The Toronto Fringe Festival is in full swing, and as usual they have some science-themed plays.
This is what I found in the program. They all play multiple times during Fringe, so look up the exact times and locations on the website

HOLE
“A divine Physicist (Composer Chris Willes) assembles a cast of stellar Dancers and Musicians, guiding one woman through quantum possibilities in her soul’s multi-media trek”
(for mature audience)

Binary
“Welcome to the future: the environment is unlivable, babies are made in tubes, and gender has become obsolete. Binary is a 7 person ensemble about politics, science and love.”

Another Problem with H-theorem (no website)
(by “Molecular Chaos productions”)
“Time is a funny thing. Some people think it’s linear. Others know it isn’t. Mackenzie’s had a lot of time to think about time. Being trapped in his house for 147 years hasn’t been easy. But now he has a visitor. It’s his old friend/enemy Rolph. And Rolph’s been dead for 138 years.”

Einstein’s Wife
“In 1928, during a lecture at Cambridge University, Virginia Woolf famously asked, “What would have happened had Shakespeare had a wonderfully gifted sister?”
In Einstein’s Wife, her poignant question inspires the stories of three women: Jackie, a minor league pitcher, Rosalind, an x-ray crystallographer, and Wally, an aspiring astronaut.”
