the six things I learned from this assignment: - humans haven't been on the earth as long as other species. - the big bang has a huge affect on our lives and species. - the "human" species has gone through tons of development. - things deemed as bad, like explosions, can end up causeing a good, helpful effect on our Earth. - although most of these events happened million of years apart, this assignment truly helped you to see that. - seaweed and algae, although they seem gross and unimportant, they had a huge affect on our Earth based on the information that they developed first.

1) What happened at 12 AM January 1, 2004? Earth formed from planetary nebula

2) What happened at 4:41 PM February, 25 2004? Inferred origin of life (first cells)

3) How long of actual time happened between the event in question one and two? 700 million years

4) What happen at 3:39 PM September 3, 2004? First multi-celled organisms (seaweed and algae)

5) What happened at 7:40 PM November 21, 2004? Ordovician system begins

6) What happened at 1:27PM December 2, 2004? First sharks

7) What happened at 12:09 PM December 12, 2004? End of Paleozoic, 96% of all Earthperishes

8) What happened at 8:37 PM December 13, 2004? First Dinosaurs

9) What happened at 7:52 PM December 26, 2004? End of Mesozoic probably meteor or comet impact

10) What happened at 5:18 PM December 31, 2004? Oldest human like ancestors

11) What happened at 11:48 PM December 31, 2004? First Modern man, Homo sapiens

12) What happened at 12:00 AM January 1, 2005? World War II

Time Keeps On Slippin’
1) What is the current calendar most of the world uses / accepts? Explain who made it and why this is accepted. The Gregorian calendar, also known as the western or Christian calendar, is the current calendar that is used by most of the world. Pope Gregory XIII created it and the world accepted because the Julian calendar suggests that the time between vertical equinoxes is 365.25 days, when it really is approximately 11 minutes less.

2) What is a leap year? Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100. centurial years that are exactly divisible by 400 are leap years. For example, the year 1900 is not a leap year and the year 2000 is a leap year.

3) List three other types of calendars used and how they set up their calendar (ex Lunar) - 360 day calendar - consists of 360 days, 12 months in a year, and 30 days in a month. -Irish Calendar – a pre-Christian Celtic system of time keeping used during Ireland’s Gaelic Era to define the beginning and length of the day, the week, the month, the seasons, quarter days, and festivals.  - Chinese Calendar - The months are lunar months. This means the first day of each month beginning at midnight is the day of the astronomical dark moon.

4) What is BC? Before Christ

5) What is BCE? Before Common Era

6) What is AD? Anno Domini. This could also mean Year of Our Lord which is in reference to Christ's Birth

7) What is CE? Common Era

8) What is MYA? Million Years Ago

9) According to the timeline site how many periods of when are there and list time. -Big Bang Theory – 14000 MYA -Formation of the earth – 4600 MYA  Cambrian: Explosion of life on the earth – 543-490 MYA  Permian: Largest mass extinction – 290-248 MYA  Mesozoic: Age of the dinosaurs – 245-65 MYA  Stone Age: Human era – 5 MYA – 2500 BC  Ice Age: Extinction of large mammals – 70000-8000 BC  Neolithic: First Permanent Settlements – 9000-4500 BC  Bronze Age: First Pharaohs – 3200-1200 BC  Iron Age: Start of the Trojan War – 1200-332 BC  Hellenistic Period – 332-63 BC  Roman Period – 63 BC – 476  Byzantine Period – 330-1453  Middle Ages – 476-1350  Renaissance – 1350-1600  Reformation – 1500-1600  Enlightenment – 1600-1800  Industrial Revolution – 1750-1900  20th Century – 1900-2000  21st Century – 2099  Future – 2009

10) What is an eon, epoch, era, and age? The largest defined unit of time is the supereon, composed of eons. Eons are divided into eras, which are in turn divided into periods, epochs and ages. The terms eonothem, erathem, system, series, and stage are used to refer to the layers of rock that correspond to these periods of geologic time

11) List three ancient calendars’ - The Egyptian Calendar -The Sumerians Calendar  -The Babylonians' Calendar

12) List two ancient clocks and how they worked. - The Sun Clock - Moving shadows formed a kind of sundial, enabling people to partition the day into morning and afternoon. - The Water Clock – stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom.

13) What was a revolution of timekeeping? Accurate Mechanical Clocks

14) What allows for standard more accurate clocks? Aztec Clock

15) What are time zones? Time zones are different times in the world.

16) What is the prime meridian? The zero meridian (0), used as a reference line from which longitude east and west is measured.

17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii? 12 PM; 5PM; 8PM; 1AM; 6AM

18) What is Daylight Saving Time? Do we use this in Saskatchewan? Every spring we move our clocks one hour ahead and “lose” and hour during the night. In Fall we move our clocks back one hour to “gain” and extra hour.

19) Is there a year zero? No

20) Are we starting a new decade in 2010 or 2011? -2010

21) What is linear time? In computer science, the 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) What is cyclical time? Of or pertaining to a cycle or circle; moving in cycles; as, cyclical time.

Bonus: In What Steve Miller song does time ‘keep slippin’ into the future’? Fly Like An Eagle

BIG BANG
1) About how long ago did the big bang take place? - The Big Bang took place about 13.7 Billion years ago.

2) What is a black hole? - a black hole is an area of intense gravitational pressure. The pressure is thought to be so intense that finate matter is actually squised into indefinite density.

3) Does the universe continue to expand? - ﻿ ﻿ Yes, the universe does continue to expand an cool down even up to this day

4) Was there really a big bang? - No, there actually wasn't a "Big Bang". Many people believe that there was a HUGE explosion when in reality our universe just continues to expand. A better way to understand the "Big Bang" is to picture a balloon, and instead of it popping and releasing all its contents, picture it expanding and continuing to grow over time.

5) What light elements seem to support the Big Bang Theory? - The "light elements" Hydrogen and Helium found in our universe are thought to support the Big Bang's origins.
