Talk:Magnus expansion

"Magnus appreciated that"
Yes, the dictionary gave you appreciate for whatever this was in the original language, but in this context it is better to use saw understand remarked etc. Appreciate can sometimes mean understand but not here, not in this sense. 2A01:CB0C:CD:D800:60FE:A4E2:BB36:340C (talk) 11:39, 3 April 2021 (UTC)

Similarly "at variance with other conventional perturbation theories" is an odd and unidiomatic use of that phrase; possible here is for instance by contrast. 2A01:CB0C:CD:D800:60FE:A4E2:BB36:340C (talk) 11:41, 3 April 2021 (UTC)
