On today’s date, September 18th, Leon Foucault was born. Well-noted for his demonstration of the Foucault Pendulum, which was conceived as a simple experiment to show the rotation of the Earth, Foucault also devised an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope.
Happy 195th birthday, Monsieur Foucault!

Autumn equinox is arriving on September 23, 2014 at 2:29 (UTC). You can check the exact time in your area from here!

The autumn equinox is when the Earth has almost no tilt on its axis in regards to the sun. This means that both hemispheres of the Earth receive approximately the same amount of sunlight. You’ll notice that on equinox days, night and day are almost equal in length! 

Get ready for sweater weather and foliage!

Aye-aye is one of the strangest looking primates. They can only be found in the north-eastern parts of Madagascar. They are nocturnal and usually at the altitude above 700 meters of rain forest trees.

It has specifically designed middle finger which is used for extraction of food from trunks, braches and hard shells. Aye-aye taps a branch with its finger and listens if there is any sound of moving insects or larvae inside. If the movement is detected, aye-aye will make a hole with sharp teeth and use its middle digit to scoop the prey.

The ancient legends of Malagasy considered it the symbol of death due to its scary looks and eerie call. They believe that if the long pointed finger is pointed to any person, death befalls him/her. This leads people to kill aye-ayes on sight. Aye-aye is listed as nearly threatened species with 1000 left on the wild  and it is currently under protection.

Terrformation of Mars: A New Look
We look at Mars now as a forgotten Red Planet that almost seems barren and life-less judging from our available images and study of it. But study shows Mars was once as ecologically prosperous as our own Earth. But what happened to all of its waters? Better yet why is it so dry and lacking any plants? Once the abundance of oxygen left and the waters froze over or dried off the planet became what it is today. But what if we can in a way reactivate’ Mars? Welcome to Mars, Terraformed’.
About Terraforming
Transforming Mars will be a long and complicated process. But this is exactly the type of subject that interests space researchers like Christopher McKay of NASA Ames Research Center. First, greenhouse gases, like chlorofluorocarbons that contribute to the growing ozone layer on Earth, will be released into the atmosphere. This traps the heat from the Sun and raises the surface temperature by an average of 4 degrees Celsius. In order to achieve this, factories would manufacture chlorofluorocarbons derived from the air and soil. A single factory would require the power equivalent of a large nuclear power plant.
The increasing temperature would vaporize some of the carbon dioxide in the south polar cap. Introducing carbon dioxide into the atmosphere would produce additional warming, melting more of the polar cap until it has been vaporized completely. This would produce an average temperature rise of 70 degrees Celsius.
With the temperature this high, ice will start melting, providing the water needed to sustain life. This water would raise the atmospheric pressure to the equivalent of some mountaintops. While this would be a survivable level, it may still require the use of an oxygen mask. The next step, which may take up to several centuries, would be to plant trees that thrive on carbon dioxide and produce oxygen.

NASA: Terraforming Mars
Terraforming is the process of transforming a hostile environment into one suitable for human life. Being that Mars is the most Earth-like planet, it is the best candidate for terraforming. Once just the subject of science fiction novels, it is now becoming a viable research area. The famed astronomer and Pulitzer prize winner, Carl Sagan, says that there is enormous promise in the search for ancient life on Mars. If life was once sustainable on Mars, it is important to know what caused Mars to evolve into the cold and lifeless planet it is today. With this knowledge, we can terraform Mars by reversing the process.
NASA scientists believe that it is technologically possible at the present time to create considerable global climate changes, allowing humans to live on Mars. But this will not be by any means an easy task. Raising the atmospheric pressure and surface temperature alone could be achieved in a few decades.
This research has strong environmental implications for Earth. What researchers are trying to do involves global warming, a sort of greenhouse effect on the cold planet Mars. Scientists may be able to test their hypotheses about global warming in their attempts to elevate Mars’ surface temperature. Likewise, once theories, they may be applied to our own planet in an attempt to reverse environmental damage done by pollution and deforestation.

600 Million Years and Counting…

I was pretty bored so I decided to make some GIFs of the last 600 million years of our planet’s plate tectonics.

The first GIF is a global mollewide projection. The second one is of the Colorado Plateau and the North American Southwest. The next GIF is of the entire formation of the North American Continent. The fourth GIF is of geologic and tectonic evolution of Europe. And finally the last one is the same as the first except in rectangular format.

I obtained the images from Global Paleogeography and them compiled them one by one into Photoshop with the end result being the above GIFs.

How ocean dust makes rain clouds
When storm clouds form over the ocean they’re drawing that moisture into the atmosphere to form clouds.  At that point it takes many water vapor molecules to freeze and bond with one another to fall from the sky, but how does this bonding process start?  
It begins with tiny particles of organic matter such as parts of cells of dead organisms that the water vapor can bond to (as ice). Scientists at UC San Diego now theorize that these particles get into the air from waves in the ocean crashing into one another.
However not all of these particles are organic.  For example, pollution particles can gather ice, but since they’re much smaller in size and reflective the ice tends to melt before it can get heavy enough to fall back to the ground.

Rosetta rondezvouzed with Comet 67P/Churyumov-Gerasimenko. Now we wait for the landing of the Philae lander.

“After 10 years, five months and four days travelling towards our destination, looping around the Sun five times and clocking up 6.4 billion kilometres, we are delighted to announce finally ‘we are here’,” says Jean-Jacques Dordain, ESA’s Director General.

“Europe’s Rosetta is now the first spacecraft in history to rendezvous with a comet, a major highlight in exploring our origins. Discoveries can start.” (via The Register)

Zoom Into a Microchip

It is absolutely crazy how tiny we can make things today.

What we’re seeing here is a standard microchip, older though in principle the same as modern cell phone chip.

At the micro level we’re dealing with this comparison:

"A micron is 1 millionth of a meter, 10-6 or 10-3 of a millimeter. Very tiny. It is abbreviated with the greek letter for M, or the mu."

It takes 100,000 Microns to equal about 4 inches and toward the end of the set we’re in the 1 micron range.

Sir Albert Einstein once said ”After a certain high level of technical skill is achieved, science and art tend to coalesce in aesthetics, plasticity, and form. The greatest scientists are artists as well.”  And I think that string art is one of the artworks of mathematics. Also, the calculations of string art  are really interesting.

Here is the menthod to find the intersection envelope for string art ideas:  Find the intersiction envelope (on plus.maths.org).  Also, we can extend the menthod in the case the line intersects the x axis at a certain point t.  It’s function  y_t(x), is o at t, and c-t at 0.
