Dear Sir

I have to acknolege the reciept of your favor of May 14. in which you mention that you have finished the 6.first books of Euclid, plane trigonometry, surveying & algebra and ask whether I think a further pursuit ofthat branch of science would be useful to you. there are some propositions in the latter books of Euclid, & someof Archimedes, which are useful, & I have no doubt you have been made acquainted with them. trigonometry,so far as this, is most valuable to every man, there is scarcely a day in which he will not resort to it for some ofthe purposes of common life. the science of calculation also is indispensible as far as the extraction of thesquare & cube roots; Algebra as far as the quadratic equation & the use of logarithms are often of value inordinary cases: but all beyond these is but a luxury; a delicious luxury indeed; but not to be indulged in byone who is to have a profession to follow for his subsistence. in this light I view the conic sections, curves of thehigher orders, perhaps even spherical trigonometry, Algebraical operations beyond the 2d dimension, andfluxions. Letter from Thomas Jefferson to William G. Munford, Monticello, June 18, 1799.
