How Artificial Intelligence is developing

In 1949 Alan Turing proposed an experimental exercise which he called The Imitation Game. It was a test to determine the ability of a machine to participate in a human conversation without being caught as a non human entity. Turing’s experience with the WWII Enigma must have made him aware of the potential of computers. The Imitation Game later became known as the Turing Test.

Many decades ago, it must have been in the seventies, I read an article written by Doctor Max Euwe 1901 – 1981, mathematician, computer scientist, and former chess world champion. Continue reading →

ChatGPT – Arty, facts and initiative – A comment

Comments on ChatGPT – Arty, facts and initiative

The first thought I had after reading Paul’s text was: he should have chosen for the setting “Improve the model for everyone” to True.
Arty could certainly learn from this discussion and the remarks.

The most obvious fact for humans about Gothenburg’s metro is: it isn’t there. For our AI, the metro is just another public transportation arrangement and in its absence, he offers another system that can fulfil the service.
Clearly a matter of interpretation, and Paul is lenient here, no penalty for Arty. Continue reading →

Shor’s Algorithm, the quantum part

A word in advance

Before I sent my previous essay ’Shor’s Algorithm’ to Chief Editor Paul, I asked Arty (ChatGPT) to give it a look especially with regard to readability and tell me if he thinks it’s worth publishing.

My AI friend responded in his usual friendly and positive manner full of praise.

“…well-written!  …managed to strike a great balance between technical detail and accessibility…  , …classical factoring algorithms, as well as the key differences between classical and quantum computing are clearly explained.”

Of course I was happy with these pats on the back, especially from a guy as knowledgable as Arty, but then he came with some critical comments wrapped up in such a casual way that I almost missed them. Continue reading →

Shor’s algorithm

Introduction

Quantum computing is an expression frequently to be found in the news of every self respecting media outlet.
Time and again, yet another breakthrough is described towards the event of becoming fully operational of such a device.
The method of working of a quantum computer (QC) in those reports always comes down to:

  • The QC does not work with bits like all our present computers do, but with qubits.
  • The bits of our familiar classical computers can have the value 0 or 1 but qubits can have both values at the same time. This phenomenon is called superposition.
  • For this reason, a quantum computer reduces today’s supercomputer to an abacus.

It does not seem that this conclusion satisfies the average packet of questions one has about an entirely new technology. Continue reading →

The Foreign language

My wife Wil and I live permanently in France since 2008. We’ve bought our house in 2005, but we were not ready for the final step at that time. Our reluctance was mainly due to the difficulty we had in speaking French.

But in 2008 the ultimate decision was made: France was the place to be, attracted as we were by the beautiful nature, the calm pace of the French countryside and the low-stress attitude of the local people, so we sold our Dutch property.

Does this mean that we overcame the problems we had with the French language? Not by a long shot. Continue reading →

Using AI in non-fiction context, a justification

In his recent essay, “The slippery slope of AI in books” Paul was almost shocked by his publisher’s question “Did you use AI in creating text, images and/or translation in your book?” Of course, he answered with a loud, indignant “NO” to this question.

Then Paul explains to us that he uses Word’s spelling checker and occasionally a grammar checker. But of course, his text as a whole, is his own. Created by him and only him.

That made me wonder, how does this work out for my text with e.g. the contributions to the math section? I am not a book writer as Paul definitely is, but I write nonetheless. And doing so, I try to maintain my personal style. On a very regular base, Paul and I, exchange email messages with a great variety of subjects. We do this for more than 25 years. The writing is in our own style and very recognizable as such.

But this is entirely different from creating a fictional story as storytellers do. Continue reading →

The secrets of RSA encryption

When clicking on the padlock in the address bar of an internet session, a window appears with the message: “Safari uses an encrypted connection with …”. [red. this message may look slightly different for other browsers]

After pressing the buttons ‘Show certificate’ and ‘detail’, a lot more is shown. The typically used security algorithm nowadays at most news sites etc. at the opening session is: public key with elliptic curve.

But for the sites where security really is an issue, e.g. a login session into your bank account or a large online store, RSA is the encryption algorithm. And RSA encryption is the subject of my contribution this time. Continue reading →

P vs NP – A promise fulfilled

P versus NP – An early encounter

My first programming experience was in the early 80’s. I had bought myself a Texas instruments 58-c programmable calculator, and I was curious what could be done with such a device. That turned out to be very modest.
The calculator was capable of 480 program steps but held then zero memories for data storage. Each memory used for data consumed 8 program steps, so with the storage of e.g. 10 integers, the programming space was diminished with 80 steps.
The 58-c’s memory was retained even after switching off the calculator, but before creating another program, memory first had to be erased. Continue reading →

Cultural dilemma – Country vs Religion

One would think it would be easy to describe or define a country. But its definition in Wikipedia leaves room for interpretation that attempts to describe it as ‘…a distinct part of the world, such as a state, nation, or other political entity…’. Notably, the definition of a country does not include ‘a group of people with a certain religion‘ or even ‘a group of people‘. On the other hand, the Wikipedia article does mention religion in any way but for the use of religious symbols, eg. in flags. Continue reading →

Graham’s number

In the 2nd or 3rd grade of my catholic primary school our teacher spoke of stuff like ‘God’
and ‘Heaven’.
“People live in Heaven after their death,” she told us. “All eternity.”
Nobody knew what eternity was, so she had to explain.
“Eternity,” she said, “never ends. “The years go on forever.”
Apparently she saw her pupils struggling with this concept and that made her tell us a
story. Continue reading →

Unexpected turns of events – Short stories

Eef, our resident columnist and contributor of mainly scientific content to this blog, decided it was time to write and publish some short stories collected from his memory under the sub-title ‘Unexpected turns of events‘. It is my pleasure to publish them on this site and bring them to your attention. Eef wrote three stories to date, I have no doubt that more will follow shortly. Continue reading →

The Art of Translation

My all time favorite SF-writer is Jack Vance who died at May 13th 2013 at the age of 96. He wasn’t a follower of the hard science fiction category, there are far more qualified writers for this genre like Larry Niven with his fabulous novel Ringworld, full of hard core science.
In fact Niven had to write a sequel to Ringworld because he wanted to correct a rather stupid technical error in the original story. One which was pointed him out by MIT students. Continue reading →

Mathematical issues

Some remarkable mathematical issues

Although the Dutch newspapers Volkskrant and NRC can be blamed for being too political (D66) biased to be independent as journals ought to be, it must be said that both have excellent science sections.
On an irregular base even topics of mathematical nature have been published.

Of course for a layman’s audience, mathematics lacks the ability of other science disciplines of being easily visualized.
So the topics in these sections were about trivial stuff like the latest calculated decimals of π or some large regions on the number line without any prime number called prime deserts, a newly found Mersenne number, etc.
But that hardly scratches the surface. Continue reading →
