 True Facts about Light

Hey you all, I am so glad to see you here. Well then, let's go back to the post. Here, you will find that I was really inspired by "light" lately. Sounds ridiculous, I know. But I had a dream last night. I dreamed that I was studying light in a Physics class ( which I used to take when I was in college). But then my Professor asked me a question about light, and how does it react to objects... I went totally blank. Thanks to all this. it was just a dream. 
But this just made me think- why not make a post on my blog?? So here you go.... my dream...:)




 What is Light?  
Light is a form of energy, called Electromagnetic Radiation. Light travels very fast (around 300,000 km/s) and goes straight. Light rays travel only straight lines, but they can be bend by a proper material.

How does Light bend?
The bending of light is called Refraction. Refraction occurs when light travels from one medium to another, e.g from air to water. When light enters another medium, its speed changes due to difference in density.

Why does light have so many different colours?
There are different colours of light because they are light waves which have different wavelengths. Red light has the longest wavelength while violet light has the shortest wavelength



What are the Primary colours?
Red, green and blue would be the  primary colours of light. Mixing and experimenting with those colours will create a range of many other colours, including white.

What makes a rainbow?
When sunlight is intercepted by a drop of water in the atmosphere, some of the light refracts into the drop, reflects from the drop's inner surface, and then refracts out of the drop. The first refraction separates the sunlight into its component colours, and the second refraction increases the separation. The result is a rainbow.




How to control Light?
Light can be controlled by 3 ways: Blocking, Bending and Reflecting.
Blocking- blocking a light will create a shadow
Reflecting - reflecting light with a mirror to change its way.
Bending- also called refraction- going from one medium to another.

 Cannibalism

Hey guys, so I wanted to make a totally different post today, something we may already know, but not too much about it. I want to write about Cannibalism, what is it exactly and is it still present. So enjoy!!

 
Cannibalism  is the act or practice of humans eating the flesh of other human beings. A person who practices cannibalism is called a cannibal.
 Cannibalism may also refer to the act of any animal consuming another animal from the same kind or type.


 But have we ever thought of what might have led to cannibalism? What made humans act like this?
Here is a short list of the reasons:

  •  Cannibalism is known as a cultural norm - cannibalism cultures believed that by eating for example, a brain from a member of their village will give them strength and power.
  • Famine - starvation also led to cannibalism- the survival during harsh times made cannibalism a daily ritual. 
  • Cannibalism was also caused by insanity or social deviancy.









 Cannibalism has recently been both practiced and fiercely condemned in several wars, especially in Liberia and Congo. Today, The Korowai have been reported to practice ritual cannibalism up to the present day. Anthropologists suspect that cannibalism is no longer practiced by the Korowai clans that have had frequent contact with outsiders. Recent reports suggest that certain clans have been coaxed into encouraging tourism by perpetuating the myth that it is still an active practice.



  In 2006, the television show 60 Minutes claimed that when someone in Korowai society is convicted of being a khakhua (secret witch doctor) he or she is tried, and if convicted he or she is tortured, executed, and eaten. Other unverified claims were made that the brain is usually eaten immediately, while still warm, and that pregnant women and children don't participate in the cannibal act.


 There are fundamentally two kinds of cannibalistic social behavior;endocannibalism (eating humans from the same community) and exocannibalism (eating humans from other communities).
A separate ethical distinction can be made to delineate between the practice of killing human for food (homicidal cannibalism) versus eating the flesh of a person who was already dead (necro-cannibalism).

Something about the Stars....



We may all have a slice of knowledge of what stars are, but do we actually know a lot about them?
I have been reading a science magazine in my dentist's waiting room lately  ( not that I am a big fan of science, but when I have a chance, I read about what's going on up there in the sky). While running through the magazine I discovered few facts about stars. Here is a bunch of facts about them....






Stars are huge balls of gas in outer space. They are made from helium, hydrogen and other elements, they produce heat, light and other forms of energy. The twinkling stars that you observe in the night sky are actually very far away from the earth. Our Sun is also a star, but it is much closer to our planet, Earth, therefore it looks much bigger.




