Ice Circle

Ice Circle or the circle of ice is a phenomenon that appears in the water that has a slow flow in a cold climate. The shape resembles a giant dish which consists of ice and rotates slowly on the surface of the water.

Fire Rainbow

Atmospheric phenomenon was known as arc circum-horizon or Fire Rainbow, will appear when the sun is high (more than 58 degrees above the horizon).

Fire Fall

"Fire fall" is basically a waterfall, but unique in that get sun exposure so the shimmering golden twilight. This incident is very rare and only a few days a year, usually in February, the sun will highlight a waterfall, creating an orange light like a flame skyline.

Fire Ball

"Fire Ball" an unexplained atmospheric electrical phenomenon. The term refers to reports of luminous, spherical objects which vary from pea-sized to several meters in diameter (Wikipedia).

NAO Robot

"NAO Robot" is an autonomous, programmable humanoid robot developed by Aldebaran Robotics, a French robotics company headquartered in Paris (Wikipedia).

NAO Robot

"Cavendish Experiment" was the first experiment to measure the force of gravity between masses in the laboratory[1] and the first to yield accurate values for the gravitational constant (Wikipedia).

Star Telescope

"Star telescope " A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century, using glass lenses. They found use in terrestrial applications and astronomy (Wikipedia).

Physics News: Scientists Researching the Memory of Bees

Honeybees can remember the scent of flowers they visit by allocating memory types differ in their small brains, the researchers suspected.

Professor Lesley Rogers from the University of New England in Armidale, Australia, and Professor Giorgio Vallortigara of the University of Trento in Italy this week to report their findings to the journal Plo ONE.

The researchers showed that the bee brain is divided into two parts with different functions in this case reminds us of the human brain.

Physics Context: Flying Technique of Swallow

Have you ever seen a tornado or vortex of the cyclone-shaft?  All the objects that are flying around the tornado will be brought into the rotation, such as a tornado sucked in the direction axis.  Why so?  Because the air pressure inside the tornado is smaller than the surrounding air pressure.  The difference in air pressure caused large enough to draw objects like oil drums, roofs, and even a buffalo into the vortex of a tornado.  So, what to do with birds swallow?  Was able to swallow flew through a tornado vortex?  Here's the story.

Physics Context: Black Hole

A black hole is a region of space whose gravitational force is so strong that nothing can escape from it. A black hole is invisible because it even traps light. The fundamental descriptions of black holes are based on equations in the theory of general relativity developed by the German-born physicist Albert Einstein. The theory was published in 1916.

Physics Context: Super Speed Computer Processor by Grafin Transistor

Know what your computer processor speed today?  Your notebook processor speed or current?  Know what the fastest computer processor speed today?  Apparently all is still in the figure Mega Hertz (MHz) or Giga Hertz (GHz).
Ever imagine what it's like using a super fast computer with a processor speed of 40 Terra Hertz (40,000 GHz)?

Physics News: Indonesian Become Champion of the 17th ICYS

DENPASAR, (AP) .- Indonesia managed to become the overall champion at the Scientific Research Competition Youth World Level The 17 or the 17th International Conference of Young Scientists (ICYS) held in Denpasar, Bali 12 to 17 April 2010.  The Indonesian team that competed in all areas of competition, ie Physics, Mathematics, Computers, and Ecology won seven gold medals, 1 silver medal and 3 bronze medals.

Physics Context: The Quake May Have to Change the Rotation of the Earth

Richard Gross, a geophysicist at NASA's Jet Propulsion Laboratory in California Machinery theorized that transfer large amounts of mass in the center of the Earth on the deadly earthquake on Sunday, December 26, 2004 and has accelerated the rotation of the Earth as much as 3 microseconds where 1 microsecond is one millionth of a second and move at 1  2:54 inches or centimeters from the axis.

Physics News: Asteroid may hit Earth in 2029

Chances are one in 300 if the 400-meter sized asteroid will hit Earth in 2029 but might be missed if the scientists managed to obtain additional data about the orbit.

Physics Context: Anomaly in the Law of Gravity

Propulsion Laboratory where physicists jet engine works have studied data from two Pioneer spacecraft 10 and 11 who had been flying for ten years of solar system.

Physics Context: Chemists Use Nanotechnology to Penetrate Plant Cell Walls

A team from Iowa State University plant scientists and materials chemists have successfully used nanotechnology to penetrate plant cell walls and simultaneously provide the genes and chemicals that trigger the expression with controlled precision.  their breakthrough brings nanotechnology to plant biology and agricultural biotechnology, creating a powerful new tool for targeted delivery into plant cells.

Physics Concept: Nanotechnology

Nanotechnology is a highly multidisciplinary field, ranging from applied physics, materials science, interface and colloid science, device physics, supra-molecular chemistry, self-duplicating machine and robotics, chemical engineering, mechanical engineering, biological engineering, food technology and electro techno.  The term nanotechnology comes from the Greek word "nano" meaning dwarf or midget.  In technical terms "nano" means objects that are so small in size billionth of a meter (10-9m).
