Now Wheelchair Can Send Signals!!

Hello friends, I am back after enjoying a great week end. This time I have come up with a post which is about an awesome wheelchair that obeys signals from human beings sent to a computer. The Italian scientists have invented this wheelchair which reads the signals from the user. The person who is sitting on the wheel chair is connected to a computer with some electrodes on their scalp.

The computer reads the signal which the user sends to the computer through the electrodes. Isn’t that interesting? Let me explain you about how this works. A screen will be displaying the destination like bedroom, kitchen, bathroom, etc. The user just concentrates on the destination where he has to go for a few seconds. Using this, a signal will be sent to the computer and the computer just guides the wheel chair to the desired room with the help of a preset program written in it. The computer reads the signal from the brain that is sent and not the minds of the user. The obstacles can be detected using the two laser beams in the wheelchair.

Finger Length Tells About You!!

Finger-length ratios have always been compared to the characters of the people. Some people even predict the fertility and disease vulnerability according to the finger-length. But now, it has been said that boys run faster if they have ring fingers longer than their index fingers. The researchers have found that kids who run faster have exposure to testosterone in the womb and this also remains the reason for their finger-length ratios.

In a talent spotting competition, 241 boys aged 10 to 17 were studied by the researchers to research about the finger-length comparisons. It was observed that boys who had longer ring fingers were faster in a 50-meter race and this was observed at every stage of the race. As soon as they started the race, their advantage was apparent and it also remained the same throughout the race. In a research which was done previously, it has been said that the aggression in men can be predicted with the help of their finger length. But this might not be true in the case of women. Kids who have longer ring fingers are predicted to have math scores higher than the scores in literacy or verbal.
