Een etentje is datum plus restaurant plus drie personen. Een concert is datum plus venue plus artiest plus vrienden. Een optreden is datum plus locatie plus organisatie plus publiek. De entiteiten zijn de blokjes, de gebeurtenissen zijn de bouwsels.
Events zijn anders dan entiteiten. Een punt in tijd en plaats vgl [[Zijn VR virtual worlds leeg 20070917131806]]
what we've done since then uh uh is to increase the number of crystalline inorganic compounds that is minerals in every but formal sense at the earth's surface um uh by orders of magnitude so now more than 300,000 most of those have been made since 1950

the distinctionbetween an entity and an entity reference is fundamental tounderstanding ER.
Yeah because you can have multiple entity references to a real world entity and thats when ER comes into play
Although instances of an entity type are often called entitiesby data modelers, it is important to understand that in the con-text of ER, instances of an ERM entity type are not entities. Aninstance of an entity type, such as the Student entity type inFigure 1.1, is just a row in the Student database table inside thecomputer. The instance is only a reference to a real studentwalking around campus and attending classes. In an ER context,4 Chapter 1 PRINCIPLES OF ENTITY RESOLUTION
GRRR... this took me months to to figure out by myself -.- should have read this.
one cannot exclude that he's right the challenge is that the science is, really not is very inconclusive on, the cocktail risks of chemicals in the biosphere, but that is why we have it as one of the planetary boundaries, that we have enough evidence to say that the loading of, for example, endocrine disruptors PFAS, persistent organic pollutants all forms of, of um, chemical long lasting chemical products.

In general, it is best to assume that the network is filled with malevolent entities that will send in packets designed to have the worst possible effect.
it tells us little about sales of actual ebooks
Or about the broader context for reading. Often strikes me that we still take the “book” concept as a given. Texts come in many forms but we’re stuck with this model of packaging texts by length. Much of literary postmodernism had to do with breaking free of those boundaries on our thinking. But eBooks often reproduce the linearity and boundedness of pre-hypertext “books”. Landow’s book was first published in 1991. What happened in the last 25 years?
