Researchers in Australia have developed the world’s most sensitive thermometer—and it measures temperature with a precision of 30 billionths of a degree using the properties of a circle! Read the article here.
The Mars Orbiter was lost in 1999 because the Nasa team used imperial units while a contractor used metric. The $125m probe came too close to Mars during its orbit and was probably destroyed by the planet’s atmosphere.
