Hi friends, according to astronomers, a solar eclipse occurs tomorrow, on 21 May 2012. This is the first solar eclipse occurred in 2012 fren. Want to know what and how the eclipse of the sun, let's see the article about the eclipse of the sun and the moon follows.
The process of solar and lunar eclipses
The eclipse is the sun or the moon closed suddenly. The eclipse can be divided into two, namely the lunar eclipse and a solar eclipse.
Lunar eclipse occurs because sunlight toward the moon blocked the earth. Because sunlight leads to the earth, the earth was formed behind the shadow, the shadow of total (umbra) and a dim shadow (penumbra). Total lunar eclipse occurs when the moon is in the umbra region. If the moon is in the penumbra, the eclipse happens is that a lunar eclipse or eclipse parisal part. Lunar eclipse occurs at night time. The occurrence of a lunar eclipse can be seen in the following figure. If we look at the picture below, a lunar eclipse occurs when the position of the Sun - Earth - Moon are in a line.
Now, if a solar eclipse occurs when moon passes between the Earth and the Sun. Earth's umbra in the area will experience a total solar eclipse, while those in the Earth's penumbra will experience partial solar eclipses (partial). Solar eclipse occurs in the daytime. The process of solar eclipse can be seen in the following figure. We see that the position of the Sun - Moon - Earth is in a straight line.
Terms Higgs Boson increasingly popular today .. why do not you? What the heck is the Higgs Boson? Kok also said people Higgs boson is a particle of God?
What is the Higgs Boson, God Particle
Higgs Boson became famous for his newly discovered by a CERN scientist named Peter Higgs, who announced on July 4, 2012 days ago. Boson is the name for the particles tend to gather with like particles themselves. Higgs boson is a boson that also interacts with other particles making up the material and cause other particles making up matter has mass (aka weight).
Higgs Boson also spelled as God for Higgs Boson particle that causes other particles making up matter has mass, because the matter has mass can therefore form everything including planets, stars and the universe.
Discovery of the Higgs Boson
What is the Higgs Boson, God Particle
Here is the core of the standard model, which was developed in the early 1970s: the whole universe is made up of 12 different particles of matter and four styles [source: European Organization for Nuclear Research]. Among them 12 particles, you'll find six quarks and six leptons. Quarks make up protons and neutrons, while family members leptons including electrons and electron neutrinos, neutral associates charged. Scientists think that leptons and quarks are separated, that you can not separate them into smaller particles. Along with all of the particles, the standard model also recognizes four forces: gravity, electromagnetic, strong and weak.
Without the Higgs field and the Higgs Boson, which is composed of atomic particles can not be formed. Similarly, the chemical bonds and the objects of the universe.
Hi friends, have often played to the beach or not? if ever, would you ever seen the receding water lau, so it looks sprawling sand beaches, or any time you see the beach where the water is getting up almost covering the entire sand beach, the ocean is called the water was high tide. Let us see how the process of ebb and flow of sea water is ..
Occurrence Process Tidal Sea
As you discussed earlier, the earth revolves around the sun, while the moon revolves around the earth. In addition, the earth and the moon also rotates on its axis. Due gerakangerakan the position of the sun, earth and moon are always changing. Changes in these positions affect the level of sea water on the surface of the earth, commonly called high tide and low tide.
Tides and tides occur because of the force of gravity by the sun and the moon to the earth. Note the figure below (low tide = ebb, high tide = pairs)
Sea water in the surface of the earth when the earth high tide is in line or face the moon or sun. Though the Earth-sun distance of about 375 times the Earth-moon distance, but due to approximately 27 million solar masses in mass, therefore by the gravitational influence of the sun on sea water still visible, which is about half the force of gravity by the moon.
Rising tide of sea water there are only a few centimeters, but there are approximately 20 meters (maximum 6 storey building), for example in Canada. In Indonesia, the highest high tide of about 2-3 meters.
Objects that utilizes the properties of light are called optical instruments. Optical devices such as magnifying glass, cameras, microscopes, binoculars, and OHP. What are the usefulness of optical instruments such? Consider the following explanation!
1. magnifying glass
Lup is a magnifying glass. Loop consists of a convex lens. Small objects will look great when viewed with a magnifying glass. You can make a simple loop.
2. camera
The camera is an optical instrument that records the shadow of the object. The camera is used to photograph objects up close. However, the camera with lens distance photos, can capture objects located so far.
How does the camera work? The camera has a convex lens. When we took a photo of an object, the object lens cast a shadow on the film. The shadow is real and inverted. Furthermore, the film is released from the camera. The film brought to the photo shop to be processed and printed on photo paper.
How to make a sharp image formed? When photographing, we have to adjust the lens. The lens can be brought forward or pushed back with a regulator. In automatic cameras, the location of the lens is set automatically.
3. microscope
Object optical microscope is used to view very small objects (not visible). For example, bacteria, fungi, or other microscopic objects.
4. Overhead Projector (OHP)
Overhead Projector is a device for projecting images or text on the screen. How does the OHP? Wishing projected image must be photocopied onto plastic transparencies used. Plastics contain images placed on the glass. Then, transparencies lit from below. Rays transmitted to the projector head. Well, head projector will form a shadow on the screen.
5. periscope
Periscope telescope with a mirror is flat. Used on a submarine periscope to see objects on the surface of the water.
Hi mother .. how are you? longer care for infants age 9 10 months ya know? Aged 9-10 is peraliahn age Makananan Complementary feeding (MP-ASI). After enjoying the fine-textured soft porridge and gruel strain rougher textured, now the baby is ready to know the food team. The texture of the food is grown close to the texture of food. only, the texture made smaller - by chopped - and more flabby. At this stage, babies begin to recognize the food delivered to the family (table food). The habit of giving finger food at earlier ages, can be continued at this age.
