In general binomial nomenclature (the names of species) and other scientific terms will be presented in Latin. For example, the scientific name of a dog is a canis lupus familiarus. However, even though Latin is used in this way, no one really speaks Latin anymore! So naming Latin the language of science seems rather silly.
When it comes down to it, there is no doubt that English is the language of science. Michael Gordin, a professor at Princeton for the history of modern sciences, says this: “If you looked around the world in 1900, and someone told you, ‘Guess what the universal language of science will be in the year 2000?’ You would first of all laugh at them because it was evident that no one language would be the language of science, but a mixture of French, German and English would be the right answer.”
He goes on to explain that English did not necessarily become the language of science due to efficiency. Or some increase of use among the scientific community, but because in the 1900s German collapsed as the language of science due to historical events.
Furthermore, the United States became a powerhouse of efficiency. Adopted seemingly isolationist policies causing foreign language exposure to drop exponentially in the scientific community.
With that in mind, there are many people across the world that are learning English as a second language because of their ambitions to become a scientist or an engineer.
