Sir Isaac Netwotn’s three laws of motion. Three states of matter (solid, liquid, gas). We live on the third rock from the sun. Our metric system of measurement uses metre, litre, and gram. Morse code is a reliable system as the signal is made up of only three parts – a long ‘on’, the dash; a short ‘on’, the dot; and an ‘off’ signal. Do you know what SOS means in Morse code?
How long is a day? It's the amount of time it takes for the Earth to rotate one time on its axis. But how long does it take the Earth to rotate? That is where things become completely arbitrary. The world has decided to standardize on the following increments:
Boolean logic consists of three logical operators:
OR, AND, NOT
OR logic collates the results to retrieve all the unique records containing one term, the other, or both. The more terms or concepts we combine in a search with OR logic, the more records we will retrieve
The more terms or concepts we combine in a search with AND logic, the fewer records we will retrieve.
A few Internet search engines make use of the proximity operator NEAR. A proximity operator determines the closeness of terms within the text of a source document. NEAR is a restrictive AND. The closeness of the search terms is determined by the particular search engine. Google defaults to proximity searching by default.
NOT logic excludes records from your search results. Be careful when you use NOT: the term you do want may be present in an important way in documents that also contain the word you wish to avoid.
Baird was an early pioneer in this area, and one of the first techniques developed employed a system whereby the normal frame frequency was increased by a factor of three, each successive frame containing the material for one primary color. Continue reading Color television
Red, green, and blue are the colors that the first astronauts to Mars might plant there. The three colors were chosen recently by the Mars Society for its first Martian flag. The Mars Society is a group of scientists and laypeople whose goal is promoting the exploration and settlement of the Red Planet. Continue reading THREE CHEERS FOR THE RED, GREEN, & BLUE!
In the science of numerology, a person with the birth number of Three show a keen, intuitive mind, with the ability to learn things rapidly, often at an early age. Talent, versatility and gaiety are their traits.
