Hace 3 días · George Biddell Airy, Astronomer Royal at Greenwich Observatory, published in 1840 a paper on the dynamics of governors for astronomical telescopes. In it, he studied the dynamics of several kinds of governors and showed how the motion of them could be described using differential equations based on the pendulum model (1840 and 1851).
Hace 5 días · Thomson's innovations involved much detailed work to develop principles identified by George Biddell Airy and others, but contributed little in terms of novel physical thinking. Thomson's energetic lobbying and networking proved effective in gaining acceptance of his instrument by The Admiralty .
Hace 5 días · Foi estabelecido por Sir George Biddell Airy em 1851 (Wikipédia)" tornou-se referência para as longitudes no globo terrestre. Ele destaca que o meridiano, localizado no Observatório Real de Greenwich, em Londres, foi institucionalizado como o principal referencial, refletindo o poder da Inglaterra na época.
Hace 5 días · It was one of five 1874 transit expeditions organized by George Biddell Airy, Astronomer Royal at the Royal Observatory, Greenwich. The purpose of the expedition was to obtain an accurate estimate of the astronomical unit (AU), the distance from the Earth to the Sun, by measuring solar parallax.
Hace 4 días · His work was so detailed and convincing that when George Biddell Airy read it he commented, "It is one of the most remarkable applications of mathematics to physics that I have ever seen." It was considered the final word on the issue until direct observations by the Voyager flybys of the 1980s confirmed Maxwell's prediction that the rings were composed of particles.
Hace 6 días · Darin bestätigte er einen schon von George Biddell Airy (1837) auf anderem Wege gefundenen Wert, der die bis dahin publizierten erheblich verbesserte und dem heutigen sehr nahe kommt. Im Mai 1832 beobachtete Bessel den Merkurdurchgang vor der Sonne.
Hace 6 días · The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
