Uncle Helium Gets Married
Physicists observe antihelium-4 nucleus, the heaviest antinucleus yet
[S]cientists with the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory have observed another state of antimatter for the first time: the antimatter helium-4 nucleus, which is the heaviest antinucleus observed so far.
Not Letting the Facts Get in the Way
A case of never letting the source spoil a good story
Of course, this is a problem that generalises well beyond science. Over and again, you read comment pieces that purport to be responding to an earlier piece, but distort the earlier arguments, or miss out the most important ones: they count on it being inconvenient for you to check. There’s also an interesting difference between different media: most bloggers have no institutional credibility, so they must build it by linking transparently and allowing you to double-check their work easily.
But more than anything, because linking to sources is such an easy thing to do and the motivations for avoiding links are so dubious, I’ve detected myself using a new rule of thumb: if you don’t link to primary sources, I just don’t trust you.
If I Did It
Several weeks ago we had an office discussion that eventually got around to xkcd and the fascination with ball pits, to pranks involving filling up a cubicle with balls or packing peanuts. The problem with such pranks, it was observed, is that balls are expensive and balls or peanuts take up the same volume ahead of time — storage is an issue. But balloons … they don’t suffer from this problem. You could fill a colleague’s office with balloons.
“That would be cool,” that colleague was heard to utter.
To me, such a statement is an invitation. It would be rude to not fill that person’s office with balloons, should such an opportunity arise, and I fear that someone might do it. So it got me thinking. How would one go about doing such a thing? (Not that I would do such a dastardly thing — I wouldn’t want to expose myself to a wrongful breath suit)
First thing would be to obtain a pump. Double-action, so it fills on both the up- and down-stroke.

When filling the balloons, I would use a balloon clip to speed things up (tying is such a pain) and would find that twisting the neck is important, otherwise the air would tend to quickly leak out.

Then, I would start filling the office. Maybe during lunch hour, or at odd times during the day (and staying late to ensure my real work was done). Get an idea of how many balloons I and any co-conspirators could fill. The progress after one day might look something like this

