Wisteria Hysteria

Dutch wireless disease?

Faced with the prospect of funding cuts from the new anti-intellectual government (“We don’t pay you to think, Mister Scientist!”), apparently someone at Wageningen University’s PR office has decided their results need to make more waves.

The university’s press release on their website is unfortunately only in Dutch, but in it they say that while observing young ash trees growing for three months, close proximity to six wireless routers seemed to cause discoloration and death of leaves. They then go on to say [translation mine],

Although the effects were observed using various sources of radiation and various trees, the researchers think it desirable to repeat the experiment, preferably during a longer period and on a larger scale.

This is code for “Our results were not statistically significant,” which in layman’s terms means “It might or might not be true, but we proved jack.” Now this research has the potential for far-reaching consequences in our modern society that depends on wireless internet and other sorts of electromagnetic waves, and the subject is also a touchy one, about which many people have a strong opinion which is totally unsupported by facts.

Let me state here once and for all that I don’t know the facts either. I tend to start out skeptical of these “studies” because of all the nonsense floating around, but like any good skeptic, I am open to being convinced by sound science. Several serious mistakes indicate, however, that while the as yet unpublished research may be sound, the press release doesn’t even come close:

  • Mistake #1. Sending out a press release before the experiment was finished, apparently. What if this premature conclusion is disproved when the experiment is repeated over longer periods and with more trees, as the researchers say they need to do?
  • Mistake #2. Misrepresenting collaborating parties in the press release. Only the city of Alphen is mentioned in this version of the press release, at whose request (and presumably, on whose dime) the research was carried out. However, other news items also list Delft University and the independent research lab TNO as parties in the research. That indicates to me that they must have been mentioned in an earlier version of the press release. Turns out, TNO issued a statement on their website explicitly distancing themselves from the conclusions! Let me assure you, this does not happen lightly in science.
  • Mistake #3. Including numbers in the press release to inflate its importance, without explaining what they mean so that readers can understand.

Let me elaborate a little on Mistake #3, since numbers are important in this game. The exact words are [again, translation mine]:

…frequencies varying from 2412 to 2472 MHz, and a power of 100 mW EIRP at 50 cm distance.

So this just means that they used wireless routers, transmitting at 2.4 GHz, and placed them half a meter away from the trees. The frequency “variation” here means nothing. The researchers didn’t vary anything, those frequencies are just the standard channels used by 802.11b and 802.11g wireless. Why didn’t they test 5 GHz, which is also a common frequency used by wireless routers? Couldn’t they afford more than six routers?

I also had to look up the abbreviation EIRP, which stands for equivalent isotropically radiated power. This is too technical for me to get into in this post (although if you’re curious I’d be happy to explain it) which means it had no business being in a press release for the public. Also, it makes no sense to quote the EIRP in this case, so I’m guessing the PR office just got it off the side of the box the router came in. For nerds who know what I’m talking about, the power the tree is actually exposed to, depends not only on the distance to the source (and it falls off as 1/r²) but also on the surface the tree presents to the source!

The figure of 100 mW, besides being dubious, also means nothing to the average reader when taken out of context. Let me illustrate: a 100 mW green laser beam will blind you if you look into it. It might sting you if you stick your hand into it, and it might burn paper, all depending on how tightly it’s focused. But a regular 40-watt lightbulb, which radiates both light and heat, lights up your room nicely and harmlessly, despite radiating four hundred times as much power as the laser beam.

You stay the hell away from my baby, you internet tree-murderer! (By blaackhawk, freely reusable, from sxc.hu)

You stay the hell away from my baby, you internet tree-murderer!

All this has led to a spate of news articles with titles like “Wireless internet makes plants sick!” The irresponsibility exhibited here just astounds me. Hippies everywhere are going to don their tinfoil hats, and mobile phone users are going to be subjected to the kind of crusade that smokers have already had to face: “Put away that phone, you irresponsible jerk!” concerned mothers will scream at us. “Your secondhand radiation is giving my kid cancer!” Of course I’m exaggerating, but the damage is already done.

The worst example of this is Spits’ (a freely distributed newspaper, i.e. you get what you pay for) take on the article: you might as well stop reading when you see the giant radioactivity signs in the photo! Conflating ionizing nuclear radiation with non-ionizing electromagnetic radiation is pure fear-mongering, because they are as similar as Santa Claus and Parmesan cheese. If you do read beyond the photograph, bravely risking the loss of several IQ points, you see that Spits can’t even avoid contradicting themselves within the three-paragraph extent of the article! [translation mine.]

Whether radiation is really the cause of these phenomena, did not become clear in the study. […] In the study, the possibility that ultrafine particulates caused the phenomena was not ruled out. In any case, it is certain that the dead leaves and stunted growth were caused by radiation, according to the researchers.

The last sentence is also an outright lie, if I’m to believe the university’s press release. All because some PR monkey or fame-crazy researcher couldn’t wait for conclusive, publishable results and decided to fan the flames of the public’s fear instead. Sorry people, but when the results are not conclusive, that means the results are not conclusive. That’s the way science works. Suck it up and deal with it.

Revelations about the Rapture

My good friend Diederik Jekel, who has actually been the subject of a post in this space recently, approached me with the idea of doing a guest post. I often enjoy Diederik’s opinions on separating good science from bad science and we have had many stimulating discussions on the subject in the past. Since Diederik is looking to be an actual science writer (as opposed to an armchair dilettante like myself) I am honored to host this essay, or “rant” as he calls it.

* * *

The past day I have stumbled a few times upon an article by Elizabeth Young. A few times because it has been published at multiple sites, a few of which have continuously tried to open pop-ups telling me I was a winner of a grand prize. Putting this all aside, I was intrigued by this article because it was combining the words ‘rapture’ and the ‘Large Hadron Collider’. Two things which I am very interested in. The article speaks of mass torture being inflicted on Mother Earth by doing experiments inside the LHC. A true genocide performed on innocent atoms and protons who are obviously neglected by the Geneva Convention. The international human rights Magna Carta is invoked and the question is posed, if these rights are applicable to us humans, why does it not apply to Mother Earth?

Now my intonation might come across as cynical but I am truly not here to bash the article as perhaps a non-believer of the Gaia theory. I find it is very productive and useful in a discussion or policy to perceive the earth and her constituents as a living organism which must be cared for and nurtured. Even if it is done so as a selfish act whose only goal is to keep our species alive. So, addressing ethical dilemmas, which are often overlooked in the pursuit of scientific discovery, is something which can only be encouraged and applauded.

That being said, a few things about the article annoyed me, so much even that I found it necessary to say something on behalf of the physicists who are, according to this article, for all intents and purposes, callous, sociopathic monsters. This discussion is difficult though, because of the religious undertone in the article. It does not make sense to throw just scientific arguments against it. In the end you either believe in Gaia or you don’t. You believe in God or you don’t, and many scientists do actually. The scientific vs. religious debate is one which is often fought wrongly, because both sides have their own set of rules and try to convince the other side with their own set. It is like a Brit trying to convince a Dutch person it is dangerous to drive on the right side of the road. It might be perfectly valid in the construct of the British rules, but the Dutch guy will have serious trepidations about following his advice. So you can only debate with the Dutch guy if you use the Dutch traffic codes as arguments.

Crashing and smashing

Which brings me to the first point. In the article a graphic description is given of how atoms and protons collide in a fashion which would not be very pleasant to us humans. We would not like to be crashed into one another at nearly the speed of light. Why are we scientists then so arrogant in assuming this is OK for particles? I was always taught in religion classes in school that the Lord works in mysterious ways and that it is very presumptuous to assume that you know God’s plan.

Two things I know for a fact. One is that the earth is constantly bombarded by particles which have billions of times more energy than the ones we can create inside the LHC. These particles are generated in supernova explosions, rotating black holes and colliding galaxies. Processes which are incredibly more violent than we can possibly create here on earth. Nature seems to be fine with this, because she has been doing this for eons.

Another fact is that Brookhaven National Laboratory has claimed to have created the same kind of soup which the LHC wants to create. This new phase of matter is called quark-gluon plasma and like the three phases of water (ice, liquid and vapor) it is just another phase of matter. When you heat ice, it becomes water. When you heat water, it becomes a gas and if you were to heat lead atoms to trillions of degrees, it should become a quark-gluon plasma. So this has been done before and it shows that with extreme pressure and extreme temperatures, you get this weird state of matter.

To the best of physicists’ knowledge, there was something called a big bang, and only a fraction after the point of creation the universe was extremely dense and extremely hot. Gradually the universe expanded, which cooled everything and made it less dense. Precisely as predicted, this state will come about when you heat matter to enormous temperatures and this is what happens inside the LHC. It is, pun intended, a giant space heater. A nice hint towards the correctness of the big bang theory.

So if Nature is doing the same thing on her own on a massive scale, and that by just increasing pressure and temperature we find this incredibly beautiful substance called quark-gluon plasma, who are we to say: “This is something Nature finds unpleasant.”

All particles and forces around us were born inside this soup of quarks and gluons. Everything we see around us today, from a beautiful sunset, to this rant from a physicist, to all my wonderful friends, have originated from this ooze. This is our genesis and this is what physicists are trying to understand. Elizabeth Young quotes the Bible a lot as a justification for her side of the story. But in doing so she is trying to prevent us from understanding the origin of everything in our own scientific, empirical, and experimentally verified way.

So she claims to know all about God and Mother Earth and denies me my right to understand where we are coming from. What makes her such an expert? This is difficult to find out, because all information about the author (except her name) is about her husband. Do not get me wrong, her husband seems like a sensible, heroic and wonderful human being, but I have absolutely no credentials of the author herself. Oh, this is not entirely true, she is a Hollywood screenwriter. Besides that she will not tell the reader what makes her an expert.

Why do you care so much, you may wonder. Why are you whining about this? Fair and valid questions. The problem is that because she explains some things in scientific terms it seems that she knows what she is saying. If you throw big numbers and impressive terms at readers, they tend to see that person as an expert. Something which is common practice in pseudo-science. I am emphatically not claiming she is a pseudo-scientist here to dupe the masses. I am saying this to clear up why I am so annoyed by this article. People take it at face value because it is written nicely and has technical aspects to it, so as a reader why check it out further. How could you be critical of this, if you are not familiar with the subject?

Scientific details

A few scientific details I would like to clarify. The first argument she makes is the mass electrocution of the earth by the LHC. There are many more things happening daily on earth which cause a lot more electric energy than the LHC. I will come to that later and give an example. But first I must address something she keeps claiming:

Each time the LHC is fired, God, the Planet, Gaea, our Mother Earth is violently shocked with 3,500,000,000,000 volts of electricity.

I believe that she gets this number from the fact that particles are accelerated to an energy of 3.5 TeV or tera-electron volts. This is the quoted number up there. What physicists mean is the following: the particles inside the accelerator have the same amount of energy as an electron would have if we were to put it inside a potential difference (think battery) of 3,500,000,000,000 volts (think very large battery). This is a ridiculously large number. For if we were to make such a field, we would generate incredible lightning storms. Think of it this way, if you have a potential difference of 30,000 volts, you will get lightning of about 1 cm long. So having 60,000 volts gives you 2 cm long lightning and so on. This 3.5 TV gives you lightning of more than 1100 kilometers long! So this is to put the ridiculous number into context. Something else must be going on here.

Luckily we don’t have to accelerate particles with electric fields, we use big magnets. We only use this archaic measurement unit because it is convenient. You can even use lasers to accelerate particles, and that has even less to do with electricity. To make it even more strange, I can calculate how much electron volts worth of energy I have, when traveling inside my car at 80 km/h. It is a staggering 1.2 × 1023 eV, or to put it in context, 35 billion times more energy is in me traveling at that speed, than the LHC puts in its particles. The thing is I am also very much more heavy than a proton, so to put that amount of energy in one proton is very impressive. So not much zapping is going on because we do not use these electric fields.

Let us look at other sources which are electrocuting the earth. The earth’s entire magnetic field is created by extremely large electric currents flowing inside the earth’s core. Another electrocution source is lightning. Annually there are 16 million lightning storms, containing hundreds of bolts and each average bolt produces 500 megajoules of energy. 500 megajoules (a single bolt) in the weird electron volt unit gives 3 × 1027 electron volts!!! Which does not even have an official name because it is so big. It would be 3000 yotta-electron volts and is the equivalent of 857 trillion times the energy the LHC puts in her particles. And this is just one lightning bolt. So if the earth does not like electricity, it should stop making so much of it.

So much more energy is contained in lightning storms and in the earth’s core than the LHC can ever produce. And even so, the LHC does not generate this energy by using electricity, it does this by using magnets (which run on electricity, but this is not zapped straight into the earth.)

She goes on to use some other numbers, which are very questionable to say the least, but I don’t want to bore the reader with more he-said-she-said on math.

Pointless

Then comes the part where she says the LHC is all pointless because:

Whatever the outcome, the LHC will not be the final word in physics experimentation.

I find this unbelievable. So if it is not perfect, we should not do it at all? I am very glad she did not live during the caveman era, where man was trying to invent fire and she would say, “Why bother? It tends to go out and I might burn myself.” I believe the first aeroplane flight lasted about 10 seconds?

The endnotes finally are questionable to say the least and many quotes are used out of context but what I find utterly annoying is that she posts a phone number of a scientist online which you must call after reading her story, asking him to stop the experiment. I wonder if I should post her number here, so people can call her to explain what they think of her story. It is a spam-inducing breach of privacy.

One final quote:

But let me tell you this. I have proof these scientists may be several wires short of a working plug. Before they began their descent into scientific instability, these people actually made a rap video.

So as an extra argument for not trusting the hundreds of scientists who have worked their (pardon my French) asses off, she refers to a humorous video a few employees have made in an effort to make a particle accelerator a bit more comprehensible. Many people are afraid of this device, because of people like Elizabeth Young, who instead of trying to understand, try to scare the hell out of normal citizens. Including friends and family of mine who are, understandably so, worried.

The rap video was a joke. If scientists cannot be trusted when they try to make their work fun and relatable, then we are about to create very boring and annoying physicists. Scientists cannot use media such as video and rap songs to relate a more informal message? Then I ask you, Hollywood screenwriter Elizabeth Young, do you really want to link credibility to popular culture? Especially if these people made the rap video while getting their PhD in physics?

Illegal Were Folon’s!

The American elections are coming up tomorrow, which for me means completing an absentee ballot. I actually like this, since I can sit down and Google all the candidates at my leisure before voting, to make sure they’re not KKK members. One resource that I often use is vote411.org, which is sponsored by the League of Women Voters, a nonpartisan organization.

They send out questionnaires to every candidate for every elected office on every ballot, interviewing them on the relevant issues, which they then reprint on their website; you can even compare two candidates’ answers side by side. This is an amazing (and free) service. I rely on it to help me form an opinion about Maryland politics, since I’m registered to vote there.

There were four candidates for the US Senate on the ballot: a Democrat, a Republican, a Green candidate, and one from the Constitution Party. I would have thought that the Constitution Party was a recent consequence of the Tea Party, since every third word out of a Tea Partier’s mouth is “constitution”, but apparently it’s been around for ten years. Anyway, this Constitution candidate, Richard Shawver, answered the interview questions so incompetently that I truly don’t understand how he was able to string enough coherent sentences together to get on the ballot. For your reading pleasure, I reproduce the interview in full below [the links to the sections of the US Constitution are mine]:

QUALIFICATIONS: What are your qualifications for this office?

Richard Shawver: Article 1 Section 3 I believe in the constitution, want to keep this country a repubic.

BUDGET: What methods would you support to address the federal budget deficit?

Richard Shawver: Article 1 Section 8 Congress must obey thier oath.

FOSSIL FUELS: What should be done at the federal level to reduce our use of and dependence on fossil fuels?

Richard Shawver: Hydroelectric plants, clean burning coal plants.

IMMIGRATION: What changes, if any, do you support in regard to immigration policy?

Richard Shawver: Article 1 Section 8 Illegal were folon’s, could not become citizens.

CORPORATIONS/ELECTIONS: What do you think is the proper role of corporations in elections?

Richard Shawver: There no proper role.

EDUCATION: What role should the federal government play in public education?

Richard Shawver: None, its the states role.

SECURITY: What are the most important steps towards assuring the short- and long-term security of our country?

Richard Shawver: Article 1 Section 8

First of all, it’s obvious that writing coherent English must be an elitist policy designed by the Obama administration to give furriners an unfair edge over red-blooded Americans — wait, what? I don’t like to nitpick, but there is at least one spelling, grammar, or factual error in every answer, except the last one which isn’t even trying to be a sentence!

For example, I just love his stance on immigration. “ILLEGAL WERE FOLON’S!” is such a pithy slogan, it should be the new battle cry of Blondie and the Freedom Party as they lead the Netherlands back into the Dark Ages, cheered on by the neo-nazi English Defence League. They could print it on their flags. What are folon’s? That’s the beauty of it, nobody knows. My best guess is “felons”.

My favorite part, though, is that he wants to keep the country a “repubic”. I think it’s only fitting that if America is in the throes of repuberty, then who else but hormone-fueled brats should lead her.

Now my only worry is whether to be relieved that these people can’t possibly be taken seriously, or scared that they’re taken seriously enough to get this far. This is why I implore you, if you are one of those inhabitants of this world with the right to vote in the United States on Tuesday, to do at least a minimum amount of research. Watching smear ads on TV doesn’t count.
