The beauty of gravitational waves

Painting by Penelope Cowley depicting gravitational waves is being unveiled at Cardiff University's school of physics and astronomy on 25 November 2016

Science meets art – this painting by Penelope Cowley will be unveiled at Cardiff University’s school of physics and astronomy on 25 November.

By Matin Durrani

A new painting by Welsh artist Penelope Cowley is the latest attempt to bring art and science together. Set to be unveiled on Friday 25 November at Cardiff University’s school of physics and astronomy, the 1.2 × 1.5 m picture was inspired by the recent detection of gravitational waves by the LIGO collaboration.

According to the university, the oil painting “combines a visualization of data taken from the equipment used to detect the first gravitational waves…with an imagination of some of the celestial bodies that are responsible for creating these waves, such as binary black holes and neutron stars”.

Quantum technology 2.0

Niki Haines from Insight Technologies

Niki Haines from Insight Technologies predicts the future of quantum computing.

By Michael Banks

Are we on the verge of a “quantum 2.0” revolution?

That was a question raised yesterday at an event that I attended at HP Labs in north Bristol, which was organized by the University of Bristol.

The day-long meeting featured a series of talks from industry about how quantum technologies are affecting business.

Inspiring young physicists, telescope buyer’s guide, time-travelling pyramid builders

Have you ever wondered what inspires talented physicists to pursue careers in physics? To try to answer that question, the Perimeter Institute for Theoretical Physics (PI) in Canada has produced a set of tiles that explain how some famous physicists – and some up-and-coming stars – became hooked on physics at a young age. An early love of back-of-the-envelope calculations seems to have set the stage for the PI’s Asimina Arvanitaki as she explains in the above tile. Can you guess which Nobel laureate used to stare at a clock pendulum for hours to try to figure out how it worked? The answer to that teaser and much more can be found in “How great scientists get hooked on science”.

American angst

By Matin Durrani

Like many people, I’m fearful of the imminent Donald Trump presidency, given the many sexist, racist and otherwise unpleasant remarks he made during the US election campaign. However, his slogan – “Make America great again” – proved powerfully effective for many voters. Who, after all, could disagree with renewed domestic glory? Sadly, Trump’s plans for achieving that goal – what little we know of them – are based on such ill-informed and ignorant views that he could damage America’s long-standing leadership in many areas, including science.

Mars mission gains currency in India, nuclear obliteration and a super-duper moon

Nearly three years after it was successfully launched into orbit around Mars, India’s Mangalyaan orbiter has begun a new type of circulation – on a newly issued Indian banknote. Earlier this week, Indian prime minister Narendra Modi unexpectedly announced that the country’s ubiquitous Rs500 and Rs1000 notes would no longer be legal tender, effective immediately. New Rs500 and Rs2000 notes have instead be issued, the latter featuring the spacecraft.

Newton’s apple pips to form UK orchard

Logo of the first ever Internetional Science Center and Science Museum Day

Extending outreach: today is a worldwide celebration of science centres and museums.

By Matin Durrani

Today is not only World Science Day for Peace and Development (come on, don’t tell me you didn’t know) but also the world’s first ever International Science Center and Science Museum Day, which goes by the clunky acronym ISCSMD.

The grandiosely titled day seeks to “create new ways for our institutions to proactively address global sustainability while reaching increasingly diverse audiences”.

Building on UNESCO’s theme of “science for peace and development”, outcomes from the day’s events and discussions will be presented at the Science Centre World Summit 2017 in Tokyo next November.

Probing the quantum nature of water

 

By James Dacey in Beijing on Friday 4 November

After enjoying clear blue skies for the first couple of days of my visit to Beijing, the breeze has disappeared and the smog has taken its hold. One local scientist told me this latest wave is due to pollution from factories south-west of the city, but others have told me it is difficult to pinpoint a particular source. Facemasks are being worn by every other person in the streets, but fortunately I’ve been sheltered by the walls and ceilings of Peking University (PKU).

Robots at arXiv, physicist runs for US president, Einstein emojis galore

By Hamish Johnston

Last month the arXiv preprint server received more than 10,000 papers – the first time in the history of the physics paper depository. While arXiv papers are not peer reviewed, they are checked to ensure that they are “of interest, relevance and value” to the scientific community – which arXiv promises to do within 24 h of submission. So how do they do it? Surely someone doesn’t read every word of every paper? The answer can be found in “What counts as science?”, which appears in Nautilus. arXiv was set up in 1991 by the physicist Paul Ginsparg, who explains how the service uses machine learning to sort the wheat from the chaff – something that has attracted controversy.

Science elevator pitches in Beijing

 

By James Dacey in Beijing

Could you provide a short entertaining presentation of your research to a non-specialist audience, leaving them feeling both enlightened and inspired? How about trying to do it in a non-native tongue? That’s what several Chinese researchers did on Wednesday evening at the Science Slam event at the European Delegation headquarters in Beijing. The event was part of a day-long communications training workshop aimed at researchers who want to communicate their research to the general public and improve their ability to apply for research grants.

Physics of food – the November 2016 issue of Physics World is now out

 

By Matin Durrani

If you love crisps – and frankly who doesn’t? – you’ll relish the cover feature of the latest issue of Physics World, in which features editor Louise Mayor tours the world’s biggest crisp factory at Leicester in the UK to see how physics is improving production of this yummy salty snack. The issue is now live in the Physics World app for mobile and desktop and will also be made available on physicsworld.com later this month.

Elsewhere in this special issue on physics and food, you can find out how electric fields could help to cut the fact from chocolate and discover why sound holds the key to our appreciation of what we eat.

You can also see how physicists – being masters of data-gathering, modelling and simulation – are ideally placed to develop products that are healthier, more nutritious and make more of our resources. Find out too how soft-matter physicists are crafting “functional” foods that promote feelings of fullness and satisfaction.
