Oparin Bubble Theory Definition

The Russian scientist Alexander Oparin was one of the greatest biochemists of the 20th Century. He was a prominent leader in evolution theory and created the primordial soup theory which posits that life originated from carbon-based molecules.

Oparin was a renowned enzymologist with significant contributions; notable among these was his groundbreaking work in industrial biochemistry in the USSR. His mastery of the sciences won made him many awards, including the highest order of the Soviet Union.

A Little More on What is Oparin Bubble Theory

Also called The Darwin of the 20th Century, Alexander was born in the city of Uglich in Russia on the 2nd of March 1894. At a tender age of nine, his parents left their village which had no secondary school and moved to Moscow to allow him to continue his studies.

Alexander attended the Moscow State University where he met a fellow Russian Plant Physiologist named K. A. Timiryazev whose research was influenced by Charles Darwin. By 1917, he graduated from the university and a decade after, became a full professor of biochemistry.

At a 1922 gathering of the Russian Botanical Society, Oparin proposed a hypothesis that life on Earth was a gradual evolution of carbon-based molecules through a primordial soup. However, he was not the only scientist at the time with such thoughts as a British Biologist called J. B. S. Haldane also held a similar belief.

In the year 1924, he officially introduced his theory of primordial soup through which life evolved. The theory asserts thus:

  • The characteristics and manifestations of life results from the evolution process of matter. This implies that there is no fundamental difference between living and lifeless matter.
  • At inception, the earth had a reducing atmosphere comprising materials such as ammonia, methane, hydrogen and water vapor which played a vital role in the evolution of life.
  • An increase in the complexity of molecules because of constant reactions created new properties. The mutual relationship and spatial arrangement of the molecules established a new colloidal-chemical order for simpler organic chemical relations.
  • The characteristics of living organisms depended on factors such as competition, struggle for existence, and natural selection.
  • The Second Law of Thermodynamics does not apply to living matter because they are open systems that exchange materials and energy with their external environment.

Oparin held firmly and proved to the world that organic chemicals resulted in microscopic localized systems from a solution of organic substances. To him, this is where living things emanated from. He also provided more clarity on Charles Darwin’s theory of evolution.

He argued that life was formed by chance through the accumulation of simple organic and inorganic materials. These materials developed into a complex compound which later formed primordial organisms.

This assertion was initially challenged but later accepted and adopted by the scientific society at the time as the basis for any proposed hypothesis. By 1935, Oparin achieved the greatest landmark of his academic career by helping to establish the A.N. Bakh Institute of Biochemistry, a part of the USSR Academy of Sciences.

Oparin published his seminal work, The Origin of Life in 1936. He became a corresponding member of the USSR Academy of Sciences in 1939 and a full member in 1946. He later rose to the position of director in 1946 at the Institute of Biochemistry.

He supported the works of Trofim Lysenko and Olga Lepeshinskaya in the 1940s and 1950s although Oparin knew these theories won’t pass rigorous scientific examination. To many observers, his support for the scientists was to please the communist party and further his career.

In 1957, he organized the first international meeting in Moscow on the origin of life. He also coordinated the hosting of two successive meetings in 1963 and 1970.

Oparin was a 1969 nominee for the Hero of Socialist Labor and became the president of the International Society for the Study of the Origin of life the following year.

He was a recipient of the Lenin Prize in 1974, and the Lomonosov Gold Medal in 1979 for his contributions to the field of biochemistry. Oparin also received the five Orders of Lenin, the most prestigious national decoration of the Soviet Union.

Three-dimensional bubbles in Rayleigh–Taylor instability, Oparin, A., & Abarzhi, S. (1999). Physics of Fluids, 11(11), 3306-3311. The study investigated the nonlinear stages of Rayleigh–Taylor instability (RTI) for three-dimensional flow. The study shows that numeral and analytical approaches offer the best results.

A new type of the evolution of the bubble front in the Richtmyer–Meshkov instability, Abarzhi, S. I. (2002). Physics Letters A, 294(2), 95-100. This study examines the coherent motion of bubbles and spikes in the Richtmyer–Meshkov instability. The research shows the interplay of harmonics in the nonlinear dynamics, leading to a new prediction of the bubble front evolution.

Review of nonlinear dynamics of the unstable fluid interface: conservation laws and group theory, Abarzhi, S. I. (2008). Physica Scripta, 2008(T132), 014012. This paper looked at theoretical and empirical modeling approaches of the nonlinear Rayleigh-Taylor instabilities in the last few years. The study summaries the results of the group theory analysis and created a set of experimental and numerical data sets.

Three-dimensional array structures associated with Richtmyer-Meshkov and Rayleigh-Taylor instability, Inogamov, N. A., & Oparin, A. M. (1999). Journal of experimental and theoretical physics, 89(3), 481-499. This study was conducted on the premise that dynamic systems pass through a transition during development from an initial, weakly disturbed state to a limiting or asymptotic stationary state. The research shows that stationary states are stable toward large-scale disturbances in Richtmyer-Meshkov and Rayleigh-Taylor instability. Furthermore, both arrays are complementary, and at the point of inversion, jets of triangular arrays surfaced through the bubbles of the hexagonal array.

Bubble velocity in the nonlinear Rayleigh–Taylor instability at a deflagration front, Modestov, M., Bychkov, V., Betti, R., & Eriksson, L. E. (2008). Physics of Plasmas, 15(4), 042703. This study used extensive direct numerical simulations to systematically study Rayleigh–Taylor instability at a deflagration front. The researchers found that the larger the gravitational field, the more the effects of bubble rising which later dominate the deflagration dynamics. The study also put forth that intrinsic properties of the deflagration front are crucial when there is low or no gravitational field. In this scenario, the velocity of a planar front determines the deflagration, which is numerically sound and correct where a wide range of Froude numbers is being used.

Low-symmetric bubbles in Rayleigh–Taylor instability, Abarzhi, S. I. (2001). Physics of Fluids, 13(8), 2182-2189. The study analyzed the 3D-2D dimensional crossover for a nonlinear structure occurring in the Rayleigh–Taylor instability (RTI). The resultant flow with low rectangular symmetry was found to be anisotropic in the plan. 3D bubbles present in RTI retained a close-circular contour, and this made continual 2D conversion almost impossible.
