Looking through the julia code, I saw quite a bit of memory management, which did surprise me. Generally with Julia, you want to allocate memory, once, to avoid penalties of reallocating memory and gc. I pulled the code down, placed the da

The Majorana fermion was just observed and reported this past year. Fundamental physics. Foundational physics. No accelerators needed. Bose-Einstein condensates have been observed and used in a variety of situations. No accelerators neede

Well ... no. We have several interpretations of QM, one of which has been dominant for most of the last century. But the other interpretations have been getting deeper looks due to things that the current interpretation "hand waves&q

I personally find the entropy connection with information theory and black holes fascinating.

I'm sorry, but I disagree with the label "fundamental" here. One can observe anti-de Sitter spaces in superfluid systems. Is that not more "fundamental" than zoology of particles and their interactions? That has,

Non-sequitur. Quantum mechanics didn't require $10B (or whatever the equivalent would be in 1930-ish currency) to create. The "inventors" of QM were trying to explain measurements that were already made, quite inexpensively,

Superconducting magnets were in use well before their use in HEP colliders. FPGA computing was in use in industry well before it was in use in HEP colliders. Particle detectors have existed for more than 100 years. When was the first colli

I generally disagree with broad brush strokes of articles and books that make such cases. I find this to be a watered down variant on Phrenology[1], but rather than using physical skull measurements, people invoke the existence of two X ch

The issue is, quite literally, what is the opportunity cost of this expenditure. If that money could help create a pandemic mitigation framework that would enable us to collectively respond faster and better to outbreaks, which is better t

As a (non-practicing) physicist, I've always disliked the penchant of some in the HEP community to say what this article says. They (the HEP community) tends to equate physics with HEP physics. It's not. When this is pointed out

My daughter started in Art school at the university, then switched to Physics/Math. She is passionate about art, but found the environment hostile. She was welcomed with open arms in the physics, math, and engineering schools, and is

There are economic factors associated with being a primary educator. The pay, for lack of a better way to put it, sucks. This impacts men and women. My wife and I went through Physics grad school together. To say that the experience was

Not sure why you are getting downvoted over this. It is pretty close to what I observe. Express "wrongthink" and you will get banned. That should terrify everyone. As you don't know what rightthink and wrongthink are. They

I was at Joyent when we deplatformed some group. The vast majority of the company was for this action, based upon what they interpreted as "their values." Their values were not shared in whole across the entire company. Some of

I keep hearing stories about similar issues. Suddenly someone is terminated from a Google service for unknown reasons, without any possibility of reversing such decisions. This appears to be true of Twitter and others as well. From my vant

That's not a shallow dismissal. Fundamentally, what I read was a cohort size of 11. 1 died. No control group. No double blind (as no control group). There's no aspect of this that would be statistically distinguishable from noi

VCs were always 'risk' averse, though this manifested in odd behaviors. Such as the herd signal, whereby one investor decided to invest attracted more capital. One might argue that the signal indicated lower risk, but this runs a

I'd argue this is more of an issue with wayland than zoom. Wayland seems to break many things from what I've read. I use linuxmint, so largely, I don't run into these issues.

Having used zoom, teams, skype for business, webex, and many others ... zoom is the only one of these which just works. I'm on the con calls typically 5+ hours a day. Yes, it is soul crushing. Teams sorta works, though it often messe

I agree, CEOs that bought back stock should not have the option of a bailout. That was a self-enrichment strategy built upon cheap debt, and now it is time to pay the bill. Generally speaking, Boeing and others should not be bailed out.

I set up systems in 2009+ that had multiple IPs per phy, bonded, vlan, etc. on linux. I used the config files within the distro (mostly CentOS/RH then) to do this. Worked fine. I developed somewhat better inspection scripting to aug

I'd comment, but if I did, I'd likely exceed the boundaries of my own agreement with a different company.

Hrm ... I recall Pythonistas trashing Perl as line noise, and other languages as well, for many many years. I'm not saying its right, just that karma, sometimes, comes back into focus.

When you write idiomatic Julia ... not C in a Julia syntax, but actually leverage the native power of Julia, yeah, you write code differently.

In many ways, Julia is a better python than python, if only for the lack of the (quite insane in the 2000s) program structure by text formatting. That is a misfeature. Julia is fast out of the box. You don't need Julia + some-other-l

I saw "relativistic gravitational force between neutrinos" and red flags went up. I've not read the article, just the abstract. Doing a bit more of a look on the RLM, I found this[1] where they (mis)write the relation betwee
