The periodic table turns 150 years old in the year 2019, which has been appropriately designated as the International Year of the Periodic Table by the UNESCO Organization.
The Democratic Party’s 2008 presidential primary was supposed to be the coronation of Hillary Clinton. She was the most well-known candidate, had the most support from the party establishment, and had, by far, the most financial resources.
The coronation went off script. Barack Obama, a black man with an unhelpful name, won the Democratic nomination and, then, the presidential election against Republican John McCain because the Obama campaign had a lot more going for it than Obama’s eloquence and charisma.
Coffee is one of the most traded commodities in the world, valued at more than $100 billion annually. Even if you’re not an entrepreneur looking for the next big coffee venture, you’ll probably still care about how to make the 2.25 billion cups of coffee globally consumed every day as delicious as possible.
Most practicing scientists scarcely harbor any doubts that science makes progress. For, what they see is that despite the many false alleys into which science has strayed across the centuries, despite the waxing and waning of theories and beliefs, the history of science, at least since the ‘early modern period’ (the 16th and 17th centuries) is one of steady accumulation of scientific knowledge. For most scientists this growth of knowledge is progress. Indeed, to deny either the possibility or actuality of progress in science is to deny its raison d’être.
Kicking off the International Congress of Mathematicians 2018 in Rio de Janeiro was this year’s Fields Medal awards ceremony, celebrating the brightest young minds in mathematics. The prize is awarded every four years to up to four mathematicians under the age of 40, and is viewed as one of the highest honours a mathematician can receive.
This year, 2018, sees the world’s mathematics community come together once more at the International Congress of Mathematicians, hosted for the first time in South America in Rio de Janeiro. A highlight at every ICM is the announcement of the recipients of the Fields Medal, an award that honours up to four mathematicians under the age of 40, and is viewed as one of the highest honours a mathematician can receive. Here we honour past Fields Medal winners who we are proud to name as our authors. Hover over each name to learn a little more about who they are and what their contributions have been.
Why should a trained scientist be seriously interested in science past? After all, science looks to the future. Moreover, as Nobel laureate immunologist Sir Peter Medawar once put it: “A great many highly creative scientists…take it for granted, though they are usually too polite or too ashamed to say so, that an interest in the history of science is a sign of failing or unawakened powers.”
As a mathematician who focuses his attention on a field called dynamics, I am often asked when queried about my area of specialty, exactly what is a dynamical system? I usually answer something like: “I study the mathematics underlying what is means to model something mathematically.” And this seems to work as most people have a basic understanding that mathematics is used in science and engineering to model either a physical or an abstract process and to mine it for information.
When a group of people collectively solve a jigsaw puzzle, who gets the credit? The person who puts the final piece in the puzzle? The person who sorted out the edge pieces at the beginning? The person who realised what the picture was of? The person who found the puzzle pieces and suggested trying to put them together? The person who managed the project and kept everyone on track? The whole group?
“What connects archaeology and statistical physics?”, we asked ourselves one evening in The Marquis Cornwallis, a local Bloomsbury pub in London back in 2014, while catching up after more than a decade since our paths crossed last time. While bringing back the memories of that time we first met when we were both 16, it hit us that our enthusiasm for research we did as teenagers had not faded away
Mathematics is more than the memorization and application of various rules. Although the language of mathematics can be intimidating, the concepts themselves are built into everyday life. In the following excerpt from A Brief History of Mathematical Thought, Luke Heaton examines the concepts behind mathematics and the language we use to describe them.
Chinese scientists have recently announced the use of a satellite to transfer quantum entangled light particles between two ground stations over 1,000 kilometres apart. This has been heralded as the dawn of a new secure internet. Should we be impressed? Yes – scientific breakthroughs are great things. Does this revolutionise the future of cyber security? No – sadly, almost certainly not.
Alan Turing was one of England’s most influential scientists of the twentieth century. He is best remembered as having cracked the codes used in the Enigma machines, enabling the Allies to defeat the Nazis in many important battles, particularly in the Atlantic Ocean. While this achievement which arguably helped to bring the Second World War to a quicker end has been brought to the fore through popular histories
There is a concern that too many scientific studies are failing to be replicated as often as expected. This means that a high proportion is suspected of being invalid. The blame is often put on confusion surrounding the ‘P value’ which is used to assess the effect of chance on scientific observations. A ‘P value’ is calculated by first assuming that the ‘true result’ is disappointing
Game theory is considered to be one of the most important theories not simply within the field of economics, but also mathematics, political science, biology, philosophy, and ecology, just to name a few. It has been developed over the many years since the term was first coined to what it is now: a theory used to “understand the strategic behaviour of decision makers who are aware that their decisions affect one another.”
In fact the idea really goes back to Michael Faraday, who gave Christmas lectures about science for young people at The Royal Institution of Great Britain in London in 1826. Sir Christopher Zeeman, following upon Porter’s initiative, gave the first series of six one-hour lectures (Mathematics Masterclasses) to young people at The Royal Institution in 1981, about “The Nature of Mathematics and The Mathematics of Nature”.
