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: Nobel Prize 2011 by an Israel Scientist! Wonderful Chemist!

Scientists from Israel won the Nobel Prize for chemistry thanks to a remarkable discovery. Scientists managed to break the old understand about the pattern of crystal-forming component. Understand the old saying that the crystal has a repeating pattern forming. However, this discovery succeeded in undermining understands it. It took years to understand Shechtman's new truth by scientists is recognized worldwide.



Physics Concept: Moon as Earth's Natural Satelite


Moon is shown as the beautiful circular light from the Earth. Therefore, in the past time, human realized that the earth is a holy thing. So many people have the great mythology about moon. Some of them call the moon as God, and any other mythology. This is happen because the moon just shown as far object that cannot be reached by human in that time. 


Physics Concept: Atmosphere and Weather


Atmosphere is the layer of air that surrounds the earth. The air is a gas object consisting of a variety of gases, dust, moisture and other particles. This will protect the earths from excessive solar radiation and meteor hit (the rocks) derived from space. In addition, the atmosphere is the medium for the cloud, due to the position of the Earth 32 ½ tilted to the plane of orbit, causing weather patterns are not the same as every part of the world long the year. Movement of air in the atmosphere sometimes also cause havoc such as hurricanes that hit many areas on the surface of this earth. Because of this atmosphere influence eventually evolved sciences such as climatology, meteorology and geophysics.

The atmosphere consists of layers of gas to a height of 80 km of gas composition in the atmosphere can be said uniform. In the dry state of the air composition is largely made up of:
Nitrogen                      78%
Oxygen                       21%
Carbon dioxide           0.03%
Noble gases                 0.936%
Water vapor and dust Uncertain

Physics Concept: The Theory of Relativity

    Frame of reference is the beginning of the emergence of the theory of Relativity. The theory developed by Albert Einstein was a result of his analysis of physical phenomena that have never discussed the existence of a universal reference frame. Frame of reference that is used there are two types, namely inert frame of reference and terms of reference are not inert.

    Frame of reference is not inert shells intended to accelerate. This reference frame used in the general theory of Relativity.
    Inert reference frame is a coordinate system relative to the physical measurements (e.g. mass, velocity, time, length, energy, momentum and so on). A universal reference frame is a system that moves with the speed and direction are fixed (without acceleration).
    Einstein's General Relativity Theory requires a curved space to describe the physical world is using mathematical theory of differential geometry and tensors to describe gravity and quite complicated. This theory has the same form for all observers, both for the observer who is engaged in an inert or frame of reference for the observer who is engaged in an accelerated frame of reference. In general Relativity, gravity is no longer a force (as in Newton's law of gravity) but is a consequence of the curvature of space-time. General relativity showed that the curvature of space-time is due to the presence of mass.

Physics Context: Nuclear Physics Explains UFO


After half a century of investigation, a nuclear physicist believes that the phenomenon of flying saucers or UFOs can be explained scientifically.



"Some UFOs are extraterrestrial spacecraft which is controlled intelligently. And this is the biggest story this century," said Stanton Friedman, a nuclear physicist, as reported by Foxnews.com, Thursday, June 10, 2010.

Stanton Friedman worked for 14 years as a nuclear physicist for such companies as General Electric, General Motors, Westinghouse, and Aerojet General Nucleonics.

Physics Context: Fire Rainbow

Atmospheric phenomenon was known as arc circum-horizon or Fire Rainbow (rainbow fire), will appear when the sun is high (more than 58 degrees above the horizon). Sunlight shone through straight and cirrus clouds, thus producing a kind of crystal slabs and formed hexagon prism effect. So it looks like a rainbow-shaped flame.

Physics Context: Ball Lightning is not a UFO! So?

Many studies have suggested that ball lightning is a form of discharge is varied and sustained within microseconds. Although many different observations in a field / space occurrence of ball lightning, but in principle all of which aim to provide a basic understanding that can be used as a comparison in explaining the process of ball lightning. In explanation, the Poisson equations are a method of approach that can provide an understanding of an equation of the electron and ion movement in explaining the occurrence of ball lightning.

Physics Context: Ice Wave! How did it? Who did it?

Physics Context: Have you ever heard "Ice Circle"?


When you see a strange circle on the surface of the river, do not rush to conclude that the UFO had just landed in river. Maybe what you see is the Ice Circle newly formed.

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.

Physics Context: Waterfall is usual. What about "fire fall"? Amazing!


KOMPAS.com - Looking at the waterfall may be the norm. However, what about "fire falls"? This is a unique phenomenon that can be seen at Horsetail Falls in Yosemite National Park, California. The fire was contained in the group plunged Sierra Nevada mountains, west of Lake Tahoe, having an altitude of 2,000 feet or approximately 600 meters.


"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. 



Physics Context: NAO Robots! They are able to express the humanies emotional!


KOMPAS.com - World Robotic Explorer Opening on Saturday (12.11.10) was enlivened by the presence of Nao robot, a humanoid robot that was produced by Aldebaran Robotics, a robot development company based in France.

What is Nao? Bruno Maisonnier, Nao Foundation CEO, said: "Nao is not an abbreviation. Nao could mean close to nanotechnology that is now a trend, it could also mean the brain or the light."


Classified as a humanoid robot, Nao will be able to demonstrate expression of humanity. For example, the robot is able to show emotion as simple as one year old children.


Nao also be able to perform various movements, like walking, dancing, sitting, standing, kicking and reaching a certain object. In addition, the robot is also able to turn his head towards a speaker or sound source.

Physics News: Einstein's Brain Was Stealed



A
lbert Einstein was the a genius scientist in 20th century. His imaginations, concept understandings, creativities, inovations and complex minds of physics was made the great discovery of modern physics. His postulate has been used to creating technology that requires the concept of modern physics like space lab, nuclear, photovoltaic, and so many others. These briliant idea of him was made the high curiousity of some scientist in that century about Einstein’s intelligent. The one manifestation of this curiousity was happened on a scientist that had a ambition to do a research of Einstein’s brain. This ambition is happened of a scientist that made an incident of The Stealing of Einstein’s Brain.
