Dimitri Riabouchinsky (1882–1962) – Autograph - Lot 201
Dimitri Riabouchinsky (1882–1962) – Autograph
• Dimitri Riabouchinsky’s work journal for the year 1954. Personal notebook containing notes, 148 pp. (entirely filled in with pen and pencil), 32 x 24 cm (spiral-bound), binding as is, contents as is (stains and tears). The notebook contains 18 loose pages with mathematical formulas and calculations, in various formats.
The notebook contains a wide variety of daily notes: addresses and phone numbers, newspaper clippings, excerpts from articles, drawings and diagrams of device details, full pages and fragments of mathematical calculations and formulas, notes taken while preparing articles and books (chapters and sections), a fragment of an article on fluid mechanics with handwritten corrections, and drafts of letters.
This unique workbook accompanied the researcher Dimitri Riabouchinsky for an entire year; it reflects his daily work, the correction of articles and calculations, test calculations, and the verification of various ideas. Over the course of the year, the author continues or revisits calculations in hydrodynamics and theoretical physics, and performs a series of calculations on the topic of electromagnetic waves (using Maxwell’s equations). He performs calculations of wave equations and examines their solutions for electromagnetic and acoustic waves, using potential and vector analysis. Several calculations focus on the motion of an ideal fluid (using Euler’s equation), as well as on the vortex motion of fluids. An important document in the context of Dmitri Riabouchinsky’s fundamental research in the field of hydrodynamics and wave motion.

The notebook contains daily notes of a wide variety of nature: addresses and phone numbers, newspaper clippings, article excerpts, drawings and diagrams of device parts, full pages and fragments of mathematical calculations and formulas, notes from the preparation of articles and books (chapters and sections), a fragment of an article on fluid mechanics with handwritten corrections, and drafts of letters.
A unique workbook that accompanied researcher Dmitry Ryabushinsky for an entire year, reflecting his daily work, corrections to articles and calculations, test calculations, and the verification of various ideas. Throughout the year, the author continues or returns to calculations in hydrodynamics and theoretical physics, performing a series of calculations on electromagnetic waves (using Maxwell’s equations). He performs calculations of wave equations and examines their solutions for electromagnetic and acoustic waves using potential and vector analysis. A number of calculations examine the motion of an ideal fluid (using Euler’s equation), as well as the vortex motion of a fluid. This document is of great value in the context of Dmitry Ryabushinsky’s fundamental research in the field of hydrodynamics and wave motion.
