1) Turn in an electronic version of your timeline and references in Adobe acrobat pdf format to the personal storage space on ASULearn. On a Mac you can print to a pdf file. https://www.pdfonline.com/convert_pdf.asp also converts files to pdf. I will make your pdf publicly available.
2) Bring a printed version to class to post on the wall [I will bring tape].
3) We will divide up the class into two sessions (half the class will be next to the timeline as the other half examines them, and then we will switch roles). During your session, you must stand by your timeline to chat and answer questions. If you work with another person, they will be in the other session.
Here is a sample timeline from another class, which incorporates pictures of the related mathematicians.
Your topic will be approved on a first-come-first-served basis as a message to me on ASULearn. There is a maximum of 2 people per topic (you can work individually or together). Other topics may be approved if they relate to course topics and have a rich history.
Websites such as the MacTutor History of Mathematics archive (O'Connor and Robertson, 2005) provide an extensive collection of articles on particular people and topics. The Earliest Known Uses of Some of the Words of Mathematics (Miller, J, 2008) can provide history on the development as well as the first published appearance of terms such as the Klein bottle. Other pages, such as Wikipedia's History of geometry can also be useful.
Some topic searches may yield many unrelated pages or be too general a search - for example, surfaces means many different things in real-life. However, modifying a search for information related to specific surfaces like the Klein bottle, torus, cylinder, often results in history within those pages. The "history of spherical geometry" will often yield information on the history of the sphere.
Similarly, the history of similarity might be too general a search. A modified search such as the history of "similar triangles" can be more productive and it leads to a mathematics history journal article Proportionality in Similar Triangles: A Cross-Cultural Comparison
As always, I is happy to help in office hours or on ASULearn.
