Alma Johanna Ruubel

A Alma Johanna Ruubel (sẽn ki yʋʋmd 1899 sigr kiuug rasem 28 n ki yʋʋmd 1990 yʋʋm-vẽkr kiuug rasem 21) yaa Ɛstõni bãngd la karen-saamb sẽn da tʋmd n na n paas b sẽn boond t'a curvilinear geometry wã.

 A vɩɩmã la a tʋʋma 
A Alma Johanna Ruubel roga Õisu Parish (sẽn yaa Viljandi Parish rũndã-rũndã), Viljandi County, la a bɩɩ Peebu pʋʋgẽ sẽn be Ōisu munisipal Viljandimaa. A ba a Juhan Ruubel ra yaa tãn-metre, la a ma a Ann (a sẽn boond t'a Mankin) ra yaa roog pʋg-sadba.

Yʋʋmd 1909 wã, a kẽe Peebu lekollã sẽn yaa Risi buud-gomd sẽn tar karen-biis a tãabo, Õisu Parish pʋgẽ, la yʋʋmd 1912 wã, a kẽe Viljandi Estoni Edukasiõ Sosiete wã karen-bi-pugli lekoll sẽn yaa Estoni buud-gomd pʋgẽ, t'a paam a diplome wã yʋʋmd 1916. A kell n kẽnga Viljandi pagbã lekoll sẽn be Risi wã, tɩ b lebg lekoll sẽn tar karen-biis a yopoe pipi dũni gill zabrã wakat la Alemayn sodaasã sẽn wa n so-b yʋʋmd 1918 wã. Sẽn na yɩl n kẽng taoor ne a karengã, a Ruubel ne kom-pugli a taab naaga taab n sigl karen-biis sull a nii soabã, tɩ karen-saam dãmb toor-toorã bool-ba.

A kẽnga Tartu inivɛrsite wã yʋʋmd 1926. A sɩng n da paamda ligdi, a sẽn da kõt lekoll-dãmbã, la yʋʋmd 1929 wã, a Gerhard Rägo sẽn yaa porfesɛɛrã bool-a lame t'a na n wa lebg matematikã lekollã sõngda, baa ne a sẽn da yaa yʋʋm a tãab-n-soabã karen-biiga. Rẽ kɩtame t'a Ruubel lebg pipi pag sẽn zãms matematikã Tartu Inivɛrsite wã. Yʋʋmd 1932, a paama a karengã ne pẽgre.

Yʋʋmd 1935 wã, a ra rat n sɩngame n na n maan vaeesg sẽn tɩ loe ne sõor la grafikã.

A Rägo tagsame t'a vaeesgã sẽn sa wã zemsame tɩ b kõ-a t'a yɩ a karen-saambã tʋʋmd sebre. A Ruubel paama a karen-saambã magzɛmd matematikã wɛɛngẽ yʋʋmd 1936. A goma a tʋʋm-noor ning sẽn boond tɩ "The JC Adams Method for the Numerical Integration of Ordinary Differential Equations" n paam a Ph.D. yʋʋm 1946.

 Karen-saamba 
A Ruubel sẽn paam a karengã poore, a kell n tʋma be, pipi a yɩɩ karen-saamb kãsma, n yaool n lebg karen-saamb sẽn be sull a ye pʋgẽ (b sẽn yãk-a t'a yɩ karen-saamb yʋʋmd 1949).
