Quotes & Sayings About Primary Data

Lately we have been getting facts pointing to the "oceanic" nature of the floor of so-called inland seas. Through geological investigations it has been definitely established that in its deepest places, for instance, the Caribbean Sea and the Gulf of Mexico, the Earth's crust is devoid of granite stratum. The same may be said quite confidently about the Mediterranean and the Black Sea. Could the interpretation of these data be that inland seas were the primary stage of the formation of oceanic basins? — Vladimir Belousov

Hildebrand, too, challenged the ideals of scientific naturalism by an appeal to the psychology of perception: if we attempt to analyze our mental images to discover their primary constituents, we will find them composed of sense data derived from vision and from memories of touch and movement. A sphere, for instance, appears to the eye as a flat disk; it is touch which informs us of the properties of space and form. Any attempt on the part of the artist to eliminate this knowledge is futile, for without it he would not perceive the world at all. His task is, on the contrary, to compensate for the absence of movement in his work by clarifying his image and thus conveying not only visual sensations but also those memories of touch which enable us to reconstitute the three-dimensional form in our minds. — E.H. Gombrich

I know very little with anything approaching certainty. I know that I was born, that I exist, and that I will die. For the most part, I can trust my brain's interpretation of the data presented to my senses: this is a rose, that is a car, she is my wife. I do not doubt the reality of the thoughts and emotions and impulses I experience in response to these things. . . . Yet apart from these primary perceptions, intuitions, inferences, and bits of information, the views that I hold about the things that really matter to me--meaning, truth, happiness, goodness, beauty--are finely woven tissues of belief and opinion. — Stephen Batchelor

It is really hurting; how big media plagiarize everyday and no one judges them; The real heroes are those tiny and small self-funded websites and blogs that provide all primary data for them to survive and it will continue as far they exist — M.F. Moonzajer

The situations depicted in the Book of Changes are the primary data of life
what happens to everybody, every day, and what is simple and easy to understand. — Hellmut Wilhelm

And what is the primary datum? It's the felt presence of immediate experience. In other words, being here now is the primary datum. — Terence McKenna

Index design is also a largely iterative process, based on the SQL generated by application designers. However, it is possible to make a sensible start by building indexes that enforce primary key constraints and indexes on known access patterns, such as a person's name. As the application evolves and testing is performed on realistic sizes of data, certain queries will need performance improvements for which building a better index is a good solution. — Andrew Holdsworth

The programmer's primary weapon in the never-ending battle against slow system is to change the intramodular structure. Our first response should be to reorganize the modules' data structures. — Fred Brooks
