What makes us believe we can represent an analog universe with digital representations? We can only know the radius of a circle or it's circumference with precision because Pi is an approximation.

Yes. So what's wrong with that?We can only know the radius of a circle or it's circumference with precision because Pi is an approximation.

Pi is exact. Any real figure is only approximately a circle.GregoryC said:What makes us believe we can represent an analog universe with digital representations? We can only know the radius of a circle or it's circumference with precision because Pi is an approximation.

Actually they do, the chemical aspect is analog, and the patterns can be argued for digital. But yeah like you said, not in this thread's current location.Drakkith said:I believe neurons have both analog and digital "properties", but that's a topic for the biology forum, not this thread.
Analog refers to a continuous signal or data that is represented by physical quantities, such as voltage or sound waves. Digital, on the other hand, refers to discrete signals or data that is represented by numbers or symbols.
In terms of capturing and reproducing information, digital is considered to be more accurate than analog. This is because digital representations are not subject to noise or interference, which can affect analog signals.
Yes, analog and digital can coexist and often do in many modern technologies. For example, a digital camera may capture images using a digital sensor, but the images are stored in an analog format on a film negative.
Digital representations use mathematical algorithms to convert analog signals into discrete numerical values. This allows for precise measurement and analysis of analog phenomena in the physical world.
Digital has several advantages over analog, including better accuracy, easier manipulation and processing of data, and the ability to store and transmit large amounts of information quickly and efficiently.
