Mathematical Excursions

Mathematical Excursions: Side Trips along Paths Not Generally Traveled in Elementary Courses in Mathematics is a book on popular mathematics. It was written by Helen Abbot Merrill, published in 1933 by the Norwood Press,[1][2][3][4][5] and reprinted (posthumously) by Dover Publications in 1957.[6][7]

Topics

The book is devoted to mathematical puzzles and pastimes,[6] gathered from Merrill's experience as a teacher.[1][3] It has 15 chapters,[4] most on arithmetic and number theory but with one on geometry.[6]

Its topics include squared triangular numbers and other sums of powers,[5] Russian peasant multiplication,[2] binary numbers,[2][6] repeating decimals,[2] magic squares,[4] the irrationality of π,[2][5] mechanical linkages, linear Diophantine equations, the 15 puzzle,[6] perfect numbers,[7] and some unsolved problems in number theory.[2][5][6]

Audience and reception

The book is written for a general audience,[1] and is intended to spark the interest of high school students in mathematics.[4] In general, only high school levels of algebra and geometry are needed to appreciate the book and solve its problems.[1] It could be used as individual reading, or in mathematics clubs,[2] and also for mathematics teachers looking for examples and demonstrations for their classes.[5]

Of the original edition, reviewer David Eugene Smith wrote "the book ought to be in the hands of all teachers and on the shelves of all high schools and colleges".[3] By the time of the 1957 reprint, reviewer Samuel L. Greitzer complained about its obsolete notation, as well as its uneven level of exposition and non-uniform inclusion of solutions to problems,[6] and reviewer Roland Sprague noted that its treatment of perfect numbers was out of date.[7] Nevertheless, Greitzer suggested that it would be appropriate as "enrichment" for high-school students.[6]

gollark: Makes sense.
gollark: Hmm, so what extra features are needed?
gollark: Anyway, good news systemd-dislikers, I made an EXCELLENT and AMAZING replacement using the RUST programming language.
gollark: I have DashMap in here because of some vague dream of concurrently doing... stuff.
gollark: ```rustuse std::process::Command;use anyhow::Result;use std::path::Path;use std::fs;#[derive(serde::Serialize, serde::Deserialize, Debug)]struct RawServiceSpec { command: String, args: Vec<String>, name: Option<String>}#[derive(Debug)]struct ServiceSpec { command: String, args: Vec<String>, name: String}fn load_spec(path: &Path) -> Result<ServiceSpec> { let file = fs::read_to_string(path)?; let raw: RawServiceSpec = toml::from_str(&file)?; Ok(ServiceSpec { command: raw.command, args: raw.args, name: path.file_stem().unwrap().to_string_lossy().to_string() })}fn run_service(serv: ServiceSpec) -> Result<()> { println!("thread {:?}", serv); loop { println!("Starting"); let mut child = Command::new("/bin/env") .arg("python3") .arg("test.py") .spawn()?; child.wait()?; } Ok(())}fn main() -> Result<()> { let services = dashmap::DashMap::new(); for entry in fs::read_dir("./services")? { let s = load_spec(&entry?.path())?; services.insert(s.name.clone(), s); } let mut handles = Vec::new(); for e in services { handles.push(std::thread::spawn(|| run_service(e.1))); } for handle in handles { handle.join().unwrap(); } Ok(())}```
