In the present article, we show one part of the processes and changes that occurred in our environment during the last 165 years. Performing of our work was difficult because some of the data required are missing and those which were published in single papers frequently differed from each other. It is also a problem that we are neither mathematicians nor physicists. Despite these difficulties, we hope that our efforts will not be fruitless.展开更多
