In 1830, Thaddeus Fairbanks invented the first platform balance scale and opened a business with his brother, Erastus.
Prior to moving into the house built for Jonathan, Grace and their six children, the family lived for several years in Watertown, Massachusetts .The Opposed Piston engine was developed in the mid-1930s and was initially used to power submarines and locomotives.Because of the outstanding reliability derived from the design, Opposed Piston engines are still in service on U. Navy ships, in electric power plants, and in numerous mechanical drive applications.It is estimated that nearly 90% of all measurements made at the more than 50 active accelerator mass spectrometry laboratories are radiocarbon dates.
This dramatic increase in the number of radiocarbon dates is driving the demand for a radiocarbon calibration program that spans the entire radiocarbon timescale from the present to 55,000 years BP.
