Spirit of the Dead Watching her fear. Mathews says it is too simple to attribute Tehura's terror to her belief in spirits and irrational fear of the dark; she says, following Sweetman, that Gauguin's sexual predilections should not be ignored when trying to understand the work. Rather, she suggests the girl's fear was a response to Gauguin's aggressive behavior, consistent with his known battering (so says Mathews) of his wife Mette, the submissive fear in her eyes his erotic reward. Stephen F. Eisenman, professor of Art History at Northwestern University, suggests the painting and its narrative is "a veritable encyclopaedia of colonial racism and misogyny".
Proof that e is irrational Proof that e is irrational The number "e" was introduced by Jacob Bernoulli in 1683. More than half a century later, Euler, who had been a student of Jacob's younger brother Johann, proved that "e" is irrational; that is, that it cannot be expressed as the quotient of two integers. Euler wrote the first proof of the fact that "e" is irrational in 1737 (but the text was only published seven years later). He computed the representation of "e" as a simple continued fraction, which is Since this continued fraction is infinite and every rational number has a terminating continued
