Why do Onions Make us Cry?
One of the earliest memories I have as a child is when I was approximately three or four years old. I remember watching my mother work in the kitchen. She was cutting onions for the salad and I could see tears in her eyes. For a child the worst possible thing is to watch his/her mother cry. I got so upset that I got hysterical at my father for causing her pain. For I assumed my father was somehow responsible as we were only the three of us in our family....
Why is Snow White?
I am sure like my two kids, all of seven and three years, you too may find the cold in Delhi a bit too extreme. It is cold and clammy and some days it is foggy making it dangerous to drive. Some days I would like them to be adequately muffled up in warm winter clothing, while they feel quite comfortable running around in a sweater and shorts! But most days it was grumble, grumble, grumble!...
How did the Pineapple get its Name?
What prompted people to call banana a banana and a pineapple a pineapple and not something else? Actually there is a reason behind the names given to each and every thing; be it a fruit, vegetable, an animal or inanimate objects like stars, planets, etc. However, sometimes the names are misleading, Take the example of pineapple: no it doesn’t come from a pine tree, nor is it an apple. When you look at a pineapple you may think you are looking at one fruit....
What is a Kangaroo Rat?
It looks like a small kangaroo for its hind legs are longer than its fore legs. And it uses its tail to balance itself. In fact, unlike other rats it does not run on all four legs but jumps around from bush to bush in search of food – like a kangaroo. And that’s why it is called the kangaroo rat. It has another unique feature. Unlike most animals, the kangaroo rat does not need to drink water....
What is Leukaemia?
Some 15 years back when I was still in school, our class teacher, Mrs. Khurana, would remain absent from school and class almost every other day. We kids were very happy without realising and neither did we bother to find out the reason for her absence. It was only later that our principal informed us that Mrs. Khurana’s only son was suffering from leukaemia (wrongly called blood cancer). I remember later that Mrs. Khurana took her son to abroad where he underwent a bone marrow transplant....
Who or What is a Gladiator?
It all started in ancient Rome. The most brutal sport that has ever existed in the history of the world was the fights between gladiators. The ‘sport’ traces its roots to the custom among the Etruscan people, a civilisation in Italy that existed before the Roman civilisation. At the death of the master of the house, servants would duel to the death for the right to follow their owners in death and provide help and company....
How Will our Sun Die?
Everything that is born must die. Not only living beings, but inanimate objects like stars too. The birth of a star The universe has massive clouds of hydrogen floating around. Sometimes, these clouds come together and form very dense and huge balls of hydrogen gas. As the clouds come close, their temperature increases. This is called a proto-star (original star). The increase in temperature triggers off nuclear reactions at the core of the star. Nuclear reactions inside the star occur when the nucleus of two hydrogen atoms fuse to produce a helium atom....
Can Two People have Identical Fingerprints?
I was once watching a detective serial on T.V. where the fingerprints of the suspect are required. The hero invites the villain to his home and offers him a glass of water. The bad guy takes the glass and drinks the water from it. After he leaves the hero dramatically whips out a handkerchief and picks up the glass. His expressions showed that satisfaction at a job well done. At that time, I found it amazing – how can smudges on a glass identify people?...
Is Potato a Fruit or Vegetable?
Pick up a potato and you notice eyes with little lashes on it. In fact, the lashes look like tiny roots. Have you ever wondered why the potato has roots on it? The potato is actually a stem. A stem in disguise, that grows under the ground! Many plants are masters at adapting themselves to their surroundings. They can change their structure to suit their needs. Farmer holding harvested dirty potatoes in his hands....
Which is the Most Abundant Fruit in India?
Did you know that in India, mango orchards cover roughly 33 percent (1.08 million hectares) of the total area under fruit cultivation? In a hectare of land you can grow thousands of trees. And each tree bears, thousands of fruit! I will leave it to you to calculate how many mangoes the country produces! It’s no wonder that the subzi mandis (vegetable and fruit markets) get flooded with mangoes in summers. Forget the fact that the country produces millions of mangoes, do you know how many varieties there are?...
