Many Brazilian side streets go for a VERY long time without a right or left side turn exit. This one goes on for about a mile before you get a choice! In the states a typical residential neighborhood would have side streets every 300 feet or so.
I have a friend who has very quick hands. We'll call him Hans. One day Hans said I'm so fast I can catch birds and squirrels with my bare hands. So we found a squirrel in the park and he crept up all stealthy like a cat. Then in a flash his hands grabbed the squirrel but somehow managed to get an incomplete grip. The Mr. Rocky J. Squirrel was instantly in defense mode and sunk his teeth into his mid-finger knuckly quite deep as they have long teeth. Hans was there in the park waving his hand with Mr. Squirrel flailing and luckily let go after a short bit. It was quite a show. I have not laughed so hard in a long time in spite of the fact it could be bad for my friends health having squirrel germs dead square in his finger joint.
When doing hard core high testosterone engineering I learned something about my machine. Designing cutting edge RF circuit cards was a highly constrained exercise in the use of imagination for creativity. Highly constrained creativity is the type Richard Feynman talked about when he talked about creativity and physics. He liked it more because it was creativity and imagination you could actually DO something with other than write yet another BS filled science fiction movie with John Travolta in alien drag. Imagine you are working on a highly constrained creativity project. You start packing your head full of all the constraints. For example you want to design a new car. The constraints might be: 1- have 4 wheels 2- get 200 miles per gallon 3- plug in hybrid electric 4- use gasoline, alcohol 5- go 200 miles per hour What I discovered was that if you pack your head full of all the information about a design task for 3 days straight on the 3rd day is when you start to get the really good ideas. Up till then the results of your constraints and your imagination are not fully cooked.
One of the funniest crook stories I ever heard was the story of how a ranger had been called out to capture and transfer a bobcat to a more appropriate location. The only thing the ranger had to put the bobcat in was a toolbox. He did so after capturing it and left it in his truck. While he was away from his truck a couple of car thieves made off with truck and contents. They found the truck skidded off of the road with the interior bloodied up. Seems the greedy crooks had opened the toolbox while driving. The bobcat was of course highly annoyed at having been in the box and proceeded to go medieval on them. Note this story was told to me in 1990 before the internet so it must be true.
Occurred to me while riding a bike
Have you ever wondered why the dumbell shape of the N=2 quantum state of the hydrogen atom. I have! The Schrodinger wave equation gives you the results. But WHAT are you looking at? I have finally solved the problem of understanding the shape of the solutions. I did it while riding a bicycle in front of the electric driveway door waiting for it to open. It opens like a standard garage door on a house. I hate to just sit their with my leg on the ground so I started by riding the bicycle in a circle as the door rises. When the door is fully open I ride in and park. You can see my orbit in the picture below:
One day the owner of the complex of houses was parked right in front of the door with the car extending into the street where I normally ride in a circle. I was thus constrained as show in the following diagram. The figure 8 felt most efficient given the contraint of not being able to go in a circle and wanting to loiter on spot until the path was clear. Maximum entropy principle wants to make my path as gentle as possible given the constaint of the circle not being allow. 
Riding my bicycle in a figure 8 pattern Thus it is with the N=2 orbital. The N=2 orbital in an unexcited atom is only filled when there is an electron already filling the circular N=1 orbit. This filled orbit is the constraint of the car in the bicycle example. Its taken a long time to know the WHY of this. I solved the schrodinger for the hydrogen atom a long time ago. But I did not understand the why. Now I am sure that this same method applies the the higher N Numbers. The N number is the number of wave lengths in a full orbital path. Since the dumbell shape requires 2 wavelengths minimum. I feel better now! The Schrodinger wave equation yields minimum time / maximum entropy solutions. From this I deduce that an electron when in a state in an atom it is in Free-fall. Free fall is the condition of minimum time. However in free-fall there is no force on the particle. Also noting that accelerated charges radiate leads me to the conclusion that indeed the electron is spread out into the entire space of the orbital and not just a billiard ball whipping around in an orbit. This is very much a standing still wave. Why doesn't the electron just fall down onto the proton of the hydrogen atom? I think that might be due to the electron not liking to be stuffed into too small of a box. The electron most likely can sit on the proton with some probability but since it would undergo massive "compression" to do so it has an extremely high probability of leaking out of this state and into the N=1 state to get jiggy with it.
