Photonic Structure Increases Light Bulb Efficiency

An Anonymous Coward writes "A new experimental microscopic tungsten lattice can increase the efficiency of an incandescent electric bulb from 5 percent to greater than 60 percent. This is done by converting waste heat into visible light. "

No such thing as a "USian". Let's settle this.

There's no such thing as a USian.

You see, some countries in the world are called "The United States of X". Generally because, accurately or otherwise, they're supposedly a federal union of autonomous "states".

People who live in one of these "United States" countries are called after the place where the states are located.

Citizens of the United States of Mexico are called.... Mexicans.

Citizens of the United States of Brazil are called.... Brazilians.

Citizens of the United States of America are called.... Americans.

But the entire Western Hemisphere should be called "America"! It's unfair that just the USA uses that name!

Unfair in what way? Brazil doesn't lack a name. Canada's not hurting for a moniker unrelated to the name of its continent.

Besides, geographical names are blurry anyway. By "Africa'' a lot of people mean simply "sub-Saharan Africa". Peru used to mean all of non-Brazilian South America, not just one Andean country. Some names (e.g. Iraq, Pakistan) are simply made up out of nowhere.

So why invent the ugly term "USian", which could equally well apply to several different countries, when everybody the world over knows what an "American" is?
