The atom consists of a nucleus and electrons. This is a very crude picture, but it is the one we have to work with.

More from Erwin Schrodinger
"We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators. The reason why we believe that we are in it, that we belong to the pic…"
"The greatest American art form is the comic strip."
"What we observe as material bodies and forces are nothing but shapes and variations in the structure of space. Particles are just schaumkommen (appearances)!"
"If you are hungry, you can eat a carrot. If you are thirsty, you can drink water. If you are cold, you can put on a coat. But what do you do if you are lonely?"
"The most important thing is not to stop questioning. Curiosity has its own reason for existence."
About Erwin Schrodinger (1887-1961)
Austrian physicist who shared the 1933 Nobel for the wave equation that bears his name and the famous cat thought-experiment. Closely associated with Werner Heisenberg (matrix-mechanics rival who reached the same physics by different math) and Albert Einstein (his pen-pal on quantum interpretation). For an intellectual contrast, see Niels Bohr, Danish physicist and architect of the Copenhagen interpretation — Schrödinger's cat thought-experiment was specifically designed to ridicule Bohr's 'observer-dependent reality' reading of quantum mechanics — Schrödinger thought the Copenhagen interpretation was absurd; the cat was meant as reductio ad absurdum.

Understanding this quote
What it means
The atomic model we use is a simplified approximation of reality, not a complete truth. Scientists must accept working with imperfect mental models because that is the best available framework. Acknowledging a model's limitations is intellectually honest, not defeatist — it keeps the door open for refinement while still allowing practical progress in understanding nature.
Relevance to Erwin Schrodinger
Schrödinger developed wave mechanics in 1926, replacing Bohr's crude planetary atom with a probabilistic wave function. He knew better than anyone that even his own equations were mathematical abstractions. His 'What is Life?' shows his habit of working confidently within acknowledged limitations — he built quantum biology from incomplete physics.
The era
In the 1920s–30s, atomic theory was rapidly overturning classical physics. Bohr's model had just been superseded by quantum mechanics, yet textbooks still taught the nucleus-plus-electrons picture. Scientists faced tension between useful simplifications and deeper truths — a defining intellectual challenge of the quantum revolution era.
