Mathematical methods used by Halley and Horrocks for Venus transits

[Adrian Baker]

Hi there

I'm looking for a source of the maths that Halley did, and also that of Horrocks so that I can run through it with some Maths/Physics students.

Google searches have given many different sites, but none have been that good so far.

If anyone could help me with a link, I'd appreciate it.

Thanks

Have you looked at http://sunearth.gsfc.nasa.gov/sunearthday/2004/2004images/VT_Activity3.pdf ? It's somewhat ahistorical, but it does cover the simple geometric methods.

Thanks so much selfadjoint - that will be absolutely great. :-)

I'm printing it out as we speak...
