Earth clock, the common heritage of mankind

The earth clock is a far-reaching art project, which was initiated by Swiss artist Max Beer in 1982. This huge earth clock was built in front of the main building of Swiss Federal Institute of Technology (ETH Zurich). This is a sculpture made of metal and glass.

The main body of the earth clock is a 3.5-meter-diameter iron plate with a global map printed on it, which accurately shows the time difference around the world. The hands of the clock on the disk turn once every 24 hours, which means that there is only one place on the whole earth where the time is constant: Greenwich Observatory in Britain, which is the location of the zero meridian. When London time is noon 12, the time in other parts of the world can be accurately calculated by the time difference pointer on the earth clock.

In addition to the hour hand, the earth clock is equipped with other instruments, such as barometer, thermometer and hygrometer, to reflect the weather. The data measured by these instruments are also used in scientific research.

The construction of the earth clock has gone through a long and tortuous process. From 65438 to the early 1980s, Max Villa, together with some scientists and engineers, started this arduous project. It took them several years to research, design and build, which cost 654.38+500,000 Swiss francs. The earth clock was finally completed in 1986, becoming a unique artistic and scientific tool.

The significance of the earth clock is that it is not only a work of art, but also a human heritage. It shows the connection between human beings in time and space, and their concern and cherish for the natural environment of the earth. As a work of art, science and technology, the earth clock not only symbolizes human creativity and wisdom, but also inspires people to love and protect our planet more.

Today, the earth clock has become a famous landmark in Switzerland, attracting tourists and scientists from all over the world to watch and study. Its existence reminds us that the planet we live in is a precious and fragile resource, which needs our Qi Xin to work together to protect and cherish.
