If it weren’t for the Pauli Exclusion Principle, the matter we have in our Universe would behave in an extraordinarily different fashion. The electrons, you see, are examples of fermions. Every electron is fundamentally identical to every other electron in the Universe, with the same charge, mass, lepton number, lepton family number, and intrinsic angular momentum (or spin).
If there were no Pauli Exclusion Principle, there would be no limit to the number of electrons that could fill the ground (lowest-energy) state of an atom. Over time, and at cool enough temperatures, that’s the state that every single electron in the Universe would eventually sink to. The lowest energy orbital — the 1s orbital in each atom — would be the only orbital to contain electrons, and it would contain all of the electrons inherent to every atom.
In essence, existence as we know it would not exist ...
The rise of quantum ...
The central assumption behind his new derivation, presented to the DPG on 14 December 1900, was the supposition, now known as the Planck postulate, that electromagnetic energy could be emitted only in quantized form, in other words, the energy could only be a multiple of an elementary unit:
where h is Planck's constant, also known as Planck's action quantum (introduced already in 1899), and ν is the frequency of the radiation. Note that the elementary units of energy discussed here are represented by hν and not simply by ν. Physicists now call these quanta photons, and a photon of frequency ν will have its own specific and unique energy. The total energy at that frequency is then equal to hν multiplied by the number of photons at that frequency.
Digital also applies to ...
The uncertainty principle states that we cannot know both the position and speed of a particle, such as a photon or electron, with perfect accuracy; the more we nail down the particle's position, the less we know about its speed and vice versa.
At its base level, reality is digital as per the subatomic zoo seen below.

Prescient comes to mind when viewing Peter Finch's epic rant as Howard Beale in Network, one of the truly great films, not only as biting satire but also as an accurate prediction as to what society has become 47 years after this masterpiece was created. Watch the entire film as its take on business, society and the absurdity of the human condition is spot on to the max.

Quantum Mechanics is hard to understand as the subatomic world plays by different rules from the classical as particles are both wave and particle, the former existing when unobserved and the latter, when observed. Now that we know Alice in Wonderland lives, Richard Feynman's radical notion of using diagrams to graphically show how subatomic particles interact would not only change how man viewed quantum mechanics but also how mankind viewed the world.

1801 and 1900, years forever changing how man views reality, were the start points of all things relating to the world of computation. The first was Thomas Young's double slit experiment showing light to be both a wave and particle and in 1900, the introduction of quantum mechanics showing, without question, that existence is digital with analog override. :)
- The meaning of the era of quantum mechanics
- Without quantum mechanics, there would be no computer - modern civilization is quantum civilization.
- Why is quantum mechanics difficult- Even genius physicists such as Richard Feynman and Niels Bohr said it was difficult.
- Quantum mechanics is difficult because it goes against common sense and intuition.
- The first step in understanding quantum mechanics is to understand the quantum. Examine the origin of quantum and its physical meaning.
- One of the backgrounds of the birth of quantum mechanics was the problem of blackbody radiation.
- Examine Max Planck's quantum hypothesis, which established a quantum hypothesis and sowed the seeds of quantum mechanics.

Comin' in on a wing& a prayer, a quote from a WW II bomber pilot, points out, in a roundabout way, the hope AI will not become a danger to mankind because this is all man can do in praying we can control a tech we will never fully understand ... ever.
...with microchips more than 100-thousand times faster than the human brain. We asked Bard to summarize the New Testament. It did, in five seconds and 17 words. We asked for it in Latin--that took another four seconds. Then, we played with a famous six word short story, often attributed to Hemingway.
From the six-word prompt, Bard created a deeply human tale with characters it invented -- including a man whose wife could not conceive and a stranger, grieving after a miscarriage, and longing for closure.
We asked for the story in verse. In five seconds, there was a poem written by a machine with breathtaking insight into the mystery of faith, Bard wrote "she knew her baby's soul would always be alive." The humanity, at superhuman speed, was a shock.

Roll your own. Just type in a few keywords and voila, you are a scientist, chef, architect, whatever as AI does the job for you and you don't have to do the time to become good at something but ... what happens if the power goes off or the AI in question vapor locks. Interesting questions to ask, is it not?
A student at Cardiff University has told the BBC that he used the ChatGPT artificial intelligence natural language processing tool to help him with his coursework and assignments for his degree. The student, whose real name was not disclosed, told the BBC he received first-class grades for essays written using the AI chatbot.
He explained that he averaged a 2:1 on most of his assignments but decided to find out how ChatGPT would compare to another 2,500-word essay of purely his work, both of which he submitted in January. The results were stark.
He received, as expected, a 2:1 for his, but the AI achieved a solid first for its essay. "I didn't copy everything word for word, but I would prompt it with questions that gave me access to information much quicker than usual," the student told the BBC.
A 2.1's not too swift but hey, competency is no longer required. Just key it in and your done, right?

Communication 101 ... Over 45,000 years ago, an inspired cave artist painted a life-size pig in Indonesia. What's interesting about the work is the fact it's possibly the first complete figurative art piece ever created while at the same time, a narrative is in play as the pig in the picture is watching two others involved in a serious altercation.
To whit ...
Measuring 136cm by 54cm (53in by 21in), the Sulawesi warty pig was painted using dark red ochre pigment and has a short crest of upright hair, as well as a pair of horn-like facial warts characteristic of adult males of the species.
In looking at humanity's endless endeavor to communicate, one indirectly sees how language shapes one's view of reality. Many animals have language but man is the only known species possessing the manual dexterity needed to enhance the power of language by creating work extending beyond the confines of the vocal, something readily seen by 8500-year-old written symbols like the ones depicted below.
Most of the signs were separately inscribed on different shells.
From symbols to pictograms
to abstract shapes, the move toward writing evolved ...

All the output seen above were created by individuals, content not designed for mass dissemination prior to the invention of the printing press by Johannes Gutenberg in 1440, the machine that changed the world.

The descendent of Xerox Parc's Alto is largely unknown save for geeks like yours truly as Apple's commercially unsuccessful Lisa was the first computer to put together a viable GUI complete with a mouse, multitasking and network connectivity. :) Because the hardware was so expensive, it flopped but it paved the way to the Mackintosh, the machine that changed how man interacted with digital.
