Let it be remarked ... that an important difference between the way in which we use the brain and the machine is that the machine is intended for many successive runs, either with no reference to each other, or with a minimal, limited reference, and that it can be cleared between such runs; while the brain, in the course of nature, never even approximately clears out its past records. Thus the brain, under normal circumstances, is not the complete analogue of the computing machine but rather the analogue of a single run on such a machine. We shall see later that this remark has a deep significance in psychopathology and in psychiatry.

While it is never safe to affirm that the future of Physical Science has no marvels in store even more astonishing than those of the past, it seems probable that most of the grand underlying principles have been firmly established and that further advances are to be sought chiefly in the rigorous application of these principles to all the phenomena which come under our notice. It is here that the science of measurement shows its importance - where quantitative work is more to be desired than qualitative work. An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals.

In common with my colleagues, I recognise that no single remedy can be a complete cure, but while I am ready to examine every proposal...I must frankly say that I believe a tariff levied on imported foreign goods will be found to be indispensable...The ultimate destiny of this country is bound up with the Empire...I hope to take my part in forwarding a policy which was the main subject of my father's last great political campaign...I hope that we may presently develop into a National Party, and get rid of that odious title of Conservative, which has kept so many from joining us in the past.

Heisenberg finds that facts of observation lead uniquely and inevitably to the theoretical structure known as matrix mechanics. This shows that the total radiation in any region of empty space can change only by a single complete quantum at a time. Thus not only in the photo-electric phenomenon, but in all other transfers of energy through space, energy is always transferred by complete quanta; fractions of a quantum can never occur. This brings atomicity into our picture of radiation just as definitely as the discovery of the electron and its standard charge brought atomicity into our picture of matter and of electricity.
James Jeans
When we view nature stripped to essentials, so to speak, in this Unification Table, what we see is... a five bit register. ...It is in just this form that data is stored and manipulated within a digital computer. ...Every particle, then, can be specified by a five-bit word and stored in a five-bit register. It's eerie that even the odd restriction on how many minus signs are allowed is reminiscent of a trick used in computers, to detect errors in transmission. You see, if allowed words must have an odd number of minus signs, any single error in transmission of a word can be detected. ...our world might be an intricate program working itself out on a gigantic computing machine.
Frank Wilczek
Early entry is appropriate when the following general circumstances hold:
- Image and reputation of the firm are important to the buyer, and the firm can develop an enhanced reputation by being a pioneer.
- Early entry can initiate the learning process in a business in which the learning curve is important, experience is difficult to imitate, and it will not be nullified by successive technological generations.
- Customer loyalty will be great, so that benefits will accrue to the firm that sells to the customer first.
- Absolute cost advantages can be gained by early commitment to supplies of raw materials, distribution channels, and so on.
