Dragon's Egg by Robert Forward - a review

Sci-fi isn't usually my thing, I tend to get wound up by ridiculous names of endless two dimensional characters and mind-boilingly bad science, though clearly there are some major exceptions to this generalization.

I no longer remember where I came across the shining review of Robert Forward's Dragon's egg (possibly from some of Douglas Hofstadter's writing) but the idea hooked me immediately and despite the fact that it's no longer in print I managed to get hold of a copy through the wonderful AbeBooks.

The concept is based on a simple question: Is it possible to have life in conditions where there is normally little complexity? The majority of Dragon's egg takes place on the surface of a pulsar, where gravity is 67 billion times stronger than that on earth and there is no 'chemistry' as we know it. In this world the complexity comes from a chemistry where the leading force is the strong nuclear force and combined with the fast spin of the star, when life evolves it evolves at a rate a million times faster than that on Earth.

The story itself is rather wonderful (we see intelligent life, albeit far smaller than on earth, evolve from the prebiotic soup of the thin crust of white dwarf matter and accelerate past that on Earth) but what is even more astounding is the level of physics that went into the writing of the story. Starquarks, giant magnetic fields, the interplay between the beings and their landscape and the exchange with the humans who come to visit them all make for an incredibly detailed and well thought-out novel on a fascinating subject stemming from an important question. The book includes an encyclopedia of the biology, geology and history of the star and its inhabitants which adds to the depth of the story.

The writing is not going to blow you away, but for sci-fi it's very readable and is definitely going to get you thinking. As this is the five year anniversary of the observation of one of the most monumental events in our galaxy on a star not unlike that which the book is based on, see if you can get yourself a copy and think about what else may be out there.

The Beijing of Possibilities - A review

I met Jonathan Tel back in Beijing around three years ago when he came to research his latest book. He contacted me as an expat to discuss some of my views on life in the city and we met for a meal in a Hunan restaurant on the North side of Haouhai lake.We spent a few enjoyable hours talking string theory, writing, travel and food (in a past incarnation Jonathan had been heading the way of the theoretical physicist).

Shortly after this I read Freud's Alphabet, Jonathan's second novel, which I now realise never received the full review it deserved. It's a dream-like look at the last days of Freud's life and the playful language alters as Freud's state becomes ever more influenced by the cocktail of cancer and morphine. The book, split into 26 alphabetically ordered vistas is well worth a read, both for the word play and for the slightly Joycian stream of unconsciousness which takes you through the book via a series of chaotic passages in one inevitable direction.

But that's not what this review is about. I was lucky enough to get a copy of The Beijing of Possibilities a few weeks ago and the fact that it has taken me such a long time to write this is a sorry reflection of life over the last few months.

-----

Beijing is a land of unfinished stories. Every time you leave the flat you will see some loose thread of a scene which has a mystery behind it: the man wandering around in his pyjamas, the sullen girl at the bus-stop with empty eyes, the tattooed businessmen arguing at the table next to you, the Beijing goths in the I love kitty car. Everything has a back-story, but you are always left wandering.

When I met Jonathan back in Houhai he was researching the iceberg beneath the water that filled in the rest of these tales.The Beijing of possibilities is a book of short stories about the depth of Beijing life, mixed helplessly between ancient and modern, these are the windows into the split second pieces of action you see every day on the streets of any big city, but in Beijing more than any you know that the truth is much more interesting than what your imagination can muster.

The stories combine these events with ancient Chinese folktales to give a real sense of the Beijing which people who don't know the city well have real trouble understanding - the metropolis simply has too many layers of history, culture, pain and change to get a real idea of the diversity and complexity of life there, from the migrant workers to the modern couple living their dreams in a small Haidian apartment, from the factory worker to the opera librettist, Jonathan has captured the strange mix of brilliant colour with smudges of black and white without which it is impossible to think of Beijing.

