When I Met Mary Robinson – Written By You

Me and my mum went to hear this lady talk, her name is Mary Robinson, Mary was the President of Ireland, but she was not just any kind of President of Ireland,she was the first woman President of Ireland. She got a Presidential Medal of Freedom from President Obama in 2009. And was the first President of Ireland to visit the Queen.

Growing up

Mary grew up in a small town in Ireland, her mum and dad where doctors and her gran died when she was about 10 years old… When Mary was 17 she went to a finishing school in Paris while deciding if she wanted to become a nun… In that finishing school she was the only non-French speaking student there.

Mary Robinson famously put a light in her kitchen window to guide the people that have left Ireland to live a country abroad back home.

my question

If you had a chance of asking Mary Robinson a question in front of 600 people, would you do it? I would, and I did. Here’s what I said and what Mary replied:

Afterwards Mary signed a copy of her book for me

Who on Earth Invented Traffic Lights?!

Every day we use hundreds of inventions without even thinking about it. In this series, we’ll be celebrating some of the most overlooked inventions, finding out what inspired their inventors and maybe even a few unexpected tales along the way. Contributor Sally Anne asks… “Who on Earth invented… Traffic Lights?!”

Rock, Paper, Scissors… Robot???

The game rock-paper-scissors is well known around the world. We’ve all used it as a choosing method, or simply as a game! The easiest version is played between two people. Both players choose one of the three shapes for one of their hands, and reveal their choice at the same time, hoping their choice beats their opponent.

It’s nearly impossible to gain an advantage over your opponent, unless you wait long enough to identify their choice before you make yours, but the chances are that they will realise your cunning plan and call you a cheater!

This game is not simply a choosing game. There are mathematicians dedicated to constructing algorithms for the best strategy to win, and scientists devoted to creating unbeatable robots! In fact, researchers at the University of Tokyo have created a rock paper scissors robot that wins at rock-paper-scissors 100% of the time.

Get Cracking With Computer Coding for Kids

Kids computing – there’s a lot of talk going on about it right now. What do you learn about computing in your school? Are they teaching you how to make cool video games? How to come up with a story that makes sense, how to make sure that it’s engaging, that there are challenges at each level, and that there’s a reward at the end? How to build that?

How to make the bird you toss flop realistically into a pile of whatever you choose – making sure that gravity works the way you would expect it to (or not). How to craft the graphics you need to tell your story? How to publish that to your own smartphone and to share it (or sell it!) to friends and strangers?

Hmmm, I didn’t think so. “ I’d rather just do some Power Point and Word exercises, “ said no kid, ever.

A Trip to Mars!

Imagine being able to catch a flight to Mars as easily as we travel to another country – that was the idea behind the Trip To Mars session I attended at the Cheltenham Science Festival. It was conducted by Dr Suze Kundu and Dr Simon Foster and presented as a pre-flight safety briefing, with both of them dressed as pilots! There were a lot of humorous moments and sci-fi references but also some great science.

Suze and Simon suggested that in the future, flights to Mars could be far quicker than they are now, and explored how some of the bigger problems could be overcome. For example, the Sun’s magnetic field deflects a significant proportion of the cosmic radiation that could be harmful to humans on Earth; as spaceships travel further away from the Earth and Sun they will have less protection because the magnetic field weakens. To combat this it’s possible that spaceships will contain or be covered with large and powerful magnets, to produce the same deflective effect. This would have the added advantage of also deflecting radiation from solar flares.

Spaceships journeying to Mars would travel at such speed that even tiny fragments of rock and dust could be damaging to the hull. To combat this, and also the heat generated when the spaceship passes through an atmosphere, Suze and Simon discussed the possibility of spaceships being coated in aerogel. This amazing material is a solid formed from silicone dioxide but is 98% air; this means that it is extremely light but also strong. Its melting point is 1,200°C (equivalent to asbestos) and it is a wonderful insulator. Because it consists of large pockets of air between thin layers of silicone dioxide, any dust or rock fragments that hit it would be slowed and stopped before they could penetrate the aerogel completely.

Suze and Simon also discussed the possibilities and problems with cryostasis. Theoretically this is when a person’s body is cooled to temperatures so low that they enter hibernation, ideal for long journeys through space. Unfortunately our technology isn’t advanced enough to do this at the moment; any attempt would result in the cells rupturing and the person dying. But in the future it will be possible, perhaps after the person’s DNA has been altered slightly so that they can produce antifreeze proteins like some species of wasps and turtles.
