Silent Spring

Examples of Silent Spring in the following topics:

• Environmental Protests

  • Organizations like The Sierra Club and Greenpeace, as well as the book "Silent Spring" by Rachel Carson, contributed to the growth of the environmental movement during this time period.
  • In 1962, American biologist Rachel Carson published Silent Spring, a book that is widely credited with helping launch the environmental movement.
  • In response to the publication of Silent Spring and the public concern that ensued, U.S.
  • In the mid-1970s, independent groups using the name Greenpeace started springing up worldwide.
  • Following the publication of Silent Spring and the public outcry it created, DDT was banned by the Environmental Protection Agency in June of 1972

• Biological Magnification

  • Many substances have been shown to bioaccumulate, including classical studies with the pesticide dichlorodiphenyltrichloroethane (DDT), which was published in the 1960s bestseller, Silent Spring, by Rachel Carson.

• The Arab Spring

• Springs

  • Spring force is conservative force, given by the Hooke's law : F = -kx, where k is spring constant, measured experimentally for a particular spring and x is the displacement .
  • We would like to obtain an expression for the work done to the spring.
  • The displacement x is usually measured from the position of "neutral length" or "relaxed length" - the length of spring corresponding to situation when spring is neither stretched nor compressed.
  • As the block slowly moves, we do work W on the spring: $W = \int_{0}^{x_f} (kx) dx = \frac{1}{2} k x_f^2$.
  • When we stretch the spring.

• Hooke's Law

  • For instance, the spring is pulled downwards with either no load, Fp, or twice Fp.
  • k is a constant called the rate or spring constant (in SI units: N/m or kg/s2).
  • It's possible for multiple springs to act on the same point.
  • The slope of this line corresponds to the spring constant k.
  • The extension of the spring is linearly proportional to the force.

• Simple harmonic oscillation

  • Figure 1.2 shows a mass suspended from a spring.
  • On the left, the mass and spring are in equilibrium.
  • For this spring we get 19 complete oscillations.
  • First compute the spring constant of the spring using the data above.
  • What you will find is that the spring constant is within a factor of 2 or 3 the same as the spring we used in class!

• Rest Length

  • Rests don't necessarily mean that there is silence in the music at that point; only that that part is silent.
  • As a simplifying shorthand, a completely silent measure can simply have a whole rest.
  • A whole rest may be used to indicate a completely silent measure, no matter what the actual length of the measure will be.

• Transposition Scorereading Assignment

  • Silently scan the first 8 bars.
  • The pause between repetitions should be silent, to allow you to think through how you did.
  • The pause between repetitions should be silent, to allow you to think through how you did.
  • Silently scan measures 9-16.

• The Miranda Warning

  • The Miranda warning is a statement read by police to criminal suspects that asserts their right to counsel and right to remain silent.
  • Merely remaining silent in face of protracted questioning is insufficient to assert the right.
  • The Miranda right to counsel and right to remain silent are derived from the self-incrimination clause of the Fifth Amendment.
  • If the defendant asserts his right to remain silent all interrogation must immediately stop and the police may not resume the interrogation unless the police have "scrupulously honored" the defendant's assertion and obtain a valid waiver before resuming the interrogation.
  • Merely remaining silent in face of protracted questioning is insufficient to assert the right.

• Culture in the Thirties

  • Charlie Chaplin, the greatest star of the silent era, successfully transitioned into the sound film.
  • Toklas, and Henry Miller, who in the 1930s wrote and published his semi-autobiographical novels Tropic of Cancer, Black Spring, and Tropic of Capricorn.