In addition to the stories themselves, there is a more subtle play. Milan Kundera likes to put himself firmly in the middle of his stories, and sometimes you don't know on what level the narrator is with you as novel and commentary intertwine. Jonathan Tel pulls the opposite trick and sits in the shadows of his book making the pen seem to move without an author, and I have to say that I enjoyed this a lot. It influences the book only subtly but adds to it Jonathan's own style and character.

This book of short stories can be found at Amazon UK and Amazon US and I'd highly recommend it for anyone wants to see behind the door into the Beijing of possibilites.

On the shoulders of...

I have a little while before I head off through the currently lashing rain to do my now routine few hours in the library, which I'm currently thoroughly enjoying, and certainly getting a decent amount done in the wee hours of the morning.

I wanted to post a quotation, which made me chuckle, which I came across last weekend while reading Steven Pinker's book 'The stuff of thought' (authors@Google talk on this book),  a study on how we can learn a great deal about the way we think through the way we speak and pick up language. I've never been disappointed by a Pinker book yet, and generally close the last page with a thoroughly altered perception of the world from that which I started with.

In a chapter focusing on the inateness of language, Pinker choses to discuss the extreme possibilites, starting with the ideas of Jerry Fodor, who believes that we are born with around 50,000 concepts which are pinned with their corresponding vocabulary when we come across the words which fit the concept. Though Pinker clearly has some fondness for Jerry, he does dress him up as the joker and discusses the straw man concept specifically to build him up and knock him down. Pinker clearly isn't alone in his dismissal of Jerry's ideas. The quotation below, more humorous than insightful into the world of neurolinguistics, comes from Dan Dennet (see here for a great TED talk on dangerous memes), whose writing I enjoy very much:

Most philosophers are like old beds: you jump on them and sink deep into qualifications, revisions, addenda. But Fodor is like a trampoline: you jump on him and he springs back, presenting claims twice as trenchant and outrageous. If some of us can see further, it's from jumping on Jerry.

Incidentally, the argument and mockery is not unidirectional, with Fodor arguing against Dennet's very machinery of philosophy - see Fodor's wikipedia article for details.

On a similar note, after being rather disappointed with Maryanne Wolfe's first couple of chapters of Proust and the Squid: The story and science of the reading brain I was extremely pleased that it picked up considerably and though there were occasionally too many unnecessary details on the neurophysiology behind her ideas, the sections on dyslexia, especially with respect to the condition in different languages, was fascinating.

Anyway, about time for me to brave the weather, plenty of papers to read through tonight...

Encounters at the end of the world

Once again Cine Europa comes to Santiago this month, and I hope to make it to more than one film, which was my paltry effort last year.

There are 10-20 films showing every day, from around the world and from many genres and I went yesterday to see the latest film by Werner Herzog, "Encounters at the end of the world" - Herzog's continuing quest to discover something about what makes us human by searching for the extremes that we put ourselves through.

I find watching his films, both documentary and fictional, a rather strange experience.  Herzog's films, more than any other director I know, are more about Herzog than about his subject. One doesn't go to see Encounters at the End of the World to discover a true picture of life at the Antarctic science base, but to hear Herzog's personal thoughts on the peculiarities he sees in such life. The editing and manipulation of the characters is clear and occasionally over the top, making the eccentricities the overriding feature of every character. As long as you go in with your critical senses alert you will be able to experience the world through the eyes of a very accomplished director and this is no bad thing in itself.

If you want a film which shows the beauty of the Antarctic, then there are dozens of more appropriate documentaries out there, but this doesn't detract from the occasional spine-tingling shot, or thought provoking piece of dialogue that is offered. Despite the beauty however, the films overall message is one of warning and pessimism, with little hope for salvation, The end of the world simultaneously taking on multiple meanings.

