Disc or disk?

Here’s one that makes me think, “Which is it?”

Actually, it’s an easy one. Before the age of computers there were only discs, and a disc could be any flat circular thing, a vinyl record or pretty much anything which had roughly the same shape. There are disc galaxies in space and disc brakes on cars. Getting more modern, we have CDs (Compact Discs), DVDs (Digital Versatile Discs), both of which are pressed, optically-read discs.

A hard-disk, and any other kind of disk you can put in your computer to store or ‘burn’ your own stuff on, is different and stores data on a magnetic layer. This means that many of them can be used more than once, as the magnetic ‘memory’ can be erased to make room for new stuff. These disks should also be stored more carefully. For example, they should not be kept next to magnets, and as every speaker has a magnet inside it’s not smart to use your woofers and tweeters as ‘bookends’ for your storage disk collection.’

There is no such thing as chaos


I believe, that at any level, there is no such thing as chaos, because the laws of physics would be broken.

It doesn’t matter about what level we are speaking, be it microscopic or astronomical, the laws of physics are the laws of physics. Therefore, there is no chaos. If, for example, a rubber ball is dropped inside a metal sphere, and we are unable to predict how it bounces, we call it chaos. If we are unable to predict how people may react in a given circumstance, we call it chaos. I say there is no such thing.

Our inability to predict how something will react is just that. In other words, we simply do not know enough about the objects in question. We simply do not know everything about the composition of the rubber ball, nor the metal sphere in which it bounces. The matter becomes crystal clear when we talk about people. We can never know what they will do in a given circumstance, we can only estimate average reactions. But still we do not have chaos, just the lack of data. I would appreciate feedback about this 🙂

Is Time Real?


Yes – so what is the problem?

The problem lies with the definition of time. On a day-to-day level, I believe that time is functionally constant and reliable. We can create mechanical and electronic devices to divide time into useful tiny pieces, small enough to measure the minute triangulation differences needed for GPS, large enough to let us know when it’s time to take a tea break. This is time as we need it, to control processes, to know what day it is and to be absolutely sure when an astronomical event will occur, or when Santa will come … read more:
