Women in ancient Sparta their wealth. He attributed the state's precipitous fall during his lifetime, from being the master of Greece to a second-rate power in less than 50 years, to the fact that Sparta had become a gynocracy whose women were intemperate and loved luxury. All Spartan women, not just the richest, would have taken advantage of helot labour to perform the domestic tasks that elsewhere in Greece would have fallen to free women. Activities such as weaving which were considered women's work elsewhere in Greece were not considered fit for free women in Sparta. Therefore, women were more preoccupied with governance, agriculture,
SERF SERF A spin exchange relaxation-free (SERF) magnetometer is a type of magnetometer developed at Princeton University in the early 2000s. SERF magnetometers measure magnetic fields by using lasers to detect the interaction between alkali metal atoms in a vapor and the magnetic field. The name for the technique comes from the fact that spin exchange relaxation, a mechanism which usually scrambles the orientation of atomic spins, is avoided in these magnetometers. This is done by using a high (10 cm) density of potassium atoms and a very low magnetic field. Under these conditions, the atoms exchange spin quickly compared to
