Quantum Bullshit Detector, pretty much needed today I fear.

Exciting ***** moments in physics last 5 years (in order of discovery):

* Higgs particle

* Gravitational waves, including colliding black holes and neutron stars – might be 6 star 😉

* The M87 black hole image for sure!

All of them took a long time from idea -> experiment (50 and 100 years respectively)

In science in general:

* CRISPR-Cas genetic editing

* AI and deep learning, solving Go, Chess, and protein folding.

* Quantum technology: quantum computers, quantum internet etc.

Conclusion: it’s a golden era for science

Flee from the Mount Stupid, always!


Quantum to Cosmos:

Worth a visit, no doubt.

Multi-purpose silicon chip created for quantum information processing

The Bristol team has been using silicon photonic chips as a way to try to build quantum computing components on a large scale and today’s result, published in the journal Nature Photonics, demonstrates it is possible to fully control two qubits of information within a single integrated chip. This means any task that can be achieved with two qubits, can be programmed and realised with the device.

Source (CERN): Higgs boson comes out on top

New results from the ATLAS and CMS experiments at the Large Hadron Collider (LHC) reveal how strongly the Higgs boson interacts with the heaviest known elementary particle, the top quark.

Surely If I were in Los Angeles area I would try to go to the Caltech’s Beckman Auditorium to celebrate Richard Feynman’s 100th birthday. Relatives, friends, and top-notch colleagues will be there remembering Richard Feynman, one of the big theoretical physicists of the XX’s century, and hence, one of the giants of the human history.

Fascinating, two experimental setups that make quantum entanglement “visible (or nearly visible) to the naked eye”.

If you have one hour available, I think this lecture is a good homenage to Joe Polchinski who passed away a couple of days ago.

For people interested in this top theoretical physicist, check out e.g.:
