According to The Guardian,
It is, perhaps, a measure of just how powerful she has become: Angela Merkelnow appears to be influencing youth slang. The compilers of Germany’s most popular dictionary say that the verb “merkeln” is on track to become the most popular “youth word” of the year… The word is none-too flattering, meaning being indecisive, or failing to have an opinion on something – behaviour that Germans often attribute to Merkel.
They attribute this characteristic to quantum physics:
Merkel observers put the chancellor’s approach down to her training in quantum physics, which leads her to work a problem through step by step like an experiment, rather than trying to predict its outcome in advance.
What’s weird is, first of all, that she’s not particularly an expert on quantum physics. Her doctorate is in physical chemistry, and while it did involve quantum mechanics, it also involved many other tools and methods equally well. Second, the characteristics they describe have nothing to do with quantum physics. They’re simply attributes of an experimental scientist (though I would have thought that scientists are more typically accused of being dogmatic and inflexible, more than of being indecisive).
Surely, if you’re attributing someone’s indecision to their training in quantum physics you have to make some reference to “uncertainty” or “quantum superposition”. Merkel is Schrödinger’s Kanzlerin.
