Part 3/7:
Grignia began by referencing the work of physicist Y.A. Zeldovich, who introduced the concept of the anapole in 1957. The anapole refers to a magnetic configuration, leading Grignia to ponder its significance in contemporary research, particularly regarding how these toroidal moments are perceived in modern physics. He emphasized that the understanding of anapoles and toroidal moments remained obscure until the late 1990s when the Western scientific community recognized their importance, predominantly in relation to the multipole expansions of electromagnetic fields.
