Here's a fun trick to show a friend, a group, or an entire class of people. Step 1) Have them take the month number from their birthday: January = 1, Feb = 2 etc. Have them give you the total. How It Works: Let M be the month number and D will be the day number. Thus, if you subtract off the 165, what will remain will be the month in hundreds plus the day!

Fibonacci Numbers, the Golden section and the Golden String Fibonacci Numbers and the Golden Section This is the Home page for Dr Ron Knott's multimedia web site on the Fibonacci numbers, the Golden section and the Golden string hosted by the Mathematics Department of the University of Surrey, UK. The Fibonacci numbers are The golden section numbers are 0·61803 39887... = phi = φ and 1·61803 39887... = Phi = Φ The golden string is 1 0 1 1 0 1 0 1 1 0 1 1 0 1 0 1 1 0 1 ... a sequence of 0s and 1s that is closely related to the Fibonacci numbers and the golden section. If you want a quick introduction then have a look at the first link on the Fibonacci numbers and where they appear in Nature. THIS PAGE is the Menu page linking to other pages at this site on the Fibonacci numbers and related topics above.

Ergodiciteit Het begrip ergodiciteit betekent dat de eigenschappen van een systeem voor elke verschijningsvorm (bijvoorbeeld over tijd, plaats, of andere variatie) hetzelfde blijven; als het systeem lang genoeg gevolgd wordt, dan komen alle mogelijke toestanden voorbij. Een ergodisch signaal is bijvoorbeeld een stationair signaal dat zowel aperiodisch maar toch terugkerend is. Dit is bijvoorbeeld het geval als een signaal een markante golfvorm heeft zonder dat deze zich over vaste intervallen herhaalt.
What Is Math: A Brief History of Mathematics First of all what is mathematics? Practically math is numbers, forms and relationships among these. Surely there’s a better definition. Names such as Pythagoras, Euclid, Thales used to send tingling feelings all over my body. They are without question synonymous with the study of math. However, for many, they are just hard-to-pronounce names discussed in class. A good example is the Lebombo bone found in Swaziland. Another artifact worthy of mention is the Ishango bone found along the borders of Uganda and Zaire close to the Nile River. With these basic mathematical tools, early humans were able to go about their daily lives. Now let’s fast forward several thousands of years to the time of the Sumerians.
The Thirty Greatest Mathematicians Click for a discussion of certain omissions. Please send me e-mail if you believe there's a major flaw in my rankings (or an error in any of the biographies). Obviously the relative ranks of, say Fibonacci and Ramanujan, will never satisfy everyone since the reasons for their "greatness" are different. I'm sure I've overlooked great mathematicians who obviously belong on this list. Following are the top mathematicians in chronological (birth-year) order. Earliest mathematicians Little is known of the earliest mathematics, but the famous Ishango Bone from Early Stone-Age Africa has tally marks suggesting arithmetic. Early Vedic mathematicians The greatest mathematics before the Golden Age of Greece was in India's early Vedic (Hindu) civilization. Top Thales of Miletus (ca 624 - 546 BC) Greek domain Thales was the Chief of the "Seven Sages" of ancient Greece, and has been called the "Father of Science," the "Founder of Abstract Geometry," and the "First Philosopher."

Seasonal Math Activities These math activities are organized by seasons. Elementary teachers often incorporate seasonal activities as craft projects. Many of these seasonal craft projects can be mathematical as well with a little forethought. Browse the activities for projects to add that reinforce mathematical concepts and skills through seasonal and holiday themes. Back-to-School Activities Back-to-School Activities: include glyphs, math-literature connection, problem solving and daily math routines.
