Fire Safety

The young man stood silent and motionless, holding a baby boy as he stared at the raging fire. The tongues of flame had consumed his garage and everything in it. Now they had jumped to his sport utility vehicle (SUV) parked close by. The single wide mobile home that he and his wife shared with their children stood about ten feet away. Thankfully, his family had escaped uninjured. The siding had been damaged by the heat of the fire, but the house had not caught…yet.

Adventures in Athens – How We Treat Others

How we treat others matters far more, to the individual and to everyone around, than we can possibly imagine. 

My daughter Anna is getting married in June, so she and I traveled to Greece this past week to adventure together one more time. It has been a marvelous week; we have enjoyed the place and enjoyed each other. I will treasure these few days forever, and I hope that she will do the same. With all of the fun that we had, God used our experiences to build our character and our faith as individuals and as the Body of Christ.

Yesterday Anna and I traveled to Corinth to see where Paul walked and worked. The ruins of the ancient city featured a temple of Apollo, a basilica of Julian, shops, houses, and the Bema where the famous apostle was tried before Gaius. After almost two hours of exploring the ruins, we agreed to finish individually and then meet at the temple to conclude our visit. I stopped by the Pirean fountain and explored the historic road entering the city. Anna finished first and went to the temple. I tried to get to the temple faster by leaving the site through the exit and reentering the main entrance.

Our Persian Sister

She moved out just over one year ago. Things had been tense for several weeks, especially since her sister had visited. We didn’t know why, but I could hear the tension in Jane’s (not her real name) voice, and see her almost continually locked door in our basement. We tried to understand why she seemed to grow more distant, but the closer we tried to get, the farther she moved away.

Jane was a young Christian Persian woman who I had met on a mission trip to Central Asia in 2011.  She had come to New York City in September 2013, lived in rooms rented from families, and ate out. She linked up with the Persian community and enjoyed the night life of the Big Apple. Perhaps to save money, Jane moved to Virginia to live with us in December 2014.

Math Days

Mathematics is one of most important fields of study in the modern world, and understanding math must be a foundational goal for every person. Unfortunately, many children, adolescents and adults fear math. It is not easy to understand and so they believe that they cannot understand it.

Families and teachers can celebrate dates that correspond to important mathematical concepts. Using food, games, and prizes, they can teach children, and themselves, that math is fun. In honor of the upcoming Square Root Day (4-4-16), I have provided this list for my readers.

Annual

Golden Ratio Day (1/6) – January 6

For over 2,000 years, scientists and artists have been fascinated with the Golden Ratio. It is defined as two quantities having the same ratio to each other that the larger of the two has to their sum. For example, a line segment AC comprised of segments AB (larger) and BC (smaller) would be in the Golden Ratio if AB+BC is to AB as AB is to BC. The decimal equivalent of the Golden Ratio is 1.618 to 1. Many proportions of the Greek Parthenon are in the Golden Ratio, as is the Great Pyramid of Giza in Egypt. The ratio is also found in music, art and nature. Do something “golden” for yourself, and for someone, else today.

E day (2/7) – February 7

E is an irrational number used in exponential and logarithmic functions. Celebrants can do things relating to e, such as eating foods (eggs, enchiladas, English muffins, etc) and doing activities (like going to the zoo to see elephants or the aquarium to see eels).

Pi Day (3/14) – March 14

Pi, the constant used to calculate the area (πr2) and circumference (2πr) of a circle, is 3.14159…. The Pi date of the century is 3/14/15. Some families serve pies of various types (pizza pie, apple pie) to observe it. Thomas Jefferson School of Science and Technology in Virginia band, cheerleaders and fans used to count down to pi in the fourth quarter of football games (3.24, 3.23…3.16, 3.15, Pi!!!) but the same countdown can be used for any sport.

Tau Day (6/28) – June 28

Some argue that Tau, not Pi, is the real circle constant (T=C/r=6.28318). If you are in this select group, express yourself by celebrating Tau day every June. The Tau date of the century is 6/28/31.

Pi Approximation Day (7/22 or 22/7 military and European notation) – July 22

Summer is a time when children often forget the lessons they learned the year before. The fractional equivalent of pi is 22/7 (3.14285…), and 22 July is almost half way between the end of one school year and the beginning of another. Families can celebrate Pi Approximation Day during the heat of summer with snow cones (V=πr3h/3), scoops of ice cream (V=4/3πr3), and of course, ice cream pies.

Gravity Day (9/8) – September 8

The acceleration due to gravity on earth is 9.8 m/s2, or 32 f/s2. Whether you are a pencil or a rock, neglecting wind resistance, you will fall to the ground at that rate. Do a gravity project, or at least gain some weight, on this happy day.

Light Speed Day (10/8) – October 8

October gets a lot of good math days because scientific notation uses 10x rather than adding a bunch of zeroes behind a number. The speed of light (3×108 m/s or 186,000 miles per second) is a fundamental constant of the universe and deserves celebration. Besides, we believe that the more celebrations, the better.

Powers of 10 Day (10/10) – October 10

The greatest power of 10 day is 10/10/10, but math nerds can celebrate powers of 10 day every year. Do ten things, spend ten dollars, or work ten puzzles. Enjoy your tens!

Mole Day (10/23) – October 23

Avagadro’s Number (6.02×1023) is a fundamental constant in chemistry, describing how many particles of any substance make a mole of that substance. Celebrate it from 0602 to 1802 (6:02 AM to 6:02 PM).

Fibonacci Day (11/23) – November 23

The sequence is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144,… Each number is produced by adding the two numbers immediately preceding. The next number in the sequence above would be 89+144 = 233. The Fibonacci sequence describes many natural phenomena including the branching of trees and generations of honeybees.

Gross Day (12/12) – December 12

A gross is 144 (12×12), whether a gross of quarters or a gross of candy canes. Families can celebrate Gross Day by making a gross of something (Christmas cookies), collecting a gross of something (beautiful fall leaves after Thanksgiving), or enjoying a gross of time (144 minutes) together (playing, singing, eating or dancing).

These days are all occasions to party, but unfortunately most of them have passed for this century. Enjoy those that remain with family and friends, and pass this list on to your grandchildren. They will have a great time.
