Lost in the landscape – CERN Courier

20 years since coining the string-theory "landscape", Leonard Susskind describes the emerging connections between quantum mechanics and gravity.

What have been the most important and/or surprising physics results in your career? I had one big negative surprise, as did much of the community. This was a while ago when the idea of “technicolour” – a dynamical way to break electroweak symmetry via new gauge interactions – turned out to be wrong. Everybody I knew was absolutely convinced that technicolour was right, and it wasn’t. I was surprised and shocked. As for positive surprises, I think it’s the whole collection of ideas called “it from qubit”. This has shown us that quantum mechanics and gravity are much more closely entangled with each other than we ever thought, and that the apparent difficulty in unifying them was because they were already unified; so to separate and then try to put them back together using the quantisation technique was wrong. Quantum mechanics and gravity are so closely related that in some sense they’re almost the same thing. I think that’s the message from the past 20 – and in particular the past 10 – years of it–from-qubit physics, which has largely been dominated by people like Maldacena and a whole group of younger physicists. This intimate connection between entanglement and spatial structure – the whole holographic and “ER equals EPR” ideas – is very bold. It has given people the ability to understand Hawking radiation, among other things, which I find extremely exciting. But as I said, and this is not always stated, in order to have real confidence in the results, it all ultimately rests on the assumption of theories that have exact supersymmetry.

Pyotr Alexeyevich Kropotkin

On a windy, rainy, spring day, I am happy I have no visitors; my hand is free, my mind relaxed and cleansed. The ancients called it yihua, the "single stroke": a thousand hills, ten thousand valleys, people, bamboo, trees,a single brushstroke and all is completed. Shi Tao 1699
