modifyeNicolson te fèt Phyllis Lockett nan Macclesfield e li te ale nan Stockport High School pou fi.[1] Li te gradye nan Inivèsite Manchester ak yon B.Sc. an 1938, M.Sc. an 1939 ak yon doktora sou Twa Pwoblèm nan Fizik Teyorik an 1946.[1] Tèz doktora li te kòmanse ak rechèch sou [[reyon kosmik] ki te fèt anba sipèvizyon Lajos Jánossy an 1939 ak 1940.[2]
Analizè diferansyèl Hartree
modifyeDoktora Nicolson te dwe soumèt an 1941, men yo te entèwonp pa travay pandan lagè ak gwoup rechèch Douglas Hartree nan Inivèsite Manchester ant 1940 ak 1945. Pandan tan sa a, Nicholson te vin konpetan nan yon analis dijital ak itilizatè ekspè nan analizè diferansyèl Hartree a.[3] Nicolson, ansanm ak lòt manm gwoup rechèch la, te travay sou pwoblèm ki gen rapò ak defans pou Sant rechèch ak Developman Defans ayeryèn (pita Sant rechèch ak Developman rada), toulede fè pati Ministè Zam. De gwo kò rechèch Nicolson nan tan lagè, "konpòtman pasajè nan manyetwon sèl-anod la" ak "kondiksyon tèmik", te fòme baz pati II ak II nan tèz doktora 1946 li a, Twa pwoblèm nan fizik teyorik.[2]
Rechèch Nicolson sou kondiksyon chalè ki gen rapò ak solisyon ekwasyon chalè a, ak kòlèg li John Crank li te envestige estabilite nimerik plizyè solisyon teknik. Algorit yo konnen kounye a kòm Metòd Crank-Nicolson te soti nan travay sa a e li te pibliye an 1947.[4]
Lavi ak travay apre lagè
modifyeNicolson te yon etidyan rechèch nan Cambridge depi 1945 e li te konplete tèz doktora li nan Inivèsite Victoria Manchester (kounye a Inivèsite Manchester) an 1946.[2] Li te Tucker-Price Research Fellow nan Girton College, Cambridge soti 1946 rive 1949, li te travay nan Laboratwa Cavendish.[1],[5] Nicolson te deplase nan Leeds alantou janvye 1950 ak mari li Malcolm Nicolson, tou yon fizisyen, paske li te nonmen pwofesè nan fizik nan Inivèsite Leeds.[6],[5] Phyllis Nicholson te marye ak Malcolm an 1942 e yo te gen de (2) pitit gason, Donald Macleod Nicolson (fèt 20 septanm 1947 nan Cambridge) ak Roderick Ian Nicolson (fèt 5 fevriye 1950 nan Leeds).
Nan laj 33 zan Malcolm Nicolson te mouri nan yon aksidan tren nan mwa desanm 1951, epi Phyllis te rekòmanse travay kòm pwofesè.[7],[6] An 1955, Nicolson te marye ak fizisyen Malcolm McCaig, ki te gen yon pitit gason Ian McCaig (fèt fevriye 1946) ki soti nan yon maryaj anvan.[6],[5] Nan mwa me 1957, Nicolson ak McCaig te gen yon pitit gason ansanm, Andrew Malcolm McCaig.[5] Twa (3) pitit gason Nicolson yo te fini fè yon doktora nan matematik,[5] sikoloji,[8] ak jeyoloji.[9]
Nicolson te mouri nan kansè nan tòs an 1968 nan Sheffield.[6]
