The age of the earth has been a topic of debate among Christians over the last two centuries.Several Christian ministries promote the idea that the earth is less than 10,000 years old, which they say comes from the Bible.This site, closely coupled to The Natures of the Stars and The Hertzsprung- Russell (HR) Diagram, provides an introduction to the spectra of stars and allied celestial objects.
In frustration, they had named it ‘kupfernickel’ which could be translated as ‘goblin’s copper’ because clearly, from the miners’ point of view at any rate, there were goblins or little imps at work, preventing them extracting the copper.
It was not until the 1750s that nickel was discovered to be an element.
In the 1600s, a dark red ore, often with a green coating, had been a source of irritation for copper miners in Saxony, Germany.
Miners in Germany believed little fellows like this one had stopped them extracting copper and silver from nickel and cobalt arsenides.
Fortunately George Brandt and Axel Cronstedt took a more scientific approach to the problem and discovered two new elements. Nickel is present in metallic meteorites and so has been in use since ancient times.
