Do stars come in different colours?

[Stargazing is one of my favourite things to do but I only get to do it overseas! The stars look like a veil of twinkling diamonds covering the regal sky. Instead of sleeping early, I would stay up and stare at them while dreaming awake. Even though Singapore has many lights at night which makes it hard to see the stars, there are still a few good places for stargazing such as the Singapore Science Centre's Observatory [1] or Pulau Ubin. What stargazing spots have you been to in Singapore?]

Yes, many stars shine in different colours and the colours vary depending on the outer layer of the star’s temperature.  The hottest stars are usually blue-white.

According to ‘Explore: One encyclopedia, a world of knowledge’:  ”All stars look white to us because their distance makes them dim. Stars a little cooler than the Sun are yellow and even cooler ones are orange or red. Some stars also look red because their light shines through dust clouds.”

Is it true that there were children raised by animals?

[My favourite wolf-boy will always be Rudyard Kipling's Mowgli of The Jungle Book, together with the Disney movie remake which I watched countless of times as a child: "Look for the bare necessities/ The simple bare necessities/ Forget about your worries and your strife..."]

There have been reports about children being raised by animals, more commonly by bears and wolves.  According to ‘The Rough Guides to Unexplained Phenomena’, most accounts of wolf-children recorded since the early nineteenth century have come from India, mostly from the jungles of Bengal. One example would be the documented history of the Midnapore children written by The Revd J. Singh (Wolf Children and Feral Man, 1942), who had discovered and later on brought up the children. Singh was a missionary of the Minnapore Orphanage who made regular evangelical trips to the aboriginal tribes of his district. In 1920, people from a village reported to Singh about two small ‘ghosts’ with big eyes always walking with the wolves back to the den. After investigating, those ‘ghosts’ were actually 2 little human girls aged 1 & 1/2, and 8 years old respectively. Singh took them back with him to the orphanage. Unfortunately the younger one died within a year and she never spoke or walked upright however the other girl learnt to stand, eat human food and speak a few words under his care.

 Other accounts include the two Syrian gazelle boys reported in The Sunday Times, August 1973 and in London’s Daily Mirror, February 1971. One of them could run at 50mph with the gazelles and had superb eyesight and very sharp hearing. The other one would approach gazelles and lick their foreheads as though saying hello and showing that he recognizes them.

There is also the ostrich boy, Sidi Mohamed, who told his story, and is quoted by Armen from Notes Africaines (April 1945), about how he came upon an ostrich nest in North Africa at 5 or 6 years old and stayed there. The parent birds returned to the nest and they became used to him. For ten years, he stayed with them and survived by eating grass and learning how to match their speed in running. At night, the two ostriches would extend a wing over him as shelter. Sidi was found by hunters one day and returned to his parents. It took him a long time to readjust to human ways and he was always wishing for his old way of life among the ostriches.

What Is The Difference Between Turtles And Tortoises?

Which is which? Can you tell the difference?

Turtles, tortoises, and terrapins all belong to a division of reptiles, called chelonians.

In general, turtles live in or near the water and have adapted to swim by holding their breath underwater. Tortoises live primarily in arid regions, built for storing their own water supply and walking on sandy ground.

Biologically, a tortoise is a kind of a turtle, but not all turtles are tortoises.

Turtles have flatter backs than tortoises, and may spend all or part of their lives underwater. They mate and lay eggs underwater or on the shore. During cold weather, they burrow in mud and go into torpor, a state similar to hibernation. Sea turtles migrate great distances. They are more often omnivorous, eating plants, insects, and fish.

Tortoises, however, live entirely above water, only wading into streams to clean themselves or to drink. In fact, they could drown in deep or swift current. Tortoises, unlike turtles, are mostly herbivorous, eating cactus, shrubs, and other plants that have a lot of moisture. They rarely migrate. Their shell forms a rounded dome, allowing the tortoise’s limbs and head to withdraw for protection.

