Making Sense of Science

Madeline_BurkeMadeline Burke is a third-year postgraduate researcher in the department of Cellular and Molecular Medicine.  Madeline did her undergraduate degree in Mechanical Engineering before switching disciplines when she started a PhD with the Bristol Centre for Functional Nanomaterials (BCFN). She is currently building a 3D bio-printer that can create human tissue by printing stem cells. Madeline’s research is interdisciplinary, using concepts from chemistry, cell biology and engineering, to design matrices for stem cells that not only support the cells, but cause them to grow into desired tissue such as cartilage. Most of her time is spent in the lab, designing new experiments and building her 3D printer.

As a PhD student I’m always worrying. I worry that I’m not doing enough work, that I should be getting in earlier, that I should be working “smarter”, that my experiments aren’t working, that I must be doing something wrong because they should be working by now…you get the point.

Sometime during my first year I thought to myself ‘there must be other researchers out there who are worrying about the same things that I do’. Like all good researchers who don’t know the answer to a question I turned to Google to see if I was right, if there were other students out there who were worrying as much as I was about everything PhD related. Much to my relief I came across a whole host of blogs dedicated to people that felt exactly the same as I did! PhD students who weren’t sure research was for them, students who loved researching but had an unshakeable feeling that they weren’t good enough, students who were questioning why they were doing a PhD.

It was an amazing feeling – I wasn’t alone! Other people were having the same problems as me, but even better, they had advice for how to deal with these problems. I found one blog dedicated to writing a thesis in three months, I found another on how to deal with a difficult supervisor (not that my supervisor is difficult I would like to point out!) and another on finding jobs outside research after your PhD has ended. I found more blogs then I could mention, written by struggling PhD students on their experiences in research and academia. These blogs all helped me to make more sense of my PhD. I could relate to what other people wrote and look up ways of coping with PhD stress and expectation. I started to realise that sometimes I enjoyed reading these blogs more than I enjoyed my PhD, but still I did nothing about these feelings – I just got on with my research while moaning to everyone around me who would listen.

After going through a particularly bad spell of results a few weeks ago and really questioning whether this was what I wanted to do with my life, a friend approached me and told me about a media course run by Sense about Science, a London based charity whose aim is to equip people to make sense of science and evidence. I have been on a few media courses before, including one very enjoyable course run by Imperial, but this was different.

We got to quiz a panel made up of both researchers and journalists on their experiences with science and the media, including (to name a few) an assistant news editor at Nature, an Infectious Disease Epidemiologist in the World Health Organisation and a freelance journalist who writes about the science behind the beauty industry. We were told not to be afraid of the media when it comes to our research – by doing a PhD we will automatically know more than most people about our fields and we shouldn’t be afraid of using the media to promote our research. A valid point. I, for one, would worry that my opinion was not ‘expert’ enough. The panel also advised having three points and sticking to them – even if that’s not what they have asked you – a good point for any form of communication, really. I left wondering if that would work in a viva!

The journalists shared how they put a story together, including what they would need from scientists. For example, they need someone who would be readily available to give a quote and that the quote would be easy to understand. Finally, the day was rounded off with a Research Media Officer giving us some tips on how to get involved in science communication. One of the common themes of the day was to get involved and make your voice heard. We were told unequivocally to join Twitter and another piece of advice I really took to heart was to start a blog. I had toyed with the idea before but the Voice of Young Science media workshop really gave me the push I needed to get started.

The internet is such a powerful tool, so use it! How can you get your voice heard? How can you motivate yourself when you research just isn’t working? What if academia just isn’t for you? There are loads of websites out there answering these questions, just start Googling.

Flowchart

What are the differences between sciences and engineering? Not an earth shattering, life changing question, I’ll admit, but one I have been pondering recently after my foray into nanoscience. Having previously defined myself as an engineer, a PhD in nanoscience has made me challenge my views and definition of science as a subject. Cheesy I know, but seriously, the differences between my engineering student university experience and that of my science graduate colleagues were astounding to me. So I decided to try and define these differences and where better to start answering my questions than the oracle of all things known (also known as Google or in this case my first hit, Wiki answers).

Wiki answers says “A scientist is a person who has scientific training or who works in the sciences. An engineer is someone who is trained as an engineer.” Somehow I don’t think it is that simple. As I’ve found out there is a huge amount of overlap between science and engineering, especially nanoscience. Let me explain – engineering is essentially applying scientific principles to real world problems, a product or solution is created and the problem is solved (or so engineers like to think). Science looks at the world around us and tries to find answers to its mysteries. The difference is not about the knowledge needed to study or practise these disciplines, but in the questions you ask.

