Gold Coated Ants and MicrocogsThis is possibly one of the greatest “just because we can” things I have ever seen. For some inexplicable reason scientists decided to pose this ant with a miniature cogwheel. To get a good image of this using a scanning electron microscope the ant first had to be freeze dried and then covered in a thin layer of gold in order to stop a charge from building up as the specimen is bombarded with electrons. For science!

An Overview of Chaos TheoryIn its simplest form chaos theory simply describes a system that is very sensitive to initial conditions. That’s not so hard is it? The term is often used in reference to the butterfly effect which postulates that something so seemingly insignificant as a butterfly flapping its wings can generate a storm on the other side of the planet. While that may be a bit of an overstatement, many real life systems, including the weather, display chaotic behavior. The effect is best seen in a double pendulum system (a pendulum attached to the end of another pendulum) which generates the image above (a long exposure image tracked with LEDS). Small changes, such as changing the angle between the two pendulums when released, would generate a gratuitous amount of widely different pathways.Image source

What you’re looking at here is the first ever colour photograph created by Thomas Sutton using the technique outlined by James Clerk Maxwell who is most famous for his equations describing electric and magnetic fields. It was made using the fact that the brain fabricates all hues based upon the three colours red, green and blue. By using three filters to select for these colours and then projecting all of them at once onto a screen Maxwell was able to reproduce the exact hues and colours of the original scene. This is imaginatively called the Three Colour Process.

The subject matter for this picture was a tartan ribbon, but was deemed a failure by Maxwell as it failed to pick up much of the red or green of the original ribbon. The truly weird thing is that the chemicals used were completely insensitive to red, but it’s postulated that the “red” photographic plate actually picked up ultraviolet radiation.

Not satisfied with attaining a PhD in Theoretical Physics from Yerevan State University for research in the field of Quantum Chaos, he has also documented in astonishing detail the Human Eye and now, similiarly, the animal eye. What a wonderful thing. Included in this series are the eyes of Husky Dog, Horse, Snail, Fish, Iguana, Caiman, Nylus Crocodile and others.”Original Article

The Hidden Colors of Sudden Oak DeathThis pop-art style picture is an aerial image of a section of forest showing trees dying from Sudden Oak Death caused by the bacterium Phytopthora ramorum in the center surrounded by healthy trees. These images were taken by a special camera exploring the possibility of using aerial photography to identify diseased trees. The upper left image is what is seen to the human eye, while the upper right image shows an overlay of visual data and infrared data with diseased trees in purple. The bottom left image emphasizes the near-infrared spectrum that is typically reflected from healthy plants. Finally the bottom right image that looks like those crystal-form Christmas trees shows the subtleties in the spread of the disease. Cyan shows dead trees while pink with touches of cyan starting to appear shows infected trees that will soon succumb.

Taking a break from actual science to post a cool aerial shot of some geography. This is in fact a view of the Betsiboka River in Madagascar and shows the different colours caused by different sediments. Also it looks like some weird octopus or jelly fish.

Kirlain photography is a method of photographing the electrical discharge of various objects, the process involves placing said object upon a photographic plate and running a voltage across it. This outlines the subject, in this case a set of leaves, with a corona of electrical energy that is only visible on the plate.
