  Brouwer biography
Brouwer was elected to the Royal Academy of Sciences in 1912 and, in the same year, was appointed extraordinary professor of set theory, function theory and axiomatics at the University of Amsterdam; he would hold the post until he retired in 1951.
Brouwer was somewhat like Nietzsche in his ability to step outside the established cultural tradition in order to subject its most hallowed presuppositions to cool and objective scrutiny; and his questioning of principles of thought led him to a Nietzschean revolution in the domain of logic.
Brouwer's projected reconstruction of the whole edifice of mathematics remained a dream, but his ideal of constructivism is now woven into our whole fabric of mathematical thought, and it has inspired, as it still continues to inspire, a wide variety of inquiries in the constructivist spirit which have led to major advances in mathematical knowledge.

Brouwer was an unsalaried lecturer at the University of Amsterdam (1909), and was professor of set theory, function theory and axiomatics there from 1912 to 1951.
Brouwer was a major contributor to the theory of topology and was considered by many to be its founder.
Brouwer's doctrine differed substantially from the formalism of David Hilbert and the logicism of Bertrand Russell.

 Dirk Brouwer
Brouwer studied astronomy at the University of Leiden, and did his doctoral dissertation on data collected and observations made of the four large satellites of Jupiter.
Brouwer then was able to determine that the mass of Titan, a moon of Saturn, could be determined from its influence on other Saturnian moons.
During the early periods of the artificial satellites, Brouwer computed their orbits and from the data collected, was able to develop a better understanding and knowledge of the figure of planet earth.

 Dirk Brouwer Summary
Brouwer was also a pioneer in the use of (then) high-speed digital computers for solving problems in celestial mechanics, many of which found practical application with the launching of artificial satellites in the late 1950s and early 1960s.
For his contributions to astronomy, Brouwer was awarded the Gold Medal of the Royal Astronomical Society in 1955.

The gradual addition of the sedimentary layers in the crater tended to compact the under-laid rubble layer causing the bottom of the shallow sea occupying the crater to sink.

From the observation tower at Muskwa Lake on the southern rim (#1) the Brent Crater is visible to the north and northwest.

Brouwer is a large lunar crater that is located in the southern hemisphere on the far side of the Moon.
Intruding into the western rim of Brouwer is the younger and somewhat smaller Langmuir crater.
This is an old crater formation with a rim that has been heavily worn due to subsequent impacts.

Born in the Netherlands, Dirk Brouwer received his Ph.D. in 1927 under Willem de Sitter at the University of Leiden and then joined the faculty at Yale University, where he worked in celestial mechanics with Ernest W. Brown.
Brouwer developed general methods for finding orbits and computing errors and applied these methods to comets, asteroids, and planets.
He was one of the first to use electronic computers for astronomical computations.

Shown in the image are Duck Bay, the eroded segment of the crater rim where Opportunity first arrived at the crater; Cabo Frio, a sharp promontory to the south of Duck Bay; and Cape Verde, another promontory to the north.
Others have proposed that craters in icy targets may relax and degrade over time, and the aim of this work was to model this process on Titan.
Only the largest crater sizes show significant relaxation on reasonable time scales, so these results suggest that other factors may be responsible for the lack of craters.

Most of the crater was long ago folded into the planet or eroded away.
Shocked quartz, which is generally thought to be indicative of a forceful impact, has been found at the K-T boundary, and a 125- mile-wide impact crater found in Mexico that dates to 65 million years ago provided further compelling support.
