Education and “Internet Time”

I saw this link on techcrunch go by discussing the state of venture capital in the education sector. There is a general feeling, at least in the article, that when dealing with universities that things are not moving at internet speed: “The challenge is, in general, education is a pretty slow to move category, particularly […]

Sit down and relaxion

2 months agoAcademics / Physics : Resonaances

New ideas are rare in particle physics these days. Solutions to the naturalness problem of the Higgs mass are true collector's items. For these reasons, the new mechanism addressing the naturalness problem via cosmological relaxation have stirred a lot of interest in the community. Show More Summary

Summer Break

Heading out soon for summer vacation travels, this time to Ireland and France, back in about two weeks. While away comments will be shut off. My vacation will spare readers commentary on the rest of the Strings 2015 talks, which … Continue reading ?

So far, the Summer has not been as brutal in the garden as it was last year. Let's hope that continues. I think that late rain we had last month (or earlier this month?) helped my later planting get a good start too. This snap of a sunflower...Show More Summary

On Scientific Conferences, and Making Them Better

I’ve been doing a bunch of conferencing recently, what with DAMOP a few weeks ago and then Convergence last week. This prompted me to write up a couple of posts about conference-related things, which I posted over at Forbes. These were apparently a pretty bad fit for the folks reading over there, as they’ve gotten…

What can happen in 1 second?

The leap second added to time on 30 June 2015 got us thinking – some pretty big stuff only takes a second Read more: "Get ready for the leap second – it could be the last one ever"

Most Played Songs Meme

This went around a different corner of my social-media universe while I was off in Waterloo, away from my iTunes. I was curious about it, though, so looked at the contents of the “25 Most Played” playlist, and having done that, I might as well post them here (the number in parentheses is the number…

Celebrate gay marriage—and its 2065 equivalent

Yesterday was a historic day for the United States, and I was as delighted as everyone else I know.  I’ve supported gay marriage since the mid-1990s, when as a teenager, I read Andrew Hodges’ classic biography of Alan Turing, and burned with white-hot rage at Turing’s treatment.  In the world he was born into—our world, […]

Course Report: Intro Mechanics Spring 2015

I’ve been pretty quiet about educational matters of late, for the simple reason that I was too busy teaching to say much. The dust having settled a bit, though, I thought I would put some notes here about what I did this past term, and what worked. I had two sections of the introductory Newtonian…

Yesterday, an interesting thing happened while I was out in my neighbourhood walking my son for a good hour or more (covered, in a stroller - I was hoping he'd get some sleep), visiting various shops, running errands. Before describing it, I offer two bits of background information as (possibly relevant?) context. Show More Summary

My Week in Waterloo

I spent the last few days in Ontario, attending the Convergence meeting at the Perimeter Institute. This brought a bunch of Perimeter alumni and other big names together for a series of talks and discussions about the current state and future course of physics. My role at this was basically to impersonate a journalist, and…

Exploring dark energy with robots

The Dark Energy Spectroscopic Instrument will produce a 3-D space map using a ‘hive’ of robots. Five thousand pencil-shaped robots, densely nested in a metal hive, whir to life with a precise, dizzying choreography. Small U-shaped heads...Show More Summary

“Can Quantum Computing Reveal the True Meaning of Quantum Mechanics?”

I now have a 3500-word post on that question up at NOVA’s “Nature of Reality” blog.  If you’ve been reading Shtetl-Optimized religiously for the past decade (why?), there won’t be much new to you there, but if not, well, I hope you like it!  Comments are welcome, either here or there.  Thanks so much to Kate Becker at NOVA for […]

Speed Dating for Science!

Last night was amusing. I was at the YouTubeLA space with 6 other scientists from various fields, engaging with an audience of writers and other creators for YouTube, TV, film, etc. It was an event hosted by the Science and Entertainment...Show More Summary

Seeing in gamma rays

The latest sky maps produced by Fermi Gamma-ray Space Telescope combine seven years of observations. Maps from the Fermi Gamma-ray Space Telescope literally show the universe in a different light. Today Fermi’s Large Area Telescope (LAT)...Show More Summary

Bringing neutrino research back to India

The India-based Neutrino Observatory will provide a home base for Indian particle physicists. Pottipuram, a village in southern India, is mostly known for its farming. Goats graze on the mountains and fields yield modest harvests ofShow More Summary

Get ready for the leap second – it could be the last one ever

On Tuesday night the clocks will stand still at 23:59:60 to keep our time in sync with the universe. But does our high-speed world demand a new solution?

LARP completes first successful test of High-Luminosity LHC coil

This article appeared in Fermilab Today on June 22, 2015. Last month, a group collaborating across four national laboratories completed the first successful tests of a superconducting coil in preparation for the future high-luminosity upgrade of the Large Hadron Collider, or HL-LHC. These tests indicate that the magnet design may be adequate for its intended

Anomalies Revisited

Some of the talks at Strings 2015 have now appeared online, and one of them I found quite fascinating, Witten’s Anomalies Revisited. Some of his motivation comes from string perturbation theory and M-theory, but the questions he addresses are fundamental, … Continue reading ?

Convergence

Another conference that starts today is the Convergence conference at the Perimeter Institute. The concept is explained by Neil Turok here. His point of view is one I’m very much in sympathy with: Turok explains that the “large bandwagon” of … Continue reading ?
