In the late 1800s, the world became a seemingly magical place. Scientists discovered radiation, radio waves, and other invisible forces of nature. For a while there, many serious researchers joined seances and believed in ghosts. Science had discovered so many mysterious phenomena – things that the eye could not see but were definitely there – that many people wondered, what else might be out there?

German physicist Wilhelm Röntgen discovered one of these invisible powers by accident. 

Röntgen experimented with cathode-ray tubes, basically glass tubes with the air sucked out and a special gas pumped in. They work kinda like modern-day fluorescent light bulbs. When Röntgen ran electricity through the gas, the tube would glow. But something strange happened after he surrounded the tube with black cardboard. When he turned on the machine, a chemical a few feet away started to glow. The cardboard should have prevented any light from escaping, so what caused this distant glow? 

Little did he know that the cathode-ray tube had been sending out more than just visible light. It shot out invisible rays that could pass right through paper, wood, and even skin. The lab chemical that lit up – the one that tipped off Röntgen – reacted to these rays. He called the phenomenon X-rays. The X stood for "unknown."  

Röntgen went on to capture the first X-ray images, including a shot of his wife's hand (pictured, above). Upon seeing this skeletal image, she exclaimed, "I have seen my own death!"

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”
