from the editor

Here it is, your first issue of the new-look BBC Science Focus. What’s changed? We listened to your feedback and have tried to give you more of what you love. As a result, Discoveries (p15) is bigger and better, providing more insight and analysis into the news that matters. The same goes for Q&A (p75), where the changes we’ve made will let us answer your brilliant questions in more detail than before. I’d also like to introduce our new section, Reality Check (p32), where we look at the science behind the headlines. In a world where measles is making a comeback, and politicians ignore climate change because it’s snowing, it seemed vital to provide a voice of reason to cut through the nonsense. This month, we look at what you can…

eye opener

Eye on the sky BEIJING, CHINA This isn’t a close-up of some newly discovered spider, but a bird’s-eye view of Beijing Daxing International Airport, currently under construction. The ‘eyes’ are skylights over the main hub of the terminal. The gates will be located along five spokes radiating from the centre, reducing the distance passengers have to walk: the maximum time to a gate should be eight minutes. When it opens in September 2019, its four runways will serve 72 million passengers annually. The subsequent opening of a further three runways will bring that number to over 100 million, making it the world's busiest airport. In comparison, London Heathrow served 80 million people in 2018.

leeter of the month

Moon musings With regard to the article A New Race To The Moon Has Begun in your current edition, (February, p32) the science-fiction writer, the late Robert A Heinlein, once wrote: “The laws of nature are not the exclusive property of any group or society; they belong to anyone prepared to make use of them.” At the time, he was warning of the danger of the US space program losing ground to the Japanese, but it is at least equally relevant to the Chinese. As various commentators have pointed out, a few centuries ago, the Chinese Empire sent a number of expeditions – utilising ships significantly larger than their Western equivalents – down the eastern coast of Africa. Had the expeditions continued, Western and Chinese ships could have met, somewhere around the Cape,…

@StephenCWLL In an effort to stop getting behind on reading, I’ve made a cuppa and sat down for two straight hours to get through latest @sciencefocus magazine in record time. @Dolichon Nearly through Dry January and I haven’t noticed any improvement in health or well being. Does that mean I wasn’t drinking enough? It turns out that a lot of you have heard of James Clerk MaxwellÉ @sciencefocus James Clerk Maxwell: the most important physicist you probably haven’t heard of @Interesting_Ian Eh?? Never heard of? Would have thought most people would have heard of him. I haven’t heard of the majority of celebrities, but have certainly heard of Maxwell! @wfastronomer Born in India St in Edinburgh. The Physics and Astronomy Department building in Edinburgh is the James Clerk Maxwell Building, and there is a James Clerk Maxwell Telescope in Hawai’i,…

A moment of reflection I’m currently serving with the RAF in the Falkland Islands, and have never missed a copy since I started a subscription some 17 years ago. I managed to put a few to one side before coming out here, and much to my displeasure I noticed that in issue 326 (September) the question about whether opposing mirrors produce infinite reflections (bit.ly/mirrors_reflection) won Question Of The Month, and was awarded a Skullcandy headset... Well, I sent that very same question in some 12 or 13 years ago, but I wasn’t given the honour of Question Of The Month nor did I win a prize for ingenuity, originality or even for my handwriting ... If spending six months away from my family in the middle of nowhere defending this small section of…
