Why do Clocks Run Clockwise?

Why do Clocks Run Clockwise?

“Time to get dressed!” cries a harried Mama as she tries to pack the bag, straighten the tie, pack lunch, tie shoelaces as at the same time she pushes children dragging their heels towards the bus stop. Oh? Is it already “Time for school?” later still its “time for dinner” or “time for bed!” Old Father Time can be quite an interfering busybody and there really is nothing we can do. Most of us spend a greater part of our time and lives trying to beat exactly this – time!...

Why don't Birds on a wire get a shock?

Why don't Birds on a wire get a shock?

Now how is that possible? The fact is, for a living creature to get a ‘shock’ there has to be a substantial flow of current through the body. However, there is barely any current running through the bird’s body for two reasons. Firstly, the bird not only forms a circuit with the wire, but it also offers a high resistance to current, so the current passes through the wire instead of the bird. It’s a bit like this, would you prefer going on a smooth road or a road full of potholes?...

Why does the Sun follow You?

Why does the Sun follow You?

Have you ever noticed that when you are in a car, or a bus, travelling on a straight road, the Sun appears to move right along with you? While telephone poles and trees close to the road, whiz past in the blink of an eye, the Sun is always visible throughout the journey. No matter how fast Daddy drives, you just cannot leave the Sun behind. Strangely enough, the trees nearer the road disappear from your range of vision more quickly than the trees further off....

Why doesn't our stomach get digested?

Why doesn't our stomach get digested?

All the food we eat goes into our stomach. Here, it is broken into smaller and simpler substances and get absorbed into the blood.

Why is the Dead Sea dead?

Why is the Dead Sea dead?

The Dead Sea is indeed a very scary name for a lake. It is called so because nothing lives in it. There are no sea weeds or plants, no fish either. This is because the Dead Sea is nearly six times as salty as the ocean. It also contains many other dissolved minerals, including magnesium chloride, calcium chloride and potassium chloride in large quantities. Whereas in fresh water, only minute quantities of these minerals are found....

Why's it hard for Ketchup to flow?

Why is it so tough to get ketchup out of the bottle? Why’s it hard for Ketchup to flow? [Illustration by Shinod AP] When you overturn a sauce bottle that has been left untouched for some time, chances are, either the sauce will not come out at all or a gigantic blob will plop down on your plate.

Why do Locusts Swarm?

Why do Locusts Swarm?

Have you ever tried chasing a frisky grasshopper? If you have, you will definitely know that scampering after a jumpy bug is not an easy task. Most species of grasshoppers have a keen sense of hearing and the moment they sense trouble, they can hop fast and furious! Sometimes, shortage of food turns grasshoppers into migratory insects as they venture out in search of newer pastures. This situation happens when the species begins reproducing rapidly and does not have enough food for all the members of its community....

Why do we Blink?

How many times do you blink in a minute? Weird, who knows! Well, mostly people blink around 15 times a minute (Reader’s Digest – Why in the World). Blinking is an involuntary action that protects the eye. Most of our eye is enclosed in a bony socket covered with a layer of fat, which forms a protective cover. But when the eyes are open, one-tenth of the total surface area is exposed to the atmosphere. This means the eye, the most delicate and sensitive part of the body, has to withstand the dust present in the air....

Why do Cats Always Land on Their Feet?

Why do Cats Always Land on Their Feet?

When someone falls from the fourth or fifth floor, and survives, we call it a miracle. When a cat falls from that height, we watch astonished as it lands on all fours, pauses, then straighten up and walks away looking just a little fazed. What would you call this, a miracle or God’s grace? Any guesses why cats survive while humans don’t? Well, it all has to do with the in-built ability of a cat to adjust its position during a sudden fall, its light weight and lithe muscular body....
