17 July - Pierre Louis Moreau de Maupertuis born in 1698

Pierre Louis Moreau de Maupertuis (17 July 1698 – 27 July 1759)was a French mathematician, philosopher and man of letters. He became the Director of the Académie des Sciences, and the first President of the Prussian Academy of Science, at the invitation of Frederick the Great.

Maupertuis made an expedition to Lapland to determine the shape of the Earth. He is often credited with having invented the principle of least action; a version is known as Maupertuis's principle – an integral equation that determines the path followed by a physical system. His work in natural history is interesting in relation to modern science, since he touched on aspects of heredity and the struggle for life.

Guru Arjan (15 April 1563 – 30 May 1606)was the first of the two Gurus martyred in the Sikh faith and the fifth of the ten total Sikh Gurus. He compiled the first official edition of the Sikh scripture called the Adi Granth, which later expanded into the Guru Granth Sahib.

He was born in Goindval, in the Punjab, the youngest son of Bhai Jetha, who later became Guru Ram Das, and Mata Bhani, the daughter of Guru Amar Das.He completed the construction of Darbar Sahib at Amritsar, after the fourth Sikh Guru founded the town and built a pool.Guru Arjan compiled the hymns of previous Gurus and of other saints into Adi Granth, the first edition of the Sikh scripture, and installed it in the Harimandir Sahib.

Guru Arjan reorganized the Masands system initiated by Guru Ram Das, by suggesting that the Sikhs donate, if possible, one-tenth of their income, goods or service to the Sikh organization (dasvand). The Masand not only collected these funds but also taught tenets of Sikhism and settled civil disputes in their region. The dasvand financed the building of gurdwaras and langars (shared communal kitchens).

Guru Arjan was arrested under the orders of the Mughal Emperor Jahangir and asked by him to remove all references to Hinduism and Islam in his book. He refused, was tortured and executed in 1606 CE. Historical records and the Sikh tradition are unclear whether Guru Arjan was executed by drowning or died during torture.His martyrdom is considered a watershed event in the history of Sikhism.It is remembered as Shaheedi Divas of Guru Arjan in May or June according to the Nanakshahi calendar released by the Shiromani Gurdwara Parbandhak Committee in 2003.
