I’ve got your missing links right here (9 July 2011) | Not Exactly Rocket Science
To much deserved fanfare, Bora Zivkovic launched the new Scientific American blog network, featuring 47 blogs and some of the best writers around. Several personal favourites are now on the site and demand your attention including Jennifer Ouellette, Eric Michael Johnson, Jennifer Frazer, Hannah Waters, Lucas Brouwers, Kevin Zelnio, Charles Choi, Christie Wilcox, Darren Naish, SciCurious, Jason Goldman and more. All of this prompts PZ Myers to declare that “Scienceblogs.com is dead“.
The big journalism story this week: the Guardian revealed that the News of the World hacked the voicemails of murdered girl Millie Dowler and deleted messages, prompting false hope in her parents and possibly perverting the course of justice. That was the first of several revelations that culminated in the paper ending its 168 year run, as a result of the ensuing scandal. Here’s as good a summary as you’ll get of the whole scandal by the man who broke the story: the awesome Nick Davies. The Guardian has predictably the best coverage of the continuing story.

Summer Travels – Part 1 | Cosmic Variance
Like many physicists, I spend a reasonable portion of the summer months traveling, delivering talks at conferences and workshops, and taking the opportunity to meet with colleagues and gain first-hand experience of the range of research being done in my field. For me, this began a couple of hours after my classes ended for the semester (congratulations to my General Relativity class, all of whom did very well at the end of the day), when I headed off to California to hang out with Sean for a few days and to give the Caltech physics colloquium.
I always enjoy visiting Caltech, and I find colloquia particularly fun talks to deliver, since they provide the opportunity to explain what’s going on at the frontiers of the field to physicists who spend most of their time working in their own, different areas. But this talk was particularly exciting to give, because of the location. I hadn’t realized, but the Caltech physics colloquia take place in a rather old lecture hall (201 E. Bridge) in which I was told Richard Feynman delivered his renowned lectures on physics. This part of Caltech is about to undergo a round of renovations, which meant that this was probably my last chance to speak in the same place that Feynman did – a wonderful experience. With most academic travel, the main payback from a trip like this is the chance to develop some new ideas with one’s collaborators. This time was no exception, and Sean, a student of his and I started discussions about a new dark matter idea that I’ll attempt to blog about here should it come to anything.
After a week back in Philadelphia, I was on a plane once more, this time for a short hop to my old stomping grounds in Cleveland, to take part in a workshop on gravity being held at Case Western Reserve University. The last decade or so have seen a resurgence of efforts to seek a sensible way in which General Relativity (GR) might be modified, either in ways that might yield new physics of the early universe, or in a manner that might explain phenomena at late times. The main original impetus for this work has been the possibility that the phenomenon of cosmic acceleration might be signaling a modification of gravity on the largest scales. However, among many researchers the current thrust is to gain a comprehensive understanding of the ways in which gravity may differ from GR, and at what scales one might expect any allowed modifications to appear.
It is, in fact, an extremely tricky proposition to modify GR, with almost any idea one might think of running into trouble either with established tests of the theory within the solar system, or with serious theoretical inconsistencies such as the appearance of particles with negative energies, known as ghosts. Many of the more interesting ideas involve models arising from extra dimensions, which have led not only to interesting modified gravity models, but also to new ideas about field theories in four dimensions, that I will discuss in another post soon. The gravity workshop focused on many of these new ideas, and, as often happens at small intense meetings, I left with lots of new ideas about my own work.
In June, I left for a lightning trip to Brazil, to speak at the very first meeting of the whole of the Brazilian Physical Society. This conference was held in the beautiful location of Iguassu Falls. Although I was, unfortunately, too ill from a flu I had caught to be able to travel to the falls themselves, I was lucky enough to see them from the air a couple of times. I will clearly have to go back! The meeting had several thousand people, and it was clear that Brazilian physics is undergoing a period of rapid expansion, something it is heartening to see given the pressures science is facing in many other parts of the world. One of the highlights was an event launching the new South American branch of the International Center for Theoretical Physics (ICTP). The ICTP, in Trieste, Italy, was founded in 1964 by Abdus Salam, with the goal of providing educating scientists from developing countries. Their new branch, in Sao Paulo, will be directed by Nathan Berkovitz and should extend the great work of the original. It’ll be interested to see how this endeavor develops – I wish them all the best.
I’d intended three days in Brazil, but ended up there for an extra twenty-four hours because the airport at Iguassa Falls was closed for a day by particulates from the Chilean volcano. I get delayed many times every year and find myself cursing airlines (I’d missed an important meeting in Cambridge a few weeks earlier thanks to USAir), but it’s hard to be furious at a volcano. The people at the Brazilian Physical society were wonderfully helpful and I’d like to thank them as publically as I can for taking such good care of us, dealing with our hotel rooms, and getting us rebooked on new flights.
Now I’m back to work, taking a few weeks without travel and trying to get new projects up and running, while finishing writing up a few papers before the new semester creeps up on me.

