Bathed in polarized light and cut in cross section, this ancient ice reveals itself as a mosaic of colors, each one showing how conditions at depth in the ice have affected this material at depths where pressures can reach a ton per square inch.

And in addition, we've actually used polarizers on all the lights just like polarized sunglasses can block the glare off of the road, polarizers can block the shine off of the skin, so we don't get all those specular reflections to take this map.

Business leaders, long afraid to participate in such a polarized debate, have finally entered the fray, arguing forcefully that immigration is critical to American competitiveness.

The perspectives of proponents and opponents are so polarized that it is hard not to be utterly confused about the likely consequences. To appreciate what is at stake, we have to understand that these deals are motivated by a mix of objectives some benign, others less so from a global perspective.

Moreover, the ideological extremes that excited and polarized the continent back then are hardly in vogue today. Discredited by the collapse of the USSR and the Soviet bloc in Eastern Europe, communism is effectively moribund, and its core constituencies where communist parties manage to hang on are aging and incapable of reproducing themselves.

But Morsi s narrow margin of victory (just 3.5 percentage points) over Shafiq, and low voter turnout 46.4 in the first round and 51.8 in the second reflect a polarized, exhausted society that lacks confidence in the electoral process and the candidates.

In the US, polarized politics, gerrymandered Congressional districts, and a constitution that seems to check more than it balances, have obstructed reforms and left the country seemingly adrift in choppy waters. The middle class is being hollowed out, and failed overseas adventures have discouraged the once indispensable nation from bearing the burden of global leadership.

In his six years in office, he has repeatedly tried to bypass a polarized state legislature even the annual budget requires a two thirds majority by appealing directly to voters. Ballot initiatives were created 100 years ago to empower ordinary citizens, but in recent decades the process has been captured by self serving elites.

Moreover, though party politics have become more polarized in recent decades, this follows the 1950s and early 1960s, when the escape from the Great Depression and victory in World War II fueled unusually high confidence in US institutions.

If the US pursues a predominantly confrontational approach, East Asian politics will inevitably become polarized, just as multipolar nineteenth century Europe gave way to an increasingly bipolar order in lockstep with rising tensions between Germany and Britain.
