Dodd, Mead and company. Act I The first act opens in London, where Richard, Duke of Gloucester, states in a soliloquy, the winter of discontent is over, and the sun of York shines upon a glorious summer.
This chapter is almost exactly the same as Chapter 37 of Volume I. Things on a very small scale behave like nothing that you have any direct experience about. They do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen.
Newton thought that light was made up of particles, but then it was discovered that it behaves like a wave. Later, however in the beginning of the twentieth centuryit was found that light did indeed sometimes behave like a particle. Historically, the electron, for example, was thought to behave like a particle, and then it was found that in many respects it behaved like a wave.
So it really behaves like neither. Now we have given up. They finally obtained a consistent description of the behavior of matter on a small scale.
We take up the main features of that description in this chapter.
Because atomic behavior is so unlike ordinary experience, it is very difficult to get used to, and it appears peculiar and mysterious to everyone—both to the novice and to the experienced physicist.
Even the experts do not understand it the way they would like to, and it is perfectly reasonable that they should not, because all of direct, human experience and of human intuition applies to large objects.
We know how large objects will act, but things on a small scale just do not act that way. So we have to learn about them in a sort of abstract or imaginative fashion and not by connection with our direct experience.
In this chapter we shall tackle immediately the basic element of the mysterious behavior in its most strange form. We choose to examine a phenomenon which is impossible, absolutely impossible, to explain in any classical way, and which has in it the heart of quantum mechanics.
In reality, it contains the only mystery. We will just tell you how it works.
In telling you how it works we will have told you about the basic peculiarities of all quantum mechanics. Interference experiment with bullets.
To try to understand the quantum behavior of electrons, we shall compare and contrast their behavior, in a particular experimental setup, with the more familiar behavior of particles like bullets, and with the behavior of waves like water waves.
We consider first the behavior of bullets in the experimental setup shown diagrammatically in Fig. We have a machine gun that shoots a stream of bullets.
It is not a very good gun, in that it sprays the bullets randomly over a fairly large angular spread, as indicated in the figure. In front of the gun we have a wall made of armor plate that has in it two holes just about big enough to let a bullet through.
It might be a box containing sand. Any bullet that enters the detector will be stopped and accumulated. When we wish, we can empty the box and count the number of bullets that have been caught.
With this apparatus, we can find out experimentally the answer to the question: A bullet which happens to hit one of the holes may bounce off the edges of the hole, and may end up anywhere at all. Or, if we assume that the gun always shoots at the same rate during the measurements, the probability we want is just proportional to the number that reach the detector in some standard time interval.
For our present purposes we would like to imagine a somewhat idealized experiment in which the bullets are not real bullets, but are indestructible bullets—they cannot break in half. In our experiment we find that bullets always arrive in lumps, and when we find something in the detector, it is always one whole bullet.
If the rate at which the machine gun fires is made very low, we find that at any given moment either nothing arrives, or one and only one—exactly one—bullet arrives at the backstop. Also, the size of the lump certainly does not depend on the rate of firing of the gun.
The effect with both holes open is the sum of the effects with each hole open alone.26 August Immediate release 26 August The battlefield of Bosworth under threat.
The Richard III Society, along with many others such as The Battlefields Trust, is appalled to learn of the planning application by Horiba Mira Ltd to build a testing facility for driverless cars on part of the site of the historic battle of Bosworth where in King Richard III lost his life and crown.

There is one lucky break, however—electrons behave just like light. The quantum behavior of atomic objects (electrons, protons, neutrons, photons, and so on) is the same for all, they are all “particle waves,” or whatever you want to call them.
