You might be surprised to find, however, that the first seismometer was invented in China in 132 AD by a Chinese astronomer, mathematician, engineer, and inventor called Zhang Heng. The instrument was said to resemble a wine jar six feet in diameter, with eight dragons positioned face down along the outside of the barrel, marking the primary compass directions. In each dragon’s mouth was a small bronze ball. Beneath the dragons sat eight bronze toads, with their broad mouths gaping to receive the balls. When the instrument sensed an incoming seismic wave, one of the balls would drop and the sound would alert observers to the earthquake, giving a rough indication of the earthquake’s direction of origin. The device is said to have been very accurate and could detect earthquakes from afar, and did not rely on shaking or movement in the location where the instrument was positioned. The first ever earthquake recorded by this seismograph was supposedly somewhere in the east. Days later, a rider from there reported this earthquake. Moreover, it had the most wicked ornaments. They don’t make scientific instruments like they used to! Of course, the insides of the seismometer was filled with a sensing mechanism of some sort, the contents of which have been lost in time. In all likelihood, a simple or inverted pendulum was employed, according to experts.

Answer: The Center for disease control and prevention (CDC) uses the Body Mass Index(BMI) to determine categories of overweight and at risk for being overweight
Explanation: BMI is defined as the body mass of an individual divided by the square of their height.
The BMI is used to categorize a person as underweight, normal weight, overweight, or obese based on the ratio of their body mass to the square of their height.
Underweight are categorised to have a BMI of under 18.5, normal weight has a range of 18.5 to 25, overweight has a range of 25 to 30, and obese over 30. The unit for the BMI is the kg/m²
