You can run, You can hide: Surviving a Zombie Apocalypse
Have you ever wondered what your chances of survival might be during a Zombie apocalypse? A team from the Laboratory of Atomic and Solid State Physics at Cornell University have published a paper that might help you answer that question.
You can see their paper, entitled “You Can Run, You Can Hide: The Epidemiology and Statistical Mechanics of Zombies” on Arxiv at arxiv.org/abs/1503.01104
Zombies, the authors say, “form a wonderful model system to illustrate modern epidemiological tools drawn from statistical mechanics, computational chemistry, and mathematical modeling.”
So what does this mean for you and me – people who just want to know our chances? If you read the paper, you'll see they perform an in-depth analysis, developing models for the potential spread of a Zombie invasion, then they apply those models to a hypothetical Zombie outbreak in the USA.
One of the factors they take into account is that the outcome changes depending on what model you use and what starting parameters you choose. These starting parameters are such things as the likelihood of being infected if you encounter a Zombie, where and with how many Zombies does the outbreak start, how likely you are to kill the Zombie, and other relevant factors.
They then run many different simulations for an outbreak in the USA, using the different models and
a selection of (what one might refer to as) credible starting parameters, and using a large collection of results they develop what they call a susceptibility map. Depending on where you live, what are your chances?
You'll have to see their maps to get the full answer, but I have to say, I wouldn't fancy my chances in Bakersfield, California. There's good news, though, for those of you who live in remote parts of Montana and Nevada. They found that after just one week, most of the population of the US would be infected, but four months later, remote parts of Montana and Nevada would still be Zombie-free!
Just watch those house prices go up when this hits the headlines.

Book Review: The Sensorium of God by Stuart Clark
Sparks of Genius – The momentous clash of Isaac Newton and
Robert Hooke.
This is the second in Stuart Clark's trilogy, including The Sky'sDark Labyrinth, The Sensorium of God and The Day Without Yesterday. Each takes a pivotal moment in the evolution of science and dramatises it in fiction.
From the back cover
It is the late seventeenth century and the movement of the planets remains a mystery despite the revolutionary work of Johannes Kepler, Galileo Galilei and Tycho Brahe almost a hundred years before.
Edmond Halley - dynamic adventurer and astronomer - seeks the help of Isaac Newton in unravelling the problem, but, though obsessed with understanding the orbits of the planets, Newton has problems of his own. The reclusive mathematician and alchemist has a guilty secret. He stole some of his ideas from Robert Hooke, and the quarrelsome experimentalist is demanding recognition.
While capable of contemplating the loftiest ideals and theories, the three men are just as quick to argue, and their grudges could derail the quest for scientific truth. The men's lives and work clash as Europe is pushed headlong towards the Age of the Enlightenment and science is catapulted into its next seismic collision with religion.
The Sensorium of God by Stuart Clark
Stuart Clark's effortless writing style and vivid period descriptions bring to life a story that is so often related in dusty, dry academic texts. The book is a joy to read. Stuart Clark's deep knowledge, not only of the historical setting, but of the underlying science and astronomy and the lives of the scientists involved, ensures that this story is not only engaging, but it is historically accurate. This is a book which carries a considerable promise, whether your background is in science or not. I am happy to say that Stuart Clark does not fail to deliver the goods.
This story focusses on the events surrounding Isaac Newton, Edmond Halley and Robert Hooke at the time when Newton was working on perhaps his most famous works, his Principia and Opticks. We also meet such notable characters as Gottfried Leibniz, John Flamsteed, Samuel Pepys, Christopher Wren and a veritable roll call of other well known people of the age.
It is a time when parliament and the crown are vying for power, much of which rested with the monarch, who used the church as a vehicle for control. We begin at the time of Charles II, and in short time, we see James II ascend to the throne, followed by William and Mary. Heresy was still a capital offence, and religious oppression was perpetrated by Catholics and Protestants alike. Along with the suppression of any religious views that conflicted with church doctrine, any scientific claims that could be – even at at stretch – considered out of line with church doctrine, could lead to accusations of heresy.
