In this podcast episode we ask if online virtual meetings are the future for physics conferences
I love Physics World Weekly Podcast | Coronavirus hits the conference calendar, physicists excel in ‘deep tech’ start-up challenge, remembering Freeman Dyson - Physics World Weekly Podcast, let's play it!
I'm on a podcast for a little bit. Haven't listened to it/myself yet though...
Benjamin Skuse on a No-Longer-Sacred Artifact
“On the outskirts of Paris, eight metres below ground in a climate-controlled vault, sits a 143-year-old platinum alloy cylinder. Standing just 39 mm tall, it has never been touched by human hands. Like a delicate Russian doll, the cylinder is caged inside three nested glass bells in a room that can be accessed only with three keys kept by three different people. Surrounding the mysterious object are 'the witnesses': six 'identical' cylinders cast from the same platinum alloy.
“Though preservation efforts rival those of the Turin Shroud, the cylinder is not a sacred religious object. It is the International Prototype Kilogram (IPK), the one and only true kilogram against which all others are measured. Housed in the Pavillon de Breteuil – home to the International Bureau of Weights and Measures (BIPM) – the IPK will soon lose its unique status and become a relic of a bygone age. It will then be as quaint as the International Prototype Metre (IPM) – a platinum alloy bar also housed at the BIPM – that served as the world’s official metre until 1960.”
Benjamin Skuse, SI gets a makeover
Entanglement and magic interact in ways that impact quantum algorithms and physical systems
magic… those incels have been playing too many video games
"To address this discrepancy, researchers introduced the concept of “magic”. Magic quantifies the non-Clifford resources necessary to prepare a quantum state and thus serves as a more nuanced measure of a state’s quantum computational power."
magic, you don’t need bullshit like "magic". mathematically the word is "remainder"
