9:30am – 12:00pm Earth’s First Crust (ELSI 2 Lounge)
The First Crust Aftershop is designed to allow people to discuss this topic in more detail than is possible during the symposium. “Earth’s First Crust” is a hot topic that requires input from many disciplines and is widely debated since we seem to have lost it some time in the Hadean.
We plan for a lively discussion based on short talks. The speaker schedule is not set, so its safest to attend the whole event. The current list of scheduled presenters is:
Solidification of the magma ocean
– John Hernlund, Keiko Hamano, Hidenori Genda
What can the moon’s crust tell us about the Earth’s first crust?
– Shige Maruyama
What can the Mars crust tell us about the Earth’s first crust?
– Tomo Tsui
The composition of chondrites from Sm/Nd isotopes
– Ryota Fukai
Clues of first crust from the oldest Archean rocks
– Yuichiro Ueno
1:00pm – 6pm Future of Prebiotic Chemistry (ELSI 2 406/407)
The aftershop is intended to generate new collaborative research ideas within the field of prebiotic chemistry. The schedule of the aftershop is as follows:
- 1:00 – 1:10pm Opening remarks
- 1:10 – 1:30pm Introductions
- 1:30 – 2pm 4 x 5-10 min short presentations by selected presenters with questions
- 2:00 – 2:30pm Speed dating round table
- 2:30 – 3:00pm Idea-post-it brain storming session
- 3:00 – 3:20pm coffee break
- 3:20 – 3:40pm Divide up into four break-out groups
- 3:40 – 4:40pm Breakout group discussion
- 4:45 – 5:45pm Breakout group presentations and discussion

9:00am – 12:30pm Chemistry to Computation: Why Is it So Hard and Can Thermodynamics Help? (ELSI Hall)
The discussions will concentrate on the following topics:
- What general ingredients do we need for the emergence of complex organisations?
- Certiain network topologies seem favorable (e.g. scale free)
- Certain thermodynamic regimes (criticality)
- Large combinatoric spaces (but not too large)
- What has thermodynamics already given us
- The Second Law (life a manifestaton of it)
- Maximum Entropy Production Principle, but it doesn’t work. However Jaynes approach to statistical mechanics seems helpful. What do we think about high density of trajectories translating to most stable attractors?
- Onsager’s relations (sometimes seem to remain correct well beyond the linear regime)
- Stochastic thermodynamics (good for small systems, how far can we use it with larger systems?)
- Under what conditions are complexity, computation, learning the most stable attractors?
1:30pm – 5:00pm Ancestral States and Their Properties (ELSI 2 406/407)
In this aftershop, we peer into the ways that we gain insight into ancient historical biology and its relationships to the Earth. Over half a day, we will:
- Discuss in groups how ancestral biological states are inferred.
- Try to identify how the limits of these inferences can be identified by hypothesis testing.
- Attempt to evaluate the significance of inferred results in light.
