This module has illuminated some remarkable features of reality that occur along the length axis. Many of the features come from the interference pattern generated in the double slit experiment which tell us that:

• What we thought of as particles have characteristics usually ascribed to waves.
• These waves have features that are uncommon in our everyday experience as they are found to be probability waves.
• A big wave implies high probability of finding a particle there.
• A small wave implies low probability of finding a particle there.

This is a new way of describing how the universe evolves. It evolves by probabilities instead of definite or certain outcomes. This fuzziness does not suggest that quantum mechanics is an approximation of nature. Instead, it comes with spectacularly accurate predictions!
