This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
A study presents results of a Riyadh-based trial of eight urban heat mitigation scenarios, finding large cooling effects with combinations that include reflective rooftop materials, irrigated greenery, and retrofitting. [33] [34] 12 January. Global warming: 2023 is confirmed as the hottest year on record by several science agencies. [35]
1820: Hans Christian Ørsted discovers that a current passed through a wire will deflect the needle of a compass, establishing the deep relationship between electricity and magnetism (electromagnetism). 1820: Michael Faraday and James Stoddart discover alloying iron with chromium produces a stainless steel resistant to oxidising elements .
1669 — Honoré Fabri suggested using a temperature scale by dividing into 8 equal parts the interval between "greatest heat of summer" and melting snow. [ 3 ] 1676 to 1679 — Edme Mariotte conducted experiments that under the French Academy of Science ’s Paris Observatory , resulting in wide adoption of temperatures of deep cellars as a ...
The general pathway to thermotolerance is characterized by sensing of heat stress, activation of HSFs, upregulation of heat response, and return to the non-stressed state. [ 7 ] In 2011, while studying heat stress A. thaliana , Ikeda et al. concluded that the early response is regulated by HsfA1 and the extended response is regulated by HsfA2.
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
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.
Researchers from the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) report a new way to stabilise the "tearing modes" in fusion reactors, using radio waves to create small changes in the temperature of the plasma, allowing it to be controlled more easily.
