He learned agriculture but was not successful at it.
Around 1831 he entered St Peter's College, Cambridge.
In 1827 he earned his BA in mathematics.
He received his MA in 1830.

The Cambridge Philosophical Society and the Geological Society of London published his papers on physical geology.
He wedded mathematics to geology and investigated the effects of force on geological formations.
Between 1838 and 1842 Hopkins presented papers to the Royal Society on the Earth's rotation, precession and nutation.
His observations led him to dispute the then accepted theory that the Earth had a largely liquid center.
In a British Association report in 1847 he explained earthquakes and volcanoes using his solid core model.
In honor of his scientific work he became a Fellow of the Royal Society in June of 1837, and earned the Geological Society of London Wollaston Medal in 1850.
