The lowest temperature ever recorded at the surface of the earth was −89.2 °C (184.0 K) at the Soviet Vostok Station in Antarctica July 21, 1983. Back cover: “The coldest place on earth”. In 1908 Kamerlingh Onnes at the University of Leiden, Dept. of Physics, managed to lower the temperature to less than four degrees above absolute zero, to −269 °C (4.15˚ Kelvin). The absolute zero is set by international agreement at -273.15 degrees Celsius. Photo with permission form Leiden University.

In A.D 47 he described the use of electrical energy to treat some forms of pain by using the torpedo fish. Torpedo stems from Latin “torpere”, meaning “paralyzing or stiffening” and refers to the effects after human contact with the fish. The fish was used by the Greek to treat pain during childbirth and operations (Lazorthes et al., 1985; Bullock et al., 2005). Neuromodulation is a recognized invasive therapy since its introduction in 1967 (Shealy et al., 1967). Two types are recognized in chronic non- oncological pain patients: Spinal Cord Stimulation (SCS) or Dorsal Column Stimulation (DCS), and the intrathecal administration of morphine (Spincemaille et al., 2004; Theuvenet et al., 2005). Torpedo fish (Genus Torpedinidae) Our clinical observation that after electrical dorsal traumatic peripheral nerve injury produces sensory column stimulation in some patients with chronic disturbances and a volley of impaired afferent non-oncological pain, the pain alleviating effect information (Woolf, 1993; Dellemijn, 1997; Woolf diminished over time, triggered this research and Mannion, 1999), had to have demonstrable project. Besides the well known causes like scar functional cortical effects. The study of both issues tissue around the electrode, electrode migration started in 1993. The first magnetoencephalograph and change in the course of the underlying (MEG) in The Netherlands was manufactured disease, the therapy failed in some patients for and made available for research at the Low unknown reasons.
