1925年,科学家泡利发现了“不相容原理”。泡利的发现揭示了原子内从未被发现的新规则。当时费米正在思考一种具有稳定特性的“理想”气体。这种理想气体按什么规律行事?它与泡利的新发现有什么关系?这些问题一直徘徊在费米的脑海里,久久没有得到解决。 In 1925, Pauli found the principle of “incompatibility.” Pauli’s discovery reveals new rules that have never been discovered within the atom. Fermi was thinking about an “ideal” gas with stable properties. How does this ideal gas behave? How does it relate to Pauli’s new discoveries? These questions have been stuck in Fermi’s mind for a long time.
