Why Is My Whiteboard So Dirty?

A cylinder of air reaching to the top of the atmosphere is of equal weight with a cylinder of water about 33 feet high. ~ Isaac Newton 1642 to 1727

Although the alternate ‘wax and wane’ cycles are the rule rather than the exception in all fields of human endeavor in that of biological sciences the ‘wane’ is all too often indicative of a justified loss of faith in the rational and methodical approach that had at first raised so much hope. ~ Rita Levi-Montalcini 1909 to 2012 Neurobiologist

Brilliant Quotes By Famous And Awesome Scientists!

In practical applications we are concerned only with comparatively small numbers; only stellar astronomy and atomic physics deal with ‘large’ numbers and they have very little more practical importance as yet than the most abstract pure mathematics. ~ G. H. Hardy 1877 – 1947 - Mathematician

Geometry inasmuch as it is concerned with real space is no longer considered a part of pure mathematics; like mechanics and physics it belongs among the applications of mathematics. ~ Hermann Weyl 1885 to 1955 - Mathematician and Theoretical Physicist

Division is esteemed one of the busiest operations of Arithmetic and such as requireth a mind not wandering or settled upon other matters. ~ Thomas Hylles The arte of vulgar arithmeticke 1600 - Mathematician

Surely it is not knowledge but learning; not owning but earning; not being there but getting there; that gives us the greatest pleasure. ~ Carl Friedrich Gauss 1777 – 1855 - Mathematician and Physicist

Chemistry is necessarily an experimental science: its conclusions are drawn from data and its principles supported by evidence from facts. ~ Michael Faraday - 1791 to 1867

The ultimate truths of mathematics then cannot be established by any experimental proof that the deductions from them are true; since the supposed experimental proof takes them for granted. ~ Herbert Spencer 1885 – 1977 - Philospher

Actually everything that can be known has a Number; for it is impossible to grasp anything with the mind or to recognize it without this. - Philolaus c. 470 – c. 385 BC Scientist and Philosopher