What Is Candy Made Of?

candy.JPG
Image taken from: http://epicute.com

February is a month of clelebrations with sweets and all things nice. But after feasting on candy on New Year’s and Valentine’s, have you ever wondered what goes into the yummy delicious candy?

Well, candy is made of supersaturated sugar or sucrose.

When you cook up a batch of candy, you cook sugar, water, and various other ingredients, (depending on the flavour of the candy) to extremely high temperatures. At these high temperatures, the sugar remains in solution, even though much of the water has boiled away. But when the candy has been cooked and begins to cool, there is more sugar in solution than is normally possible. The solution is said to be supersaturated with sugar.

Supersaturation is an unstable state. The sugar molecules will begin to crystallize to solid . Stirring or jostling of any kind can cause the sugar to begin crystallizing.

The fact that sugar solidifies into crystals is extremely important in candy making. There are basically two categories of candies – crystalline candies (candies which contain crystals in their finished form, such as fudge and fondant and noncrystalline candies (candies which do not contain crystals, such as lollipops, taffy, and caramels).

The ingredients and procedures for noncrystalline candies are specifically designed to prevent the formation of sugar crystals, because they give the resulting candy a grainy texture.

Here are more books about candy that you can check out!

What is bioluminescence?

[I watched a scene on 'Animal Planet' a few years back that I can recall very clearly today because it was scary yet magnificent- the way the female black dragonfish tempted the shrimps with its brightly lit, long bristle hanging from its chin. The shrimps were attracted to the glow and swam closer, only to end up too close and...YUM! They became dragonfish's dinner. I guess it mirrors life too, always practice caution no matter how pretty things are looking on the outside. Have you seen bioluminescence at work?]

Bioluminescence is the ability in some animals to create their own light, through chemical reactions in their bodies.

According to The Usborne Book of Knowledge:  ”Animals use it to communicate with each other, to find mates, to catch prey or to defend themselves. For example, glow-worms light up their bodies to attract a mate. Many deep sea fishes produce light for defence. Comb jellyfish release clouds of brightly-glowing particles when they are being attacked by a predator. The particles temporarily blind the attacker, providing a chance for escape.”

How much do you know about S.Rajaratnam?

raja.jpg 

 

On 4 February 2010, MP Irene Ng along with guest-of-honour, Prime Minister Lee Hsien Loong, launched the first of her 2-part biography on former minister, S. Rajaratnam. The first part, which is devoted to the memory of S. Rajaratnam and his enduring vision, is titled ‘The Singapore Lion’.

 

Sinnathamby Rajaratnam (25 February 1915 – 22 February 2006), better known as S. Rajaratnam, was Singapore’s first foreign minister. He held the post for 15 years from 1965-1980, and held the post of deputy Prime Minister from 1980-1985.

 

In 2007, the Institute of Defence and Strategic Studies at Nanyang Technological University (NTU) was renamed as S.Rajaratnam School of International Studies (RSIS) to honour his contributions for Singapore.

 

Currently, there is an exhibition on S. Rajaratnam at the National Library Building on level 10. It will run from 4 February to 4 May 2010.

 

Has Mr Rajaratnam written any books?

He has published a number of books. You can find the locations and availabilities of the books by following the links below:

1) S.Rajaratnam on Singapore: From Ideas To Reality

2) S. Rajaratnam: The Prophetic and The Political

3) Preserving Non-alignment

 

 There are more books by S. Rajaratnam. Go to searchplus.pl.sg and type in S.Rajaratnam for more results.

 

Where can I find out more about S.Rajaratnam?

1) S. Rajaratnam

2) The voice of a nation: S. Rajaratnam

3) Raja: From Minister To Citizen 

4) The Singapore Lion

 

One little trivia about Mr Rajaratnam: Did you know that he penned our national pledge in 1966 after Singapore gains her independence on 9 August 1965?