Through the pessimism however, appears a message, which though my materialist eyes gives a positive spin to the overall theme. Quoting Alan Watts, the forklift truck driver states that:

We are the witness through which the universe becomes conscious of its own glory.

and although Watts' ideas are given a religious overtone, exactly the same can be said in purely physical terms: our minds, being part of the universe, give the universe and not us alone a self-consiousness with which to study itself. This is something that I feel strongly, and this fact alone is enough for me to want to understand the universe more and more, in its huge complexity stemming from such simple principles - principles which we may or may not be alone in trying to understand.

just a thought...

The Adventures of the Pisco Kid - A Review

I met Michael Standaert, after reading on his blog that he'd written a novel, was in Beijing and was looking for people to review it. I e-mailed him to say that I was interested, having read a review on another site which looked intriguing.

We met up for the launch party of the book which was a small but enjoyable affair at Hutong Pizza along with a few other friends. After that we met up in Beijing regularly, though not frequently enough and I was sad to say goodbye to him, his wife and all the other friends I met through them, I'm looking forward to catching up with them next time I'm back in Beijing. As a parting gift I received a signed copy of his book, and one of the few to have made its way to China.

Of late, the only time for reading has been between about 1.30 and 2 in the morning when I'm trying to slow down before sleep. However reading The Adventures of the Pisco Kid, is not an exercise in slowing down.

If Kafka were to have gone to Las Vegas on a drugs bender, or Hunter S Thompson had tried to rework The Trial, they may have come up with something along the lines of The Adventures of the Pisco Kid. Surreal, satirical, moody, funny, chaotic and extremely eloquent, it's rather difficult to write a review about this book and not look like I'm simply writing a good review for a friend. However, I promise this isn't the case!

I started reading this with moderate to high expectations. Michael has been a journalist for the LA Times, has written for the Huffington Post and is now an editor for a Beijing magazine so I knew he knew what he was doing. However, the difference between a writer who can string a story along and someone who can play with words as Michael does is a huge one. The characters in the book have the wonderful caricature of those in A Confederacy of Dunces, the flaws in the characters melt off the page in a slimy mass of neurosis and physical repugnance, bringing the whole thing to life in a vast, Daliesque psychedelia.

We follow the adventures of Pisco, a boy found in the bull-rushes, adopted and bought up by a Jamaican, heavily Christian woman, filling him with skepticism and bitterness having set him up to be a modern-day Messiah. A rat-catcher, and rock band reject, Pisco gets ever deeper into a crazy world where he seems to have no say in how his is pin-balled from one calamity to another. Perhaps if Cervantes had lived in the '60s he would have given us something similar.

The language of the book flows fantastically, and although the author whom I write about most frequently (Steinbeck) is a minimalist when it comes to fancy word play, I'm very happy to read a book where the words and phrases have been picked carefully to develop a rich atmosphere. This is exactly what happens here, and I love it!

The story is punctuated by lyrics from the band that Pisco left before they became big, along with sayings from Navajo and Inuit and the words of Soft Cell and David Bowie. This only adds to the surrealism.

Michael would never really tell me what the book was about, and I shall not do so either, but would recommend this to anyone who is a fan of very witty and well crafted writing, and doesn't mind being taken on a surreal journey which makes the writing of Marquez or Bulgakov seem pretty plausible! I namedrop here simply because I was reminded throughout of the different styles of many of my favourite authors.

I have a good number of people in mind who will like this, though it's not for the faint-hearted reader. Let yourself be taken on the trip however and you'll be very pleased you did. I look forward to reading Michael's next novel, whenever that comes along.

Michael has written a previous non-fiction book "Skipping Towards Armageddon: The Politics and Propaganda of the Left Behind Novels and the LaHaye Empire" which looks similarly intriguing if rather more scary.

Reflections, endings and beginnings

This blog is two years old today, and I believe this is the 369th post.

