Turing's Cathedral: The Origins of the Digital Universe" *Penguin)






This book was okay. The most terrible thing about it was how the author seemed to jump from one subject to another. He talks about how everything that was computable was attempted to be computed on early computers. George Dyson seems to want to do too much with his limited space in this book. He goes from the problem of Nuclear Weapons development to the creation of digital life.

Although this book is called Turing's Cathedral, it's mostly about John von Neumann and how he went flitting about and making advances in early computer technology. Even if he didn't make the advances himself, von Neumann always found a way to be involved. There's nothing really wrong with this, but, it is slightly misleading. Turing doesn't even come into the picture until the thirteenth chapter, causing me to wonder why it was called this at all. I mean, I guess the point of the entire book is to convey the enormity of Turing's Universal Machine, and the influences it has on the present.

Due to the meandering nature of the author's attention, this book is comparable to Gravity's Rainbow by Thomas Pynchon in some ways. It also made it so I wanted to drop this book numerous times. The author starts out conventionally enough, by talking about 1953 and the first Hydrogen Bomb. He then wanders over to the creation of New Jersey...? But wait no, this matters because New Jersey is where Princeton is, and Princeton is where the IAS (Institute for Advanced Study) is located.So we get to find out that William Penn, the famous Quaker that founded Pennsylvania also had a hand in founding New Jersey.

*Sigh* In any case, this book is not really that well organized, though I suppose it does contain a number of neat old photographs.

In any case, I might read this book again but it would have to be for a pretty good reason.

It has been relaxing listening to Beethoven all day. Yes, I have been listening to all his nine symphonies and now reached the glorious ninth! I have had this 6 CD box set for a while which I had not played. I thought today would be the day.



Now, considering how [livejournal.com profile] desdemonaspace has a broken CD player and considering what she might get -  I have put pictures up of my system and the connected laptop to the HiFi. This might inspire her or at least all you readers can have a peak at my system.



The laptop has a CDROM drive connected as there is no tray on the computer itself. It allows me to play CDS and upload onto the hard drive or burn new ones. As laptop speakers are crap on the left of the PC is a lead is a thick black cable going to my Denon system. It is the one with the silver 3.5 mm plug.

Next to the CD OM is an external hard drive.



So here is my CD player system. A Denon system with a receiver/ amplifier below and a Bush MTT-1 record player on top. That black lead from the computer plugs into an Aux socket on the back of the Denon so all my YouTube videos and streamed TV channels are in glorious sound with the two hefty Denon speakers!

And that is it. A good quality system that packs a lot of sound into a studio abode. The dial on the amp never goes above six because it goes so loud to annoy the neighbours above or next door lol!!

I had a problem with the power lead to my Chromebook the other say. I only found out today when I tried to charge the laptop from the cord. I checked the cord over, changed the section from the power supply unit to the 13 amp plug, but to avail. The green LED light on the power cord transformer is not lighting up. I have ordered a replacement from Amazon for £20 – coming tomorrow – but an unwanted expense.

I spoke to my brother via the phone to see how he is progressing. He says that he is still in pain form the massive surgery he had , and has a concoction of pills to take. He said he felt like a walking pharmacy. The thing he did mention was how weak he felt and it has impacted on his desire to read. Remember he did read 88 books last year. I hope that he will get his strength back,.that he feels better, and able to reignite his love for reading and books.

This week so far I have watched the latest Supergirl and the Flash TV series after the long break from the Xmas period.

Today I did nothing much as I have a busy Saturday and Monday ahead of me.

I am in Spoons at the moment having devoured a pizza/

Sold and posted another CD on Discogs. May this continue.

Roger Penrose "The Emperor's New Mind : Concerning Computers, Minds and the Laws of Physics" (Verso)






Roger Penrose isn't just any old boffin: he is the Emeritus Rouse Ball Professor of Mathematics at Oxford University and has been knighted for his services to Science. The Emperor's New Mind is his attempt to crack that perennial philosophical chestnut, the Consciousness/Artificial Intelligence problem. Penrose's view is that Strong AI is simply wrong and that a computer could never replicate (functionally or actually) what we know as "consciousness".

Originlly published in 1991 this was a long, grueling read. I won't say I clearly understood (or even dimly understood) all this book. At times my eyes glazed over, and my comprehension phased out only to resume later usually after long passages of mathematical symbols ,though the math in this book was relatively simple, and i had encountered Hamiltonians and vector spaces in an O.U. second level pure mathematics course.



It helpd that I'd read other things about artificial intelligence, computers, relativity, cosmology, and quantam physics. By his own admission, Penrose finds it difficult to explain mathematical things verbally and his arguments often go on and on without tying them into the central question of the book - is algorithmically based AI possible? In the end I think they all show to be relevant.