In these times of political and religious instability, prominent scientists such as Newton, Halley and Liebniz walked the fine line between provoking religious or political wrath, and becoming the victims of the deeds or misdeeds of others.
We see the fascinating relationship between Newton, his alchemy and his science, and his sexual curiosity about the young mathematician Fatio, as well as the unconventional relationship between the irascible Hooke and his niece, Grace.
Stuart Clarke weaves a compelling tale, with fascinating insights into the flawed characters of Newton, Halley and Hooke. He brings the people and locations to life so well that you can see them and smell them. This is fine writing and story-telling, which never loses its pace and depth, and with no shortage of action and intrigue.

Francesca's Bookshelf: Percy's Reliques
“Consisting of old heroic ballads, songs and other pieces of our
earlier poets together with some few of later date”
Francesca loves her ballads and songs, and with plenty of spare time and little else to spend her money on, she has assembled a formidable collection of old books, many of them containing ancient collections of ballads. She is pleased to find a copy of the three volume set of Reliques of Ancient English Poetry, a collection put together by the Rev. Thomas Percy in the 18th Century, and commonly known as Percy's Reliques. The full three volume set is hard to find, and she pays a high price for the set.
We owe Percy a lot, as the inspiration for subsequent generations of collectors and singers. Without his work, fewer of these old ballads and songs would be available to us today, and artists such as Steeleye Span, Fairport Convention and many others would have had a poorer access to our traditional songs and ballads.
This collection, first published in 1765, was one of the earliest published collections of ballads, and at a time when ballads were popularly thought of as vulgar street songs, it shone a new light on the form, providing future generations with a window into the past of these wonderful gems. Indeed, his work provided inspiration for future collectors such as Child, Scott, Jamieson, Motherwell and Buchan to name but a few. Notably, the Rev. R. A Willmott produced a single “handy volume” revision of the Reliques in 1857, entitled Percy's Reliques, in which he cleared away all Percy's essays and prefaces, and added annotation of his own.
Henry B. Wheatley, edited the 1885 three volume edition photographed above (this copy is a 1927 reprint). According to Wheatley, Thomas Percy was born in 1729 in Bridgenorth in Shropshire. He matriculated at Christ Church College, Oxford in 1746 and achieved his Masters degree in 1750. In 1753, at the age of 24, he was made rector of Easton Maudit in Northampton. As a young man he came into possession of an unbound manuscript in poor condition. Of it, he said, “I saw it lying dirty on the floor, under a bureau in ye parlour: being used by the maids to light the fire …” Happily he was able to rescue the manuscript, and this, along with other collections, printed broadsides and other sources, provided the material from which he derived the Reliques. Percy's precious rescued manuscript itself was probably written shortly before 1650, and was used extensively by Child more than a hundred years later.
Percy died in 1811 at the ripe old age of 83.
On the left is Willmott's "handy volume" edition. Percy's Reliques. This copy is not dated by the publisher or printer, but the inscription in the front is as a prize, given in 1879.
This edition contains a small number of illustrations, like the one shown here.
As an interesting footnote, I should add that, although Percy titled his work "Reliques of Ancient English Poetry", the collection does not contain only English poetry! As an example, some ballads such as Sir Patrik Spence, and Edward, Edward are Scottish, as he states in the text.
I have scanned some pages from Wheatley's 3 volume set for your delight. What follows is a ballad entitled On Thomas Lord Cromwell, from the second volume. I chose this because Thomas Cromwell is currently being depicted in the media in a television dramatisation of Hilary Mantel's novel Wolf Hall. Percy prefaces the ballad with a brief essay, and this is followed by [in square brackets] Wheatley's own comments. The ballad is written in archaic language, which makes it a challenge to read if you're not used to it, but it's worth the effort. Just click on the images to enlarge them.
