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.
In its annual poverty report, the Census Bureau includes a table that few take note of which actually details by how much families are below the poverty line. A little multiplication and addition later, and the magic number pops out. In 2012, the number was $175.3 billion. That is how many dollars it would take to bring every person in the United States up to the poverty line. In 2012, that number was just 1.08 percent of the nationâs gross domestic product (GDP), which is to say the overall size of the economy.
