Great Women You Should Know… Hedy Lamar
You probably do not know who the actor Hedy Lamarr was as her last film credit was in 1958. If you ask your parents they may have a vague recollection or at least know her name.
What they probably don’t realize is that she wasn’t only an actor. She was a philosopher and, most importantly this month as we remember the World Wars and the sacrifices made during those wars, she was an inventor. She and avant-garde composer George Antheil worked together to create the first broad-spectrum frequency hopping wireless communications.
“What on earth is that?”, you’re probably thinking!
Exploring Australia: Specsavers, Sunshine and Sexism
When I found out I was coming to Australia for two weeks, I was so excited. Australia’s completely the other side of the world to my home in Birmingham. I fantasised about what it would be like: kangaroos hopping round, koalas on every corner, barbecues every night. It would be so different to what I’m used to.
But when I got here, the first thing that struck me was how similar everything was. Getting the bus from the airport, I noticed they drive on the same side of the road as us. When I got to the bus station, the first shop I saw was a WH Smiths. In fact, lots of the shops are the same: Specsavers, Zara, Laura Ashley, Vodafone, Starbucks, McDonald’s, KFC. The first night I was here, I was truly adventurous and had tea at Nandos (although it wasn’t as nice as the ones in the UK and they didn’t have my favourite Wild Garlic and Herb sauce) and then went back to the hotel and watched Homes Under the Hammer, Time Team and Coronation Street.
Jump! Into SCIENCE – Dry Ice Bubble Experiment
Do you like blowing bubbles? Well, how would you feel if you could blow foggy bubbles that bounce? Pretty awesome, huh? Check out this fun dry ice bubble experiment.
A Day in the Life of… a Structural Engineer
You might be starting to think about which subjects you want to study at school, perhaps you have even had a talk about careers.
One thing that is quite tricky to assess is what a job is REALLY like. Some jobs are quite easy to imagine, such as working as a teacher, because we see the work that teachers do every day. Some jobs are a bit of a mystery. What does an engineer actually DO? And what do you have to study, to become one?
Today we are introducing a new series of articles, which will show you the typical working life of people in many different professions. If you know someone who has an interesting or unusual career, ask them if they would agree to a short interview with us to show kids a day in their life.
We were lucky enough to interview Tasha Scott, who was happy to explain to us her studies and career as a Structural Engineer.
A Kid-Friendly Explanation of The Big Bang & An Amazing New Discovery by Scientists
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.