-----------

Work finally calmed down late on Tuesday evening. Over 40 hours of intensive calculation in 3 days left me utterly exhausted. I've never needed to work with quite such fevered intensity as this. I've never been a crammer, exams at undergraduate level were a relatively relaxed affair in terms of timing as the revision was usually well planned. So, the task of pulling a series of very late-nights and early mornings was not something I envisioned enjoying. However, the hours did go between complete fatigue and a strange, work fueled euphoria which was actually rather empowering at times.

Yesterday I was too drained to do anything of any use, so I had a relaxed day in a cafe and then went to see Bergman's Wild Strawberries at D22. An early road trip movie, concerning the realisition of an elderly man about the path his life has taken and what he has lost, both physically an emotionally through the years. It's a reflection not just of the individual, but a look at how we sometimes ignore the mirror of those around us, forming our own crooked picture of the way we appear, and our own moral absolutes. This is perfect Bergman material and well worth a watch. Having seen Through a Glass Darkly, earlier in the year I now realise how adept Bergman was at capturing troubled emotions through simple images - sometimes cliched, but always powerful.

-------------

I wanted to add an extra note about the Kabuki, which I watched twice last week. I'd been pondering the use of the onnagata, the men who specialise in playing women's roles (there are no women in kabuki performances, though there used to be).

As I watched the second performance on Wednesday evening I wondered what it was about a 76 year old man (Kabuki legend Nakamura Senjaki III) playing the role of a young woman, a teenager, dancing on stage, that was so captivating to watch. This sounds strange, I'm sure, but in fact it comes off as absolutely natural and beautiful to watch.

I was trying to work out why one would have men playing female roles, other than through simple discrimination, but I think I have a clue now, after my fourth viewing of Kabuki. The vision of a man playing a woman's role is an entirely de-sexualised one. There is no thought of the player on stage having anything to do with sexual allure, as it might do if it were a beautiful woman playing the role. What you are left with is a neutered form but still retaining all the elegance and grace which may have been masked by any erotic distractions. The stripping of one aspect of attraction to reveal in much more clear contrast another. It may sound strange, but it really is fantastic to watch.

OK, I think that's probably my input on Kabuki for now, but I'm sure it will crop up again in the future.

-----------

I'm still feeling pretty drained but have plenty of work to be getting on with now. Just three full weeks left in Beijing is a fairly terrifying thought - two years have gone very very quickly - thoughts of Bergman resurface!

Space race

Things are just a bit crazy at the moment and I've little time to blog, consequently there are many things I'd like to blog about but have no time. I'm still thoroughly enjoying the lectures at the complex systems summer school particularly those this week by James Glazier on computational modelling of embryonic development. Ideas of cellular automata are racing around and I'd love time to play, but current research won't allow. Still, it's great to get some perspective on such diverse fields.

I was going to give a full review of Transformers but I'm afraid it doesn't deserve such time or effort. There are some fun effects but most of the fighting between big robots was so fast that it was all a blur (perhaps I'm just getting too old). Anyway, the robot sentiments were cringe worthy as were the mistakes regarding the Beagle 2 mission to Mars, the two lead human actors and...well, that's enough for me not to have enjoyed any more than the first 20 minutes or so. Every time it was mentioned that China may have been to blame for the strange goings on the sound was turned off which did amuse me but that was perhaps the biggest smile I got from the whole thing.

Anyway, I noticed this today which is worth a look, a set of photographs of humans in funny clothes orbiting the Earth. Some stunning views of true isolation, though with Big Brother - if not Mother - Earth looming behind, the perspective is a strange one.

I continue to share the blog and news stories of note every day in the widget at the top left of the screen so keep checking back for stories about science, China, travel, food and more when you are looking for a quick bite of something interesting.

Kubrick continues

Watching Dr Strangelove in a bar in Beijing last night was one of those very special evenings. The twists of satire and irony will stay with me for a long time.

Next week:
Wednesday - 2001 A Space Odyssey
Thursday - A Clockwork Orange

Some interesting looking music on over the next couple of days, too.

