Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
The topology of an electronic circuit is the form taken by the network of interconnections of the circuit components.  Different specific values or ratings of the components are regarded as being the same topology.  Topology is not concerned with the physical layout of components in a circuit, nor with their positions on a circuit diagram.  It is only concerned with what connections exist between the components.  There may be numerous physical layouts and circuit diagrams that all amount to the same topology.
Strictly speaking, replacing a component with one of an entirely different type is still the same topology.  In some contexts, however, these can loosely be described as different topologies.  For instance, interchanging inductors and capacitors in a low-pass filter results in a high-pass filter.  These might be described as high-pass and low-pass topologies even though the network topology is identical.  A more correct term for these classes of object (that is, a network where the type of component is specified but not the absolute value) is prototype network.
Electronic network topology is related to mathematical topology, in particular, for networks which contain only two-terminal devices, circuit topology can be viewed as an application of graph theory.  In a network analysis of such a circuit from a topological point of view, the network nodes are the vertices of graph theory and the network branches are the edges of graph theory.
Standard graph theory can be extended to deal with active components and multi-terminal devices such as integrated circuits.  Graphs can also be used in the analysis of infinite networks.
