| Quotations for Today | |
| "Mathematics education is much more complicated than you expected, even though you expected it to be more complicated than you expected." - Edward Griffith Begle, American Mathematician who led development of "new math" (born 27 Nov 1914) "It soon became obvious that we were but on the threshold of the discovery..." (We saw) "...a sealed doorway between the two guardian statues of the King, the mystery gradually dawned upon us. We were but in the anterior portion of a tomb. Behind that closed doorway was the tomb- chamber ... We then examined the plaster and seal-impressions upon the closed doorway. ... all bearing the insignia of the King." - Howard Carter in his excavation notes for 27 Nov 1922, upon entering the Antechamber of the tomb of King Tutankhamun. (About the enigma of the sea) "A hundred chemicals and a million living sparks and a billion bits of drift, no two alike ... an endless, moving, thin, transparent soup; a cosmic stock forever old and ever new." - Victor B. Scheffer, American marine zoologist (born 27 Nov 1906) (source) | |

He developed the Giorgi International System of Measurement in 1901. Originally, he suggested that the basic units of scientific measurement be the metre, kilogram, second, and joule. In 1960, this system was subsequently endorsed by the General Conference of Weights and Measures, though the joule was replaced by another basic unit. What unit replaced the joule? | |
