There is a term which I am confused with LT1028 is -1 stable while LT1128 is +1 stable. At first I thought that -1 stable means that the opamp is stable when we have negative feedback and +1 stable is positive feedback, but then I was told that it's wrong that if my gain is 2 or 50, then it's not...

In A Christmas Carol, Dickens describes a grocery shop: The Grocers’! oh, the Grocers’! nearly closed, with perhaps two shutters down, or one; but through those gaps such glimpses!

This is one of my main concerns. What did Buddha actually mean by 'kalpa'? I know Buddha said that the Earth will die by fire, and then all beings will be born in the Abhasara loka.
