38 Ideas to Use Google Drive in Class August 11, 2014 This is the third post in a series of posts aimed at helping teachers and educators make the best out of Google Drive in classrooms. This series comes in a time when teachers are getting ready to start a new school year and hopefully will provide them with the necessary know-how to help them better integrate Google Drive in their teaching pedagogy. The two previous posts featured in this series were entitled consecutively "New Google Drive Cheat Sheet" and "Teachers Visual Guide to Google Drive Sharing". Today's post covers some interesting ideas and tips on how to go about using Google Drive in your classroom. This work is created by Sean Junkins from SeansDesk. Google Docs
DIY Crafts, Projects And Handmade Gift Ideas - Craftbits.com Topology Möbius strips, which have only one surface and one edge, are a kind of object studied in topology. Topology developed as a field of study out of geometry and set theory, through analysis of such concepts as space, dimension, and transformation. Such ideas go back to Leibniz, who in the 17th century envisioned the geometria situs (Latin for "geometry of place") and analysis situs (Greek-Latin for "picking apart of place"). Topology has many subfields: See also: topology glossary for definitions of some of the terms used in topology, and topological space for a more technical treatment of the subject. History[edit] Topology began with the investigation of certain questions in geometry. Modern topology depends strongly on the ideas of set theory, developed by Georg Cantor in the later part of the 19th century. For further developments, see point-set topology and algebraic topology. Elementary introduction[edit] Topological spaces show up naturally in almost every branch of mathematics.
Fun with Foam Printing - Easy Tutorial I loved this idea because not only can you recycle these horrid polystyrene containers, but the process is really simple. You could even use tracing paper and trace your design so you don't even need to be able to draw. You could make a whole series of cards like this or just a colorful print to hang on your wall and cheer up the place. Materials needed: Foam or polystyrene container pencil paint or ink small roller 1. 2. 3. 4. 5. Happy printing!

Starting the pendulum from a slightly different initial condition would result in a completely different trajectory. The double rod pendulum is one of the simplest dynamical systems that has chaotic solutions. Chaos: When the present determines the future, but the approximate present does not approximately determine the future. Chaotic behavior can be observed in many natural systems, such as weather and climate.[6][7] This behavior can be studied through analysis of a chaotic mathematical model, or through analytical techniques such as recurrence plots and Poincaré maps. Introduction[edit] Chaos theory concerns deterministic systems whose behavior can in principle be predicted. Chaotic dynamics[edit] The map defined by x → 4 x (1 – x) and y → x + y mod 1 displays sensitivity to initial conditions. In common usage, "chaos" means "a state of disorder".[9] However, in chaos theory, the term is defined more precisely. where , and , is: .
How to make gift bags from newspaper When I bought something at a store recently, the clerk handed me my purchase in a bag made from a newspaper. I liked it very much and had to make some more—thus today's DIY recycled newspaper project: gift bags made from the Wall Street Journal. You can vary the dimensions, of course, but here's what I used to create a bag that's 5" tall, 4.5" wide, and 3" deep. Stack two sheets of newspaper on top of each other. This will be a two-ply bag for extra sturdiness. Cut out a rectangle that's 15.5" wide and 8.25" tall. Fold a flap 1.25" down from the top. Cut two pieces of cardstock or chipboard to 4.25" x 1", then glue them on the widest two panels just under the top fold. Put glue on the outside of the 0.5" tab and bring the left-most panel over to form the body of the bag, aligning the cut edge of the panel with the folded edge of the flap. Upend the bag so the 2" flap is now up. Put glue on both flaps and fold them inward to form the bottom of the bag.
Infinite [Internet Encyclopedia of Philosophy] Working with the infinite is tricky business. Zeno’s paradoxes first alerted philosophers to this in 450 B.C.E. when he argued that a fast runner such as Achilles has an infinite number of places to reach during the pursuit of a slower runner. Since then, there has been a struggle to understand how to use the notion of infinity in a coherent manner. This article concerns the significant and controversial role that the concepts of infinity and the infinite play in the disciplines of philosophy, physical science, and mathematics. Philosophers want to know whether there is more than one coherent concept of infinity; which entities and properties are infinitely large, infinitely small, infinitely divisible, and infinitely numerous; and what arguments can justify answers one way or the other. Here are four suggested examples of these different ways to be infinite. This article also explores a variety of other questions about the infinite. Table of Contents 1. a. b. How big is infinity?

(Separately it was shown that large spherically symmetrical masses attract and are attracted as if all their mass were concentrated at their centers.) This is a general physical law derived from empirical observations by what Isaac Newton called induction.[2] It is a part of classical mechanics and was formulated in Newton's work Philosophiæ Naturalis Principia Mathematica ("the Principia"), first published on 5 July 1687. (When Newton's book was presented in 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from him – see History section below.) In modern language, the law states the following: History[edit] Early History[edit] Plagiarism dispute[edit] Hooke's work and claims[edit] Vector form[edit]
one of my zipper creations. Newton's laws of motion First law: When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.[2][3]Second law: F = ma. The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object.Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687.[4] Newton used them to explain and investigate the motion of many physical objects and systems.[5] For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.
