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.
Exchange of strikes between Israel and Lebanese militant group Hezbollah have been occurring along the Israel–Lebanon border and in Syria and the Israeli-occupied Golan Heights since 8 October 2023. It is currently the largest escalation of the Hezbollah–Israel conflict to have occurred since the 2006 Lebanon War, and part of the spillover ...
Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
Geography of Lebanon. Lebanon is a small country in the Levant region of the Eastern Mediterranean, located at approximately 34˚N, 35˚E. It stretches along the eastern shore of the Mediterranean Sea and its length is almost three times its width. From north to south, the width of its terrain becomes narrower.
Mesoscale meteorology is the study of weather systems and processes at scales smaller than synoptic-scale systems but larger than microscale and storm-scale. Horizontal dimensions generally range from around 5 kilometres (3 mi) to several hundred kilometres. Examples of mesoscale weather systems are sea breezes, squall lines, and mesoscale ...
Field (physics) Illustration of the electric field surrounding a positive (red) and a negative (blue) charge. In science, a field is a physical quantity, represented by a scalar, vector, or tensor, that has a value for each point in space and time. [1][2][3] A weather map, with the surface temperature described by assigning a number to each ...
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 Lorentz self-force derived for non-relativistic velocity approximation , is given in SI units by: = ˙ = ˙ = ˙ or in Gaussian units by = ˙. where is the force, ˙ is the derivative of acceleration, or the third derivative of displacement, also called jerk, μ 0 is the magnetic constant, ε 0 is the electric constant, c is the speed of light in free space, and q is the electric charge of ...
