The arguments themselves: whether god exists, what evil implies, what a religious claim even asserts, and whether faith can be rational.

What science is and why it works: explanation, confirmation, laws, theory change, and where the line between science and everything else falls.

The physical side of speech: how sounds are articulated, how they travel, and how a listener perceives them.

The sound system of a language: which contrasts it treats as meaningful, and the rules by which its sounds pattern.

What light does to molecules: excited states, photoreactions, and the chemistry behind photosynthesis and photovoltaics.

Light as an engineering medium: lasers, waveguides, detectors and optical fibre, and the devices that generate and steer photons the way electronics steers electrons.

Reconstructing evolutionary trees from molecular and morphological data, and the inference methods that make the reconstruction defensible.

The study of the physical principles underlying chemical systems, including thermodynamics and kinetics.

The natural half of geography: landforms, climate, soils, water and vegetation, and how they vary from place to place.

Organic reactions studied through the tools of physical chemistry: mechanisms, intermediates, rates, and the structure-reactivity relationships that connect them.

Restoring function after injury, stroke or surgery: movement, exercise and the assistive technology around them.

The study of matter, energy, and the fundamental forces that govern the natural world.

How living systems function: the mechanisms that keep an organism running, from ion channels to whole-body regulation.

Planets, moons, asteroids and comets as worlds with their own geology, atmospheres and histories. It applies the methods of the Earth sciences to bodies nobody can visit with a field hammer.

Ionized gases and their collective behaviour, from fusion devices to the solar wind.

Light coupled to electron oscillations at a metal surface, which confines it well below the wavelength that would otherwise limit it.

The devices literature works by: verse and metre, genre and figure, and the formal machinery a text uses to get its effects.

Where politics and the economy determine each other: how institutions and interests shape economic policy, and how wealth shapes political power.

States, rulers, parties and revolutions: how power was won, held and lost.

How political claims are tested: research design, causal inference and the statistical tools political scientists actually use.
