PseudomathematicsPseudomathematics is a form of mathematics-like activity undertaken primarily by non-mathematicians. The word is adapted from the term pseudoscience, which is applied to ideas that purport to be scientific but are not. The efforts of pseudomathematicians may be divided into three broad categories: - Attempting to solve classical problems posed in terms that have been proved mathematically impossible;
- Generating new theories of mathematics or logic from scratch;
- Taking on difficult problems in mathematics using only high-school mathematical knowledge.
Investigations in the first category are doomed to failure. Those in the second are generally unproductive, as they tend to re-invent existing knowledge at best, and to create complete nonsense at worst; some forms of numerology fall under this category. Efforts in the third category are not necessarily futile since some advanced mathematical results can be proved using more elementary techniques; there is no coherent notion of depth in mathematics. However, unless the investigator possesses a deep intuitive understanding of the subject matter, the probability of achieving a breakthrough is small. Pseudomathematics has equivalents in other scientific fields, particularly physics, where amateurs continually attempt to invent perpetual-motion devices, disprove Einstein using classical mechanics, and other similarly impossible feats. Excessive pursuit of pseudomathematics can create mathematical cranks, who regard mainstream mathematicians with suspicion bordering on paranoia because their ideas are continually rejected. The topic has been extensively studied by Indiana mathematician Underwood Dudley, who has written several popular works on the topic. In addition, Clifford Pickover considers the "link between genius and madness" among scientists and mathematicians in his 1998 book, Strange Brains and Genius. Impossible problems Examples of impossible problems include the following constructions in Euclidean geometry using only a ruler and compass: For 2,000 years people have tried and failed to find such constructions; the reasons were discovered in the 19th century, when it was proved that they are all impossible. Rather than discouraging pseudomathematicians, however, such statements of impossibility by orthodox mathematicians tend merely to inspire more attempts. Current trends in pseudomathematics In recent years, pseudomathematicians have devoted their energies to disproving Gdel's second incompleteness theorem (efforts that fall in the first category mentioned above) and to proving Fermat's last theorem using elementary mathematical techniques (third category). The latter theorem now has a lengthy and extremely technical orthodox proof drawing on many different areas of advanced mathematics. It is particularly tempting for amateur mathematicians, because a note in Fermat's papers claimed that he had developed an elementary proof for it. Other related activities include attempts to create lossless data compression algorithms which will compress all possible inputs or to disprove the four-color theorem; both of these belong to the first category of problems proven to be impossible. In the former case, there's a trivial proof of impossibility — such an algorithm would need to map a large set of input onto a small set of output on a one-to-one basis. Other favorite subjects of pseudomathematicians include the indeterminate expression 0/0, the meaning of infinity, and the nature of complex numbers. See also
