Holographic projection using spatial light modulators (SLMs) is unfortunately a dead end due to cost and complexity of manufacturing. There was a Cambridge startup a decade ago called 'light blue optics' (who have a promotional vi

In some places with expensive unreliable public transport, the quickest & cheapest way (a group) into town was by taxi. Minicab to precise. The five minutes away for 45 minutes variety. The cancel without any notice. The sorry I don&#x2

Perhaps consider a steel man instead of a straw one. Socialist institutions that cover natural monopolies save the state money simply by economies of scale. I'll grant not all industry could or should be nationalised but certainly heal

A bit glib but : https://xkcd.com/1227/ I don't doubt we all look at younger people and worry about the future. I'm going to assume it's part of getting older.

Think? Know! Cramming works in the short term due to the nature of mass testing. Any sensible person identifies what they will be judged upon and maximises their effort towards that. Especially if we're in a world of credentialism. Whi

Current peltier chips are barely a few percent efficient, break easily and require high temperature differentials. They're used in stove-top fans and RTGs. The latter should be Sterling engines to be ignorant mind. I don't doubt t

Precisely. Articles such as this, without metastudy to back up spurious claims, are the horoscopes of the modern age! Project your own culture upon it and espouse the 'correct' creed.

Precisely. Due to the pandemic we now know two things in the UK. First that there are 9 times as many homeless as stats claim and second that all people can be housed. This is due to the fact that this was accomplished during the first lock

Radix Positional notation is just one way to represent numbers. A way that is better for arithmetic than arbitrary numerals certainly. However it's important to remember that alternatives give us a comparison. A way of seeing implicit
