Essential Physics in a Nutshell. Ep 3: Complexity, Emergence and Information

Welcome!

In this thrid episode we continue our survey* of what is known and what is still not understood in the domain of Complex Systems.

We will cover:
Deterministic chaos: sensitivity of systems to initial conditions (weather, solar system, double pendulum etc).
Complex systems and the concept of emergence: when a system has properties that are not properties of its components parts. Example of emergent physics laws.
Entropy and the the second law of thermodynamics, the arrow of time, and the concept of information in physics.

The presentations, by a theoretical physicist, will be mostly qualitative and heuristic, aimed primarily at newbies and other enthusiasts. Pointers will also be provided to additional resources, most of which are freely available online (see below).

*Synopsis of the Series:

What have physicists learned about how our world works?
What do we still not understand?

Is time travel possible? What is time? Do wormholes exist?
What is dark matter? Are black holes really black?
What is quantum physics? What was there before the Big Bang?
Where are the magnetic monopoles?
Where did the elements on Earth come from?
Can the laws of Nature change with time? How will our universe end?
Is there more than one universe, with different laws?
Is there Life elsewhere in our universe?
Why are we seeking Grand Unified Theories and Theories of Everything?
Will finding those help answer the question to "Life, the Universe and Everything?" :)

That, and more, is what we intend to talk about in this series of online events aimed primarily at newbies and other enthusiasts.

But to do that, we need to first establish some common language and base knowledge. We will build that up systematically in the upcoming weeks, focussing on some core topic at each session, starting from classical physics to relativity and quantum physics and so on. We will also bring up some open problems and proposed solutions in each session.
