<p>Sadly, not part of this course, though Lisp and Prolog are very useful for other things.   C's fine for building neural networks from scratch, and you can glue different subsystems together to make anything more complex than that using Python.</p>

<p>Written Chinese stayed the same while the spoken language evolved from the 5th century BC until the 1911 revolution, after which people began writing Chinese the way it's spoken in Beijing.   So there's a sharp dividing line just over 100 years ago; Literary Chinese is still taught in school but without that you'd have trouble understanding it.</p>

<p>Yes, the principle of relativity was known to Newton, but the other idea, that the speed of light is the same in all reference frames, was new, counterintuitive, and what makes special relativity the way it is.</p>

<p>Agreed.<p>General relativity was a completely novel idea.  Einstein took a purely mathematical object (now known as the Einstein tensor), and realized that since its coveriant derivative was zero, it could be equated (apart fron a constant factor) to a conserved physical object, the energy momentum tensor (except for a constant factor).   It didn't just fall out of Riemannian geometry and what was known about physics at the time.<p>Special relativity was the work of several scientists as well as Einstein, but it was also a completely novel idea - just not the idea of one person working alone.<p>I don't know why anyone disputes that people can sometimes come up with completely novel ideas out of the blue.   This is how science moves forward.   It's very easy to look back on a breakthrough and think it looks obvious (because you know the trick that was used), but it's important to remember that the discoverer didn't have the benefit of hindsight that you have.</p>

<p>It depends whether you want your system to handle <i>all</i> of natural language and give answers which are correct <i>most</i> of the time (but it isn't easy to tell when it's wrong), or to handle <i>a limited subset</i> of natural language and either give answers which are demonstrably correct (once it's fully debugged or proven correct), or tells you when it doesn't know the answer.<p>These are two opposing approaches to AI.   Rule induction is somewhere in between - you use training data and it outputs (usually probabilistic) human-readable rules.</p>

    queen(X) :- monarch(X), female(X).
    queen(X) :- wife(Y, X), king(Y).

    monarch(elizabeth).
    female(elizabeth).
    wife(philip, elizabeth).
    monarch(charles).
    male(charles).
    wife(charles, camilla).

    ?- queen(camilla).
    true.

    ?- king(charles).
    true.

    ?- king(philip).
    false.

<p>I had assumed that XWayland is a drop-in replacement fo X11, and will be available indefinitely.<p>I regularly write code which relies on a working X11.   I have written a virtual machine which makes X11 calls to do 2D graphics and event handling, as well as applications which compile to the virtual machine code.   If X11 and now XWayland cease to be available, not only would I have to rewrite large parts of my virtual machine, but also rewrite all the 2D graphics code in applications.   All so that I can stand still when the rug is being pulled from under my feet.   I'm sure there are others in a similar predicament.<p>I may be naive about this, but as X11 just works, and has done for decades, it should require little to no maintenance, so why the need to withdraw it?   I don't expect, or require, any additional functionality.</p>
