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
Baptism for the dead something that Marcion denied, and that, in fact, "baptized for the dead" means baptized for the body destined to die and rise again. Somewhat similarly, John Chrysostom explained Paul's mention of people being "baptized for the dead" as a reference to the profession of faith they made in their own future resurrection before being baptized. Some interpret "baptized for the dead" as a metaphor for martyrdom, as in and baptism is a metaphor for suffering or martyrdom; accordingly they would translate it as "being baptized with a view to death". In this interpretation, the phrase is closely linked with what
