1 Thoughts about Time 2008 Dr. David Byers
2 Introduction Time something we all use and often wish we had more of to do more within life. Yet, how much do we really know about time?
3 TIME IS ON OUR MINDS Now s the time. Quality time Personal time What time is it? Almost time Be on time. There s no time like the present. Hold on a minute. Take your time. Time after time. One on one time Vacation time Night time Time and time again. It s about time. Seize the day. Down time Time travel Can you spare a minute? Me time Time is of the essence. Yesterday On time To everything there is a season Give me a second. You have to make time. Time of day 10, 9, 8, 7, 6, 5 If I could save time in a bottle... Don t waste time. Just a moment
4 Time Quote Lost time is never found again. Ben Franklin
5 Time Quote "It was the best of times, it was the worst of times... Charles Dickens, A Tale of Two Cities
6 Time Quote "Nine-tenths of wisdom consists in being wise in time. Theodore Roosevelt
7 Time Quote "This time, like all times, is a very good one, if we but know what to do with it." Ralph Waldo Emerson
8 Time Quote "I've been on a calendar but I have never been on time. Marilyn Monroe
9 History of the Calendar In 738 B.C., the Romans started using a 10-month calendar they borrowed from the Greeks. The original months were Marius Aprilis Maius Junius Quintilis Sextilis September October November December
10 Extra Months Are Added Later, the months Januarius and Februarius were added to account for 60 spare days. In 46 B.C., Julius Caesar changed the (Julian) calendar and gave each of the 12 months 30 or 31 days except Februarius which had 29 days. Every 4 years Februarius gained an extra day. Later he decided to make Januarius the first month, Februarius the second month, and Martius the third month. After Julius was killed, the Romans renamed the month Quintilis (now July) to Julius in his honor. Sextilis was renamed to Augustus (August) to honor Augustus Caesar who moved a day from Februarius to Augustus so he would have the same number of days as Julius. Hence February now has 28 days usually and 29 days every four years.
11 A.M. and P.M. The Romans divided the day into two halves of 12 hours each A.M. and P.M. were Roman abbreviations A.M. stands for ante meridiem (before midday) P.M. stands for post meridiem (after midday)
12 Where s Year Zero? There was no year zero. Year 1 A.D. (Anni Domini in the year of the Lord) marked the birth of Christ and the modern day calendar. Years prior to 1 A.D. are indicated by B.C. (Before Christ). In 530 A.D., a scholarly monk named Dionysius Exiguus trying to pinpoint the birth year of Christ gave us the year numbering system we still use today. Scholars now believe Dionysius miscalculated and that Christ was born somewhere between 7 B.C. and 4 B.C. because Herod the Great was known to have died in 4 B.C.
13 Leap Years A year is days long. Every 4 years we add one day (366 days) to February to account for the extra amount of time. However, there is still excess time left over. In 1582, Pope Gregory XIII (Gregorian Calendar) declared that every 400 years should be a leap year instead of every 100 years to balance out the difference. The years 1700, 1800, and 1900 were not divisible by 400 so they were not leap years.
14 Time Facts 1 picosecond (one-trillionth of a second) This is about the shortest period of time we can currently measure accurately. 1 nanosecond (one-billionth of a second) 2 to 4 nanoseconds is the length of time that a typical home computer spends executing one software instruction. 1 microsecond (one-millionth of a second) 1 millisecond (one-thousandth of a second) This is the typical fastest time for the exposure film in a normal camera A picture taken in 1/1,000th of a second will usually stop all human motion.
15 Time Facts 1 centisecond (one-hundredth of a second) The length of time it takes 1 decisecond (one-tenth of a second) A blink of an eye for lightning to strike 1 second An average person's heart beats once each second.
16 Other Time Facts 60 seconds - One minute; a long commercial 2 minutes - About as long as a person can hold his or her breath 5 minutes - About as long as anyone can stand waiting at a red light 60 minutes - An hour; about as long as a person can sit in a classroom without glazing over 8 hours - The typical workday in the United States, as well as the typical amount of sleep a person needs every night 24 hours - One day; the amount of time it takes for the planet Earth to rotate one time on its axis 7 days - One week 40 days - About the longest a person can survive without food days - One year; the amount of time it takes for the planet Earth to complete one orbit around the sun 10 years - One decade 75 years - The typical life span for a human being 5,000 years - The span of recorded history
17 Time Quote Time and tide wait for no man, but time always stands still for a woman of 30." - Robert Frost (The last portion of this quote is often omitted.)
18 Time Zones The world is divided into 24 time zones of 15 longitudinal degrees each.
19 Greenwich The Prime Meridian, located in Greenwich, England is the starting point for the time zones and is known as Greenwich Mean Time (GMT) or Universal Time. The International Date Line (IDL) is located on the opposite side of the planet from the GMT.
20 Time Quote The future is something which everyone reaches at the rate of 60 minutes an hour, whatever he does, whoever he is. - C. S. Lewis
21 Time Quote "You can fool some of the people all of the time, and all of the people some of the time, but you cannot fool all of the people all the time." Abraham Lincoln
22 Time Quote "When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to be 21 I was astonished at how much the old man had learned in seven years. Mark Twain
23 Time Quote 'Would you tell me, please, which way I ought to go from here?' 'That depends a good deal on where you want to get to,' said the Cat. 'I don't much care where --' said Alice. 'Then it doesn't matter which way you go,' said the Cat. '--so long as I get somewhere,' Alice added as an explanation. ~ Lewis Carroll, Alice's Adventures in Wonderland
24 Time Quote There is time for everything. -Thomas Edison
25 Time Quote What may be done at any time will be done at no time. - Scottish Proverb
26 Time Quote Time is the coin of your life. It is the only coin you have, and only you can determine how it will be spent. Be careful lest you let other people spend it for you. - Carl Sandburg
27 Why People Procrastinate People procrastinate because they Are waiting for the right mood Are waiting for the right time Don t understand the assignment Were given ambiguous directions Are afraid of failing Lack clear goals Found the task too difficult Can t find the time Don t want to ask for help Are afraid to admit they didn t understand Are perfectionists
28 Time Quote "The reputation of a thousand years may be determined by the conduct of one hour." Japanese proverb
29 Everybody, Somebody, Nobody and Anybody Once upon a time, there were four people; Their names were Everybody, Somebody, Nobody and Anybody. Whenever there was an important job to be done, Everybody was sure that Somebody would do it. Anybody could have done it, but Nobody did it. When Nobody did it, Everybody got angry because it was Everybody's job. Everybody thought that Somebody would do it, but Nobody realized that Nobody would do it. So consequently Everybody blamed Somebody when Nobody did what Anybody could have done in the first place.
30 The Moral The moral of the story is to COMMUNICATE effectively!
31 Now Is the Time Now is the only time there is. Make your now wow, your minutes miracles, and your days pay. Your life will have been magnificently lived and invested, and when you die you will have made a difference. -Mark Victor Hansen
