Upcoming Meetings

Saturday, March 16, 2019 - The Workshop and the World: what ten thinkers can teach us about Science and authority

Time: 2:00 PM
Location: Community College of Philadelphia, Room C2-28 Details
Speaker: Bob Crease

"The Workshop and the World - what ten thinkers can teach us about Science and authority" is born out the current zeitgeist of frustration with what seems a growing trend of denying Science.  The following is a review of the book: 
An eloquent, timely account of what went right and what wrong in modernity when it comes to the ways in which scientific discoveries and theories were received by contemporaries. In lively recountings of telling episodes, Crease discusses a rich array of figures ranging from Francis Bacon and Galileo to Edmund Husserl and Hannah Arendt. He demonstrates how earlier forms of casting doubt on the authority of scientific findings offer clues to contemporary ways by which this authority is put in question. Speaking forcefully to the present moment, Crease spells out a series of concrete and efficacious steps by which science denial can be addressed and combated in our own time.
Bob Crease is Chair of the Department of Philosophy Stony Brook University, Columnist of Physics World, Co-Editor-in-Chief of Physics in Perspective and written or translated over a dozen books on the history and philosophy of Science and technology.  He will give a lecture on his latest book "The Workshop and the World" which will be followed by a book signing.

Saturday, May 18, 2019 - Hike to Indian Rock @ Tyler Arboretum

Time: 10 am
Location: Tyler Arboretum Details
Speaker: Don Nigroni
At Tyler Arboretum in Delaware County by the picturesque Rocky Run sits a peculiar artifact known, at least since 1907, as Indian Rock. Our guide, Don Nigroni, will relate the theories as to what Indian Rock might really be and we will discuss the local history of the Lenape and a strange document, the Walum Olum, ascribed to them. Robb Kerr will be providing botanical information about this scenic Piedmont site and Kim Sheridan will be photo-documenting the day's activities.
We will meet at the Visitor Center by the parking lot at 10:00 AM, then we will hike from the Visitor Center along the Blue Trail for one mile each way to inspect this mysterious stone. Although we may not figure out what Indian Rock really is, we will learn about the history and natural history of this Piedmont site.
Bring insect repellent, sturdy shoes, water, lunch, and a camera.
