Really big numbers

What is the biggest whole number that you can write down or describe uniquely? Well, there isn’t one, if we allow ourselves to idealize a bit. Just write down “1”, then “2”, then… you’ll never find a last one.

A person-less variant of the Bernadete paradox

Before looking at the person-less variant of the Bernedete paradox, lets review the original: Imagine that Alice is walking towards a point – call it A – and will continue walking past A unless something prevents her from progressing further.

Is elementary school mathematics “real” mathematics?

When people think of elementary school mathematics, they usually bring to mind number facts, calculations, and algorithms. This isn’t surprising, as these topics tend to dominate classroom work in many elementary schools internationally. There is little doubt that elementary students should know the multiplication tables, be able to do simple calculations mentally, develop fluency in using algorithms to carry out more complex calculations

Measuring up

My first degree was in mathematics, where I specialised in mathematical physics. That meant studying notions of mass, weight, length, time, and so on. After that, I took a master’s and a PhD in statistics. Those eventually led to me spending 11 years working at the Institute of Psychiatry in London, where the central disciplines were medicine and psychology. Like physics, both medicine and psychology are based on measurements.

Very short facts about the Very Short Introductions

This week we are celebrating the 500th title in the Very Short Introductions series, Measurement: A Very Short Introduction, which will publish on 6th October. Our expert authors combine facts, analysis, new ideas, and enthusiasm to make often challenging topics highly readable. To mark its publication editors Andrea Keegan and Jenny Nugee have put together a list of Very Short Facts about the series.

Just because all philosophers are on Twitter…

Just because everyone is on Twitter doesn’t mean they’ve all got interesting things to say. I vaguely recall reading that late 19th-century curmudgeons expressed similar scepticism about the then much-hyped technology of the telephone.

Teaching teamwork

The capacity to work in teams is a vital skill that undergraduate and graduate students need to learn in order to succeed in their professional careers and personal lives. While teamwork is often part of the curriculum in elementary and secondary schools, undergraduate and graduate education is often directed at individual effort and testing that emphasizes solitary performance.

What is combinatorics?

The subject of combinatorial analysis or combinatorics (pronounced com-bin-a-TOR-ics) is concerned with such questions. We may loosely describe it as the branch of mathematics concerned with selecting, arranging, constructing, classifying, and counting or listing things.

A brief history of crystallography

So, what is crystallography? Put simply, it is the study of crystals. Now, let’s be careful here. I am not talking about all those silly websites advertising ways in which crystals act as magical healing agents, with their chakras, auras and energy levels. No, this is a serious scientific subject, with around 26 or so Nobel prizes to its credit. And yet, despite this, it remains a largely hidden subject, at least in the public mind.

Today’s Forecast: Cloudy with a chance of seizures

For people suffering from recurrent epileptic seizures, one of the most burdensome aspects of their condition is the unpredictability of their seizures. While medications, surgery, and novel neurostimulation methods can eliminate seizures seizures in some cases, many people with epilepsy face the possibility of a seizure at any time, even when they occur only rarely.

Doing it with sensitivity

I’m sure you’ve had this experience. You want to get somewhere, say a concert, or a public building, and all the people are stopped by security officials, who ask to search your bag. They open it, maybe take out one or two items, then glance around inside the rest, before giving it back to you and letting you go.

Can design thinking challenge the scientific method?

The scientific method has long reigned as the trusted way to test hypotheses so as to produce new knowledge. Shaped by the likes of Francis Bacon, Galileo Galilei, and Ronald A. Fisher, the idea of replicable controlled experiments with at least two treatments has dominated scientific research as a way of producing accepted truths about the world around us. However, there is growing interest in design thinking, a research method which encourages practitioners to reformulate goals, question requirements, empathize with users, consider divergent solutions.

The consistency of inconsistency claims

A theory is inconsistent if we can prove a contradiction using basic logic and the principles of that theory. Consistency is a much weaker condition that truth: if a theory T is true, then T consistent, since a true theory only allows us to prove true claims, and contradictions are not true. There are, however, infinitely many different consistent theories that we can construct.

Mary Somerville: the new face on Royal Bank of Scotland’s ten-pound note is worthy of international recognition

From 2017, ten-pound notes issued by the Royal Bank of Scotland will feature a new face: that of the great nineteenth-century science communicator Mary Somerville. Her book on mathematical astronomy, Mechanism of the Heavens — published in 1831, when she was fifty years old — was used as an advanced textbook at Cambridge for a hundred years. This is a phenomenal achievement for a woman who taught herself science and mathematics.

Earth’s climate: a complex system with mysteries abound

We are living with a climate system undergoing significant changes. Scientists have established a critical mass of facts and have quantified them to a degree sufficient to support international action to mitigate against drastic change and adapt to committed climate shifts. The primary example being the relation between increased atmospheric carbon dioxide concentrations and the extent of warming in the future.

What is information, and should it be free?

When we pay our bills using a plastic card, we are simply authorizing alterations to the information stored in some computers. This is one aspect of the symbiotic relationship that now exists between money and information. The modern financial world is byzantine in its complexity, and mathematics is involved in many ways, not all of them transparently clear. Fortunately there are some bright spots, such as the fact that it is now possible to measure information.
