Temporal Anisotropy . In a short video clip showing two billiard balls bouncing off each other, forward and backward in time are indistinguishable if one ignores friction and inelasticity.  In a longer video of a billiards break, the future is the end in which the balls are no longer in a nicely ordered triangle. If causes can be attributed to effects as easily as effects can be attributed to causes, then causal laws do not distinguish past and future, and the future for an event is the direction of increasing disorder in the system.  Traces and memories of the past are a localized increase in order at the expense of an increase in system-wide disorder. Due to statistical considerations, some systems can cycle between order and disorder.  In such systems the direction locally considered to be future can vary over the timeline of the system.

Origin of Species - Henslow's Advice
If ever you find yourself sitting down to read Darwin's Origin of Species , keep in mind John Stevens Henslow's (1796-1861) advice to the young Charles Darwin. Henslow was one of Darwin's professors at Cambridge. In fact, it was Henslow who recommended Darwin to Captain Robert FitzRoy (1805-1865) of the HMS Beagle. Before Darwin set sail, Henslow recommended that he take Sir Charles Lyell's Principles of Geology . Lyell's book had a profound impact upon the young Charles and its influence is seen throughout Darwin's work. Henslow advised Darwin, "By all means read it for the facts, but on no account believe the wild theories." [2] We seek to pass this advice on to you. By all means read it for the facts, but on no account believe the wild theories.

Darwin’s theory challenged not only the prevailing view of the independent creation of species but also larger claims of religion and science. Darwin explicitly denied the validity of natural theology, which posited that species’ adaptations to their environments was proof of their “intelligent design” by a creator. It was natural selection, not independent creation, that resulted in these adaptations, Darwin argued. Moreover, Darwin’s use of scientific methodology to prove his theory amounted to an explicit critique of naturalists who would attempt to ignore the scientific validity of his theory because of its controversial nature. While the text of The Origin of Species did leave room for religious theology, Darwin’s overall commitment to scientific rationale rather than theological reasoning pitted him against religious doctrine. Darwin’s text was controversial when it was published, and it remains controversial today. However, his theory of natural selection has stood the test of time in scientific circles, and it remains the leading scientific explanation for the origin of species.

1876 During the summer begins to write an autobiographical memoir for his children and future grandchildren. ‘I know that it would have interested me greatly to have read even so short and dull a sketch of the mind of my grandfather written by himself, and what he thought and did, and how he worked.’ This memoir published in edited form in Francis Darwin’s Life and Letters of Charles Darwin (1887) Publishes The Effects of Cross and Self Fertilisation in the Vegetable Kingdom . In September Darwin’s first grandchild is born to Francis and Amy Darwin. Amy dies in childbirth and Francis goes to live with his parents at Down House with the baby, Bernard Darwin. Francis becomes Darwin’s secretary and botanical assistant.
