Life sciences, ranging from oceanography to psychiatry, inform two programs at The Church in Sag Harbor this weekend. The Knowledge Friday series, set for Friday at 6 p.m., will feature Steve Bechard, an accomplished fisherman, and Tim Regan, an ocean videographer, for "a visual foray into the beautiful art of fly fishing and the waters of the East End."
Mr. Bechard, the president of Rise Fishing Co., a supplier of rods and gear, has put his fly-fishing skills to the test, competing in several "Great Outdoor Games" on ESPN, and he has used his knowledge and abilities to teach others.
Mr. Regan is a guide for Rise Fishing and a certified drone pilot. A field editor for On the Water magazine, he will share photos of life in the water, from schools of fish to whales breaching.
Tickets are $10, free for members, who are required to R.S.V.P.
The third annual Creativity Conference at The Church, a daylong exploration by six leading thinkers about creativity in the arts and sciences, will happen on Saturday from 9 a.m. to 6 p.m.
Saturday's speakers are Mark Epstein, a psychiatrist; Rachel Herz, a psychologist; Heather Lynch, an ecologist; Seth Ruffins, a biologist; Scott Small, a physician, and Sarah Thornton, a sociologist. Each speaker will reflect on his or her own practice and life. The individual presentations will be followed by a group panel discussion and question-and-answer session.

"In Defense of Anthropocentrism in the Anthropocene" is the subject to be tackled by Dr. Lynch, the director of the Stony Brook University Collaborative for the Earth and a Pew Marine Conservation Fellow.
Dr. Ruffins, director of the Optical Imaging Facility at the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Science in California, will discuss "The Intricate Art of Nature."
