Happy New Year!

The last few years I’ve made a calendar from photos taken through the year, to furnish homemade gifts to my close family. My brother clearly values this gift, and has it on proud display in his downstairs lavatory! This year, the power of blogging enables me to display such quality gifts to so many more people – a good two or three, at least.

The Inelegant Gardener (HappyMouffetard) is responsible for some of these, but I can’t remember which – probably some of the ones of flowers.

Cover image – it’s an amaryllis.
January – a brass marmot in the mountains above Obergurgl
February – a dwarf iris
March – a rice paper butterfly (at Chester Zoo)
April – more snowy mountains, this time Orelle in France
May – spring greenery in North Wales
June – calendula
July – Blea Tarn, above Great Langdale
August – the Japanese garden at Tatton Park
September – autumn colours in North Wales
October – jack o’lantern by HappyMouffetard, photography by me
November – fireworks in Val Thorens (cheating, because this was April)

December – frosted nigella seed head
Thank you for visiting the blog in the few short months since I started writing it, it’s been great fun and I’ve enjoyed reading your comments.
Happy New Year to you all!

What kind of scientist am I? (audio version)

My earlier “What kind of scientist am I?” post is now available as a podcast: http://bit.ly/6EA17H – Posterous allows the easy posting of audio. I’m not sure I’ll do it again but it was fun to try. I used a basic Logitech headset microphone, Audacity to do the capture and editing with the Lame plugin for MP3 export.

A walk along the Shropshire Union Canal

Yesterday the weather was so evil, cold and wet, that we scarcely left the house all day – cabin fever set in. This morning things were looking rather better, cold and frosty, but a little hazy – so we set off for a walk along the Shropshire Union Canal which passes close by. In the summer I cycled along the canal for a week, on my way to work, and saw a couple of kingfishers. No kingfishers today, but we saw a heron, a fox leaping through undergrowth and heard the distant roar of a lion at Chester Zoo.

Grant Applications II

This post is probably not for you, unless you’re interested in grant applications!

I touched on grant applications a few posts ago with reference to the THES debate on blue-skies research, I mentioned my abysmal grant application record, the generally low success rate and the pain involved for all concerned. Here I intend to add a few additional comments arising, in part, from my experience in industry.

It’s worth stating what I believe the grant application process is for: on the face of it is a method by which discretionary funding is provided to researchers to provide resources for research; that is to say equipment, consumables and personnel. However, in addition to this it has a hidden purpose in that it is felt by many to be part of an rating process for researchers. Researchers believe that the more grant applications they win, the higher their ranking. Therefore top-down attempts to limit the number of applications a researcher can make cause consternation because they impact on the perceived worth of that researcher. This additional function is not explicit, and in a way it arises for a lack of any better measure of apparent researcher worth.

I believe this perception arises because university departments don’t do a very good job of career management for academics. As an employee of a very large company, I have regular discussions about where my career within the company is going – indeed in my first year I spent about an hour and half talking about just this subject, whilst in academia I *never* in 8 years post-doctoral employment, had a formal discussion about my career development. This applies both to those who have successfully made it to permanent lecturing positions, and the many post-doctoral research assistants who aspire to a limited number of permanent posts.

The grant application process takes no account of an attempt to create a wider research program. Grant applications are made to acquire a specific piece of equipment and/or someone to carry out the research proposed. Typically the equipment will be used long after the end of the grant, and there will be no formal mechanism of replacement.

I am still involved in writing internal research proposals, these differ in two ways from grant applications. Firstly, they are much shorter than grant applications – a couple of sides of A4; secondly, they are much more concerned with all the things ‘around’ the core of the proposal rather than an explicit description of the research to be done. Funding and allocation of resources is made at the level of projects comprising of order 10 or more people, rather than at the 1 or 2 researcher level at which the typical grant application aims. Furthermore there is a longer cascade in the resource allocation process, rather than each ‘end user’ approaching the holder of a central pot, resources are allocated at a higher level. This reduces the number of people in the grant application business and means that rounds of allocation are smaller affairs.

The winning of grants appears to contain a large element of lottery, that is to say the outcome depends to a moderate degree on chance. To improve your chances of winning a lottery, you buy more tickets. This has caused the EPSRC, at least, problems since although the amount available for grants has increased, the amount applied for has increased more rapidly.

There are two solutions to the problem of researcher disillusionment through the low success rate of grant applications, one is to increase the amount of cash available (which is unlikely to happen in the current economic climate), the other is to reduce the number of grant applications made – here the problem is how to do this in an equitable fashion. Part of the problem here is that the number of potential researchers is governed by the number of people required to teach the undergraduates population, rather than a judgement on the number of people required to consume the research allocation pot.

