Special Types of Bipolar Fuzzy Graphs,the planet’s surface from those harmful rays. It is decomposed by other compounds, but particularly by some man-made gases, such as chlorofluorocarbons. An international agreement, the Montreal Protocol, is succeeding in phasing out the production of most anthropogenic agents destroying ozone.

Putting Numbers on Geologic Ages,g fossil fuels would warm the planet. It was soon realized that the rates of decay of radioactive elements could be used to date rocks. The Earth’s age turned out to be measured in billions, not millions, of years. By 1920, a numerical age framework similar to the one we have today had been established.

Exploring The Electromagnetic Spectrum,adiation by generating it in his laboratory. He did not realize the implications of his discovery. Giuseppe Marconi made the electromagnetic spectrum a tool for civilization, developing radio transmission. Human use of the electromagnetic spectrum has expanded to include FM radio, television, radar, and even microwave cooking.
