François Arago
  26/02/1786 (Estage)
       2/101853

    Mathematician




                        François Arago by Steuben (1832)
He entered the « école polytechnique » in
1803, he was seventeen
The Emperor Napoléon asked
Arago to work about the earth
meridian
Arago did a lot of research,
   especially in astronmy.
   His work lead to great progress in
   optic and in electro-magnétism

   Arago studied geodesy,
   geometry, machine theory,
   astronomy and physic.

He is the first french scientist awarded with the copley's medal
Bernard Lyot


Inventeur du coronographe
Born the 27/02/1897 in paris
Bernard Lyot build a small
observatory in his home for his own
experiments. He meets Alfred Perot
who allow him to study in “école
polytechniques”.




                                      Alfred Perot
During the first world war, Bernard Lyot developped
radionavigation, still used nowadays by ships and planes.


La radionavigation est une technique de navigation utilisant des ondes radioélectriques
pour déterminer sa position ou un lieu de position. Les points obtenus sont indépendants
des conditions de visibilité.
Bernard Lyot with the help of Alfred Pero compared the surfaces of the
solar system plantets
A coronagraph is a device which blocks light
from the center of the telescope beam while
permitting light from surrounding sources to
pass through relatively undisturbed.

                   Lyot crater on Mars, (Latitude : 30° N to

(2452) Lyot astéroid
most names given to the astéroids sitiuated in the belt
between Mars and Jupiter planets, belongs to scientist
whom work helped to improve human knowledge in
astronomy.
Pierre-Simon, marquis de Laplace,
(b. March 23, 1749, Beaumount-en-Auge, Normandy, France—d. March 5, 1827, Paris),




                                Laplace was the son of a peasant farmer. French
                                mathematician, astronomer, and physicist who is
                                best known for his investigations into the stability of
                                the solar system.

                                Laplace successfully accounted for all the observed
                                deviations of the planets from their theoretical orbits
                                by applying Sir Isaac Newton’s theory of gravitation
                                to the solar system, and he developed a conceptual
                                view of evolutionary change in the structure of the
                                solar system. He also demonstrated the usefulness
                                of probability for interpreting scientific data.

COMENIUS - Présentation d'astronome français célèbres

  • 1. Estelle deve Anais basset Reda Gaid Lucie Fernandes Eloise masfrand Lise Mannier
  • 3. François Arago 26/02/1786 (Estage) 2/101853 Mathematician François Arago by Steuben (1832)
  • 4. He entered the « école polytechnique » in 1803, he was seventeen
  • 5. The Emperor Napoléon asked Arago to work about the earth meridian
  • 6. Arago did a lot of research, especially in astronmy. His work lead to great progress in optic and in electro-magnétism Arago studied geodesy, geometry, machine theory, astronomy and physic. Planets diameters
  • 7. He is the first french scientist awarded with the copley's medal
  • 10.
  • 11. Bernard Lyot build a small observatory in his home for his own experiments. He meets Alfred Perot who allow him to study in “école polytechniques”. Alfred Perot
  • 12. During the first world war, Bernard Lyot developped radionavigation, still used nowadays by ships and planes. La radionavigation est une technique de navigation utilisant des ondes radioélectriques pour déterminer sa position ou un lieu de position. Les points obtenus sont indépendants des conditions de visibilité.
  • 13. Bernard Lyot with the help of Alfred Pero compared the surfaces of the solar system plantets
  • 14.
  • 15. A coronagraph is a device which blocks light from the center of the telescope beam while permitting light from surrounding sources to pass through relatively undisturbed.
  • 16.
  • 17. Télescope Bernard Lyot Lyot crater on the moon [50,2S, 84,1E] Lyot crater on Mars, (Latitude : 30° N to 65° N. Longitude : 360° W to 300° W.) (2452) Lyot astéroid most names given to the astéroids sitiuated in the belt between Mars and Jupiter planets, belongs to scientist whom work helped to improve human knowledge in astronomy.
  • 18. Pierre-Simon, marquis de Laplace, (b. March 23, 1749, Beaumount-en-Auge, Normandy, France—d. March 5, 1827, Paris), Laplace was the son of a peasant farmer. French mathematician, astronomer, and physicist who is best known for his investigations into the stability of the solar system. Laplace successfully accounted for all the observed deviations of the planets from their theoretical orbits by applying Sir Isaac Newton’s theory of gravitation to the solar system, and he developed a conceptual view of evolutionary change in the structure of the solar system. He also demonstrated the usefulness of probability for interpreting scientific data.
