Interversity, a concept for self-organizing distributed university Mixel Kiemen Abstract: Universities are historically seen as places of universal knowledge. Because of information overload and the acceleration of innovation, the concept of universal knowledge is becoming an illusion. How does Tupper’s self-referential formula work? [I write this post with a certain degree of embarrassment, because in the end it turns out (1) to be more simple than I anticipated, and (2) already done before, as I could have found if I had internet access when I did this. :-)] The so-called “Tupper’s self-referential formula” is the following, due to Jeff Tupper. Graph the set of all points such that in the regionwhere N is the following 544-digit integer: 48584506361897134235820959624942020445814005879832445494830930850619 34704708809928450644769865524364849997247024915119110411605739177407 85691975432657185544205721044573588368182982375413963433822519945219 16512843483329051311931999535024137587652392648746133949068701305622 95813219481113685339535565290850023875092856892694555974281546386510 73004910672305893358605254409666435126534936364395712556569593681518 43348576052669401612512669514215505395545191537854575257565907405401 57929001765967965480064427829131488548259914721248506352686630476300 The result is the following graph: .

Parametric polymorphism For example, a function append that joins two lists can be constructed so that it does not care about the type of elements: it can append lists of integers, lists of real numbers, lists of strings, and so on. Let the type variable a denote the type of elements in the lists. Then append can be typed [a] × [a] -> [a], where [a] denotes the type of lists with elements of type a.

8 math talks to blow your mind Mathematics gets down to work in these talks, breathing life and logic into everyday problems. Prepare for math puzzlers both solved and unsolvable, and even some still waiting for solutions. Ron Eglash: The fractals at the heart of African designs When Ron Eglash first saw an aerial photo of an African village, he couldn’t rest until he knew — were the fractals in the layout of the village a coincidence, or were the forces of mathematics and culture colliding in unexpected ways? Statistical Thinking: The Bedrock of Data Science By Joel B. Greenhouse Thanks to Google Chief Economist Hal Varian's 2009 prediction that "the sexy job in the next 10 years will be statisticians," it is now OK to self-identify as a statistician. This calls for some explanation.

Polymorphism (biology) Dark-morph or melanistic jaguar (about 6% of the South American population) Polymorphism[1] in biology occurs when two or more clearly different phenotypes exist in the same population of a species — in other words, the occurrence of more than one form or morph. In order to be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating).[2] Polymorphism as described here involves morphs of the phenotype. The term is also used somewhat differently by molecular biologists to describe certain point mutations in the genotype, such as SNPs (see also RFLPs). This usage is not discussed in this article.

Your implants translate: Akemi explains that her navigation system (formerly known as GPS) just failed. She is asking if she can connect to yours in order to find her way. You would like to accept, but your second I panics: What happened in the background of your digital integrated agents? Of course, as soon as she opened her mouth, you knew everything about her (educational background, social graph, health, until the quality of her pheromones), except perhaps the essential and what she wanted hide. The Paradox of the Proof On August 31, 2012, Japanese mathematician Shinichi Mochizuki posted four papers on the Internet. The titles were inscrutable. The volume was daunting: 512 pages in total. The claim was audacious: he said he had proved the ABC Conjecture, a famed, beguilingly simple number theory problem that had stumped mathematicians for decades. Then Mochizuki walked away.

Huffington Post Co-authored with Catherine M. Machalaba, MPH Novel diseases and pandemics have captured our global attention. Polymorphism (computer science) In programming languages and type theory, polymorphism (from Greek πολύς, polys, "many, much" and μορφή, morphē, "form, shape") is the provision of a single interface to entities of different types.[1] A polymorphic type is a type whose operations can also be applied to values of some other type, or types.[2] There are several fundamentally different kinds of polymorphism: If a function denotes different and potentially heterogeneous implementations depending on a limited range of individually specified types and combinations, it is called ad hoc polymorphism. Ad hoc polymorphism is supported in many languages using function overloading.If the code is written without mention of any specific type and thus can be used transparently with any number of new types, it is called parametric polymorphism. In the object-oriented programming community, this is often known as generics or generic programming.