I saw Elliott Sharp at D22 a couple of months back and promised to write a review. It's been bugging me ever since because, to be honest, I still don't know what I thought. I enjoy experimental music on the whole, the creative electricity of it can be exciting and the dynamics of the musicians is always fascinating to watch. I spent most of the Elliott Sharp concert with a big grin on my face. I enjoyed it, without a doubt, but I don't know whether I was smiling because of the genius of it or the chaotic self-delusion.
Elliott Sharp
It was noise, there's no other way to describe it. It was disharmonies on guitar caused by random bits of metal grating against strings. It was flutes straight out of Star Wars warbling in different rhythms and different keys (there were no keys) with tuba accompaniment. It was expressions of deepest concentration making music that clashed in ways unimaginable before the evening.

A few people walked out within the first minute. Many stayed and enjoyed it, but I'm not sure what they, or at least I enjoyed. It was, without a doubt fun, and perhaps that's enough. Maybe I just don't understand the depths of musicality which went into it. It took explanation from educated friends and a lot of listening to appreciate a live jazz concert, which I do now, hugely. I can see the dynamics of the musicians as the tune is juggled and manipulated and I love the journey you can be taken on if you follow where they're going. I don't know if I need to know more about where Elliott Sharp was taking us or if I just need some chemical additives to fully appreciate his music. I'd almost certainly see him again because, as I said, it was a lot of fun to listen to and watch.

If anyone else is an aficionado of this sort of experimental music then please tell me what I should be listening for. If you think this is absolutely emperor's new clothes played loud, then I'd like to know your opinion, too.

In a random aside I was highly amused to hear about the klezmer-metal fusion band: Black Shabbat. This I've gotta hear. (from Charmaine X, a creative, amusing Beijing blog I recently stumbled upon).

Linear, or otherwise

I've just presented a blackboard talk to the students on 'The linear confinement problem in AdS/QCD', a topic which I'm particularly interested in studying more myself. I spoke about the papers by Karch et al. 'Linear confinement and AdS/QCD', Csaki and Reece 'Towards a systematic holographic QCD - a braneless approach' and Shifman 'Highly Excited Hadrons in QCD and Beyond', all of which are clear and inspiring for future research.

I've rather given up on the summer school, which was either too elementary or a little too hand wavy, or just too intensive on subjects I have only a passing interest in (4+ hours in one day on CP violation from the B-meson sector is more than I can take). There's talk on several Beyond the standard model conferences in the far West of China and down in Yunnan which would be lovely to go to but they're not quite in my area. I'm keeping an eye out for a good cosmology conference, before the KITPC program which starts in September.

Cosmologists, string theorists and string cosmologists should all come to China for this program!

----------------

After completing most of the preparations for my talk yesterday I headed over to D22, a local bar with an eclectic mix of people, music and events, to watch one of their movies. Having seen clips on TV various times I was keen to see The General from 1927 with Buster Keaton. It's a beautiful film, dated and cliched but Keaton is such an incredible physical actor that everything else apart from his balletic movements and amazing expression are rather overshadowed. Slap-stick, especially of the modern variety doesn't do it for me, but Keaton is so seamless and so expressive that it's a joy to watch.

Looking at still photos of Keaton it's a strange contrast to the expression that come from his movements and if anyone knows a good biography of him I would be intrigued to know why this contradiction is so vast.

----------

Having met him in person a little while ago, I had Jonathan Tel's 'Freud's Alphabet' shipped to me, courtesy of my sister, from England. This is a fictional account, based on the true story of Freud's last few weeks spent in London with terminal cancer. The book is split into chapters labeled alphabetically with Freudian symbols and the book becomes increasingly dreamlike and non-linear as Freud drifts in and out of his morphine haze. Tel's turn of phrase is playful and powerful in equal measure and as long as you don't require linearity and clarity in your stories this book is an interesting journey into dreams, metaphor and the subconscious. Well worth a read.

