He studied a type of material called " spin glass" , in which, for example, iron atoms are mixed at random into a matrix of copper atoms.

他研究了一种名为“自旋玻璃”的材料，例如，在这种材料中，铁原子被随机混合到铜原子内部。

The iron atoms each behave as tiny magnets but, whereas in a normal lump of magnetised metal their north-south poles all point in the same direction, in a spin glass they do not.

每个铁原子的行为都像微小的磁铁，但在正常的磁化金属块中，它们的南北极都指向相同的方向，而在自旋玻璃中却不是这样。

When Dorothy followed the Sorceress into this delightful patio all the fifty girls were busily weaving, and their shuttles were filled with a sparkling green spun glass such as the little girl had never seen before.

当多萝西跟着女术士走进这个令人愉快的庭院时， 五十个女孩都在忙着编织，她们的梭子里装满了闪闪发光的绿色纺纱玻璃， 这是小女孩以前从未见过的。

Dr Hopfield was responsible for what has become known as the Hopfield network—a type of artificial neural network that behaves like a physical structure called a spin glass, which gave the academy a tenuous reason to call the field " physics" .

霍普菲尔德博士负责的研究项目后来被称为霍普菲尔德网络， 这是一种人工神经网络， 其行为类似于一种名为自旋玻璃的物理结构，这让科学院有理由将该领域称为“物理学” 。