I hope you've enjoyed this little trip into the life of Thomas Percy.

Touchdown! Rosetta's Success Story and the Philae Lander
Image courtesy ESA
Huge congratulations to the ESA Rosetta mission team! They have done what some said was impossible. The image above is a photo taken by the Rosetta craft of the Philae lander shortly after it was released for its descent onto comet 67P/Churyumov-Gerasimenko.
Seven hours later, this afternoon at 1603 GMT, the signal was received confirming that the Philae lander has touched down on the surface of 67P/Churyumov-Gerasimenko.
This success paves the way for ground-breaking research. The Philae lander is equipped to take images of the comet's surface, but it can do much more than that. If its battery remains serviceable and the Philae lander remains anchored to the comet, it will analyse the composition of the surface, drill for samples, and send back an analysis. It will use radio signals to probe the comet's structure, and all in all, it will provide a wealth of data about the comet.
So... why do we care?
Comets and asteroids are considered interesting because scientists believe that they are the leftover remnants from the formation of the solar system some 4.5 billion years ago. Comets are particularly interesting because they ended up in the outer reaches of the solar system, in the Kuiper belt and the Oort cloud. These places are cold - about 50 degrees above absolute zero, and because of this extremely low temperature, the composition of comets has changed little since they were formed.
Comets are well known for being made up of dust, rock and frozen gasses, including water ice. There is evidence that the water in comets could be the source of water on Earth, and this is particularly interesting because those very same comets contain a wealth of organic molecules - the building blocks of amino acids, protein, and hence, life itself.
So what we see when we get up close and personal with a comet such as 67P/Churyumov-Gerasimenko is a window into the past. So far in the past that we gain clues to the processes that took place during the very formation of the solar system. This in its turn gives us clues about our own past.
The Rosetta mission, and particularly the Philae lander, can teach us much about the early years of the solar system, and even give us clues about the formation of the Sun itself.
For so many reasons this success is a source of excitement, not only for the scientific community, but for everybody.
Congratulations to the ESA Rosetta mission team. May your successes continue and your data be plentiful.
A Big Day for the Rosetta Team
Today is a big day for the Rosetta team. This morning, in Darmstadt, the ESA flight team gave the go-ahead to release the Philae lander on its way for an historic landing on the comet 67P/Churyumov-Gerasimenko.
This mission, which was first conceived in the 1980s, has been many years in the making. It was launched on 2nd March 2004 with the objective of visiting this comet. Over a period of ten years, Rosetta navigated a complex series of ever increasing orbits of the sun, until on 6th August this year it achieved a successful rendezvous with 67P/Churyumov-Gerasimenko.
Rosetta is the first craft to have made a rendezvous with a comet, and the success of the Philae lander is by no means certain. What happens today will be a complex and difficult landing, and the eyes of the world will be on the live feeds.
I want to wish the team success with this bold endeavour.

NaNoWriMo 2014 - Here we go...
This is it. Tomorrow, National Novel Writing Month 2014 begins, and during the month of November, hundreds of thousands of people across the world will endeavour to write a 50,000 word novel in 30 days.
Why do we do it?
There are almost as many answers to that question as there are participants. Some want to be published, some write only for their own pleasure, but one thing I find is common to all - we do it because we love writing.
To write a 50,000 word novel in 30 days seems like an almost insurmountable challenge until you realise that it amounts to a modest daily target of 1667 words. Many authors set themselves daily word count targets, and 2000 words per day is not uncommon.
NaNoWriMo participants come from all walks of life, and while 1667 words might be a modest aspiration, not everyone has time to reach that goal. Life gets in the way. Some people start NaNoWriMo with firm intentions, but for one reason or another, cannot reach the big goal of 50,000 words. In the end, though, every participant has thought more about writing, and most have written more than they would have done without the challenge.
That's why I say that every one of the hundreds of thousands of people who sign up for NaNoWriMo will surely be a winner.