In essence, a scientist looks at something and wants to understand “why?” Why is the sky blue? Why do things behave differently on the macro and micro scale? Why do stem cells proliferate and other cells do not? Essentially, it is about understanding and acquiring new knowledge. Engineering is more about “how?” As an engineer, I ask how I can make other cells differentiate. How can I sequence DNA cheaply and accurately? How can I make computers better, smaller and cheaper? Engineering is about invention and solving real-world problems rather than acquiring new knowledge.

This is where the hot new subject of nanoscience comes in, bridging the proverbial gap between science and engineering. Nanoscientists ask both types of questions: why do things behave differently at the nanoscale, and how can I apply this to a real world problem?

But I suppose the big question is who cares? Should there be a distinction between science and engineering? I highlight the well-known case of the chicken and the egg: in school, we were taught that science came first and engineering was the application of science, but now important advances in nanoscience are usually the result of a new tool becoming available. You could say that nanoscience is driven by engineering advances.

Nanoscience is starting to address the distinctions between engineering and science, and also within science itself. Coming from an engineering background the “why?” of science was a shock to me, but I’ve come to see it as an advantage. Engineering is often money and product focused, but without the why of science it wouldn’t exist. I still have the odd “how are you ever going to apply that to anything useful?” moment but in general nanoscience is perfect for me. I get the why and the how!

Dumb and Dumber

One of the hardest things I’m finding about my PhD is the constant feeling of stupidity overwhelming me at every turn. All the way through school and my undergraduate degree there was a huge importance placed on getting things right; getting the right answer to a question, understanding theory, reciting facts. The set of skills you worked so hard to acquire during school and your undergrad are almost entirely useless when doing a research degree, when something isn’t working you can’t just look the answer up in a text book.

This hit me the hardest recently when I asked the longest-serving postdoc in my group, who to me is the fountain of all knowledge, to help me with a problem I was having. Her answer, that she didn’t know how to solve the problem, astounded me. I asked around the group, no one knew the answer. If this group of highly intelligent people, who had worked in this field for many more years than I had, didn’t know the answer what hope did I have at succeeding? I went home feeling really dejected – why was I putting myself through this when someone who was far more experienced than me didn’t have the answer to one of my smaller research problems. Then I realised, that is the point of a research degree. No one knows the answer, it’s uncharted territory. I am working on a completely new research problem; it’s up to me to find the answer to my own question.

It took me a while, but after I accepted that no one knew the answer it suddenly became a whole lot easier. A couple of days of wading through papers and trying different things yielded a promising result and I realised that I’m not stupid, but that feeling stupid had helped to motivate me to find the answer. Stupidity and ignorance are feelings that most of us will feel throughout our PhDs. Initially I thought this was a bad thing – who wants to feel dumb all the time? But is feeling stupid really a bad thing? Maybe it’s the reason we strive harder to reach the next goal. The person that sums this up the best is Martin A. Schwartz who in 2008 wrote an essay in the Journal of Cell Science about “The Importance of Stupidity in Scientific Research”.

In his closing paragraph he reasons the importance of being productively stupid;

Productive stupidity means being ignorant by choice. Focusing on important questions puts us in the awkward position of being ignorant. One of the beautiful things about science is that it allows us to bumble along, getting it wrong time after time, and feel perfectly fine as long as we learn something each time. No doubt, this can be difficult for students who are accustomed to getting the answers right. No doubt, reasonable levels of confidence and emotional resilience help, but I think scientific education might do more to ease what is a very big transition: from learning what other people once discovered to making your own discoveries. The more comfortable we become with being stupid, the deeper we will wade into the unknown and the more likely we are to make big discoveries.”

I’m very lucky, having completed an undergraduate degree in engineering I have been schooled in creativity, problem solving and iterative understanding. Engineering takes known and clearly understood facts and applies them to a problem to solve it; this is essentially what we are doing in a scientific research degree. Taking the knowledge we know and using it to explore the unknown research problem. The feelings of stupidity I experienced in my engineering degree – not knowing if the filter I built using denim instead of expensive filter paper would work – I still feel today. In this case my ignorance worked, I discovered a much cheaper filter material, and my design worked. But more often than not the experiments you design don’t work, and the feeling of ignorance and stupidity persists. But hard as it is, I am trying to embrace that feeling. I don’t know the answers to all my questions, and maybe never will, but I’m definitely going try and find out.
