coloured Wifi radiowaves

August 13, 2013

An artist helped a astrobiologist to produce a series of illustrations representing Wifi radiowaves if they were visible.

The artist: Nickolay Lamm

The astrobiologist : Browing Vogel

Wi-Fi radiowaves can be represented as colored circles radiating from the source.

A ‘normal’ Wi-Fi field is generally spherical and can range from 65 to 100 feet (20 meters to 30 meters, approximately)

the king (of contemporary art) is naked and it is time to claim it? really?

August 6, 2013

a month ago, Luc Ferry (a French philosopher and former education minister) denounced in Le Figaro “these temples of ignorance that are the regional contemporary art funds (FRAC)” and, in general, public subsidies in favour of contemporary art.

“The truth, he wrote, is that state aid often allows vulgar impostures to be considered as masterpieces.”

He continued further:

– some artists repeat and rehash ad nauseam, one hundred years later, but with no courage and thanks to taxpayer money, what Marcel Duchamp had already done a thousand times at a time when, at least, he ran the risk to “shock the bourgeois”.

– Let’s face it: if these disgusting things were in the lobby of my building, I would ask my caretaker to call urgently the City public services to get rid of it.

– Those who want to buy this kind of artwork are free to do so, it is their choice, but, please, may them do it with their own money! Some snobbish and ignorant people could agree to buy this junk for a golden price, but it is unacceptable that they pay it out of “our” pockets on behalf of their aberrant conception of culture. Reading these lines, the “Red Guards of contemporary art” will cry fascism. Whatever, the king is naked and it is time to claim it.

while the countryside sweats during a heat wave, cooling itself through evaporation, the city just bakes

August 6, 2013

Cities can be anywhere from 2 to 20 degrees Fahrenheit hotter than nearby countryside, due to what’s known as the “urban heat island” effect

Baltimore case study:

Researchers compared temperatures downtown to those near the Baltimore/Washington International Airport—a residential, half-forested area.

Using modeling software, they found that temperatures downtown weren’t simply a sum of the urban heat island and the heat wave—they were three and a half degrees hotter than that

Urban areas are carpeted in asphalt and concrete, which don’t hold water like soil and vegetation do. So while the countryside sweats during a heat wave, cooling itself through evaporation, the city just bakes. But researchers say there’s a simple solution to beat the heat: install green roofs, and plant some trees
