Writer Susannah Leigh was born in Canada and moved to UK when she was eight years old. Jump! asked her about her favourite children’s book.
One of the nicest things about being an author (apart from being able to go to work in your pyjamas) is being invited to talk about books in schools. I love chatting to enthusiastic pupils about all things bookish. Usually the questions I am asked are ones I can answer easily.
‘How long does it take you write a book?’
‘Where do you get your ideas from?’
‘When did you write your first book?’
But at a school last week a student asked: ‘What is your favourite book?’
Now that’s a tough one.
I’ve read so many good books, how could I possibly choose my favourite?
And what if I haven’t read my favourite book yet? Indeed, what if it hasn’t even been written?
It has been reported that a computer program has passed the famous Turing Test by pretending to be a 13-year-old Ukrainian boy called Eugene Goostman. But just what is the Turing Test and why is this development so interesting? Sam investigates.
I bet you’ve heard some adults warn that too much screen time can damage your eyes. Some even say that sitting too close to a screen can be harmful. This is an idea that’s been around for decades but is there any truth to it?
In the latest of our Fact or Fable series, Sam investigates.
What can we tell from the study of BONES? According to Tina, we can tell an awful lot about a person by studying their bones – even centuries after they died. This process is called CARBON DATING.
Most scientists believe that the Universe began in a Big Bang around 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead, and was hotter and denser than anything we can imagine.
When the explosion called the Big Bang happened, the Universe as we know it was born. In a fraction of a second, the Universe grew from smaller than a single atom to larger than a galaxy. It kept on growing, and is still expanding today.
Now researchers in America think they have found traces left in the sky that prove this that the Big Bang did really happen. It takes the form of a distinctive twist in the oldest light detectable with telescopes. These twists of light are called ‘gravitational waves’ – the effect is a little bit like how waves form on the surface when you drop a big stone in a pond. However, you also have to imagine that the Big Bang formed the pond itself.
The team leading the project, known as BICEP2, has been using a telescope at the South Pole to make detailed observations of a small patch of sky. The aim was to find evidence of ‘inflation’ – the idea that the cosmos grew rapidly in its first trillionth, or trillionth of a trillionth of a second – growing from something unimaginably small to something about the size of a marble.
The leader of the team, Prof John Kovac of the Harvard-Smithsonian Center for Astrophysics said:
“This is opening a window on what we believe to be a new regime of physics – the physics of what happened in the first unbelievably tiny fraction of a second in the Universe.”
Over the coming years, scientists will work hard to investigate every aspect of this discovery. Other experiments will be carried out to see if they can replicate the findings of the American team. If this research is confirmed, it will be one of the greatest scientific discoveries of our time.
