Atoms Quote by Arthur Compton
“The story is told of Lord Kelvin, a famous Scotch physicist of the last century, that after he had given a lecture on atoms and molecules, one of his students came to him with the question, "Professor, what is your idea of the structure of the atom." "What," said Kelvin, "The structure of the atom? Why, don't you know, the very word 'atom' means the thing that can't be cut. How then can it have a structure?" "That," remarked the facetious young man, "shows the disadvantage of knowing Greek."”

Source Anecdote: Lecture on atoms, attributed to Lord Kelvin, early 20th century physics discussions
Kelvin highlights that the term 'atom' literally means indivisible, questioning how a structure can exist for something defined as uncuttable.
In simple terms: The word 'atom' means uncuttable, so its structure seems contradictory.

The anecdote may oversimplify Kelvin's view and ignore modern atomic models.
![“[John] Dalton was a man of regular habits. For fifty-seven years he walked out of Manchester every day; he measured the rainfall, the temperature-a singularly monotonous enterprise in this climate. Of all that mass of data, nothing whatever came.

![“[Decoding the human genome sequence] is the most significant undertaking that we have mounted so far in an organized way in all of science.
