Jeremiah 31:31-34 | Psalm 51:1-12 | John 12:20-33

One day in the year 1895, Wilhelm Roentgen, a little known professor of physics at the University of Wurzburg in Germany, was doing some experiments, as scientists tend to do. Roentgen was playing around with electrical currents, passing them through vacuum tubes. He noticed that the currents caused a fluorescent screen across the room to light up, despite the fact that there was a cardboard barrier between them.
