Attractive force Non-cohesion limits

Boscovich: The area P (delimited by the curve and abscissa) represents the increase or decrease of the square of velocity" Δ(v2) of the particles... If the areas delimited by repulsive arches are less than the attractive areas, the particles will reach the first limit of cohesion (E) by: - a speed proportional to the surface delimited by the first attractive arch (EG), - moving on a circle having radius of AE and - continuously oscillating around that limit.

Boscovich: As a passes from one to the other limits of cohesion (or orbitals), a particle will lose or gain exactly a certain amount of Δv2, i.e. energy. That "quantum energy", as it is now called, between the two limits of cohesion is equal to the difference between areas delimited by repulsive and attractive arches. What physicists say is false: Max Planck “discovered” quantum theory at the end of 19. c. True: Boscovich’s theory is the very first quantum theory presented in 18. c.

Model of atoms J. J. Thomson (Cavendish Laboratory, Cambridge): (”The Corpuscular Theory of Matter”, Constable, London, 1907)

1. “Plum-pudding” model (Thomson) Positive charge (“pudding”)

Electrons (”plums”)

Model of atoms 2. Planetary model (Thomson)

Force and orbitals

“Suppose we regard the charged ion as Boscovichian atom exerting a central force on corpuscle which changes from repulsion to attraction and from attraction to repulsion several times...”

(”The Corpuscular Theory of Matter”, Constable, London, 1907)

E. Rutherford: - ex-student and ex-assistant of J. J. Thomson

- took a chair of physics at Manchester University in 1907 - in 1908-1911 showed that planetary model was more appropriated, i.e. atomic nucleus is positively charged and electrons are in orbits

 Rutherford’s model of atom N. Bohr spent in 1912: - 7 months with Thomson in Cambridge

- 3 months with Rutherford in Manchester

 Bohr’s model of atom

H. V. Gill emphasized that this model of atom should be named “Boscovich-Thomson” model of atom: “J. J. Thomson deducted his hypothesis directly from the theory of Boscovich, and showed that the notion of “allowed” and “forbidden” orbitals follows from it, and this laid the foundations of the theory developed later by Bohr and others”. “Where Boscovich planted two hundred years ago – other have reaped”. “Roger Boscovich, S. J., - Forerunner of Modern Physical Theories”, M. H. Gill and Sons. Dublin, 1941.

Verifications of Boscovich's “Theory of natural philosophy” by modern science

The most important question is:

Has been Boscovich’s curve (force vs. distance) confirmed by modern science?

Electrons

"In a such way atoms might be formed like spirals; and, if these spirals were compressed by a force, there would be experienced a very great elastic force or propensity for expansion." Theory, paragraph 440

Boscovich

Leon Lederman (Nobel prize laurate for physics, 1988) stated in the book “The God Particle” published in 1993: Roger Boscovich had an idea, totally foolish for 18th century (and perhaps for any other century)... “Boscovich claimed, in 18th century, that matter is built from the particles that have no dimensions! 20 years ago we found a such particle and named it – quark.” Lederman: Boscovich’s Theory, however, is “a key for the entire modern physics!”

Concluding remarks

Boscovich’s quantum Theory had the great contributions to: - Discovery of structure of matter but also to the other scientific fields: • Particle theory • Electric and magnetic field theory • Quantum mechanics • Theory of relativity...

Was Boscovich just a visionary, a prophet, a magic man? NO!

Acceptance of Boscovich’s Theory In the time of Boscovich: - Euler

A great number of Boscovich’s Followers and Supporters

- Lagrange - dAlambert - Laplace

In 18th and 19th century in institutions that now belong to - Austria - Hungary - Croatia - Italy - Germany - Poland - England

- Amper - Caushy - Fehner - Priestley - Gay-Lisak - Faraday - Kelvin - Thomson

- Mendeljejev - Helmholz - Henry - Maxwell - Lorenz - Davy - Bohr - Heisenberg

They have built the modern science using the foundations given by Boscovich!

Procedure of scientific research: Hypothesis

matter - Law of forces

Molecules Macromolecules

Reappearance of Boscovich Theory: - Hierarchy of matter - Law of forces

Bodies...

Boscovich is founder and promoter of modern sciences

Niels Bohr (1958): - Boscovich developed a systematic account of the properties of matter - His ideas exerted a deep influence at the work of the next generation of physicists: Laplace, Faraday and Maxwell - His great scientific work... served to pave the way for later developments.

Werner Heisenberg (1958): - The remarkable concept that forces are repulsive at small distances, and have to be attractive at greater ones, has played a decisive role in modern atomic physics. - His main work, Theoria Philosophiae Naturalis, contains numerous ideas which have reached full expression only in modern physics of the past fifty years, an which show how correct were the philosophical views which guided Boscovich in his studies in the natural sciences.

Leon Lederman (1993): - His theory is

a key for the entire modern physics.

We suggest to you: Be introduced with Boscovich’s Theory in order to:  recognize it in the current science achievements  use it in own research as we have done 1. Download free electronic books: Google → Dragoslav Stoiljkovic ResearchGate 2. Buy printed books from by publishers
