Posts about the variety of science and their (assumed) knowledge.

Killing fuss

Killing fuss

In ‚Dying for some quiet: The truth about noise pollution‚ in the NewScientist they state that

«…the WHO’s findings suggest that long-term exposure to traffic noise may account for 3 per cent of deaths from ischaemic heart disease in Europe – typically heart attacks.»

In Europa alone probably half a million lifeyears are lost anually.

Killing fussNothing new are the facts that chronical niose pollution cause sleep disorder, hardness of hearing and learning disorders.

But really interesting is this:

A Swedish survey in Munich has shown a 25 % advancement of childrens long-term memory in th area of the airport Riem, after it was closed. Just impressive is the fact of a memory decline in the same degree in the area of the new Munich airport since it started operation.

So, what do we learn? Wearing ear muffs should be obligatory… 😐

industry and greenhouse gases

English (deutsch siehe unten)

If you thought it would be nice to have mediterranean temperatures in middle Europe by two more degrees Celsius in 2025, you must know that there is a good chance we’d have an increase of four degrees that year. And with it the dryness of nord Africa.

You ask why? Particulate matter might decrease the effect of greenhouse gases by its half, Nowadays, with all the particle filters, we’ll eventually get a nice burn in the future – simple, isn’t it?

Watch this BBC-documentation on YouTube and spread the word:

Global Dimming
(edit: Updated the videolinks)

Deutsch

Wer dachte, es wäre hübsch, in Mitteleuropa Mittelmeerklima zu haben, indem es 2 Grad wärmer wird, muss damit rechnen, dass es bis dann 4 Grad wärmer geworden ist. Und damit hier so trocken wie in Nordafrika.

Wie das gehen soll? Feinstaub in der Atmosphäre dürfte den Effekt der Treibhausgase um die Hälfte dämpfen. Mit den heutigen Partikelfiltern werden wir uns vielleicht einen netten Sonnenbrand einfangen.

Guck Dir dazu diese BBC-Doku auf YouTube:

The Power of Ten

The Power of Ten

Power of TenToday was a beautiful day and I was out by the river the first time this year with my Lapsteel playing. Looking at the water, this old movie «Power of ten» (YouTube video, 9 min.) from 1977 came to my mind. Read the details on wikipedia.

Well, this is now 30 years old, so I did some googling and found some more interesting, newer things. First, there’s a newer version of something similar: the Cosmic Voyage (YouTube, 4 min.) from 1996. This is unfortunately only the part of the journey similar to the former Power of Ten, I couldn’t find the whole movie, which is also described on Wikipedia.

Here’s also a slideshow-version from this idea to show the cosmos. I found even a version from the famous Simpsons animation series 🙂 .

There’s also a very interesting dissertation from astrophysicist Mike Norman on Google video (56 min). He takes you on an unprecedented journey across space and time to witness the formation of galaxies and cosmic structure as well as the formation of one of the first stars to shine in the universe.

His dissertation features also this by far the best animated virtual journey (YouTube, ca. 4 min.), calculated with accurate data from the actual cosmic science. So it’s up to date with data and computer rendering technique. Here are some screenshots (click for bigger versions, threy’re the best resolution I could get):

Orion and Horsehead NebulaThe journey will start at our solar system and the first impressing step is the Orion Nebula (right), 1000 light-years away, with the Horsehead Nebula (middle) in the background.

Our MilkywayWe then turn around to see a fictive picture of our own home galaxy, the Milkyway. Fictive because we still cannot shoot a picture of our galaxy… 😉 .

M-33 and the Andromeda galaxyThen we will pass through the galaxy M-33 (right) towards the giant Andromeda galaxy with the blue outskirts (top left). In the middle another star forming Nebula in M-33, like the Orion Nebula, but much larger. We’re about 1 million light-years away from home.

Virgo ClusterWhat looks like a couple of stars is actually the Virgo Cluster, about 28 mio light-years away, our local cluster of galaxies. Each white dot is a whole galaxy and the destination of this animated journey.

So, finally, if you look at the sky next time, try to imagine the 28 million light-years distance to our nearest galaxy cluster, which is only one of all them out there…

Die These

Machen junge Männer Krieg?

Gunnar Heinsohns wilde Thesen – und eine Berliner Studie zur Weltbevölkerung (von Reiner Klingholz)

Der amerikanische Geheimdienst CIA publizierte im Jahr 1995 das Papier Demografische Hintergründe für ethnische Konflikte. Darin ging es um die Frage, ob rasches Bevölkerungswachstum zu politischer Instabilität führen kann. Denn dieses erwirkt zwangsläufig einen youth bulge, eine Beule in der demografischen Kurve, einen Ãœberhang an jungen Menschen, die keinen Platz in der Gesellschaft finden. Die Studie kam zu dem Ergebnis, dass Mord und Totschlag drohen, sobald die Altersgruppe der 15- bis 24-Jährigen einen Anteil von 20 Prozent an der Gesamtbevölkerung übersteigt.

Der Spekulant

Der Spekulant

(sorry, all german)

Eine sehr interessante Arbeit habe ich auf www.derspekulant.info gefunden. Wer schon immer mal wissen wollte,

  • wie es sich verhält, wenn Gott ein Auto wäre und ein Mystiker, ein Wissenschaftler, ein Priester und ein Skeptiker darin Platz nehmen, oder
  • wie lange ein Affe auf einer Schreibmaschine tippen muss, bis der erste Einzeller entsteht, oder
  • wie die Evolution sich verhält, wenn Sony die Firma „Leben“ und der Mensch ihr Walk Man wäre,

sollte sich unbedingt die Zeit nehmen, diese Arbeit zu lesen.

Der Spekulant nähert sich auf unterhaltsame Weise in einfacher Sprache und simpler Logik dem Sinn des Lebens.

Viel Spass beim Lesen!
