I’m currently in the midst of producing a 30 minute radio piece on the subject of death. To be more specific, I’m exploring contemporary attitudes towards death and doing so through the perspective of those who deal with death on a daily basis.
Part of my project took me to the basement of the Royal Sunderland Hospital where I spent the day exploring it’s mortuary with pathologist Dr Stuart Hamilton. Recently, as I was listening back to his interview I begun to find myself fixated on a particular section, in which he discusses the way in which he views the human body. He describes his view of life as being very ‘mechanistic’ and as I listened to him talk about the body as ‘pumps’ and ‘shunts’ I was inspired to compose a short piece from his words.
As a biologist myself, I have always considered the human body to represent a beautiful feat of natural engineering. From the minute intricacies of the inner ear to the extent of the circulatory system, pulsating to the rhythm of a beating heart – the human body is living machine. Our consciousness and everything that makes us, ‘us’ is a product of this machinery and when the machine stops – so do we.
The title of this piece toys with the idea of Adam and Eve and how this throws up a very different view of the human body. However which ever view you take, both are unified in the fact that they find certain beauty in the human form.
Soundcloud’s audio compression has reduced the quality of the piece somewhat so please get in touch if you’d like a copy of the original file.
I’m posting two little audio pieces to mark the end of NASAs space shuttle program which will (with any luck) enter its final mission today with the launch of Atlantis (STS-135) in a few hours.
The first was produced for the latest Imperial College I,Science podcast and features science writer and producer Piers Bizony speaking on the history of the space shuttle program at a Super/Collider event in May.
The Second is a short piece extracted from the first, imagining what it might sound like to be inside the shuttle during take-off. The radio chatter you hear comes from Columbia (STS-1), the very first shuttle launch which blasted off over 30 years ago on 12th April 1981. The eventual winding down towards the end symbolises the ending of the project’s 30 year run.
The BBC has produced an excellent interactive history of the space shuttle program here and a friend from my course has also written an excellent article on the future of manned spaced flight here
So most of our universe (over 70%) is made up of something called Dark Energy. We can’t see it and we don’t really know what it is…
Matter – everything that makes up me, you, planets and stars – appears to make up only a very small fraction of the universe, about 4%. Instead, the universe seems to be filled predominantly by a very strange material known as dark energy and it is this material, with it’s anti-gravity properties, which seems to speeding up the expansion of our universe. We’ve known that the universe was expanding since Edwin Hubble made his observations in the 1920s, however it’s only in the last 20 years that we’ve realised that this expansion is actually speeding up! The problem is that we can’t directly detect dark energy and this makes it very difficult to understand what it is and whether it really does exist.
Instead we must rely on indirect observations, looking at light travelling from the far reaches of the universe to determine whether the properties of this light has changed during the time it has taken to reach us. A good way to measure the expanding universe is to make observations of distant supernovae (huge explosions which follow the death of large stars) which act as ‘standard candles‘ or ‘lighthouses’ because we know how bright these object should be. Measuring light from distant supernovae has allowed us to see that it is different to what it should be if these objects were positioned within a static universe. Instead what we see is changes in this light which indicates that these objects are being flung outwards and away from us via some sort of cosmic expansion.
A nice analogy to describe the expansion of the universe is what happens when two points are drawn on the surface of an inflating balloon. As the balloon is inflated, the two points begin to move further and further away from each other and as the material expands outwards, the distance between the two points also increases. Applying this analogy to the cosmos, we could imagine the same happening with two galaxies being pulled apart from each other as the space they exist in expands.
As dark energy is so difficult to detect, scientists have recently been looking for new ways to independently verify its presence within the universe. Whilst at the BBC I was lucky enough to interview cosmologist Dr Chris Blake from Swinburne University, Australia who has recently published two papers reconfirming dark energy via a new set of methods. Blake and his colleagues produced a galaxy map of over 200,000 galaxies and used this information to look at how these galaxies were distributed and how they grew relative to each other. Through this work Blake and his colleagues were able to reconfirm the presence of dark energy and perhaps most importantly were able to determine some of its properties.
I thought I’d use the audio from this telephone interview and spruce it for the next sounds of science episode:
It probably sounds better with headphones (or obviously decent speakers).