Working with NASA | Bad Astronomy
Did you know NASA collects 4 terabytes of data each day? And that a lot of this data is available to the public?
My friend Chris Pirillo interviewed Nick Skytland from NASA’s Open Government Initiative, and they talk about what NASA does beyond launching rockets:
Pretty cool. NASA does a lot of stuff… so of course the House of Representatives is talking about massively cutting it back. Incidentally, since writing that post, Senator Barbara Mikulski (D-MD) is gathering her forces to block canceling the James Webb Space Telescope program. I sent her a note thanking her, and hopefully the Senate can reign in the House’s political bluster.
And speaking of all this, with the successful launch of Atlantis, if you have Google Earth you can track the location of the Orbiter! Pretty cool. Also, as usual, Heavens-Above.com will allow you to predict the times when Atlantis and the Space Station are visible from your location.

Car Review: 2011 Honda Accord Crosstour
The Honda Accord Crosstour is a strange duck, and it's hard to know what to make of it. What is it trying to be? A poor man's Panamera? A dumbed-down SUV or a puffed-up hatchback? Its bulbous rear styling is arresting, to say the least: my little sister called the Crosstour "flying space ban

Do You Safeguard Your Hearing?
Engineers and tech people know the benefits of using earplugs around noisy equipment to avoid hearing damage, and many use them at home and play. Others don't, which probably accounts for 50 million Americans that suffer from tinnitus. Loud noises — from not only machinery, but also earphones,
FDA’s New Sunscreen Rules Help Make Beach Vacations Safer
Sunscreen labels should hopefuly be less confusing now.
Finally! About two weeks ago, the FDA announced that they are introducing new sunscreen rules that will hopefully prevent more sun burns and sun cancers. I’ve been purchasing broad spectrum sunscreens of at least SPF 30 for awhile, but it’s always been frustrating to me that all sunscreens in the US do not offer this protection. European countries have made this sort of protection standard for years, and it’s encouraging that our country is finally getting on the bandwagon. It’s not difficult to find sunscreens here that offer UVB protection, but finding broad spectrum sunscreens that shield sunbathers from harmful UVA rays is not always as easy. Sometimes I’ve had to resort to buying “baby sunscreen” to make sure I get both types of protection. Whatever works!
The new rules will go into full effect next summer (2012), so read learn and apply (no pun intended) the rules before heading out for your next Florida beach vacation. Here’s a quick rundown of how the rules will change things:
1. The term “broad spectrum” will not be able to be used on sunscreens that don’t provide the minimum standard of UVA protection.
2. All sunscreens will continue to have an SPF rating, but for products that DON’T have the broad-spectrum rating, the SPF rating will rate ONLY the UVB protection.
3. Higher SPF numbers on broad-spectrum sunscreens will mean more protection against BOTH UVB and UVA
4. Here’s a very helpful one — sunscreens will have to put in writing how many minutes after water exposure or sweating the sunscreen will still be effective (i.e. 30 minutes or 50 minutes). Those that are not water resistant will have to say so on the box.
5. NO sunscreen will be allowed to say that it is wateraPROOF (Hurray! This has always been a pet peeve of mine.) Saying a sunscreen is water RESISTANT is fine, so long as the sunscreen tells you how long you have before you have to re-apply.
Here’s to safe sun worshiping! Remember — you are NOT protected from the sun by the ocean. You’re actually much more exposed when in and around the ocean. I would show you pictures from personal experience to prove this, but I don’t want to ruin anyone’s day.
Follow the new rules so you don't look like this!

Huntingon Beach, CA – US Open of Surfing Contest July 30-August 7
A surfer on Huntington Beach
Surf’s up! Surfing aficionados already know about this, but everyone else might not — a fantastic surfing festival takes place every year in Huntington Beach, CA. The US Open of Surfing is the largest competition in the world and the festival draws tens of thousands of people every year. If you plan to be in the LA area around July 30-August 7, definitely check it out. It’s one thing to watch surfing on TV, but it’s an entirely different experience to watch it live. Some of the world’s best surfers attend this competition, and they’re truly amazing to watch. You can even admire how some of the younger surfers handle the waves in the junior competitions. It’s all a lot harder than it looks!
Why Huntington Beach? As blogger Barbara Weibel points out, Huntington Beach has been named the Surf Capitol of the USA, and for good reason – there are a variety of waves to attempt, from softly rounded baby ones good for beginners to the double breaking waves usually only surfed by the pros. Surfing a wave is a life-changing experience for many; the feeling of the water’s energy beneath your board is magical and addictive.
After a long weekend of absorbing some surfing culture, you could even learn how to construct some sand castles on the beach — Dig It! is a company that specializes in instructing people how to build sand castles – pretty neat, right?
