Leonhard Euler (1707 – 1783)
From `A Short Account of the History of Mathematics’ (4th edition, 1908) by W. W. Rouse Ball.
Leonhard Euler was born at Bâle on April 15, 1707, and died at St. Petersburg on September 7, 1783. he was the son of a Lutheran minister who had settled at Bâle, and was educated in his native town under the direction of John Bernoulli, with whose sons Daniel and Nicholas he formed a lifelong friendship. When, in 1725, the younger Bernoullis went to Russia, on the invitation of the empress, they procured a place there for Euler, which in 1733 he exchanged for the chair of mathematics, then vacated by Daniel Bernoulli. The severity of the climate affected his eyesight, and in 1735 he lost the use of one eye completely. In 1741 he moved to Berlin at the request, or rather command, of Frederick the Great; here he stayed till 1766, when he returned to Russia, and was succeeded at Berlin by Lagrange. Within two or three years of his going back to St. Petersburg he became blind; but in spite of this, and although his house, together with many of his papers, were burnt in 1771, he recast and improved most of his earlier works. He died of apoplexy in 1783. He was married twice.
I think we may sum up Euler’s work by saying that he created a good deal of analysis, and revised almost all the branches of pure mathematics which were then known, filling up the details, adding proofs, and arranging the whole in a consistent form. Such work is very important, and it is fortunate for science when it fall into hands as competent as those of Euler.

Tanya pada diri sendiri
Aku bertanya pada diriku sendiri, aku merenungi apa yang pernah ku alami. Aku pengen
ini pengen itu tapi itu hanyalah mimpi. Mungkin orang laen menilaiku, hidupku
enak, aku bisa tersenyum, bercanda bersuka ria, tapi sesungguhnya yangku alami
belum tentu seperti itu. Aku pernah menangis merenungi nasibku yang seperti
ini. Aku sadar bahwa dalam diriku banyak kekurangan, tapi aku tidak tau
bagaimana mengatasi kekurangan tersebut, itulah yang menjadi masalah buatku.
Apa yang kurencanakan sebagiqn besar tidak terlaksana dan apa yang tidak
kurencanakan justru terlaksana. Kenapa hal ini terjadi?? Aku sendiri masih
bingung mencari jawabannya. Aku hanya bisa berusaha & berdoa.
Aku bertanya pada
diriku sendiri.
Kalau orang lain bisa kenapa aku tidak bisa?.
Kalau orang lain mampu kenapa aku tidak mampu?
Kalau orang lain bahagia kenapa aku tidak bahagia?
Meskipun jawaban itu tidak kutulis, mungkin jawaban dari
pertanyaan itu akan membuatku menjadi
lebih baik dari sekarang.
Aku hanya ingin hidup bahagia di dunia & akherat. Aku
sadar bahwa untuk mewujudkan hal tersebut perlu suatu proses dan untuk menuju
kesana tidaklah mudah. Aku ingin berusaha menyeimbangkan antara kebutuhan dunia
& akherat, tapi hal itu susah. Terkadang aku mementingkan dunia saja, aku
tidak peduli akherat.
Saat- saat tertentu aku pernah merasa bosan, males, sunyi,
sepi. Lalu aku bertanya pada diriku lagi.
Kenapa aku merasa bosan?
Kenapa aku merasa males?
Kenapa aku merasa kesepian?
Jawabannya tidak kutulis, tapi cukup kujawab dalam hati untuk
direnungi.
Semoga renungan ini bermanfaat bagi pembaca.
