Happy birthday to Jean Baptiste Biot (born in Paris on this day in 1774)
Bon anniversaire à Jean Baptiste Biot (né à Paris aujourd'hui en 1774)
Biot is more usually known for his work, with his colleague Félix Savart at the Collège de France, Paris on electromagnetism and the Biot-Savart law first published in 1820.
This law relates the strength of a magnetic field to distance and the electric field current vector from a (closed circuit) steady electrical current. This helped lay the foundations of James Clerk Maxwell’s extensive work on electromagnetic radiation, and the ‘Maxwell Equations’ of 1865
More relevant to our research interests, Biot investigated the meteorite fall of 26th April 1803 near to L’Aigle (Normandy, France). His analysis was pivotal in the proof and acceptance of the extra-terrestial nature of meteorites, together with their association with fireball meteors.
Biot est connu pour le travail qu'il a fait au Collège de France avec Félix Savart sur l'électromagnétisme, et la loi de Biot et Savart (1820).
Cette loi donne le champ magnétique créé par une distribution de courants continus et constitue l'une des lois fondamentales de la magnétostatique. Elle a jetté les fondements du travail de James Clerk Maxwell sur le rayonnements électromagnétiques et les équations de Maxwell (1865).
Mais ce qui nous intéresse surtout, c'est que Biot a étudié la chute de la météorite du 26 avril 1803 près de L'Aigle (Normandie, France). Son analyse a démontré l'origine extraterrestre des météorites et leur lien avec les boules de feu météoriques
20th April: Update on our location
As previously mentioned, Observatoire Solaire is on the move. We are relocating from Scotland and our initial intention was to relocate completely to France. However, due to personal reasons and the UK’s potential withdrawal from the European Union (and commensurate ill-defined citizen, residence and work status) we will be establishing a presence in both the UK and France.
In the UK, we are relocating to North Yorkshire, just south of the city of York. In France, we are looking at sites within Limousin and Creuse and will be assessing these during our current spring field trip.
And of course the good news is that we will be able to continue our work in both countries.
Whilst Observatoire Solaire normally seeks to maintain a neutral political perspective, we are pleased to be able to affirm we are strong proponents of the European Union. We consider the approach being taken by the current UK administration to be political, economic and social cohesion folly, and an affront to citizen’s rights (UK and continental mainland born). We are a ‘remain’ business, and are proud to be members of ‘Scientists for EU’. Our ability to easily work in both the UK and France is jeopardised.
Please note, whereas individual members of our staff are happy to debate views, we will not engage in political discussion on this page, and overt political comments will be removed. Our statement above is for information only.
On April 17th we will be undertaking a field trip to Haute-Vienne (the region near Rochechouart) to progress and further research our investigations into the Limousin asteroid impact of the Rhaetian age.
As we will be in France during April and May, if any of our France based colleagues would like to avail themselves of our current offers on our publications, these will be dispatched to you (from France) without postal surcharges being required. Please see our shop for details. If ordering for delivery within France, there is currently no requirements for international postage for orders shopped after 17th April. (UK purchasers can continue to order as normal)
