Time

**Big Bang Theory**
1. The big bang theory happened about 13.7 billion years ago. 2. Black holes are the ares of intense gravitational pressure. 3. It continues to expand and cool to this day and we are inside of it. 4. Experts however say that there was no explosion. 5. Another misconception is that we tend to image the singularity as a little fireball appearing somewhere in space.

Time keeps on slippin'

1. The Gregorian Calender. It is the internatiol accepted civil calendar. 2. A leap year (or intercalary year) is a year containing one extra day (or, in the case of lunisolar calendars, a month) 3. Lunar, solar and lunisolar. 4. Before Christ. 5. Before Common Era 6. Anno Domini or year of our Lord referring to the year of christ's birth. 7. Common Era. 8. Million Years Ago 9. 21 10. Eon is the longest division of geological time. Epoch is a period marked by distinctive character or reckoned from a fixed point or event. Era is is usually divided into two or more periods. Age is how long something has existed. 11. The sun, moon, and planets. 12. Sun Clock is a device that measures time by the position of the Sun. Water clock- the water travelled from the higher container to the lower container through a connecting tube. The containers had markings on them to show the level of the water and these marks told the time. 13. During these times, simple sundials placed above the doorways were used to identify midday and four "tides" (important times of periods) of the sunlit day. 14. The standard clocks have reconances each chemical element and compound absorbs and emits electromagnetic radiation at its own characteristic frequencies. 15. A time zone is a region of the earth that has uniform standard time, usually referred to as local time. 16. Prime meridian at zero degree longitude form which east and west are reckoned (usually the greenwich longitude in England) 17. Toronto 11am. London 4pm. Moscow 7pm. Tokyo 1am. Hawaii 6am. 18. Daylight saving time time during which clocks are set one hour ahead of local standard time widely adopted during summer to provide extra daylight in the evenings. No we dont use daylight saving time in Saskatchewan. 19. Year Zero does not exist in the widely used gregorian calendar. 20. 2010 is the start of new decade 21. Linear Time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the size of the input to the problem. 22. Recurring or revolving cycles.
