 | "This new power, which has proved itself to be such a terrifying weapon of destruction, is harnessed for the first time for the common good of our community." - Queen Elizabeth II, upon opening Calder Hall nuclear power station on 17 Oct 1956.  |
 | "When I'm asked about the relevance to Black people of what I do, I take that as an affront. It presupposes that Black people have never been involved in exploring the heavens, but this is not so. Ancient African empires - Mali, Songhai, Egypt - had scientists, astronomers. The fact is that space and its resources belong to all of us, not to any one group." - Mae C. Jemison, (born 17 Oct 1956) |
 | "Lately we have been getting facts pointing to the 'oceanic' nature of the floor of so-called inland seas. Through geological investigations it has been definitely established that in its deepest places, for instance, the Caribbean Sea and the Gulf of Mexico, the Earth's crust is devoid of granite stratum. The same may be said quite confidently about the Mediterranean and the Black Sea. Could the interpretation of these data be that inland seas were the primary stage of the formation of oceanic basins?" - V. V. Belousov, Soviet geologist (born 17 Oct 1907) |
