Yes Scientists believe the existence of a super natural power which is responsible for all that is happening in this world. Many of them are trying to understand what is that power and how it works. Scientists are also human beings like us , they also will have their beliefs. The Chairman of ISRO, whenever he comes to Sriharikota for launching of a Satellite, makes it a point to visit Chengalamma temple in sullurpeta oneday before in the evening. It is the belief of scientists that the launching will be successful. But the point we have to observe here is the scientists will work day and night to make the launching successful. Any small doubt also they will not leave unattended. The drill they do every time is meticulous and no loose tags they will leave. 24 hours before they start countdown and every minute and every second there is a point to be observed and confirmed. After doing all this they go and pray God for success. This will give them additional energy and enthusiasm to work. Without doing anything, believing the existence of God and leaving everything to him may not be liked by even GOD also.
