...or color can represent time, as in this map of 4 years of light echoes from V838 Mon, a brilliant explosion caused by the collision of a pair of massive stars.

Fuelling Sentinel-1C

Marking a major milestone in the preparation of Copernicus Sentinel-1C for its scheduled 3 December liftoff, experts have completed the critical and hazardous process of fuelling the satellite.

Once in orbit, Sentinel-1C will extend the Sentinel-1 mission’s legacy, delivering radar imagery to monitor Earth’s changing environment to support a diverse range of applications and scientific research. Additionally, Sentinel-1C brings new capabilities for detecting and monitoring maritime traffic

Peut-on remplacer les pollinisateurs ?

Peut-on remplacer les #pollinisateurs ?

Depuis des millions d’années, les plantes et leurs pollinisateurs renouvellent au quotidien leurs vœux d’amour fou et indestructible, s’adaptant en permanence les uns aux autres avec une finesse inouïe. Mais le nombre d’insectes susceptibles de polliniser tomates, pommes et framboises ne cesse de reculer. Que faire si ces vœux de fidélité sont remis en cause : https://www.arte.tv/fr/videos/115511-006-A/peut-on-remplacer-les-pollinisateurs/

Note : je n'apprécie pas spécialement la présentation du programme mais j'attire votre attention sur l'importance des pollinisateurs sauvages qui est assez bien relevée ici notamment avec de l'exemple de l'#abeille...

Bounce theory

I imagined subatomic particles interacting with each other within the diffuse confines of nuclei.These atomic entities occupy space-time by engaging in oscillatory activity. One could say they are "bouncing" in space-time.

Imagine a balloon that has been filled with small, light plastic balls. The balloon is then inflated and placed under a piece of cloth that is in constant oscillation. The oscillations of the cloth produce small jumps in the balloons, which in turn produce movement of its inner elements. The angle, force and frequency of bounces of the balloons on the cloth would all determine the position of the smaller elements. The combination of the aforementioned variables is non-deterministic, but the individual principles involved in the oscillation of the cloth, the bounce of the balloon, and the movement of its inner particles, are deterministic.

The principles that determine the motion of subatomic particles are deterministic, but the "bounces" aren't, because the fabric of space-time oscillates as well, making the point of bounce random. This could account for why deterministic principles are hard to apply to the measurement of position in time and space of subatomic particles. We are not taking into account the "bounce"
