When science seems like Magic

In December 1903 (only an incredible 120 years ago) the Wright brothers had their first powered flight, traveling 37 metres. By the fourth flight they reached 260 metres and lasted just under a minute in the air. Today a Boeing 787-8 is fifty-seven metres long and can reliably fly for more than 13,500 kilometers carrying…

Chatting with ChatGPT

Nearly 20 years ago, when I was completing a PhD in computer vision, I was drawn to an AI technique called “machine learning” for recognizing different images. I recall being astounded at the profound elegance of “training” a computer with example images and then observing how well it could identify new images. My early experiences…

Finding the fakes

“Computers: Are they conquering our world?” That was the title of an article published in Christian Courier (CC) more than 40 years ago. “The possibilities for manipulation of people,” columnist and labour expert Harry Antonides wrote in 1982, “by controlling and slanting information and news via the new systems of communication are staggering.” He was…

Clean fusion?

In mid-December, scientists for the first time reported a successful nuclear fusion experiment that produced more energy than made it happen. A friend who is a physics professor at the University of Waterloo was bubbling with excitement when he shared its implications with me. Ever since I was in high school, about 60 years ago,…

Could you tell if this editorial was written by a robot? I started asking this question in mid-December right around the time my husband, Jakob was spending his evenings talking to something (someone?) who wasn’t human at all. He had discovered ChatGPT, a large language model developed by OpenAI, a company co-founded by Elon Musk….

Solving murder with DNA

Solving murder with DNA

In late November, many Canadian newspapers reported that police had solved two 39-year-old murder cases using new genetic technology. The technology led to a single suspect who was not initially a person of interest. Further genetic confirmation (using a court-issued DNA warrant) led to the arrest of the individual, who remains only a suspect until…

Human Neurons, Rat Brains

What does it mean to be made in the image of God? New research on human brain neurons implanted in rats forces us to ask this question. The cells of adult humans can be reprogrammed to act as stem cells, and stem cells can then become any of the different cell types found throughout our…

There is a labyrinth in the cathedral of Chartres in France. The centre of the labyrinth is reached by walking (or going on your knees) on a deceptively long path. Look up, and you will see a mirror copy in the great West Rose of stained glass above. The centre of the West Rose is…

Tech leaps in the Global South

“Never limit yourself because of others’ limited imagination.” This quote from Dr. Mae Jemison, the first Black woman astronaut in space, reminds me that we serve a God whose creativity and power reaches far beyond our imaginations. But I have often limited others, boxing them into my tiny vision of what was possible. In 2005,…
