In the big classroom, it was so quiet that even a single breath would be heard.
Once Lucien turned on the device, within the projection on the wall, many light spots appeared. They followed no order, No one could predict where the next light spot would show up.
There were more and more light spots. Heidi's mouth opened big out of surprise. In her eyes, there was this classic and beautiful interference image!
The arcanists took a deep breath from their surprise. There was no more doubt about an electron's wave properties. No pure particle theory could explain this.
"Double-slit interference of electrons…" said Douglas in a low voice at the back of the classroom. The experiment result was still bearable to him.
