Science, Mathematics and Vampires

 Histoire des vampires et des spectres malfaisans avec un examen du vampirisme, 1820

A surprisingly large number of academic studies—as in, more than one—have applied mathematical modeling to the concept of human-vampire co-existence. Using the depiction of bloodsuckers in various forms of media, from Bram Stoker's Dracula to True Blood, these papers look at whether Earth's vampire population would inevitably annihilate humanity, and, if so, how long it would take.

This article of Atlas Obscura presents an interesting history of mathematics dealing with the transylvanian problem of renewable resources. Great lecture!

Delay causes syncronizity between Neurons and Hipsters

Female hipster with bike by Lorena Cupcake

The Neuroscientist Jonathan Touboul does research on hipster-alike-neurons, i.e. "they fire when every neuron around them is quiet; or they fall silent when every neuron around them is chattering." (I myself was not aware of this definition of hipster and feel quite uncomfortable hip right now, but that will pass.) And he noticed some rather interesting similarities between societies involving hipsters in general and brains involving hipster neurons in particular:

But members of society do not have immediate knowledge of cultural trends. Neither do neurons immediately recognize what other neurons are up to.

So the important term here is: immediate. There is a delay - and due to the delay, there comes syncronizity in the reaction: This is why hipsters look all the same. Read more on the mathematics behind it on io9: A Mathematical Model Explains Why All Hipsters Look The Same. Or, with a broadend focus on entrepreneurs at NoStartupHipsters: What do Neurons, Hipsters and Entrepreneurs have in common?

Sehr lesenswerter Artikel über Johnny Königs Schlagzeugvertonte Version von Edmund Stoibers "10 Minuten" Rede.

Noch mal zum Beispiel aus dem Wohltemperierten Klavier. Wenn man es zusammenbringt mit Fouriers Entdeckung, wird einem klar, was für ein jeweils unfassbar komplexes Gebilde diese nur fünfstimmigen Akkorde sind. Und man versteht besser, warum sie zwar nicht mit Worten, aber mit Noten beschrieben werden können. Aber ist nicht auch das wunderbar oder wenigstens verwunderlich, dass wir diese Komplexität fühlen können?
