Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is transverse to the direction of motion of the wave, so the oscillations can have different directions perpendicular to the wave direction. A simple example of a polarized transverse wave is vibrations traveling along a taut string; for example, in a musical instrument like a guitar string. Depending on how the string is p
The Future of Poverty: Framing Uncertainty 75 Given both the weak basis for forecasting and slow change historically in domestic distributions, a fundamentally ï¬ at forecast is a reasonable pattern for the base case.8 Patterns of Potential Human Progress Volume 1: Reducing Global Poverty Third, however, those scenarios also remind us that the future is not simply a matter of different human action patterns.
Most Americans will spend at least one year below the poverty line at some point between ages 25 and 75. Poverty rates are persistently higher in rural and inner city parts of the country as compared to suburban areas. In 2015, 13.5% (43.1 million) Americans lived in poverty. Starting in the 1930s, relative poverty rates have consistently exceeded those of other wealthy nations. The lowest poverty rates are found in New Hampshire, Vermont, Minnesota and Nebraska, which have between 8.7% and 9.1% of their population living in poverty.