So what does this suggest for the grant application process:
1. Better career management for academics, in order that the grant application process is not used as a rating tool for academics;
2. Devolution of spending to a lower level;
3. More thought paid to providing continuity.

I guess in my ideal world an academic will develop a coherent, over-arching research plan which is executed in pieces by application to research funds at something like the university scale. The success of such applications depends largely on past performance, and on the coherence or otherwise of the over-arching research plan rather than an attempt to evaluate the quality of a particular piece of research, or idea, in advance.

It’s worth noting that academic research is seriously difficult, in that your ideas should be globally competitive – you should be developing thoughts about how nature operates at that are unique. Your competition is thousands of other, very clever researchers spread across the world. Compared to this, my job as an industrial researcher is easier – I need to communicate the answer to the question at hand to the appropriate person, if the answer already exists then that’s fine. Also I get to do more research with my own hands than I would in an equivalent position as an academic.

What kind of scientist am I?

Following on from my earlier blog post on the tree of life, this post is about the taxonomy of my area of science: physics. I should point out now that I’m not too keen on the division science in this way. These divisions are relatively recent, as an example: the Cavendish Laboratory, the department of physics at Cambridge University, was only founded in 1874.

I am an experimental soft-matter physicist.

So taking the first word: experimental. This is one of the three great kingdoms of physics, the others being  computer simulation and the theory. “Experimental” means I spend a large part of my time trying to do actually experiments on objects in the real world, this may involve substantial computational work to process the output data and should generally involve some comparison to theory when published, although serious development of theory tends to end up in the hands of specialists. Computer simulation is distinct from from theory: simulation is like doing an experiment in a computer – give a set of entities some rules to live by and set them at it, measure results after some time. Theory on the other hand attempts to model the measurements without the fuss of explicitly modelling each entity in the collection.

Next to the physicist bit: In a sense theory is the essence of what physics is about: building an accurate model of the world. The important thing with physics is abstraction, to take an example I’m interested in granular materials; from a physics point of view this means I’m looking for a model that covers piles of ball bearings, avalanches, sand dunes, grain in silos, cereals in a box and possibly even mayonnaise all in a single framework.

And so to the final division: soft-matter. Physical Review Letters, which is the global house journal for physics, has the following subdivisions (in italics):

  • General Physics: Statistical and Quantum Mechanics, Quantum Information, etc; Domain of Schrödingers cat, Alice and Bob exchanging secure messages, and Bose-Einstein condensates.
  • Gravitation and Astrophysics; Physicists go large. Stephen Hawking lives here – black holes, the big bang.
  • Elementary Particles and Fields; down to the bottom, with things very small studied by things very large (like the Large Hadron Collider at CERN). Here be Prof Brian Cox.
  • Nuclear Physics; The properties of the atomic nucleus, including radioactivity, fission and fusion. This is Jim Al-Khalili‘s field. 
  • Atomic, Molecular, and Optical Physics; Stuff where single atoms and molecules are important, things like spectroscopy, fluorescence and luminescence go here.
  • Nonlinear Dynamics, Fluid Dynamics, Classical Optics, etc; Pendulums attached to pendulums, splashes and invisibility cloaks!
  • Plasma and Beam Physics; Matter in extreme conditions of temperature: fusion power goes here.
  • Condensed Matter: Structure, etc; Condensed matter is stuff which isn’t a gas – i.e. liquids and solids, and is acting in a reasonable size lump. 
  • Condensed Matter: Electronic Properties, etc; This is where your semiconductors, from which computer chips are made, live. 
  • Soft Matter, Biological, and Interdisciplinary Physics; Soft-matter refers to various squishy things, plastics, big stringy molecules in solution (polymers), little particles (colloids, like emulsion paint or mayonnaise), liquid crystals, and also granular materials (gravel, grain, sand and so forth).

So there I am in the last division, studying squishy things.

Since I’ve provided a means to wind up most sorts of scientist in previous blog posts, I thought I could provide a few here for me. Theoreticians can wind me up by assuming that experiments, and the analysis of the resulting data, are trivially easy to do and if they don’t fit their theory then I need to try again. Simulators I have a bit more sympathy with, simulations are experiments on a computer, however when you’re writing a paper perhaps you should say in the title you ran a simulation, rather than did a  proper experiment like a real man ;-)

Update: I made this post into a podcast: http://bit.ly/6EA17H – it’s on Posterous because uploading of audio is easier. I used a basic Logitech headset microphone, Audacity to do the capture and editing with the Lame plugin for MP3 export.  I’m not sure I’ll do it again but it was fun to try!
