Not quite the Deutscher Bauernkrieg. This one’s coming from 172 economists, led by Hans-Werner Sinn who published an open letter demolishing Angela Merkel’s economic policies in favour of a European banking union. The letter was published two days ago in Frankfurter Allgemeine Zeitung.

Is this an Economists’ Revolt, after the Manifesto for Economic Sense?

.

Richard Layard has become (once again) something of a household name after the publication of the Manifesto for Economic Sense, which he wrote with Paul Krugman.

Baron Layard (he is a Labour peer) rose to prominence after having lobbied the Blair government to include happiness economics in its policies. The results have been mixed. But that is to be expected. The real world has a nasty habit of derailing the best-laid plans.

On the substance though, Layard is right.

No technicolour here, but this is what it actually looks like.

‘Twisted light’ carries 2.5 terabits of data per second

Bo Thide of the Swedish Institute of Space Physics and a team of colleagues in Italy recently demonstrated the encoding of data using the orbital angular momentum of light, sending two beams made of different OAM states across a canal in Venice. Casanova would have been delighted.

Radio spectrum policy groups should be delighted too. The two beams were in fact incoherent radio waves, with the same frequency, but with different OAM states. With the airwaves getting crowded, this could be the next big thing.

I endorse this radio message
