From Wikipedia, the free encyclopedia

Singularity may refer to any of a variety of concepts.

Mathematical singularity, a point at which a given mathematical object is not defined

In complex analysis:
Essential singularity, a singularity near which a function exhibits extreme behavior
Isolated singularity, a mathematical singularity that has no other singularities close to it
Movable singularity, a concept in singularity theory
Removable singularity, a point at which a function is not defined but at which it can be so defined that it is continuous at the singularity

In algebraic geometry:
Singular point of an algebraic variety, a point where an algebraic variety is not locally flat
Rational singularity, a concept in singularity theory
Singularity theory, which deals with these concepts

Gravitational singularity, a point in spacetime in which gravitational forces cause matter to have an infinite density and zero volume
Mechanical singularity, a position or configuration of a mechanism or a machine where the subsequent behaviour cannot be predicted
Prandtl-Glauert singularity, the point at which a sudden drop in air pressure occurs
Singularity (climate), a weather phenomenon associated with a specific calendar date
Technological singularity, a theoretical point in the development of a technological civilization
Van Hove singularity in the density of states of a material

Singularity is an interesting concept in a universe where things are
generally self-similar and continuous (as part of a continuum).
Singularities also happen in one's life. A birth, a tragic loss, a very
close call with death, a brush with mental illness, something or an event that changes the rules for ever.

Intermediate Ends Of The World

When I die it will be the end of the world as far as I'm concerned - and since I don't believe I'm the habitat of something "higher" than me, that'll be that. For most of us and most of our descendants' descendants, it will be the same, a private end of the world.

There is also a probability that the human civilization will exterminate itself, and that catastrophic change might happen so relatively quickly that people will be witness to it. That's another possible intermediate end of the known civilized world.

Then there's the chance an asteroid hits our planet to smithereens, in which case we would all live through an end of the earthly world. And if none of the above occur, the following clip illustrates what's most likely to happen as far as a galactic end of the world.

Then later, something might endanger our local cluster of galaxies either ripping the fabric of the universe, or having it's space filled with neighboring clusters, as the heading picture (educated simulation) of clusters of clusters suggests.

An ultimate End Of The World? of course! One day - a freeze, a crunch, no one is yet certain. But all seems to indicate that fatal entropy will win. Until then let's just forget about the many religious justice scare tactics and expected judgement days, and relax. Let's consider instead and keep busy with our own peremptionality.

Making or doing art

A fabricated object or behavior loaded with intent.

Intent to share, communicate, intervene, interfere, entertain or otherwise impact fellow humans.

For the artist it is a statement. The object or performance is infused with his intent. The viewer is touched and reacts, feels and interpret its effects and forget, remembers or integrates the experience. Not much need be done for art to be made. In the above picture (taken by somenone else) I just added some tint and texture and an english word. Other artists will put an ordinary object out of context or under a different light. Or highlight a pattern or behave in special ways... Art can be simple or flourish in sophisticated intricacies and technical achievements. And it is something we human animals do to each other to enjoy or enlighten ourselves on our ephemeral condition. And we are now at a point in our evolution where art has become vital.

Basic Cosmological Knowledge

This is the basic knowledge about the universe that should underlie all theological and philosophical speculations and assumptions. Please push the Play button.

And this explains the method by which knowledge such as the above is acquired, verified, built upon.

The Table's End

Where does the table effectively end?

Infinitesimally, atoms of solid wood turn into flowing atoms of air while from my point of view, there is a surface of solid wood. But is there?

We know that however polished that surface is, if you look close enough, it is rough and ragged. And at the atomic level, there are places that are wood and places that are not. There's even a level of uncertainty on what is part of the table and what, is part of the room's air.

We also know that this solid wood surface is constantly being modified by traveling molecules and electromagnetic bombardments and other contacts with solid objects. And that atoms and molecules of the table are constantly let loose from the solid. We also know that some particles can even go through that solid wood table.

What's interesting it that there is no exact frontier between the table and the air, even though from my point of view, there seems to be one. Then my assuming that there is a trustable interface between solid and gaseous would be "close enough for rock and roll".

So for most of us, most of the time, approximate assumptions are more than enough for functional living. If it wasn't for challenges and curiosity.
