Printing Ourselves a Better Life

Recently, I have been seeing a lot of articles in newspapers, magazines and even on the television, glorifying 3-D printing. It seems to have popped up almost out of nowhere and taken the world by storm.  I have come across reports of footwear, jewellery, guns and even prosthetic limbs being created by this new wave of technology. I had to know more.

In simple terms a 3-D printer is like the ink printers we all know and use. We send an electronic file to the machine, the machine starts spiting out ink on the desired spots as described in the electronic file, Ta Dah! We have a printed page. The 3-D printers that are commercially available follow the same basic idea only instead of spitting out ink at a piece of paper, it spits out polymers in layers that are fused using UV lasers. Simple.

The possibilities for 3-D printing are endless. Already it has proved life changing to many industries as well as individual people. I came across article that talks of how NASA has used the new technology to email, yes email, a wrench to the international space station. Thus saving weeks, months or possibly even years by not needing a rocket to be sent up.

While scouring the internet for more details, I stumbled across a heart warming story of an adorable dog named Derby, who was born with malformed front legs. His foster family sought help from scientists, who create new limbs for him using 3-D printing. I have attached the video and I highly recommend watching it.

Technology advances at such a rapid rate in this day and age. If this is where we are at now, printing things from every day items to life changing equipment, the future can only be brighter.

Web of Mayhem

With the first assignment now out of the way, it is time to sit back and relax! Just kidding, its straight into assignment two. This assignment involves working in groups which I would usually be ecstatic about but as we are all distance learners, organisation is going to be difficult to say the least. I am glad that I have a friendly group to work with though, two of my fellow classmates came over for a bit of a meet and greet.


After meeting the girls, I realised how different our reasons for studying this particular paper are. The diversity in our set goals range from phycology to sports and even computing.


When I think of science, I have a very narrow mind. My mind trends towards lab coats and test tubes, big machines and long complicated reports. It often surprises me how vast the subject really is.


Not only is the subject of science a web of interlocking mayhem, everyone has a different take on it. While we are all doing our chosen field of science for a different purpose, there is still a common theme. Whether it be to better care for our surroundings, or to hack into the governments computers we all see science as a way forward.


From my own personal experience, having worked in laboratories for 6 years, the industry as whole is being slingshot forward. Technology is constantly upgrading, ideas and techniques are multiplying but the one thing that remains universal is the need for communication. Without communication we get left behind and at the rate the world is moving, one slip up and you fall into a black hole of return.


And on that note, it is time to get back to work before my boss catapults me into a black hole of her own...

Time to get Opinionated

For my position paper, I have the task of trying to sway my readers into agreeing with my point of view. I was given a list of topics, from which I decided on; All drinking water in NZ should be fluoridated. It seemed like a simple enough task, there has been a heated debate about the pros and cons for years now. Surely I could just pick a side and roll with it, fake it till you make it kind of thing. Man, was I wrong!

There are so many papers and journal articles out there telling us that if we fluoridate our communal water supplies, we will see an increase in dental health. As we are only human, we of course ask what the cost is going to be, or more to the point, which costs less? After reading several articles claiming that the prevention of dental decay (by means of adding fluoride to a communities water supply) is more cost effective than the treatment of dental decay, I found some useful figures based on a scheme in Quebec; for every $1 invested in the scheme, up to $82.83 could be saved in dental costs (Tchouaket, Broussell, Frasi, Dionne, Bertrad & Fortin, 2013). That would be a fairly good incentive for local governments to take action, think of how many extra biscuits could be supplied at meetings with each $83 spared!

Sounds great doesn't it? Everything looks good from a certain angle. If we take a hop, skip and a jump to the other side of the spectrum, there are also a lot of papers and journal articles saying that the dental rewards do not out weigh the hidden dangers. For instance, one article I read, using rats as test subjects, found that the World Health Organisation's recommended dosage can be nephrotoxic (Martin-Pardillos, Sosa, Millan & Sorribas, 2014). Cure one problem but cause another. Using big words that sound scary, like "nephrotoxic", this article encouraged me to swap my crystal clear tap water for a dirty brown ale from a slightly different tap.

With arguments both for and against the fluoridation of water, its been very eye opening for me and only made me delve deeper into the nitty gritty details.
