(Color in online edition) Rod with ends at two different temperatures $T_1$ and $T_2$: (a) normal state; (b) superconducting state. Thermoelectric current ${\mathbf{j}}_{\mathrm{n}}$ is present in the supercon-ducting state. According to 19.

Figure 8

(Color in online edition) Plates of two different superconductors fused (soldered) together, whose juncture is an alloy, in the presence of a temperature gradient. Thermoelectric current $\mathbf{j}$ is detectable via the magnetic field $\mathbf{H}$, which is perpendicular to the junction line. According to 20.

The author, V. L. Ginzburg, at the weekly seminar he held at the Fizicheskii Institut Academii Nauk (FIAN, the P. N. Lebedev Physical Institute of the Academy of Sciences) over many years. This seminar on theoretical physics, which became rather famous for its lively exchange of information and ideas, was as enjoyable for the teacher as for the participants. By the time of its last session on November 21, 2001, it had met 1700 times.
