It is common knowledge that crickets are leaping insects and that the males make chirping noises.
But, did you know crickets can do math?
According to researchers, crickets are finely attuned to fluctuations in air temperature because they are cold-blooded creatures and their rate of metabolism is determined by temperature. They have discovered that crickets chirp faster as the temperature climbs up the thermometer. To estimate the temperature in Fahrenheit, count the number of chirps in 15 seconds and add 39. This mathematical formula is believed to be accurate within one degree.
