Whites (mainly of Afrikaner, German, British and Portuguese origin) make up between 4.0 and 7.0% of the population. Although their percentage of population is decreasing due to emigration and lower birth rates they still form the second-largest population of European ancestry, both in terms of percentage and actual numbers, in Sub-Saharan Africa (after South Africa). The majority of Namibian whites and nearly all those who are mixed race speak Afrikaans and share similar origins, culture, and religion as the white and coloured populations of South Africa. A large minority of whites (around 30,000) trace their family origins back to the German settlers who colonized Namibia prior to the British confiscation of German lands after World War One, and they maintain German cultural and educational institutions. Nearly all Portuguese settlers came to the country from the former Portuguese colony of Angola. The 1960 census reported 526,004 persons in what was then South-West Africa, including 73,464 whites (14%).
How much of the population was white in South-West Africa in 1960?
73,464

Ultimately, the New Orthophonic curve was disclosed in a publication by R.C. Moyer of RCA Victor in 1953. He traced RCA Victor characteristics back to the Western Electric "rubber line" recorder in 1925 up to the early 1950s laying claim to long-held recording practices and reasons for major changes in the intervening years. The RCA Victor New Orthophonic curve was within the tolerances for the NAB/NARTB, Columbia LP, and AES curves. It eventually became the technical predecessor to the RIAA curve.
Who developed the New Orthophonic curve?
RCA Victor

The neopositivists subscribed to a notion of philosophy as the conceptual clarification of the methods, insights and discoveries of the sciences. They saw in the logical symbolism elaborated by Frege (18481925) and Bertrand Russell (18721970) a powerful instrument that could rationally reconstruct all scientific discourse into an ideal, logically perfect, language that would be free of the ambiguities and deformations of natural language. This gave rise to what they saw as metaphysical pseudoproblems and other conceptual confusions. By combining Frege's thesis that all mathematical truths are logical with the early Wittgenstein's idea that all logical truths are mere linguistic tautologies, they arrived at a twofold classification of all propositions: the analytic (a priori) and the synthetic (a posteriori). On this basis, they formulated a strong principle of demarcation between sentences that have sense and those that do not: the so-called verification principle. Any sentence that is not purely logical, or is unverifiable is devoid of meaning. As a result, most metaphysical, ethical, aesthetic and other traditional philosophical problems came to be considered pseudoproblems.
What did Wittgenstein say about logic?
all logical truths are mere linguistic tautologies
