Tacoma Narrows Bridge (1940) Billah and Scanlan (1991) reported that in fact, many physics textbooks (for example Resnick et al. and Tipler et al.) wrongly explain that the cause of the failure of the Tacoma Narrows bridge was externally forced mechanical resonance. Resonance is the tendency of a system to oscillate at larger amplitudes at certain frequencies, known as the system's natural frequencies. At these frequencies, even relatively small periodic driving forces can produce large amplitude vibrations, because the system stores energy. For example, a child using a swing realizes that if the pushes are properly timed, the swing can move with a very
Some Girls Are Bigger Than Others embrace," while Nick Kent wrote, "'Vicar In a Tutu' and 'Some Girls Are Bigger Than Others', sensibly restrained arrangement-wise, may well be lesser songs but, constructed within their rightful limitations, sound absolutely stunning". In Simon Goddard's track-by-track book "", Johnny Marr describes the song as "a beautiful piece of music", while the author writes, "Possessing one of his most alluring guitar melodies [...] if Marr's tune was heaven-sent, then it seemed very nearly blasphemous of Morrissey to christen it 'Some Girls Are Bigger Than Others' and bestow it with its notoriously frivolous lyric".
