Bodies do not produce sensations, but complexes of elements (complexes of sensations) make up bodies.
Ernst MachRead
It would not become physical science to see in its self created, changeable, economical tools, molecules and atoms, realities behind phenomena... The atom must remain a tool for representing phenomena.
Interpretation
The quote emphasizes that atoms and molecules are merely concepts used to understand phenomena rather than ultimate realities.
Ernst Mach highlights the philosophical perspective that the tools of science, such as atoms and molecules, are constructs that help us interpret the observable world. He argues that these concepts should not be confused with the deeper realities they aim to represent, suggesting that scientific tools are fundamentally changeable and serve as frameworks for understanding phenomena rather than definitive truths.
In practice
Discussing the nature of scientific theories in a classroom setting.
Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.
The first footfalls on Mars will mark a historic milestone, an enterprise that requires human tenacity matched with technology to anchor ourselves on another world.
If a given scientist had not made a given discovery, someone else would have done so a little later. Johann Mendel dies unknown after having discovered the laws of heredity: thirty-five years later, three men rediscover them. But the book that is not written will never be written. The premature death of a great scientist delays humanity; that of a great writer deprives it.
The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.
With its billions of interconnected neurons, whose interactions change from millisecond to millisecond, the human brain is an archetypal complex system.
So if the worth of the arts were measured by the matter with which they deal, this art-which some call astronomy, others astrology, and many of the ancients the consummation of mathematics-would be by far the most outstanding. This art which is as it were the head of all the liberal arts and the one most worthy of a free man leans upon nearly all the other branches of mathe matics. Arithmetic, geometry, optics, geodesy, mechanics, and whatever others, all offer themselves in its service.
