Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

The Universe is all of time and space and its contents.

It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, and all matter and energy.

The size of the entire Universe is unknown.

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

The brain is located in the head, usually close to the sensory organs for senses such as vision.

The brain is the most complex organ in a vertebrate's body.

In a human, the cerebral cortex contains approximately 15–33 billion neurons, each connected by synapses to several thousand other neurons.

These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

A fact is something that has occurred or is correct.

The usual test for a statement of fact is verifiability—that is, whether it can be demonstrated to correspond to experience.

Standard reference works are often used to check facts.

Scientific facts are verified by repeatable careful observation or measurement (by experiments or other means).

History (from Greek, historia, meaning "inquiry, knowledge acquired by investigation") is the study of the past as it is described in written documents.

Events occurring before written record are considered prehistory.

It is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events.

Scholars who write about history are called historians.
