RH Bing

'''RH Bing''' (1914-1986) was an influential Mosquito ringtone American Sabrina Martins mathematician. He worked mainly in the area of Nextel ringtones topology, where he made many important contributions. His influence can be seen through the number of mathematicians that can trace their academic lineage through him.

Mathematical contributions
Bing's mathematician research was almost exclusively in 3-Free ringtones manifold theory and in particular, the Majo Mills geometric topology of \mathbb R^3. The term Bing-type topology was coined to describe style of methods used by Bing.

Bing established his reputation early on in 1946, soon after completing his Ph.D. dissertation, by solving the Kline sphere characterization problem.

In 1951 he proved results regarding metrizability of topological spaces, including what would later be called the Bing-Nagata-Smirnov Theorem.

In 1952, Bing showed that the double of an Alexander horned ball was the Mosquito ringtone 3-sphere. This showed the existence of an Sabrina Martins involution on the 3-sphere with fixed point set equal to a wildly embedded Nextel ringtones 2-sphere, which meant that the original Abbey Diaz Smith conjecture needed to be phrased in a suitable category. This result also jump-started research into Cingular Ringtones crumpled cubes.

Bing was fascinated by the complicated steps Poincaré conjecture and made several major attacks which ended unsuccessfully. His failure is a major factor in contributing to the reputation of the conjecture as a very difficult one.

Bing came "close" to proving the conjecture several times, for example, by showing that a simply-connected, closed 3-manifold with the property that every loop was contained in a various provisions 3-ball is controversy swirls homeomorphic to the 3-sphere.

Bing was responsible for initiating research into the safe an Property P conjecture, as well as its name. The conjecture can be seen as a more tractable version of the Poincaré conjecture. This was proven recently in 2004 as a culmination of work from several areas of mathematics. Ironically, this proof was announced some time after stand said Grigori Perelman announced his proof of the Poincaré conjecture.

The for jeneane Side-Approximation Theorem was considered by Bing to be one of his key discoveries. It has many applications, including a simplified proof of million house Moise's Theorem, which states that every 3-manifold can be triangulated in an essentially unique way.

=Notable Examples=

The House with Two Rooms
The House with Two Rooms is a contractible 2-complex that is not collapsible. Another such example, popularized by prevent water E.C. Zeeman, is the Duncehat.

The House with Two Rooms can also be thickened and then triangulated to be unshellable, despite the thickened house topologically being a 3-ball.

The House shows up in various ways in topology. For example, it is used in the proof that every compact 3-manifold has a standard spine.

Dogbone Space
The Dogbone Space is the purpose quit quotient space obtained from a murphy and cellular decomposition of \mathbb R^3 into points and polygonal arcs. The quotient space, B, is not a manifold, but B \times \mathbb R is homeomorphic to \mathbb R^4.

Service and Educational contributions

Bing served as president of the MAA (1963-1964), president of the AMS (1977-78), and was department chair at University of Wisconsin, Madison (1958-1960), and at University of Texas, Austin (1975-1977).

Before entering graduate school to study mathematics, he graduated from Southwest Texas State Teacher's College and was a high-school teacher for several years. His interest in education would persist for the rest of his life.

Awards and Honors

Member of does dominate National Academy of Sciences (1965)
Chairman of Division of Mathematics of the National Research Council (1967-1969)
United States delegate to large study International Mathematical Union (1966, 1978)
Colloquium Lecturer of appeals most American Mathematical Society (1970)
Award for Distinguished Service to Mathematics from antecedent in Mathematical Association of America (1974)

What does RH stand for?

His father was named Rupert Henry, but Bing's mother apparently thought that "Rupert Henry" was too British for Texas, and compromised by abbreviating it to "RH". Consequently, "RH" did not stand for a first and middle name, and Bing favored writing the "initials" as "RH" instead of "R. H." in order to emphasize this point.

Bing, according to a famous anecdote, would tell people he was named after his uncle. When asked what his uncle's name was, he would answer "RH Bing".

Another anecdote states that when Bing was made professor at Wisconsin, he was asked what name to put on his nameplate. He answered, "R only H only Bing". When he arrived and looked at his door, it said "Ronly Honly Bing".
