Blue Moon

A miracle in the sky happened on 31 Dec 2009. The blue moon brightened up more on that night for the excitement of all the people. Though it is mentioned as blue moon the moon was not in blue color. According to the Indians, if the occurrence of the full moon is happened second time in a month, it is called as the Blue Moon. Actually in a year the full moon appears for 12 times but sometimes, it appears 13 times for every 2 to 3 years. This incident happened on December 2^nd and again this took place on 31^st of this month. All this information is passed on by the Science Popularization Association of Communication and Educators which is one of the important organizations for the special researches. In general, the moon appears blue in color when the sky is covered with a lot of dust and snow. But this process is totally different from this idea of getting the blue moon when it is covered by dust or snow. According to the special research center, it takes nearly 29.53 days to form a full moon which in terms can be called as one month. By this we can say that for every one month one full moon appears. But the moon which is left for the whole year forms as a second moon after 2 to 3 years which is called as the Blue Moon. After this formation of the blue moon on 31^st again it happens on November 21, 2010 and August 21, 2010. So it is going to be a great experience for the people on 31^st to watch this wonder which happens after many years.

Blinking Star

The stars, planets and sub planets in the space will be in the circular shape only. But during night times, the moon in the sky appears round in shape and all the stars are blinking. The reason behind this is when the light which comes from the stars travels through various densities of the air and undergoes refraction. Just because of this misplacement, the stars keep blinking. The Moon is not a shining planet of its own. Due to the reflection of light on the moon and the moon being closure to the earth, the light does not undergo much refraction and thus appears circular in shape. The reason for the stars blinking during night times in the sky is the Atmospheric refraction.

Refraction

The term refraction is defined as the bending of light as it passes from one type of material into another. Because light travels at different speeds in the two materials, it changes its speed at the boundary of the two materials. If a beam of light hits this boundary at an angle, then light hitting the side first will be forced to slow down or speed up before light on the other side hits the new material. This causes the beam to bend, or refract, at the boundary.
Suppose we were to place a coin in a glass of water. The light bouncing off the coin underwater, for instance, would have to first travel through the water and then the air to reach an observer's eye. At the boundary, it gets refracted and reaches the observer's eye, thus appearing to be slightly raised.



In the pencil case, the pencil is placed at a specific angle and looks bent at the point where it touches the water, because light coming from the submerged portion of the pencil gets refracted as it crosses the water-air boundary.

Watching TV in Dark

In this satellite century, more and more people are watching television for entertainment and subjective knowledge. But many people have doubts regarding the distance that should be maintained from television while watching, mode of watching and the effects of watching television in darkness, etc. Many people believe that the picture on the television can be seen much clearly in darkness. So they close down all the doors, windows, put off the lights and then watch the television. It may be true also. But by watching television in darkness, eyes get tired quickly. Visionary faults may occur. Actually one can watch the television in dim light also. Eyes would not get tired quickly by watching television with more illumination of light in that room. Also no visionary defects occur. It is good for health to watch television at a distance of two and half meters or seven feet from the television. When we sit for watching television, care should be taken such that the angle between the centre point of television screen and our eyes should be around 10 to 15 degrees so that neck muscles would not undergo unnecessary stress. That’s why it is better to follow guide lines while watching television. Extreme care should be taken in the case of children.

Blurred Vision

The images appear zig zag after the eyes are rubbed. If the eyes are rubbed normally this situation do not takes place. But if the eyes are rubbed with full force, the pressure is fallen on the muscles of the eyes, pupil, and connective tissue and on the eye lenses. This is called as the mechanical stress. This means, the balanced structure which is seen inside the parts of the eye will be damaged temporarily. At that stage, the light rays which passed in to the eyes, do not travel in their normal position. The eye ball does not concentrate totally on the image which is seen in the retina. For some time, the coherence on the vision will become imbalanced. So, the images appear as unclear and blurred. After some time, this problem will be solved. On the whole, it is not good to rub the eyes often which damage the vision of the eyes.

Tears

Reason for tears when we cut onions


There is correct reason for getting tears in the eyes while chopping the onions. There is a substance in onion which brings tears in the eyes and this is called as propenesulfenic. When we cut the onion, this substance mixes in the air and hits our eyes. And then eyes get irritated and we get tears. Science tells that the tears from the eyes are good because the dust in the eyes gets washed away.

Hiccups

Why do we hic-hic-hiccup? What causes them?

When you hiccup, your diaphragm and nearby muscles convulse, causing you to briefly gulp air. Within 35 milliseconds, the glottis (the opening at the top of the air passage) slams shut, producing that familiar sound of the "hic."

Hiccups are usually a reaction to your stomach and digestive system getting wonky. This happens when you eat too much, drink bubbly drinks like soda, or swallow too much air. Some people get the hiccups for no reason at all. Other things that cause hiccups include skull fracture, epilepsy, tuberculosis and believe it or not, constipation (not being able to poop).

Unlike sneezing, farting, burping, etc., hiccups don't serve any purpose. They're just annoying and pointless! So how do you get rid of hiccups? Which remedy works best? Home remedies are usually based on the idea that you have to disrupt the hiccup cycle. Remedies include holding your breath, breathing into a bag, pulling your tongue, sudden fright, or eating sugar. Just drinking water, if done soon enough, might wash down a chunk of food in the throat that's pressing against a nerve.
