The Worse Case Scenario for Gen AI - "Vegetive Electron Microscopy" - Eh?

Spoiler alert .. this post highlights a silly episode in Gen AI (see below, the construction of a bogus term, "vegetive electron microscopy" by AI automated consumption on mass of thousands of documents, because the input process did not expect the document to be formatted in columns): 

Column one is about biology, column two is about physics, by parsing convention the AI sees "a thing/entity" called "vegetive electron microscopy" and pumps it into the LLM and from there is gets used and recommended. Read full article below:

Funny after you spot it, serious when you don't!

Audible Book: Black Holes by Brian Cox and Jeff Foreshaw

Following my son's interest in Physics (I was pretty useless at hands on Science at school and ended up doing Computers instead) I thought I might try and "audible" my way into what makes him so excited about it. The latest book by Brian Cox and his compatriot Jeff Foreshaw seemed as good a place as any to start (see below, "to boldly go" or rather "sit back and listen") : 


Well there is an Elton John song that comes to mind, aka Rocket Man and the line "All the science I don't understand", but I enjoyed the ride and bought a physical copy of teh book to go back to! I may well have to listen again to this one. Thought provoking and often mind blowing!

The Man From The Future - John von Neumann (Audible Books)

I thought I knew something about John von Neumann, but this book amazed my by revealing how little I really knew about him at all. He was the definition of a Polymath .. and  a Nobel one at that, in many fields! So, hand on heart, I can thoroughly recommend this title (see below, I listened too it via Audible, but intend to buy the book too, so I can skim through the chapters again .. I cannot give a higher recommendation than that): 


A tantalising peek at its contents reveals: 

"The smartphones in our pockets and computers like brains. The vagaries of game theory and evolutionary biology. Self-replicating moon bases and nuclear weapons. All bear the fingerprints of one remarkable man: John von Neumann.

Born in Budapest at the turn of the century, von Neumann is one of the most influential scientists to have ever lived. His colleagues believed he had the fastest brain on the planet - bar none. He was instrumental in the Manhattan Project and helped formulate the bedrock of Cold War geopolitics and modern economic theory. He created the first ever programmable digital computer. He prophesied the potential of nanotechnology and, from his deathbed, expounded on the limits of brains and computers - and how they might be overcome."

It is also pitched at the general reader (so I didn't have that Stephen Hawkins Brief History of Time, "What does that mean?" - effect here on me).

Books of Interest

It comes from my early childhood days, I am hooked on the "book habit" (they are magical things) and throughout my life nice people (damn them) keep encouraging me to read, by making very good book recommendations. If that were not bad enough, some authors (damn them twice over) are not just content to write one interesting book, but they then go and have the cheek to write another or more! Imagine this crazy situation, what am I to do? (see below, this "book" made me want to read more about the sciences, Ben Miller being a well known TV comedian who kept a dark, secret [as in, he liked science]!): 


I am pretty sure it is a form of mind control (see below, from sensible science mysterious to looking for alien life - then a friend recommended a book that says it is about structure problem solving - but it has a hidden use, designing wargames): 


The question is do I push for another bookshelf or try and squeeze them into my existing ones, or pile them discreetly on the floor, until they become a tripping hazard? Your recommendations greatly received!

Yes, but WHY? It is those "Big Bang" Style Physicists again!

I had the pleasure of walking round some University Physics Departments late last year with a fresh-faced prospective undergraduate student (my eldest son) who is going through the crucible of the A-Levels bless him. Most of the stuff the staff were talking about went well over my head so I ended up drinking free coffee, eating free cake, then watching the walls and reading the posters as my son toured "the facilities" (see below, one poster that particularly caught my eye): 


Yes, ok .. but "why" would you want to do that in the first place? Plus what about the frog, his-her-its  participation and agency in this? I have ethical questions! You can also bet that the reported result was not in the original remit of the research .. methinks the beastie literally hopped into what it thought was probably a nice little hole to hide in from predators! Ha .. and it ended up floating away! 

Did it live?

Nikola Tesla: Audiobook

I found this book both interesting and disturbing. To me Tesla was an enigmatic background figure I knew very little about, bar references to photographs of strange sparking coils [plus the crazy one of fields of planted 'lit' light bulbs] and his name being assigned to a unit of scientific measurement (for magnetic fields). The fact Elon Musk named a car after him is an interesting footnote. The disturbing aspect to me was drawn from the time period (mid-nineteenth century to mid-twentieth century) in which he lived and the attitudes that permeated societies, the scandalous battles of patents and sharp business practices (see below, the Serbian genius, the father of the polyphase AC current and whose full impact on science is still shrouded in mystery [the mystery of the missing Tesla papers]): 
 


A brilliant original inventor who could make remarkable prototypes but who again as often as not, could not bring a viable product to market (but others used his technology to do so and the consequently costly litigation of patent law battles ensues [Marconi implementing something]). Who knows how history will truly judge Tesla, were it for not the US dropping their suite against Marconi because of the first world world war his precedence might have been. Dying as a recluse, "all" were keen to see the material he was working on in his latter days.

Space Website: Physics or Orbital Space Engagements

Not quite Star Wars for sure!

I would NEVER have believed the Physics of this was possible or the Failure to spot it!

I think this is an example of is called "Deep Simplicity!" You let the Americans find the sophisticated stuff you put in the building but sneak in the real thing Trojan horse style through the front gate with a smile!
