millimeter / millimetre
	A single-seat jet fighter mounting four 20-millimeter
	cannon was undergoing new tests in Argentina last week,
	after whistling through a first trial flight clocked

	numerical

	quadruple
	A little math shows that 13.9 percent
	of this age group has contracted the illness,
	but that the case-hospitalization rate is 0.45 percent

	that of children.
	quota
	In 2007 it took two days for the government
	to receive enough applications to fill
	the quota of 65,000 regular H-1B visa permits
	for foreign skilled workers; in 2008 it took one.
	semiconductor
	Since then the semiconductor giant has recovered
	much of the mojo that was in question in the mid-2000s,

	As the director of mind-body medicine for a cancer center
	that offers seminars on how patients can benefit
	from this emerging science, I can attest that most
	have never heard of epigenetics.
	trigonometry
	I remember walking to trigonometry class
	on a sunny morning, looking up at the blue sky
	and seeing a police officer stationed on
	the roof of our language-arts building.
	trillion
	Ivars Peterson, director of publications
	at the Mathematical Association of America,
	after a computer scientist computed the mathematical
	constant pi to nearly 2.7 trillion digits.
