You May Not Believe This But ...? 3 Interesting Talks To While An Evening Away
In this age of “fake” news, I have done some work on the difference between something being true in a sense which is based on our best knowledge, or merely plausible. This is not a serious analysis, but I shall present three lectures of an amusing content, richly illustrated, which could be ...?

Biosignatures in Earth's Oldest Sediments
Tracing evidence for the oldest life on Earth, and Mars?

The oldest sedimentary rocks on Earth preserve a record of early biological evolution that might also have occurred on early Mars. We routinely image compositions of key minerals that represent the remains of microbial biomass, which provides information about the origin of graphitic carbon in the oldest metamorphosed sedimentary rocks. We are now testing a new model involving chemically-oscillating reactions in the formation of concretions on Earth as an approach to search for the remains of extra-terrestrial life in such structures, known to occur on Mars.

The History of Local Anaesthesia
Most equate ‘anaesthesia’ with general anaesthesia. This is likely because the introduction of general anaesthesia (1846) predated that of local anaesthesia (1884). The drugs used for these first demonstrations, ether and cocaine, had been in existence for centuries before pioneers made the mental leap between the knowledge that they could cause – respectively – sedation and numbness, and the potential for these effects to be used for the benefit of mankind.
This lecture maps the progress of cocaine from a drug of use and abuse by native South Americans first recorded by the Spanish conquistadors, through its use as a tonic in the 19th Century – it gave its name to Coke™ – to the discovery of its anaesthetic properties. Many had the opportunity to make the link between the numbing effects of cocaine and its medical potential, but it was not until 1884 that two young doctors in Vienna (Sigmund Freud – the Father of Psychoanalysis – and Carl Koller – the Father of Local Anaesthesia) made the mental leap that ushered in a revolution in medicine.
Pausing briefly to draw the audience into diversions such as the key role of the Austrian navy in the history of cocaine and the problems that medical pioneers experienced when experimenting with addictive drugs, Dr Harrop-Griffiths will put a humorous spin on a fascinating story.

Origin, Evolution and Extinction of the Dinosaurs
*** CANCELLED *** and replaced by

The Myth of the Pack-Hunting Dinosaurs
and associated fallacies of Dinosaurology

The idea that some carnivorous dinosaurs hunted in packs is well established in the popular imagination thanks to the phenomenal success of the 'Jurassic Park' movies. Mike Howgate will explain how Professor John Ostrom's misinterpretation of the fossil evidence excavated by the Yale Peabody Museum in the 1960's launched the intelligent, warm blooded, hyperactive, pack-hunting 'RAPTORS' and why his theories are in need of a thorough rethink.

A Map of the Invisible
Smashing Physics: Journeys to the energy frontier
Exploration of the very smallest constituents of nature reveals a strange landscape, where quantum fields abound, particles aren't all they seem, and symmetries rule but can be broken. Prof. Butterworth will take a quick tour through some of this landscape, focussing on the latest particle to be discovered – the Higgs boson – and the explorations currently taking place at CERN with the Large Hadron Collider.
Prof. Jonathan Butterworth
(University College London)

Spider Silks and Webs
Spiders are everywhere and though some people may fear them, their webs and silks have been objects of human fascination for millennia. This talk will serve as an introduction to the wonderful world of spiders and the silks they spin, as well as some of the potential applications and technological advances made possible from the study and use of silks.
