R. J. Boscovich's work on probabilityArchive for History of Exact Sciences - Tập 9 - Trang 306-324 - 1973
O. B. Sheynin
A description of Boscovich's (1711–1787) method of adjusting arc measurements is presented and its further history, including the incorporation of his method in the theory of linear programming, is traced in §1. A special feature of this section is a description of a connection, discovered by C. G. J. Jacobi, between least squares and one of the previous methods of adjusting observations.

Peirce’s Dragon-Head Logic (R 501, 1901)Archive for History of Exact Sciences - Tập 76 - Trang 261-317 - 2022
Minghui Ma, Ahti-Veikko Pietarinen
Peirce wrote in late 1901 a text on formal logic using a special Dragon-Head and Dragon-Tail notation in order to express the relation of logical consequence and its properties. These texts have not been referred to in the literature before. We provide a complete reconstruction and transcription of these previously unpublished sets of manuscript sheets and analyse their main content. In the recons...... hiện toàn bộ
Blondel et les oscillations auto-entretenuesArchive for History of Exact Sciences - Tập 66 - Trang 485-530 - 2012
Jean-Marc Ginoux, René Lozi
En 1893, « physicien-ingénieur » André Blondel invente l’oscillographe bifilaire permettant de visualiser les tensions et courants variables. À l’aide de ce puissant moyen d’investigation, il entreprend tout d’abord l’étude des phénomènes de l’arc électrique alors utilisé pour l’éclairage côtier et urbain puis de l’arc chantant employé comme émetteur d’ondes radioélectriques en T.S.F. En 1905, il ...... hiện toàn bộ
