It is all good, but I particularly liked</p> <blockquote><p>when we ask climate scientists for future projections, we're asking the question of the scientists, not of their models. The scientists will apply their judgement to select appropriate versions/configurations of the models to use, they will set up the runs, and they will interpret the results in the light of what is known about the models' strengths and weaknesses and about any gaps between the comptuational models and the current theoretical understanding. And they will add all sorts of caveats to the conclusions they draw from the model runs when they present their results.</p></blockquote> </div> <span><a title="View user profile." href="/author/stoat" lang="" about="/author/stoat" typeof="schema:Person" property="schema:name" datatype="">stoat</a></span> <span>Thu, 12/02/2010 - 09:39</span> <div class="field field--name-field-blog-tags field--type-entity-reference field--label-inline"> <div class="field--label">Tags</div> <div class="field--items"> <div class="field--item"><a href="/tag/uncategorized" hreflang="en">Uncategorized</a></div> <div class="field--item"><a href="/tag/gcm" hreflang="en">gcm</a></div> <div class="field--item"><a href="/tag/modelling" hreflang="en">modelling</a></div> <div class="field--item"><a href="/tag/validation" hreflang="en">Validation</a></div> </div> </div> <section> <article data-comment-user-id="0" id="comment-1768672" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1291360458"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Steve is getting better and better.

Consequently, we model a zombie attack, using biological assumptions based on popular zombie movies. We introduce a basic model for zombie infection, determine equilibria and their stability, and illustrate the outcome with numerical solutions. We then refine the model to introduce a latent period of zombification, whereby humans are infected, but not infectious, before becoming undead. We then modify the model to include the effects of possible quarantine or a cure. Finally, we examine the impact of regular, impulsive reductions in the number of zombies and derive conditions under which eradication can occur. We show that only quick, aggressive attacks can stave off the doomsday scenario: the collapse of society as zombies overtake us all.</p></blockquote> <p>They use the mathematical models applied to outbreaks of infectious diseases to show that -- absent a cure or concerted eradication of large proportions of zombies simultaneously -- we are well and truly screwed. This realization should in no way detract from the observation that MATH IS COOL. It will be a damn shame when the zombies eat it out of our brains.</p> <p>Hat-tip: <a href="http://www.marginalrevolution.com/marginalrevolution/2009/08/mathematics-of-a-zombie-attack.html">Marginal Revolution</a></p> </div> <span><a title="View user profile." href="/author/purepedantry" lang="" about="/author/purepedantry" typeof="schema:Person" property="schema:name" datatype="">purepedantry</a></span> <span>Mon, 08/17/2009 - 13:27</span> <div class="field field--name-field-blog-tags field--type-entity-reference field--label-inline"> <div class="field--label">Tags</div> <div class="field--items"> <div class="field--item"><a href="/tag/cns-diseases-and-disorders" hreflang="en">CNS Diseases and Disorders</a></div> <div class="field--item"><a href="/tag/math" hreflang="en">math</a></div> <div class="field--item"><a href="/tag/modelling" hreflang="en">modelling</a></div> <div class="field--item"><a href="/tag/zombies" hreflang="en">zombies</a></div> </div> </div> <div class="field field--name-field-blog-categories field--type-entity-reference field--label-inline"> <div class="field--label">Categories</div> <div class="field--items"> <div class="field--item"><a href="/channel/social-sciences" hreflang="en">Social Sciences</a></div> </div> </div> <section> <article data-comment-user-id="275" id="comment-2482668" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1250535265"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Of course, this ALSO assumes that zombies do not need to feed constantly to maintain animation.

But killed zombies and humans by natural death go to the same removed class?</p> <p>I'm kind of thinking the model is built wrong if it intends to match film accounts (and the Brooks account) of zombies, where they are only made from the susceptible group, and shifted to the infected group. Natural death cases don't become zombies in most films. For that matter, a susceptible "losing" an encounter to a zombie ONLY results in infection, never in removal, in spite of the greater likelihood of dismemberment (and thus removal, rather than infection) in a losing encounter.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2482677&amp;1=default&amp;2=en&amp;3=" token="9I8zr7Sx3ET5NSSz7JiC6h39h6UZAtZeFsGs1rl3EJw"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Ty-bo (not verified)</span> on 18 Aug 2009 <a href="https://scienceblogs.com/taxonomy/term/12318/feed#comment-2482677">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2482678" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1250693763"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>I think this is the best thing I've ever seen in a paper:</p> <p>"This is, perhaps unsurprisingly, the first mathematical analysis of an outbreak of zombie infection."</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2482678&amp;1=default&amp;2=en&amp;3=" token="lHmm50mOCm2nsUM7eKh-Qe2-xNB8RKSDRAzCVXJUjbI"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">JohnV (not verified)</span> on 19 Aug 2009 <a href="https://scienceblogs.com/taxonomy/term/12318/feed#comment-2482678">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> </section> <ul class="links inline list-inline"><li class="comment-forbidden"><a href="/user/login?destination=/neurotopia/2009/08/17/best-modelling-paper-ever%23comment-form">Log in</a> to post comments</li></ul> Mon, 17 Aug 2009 17:27:12 +0000 purepedantry 144295 at https://scienceblogs.com