Penrose ventures into widely speculative ground by saying he believes consciousness will be better understood when quantum mechanics and relativity are joined, probably, he believes, by quantum gravity. He makes the startling the proposal that the brain is a quantum computer computing numerous quantum possibilities until gravitational collapsing the quantum wave-function and realizing one quantum reality.

Penrose concludes with some intriguing paradoxes in time perception. Do we really, as certain experiments suggest, experience everything two seconds behind and are limited by a half-second delay before conscious action is realized? Penrose doubts it, but it's intriguing. Penrose isn't afraid to consider philosophical questions which most scientists shy away from and firmly grounds, unlike most philosophers, human behavior and consciousness in the physical world and its laws. Some of Penrose's approaches were different than the usual treatment his topics get, particularly de-emphasizing quantum mechanics' indeterminism and imprecision as others do, but, rather, the precision and predictions the theory does allow.length to explain, and their relevance, without having to get your head around every complicated equation.

I think that some of his theories are enticing, and altogether this was a good read, but perhaps could have benefited from a more decisive outcome. The ending comes an an anti-climax, but getting there is worth the whole trip.

So now that i am down to the one laptop, it is the one that runs on Vista, which i have been reliably informed , it degrades over time. Or to put it another way, slows down as it ages, hence the use of something like C Cleaner to dump out the shit that accumulates.

Still perhaps some time in the New Year an upgrade to Windows 7 would be advisable, plus checking out a RAM upgrade.

Another fine sunny day and hence another trip around the county of Kent. Popped over to Ashford this morning via Faversham.

In Faversham picked up a couple of books from chazzers -

Tom Wolfe “I Am Charlotte Simmons” (Picador)
David Mitchell “Cloud Atlas” (Sceptre)

The latter book I have already read, as it was on my fifty book challenge. One of the best novels I have read this year. I picked it originally from last years Book World Night, but is nice to have it again to read again. I gave the WBN version away.

On the way back from Ashford I stopped in Faversham to nip to the library and bought a couple of withdrawn books from there . I also bought an old 1949 hardback edition of a Charles Dickens book “A Tale of Two Cities” (Oxford University Press).in the alleyway from Preston Street towards the library.

I then took a bus over to Sheerness and picked up three rather literary paperbacks from the Demelza charity shop for a quid in total. Surprised to see such luminous items in a chazzer on the island, until cousin pointed out that people do take holidays there. I doubt much of the inbred residents on Sheppey could make much sense of Margaret Atwood or Milan Kundera for example. Anyway, the three books are -

Margaret Atwood “ Oryx and Crake” (Virago)
Milan Kundera “Immortality” (Faber)
Flann O'Brien “The Third Policeman” (Flamingo).

After dinner, and Eggheads, which clashes with the Meridian news, much to my cousin's annoyance, I retired upstairs to check my emails, add books on to the list and check my sales. Discogs sales have suddenly come back to life , after a few months in the doldrums. I have sold quite a stash of singles, 12” singles and albums recently. I even sold those odd looking AKG headphones for £15 on Ebay..

I also had a large problem with Firefox. It got into some kind of loop and not loading up properly as I entered the internet. In the end I had to delete it and reload it without all my favourites,bookmarks and cookies. Luckily I can remember all my passwords for sites such as Twitter, Facebook, Livejournal, Dreamwidth,Play, Discogs, Paypal etc. It took awhile but now it is fixed. Infact, it is running better and faster, probably due to less bookmarks and toolbars.

I must admit I prefer Firefox to Internet Explorer or Google as my preferred platform.

Watching the Big Bang Theory again on TV, an American comedy that I have grown to love, and in a similar way that Frasier has affected me. It is geeky, clever and funny at the same time. I seem to be watching different seasons of it, depending on the time of the day, and I note that there is already been four seasons of it, so I have quite a bit of catching up to do. I might even buy a couple of seasons with my Play trade funds.

It is weird how people like Brian Cox has made science all sexy again. After his star gazing nights Amazon have reported a five fold increase in the sales of telescopes. Even Jim Al Khalili makes electricity sound fizzing on his recent series on it. I watched the third part of that series tonight on BBC4 whilst cousin was up the pub. Tonight he looked at the development of transistors leading to the microchip and how electricity works in these tiny circuits, and why computers have fans to cool them down to counteract heating up caused by resistance. Resistance drops when things are supercooled and conductivity flows better when resistance is very small, thus the next stage is to try to get superconducting components at room temperature. Once that happens a new age in computing power will emerge, and will be better for the environment , since resistance creates heat.

My battered old laptop will do for now, anyway.
