**Contributions:**

- Elementary Investigation of the Theory of Numbers 1811
- The Barlow Tables were published In 1814. When initially released, these tables were called 'New Mathematical Tables. The tables give factors, squares, cubes, square roots, reciprocals and hyperbolic logarithms of all numbers from 1 to 10 000. Peter Barlow was known for his attention to detail and accuracy. The tables were used repeatedly and were reprinted several times. If not for computers and calculators, they would be used today due to their accuracy. In fact, they are still available!
- The Barlow Lens, a well known device to amateur astronomers.
*(Peter Barlow did a lot of experimenting with optics.)*

**Famous Quote:**

"2^{30}(2^{31}-1) is the greatest perfect number that will ever be discovered, for, as they are merely curious without being useful, it is not likely that any person will attempt to find a number beyond it.

*(*Quoted in D MacHale, Conic Sections (Dublin 1993) *)*
