Bad Science and the Scientific Method - Southampton talk at Cafe Scientifique

Bad Science - the method, the media and the message

18th September 2008, 7pm, Meeting: Cafe Scientifique, Soul Cellar, 78 West Marlands, Southampton, SO14 7FW. Map.

The science Café will consist of a short talk (20-30 minutes) followed by a discussion—everyone is invited to ask questions, raise issues and discuss the science presented in an informal and friendly atmosphere. The Science Café is free and no booking is necessary. For more information please contact: Dr Christian Kaiser, Science Café Co-ordinator Tel: 023 8059 2073, email crk@soton.ac.uk

Dr. Phil Uttley, School of Physics and Astronomy, University of Southampton

One of the most important things science has given us is the scientific method itself, which since its first rigorous application in the 16th and 17th centuries has pushed our understanding of the universe and our place in it to previously unimaginable levels. And yet, the majority of the population are completely unaware of these simple principles which underpin human progress.
Much of this ignorance is down to the bad reporting and presentation of science by the media, which tends to portray science as arcane information handed down from on high, not a path to knowledge which most people can tread. At worst, the media actively pushes stories as `science' when they are really based on pseudoscience or a basic misinterpretation of scientific data.

In this talk, I'll use examples from science and the media to take a look at some aspects of the scientific method, how we can use them to make sense of the world, and show how without them, we can all be led astray.

We'll see how our unscientific ways of thinking may have been useful in the past when we lived as hunter-gatherers, but are really holding us back today.
On the way we'll look at cloud-creatures and nun-buns, the connection between superstitious pigeons and stock-market analysts, and I'll also point the finger at some less-than-obvious culprits in the bad-science wars.
Most importantly, I want to show how the scientific method is relevant to our daily lives and not just the classroom or laboratory.

Southampton Science Cafe, 21st February

Dear All,

I cannot really believe that it's already time for the next Café event, but in only a week's time we have Jim Thurston of the King's College Hospital in London leading a session on 'Is a little bit of Polonium good for you? - Current Issues in Radiation Protection'.

We meet on the 21st of February at 7pm in the Soul Cellar, 78 West Marlands, near the Civic Centre (see the map at www.astro.soton.ac.uk/~crk/scicaf/Img/location_dot.tiff

As usual, feel free to advertise to friends, colleagues, etc.

Best wishes,

Christian.

Is a little bit of Polonium good for you? - Current Issues in Radiation Protection 21st February 2008, 7pm

Every one of us will almost certainly be deliberately exposed to ionising radiation several times during our lifetime, especially for medical or dental diagnosis or treatment. We are also exposed to natural background radiation all the time. The deliberate use of ionising radiation for medical and other purposes has been going on for over 100 years now, and the public perception of the risks resultant from such exposure has changed quite dramatically during that time. However recent events have brought the attention of the public back to considering the potential harm of ionising radiation, such events including the Litvinenko Affair, Terrorism and Dirty Bombs, a return to Nuclear Power, etc.

This talk will give a historical background to the uses of ionising radiation, discuss some of the recent issues in the public domain, and also introduce some of the latest thinking on the actual hazards and risks of exposure to ionising radiation.

Large Hadron Collider - Southampton Cafe Scientifique















I attended a talk by Prof. Nick Evans at Southampton Cafe Scientifique on 24th January. He talked entertainly and in simple terms about the Large Hadron Collider (LHC) (wiki) coming into operation in May 2008 at CERN Switzerland. The talk was well attended with 80+ persons.

Prof. Nick Evans, School of Physics and Astronomy, University of Southampton

Cafe Scientifique say 'In just a few months particle physicists will be switching on a multi-billion pound atom smasher in Geneva called the Large Hadron Collider. This machine will probe the most basic building blocks of nature and shed light on our understanding of the masses of particles. Excitingly, the machine must uncover the explanation to a missing piece in our understanding of the weak nuclear force. Speculation is rife as to what will be found from the mysterious Higgs particle to "supersymmetry" or extra dimensions of Space-Time.'


The main points that he presented were:-
  • detecting the Higgs Boson is the main aim of LHC
  • LHC costs $2.6 billion over 10 years - this is comparitively a small amount of money
  • LHC will probe the nature of matter by firing hadrons (eg protons) into each other at speeds approaching speed of light with 14TeV 'smashability'
  • we humans see a 4 Dimensional world - if hadrons at LHC collide and some of the energy of collision is not accounted for - then maybe the energy has gone to another dimension (String Theory predicts 11 dimensions)
    • LHC is unlikely to give experimental support to String Theory (cf. Lisa Randall)
  • all matter is composed of 3 fundamental particles: electrons, up quarks, down quarks
  • a proton contains 2 up quarks and one down quark
  • a neutron contains 2 down quarks and one up quark
  • electrons v electron neutrino
  • he successfully resisted the temptation to delve into detail!
  • he only mentioned his book twice, en passant!
  • his (tongue in cheek) goal is to get a Nobel Prize!
  • we could be in for some surprises at LHC!!
  • whatever happens LHC will get some results
    • LHC is expected to be able to confirm or deny the existence of the Higgs boson in most circumstances.
