When it comes to Beatles references, scientists can't let it be

Scientists have a whimsical streak, as reflected in their research papers often referencing popular culture, including song lyrics. Among all musical acts, The Beatles emerge as the most frequently cited, according to a recent study published in the journal PLoS ONE. Co-author Gabriel Budel of Delft University of Technology remarked, "Some of these are genuinely brilliant."

The researchers found over 3,000 references to The Beatles in their papers, leading to creative substitutions. For instance, "The lung and winding road" was a reference to a Long COVID study, while "Here comes the SU(N)" transformed into a quantum computing paper about mathematical groups. Co-author Budel added, "Someone was having a very good day at their desk."

Back in 2014, Swedish scientists at the Karolinska Institute took the practice a step further by inserting Bob Dylan lyrics into their papers, starting with a 1997 Nature review titled "Nitric Oxide and inflammation: The answer is blowing in the wind." This led to a 2015 study on the prevalence of Dylan references in biomedical literature, with "The Times They Are A Changin'" and "Blowing in the Wind" topping the charts.
