Gerard 't Hooft @gthooft on Nature's bookkeeping system: where the degrees of freedom are. (h/t +Sabine Hossenfelder)
http://arxiv.org/abs/1605.00027
Abstract: Establishing how one should describe and study natures fundamental degrees of freedom is a notoriously difficult problem. It is tempting to assume that the number of bits (or qubits) needed in a given Planckian 3-volume, or perhaps 2-volume, is a fixed finite number, but this ansatz ...

Interesting read, thanks for the pointer. Too far outside my arena for me to contribute

My chat with some of the young minds who will soon be leading the world.
http://www.preposterousuniverse.com/blog/2016/04/25/youthful-brilliance/
A couple of weeks ago I visited the Texas A&M Physics and Engineering Festival. It was a busy trip — I gave a physics colloquium and a philosophy colloquium as well as a public talk ̵…

Buckets of raw data (well, 300 terabytes) from particle collisions have been released to the public by CERN.
http://gizmodo.com/cern-has-released-300-terabytes-of-collider-data-to-the-1772642139
Yesterday, the European Organization for Nuclear Research (CERN) dropped a staggering amount of raw data from the Large Hadron Collider on the internet for anyone to use: 300 terabytes worth.

Ah, good. At my current download speed, that will take a mere 13 months. Now, where to store it …

I would like to ask a question for, which I couldn't find a reasonable answer...I hope you could you could give me a genuine reply. E=mc2 or E=mn, according to this theory ;energy cannot be created nor destroyed but can be transformed from one State to another then how did energy come into existence without its creation.

Physicists are cautiously excited over a possible new particle at the LHC. Hybrid pop/technical explanation by +Matthew Buckley. http://www.physicsmatt.com/blog/2016/3/18/tdu3j18n86e01bd4a8l8u5flqdifce
The first part of this is a non-specialist description of the results of Moriond concerning the diphoton anomaly. About halfway through it will transition into a more technical discussion, including new plots I've made giving my theorist-level combinations of the data shown.

A deep dive into looking for new physics at the LHC (1st of 8 parts), by +Matthew Buckley at the Boston Review.
http://bostonreview.net/books-ideas/matthew-buckley-search-new-physics-cern
Anomalous collision events observed in Run 2 of CERN's Large Hadron Collider in 2015 may point to new physics beyond the Standard Model. Image courtesy of CERN. In February, I spent a few days at CERN, the European Organization for Nuclear Research. I spoke with physicists who devote themselves ...

The always-interesting Scott Aaronson on quantum mechanics, computers, gravity, utopia, and hard problems.
http://blogs.scientificamerican.com/cross-check/scott-aaronson-answers-every-ridiculously-big-question-i-throw-at-him/ …
Quantum-computer whiz riffs on simulated universes, the Singularity, unified theories, P/NP, the mind-body problem, free will, why there’s something rather than nothing, and more.

Lots of FBI/DHS spy flights over our house in LA, but I presume they're just checking out Dodgers games.

America is being watched from above. Government surveillance planes routinely circle over most major cities — but usually take the weekends off.

Physicists like to crash into other fields and ruffle feathers. Sometimes - not always - in a useful way.
http://undark.org/article/collaboration-and-tribalism-in-science/
When physicists and mathematicians venture into the social sciences, new discoveries await — but a lot of bickering and mistrust must be overcome first.

Physicist at Caltech. Master of time and space.
Introduction
I think about things that are smaller than atoms and/or bigger than galaxies.  Everything in between scares me.

Links on right will lead you to awesome things to read and think about.
