    2034 Bernoulli, provisional designation 1973 EE, is a stony asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 5 March 1973, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland.[6]

    The S-type asteroid orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,229 days). Its orbit has an eccentricity of 0.18 and an inclination of 9° with respect to the ecliptic.[1] The first used precovery was taken at Palomar Observatory in 1951, extending the asteroid's observation arc by 22 years prior to its discovery, while the first unused observation took place ten years earlier at Uccle Observatory in 1941.[6]

    A rotational light-curve of this asteroid was obtained from photometric observations by Michael Alkema at the U.S. Elephant Head Observatory (G35), Arizona, in December 2012. The light-curve gave a rotation period of 6.248±0.001 hours with a brightness amplitude of 0.21 in magnitude (U=2+).[5]

    According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 8.5 kilometers in diameter and its surface has an albedo of 0.17,[4] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 9.4 kilometers.[3]

    The minor planet was named in honour of the Bernoulli family, a dynasty of mathematicians from the city of Basel, Switzerland. In particular, Jacob Bernoulli (1654–1705), founder of the calculus of variations, Daniel Bernoulli (1700–1782), co-founder of hydrodynamics, and Johann Bernoulli (1667–1748), contributor to integral calculus and the teacher of Leonhard Euler, after whom the minor planet 2002 Euler is named. The lunar crater Bernoulli also honors the Swiss dynasty.[2] Naming citation was published on 1 June 1980 (M.P.C. 5359).[7]
