The Current War review – lacks the spark of invention

★★★ THE CURRENT WAR Benedict Cumberbatch and Michael Shannon battle to light up America

Benedict Cumberbatch and Michael Shannon in the battle to light up America

We like to think of scientists and inventors as innocent dreamers, trampled upon by the cruel old world. Of course, that’s not wholly true. Just look at today’s tech and social media industries. In fact the man cited as America’s greatest ever inventor, Thomas Edison, was a real scoundrel who wasn’t adverse to using dirty tricks to get ahead.

The Day We Walked on the Moon, ITV review - it was 50 years ago to the day

★★★ THE DAY WE WALKED ON THE MOON, ITV It was 50 years ago to the day

You've heard it all before, but this was an entertaining ride

It was on 16 July 1969 that Apollo 11 lifted off from Florida en route for the Moon, and exactly 50 years later, as we nervously anticipate the dawn of commercial flights into space, the event resonates louder than ever. Here, Professor Brian Cox called it “the greatest achievement in the history of civilisation.” According to veteran broadcaster Sir Trevor McDonald, it was “the most magnificent thing that ever happened.”

★★★★ INSIDE THE SOCIAL NETWORK: FACEBOOK'S DIFFICULT YEAR, BBC TWO How big can it get?

A force for good or Big Brother in the making?

Not everybody is on Facebook, yet. So far, Mark Zuckerberg’s social media monolith has only managed to scrape together about 2.3 billion users, roughly one-third of the planet. But as this fascinating documentary revealed, Facebook’s plans are huge and its ambitions boundless.

The Planets, Series Finale, BBC Two review - ice cold on Neptune

★★★ THE PLANETS, SERIES FINALE, BBC TWO Ice cold on Neptune

Brian Cox's series concludes with a deep-frozen trip to the far end of the Solar System

As an aid to meditation, Professor Brian Cox’s latest series The Planets (BBC Two) could hardly be faulted. A majestic tour of the Solar System awash with computerised imagery, an eerie soundtrack and a travel budget the president of the United States might envy, it exerted a narcotic allure as Cox’s gaze roamed billions of kilometres into deep space. His whispery commentary is a bit like having a scalp massage.

The Planets, BBC Two review - boy-band boffin rides again

★★★ THE PLANETS, BBC TWO Boy-band boffin rides again

Professor Cox hosts a spectacular tour of the mysteries of our solar system

Professor Brian Cox, still looking cheekily boy-band-ish at the age of 51, has made himself a child of the universe. His day job is professor of particle physics at Manchester University, but turn him loose with a camera crew and an unfeasibly large budget and he turns into a starry-eyed cosmic hippy.

Frans de Waal: Mama's Last Hug review - animal feelings

★★★★★ FRANS DE WAAL: MAMA'S LAST HUG Enlightening insight into animals' emotional, social worlds

Enlightening insight into animals' emotional and social worlds

Primatologist, ethologist, zoologist, biologist, social psychologist, behaviourist – how may ‘ists’ can one person have? Dutch-American scientist Frans de Waal has helped revolutionise how we think about the attributes of fellow animals. He writes for the lay reader without condescension, mixing anecdote with plenty of citations from controlled experiments.

Science Fair review - big on ambition, light on rigour

Engaging but somewhat slight doc on the world's biggest youth science contest

More than 1,700 teenage finalists representing 78 countries take part in the annual International Science and Engineering Fair, virtually the Oscars for exceptional young biologists, physicists, chemists, mathematicians, computer scientists, doctors and more.

If they’re selected for ISEF, these young brainboxes get to show the fair’s forbidding judges what contributions they’re planning to make to our futures – and compete with each other to be named best in show. It’s a remarkable (and, as the contestants point out, very American) event, and an even more remarkable gathering of young people – certainly as pictured filling a cavernous Los Angeles conference centre in this engaging, affectionate documentary from Cristina Costantini and Darren Foster.

Science FairThe directors focus on a clutch of aspiring young international hopefuls, each covered in a brief thumbnail portrait. Outgoing Anjali from Kentucky, who has a project for detecting arsenic in drinking water, is aware that personality and presentation skills are just as important as scientific insight at ISEF. From the same school, the laid-back trio of Ryan, Harsha and Abraham are working on an AI project to collate stethoscope data online. German teenager Ivo has come up with a prototype flying wing aircraft, and slacker Robbie from West Virginia – who taught a computer to rap like Kanye West – has a head-spinning scheme to track how machine learning actually works, using (what else?) machine leaning. Coming from an impoverished background in rural Brazil, Myllena and Gabriel (pictured above) provide a striking contrast with their US and European co-competitors, and their project aims to prevent the spread of the Zika virus.

That much we learn in Science Fair’s lengthy first act. The film then follows a well-trodden route: to take us through the teenagers’ struggles to be selected for the fair, then the tribulations of ISEF’s rigorous judging, and ultimately, the big reveal of the competition’s all-important results.

Parallels with the 2002 movie Spellbound – which follows the fortunes of eight young competitors at the 1999 US National Spelling Bee – are inevitable, and indeed the directors specifically namecheck Jeffrey Blitz’s earlier film as an inspiration. But there’s a big difference here. Almost anyone can grasp what goes into spelling a word correctly, but few of us will readily understand the complexities of these kids’ sometimes esoteric scientific research. (One of the contestants even jokes that the more incomprehensible your fair’s submission title, the more hardcore the work must be.) Even the fair’s own set-up hardly lends itself to film treatment, not least because the all-important final judging takes place behind firmly locked doors.

So bringing ISEF alive is a tricky prospect – one that Costantini and Foster achieve marvellously in terms of personality and ambition, but less so in hardcore scientific detail. Even with their lively subjects, however, there are simply too many for us to feel like we get to know them in much depth. When the fair’s overall winner is announced – and yes, spoiler alert, it’s one of the kids Costantini and Foster feature – we hardly know them, nor, more importantly, properly understand the significance of their project.

Science Fair is an inspirational portrait of young ambition, commitment and resilience, and its directors gain remarkably close access to the kids featured, following them closely across several months. But by not properly understanding these budding scientists’ projects, it feels like the audience is kept at quite a distance. It’s rather ironic – and frustrating – that while celebrating the unapologetically complex insights of these youngsters, Science Fair itself seems content skate on the surface of their achievements.

Square Rounds, Finborough Theatre review - the science behind warfare, told in verse

★★★ SQUARE ROUNDS, FINBOROUGH THEATRE Didactic theatre piece stronger on facts than drama

Didactic theatre piece stronger on facts than drama

The title of Tony Harrison's teacherly entertainment – it can't be called a play – refers to the square bullets invented by James Puckle to kill Muslims in the 18th century. This shocking morsel of information is provided by the brothers Hiram and Hudson Maxim, inventors respectively of the machine gun and smokeless gunpowder, who are two of the characters in Square Rounds.

Genesis Inc, Hampstead Theatre review - Harry Enfield in ungodly mess

★★ GENESIS INC, HAMPSTEAD THEATRE Harry Enfield in ungodly mess

Huge new play about the fertility industry is rather crudely conceived

We are now pretty familiar with the idea that human reproduction (making babies) has been turned into big business, and there have already been several good recent plays about desperate couples and surrogacy – Vivienne Franzmann’s Bodies and Satinder Chohan’s Made in India – so is there any more to be said about giving nature a helping hand? This Hampstead Theatre certainly thinks so.
