<p>Impor teks terkontrol dari Wikipedia bahasa Indonesia; revisi 27712856; atribusi sumber disertakan.</p> <p><b>Halaman baru</b></p><div>&#039;&#039;&#039;Ernest William Brown&#039;&#039;&#039; (29 November 1866 – 22 Juli 1938) adalah seorang [[matematikawan]] dan [[astronom]] kelahiran Inggris yang dikenal atas karyanya dalam bidang [[mekanika langit]], khususnya dalam pengembangan teori matematis tentang gerak [[Bulan]]. Karyanya menjadi dasar penting dalam perhitungan efemeris bulan modern.<br /> <br /> == Pendidikan dan awal karier ==<br /> Brown lahir di [[Hull]], Inggris, dan menempuh pendidikan di [[Christ&#039;s College, Cambridge]]. Ia merupakan murid dari matematikawan terkenal [[George H. Darwin]], yang kemudian memengaruhi minatnya dalam studi gerak bulan dan pasang surut.<br /> <br /> == Kontribusi ilmiah ==<br /> Brown dikenal terutama karena revisi besar terhadap teori bulan yang sebelumnya dikembangkan oleh [[Peter Andreas Hansen]]. Ia menerbitkan hasil kerjanya dalam beberapa volume, yang berpuncak pada karya monumentalnya:<br /> * &#039;&#039;Lunar Theory: A Summary of the Theory of the Motion of the Moon&#039;&#039; (1919).<br /> <br /> Metode yang dikembangkan Brown menggunakan deret [[Fourier]] dan pendekatan [[perturbasi]] untuk memodelkan pengaruh gaya gravitasi Matahari dan planet-planet lain terhadap orbit bulan. Teorinya digunakan dalam pembuatan efemeris astronomi resmi selama beberapa dekade.<br /> <br /> == Karier di Amerika Serikat ==<br /> Pada tahun 1891, Brown pindah ke [[Amerika Serikat]] dan menjadi profesor matematika di [[Haverford College]], sebelum akhirnya mengajar di [[Yale University]], tempat ia menghabiskan sebagian besar karier akademiknya.<br /> <br /> == Pengakuan dan penghargaan ==<br /> Brown menjadi anggota [[Royal Society]] pada tahun 1896. Ia menerima sejumlah penghargaan bergengsi, termasuk:<br /> * [[Gold Medal of the Royal Astronomical Society]] (1907)<br /> * [[James Craig Watson Medal]] dari [[National Academy of Sciences]] (1936)<br /> <br /> == Kematian ==<br /> Ernest W. Brown meninggal dunia di [[New Haven, Connecticut]] pada 22 Juli 1938 dalam usia 71 tahun. Meskipun kemudian digantikan oleh metode numerik dan komputasi modern, teori bulan ciptaannya tetap menjadi tonggak utama dalam sejarah [[astronomi teoretis]].<br /> <br /> == Lihat pula ==<br /> * [[Teori bulan]]<br /> * [[Mekanika langit]]<br /> * [[Efemeris]]<br /> * [[George H.