This links in to the Mario Vargas Llosa book I read while in Japan on the subject of a Storyteller in a Peruvian tribe, which is equally dreamlike, non-linear and imaginatively written. It's been too long since I read it to give it an in depth review but Llosa's story telling, both from his own narrative style and that conjured up for the storyteller's tales of a magical reality weave into each other naturally and give an eloquent picture of an ancient art.

I'm reading another Steinbeck now and enjoying this one as much as ever...expect a review soon.

Royal Society science book shortlist

From the big questions of cosmology through headline making scientific findings, personal journeys in discovering about disease to history-through-science and science-through-history, biography, the brain and the anthropic principle, there's a good range of subjects in this years Royal Society short list of the best popular science books. Of the wide ranging subjects I'm most taken with the Erik Kandel's 'In search of memory', but most of them look enjoyable.

Unparticle physics

I only stumbled across Howard Georgi's latest work when his paper "Another odd thing about unparticle physics" appeared on the Arxiv today. Clearly there was a first odd thing to know about unparticle physics, which leads the reader to "Unparticle physics". This is a very short paper with some fascinating commentary on a possible, previously unremarked scenario for LHC phenomenology (unremarked as far as I'm aware).

The idea is to have a non-trivial scale invariant sector, at least with an IR fixed point, and see how the coupling between the normal particle sector and the scale invariant sector, using effective field theory techniques, effects the low energy physics. The strange terminology is used because in a scale invariant theory the quantum mechanical treatment of particles doesn't make sense and Georgi names the 'stuff' 'unparticles'. The question he tackles in the first paper is what signals one would see in the accelerator if there is a coupling between unparticles and particles. The answer is that although the theory may be highly non-linear, the conformal nature means that the correlation functions can be understood simply through the scaling behavior of the unparticle operators.

Depending on the scaling dimension of the 'stuff' the signature gives a different decay width of regular particles as a function of energy. This very specific signature would be quite clear, giving signals of missing energy at particle accelerators, in a different form from SUSY or large extra dimensions.

The paper is short and clear and gives a hint that there's lots of interesting, easy phenomenology to extract from this strange but not necessarily crazy model. Two new papers today follow this although in the conclusions of the latter paper it seems that the signals from the LHC would not be so clear.

The Thinking Blogger Awards

I return to this polluted, noisy orgy of people and concrete which is 'The Jing' (So good they only named half of it), and though the smell of the smog-filled air crept into the plane as we landed and the jack-hammers greeted us as we left the airport, it does feel like home, and that's pretty good.

I have all the detritus of a long trip to clear up and mounds of dust which have crept through the gaps in the door frame to hide, but that's fine because having managed 5 hours sleep in 3 days I need a bit of catch-up.

On arriving back into the office this afternoon I was greeted with 100+ blog posts to sift through in the feed reader, including a very pleasing nomination from Retrospectacle.

The Thinking Blogger award means that I get to nominate 5 blogs which I deem to fit the title - I also get to show the badge of my pleasingly geeky status:
A bit of fun, but it's nice to know that the random mix of thoughts which I lay down here in no particular order are appreciated.

Anyway, so, my nominations for the award go to:

  • Flip Tomato - An American Physics Student in England. As a part III student at Cambridge he's recently been posting a great mixture of expository writing on physics and his ideas and tips for how one can make the high energy physics community a better and more efficient place to work(not that it's not in many ways already).
  • My personal bias is for blogs which have an eclectic mix of topics and not simply science. This helps to show the wider world that while we love what we do, many physicists have a wide range of interests and can be pretty well-adjusted people - I'm sure I've met some, anyway. Backreaction has some of the best sets of introductions and overviews of topics which I've read in any blogs and mixes this with a bit of art, a bit of social commentary and a bit of, erm, physics rap.
  • I mentioned this as a newfound blog a couple of posts ago - Khymos mixes my love for food and science in excellently balanced proportions in his site dedicated to the world of molecular gastronomy.
  • There are a huge number of expat blogs from China. I tend to stay away from a lot of them which simply expound on how stupid the Chinese are and how country-X is better. It's very tiring very quickly - sure, everyone has their particular quibbles with life out here but generally nobody is forcing us to stay in this strange land and usually the arguments about the ignorance of the Chinese are cheap, generalised shots to make the other expats laugh. The Weifang Radish provides a more level-headed commentary of life out here though includes the politics which I usually shy away from.
  • There are many blog giants out there, some of whom I respect greatly and some of whom I enjoy reading, if only to get aggravated. However, one of them stands out for me as an exceptional mix of cutting edge mathematical physics and very good introductions to a whole range of subjects. In fact the title 'intelligent blog' may be debated simply because the site, starting as a proto-blog has a large range of formats within it. As an undergraduate I learnt many things from John Baez's site and was prompted to go and read lots of excellent books, having had a taster for various topics. Both the diary and this week's finds are blog-like areas of the site which frequently contain a lot of fascinating, thought provoking material.

OK, that wasn't easy, and I link to most of the above regularly, but I hope that those stumbling upon this site for the first time will check out some of these blogs and find lots to interest them.

How goes the night

Since my hours became desynchronised with normal society while trying to brain-storm some ideas a couple of weeks ago I've had time, late at night, when my mind was no longer in the mood to follow equations on scraps of paper to read some interesting novels which I received for Christmas.

It's been a while since I raved about a Steinbeck, simply because I haven't been able to get hold of a new one for too many months. However, in my package of Christmas goodies I received a couple which I've been intrigued about for some time.

I've talked at length about my reasons for enjoying Steinbeck so much on this blog. To sum these feelings up though, it's Steinbeck's very simple but direct language which frequently takes my breath away. Steinbeck's books are about humanity, from the joy of life to the pains of death, of lost friendship, of unrequited love, of brotherly love and brotherly hate, and it's these extremes which somehow he manages to conjure, like cannon balls, out of simple words to make your core reverberate with empathy for the characters. Most of these characters in their totality are far from those in my life but every facet is somehow embedded in the man in the street, good friends and relatives and everyone in between. Steinbeck generally focuses his books on the West coast of America in the early 20th century but still his characters resonate with modern England.

However,not all of his books are set in the dust bowl, or the depression. Steinbeck was, for a short time, a war correspondent during the second world was and was a part of the allied propaganda machine, the war effort to inform those 'back home' that the boys were strong, that times were going to improve and that though the war was a terrible thing, it was really going to be alright in the end - I simplify greatly.

Once There was a War is a collection of Steinbeck's articles written during his stay in England, in North Africa and in Italy, spending time with the troops, sometimes under fire or sheltering during bombings, sometimes in the interminable times when simply nothing happened; the times when the nerves frayed and people lost their minds. Interestingly this is not Steinbeck's writing at its best. For a start he was writing for a cause, rather than for himself and his motivations are different, his writing was also edited with pieces of information removed when deemed inappropriate. I also think that he is best at dissecting the closed soul. Here he has the soul of the soldier magnified already and so the impact of what is already a powerful set of sentiments is lost a little. It's still a fascinating, important account of what it was like to be a private, to be sat waiting for your mission, the superstitions which built up, the personalities who were never affected by the pressure and those who simply crumpled and much more.

This form is however ideal for his studies of the individual. While it may be easy to think of the war in terms of large groups of people on vast missions, he uses his skills here to look at single soldiers as well as the collective feelings. This is really a book of well-written anecdotes, not about strategy and the art of war but, as always with Steinbeck, about people and what happens when they are pushed.

The second Steinbeck is also a book written during the war but this, historically, was almost certainly a more important book in terms of boosting the moral of the allies than Once There was a War. The title of The Moon is Down is taken from Macbeth indicating the 'descent of evil powers on the kingdom' (Introduction to Penguin classics version). The book is the tale of an unnamed town in an unnamed country, similar to Norway, invaded one day by an unnamed army. There is little struggle and at first the people simply don't know what to think. The book is a tale of the resilience and simple unwillingness to be dominated of this quiet, peaceful peoples to the force which had come to disrupt their existence.

