James Hargreaves James Hargreaves James Hargreaves (c. 1720 – 22 April 1778) was a weaver, carpenter and inventor in Lancashire, England. He was one of three inventors responsible for mechanising spinning. Hargreaves is credited with inventing the spinning jenny in 1764, Richard Arkwright patented the water frame in 1769, and Samuel Crompton combined the two creating the spinning mule in 1779. James Hargreaves was born at Stanhill, Oswaldtwistle in Lancashire. He was described as "stout, broadest man of about five-foot ten, or rather more". He was illiterate and worked as a hand loom weaver during most of his life. He married and
Spinning dust Spinning dust In astronomy, spinning dust is a mechanism proposed to explain anomalous microwave emission from the Milky Way. The emission could arise from the electric dipole of very rapidly spinning (10–60 GHz) extremely small (nanometer) dust grains (Draine & Lazarian 1998), most likely polycyclic aromatic hydrocarbons. The anomalous emission was first discovered as a by-product of Cosmic Microwave Background observations which make very sensitive measurements of the microwave sky which have to identify and remove contamination from the galaxy. Anomalous microwave emission was first seen as a surprising statistical correlation of microwave sky variations with far infrared (FIR) emission
