Could plants feel happiness, sadness and angry?

A Indian botanist whose name is Bose has carried out an experiment: he waved a rake before a plant. As a result, the tentacles of the plant wave together with the rake, as if the plant is forbidding any harm from rake by waving its tentacles. Based on the experiment, Bose made an assumption that a plant has a heart. Besides, Bose invent a Cardiac curvometer and found out that the plants not only have hearts, but also have impulse. And the activity circle of the hearts is 1 minutes.

Assumed that the plants have hearts, they would have emotions.

In 1996, a scientist called Baxter has connected the Lie detector’s electrode to one of the leaves of dragon tree. He watered the dragon tree first and a smooth sawtooth-like curve has appeared on the detector. It seems that the dragon tree was feeling comfortable.

Then, he dipped one of the leaves into hot coffee, the reaction on the detector sent out a response of slight fear, which is not too terrible.

However, when he decided to burn this leave and held burning match near the dragon tree,the needle on the detector showed a strong wave. And apparently, this is the reaction of fear. When Baxter take back the match,the detector showed that the dragon tree has resumed normal state.

Now you may understand that trees have emotions like people. So we must take care of them!

Friction happens when things rub against one another.

Rub your hands together. Does it feel warm? This is because of friction.

Your hand may look smooth to you, but zoom in very very close, you will see that it is actually rough. The rough edges of one hand catch the rough edges of another, but each hand tries to ‘get away’ and continue to slide. This is friction.

Friction is a good thing to have though. Cars stop moving because of friction between the brake and the tyre.

Let’s try something out. Take your toy car. Give it a push and see how far it goes on a smooth floor. Try the same on a carpet, and on your driveway. Where does the car move the most?
