El Patrón de los Números Primos: Prime Number Patterns. By Jason Davies.

El Patrón de los Números Primos: Prime Number Patterns

For each natural number n, we draw a periodic curve starting from the origin, intersecting the x-axis at n and its multiples. The prime numbers are those that have been intersected by only two curves: the prime number itself and one. Below the currently highlighted number, we also show its sum of divisors σ(n), and its aliquot sum s(n) = σ(n) - n, which indicate whether the number is prime, deficient, perfect or abundant. Based on Sobre el patrón de los números primos by Omar E. Pol. A Rough Mix: Brian Eno & Jennifer Jacquet An Edge Conversation. ENO: What I'm working on at the moment is a rough mix of a piece of music for a totem pole.

A Rough Mix: Brian Eno & Jennifer Jacquet An Edge Conversation

Usually one is asked to do music for films, but this is for a totem poll, and it's Jenifer's totem pole. It's a shame totem, in fact, Jennifer should tell you about it. JACQUET: I'm interested in how we make six billion people get along. And one way that we can do that is through shame, which is a really traditional way of getting people to adhere to social norms. So in the beginning, in the Garden of Eden, there was no shame, right? Adam and Eve, who were naked and felt exposed, had to cover themselves. The idea of nakedness, which you can't really see in this, but the idea of being naked is central to the notion of shame, the idea of being exposed. This was a pole raised in Sitka, Alaska in 1940. Shame poles were actually one of many type of totem poles, which were very important to the gardens of native communities along Northwest Coast.

So here's a really famous Tlinget Nation shame pole. IFTF_SR-1454A_FutureofScience_Map_lg.jpg (JPEG-Grafik, 1998x1332 Pixel) Was Sie schon immer über sich wissen wollten. I'm starting to think that the Left might actually be right. A Web Designer on Fukushima. By Oliver Reichenstein I’m not a nuclear expert.

A Web Designer on Fukushima

I am a 40-year-old Swiss web designer, with a degree in philosophy, living in Tokyo. And I’m a father of a two-year-old boy. I was kind of nonchalant about nuclear energy so far, but not anymore. For obvious reasons. As far as I can see some claim that the next generation of safe nuclear power plants will solve all problems; other people believe that only clean energy can save us from doom. All the power plants I’ve seen so far look quite uglyIn my world engineering is a matter of compromise, not perfectionIt’s usually not bad technology but bad practice that causes trouble The Good the Bad and the Ugly The Good The web is based on pretty good technology. I’m not saying that the web is an alternative to nuclear energy — I’m not that confused. The Bad Of course, I am not saying that there is no “bad technology”. The lack of thought is a problem as old as humanity. The Ugly The Use of Thought Thinking is hard work. Applied Science and Truth.
