Everything in nature is the result of fixed laws.
Charles DarwinRead
When the sexes differ in beauty, in the power of singing, or in producing what I have called instrumental music, it is almost invariably the male which excels the female.
Interpretation
The quote highlights that in certain traits, such as beauty and musical ability, male members of a species often surpass females.
In this quote, Charles Darwin observes a trend found in various species where males tend to exhibit superior characteristics related to beauty, vocal ability, or instrumental talents compared to females. This phenomenon can be attributed to evolutionary processes, where males may display these traits to attract females or deter rivals, ultimately influencing mating success and species propagation.
In practice
In a lecture on evolutionary biology, this quote could illustrate the concept of sexual dimorphism.
Everything in nature is the result of fixed laws.
The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.
I am quite conscious that my speculations run beyond the bounds of true science....It is a mere rag of an hypothesis with as many flaw[s] & holes as sound parts.
We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.
I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.
we are always slow in admitting any great change of which we do not see the intermediate steps
The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
I have to keep going, as there are always people on my track. I have to publish my present work as rapidly as possible in order to keep in the race. The best sprinters in this road of investigation are Becquerel and the Curies.
If you aren't confused by quantum mechanics, you haven't really understood it.
A lot of the things you see in science fiction revolve around black holes because black holes are strong enough to rip the fabric of space and time.
I need scarcely say that the beginning and maintenance of life on earth is absolutely and infinitely beyond the range of all sound speculation in dynamical science. The only contribution of dynamics to theoretical biology is absolute negation of automatic commencement or automatic maintenance of life.
Astronomers can look back in time. We can look at things as they used to be. We have an idea there was a Big Bang explosion 13.7 billion years ago. We have a story of how galaxies and stars were made. It's an amazing story.
