If you are a hiker or camper, you may have heard about Vestergaard Frandsen’s LifeStraw. It’s a hollow stick equipped with a series of filtering membranes. You put the end of the stick in a river or puddle ─ or a toilet, for that matter ─ and suck on it. By the time the water hits your lips, it is clean and safe ─ its filters are fine enough to trap virtually all bacteria, viruses and parasites. The product has a bigger cousin called the LifeStraw Family. You hang it on your wall, pour dirty water in the top, open the tap and clean water comes out the bottom. No power or replacement parts are required. Each unit cleans about 18,000 liters of water ─ enough for a family for three years. The market cost of the unit averages out at a penny per ten liters of water purified. Vestergaard Frandsen will distribute the LifeStraw Family for free. It is helping to sponsor a traveling campaign through the western part of Kenya set for April, 2011, that will reach 4 million families. The campaign bundles various products ─ each family that attends will get insecticide-treated bednets to protect against malaria, AIDS tests and counseling and a free LifeStraw Family.

The Finnish fan club rarely talks about its mathematics performance in TIMSS, an international survey focusing more on curriculum-based knowledge – which plummeted over the last decade.

Others questioned whether it represents a victory at all since important knowledge had been sacrificed along the way.

while Finland scores well on PISA, this particular league table is designed to test everyday rather than curriculum-based knowledge. This means that it lacks key concepts of importance for further studies in mathematically intensive subjects, such as engineering, computer science, and economics. This is an obvious defect: such subjects are likely to be crucial for developed countries’ future economic well-being.
