How do memristors work? [Onward implications for Strong AI.]

Memristors are in effect tunable resistors; where a resistive state can be programmed [and changed, so far a very finite number of times]. This means they can store and process information, especially by carrying out weighted-product summations and vector-based matrix array product summations. Such are very powerful physically instantiated mathematical operations. For example, here is […]

My conclusion (so far) on the suggested infinite past, beginningless physical world: not plausible, likely not possible, here’s why

One of the more astonishing points of debate that has come out at UD is that at least some defenders of the evolutionary materialistic view are prepared to argue for or assume as default that we have had a beginningless past for the physical world.  This has come up several times in recent years and […]

Fun with the hyperreal numbers (and with the idea of an infinite actual past)

The hyperreals are an extension of the real number line that brings to bear a reciprocal relationship between the very large and the very small. By so introducing extensions to the real number continuum, it forms a base for an infinitesimals approach to the calculus and makes sense of a lot of the tricks used […]

What about the elusive dream: metallic hydrogen?

With metal-like superionic water already on the table, why not look at the seemingly evasive metallic hydrogen? A year ago, there was a happy announcement (and an article in Science), but doubts have since been entertained; indeed Science issued a correction to the original paper. Science: >>Producing metallic hydrogen has been a great challenge in […]

Why is it that there is discussion of superionic water as being both solid and liquid?

One of the things that struck me in looking at superionic water is how it is so often spoken of as though it were partly liquid and partly solid. I did a spot of reflection, which I am thinking it may help to headline. Where, some of the ideas being brought up will help us […]
