Things Have Changed

I’ve been busy with other things, but after taking a look today at various new things related to quantum gravity, I was struck by how much things have changed sociologically in that subject over the last few years. Back in … Continue reading ?

Extreme cold and shipwreck lead

Scientists have proven the concept of the CUORE experiment, which will study neutrinos with the world’s coldest detector and ancient lead. Scientists on an experiment in Italy are looking for a process so rare, it is thought to occur less than once every trillion, trillion years. Show More Summary

Slightly Belated Star Talk TV Thoughts

Neil deGrasse Tyson’s TV talk show had its debut Monday night on the National Geographic channel, something that’s very relevant to my interests. It airs after I go to bed, though, so I set the DVR to record it, and watched it Tuesday afternoon. Then I was too busy yesterday to write about it… Anyway,…

The greatest physics theorem you've never heard of

This concept's played a greater part in physics than relativity and quantum theory, so why has the great woman behind it not achieved Einstein's fame?

Italian neutrino experiment to move to the US

This article appeared in symmetry on April 22, 2015. Mysterious particles called neutrinos seem to come in three varieties. However, peculiar findings in experiments over the past two decades make scientists wonder if a fourth is lurking just out of sight. To help solve this mystery, a group of scientists spearheaded by Nobel laureate Carlo

A Quantum of Sunshine

It was nice and sunny this morning when I sat down at Starbucks to do some blogging, so I wrote a new Forbes post about the quantum physics that makes sunshine possible. This also brings in xkcd’s take on the fundamental forces, and even a little bit of SteelyKid. Sadly, it’s now grey and dreary,…

“Is There Something Mysterious About Math?”

When it rains, it pours: after not blogging for a month, I now have a second thing to blog about in as many days.  Aeon, an online magazine, asked me to write a short essay responding to the question above, so I did.  My essay is here.  Spoiler alert: my thesis is that yes, there’s […]

Italian neutrino experiment to move to the US

The world’s largest liquid-argon neutrino detector will help with the search for sterile neutrinos at Fermilab. Mysterious particles called neutrinos seem to come in three varieties. However, peculiar findings in experiments over the...Show More Summary

Two papers

Just to get myself back into the habit of blogging: For those of you who don’t read Lance’s and Bill’s blog, there was a pretty significant breakthrough in complexity theory announced last week.  (And yes, I’m now spending one of the two or so uses of the word “breakthrough” that I allow myself per year.)

Mu2e breaks ground on experiment

Scientists seek rare muon conversion that could signal new physics. This weekend, members of the Mu2e collaboration dug their shovels into the ground of Fermilab's Muon Campus for the experiment that will search for the direct conversion...Show More Summary

Mu2e breaks ground on experiment seeking new physics

This article appeared in Fermilab Today on April 21, 2015. This weekend, members of the Mu2e collaboration dug their shovels into the ground of Fermilab’s Muon Campus for the experiment that will search for the direct conversion of a muon into an electron in the hunt for new physics. For decades, the Standard Model has

In Case You Wondered…

Dear visitor who came here (perhaps) after visiting the panel I participated in on Saturday at the LA Times Festival of Books. ("Grasping the Ineffable: On Science and Health") What a fun discussion! Pity we ran out of time before we...Show More Summary

My Valuable Extra Phone

Back when we went to London for Worldcon (and then I went to Sweden for a workshop), I bought a smartphone in Heathrow thinking I could sell it back when I left. That turned out not to work the way we thought, but it’s served me well ever since as an e-reader. It can’t connect…

Festivities (I)

Love this picture posted by USC's Facebook page. (I really hope that we did not go over the heads of our - very patient - audience during the Festival of Books panel...) -cvj They don't give a photo credit, so I'm pointing you back to the posting here until I work it out.

The Real Access Problem with the Hugos

There has been a lot of stuff written in response to the Hugo award nomination mess, most of it stupid. Some of it is stupid to such an impressive degree that it actually makes me feel sympathetic toward people who I know are wrong about everything. One of the few exceptions is the long essay…

Festival Panel

Don't forget that this weekend is the fantastic LA Times Festival of Books! See my earlier post. Actually, I'll be on a panel at 3:00pm in Wallis Annenberg Hall entitled "Grasping the Ineffable: On Science and Health", with Pat Levitt and Elyn Saks, chaired by the Science writer KC Cole.

Antiprotons from AMS

This week the AMS collaboration released the long expected measurement of the cosmic ray antiproton spectrum. Antiprotons are produced in our galaxy in collisions of high-energy cosmic rays with interstellar matter, the so-called secondary production. Show More Summary

In Defense of Scientism and the Joys of Self-Publishing.

As long-time readers of Quantum Diaries know I have been publishing here for a number of years and this is my 85th and last post[1]. A couple of years ago, I collected the then current collection, titled it “In Defense of Scientism,” after the title of one of the essays, and sent it off to

Proto quantum computer inspired by Victorians gets a speed boost

A new approach has sped up a quantum device that exploits collisions between particles, signalling that the method may have yet more mileage in it
