It's not very often that something I read makes me want to jack in my lovely job at Plus and return to study and research. But that is just what happened when reading "Sync" by Steven Strogatz.
The book tells the story of how questions from diverse areas — Why do we sleep when we do? How do fireflies flash in unision? Why does our heart beat? How do you link generators in a power grid? — have developed into a new field of study. This new field, which Strogatz calls synchrony, examines how order can spontaneously break out in complex systems. The role of sync in such diverse areas of science is fascinating, but equally fascinating is his evocative description of the process of doing this research. Strogatz describes theoretical concepts and research problems almost as if they were physical entities that you could touch or smell.
The media is buzzing with swine flu numbers. Latest government figures say that over 100,000 people in England came down with swine flu during the last week — that's almost twice the amount of the previous week, and up to five times higher than the seasonal flu figures recorded last winter. Twenty-six people in England have died of the disease.
But where do the numbers come from? Patients with swine flu symptoms are no longer tested in the lab or traced, so the published figures are estimates, rather than absolute numbers.
As part of our celebration of the International Year of Astronomy 2009 we brought you the article Are the constants of nature really constant?, in which John D. Barrow tells us how it all depends on which constants you choose. In the podcast of this interview you can hear how changes in the constants that define our
Universe might have implications for extra dimensions, gravity, and climbing flies...
What would you like to know about your Universe — The fourth online poll
This poll is now closed. The most popular question was: "How does gravity work?" You can read the answer on Plus, or listen to the podcast. Thank you for taking part and don't forget to vote in the current
This is the fourth online poll in our series to celebrate the International Year of Astronomy 2009. Choose your favourite question from the list on the right, and we'll put the one that proves most popular to world-leading astronomers and cosmologists, including Astronomer Royal Martin Rees and author and cosmologist John D. Barrow. The poll will
remain open for a month and the answer will be published in a Plus article and podcast soon after. If your most burning question is not on this list, then leave a comment on this blog and we'll endeavour to include it in a future poll — there will be three more polls dotted throughout the year.
