Kære IFA videnskabelige medarbejder. Jens Lindhard var professor i teoretisk fysik fra 1956 frem til sin pensionering i 1992, se evt. https://phys.au.dk/om-instituttet/historie/jens-lindhard-1922-1997. Han er en af instituttets mest markante skikkelser gennem tiden. Instituttet planlægger derfor at fejre 100-året for hans fødsel med et en-dags symposium. Det primære formål med arrangementet er at formidle historien om Jens Lindhard til vores medarbejdere og studerende. Jens blev født den 26. februar 1922. Symposiet var derfor oprindeligt planlagt til fredag 25/2 men blev udskudt til torsdag 15/9 pga. covid-19 situationen i begyndelsen af året. Datoen 15/9 markerer samtidigt et lille jubilæum, idet Jens' første artikel om retningseffekter blev offentliggjort netop 15/9, se vedhæftede. Formatet er en række foredrag ved internationale og lokale fysikere mfl. blandet med kortere indslag. Et foreløbigt program er vedhæftet. Instituttet og Lindhard legatet er vært under arrangementet, herunder ved frokosten, som serveres i instituttets kantine for foredragsholdere, medarbejdere, studerende og et mindre antal inviterede gæster. Vi håber, at du vil bakke op om arrangementet. Mere information følger ultimo august. Venlig hilsen, Allan og Ulrik Dear IFA scientific staff member. Jens Lindhard was a professor of theoretical physics from 1956 until his retirement in 1992, see e.g. https://phys.au.dk/om-instituttet/historie/jens-lindhard-1922-1997. He is historically one of the most prominent figures of the department. The department therefore plans to celebrate the 100th anniversary of his birth with a one-day symposium. The primary purpose of the event is to convey the story of Jens Lindhard to our staff and students. Jens was born on February 26, 1922. The symposium was therefore originally planned for Friday 25/2 but was postponed to Thursday 15/9 due to the covid-19 situation at the beginning of the year. The date 15/9 also marks a small anniversary, as Jens' first article on directional effects was published on 15/9, see the attached paper. The format is a series of lectures by international and local physicists etc., mixed with shorter features. A preliminary program is attached. The department and the Lindhard scholarship host the event, including lunch, which is served in the department's canteen for speakers, staff, students and a small number of invited guests. We hope to see you at the event. More information will follow at the end of August. Sincerely, Allan and Ulrik
