The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to close to absolute zero, i.e. –273.15 °C, −459.67 °F or 0 K). [1] It also lists important milestones in thermometry , thermodynamics , statistical physics and calorimetry , that were crucial in development of low temperature systems.
Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...

Attention deficit hyperactivity disorder management options are evidence-based practices with established treatment efficacy for ADHD.Approaches that have been evaluated in the management of ADHD symptoms include FDA-approved pharmacologic treatment and other pharmaceutical agents, psychological or behavioral approaches, combined pharmacological and behavioral approaches, cognitive training ...
This timeline includes developments in subfields of condensed matter physics such as theoretical crystallography, solid-state physics, soft matter physics, mesoscopic physics, material physics, low-temperature physics, microscopic theories of magnetism in matter and optical properties of matter and metamaterials.

Hyperactivity has long been part of the human condition, although hyperactive behaviour has not always been seen as problematic. [1] [page needed]The terminology used to describe the symptoms of attention deficit hyperactivity disorder, or ADHD, has gone through many changes over history, including "minimal brain damage", "minimal brain dysfunction", "learning/behavioral disabilities" and ...
