While other philosophers have developed two-stage models, including William James, Henri Poincaré, Arthur Holly Compton, and Henry Margenau, Dennett defends this model for the following reasons:

After important contributions of Hendrik Lorentz and Henri Poincaré, in 1905, Albert Einstein solved the problem with the introduction of special relativity, which replaces classical kinematics with a new theory of kinematics that is compatible with classical electromagnetism.

Also in the last part of that century, Felix Klein and Henri Poincaré introduced a category of fractal that has come to be called " self-inverse " fractals.

In mathematics, more specifically algebraic topology, the fundamental group ( defined by Henri Poincaré in his article Analysis Situs, published in 1895 ) is a group associated to any given pointed topological space that provides a way of determining when two paths, starting and ending at a fixed base point, can be continuously deformed into each other.

Historically, the concept of fundamental group first emerged in the theory of Riemann surfaces, in the work of Bernhard Riemann, Henri Poincaré and Felix Klein, where it describes the monodromy properties of complex functions, as well as providing a complete topological classification of closed surfaces.

Cantor's theory of transfinite numbers was originally regarded as so counter-intuitive — even shocking — that it encountered resistance from mathematical contemporaries such as Leopold Kronecker and Henri Poincaré and later from Hermann Weyl and L. E. J. Brouwer, while Ludwig Wittgenstein raised philosophical objections.

As Henri Poincaré famously said, mathematics is not the study of objects, but instead, the relations ( isomorphisms for instance ) between them.

In 1905, Henri Poincaré was the first to recognize that the transformation has the properties of a mathematical group,

The work of Lorentz was mathematically perfected by Henri Poincaré who formulated on many occasions the Principle of Relativity and tried to harmonize it with electrodynamics.

Some notable mathematicians include Archimedes of Syracuse, Leonhard Euler, Carl Gauss, Johann Bernoulli, Jacob Bernoulli, Aryabhata, Brahmagupta, Bhaskara II, Nilakantha Somayaji, Omar Khayyám, Muhammad ibn Mūsā al-Khwārizmī, Bernhard Riemann, Gottfried Leibniz, Andrey Kolmogorov, Euclid of Alexandria, Jules Henri Poincaré, Srinivasa Ramanujan, Alexander Grothendieck, David Hilbert, Alan Turing, von Neumann, Kurt Gödel, Joseph-Louis Lagrange, Georg Cantor, William Rowan Hamilton, Carl Jacobi, Évariste Galois, Nikolay Lobachevsky, Rene Descartes, Joseph Fourier, Pierre-Simon Laplace, Alonzo Church, Nikolay Bogolyubov and Pierre de Fermat.

Originally conjectured by Henri Poincaré, the theorem concerns a space that locally looks like ordinary three-dimensional space but is connected, finite in size, and lacks any boundary ( a closed 3-manifold ).

At the beginning of the 20th century, Henri Poincaré was working on the foundations of topology — what would later be called combinatorial topology and then algebraic topology.

Special relativity ( SR, also known as the special theory of relativity or STR ) is the physical theory of measurement in an inertial frame of reference proposed in 1905 by Albert Einstein ( after the considerable and independent contributions of Hendrik Lorentz, Henri Poincaré and others ) in the paper " On the Electrodynamics of Moving Bodies ".

The history of special relativity consists of many theoretical results and empirical findings obtained by Albert Michelson, Hendrik Lorentz, Henri Poincaré and others.

The theorem was later utilized, popularized, generalized and further developed by James Clerk Maxwell, Lord Rayleigh, Henri Poincaré, Subrahmanyan Chandrasekhar, Enrico Fermi, Paul Ledoux and Eugene Parker.

The last exercise of Roland Claude's prescribed program for Henri is a single exercise, done in individual sets with a bit longer pause between sets.

It was during his early trips to Achill prior to the outbreak of World War I that Henri painted extensively and is reputed to have done portraits of almost all the children in Dooagh village.

Marker is often associated with the Left Bank Cinema movement that occurred in the late 1950s and included such other filmmakers as Alain Resnais, Agnès Varda, Henri Colpi and Armand Gatti.

Influential French critic M. Henri Rochefort commented, " I am compelled to admit, not without some chagrin, that not one of our female artists … is strong enough to compete with the lady who has given us this year the portrait of Dr. Grier.

From the only daughter of Camille, Jeanne Pissarro, other painters include Henri Bonin-Pissarro also known as BOPI ( 1918 – 2003 ) and Claude Bonin-Pissarro ( born 1921 ), who is the father of Abstract artist Frédéric Bonin-Pissarro ( born 1964 ).

Ignaz Goldziher is the best known of these turn-of-the-century critics, who also included D. S. Margoliuth, Henri Lammens, and Leone Caetani.

In chamber music, György Ligeti wrote a small number of solo works for the instrument ( including Continuum ), and Henri Dutilleux's Les Citations ( 1991 ) is scored for harpsichord, oboe, double bass and percussions.

In dealing with ' The Sorcerer ", the earliest evidence claimed, Murray based her observations on a drawing by Henri Breuil, which modern scholars such as Ronald Hutton claim is inaccurate.

There are many modern concepts of integration, among these, the most common is based on the abstract mathematical theory known as Lebesgue integration, developed by Henri Lebesgue.

The validity of the dating methodology has subsequently been called into question, and the age of the shroud is still the subject of much debate despite the existence of a 1389 Memorandum by Bishop Pierre D ' Arcis to the Avignon Antipope Clement VII mentioning that the image had previously been denounced by his predecessor Henri de Poitiers ( Bishop of Troyes 1353-1370 ), stating " Eventually, after diligent inquiry and examination, he discovered how the said cloth had been cunningly painted, the truth being attested by the artist who had painted it, to wit, that it was a work of human skill and not miraculously wrought or bestowed.

The present sovereign is Grand Duke Henri.

The effect is named for Henri Coandă, the Romanian aerodynamicist who exploited it in many of his patents.

In measure theory, the Lebesgue measure, named after French mathematician Henri Lebesgue, is the standard way of assigning a measure to subsets of n-dimensional Euclidean space.

For instance Joachim Patinir He was likely the uncle of Henri Blès who is sometimes defined as a Mosan landscape painter active during the second third of the 16th century ( i. e., second generation of landscape painters )

Henri Bergson, with his L ' évolution créatrice ( 1907 ), was one of the first to propose evolution is ' creative ' and cannot necessarily be explained solely by Darwinian natural selection.

When the invention became public, as revised by Henri Herz, the double escapement action gradually became standard in grand pianos, and is still incorporated into all grand pianos currently produced.

Two forefathers of project management are Henry Gantt, called the father of planning and control techniques, who is famous for his use of the Gantt chart as a project management tool ( alternatively Harmonogram first proposed by Karol Adamiecki ); and Henri Fayol for his creation of the five management functions that form the foundation of the body of knowledge associated with project and program management.
