Outsourcing our thinking, since 1867 (circa)

Screenshot of a paragraph from the book "Passages from the Life of a Philosopher" by Charles Babbage. The text says:
'On two occasions I have been asked,—"Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" In one case a member of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.'

Albert Park #Melbourne #Australia #SilentSunday

A view of the city of Melbourne across a body of water. The water in the foreground is the Albert Park lake in South Melbourne. Melbourne's skyline is visible in the background under a mostly clear sky.

#SilentSunday #Australia

Photo of a dry floodplain along the path of the Goulburn river in Australia. The foreground is of dry land with scattered native grasses and fallen branches. On each side and in the far distance are eucalyptus trees. In the middle a body of muddy water is visible, the only left during the dry season. Above, an almost cloudless sky.

#SilentSunday #HongKong

A night scene of a wooden sailbot with red sails illuminated by artificial light. The boat is sailing across a body of water. In the background, across the water, the skyline of the city of Honk Kong (tall buildings and skyscrapers) is glowing with multi-coloured artificial lights.

OK, one of key features of our book on #Synchrotron Light is that it considers a broader context for synchrotron sources, by no means limited to particle accelerators. In the book we discuss three generalisations: 1. Synchrotron radiation is not exclusive to […] [Original post on aus.social]

Two Feynman diagram representing two equivalent processes in the electro-weak theory.

In the top diagram, an electron (drawn as a solid line with an arrow directed from left to right), emits a photon at the point P1. The photon is drawn as a squiggly line outgoing from P1 to the upper-right direction. The electron recoils from P1 toward the lower-right direction.

In the botton diagram there is the equivalent process whereby an electron emits a Z0 gauge boson at the point P2 and recoils towards the lower-right direction. The Z0 boson travels towards the upper left and eventually decays at the point P3 emitting two muons of opposite electric charge (denoted by solid lines) diverging from P3 towards the right direction.

Quite surprisingly, most of the properties of (classical) synchrotron radiation were worked out by G.A. Schott in1907--1912 in his dissertation work. Working in a 'pre-quantum' world, Schott wanted to explain the observed lines in the emission #spectra of atoms […] [Original post on aus.social]

The front page of the "London, Edinburgh and Dublin Philosophical Magazine and Journal of Science" dated February 1907. The page shows a scientific article by G.A. Schott titled "On the electron theory of matter and on radiation". The articles begins with the following words: "One of the most important problems of the Electron Theory of Matter is to account for the spectra emitted by the several elements; the solution of this problem, rather than of any other, seems likely to lead to the construction of a working model of the atom."

In a bit of shameless self-promotion, I'm proud to announce that I've a new book out! "Synchrotron Light: a Physics Journey from Laboratory to Cosmos", was written together with my co-author Prof. David Paganin and published by Oxford University Press. Target […] [Original post on aus.social]

The cover of the book "Synchrotron Light: A Physics Journey from Laboratory to Cosmos" by Daniele Pelliccia and David M. Paganin, to be published by Oxford University Press. The cover has an abstract background in blue/purple shades with diagonal white strikes in the top-right corner.

Prahran (Melbourne), #Australia #graffiti #UrbanArt

A colourful mural painted on the side of a building. The mural features abstract graffiti-style lettering and patterns in various bright colours like pink, yellow, and orange.
In the foreground of the image, there is an old, white car, parked on the side of the road.
