My analogy probably isn’t perfect but isn’t this how an abacus or a slide rule works? You expend energy to set the values for computation but the act of computing and then reading them expends no energy.
- bgnn 2y agoYeah this is a good analogy
- heavenlyblue 2y agoThat's a bad analogy because moving stuff in abacus is the computation itself.
- lupusreal 2y agoSuppose you put the abacus sideways, such that setting a bead requires working against gravity, but then returning the bead to the original position gives you that energy back?
