Idealist notions took a strong hold among physicists of the early 20th century confronted with the paradoxes of quantum physics and the theory of relativity. In The Grammar of Science, Preface to the 2nd Edition, 1900, Karl Pearson wrote, "There are many signs that a sound idealism is surely replacing, as a basis for natural philosophy, the crude materialism of the older physicists." This book influenced Einstein's regard for the importance of the observer in scientific measurements[citation needed]. In § 5 of that book, Pearson asserted that "...science is in reality a classification and analysis of the contents of the mind...." Also, "...the field of science is much more consciousness than an external world."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the theory of relativity first appear in?
Ah, so.. unanswerable

The islands have been shaped by numerous glaciations during the Quaternary Period, the most recent being the Devensian.[citation needed] As this ended, the central Irish Sea was deglaciated and the English Channel flooded, with sea levels rising to current levels some 4,000 to 5,000 years ago, leaving the British Isles in their current form. Whether or not there was a land bridge between Great Britain and Ireland at this time is somewhat disputed, though there was certainly a single ice sheet covering the entire sea.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): During this period, it is certain a land bridge existed between England and which country?
Ah, so.. unanswerable

The design of the Institute's Mycenean lions medal and the motto ‘Usui civium, decori urbium' has been attributed to Thomas Leverton Donaldson, who had been honorary secretary until 1839. The RIBA Guide to its Archive and History (Angela Mace,1986) records that the first official version of this badge was used as a bookplate for the Institute's library and publications from 1835 to 1891, when it was redesigned by J.H.Metcalfe. It was again redesigned in 1931 by Eric Gill and in 1960 by Joan Hassall. The description in the 1837 by-laws was: "gules, two lions rampant guardant or, supporting a column marked with lines chevron, proper, all standing on a base of the same; a garter surrounding the whole with the inscription Institute of British Architects, anno salutis MDCCCXXXIV; above a mural crown proper, and beneath the motto Usui civium decori urbium ".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the first Latin phrase used by the Royal Institute?
Ah, so..
Usui civium decori urbium
