A
thing used in
quantum mechanics to describe
fields of
probability.
Analogy:
Let's say you've got a (slightly)ditzy boy/girlfriend, and you're at the mall. You stop at a Subway to get a sandwich or something, and when you turn around, your boy/girlfriend is gone. Now, you have two options at this point:
- Run around knocking people over, screaming his/her name, until you get desperate and call Security,
OR:
- Reflect on your SO's basic nature. Realize that he/she likes shoes/jewelry. Construct a wave packet and superimpose it on a map of the mall, making sure high-probability areas are centered on Foot Locker and Zales.
Congratulations! You've just used a wave packet to find your boy/girlfriend! Now, leave him/her there, and look at Everything Personals.
