Chemistry unlike other sciences sprang originally from delusions and superstitions and was at its commencement exactly on a par with magic and astrology. ~ Thomas Thomson - 1773 to 1852
Did the genome of our cave-dwelling predecessors contain a set or sets of genes which enable modern man to compose music of infinite complexity and write novels with profound meaning? …It looks as though the early Homo was already provided with the intellectual potential which was in great excess of what was needed to cope with the environment of his time.” - Susumu Ohno 1928 to 2000 Geneticist

The legend that every cipher is breakable is of course absurd though still widespread among people who should know better. ~ J.E. Littlewood 1885 – 1977 - Mathematician
We are storytelling animals and cannot bear to acknowledge the ordinariness of our daily lives. - Stephen Jay Gould 1941 to 2002 Paleontologist
Primates are visual animals above all and anatomical work in particular is as much pictorial as verbal. ~ Stephen Jay Gould 1941 to 2002 - Paleontologist
Outstanding examples of genius – a Mozart a Shakespeare or a Carl Friedrich Gauss – are markers on the path along which our species appears destined to tread. - Fred Hoyle 1915 to 2001 Astrophysicist
Macroscopic objects as we see them all around us are governed by a variety of forces derived from a variety of approximations to a variety of physical theories. In contrast the only elements in the construction of black holes are our basic concepts of space and time. They are thus almost by definition the most perfect macroscopic objects there are in the universe. ~ Subrahmanyan Chandrasekhar 1910 to 1995
I see some parallels between the shifts of fashion in mathematics and in music. In music the popular new styles of jazz and rock became fashionable a little earlier than the new mathematical styles of chaos and complexity theory. Jazz and rock were long despised by classical musicians but have emerged as art-forms more accessible than classical music to a wide section of the public. Jazz and rock are no longer to be despised as passing fads. Neither are chaos and complexity theory. But still classical music and classical mathematics are not dead. Mozart lives and so does Euler. When the wheel of fashion turns once more quantum mechanics and hard analysis will once again be in style. ~ Freeman Dyson b. 1923 - Mathematician and Physicist
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