After four days, it might look something like this

I’ll bet with some help I could use up 200 12″ balloons and 122 (50+72) 17″ balloons, along with a few balloon-animal style balloons (which would be close to useless, since they take up so little volume). With that many, I’d probably notice that there is significant balloon-stink. And I would find the non-stick agent they use (probably cornstarch) to be really annoying after a while.
To be especially devious I might even fill some of the balloons with confetti, so that popping them all would become more of a challenge. I might be tempted to also fill some with helium, but they wouldn’t survive the weekend, so I wouldn’t bother. I’d probably find that about 10% of the balloons would be lost to defect and breakage, and would be amused by the occasional “boom” coming from the office. I’ll bet it would remind me of the episode of the Simpsons where Homer becomes the Beer Baron (Homer vs. the 18th Amendment), and his stills kept blowing up.
If I were to do such a thing.
Because People Could Die
Back when I was teaching in the Navy’s nuclear propulsion program, I saw that there was an foundational attitude towards operational systems: these are the rules — obey them. It is not up to you to decide that it’s OK to not follow them. And the unspoken undercurrent to that is because if you don’t, people could die. This applied to the reactor systems, because they were designed to work a certain way and had safeguards that assumed you were operating it according to procedure. The attitude was also present, as far as I could tell, to general shipboard operations. Most of my students were going to serve aboard submarines, and the potential for disaster is magnified by orders of magnitude when you are in a closed container some depth below the surface, and a loss of propulsion or breathable air could spell your doom. (Not that duty aboard a surface ship means tolerance for corner-cutting, either). That’s why they continually drill — practice your responses to emergency situations and do it right, because if you don’t, people could die. Commanding officers are used to orders being carried out, rather than getting “that’s not in my job description.” And you know what? The navy has a pretty good track record for a task that’s just a little dangerous. (As a side note, I can only imagine the frustration of the navy folk atop my org chart, dealing with a staff that is >90% civilian and who generally lack this ingrained response to following orders and rules without question*, and among whom are several people who do decide that a rule is silly and therefore will not be followed)
This attitude goes beyond the military. It’s why we have safety rules and building codes, and people who work within professions that have them, you will generally find a serious attitude toward such protocols. The people with experience do not relish putting their health or life at risk at the behest of someone looking for a shortcut. And usually a shortcut is a temptation for those who wish to save time and/or money, and for whom it means putting someone else at risk.
I was reminded of this when I read Millions saved in Japan by good engineering and government building codes. (The link title is a play on a tweet by Dave Ewing, who proclaimed that it was a headline you would not see.) And though some of the numbers are out of date (it was posted on the 12th, and the death toll is significantly larger), the idea is still valid. The Japanese have recognized the continual danger of earthquake and tsunami and instituted building codes to minimize the destruction, despite the fact that it costs more to do that. While such efforts did not (and probably cannot) result in no damage or loss of life, the devastation was far less than has occurred with weaker earthquakes elsewhere.
The difference is that Japan has made a commitment to earthquake-safe buildings, and had the money to carry out that commitment. Haiti lacked the money to implement strict construction standards and a government capable of compelling compliance. Builders and government regulators in the United States have the power and the resources to ensure Japanese standards of construction apply here, but my sense from living in California for 3 years is that we may lack the commitment needed to do this.
I think Josh is right about the US lacking the commitment — it’s just not how we do things here. We moan and wail about how damnably expensive regulation is, and how we should be free from government intrusion (curiously, I have yet to see any small-government proponents claim that the nuclear power industry is over-regulated). The question of how much money a regulation will cost is always asked, but the question of how many lives will be lost or saved does not seem to get the same attention. We bemoan the loss of life and note the monetary costs when a bridge or dam fails, but the money to inspect, repair and modify them isn’t always spent. There is a push to let businesses regulate themselves, to let “the market” take care if such things, except that “the market” doesn’t punish transgressors until after the fact, if at all. Action is taken, or not taken, for money, not because people could die. Prevention is usually invisible, which was the point behind the tweet, and too often we reward politicians for bold responses, not bold prevention.
* “without question” is not the same as “without grumbling.” Generally speaking (or Admirally speaking, since this is the navy) you grumble but do the task, and sailors are excellent grumblers.

Deaths per TWH by energy source
What is the worst kind of power plant disaster? Hint: It’s not nuclear.
The disaster in Tokyo is horrific, and we aren’t trying to say it isn’t a terrible situation. The question we’re trying to answer rationally here is whether nuclear power plant accidents cause more damage than other kinds of power plants. We’ve put together a list of five of the worst power plant disasters in recent history, measured by death toll, monetary damage, and regions affected. The lesson? The issue isn’t so much the kind of energy you use, but how you design the power plants that contain it.

Misplaced Angst
Your iPod is polluting China and L.A.—and Wyoming might be next
You may have been aware too that in manufacturing your electronic marvel, the Shenzhen plant emitted roughly 25 pounds of the greenhouse gas carbon dioxide. It’s even possible that you were aware of the 9-10 pounds of CO2 emitted in transporting the device to you from China.
Oh my GOD! 35 POUNDS of CO2 in getting my iPod delivered to me. That’s horrible!
Um, no, not really.
Bbbbut, 35 POUNDS!
Let’s look at that. Of 35 pounds (16 kg), about 9.5 lbs (a little over 4 kg) is Carbon. Two gallons of gasoline contain 11 pounds of Carbon. It sounds like a lot, but realize that driving 10,000 miles a year in a car that gets 25 mpg you dump 4 tons of CO2 into the atmosphere. Context matters.
Further, the blurb about China burning coal to generate the electricity to do the manufacturing needs to put in context as well. In the United States, the average person uses FOUR TIMES as much electricity as the average person in China. Add to that the China has been aggressively pursuing green energy — they already lead the US in wind energy generation, and are pushing forward in solar while we drag our feet. The US is not “greener than thou” and shifting the blame for pollution/CO2 distracts from the need to get our own house in order.