The aim of the book was very similar to the aim of Once There was a War, to boost moral, to show that the allies could win through and that the determination of the good man and woman was enough to defend against the invading force.

When it was first published, the book was heavily criticised for treating the unnamed enemy as human beings. Indeed they came across as polite, respectful within their remit and fallible, not simply as mindless machines which were on a mission to destroy everything in their path. In fact these accusations were publicised and hurt Steinbeck deeply; he had simply done what he knew best, to put a real personality to all faces of humanity.

It only became apparent after the war that this had been quite simply one of the most important pieces of propaganda literature to come out during the occupation. The book had been smuggled through a huge swathe of Western and Northern Europe, published, copied, and published again in areas for which being found with the book almost certainly meant death. The people who read the book knew that the forces occupying their towns and villages were human beings, they would not have been fooled by Übermensch characters, and the book boosted the moral of the hundreds of thousands of people who were lucky enough to get their hands on it in the translated Norwegian, Danish, Dutch and French versions.

Again, this is not Steinbeck's greatest work of fiction but it's an important historical document and another example of his understanding of our true nature.

OK, it's now getting late and while I'm still awake I want to continue reading the new book by Becker, Becker and Schwartz: String Theory and M-theory: A Modern Introduction, which I'm borrowing from the Yukawa library and I am fast becoming convinced that this is the most in depth, accessible book on string theory yet published. I'll write more soon, but so far it's proving to be excellent.

Physics in a nutshell, in a nutshell

I've spent the last couple of evenings reading through one of several new graduate level textbooks on theoretical particle physics. Michael Dine's book Supersymmetry and String Theory, beyond the Standard Model is a concise, fact-filled book covering a huge range of topics. Within its 500 or so pages the Standard Model is summarised including a discussion of many non-perturbative effects in various gauge theories in diverse dimensions, a tour of the basic setups in non-supersymmetric model building, technicolour, supersymmetry, including SUSY breaking scenarios, general relativity, cosmology, astroparticle physics, plus string theory including discussions of many of the modern issues and many more topics besides.

However, because so much is packed in to this relatively short book, at times it feels more like an encyclopedia than a text book. It is a great resource if you know these things already and want to be reminded of the key points of a subject or, if you're not familiar with these subjects, to get a flavour of what's important and why. However, with this book alone you will not learn how to perform detailed calculations in many of these areas. The topics are just too deep for such short sections to get you up to research level. This is clearly not the idea though and there are many references pointing you to where you should go having got the basic ideas.

Some of the time this works very well but unfortunately on some occasions I think that the equations which are chosen for a given topic are confusing. That is to say that many steps are missed out and they may leave the reader who wants to learn these areas rather unsatisfied. This doesn't mean that a text book should give you a free ride but in this case the leaps are sometimes made without the necessary explanation. That said it covers so many of the key topics in modern beyond the standard model physics and I think this is the first text to do a good job of that.

The prerequisites I would suggest are a very thorough understanding of the standard model, including the basics of some non-perturbative physics and, perhaps surprisingly, supersymmetry. If you haven't come across supersymmetry before then the two pages in which the anticommutators of supercharges are introduced, the chiral, vector and supergravity (super)multiplets are given and superspace is discussed will probably leave you confused as to what's going on. This is easily remedied with one of the great reviews on the subject, but be warned that the encyclopedic breadth does leave it a little shallow at times.

So, as I say, if you have a reasonable idea of these topics already and want a good reference, or you want a text which will point you in the right direction for many areas of research then this is a great book. Despite the occasional large leaps in logic I'm enjoying reading this and the style in which it's written makes for a rather good overview of these diverse and fascinating topics.
