Physics News: Nobel Prize 2011 by an Israel Scientist! Wonderful Chemist!
10:01 PM
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
6:40 AM
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
6:24 AM
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
5:52 AM
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.