The Sun has planets and other objects moving around it. The Solar System is made of our Sun, Earth, other surrounding planets and rocky objects all together. Many stars have planets moving around them too.

It is believed by astronomers that there might be approximately  70,000,000,000,000,000,000,000 or 70 sextillion stars in the Universe. But when you look at the sky, you may see 3,000 with your naked eye. 

The poetry “twinkle twinkle little star” must have been inspired by those beautiful stars twinkling in the night sky. But have you ever wondered why stars twinkle at night? The twinkling of stars is actually caused by the movement of Earth’s atmosphere. The light emitted by the star enters the atmosphere in a straight path, but we see stars twinkling because air movements in our atmosphere change the paths constantly, hence the twinkling.


Stars come in different sizes. Some are smaller than our Sun whereas others are so huge that our sun is a mere dot when compared with their size. Some stars, called supergiants have a radius of about a thousand times that of our sun. The smallest stars are called neutron stars.

''Frozen People brought back to Life'' study shows

 
How is it possible for a human, who had just froze to death, come back to life??
After years of examining and experimenting on living matters, the scientists are finally reaching the end of this chain of questions.

It has been proven that yeast and worms can survive hypothermia if they are first subjected to extreme oxygen deprivation. This bring a small conclusion that humans may survive too, after removing the oxygen.


Scientists have been experimenting on worms and yeast, though. When subjected to literally freezing temperatures, the embryos of yeast and garden worms do not live, researchers found. A full 99 percent of those in the experiment died after 24 hours of exposure to temperatures just above freezing.


But, when first deprived of oxygen in the manner described above, 66 percent of the yeast and 97 percent of the garden worms survived. Upon re-warming and reintroduction of oxygen, the "two widely divergent organisms" reanimated and showed normal life spans, said scientists in a statement.

This proof widely opens a gate of mysteries.  It can solve many reported instances of humans "brought back to life" after succumbing to hypothermia. Instances, such as no heartbeat (mostly known as being clinically dead) and low body temperature.

 ''Forced Hibernation'' is the right term given to this procedure. A human being may be put to death by first removing oxygen and then locating the body to a decreasing temperature area.



Human Experience with ''Forced Hibernation'':

 
Erica Norby

During winter time, the Canadian toddler, with the body temperature of 61 degrees Fahrenheit (16 degrees Celsius) laid for hours in below-freezing weather after wandering outside wearing only a diaper. Apparently dead, she recovered completely after being re-warmed and resuscitated.


 


 
Mitsutaka Uchikoshi

a Japanese mountain climber, who was discovered with a core body temperature of 71 degrees F (22 degrees C) after 23 days after falling asleep on a snowy mountain.

Mauritius - Heaven on Earth


Officially the Republic of Mauritius, an Island located on Indian Ocean and off the southeast coast of Africa. The main languages spoken there are Mauritian Creole, French and English. Only recently has the Island become independent (since 1968). Before this year, it has been ruled first by the Dutch, then the French and lastly by the British during the Napoleonic Wars.





The climate in Mauritius is typically tropical with the addition of southeast trade winds; there is a warm, dry winter from May to November and a hot, wet, and humid summer from November to May. The warmest months are December and January where temperature rises up to 36'C and the coldest months are September and August with a temperature of 16'C.
  Cyclone affect the Island during November until end of April. The two worst and last cyclones that affected Mauritius were Hollanda in 1994 and Dina in 2002



The Island itself is just Beautiful. Fantastic weather, amazing view and an incredible adventure. The island itself is a quiete and peaceful place, meaning that there is low crime and is very open to tourists and there is plenty of attractions for each visitor. From swimming in the warm Indian ocean to mountain climbing.


Their culture is  influenced by the Indian, Creole, Chinese and European culture. It is common for a combination of cuisines to form part of the same meal. You have the Chinese Spring festival- The festival is the Chinese New Year,  and is celebrated in January/February, depending on the adjustment of lunar days. And you have many other festivals including Hindu and Muslim festivals.
