Everything in nature is the result of fixed laws.
Charles DarwinRead
This preservation of favourable variations and the destruction of injurious variations, I call Natural Selection, or the Survival of the Fittest. Variations neither useful nor injurious would not be affected by natural selection and would be left a fluctuating element.
Interpretation
Natural selection emphasizes that beneficial traits are preserved while harmful traits are eliminated in evolution.
This quote by Charles Darwin explains the mechanism of natural selection, where traits that confer a survival advantage are retained and passed on to future generations, while detrimental traits are eliminated. This process leads to the evolution of species, as variations that are neither beneficial nor harmful remain unchanged. It highlights how nature selectively favors specific characteristics, which is central to the theory of evolution.
In practice
In a biology class discussing the principles of evolution.
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
When we benefit from CT scanners, M.R.I. devices, pacemakers and arterial stents, we can immediately appreciate how science affects the quality of our lives.
Economics is in many respects the queen of the soft sciences. It's expected to be better than the rest. It's my view that economics is better at the multi-disciplinary stuff than the rest of the soft science. And it's also my view that it's still lousy.
In fourth grade, I was interested in all areas of science. I particularly loved learning about how the earth was created.
As long as our brain is a mystery, the universe, the reflection of the structure of the brain will also be a mystery.
It is possible in medicine, even when you intend to do good, to do harm instead. That is why science thrives on actively encouraging criticism rather than stifling it.
The more one chases the quanta, the better they hide themselves.
