Nickel, Nature and the Environment

Nickel has been peeled off from its naming (stainless steel) and become a kind of element, an object, which means nickel is much more than a restored metal. No matter how close it is to us, in the coach of the high-speed rail, or at the two sides of the pedestrian overpass, we can see and touch it. Or how far it is away from us, coming from the Cambrian period of 400 million years ago. However, we are still not 100% confident to say that we have understood it and its environment. Nickel has still been waiting for us to explore outside of the environment we are familiar with. Being an object, Nickel and nature have always been in the process of being understood.——— WangJianwei
