A conceptual model for human image recognition: combining passive memory with active imagination

When I was in college (in the ’80s) the question why humans outperform computers in image recognition already was receiving some attention. At the time an idea came to me, and it still seems relevant enough to write down. No … Continue reading

Collective Intelligence seems a bigger threat than Artificial Intelligence

Recently both Stephen Hawking and Bill Gates have voiced their concern over Artificial Intelligence (AI), warning that AI could possibly become a threat to humanity in the future. This prompts me to (finally) write down some thoughts on Collective Intelligence … Continue reading

The arrow of time (4): entropy and reversibility, pictured in designs

So…I do not see any convincing answers in physics to the basic question of `what is time?’. To wrap up this complicated subject for now, I will show some half-designs for the IMAPP symposium (which I did not elaborate on … Continue reading

The arrow of time (3): what is it, actually?

No, but honestly: what is meant by the term `the arrow of time’? I cannot get my head around it, unfortunately. This seemingly puts me in an unenviable minority position, enhanced by my obvious ignorance of relevant theories in modern … Continue reading

The arrow of time (2): Francesco del Cossa

[continued from the previous post:]   (click for enlargement)   The Arrow of Time (almost final design) The basis of the design is formed by a detail from the fresco `Allegory of March: the triumph of Minerva’ by Francesco del … Continue reading

The arrow of time (1)

Three years ago I was asked to design a poster for the symposium `The Arrow of Time’, organized by IMAPP (Institute for Mathematics, Astrophysics and Particle Physics). I would like to show the final design that I made, and also … Continue reading

All bets are off, to disprove the strong physical Church-Turing Thesis (foundations of probability, digital physics and Laplacian determinism 3)

(continued from previous post) Let H0 be the hypothesis: `the real world is non-computable’ (popularly speaking, see previous post), and H1 be PCTT+ (also see the previous post). For comparison we introduce the hypothesis H2: `the real world produces only … Continue reading

An experiment to (dis)prove the strong physical Church-Turing Thesis (foundations of probability, digital physics and Laplacian determinism 2)

There seems to be a pervasive role of `information’ in probability, entropy and hence in physics. But the precise nature of this role escapes me, I’m afraid. I may have said before somewhere in this thread that I do not … Continue reading

Foundations of probability, digital physics and Laplacian determinism

In this thread of posts from 2012, the possibility of drawing a natural number at random was discussed. In the previous post I rediscussed an entropy-related solution giving relative chances. This solution also explains Benford’s law. In the 2012 thread, … Continue reading

An entropy-related derivation of Benford’s law

In this thread of posts from 2012, the possibility of drawing a natural number at random was discussed. A solution offering relative chances was given, and stated to be in accordance with Benford’s law. Then, due to unforeseen circumstances, the … Continue reading
