<< The most celebrated part of this account, however, is at 2.216–93, where Lucretius [Titus Lucretius Carus] maintains that not only to explain how atomic collisions can occur in the first place, but also to account for the evident fact of free will in the animal kingdom, it is necessary to postulate a minimal indeterminacy in the motions of atoms, an unpredictable ‘swerve’ (clinamen) ‘at no fixed place or time’. Otherwise we would all be automata, our motions determined by infinitely extended and unbreakable causal chains >>

AA << consider a specific kind of negative feedback, which makes bursts smaller in the excess of protein >>
<< Increasing the strength of the feedback may lead to dramatically different outcomes depending on a key parameter, the noise load >>
<< for noise loads smaller than critical, the coefficient of variation remains bounded with increasing feedback strength; contrastingly, if the noise load is larger than critical, the coefficient of variation diverges to infinity in the limit of ever greater feedback strengths >>
<< Interestingly, high-cooperativity feedbacks have lower critical noise loads, implying that low-cooperativity feedbacks in burst size can be preferable for noisy proteins >>
