In her book Beyond Infinity, Dr Eugenia Cheng explores the inner workings of infinity, a mysterious concept that we all know about from childhood, but never truly claim to understand.

There are infinite facts in the book (well, quite a lot at any rate), but here’s just a fraction for now. Infinity plus one Imagine an infinite hotel with rooms numbered 1, 2, 3, 4 and so on forever. Even if it was full you could always fit in another guest - just ask all the old guests to move up one room, leaving room 1 free for the new guest. However, this does cause an infinite hassle, as all the guests have to move rooms. Same means, standard deviations and correlation! by @JustinMatejka & Fitzmaurice.

Countdown of Top 10 Reasons to Never Ever Use a Pie Chart (The Designer Experience) Pie charts are evil.

They represent much of what is wrong with the poor design of many websites and software applications. They're also innefective, misleading, and innacurate. Using a pie chart as your graph of choice to visually display important statistics and information demonstrates either a lack of knowledge, laziness, or poor design skills. Figure 1: A floating, tilted, 3D pie chart with shadow trying (poorly)to show usage statistics within a graphics application. Of course, pie charts in and of themselves are not evil. Figure 2: Pie Chart from an Oracle Reports User Guide A pie chart does not do the job of effectively displaying information in an elegant visual form.

The Map of Mathematics: Animation Shows How All the Different Fields in Math Fit Together Open Culture. Back in December, you hopefully thoroughly immersed yourself in The Map of Physics, an animated video–a visual aid for the modern age–that mapped out the field of physics, explaining all the connections between classical physics, quantum physics, and relativity.

You can’t do physics without math. Hence we now have The Map of Mathematics. Created by physicist Dominic Walliman, this new video explains “how pure mathematics and applied mathematics relate to each other and all of the sub-topics they are made from.” Watch the new video above. You can buy a poster of the map here. ***Why Numbers Matter [Episode 2: Do Maps Lie?] Changing Places. Stacked Column Chart - amCharts. I-Use - Statistics in education. Data overwhelms our modern lives, however statistical approaches offer tools to help us to organise and interpret data.

The I-USE project has involved the creation of a website which provides easily accessible statistics; some ready-made and some via links to databases. The aim is to increase the use of updated statistics in education for both students and teachers, and develop thinking about the misuse of statistics, so that teachers are more statistically literate. One main objective of I-Use has been to focus on teaching and learning activities considered necessary for the professional development of teachers who can support their students in becoming statistically literate, capable of reasoning information and making informed decisions based on quantitative information.

How statistics lost their power – and why we should fear what comes next. In theory, statistics should help settle arguments.

They ought to provide stable reference points that everyone – no matter what their politics – can agree on. Yet in recent years, divergent levels of trust in statistics has become one of the key schisms that have opened up in western liberal democracies. Shortly before the November presidential election, a study in the US discovered that 68% of Trump supporters distrusted the economic data published by the federal government. In the UK, a research project by Cambridge University and YouGov looking at conspiracy theories discovered that 55% of the population believes that the government “is hiding the truth about the number of immigrants living here”. Rather than diffusing controversy and polarisation, it seems as if statistics are actually stoking them.

Here at FiveThirtyEight, we tend to think statistics can add to our understanding of sports. (What a surprise!) From the more mature sabermetric movements of baseball and basketball to growing ones in soccer and hockey, evidence-based examination has led to new thoughts and ideas about the games we love. But there can also be a dark side to analytics. Among other potential pitfalls, interpreting the numbers incorrectly can lead to terrible decisions or encourage habits that are hard to break, particularly given the added weight that conclusions carry if they appear to emerge from hard data.

Online teaching resources. CBA and intangibles: The McNamara Fallacy and the Problem with Numbers in Education. Robert McNamara was by any standards, a wildly successful man. Harvard graduate, president of Ford motors then rising to the heights of U.S. Secretary of Defense in the 1960s, McNamara epitomised American élan and brio. But he had one major flaw – he saw the world in numbers. During the Vietnam War, McNamara employed a strategic method he had successfully used during his days at Ford where he created data points for every element of production and quantified everything in a ruthless fashion to improve efficiency and production.

One of the main metrics he used to evaluate progress and inform strategy was body counts. The problem with this method was that the Vietnam war was characterised by the unmeasurable chaos of human conflict not the definable production of parts on a factory assembly line. As the war became more and more untenable, McNamara had to increasingly justify his methods. 1. 2.
