Ants are social insects. They live in big colonies and have a very organised social life. Red ants make their nests inside the walls of our houses. They generally travel large distances in search for food. In absence of any maps or navigation aids, they have to rely on other mechanisms to find their way around.
Scenting their way
As they walk the ants leave behind a scent that they use to trace their way back to their nests just as in the fairy tale Hansel and Gretel, the children left a trail of pebbles to find their way home from the jungle. The scent that the ants leave behind is called pheromone. The ants walk in a line because they follow the scent left behind by the leader.
There is an ongoing debate about why dolphins jump out of the water. Scientists think about different reasons of this behavior. Among them, some think that dolphins jump while travelling to save energy as going through the air consume less energy than going through the water. Some other think that jumping is to get a better view of distant things, mainly food. So, in this way, dolphins jump to locate food or food related activity like seagulls eating or pelicans hunting.
Other explanation suggest that dolphins use jumping to communicate either with a mate or with another pod. Some people even think that dolphins jump for cleaning, trying to get rid of parasites while jumping. Finally some scientist think that they are only having good fun, as playing helps to keep senses at their best.
That's a good question. Laptops get hot because they are computers and all computers get hot. In fact, humongous main frame computers require a special air conditioning system just for the computers. I guess the question now is why do computers get hot? Computers get hot because they are composed of electronic components that all generate heat as a by product of using electricity. The main producer of heat is the CPU (Central Processing Unit or main Computer Chip). That's why you will always find at least 1 fan on a modern laptop and that's for the CPU. Typically you will find 2 fans on a desktop. One for the CPU and one for the power supply. The ingenious thing about
Have you ever wondered why shaking a soda results in a great explosion when it's opened? What causes a 2-liter bottle of soda to go flat? Is there anything that can be done to keep fizz in a bottle of soda? Get ready to uncover some amazing soda secrets that will change your soda drinking habits.
Since the fizz in the soda is actually dissolved carbon dioxide gas, the goal is to keep as much of the gas in the bottle as possible. Soda fizzes when dissolved carbon dioxide gas is released in the form of bubbles. At the bottling plant, carbon dioxide molecules are forced into the soda in an amount that is greater than would ordinarily dissolve under atmospheric conditions. As soon as you open the bottle, most of the excess gas escapes into the room – that's a given! So, it's your job to find a way to keep the remaining gas in the liquid.
What the pigeon is actually doing as it moves its head back is keeping its eyes absolutely still compared to the world around it.
This is thought to make the job of processing visual information easier for the pigeon. If you walk along normally things move due to parallax, things close to you appear to move across things further away.
This is a nightmare of a task to decode (a task that machine vision scientists are still struggling with) and takes a hefty amount of processing power. Brains use a lot of energy so avoiding difficult processing reduces the amount of food you need to find to survive, so it appears the pigeon has used a clever mechanical trick to avoid the computation.
