Signal
* All signals are means of visually communicating a message.
* Every signal has a frequency spectrum.
* Some signals actually bounce of the earth's atmosphere and can travel thousands of miles
  - change their frequency content over time
* also come down from the cerebral cortex to the inner ear, forming multiple feedback loops
  - have a property called wavelength , which is inversely proportional to the frequency
* are a form of expressive communication
  - limited but useful form of interprocess communication
  - primitive form of interprocess communication
  - an important part of railroading
  - carried across a synaptic cleft by a. neurotransmitters
  - electrochemical
  - incitement
  - simply the electric or electromagnetic encoding of data
  - software generated interrupts that are sent to a process when a event happens
  - transduced within cells or in between cells and thus form complex signaling networks
* can travel no faster than the velocity of light.
* is communication
* move up and down the spinal cord in bundles of sheathed axons.
* overlapping does happen from time to time.
* pass through the human body without attenuation.
* plays a key role in night vision performance.
* refers to the noise generated.
* sent between cells are necessary for large multicellular organisms to exist.
* serve as species-typical signatures in many species.
* travel along the axon by generating and propagating an action potential.
* travel through cables at a percentage of the speed of light
  - the auditory nerve to the brain for processing

### entity:

Smile
* are facial expression
  - the external expression of an inner titter
* attract others and therefore contribute to magnetism.
  * A 'smile' face made by flexing the muscles near both ends of the mouth. The neuropsychophysiological construction of the human smile. Smiles usually show happiness.

### entity:

Somebody
* making a noise while eating food, that is the sound of chewing food.
+ Denmark, Transport: European Union member states :: Nordic countries :: Current monarchies
  * There are still many islands with no bridges to the mainland. People have to go by boat or airplane to reach these islands. Many islands will never be reached by bridges, because they are too small or too far away. If the island has too few people, bridges are often not built because it is expensive to build. Somebody has to pay for it, nothing is free.
  * All these articles listed for En. Somebody just needs to grab some of it and bring it here. I have given up on simplifying articles, so I don't think it will be me.
  * Somebody needs to review the and stop looking at the lead.
