BRAND NEW 2008 Line of Fractal Imagery -- 594 Images -- Oh Wow! ---> Show me the fractals! Extensive Graphical Spherical Harmonic Study --- 640+ Images ---> Take me there! 2006 Line of Fractal Imagery -- 336 Images -- Gotta See Them ---> Let's go there! Guess Your Birthday! 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! By the way, if you wish to know how many minutes and seconds you have been alive and lots more about when you were born, you might like to try this website ==> Birthday Calculator Divisibility Rules! *A big thank you to Torsten Sillke for these rules!

Phi 1.618 ø PHI: The Golden Ratio or Golden Section (In Nature, Art, Science and Religion) The Golden Section is a unique Ratio (or relationship between parts) that seems to be preferred by Nature as the best geometry for growth, energy conservation, elegance and has some fundamental relationships to the platonic solids and the Mandelbrot set. It was formally discovered by the Greeks and incorporated into their art and architecture, but it has been shown to occur even in prehistoric art, possibly as a function of Man's natural affinity for it's beauty. The rectangle at left has a vertical edge length of 1 the horizontal or width of the rectangle is 1.618 If we make a line inside and form a square (far left) it creates another 'golden rectangle' (at right) this subdivision continues inward in a spiral fashion tracing the form of a perfect PHI spiral seen in galaxies, seashells .... Even your hand, arm, ear, teeth, etc are in PHI Proportions!
Mathematically Sane Free fraction videos online Enjoy free online math videos on these fraction topics: (Fraction videos, part 2, are on this page.) The videos are recorded in high-density (HD) and are viewable both here as well as at my Youtube channel. These videos are usable for students, teachers, and parents. You can use them... To learn these topics yourself (if you're a student for example, or an adult needing a refresher)As lesson plans for teaching these topics. The videos match the lessons in my book Math Mammoth Fractions 1 (Blue Series book), or the lessons in chapter 5 of Grade 5-B (Light Blue series). Mixed numbers to fractions and vice versa I explain both the visual models and the shortcuts for converting mixed numbers to fractions or fractions to mixed numbers. To convert a mixed number to a fraction, divide the whole "pies" into pieces (the same kind of pieces as what the fractional part indicates), then figure out how many pieces you have. Adding and Subtracting Like Fractions Equivalent fractions - split the pieces!
