From complex machines, whirring busily but with no useful function, to structures that allude to the fundamental building blocks of the universe, Conrad Shawcross (born 1977) uses sculpture to explore the big ideas of philosophy and science. A graduate of the Ruskin School of Drawing and Fine Art and the Slade School of Art, he bacame the youngest living Royal Academician in 2013. This year – punctuated by a series of prestigious public sculptures – has been his busiest yet.

Quentin Blake, illustrator, cartoonist and children’s author, has, to date, illustrated over 300 books. He is most famously associated with Roald Dahl, but he’s worked with a number of children’s writers, most recently David Walliams, illustrating the actor's debut novel The Boy in the Dress. He is a patron of The Big Draw which aims to get people of all ages drawing throughout the UK, and of The Nightingale Project, a charity that puts art into hospitals. Since 2006, he's produced work for several hospitals and mental health centres in London and in France.

Things you might know about Oslo: it’s expensive and the cost of a beer, wine, dinner for two – whatever your tourist yardstick – might make your hair stand on end (the cost of living is currently second only to Singapore city, according to a 2014 survey by the Economist Intelligence Unit); it’s small (population: 600,000), yet it’s also the fastest growing capital in Europe, thanks to both overseas immigration and the fact that many Norwegians are now moving to the capital; its most celebrated son is, of course, Edvard Munch.

On a snowy day in early spring in New York, the On Kawara – Silence show at the Guggenheim is unlikely to warm you up. His date paintings, postcards, telegrams and other coldly ur-conceptual accountings spiral up those famous white Frank Lloyd Wright stairs, seemingly ad infinitum. But it’s a powerful, hypnotic experience, one that seeps into your subconscious and becomes a meditation on time and space.

Andrew Comben, CEO of the Brighton Festival, chooses ten locations that have resonance with the annual event. He talks about their past and future but, most particularly, what will be happening this May

“Brighton Festival is all about the spaces and people of the city,” he explains, “Some of these spaces are especially evocative. They make artists think about doing things in different ways and make audiences respond accordingly. We have to strategise, sometimes taking over places that are used for other things most of the time. It’s always an adventure.”

This is work that wears its heart on its sleeve. That’s what gets you in the end in this big retrospective of the work of Niki de Saint Phalle.

The sea is the theme uniting Simon Faithfull’s mid-career retrospective. It makes the port of Calais the perfect host for this splendid exhibition and, to put you in the mood, ideally you should make the crossing by boat. Faithfull spent six days going back and forth, back and forth on the P&O ferry between Dover and Calais. He passed the time – one and a half hours each way – sketching on his iPhone things that caught his eye, including a luggage trolley, a man reading (pictured below right), a waiting lifeboat, docking in Calais.

Russia’s national gallery, the Tretyakov, bears the name of its founder Pavel Tretyakov, the 19th-century merchant who bequeathed his huge collection of Russian art to the city of Moscow in 1892. His bust stands proudly overseeing the entrance to the gallery’s old building, a fine, purpose-built example of early Russian 20th-century architecture.

Artangel continues to instigate extraordinary events in extraordinary places. Over the past two decades and more, directors Michael Morris and James Lingwood have helped generate major and ground-breaking work by Rachel Whiteread, Brian Eno, Laurie Anderson, Roni Horn, Jeremy Deller, Steve McQueen, Matthew Barney, Gregor Schneider, Francis Alÿs and many others. It's a long list. Their latest collaboration with PJ Harvey is no less thought-provoking and inspiring than the best of their unique collection of imaginative and risk-taking projects. 

Whether you’re interested in buying, just looking or attending one of the many talks and events, the London Art Fair is the place to be over the next few days if you’re keen on modern and contemporary British art.
