The International Geophysical Year (IGY) was an international scientific effort which lasted from July 1957 to December 1958.
67 countries participated in total, performing experiments and research projects across 11 different Earth sciences such as meteorology, oceanography, seismology and geomagnetism; the most famous project was the launch of Sputnik 1, the world's first man-made satellite.
The IGY has been described as "the beginning of a new era of scientific discovery at a time when many innovative technologies were appearing", which certainly fits the song's theme of optimism about the future.

Founded in California in 1958, IHOP currently has nearly 2,000 locations across the US and Canada, plus a handful of international locations in Central America and the Middle East.
