What causes a scientist to reject an idea and replace it with a new one?

Have you ever had that feeling in your stomach that something is not right for you, or some person is not right for you. I have changed my position, religion, beliefs many times and each time I have grown and improved. Life isn't about standing still in the same place, it is questioning, listening, wondering, searching etc. I do not want to pass over to whatever is there, the same as I was when I was 20,

I am 76 years of age, and I have a life that has been full of joy, excitement, possibilities and I have also had really bad experiences i.e. a battered wife. However, everything has led me to where I am now, which is a wonderful place to be.

Everything I ever went through, negative and positive, has led me in the right direction BECAUSE I chose to change.

Why is it important for scientists to communicate with their observations theories and investigations?

1. You should do your own work and answer things for yourself. But I'll answer anyway.

One person might have a completely new and bright idea about how to go about something that changes the entire field of study. Even if this method isn't new and exciting and the scientist may have made many mistakes, people while learn by example and avoid making the same ones.

Which scientist made the first accurate measurement of the earth?

Ancient writing indicates that Pythagoras postulated that the earth was round, and, about a hundred years later, Aristotle argued the same thing. Even before this, ancient peoples could see the round shadow of the earth on the moon during an eclipse. The thinking person could figure out why this would be so. It doesn't take a rocket scientist, and, though ancient peoples didn't have rockets or even aircraft to get a "bird's eye view" of things, they could observe and make conclusions quite well. Beyond these early ideations, both Pythagoras and Aristotle offered a "guestimate" of the earth's size, so it could be one of them. But it was Eratosthenes who got into it and make a nicely accurate calculation of the earth's circumference. It is possible that some other ancient investigators put forward some projections, but the written record, which suggests most clearly the who, what, when, where, and why of things olde, does not give us any other candidates.
