something i learned today:
the ratio between the size of one digit of one of your fingers and the next digit of the same finger is roughly Φ, the golden ratio. Their lengths line up in an approximate way with sequential fibonacci numbers, because as the fibonacci sequence progresses the ratio between sequential numbers approaches Φ. i illustrated this in that image using an arbitrary unit of pixels and the grid in photoshop.
but the real cool part is that because of this, when you curl and uncurl your fingers, the path described by a fingertip is pretty close to a perfect golden spiral! what sweetly built machines we pilot over the earth
Alejandro Guijarro - Momentum (2010-12)
“The artist travelled to the great quantum mechanics institutions of the world and, using a large-format camera, photographed blackboards as he found them. Momentum displayed the photographs in life-size.
Before he walked into a lecture hall Guijarro had no idea what he might find. He began by recording the blackboard with the minimum of interference. No detail of the lecture hall was included, the blackboard frame was removed and we are left with a surface charged with abstract equations. Effectively these are documents. Yet once removed from their institutional beginnings the meaning evolves. The viewer begins to appreciate the equations for their line and form. Color comes into play and the waves created by the blackboard eraser suggest a vast landscape or galactic setting. The formulas appear to illustrate the worlds of Quantum Mechanics. What began as a precise lecture, a description of the physicist’s thought process, is transformed into a canvas open to any number of possibilities.”

i guess my teacher was right… math is art.
these would look great in the loft apartment i don’t have.
i’ll just have to like them from afar.

Look! In the Sky! It’s a cloud! It’s a number! It’s… the first 1000 digits of Pi?
On the afternoon of September 12, 2012, artist ISHKY, with Stamen Design, launched Pi in the Sky, a project that used skywriting to create quarter-mile tall digits at 10,000 feet over the San Francisco Bay Area. It took a team of five synchronized skywriters “equipped with dot-matrix technology” to create the first one-thousand numbers of the infinite order of pi (3.14159, etc.). The airplanes made a 100-mile loop around the Bay Area, which created a temporary piece that was 150 miles long. It was created as part of the 2012 ZERO1 Biennial.
There’s a Kickstarter for everything.
Did you know it was so complicated?
A follower recently asked me about the communications technology used to help maneuver the curiosity rover. Well here’s a part of how they did it.
In this picture of the antenna DSS-63 with a diameter of 70m (20 floor building) is pointing the Curiosity rover 8 hours before landing on the surface of Mars (Also pictured).
This antenna is located in Madrid and it is part of the Deep Space Network (DSN) property of NASA JPL. At the moment of the picture, the antenna was busy doing Ranging and Doppler measurements of the signals traveling from the spacecraft in order to calculate its position. At the end of this session the calculated position is radioed back to the Curiosity so it can make its EDL using only its IMU and radar.
