'Neglecting' there means 'If one neglects' Rama not 'You neglected'

'Neglecting gravity...' means 'Gravity isn't important for this calculation' not 'Why are you neglecting gravity?'

It's a standard English construction with no emotional content to the word 'neglect' (which does have the alternate meaning 'Doesn't feed his kids') and let's leave it at that, on with the show thanks

'On with the show' there means 'Ignore me' btw
