▁text book ▁was ▁published ▁in ▁ 1 9 4 9 . ▁It ▁was ▁subsequently ▁re vised ▁( also ▁called ▁At mos pher ic ▁Electric ity ▁but ▁with ▁a ▁new ▁publish er ) ▁in ▁ 1 9 5 7 , ▁with ▁the ▁second ▁edition ▁published ▁post hum ously ▁in ▁ 1 9 6 7 . ▁Chal mers ▁worked ▁across ▁the ▁whole ▁subject ▁of ▁atmos pher ic ▁electric ity , ▁but ▁he ▁published ▁most ▁papers ▁on ▁point ▁dis charge ▁( now ▁more ▁commonly ▁referred ▁to ▁as ▁cor ona ▁dis charge ) ▁and ▁the ▁charge ▁on ▁precip itation . ▁He ▁was ▁equally ▁at ▁home ▁with ▁theory ▁and ▁experimental ▁work , ▁including ▁developing ▁instrument ation ▁where ▁needed . ▁This ▁approach ▁reflected ▁his ▁rig orous ▁and ▁broad ▁training ▁in ▁experimental ▁physics ▁typical ▁of ▁the ▁Cav end ish ▁Labor atory ▁led ▁by ▁Thom son ▁and ▁R uther ford . ▁Many ▁of ▁his ▁field ▁experiments ▁were ▁carried ▁out ▁in ▁the ▁grounds ▁of ▁Dur ham ▁University ▁Observ atory . ▁ ▁Chal mers ▁was ▁also ▁a ▁respect ed ▁teacher ▁and ▁administrator ▁at ▁the ▁University ▁of ▁Dur ham ▁and ▁became ▁Dean ▁of ▁the ▁Science ▁Fac ulty ▁in ▁the ▁ 1 9 6 0 s . ▁The ▁J . A . ▁Chal mers ▁Prize ▁for ▁Ex perimental ▁Physics ▁is ▁still ▁awarded ▁to ▁the ▁best ▁under grad uate ▁student ▁of ▁experimental ▁physics . ▁A ▁Chal mers ▁prize , ▁created ▁in ▁ 1 9 6 8 , ▁is ▁also ▁given ▁to ▁the ▁best ▁student ▁taking ▁Physics ▁A - level ▁at ▁High gate ▁School . ▁ ▁Scient
