Descartes & Mme La Marquise du Chatelet And The Elastic Collision of Two Bodies
http://www.maplesoft.com/applications/view.aspx?SID=153515&ref=Feed
<p><strong><em> ABSTRACT<br /> <br /> The Marquise</em></strong> <strong><em>du Chatelet in her book " Les Institutions Physiques" published in 1740, stated on page 36, that Descartes, when formulating his laws of motion in an elastic collision of two bodies B & C (B being more massive than C) <span >having the same speed v</span>, said that t<span >he smaller one C will reverse its course </span>while <span >the more massive body B will continue its course in the same direction as before</span> and <span >both will have again the same speed v.<br /> <br /> </span>Mme du Chatelet, basing her judgment on theoretical considerations using <span >the principle of continuity</span> , declared that Descartes was <span >wrong</span> in his statement. For Mme du Chatelet the larger mass B should reverse its course and move in the opposite direction. She mentioned nothing about both bodies B & C as <span >having the same velocity after collision as Descartes did</span>.<br /> <br /> At the time of Descartes, some 300 years ago, the concept of kinetic energy & momentum as we know today was not yet well defined, let alone considered in any physical problem.<br /> <br /> Actually both Descartes & Mme du Chatelet may have been right in some special cases but not in general as the discussion that follows will show.</em></strong></p><img src="/view.aspx?si=153515/Elastic_Collision_image1.jpg" alt="Descartes & Mme La Marquise du Chatelet And The Elastic Collision of Two Bodies" align="left"/><p><strong><em> ABSTRACT<br /> <br /> The Marquise</em></strong> <strong><em>du Chatelet in her book " Les Institutions Physiques" published in 1740, stated on page 36, that Descartes, when formulating his laws of motion in an elastic collision of two bodies B & C (B being more massive than C) <span >having the same speed v</span>, said that t<span >he smaller one C will reverse its course </span>while <span >the more massive body B will continue its course in the same direction as before</span> and <span >both will have again the same speed v.<br /> <br /> </span>Mme du Chatelet, basing her judgment on theoretical considerations using <span >the principle of continuity</span> , declared that Descartes was <span >wrong</span> in his statement.

<p>A recipe for cream cheese frosting I was making called for 8 oz. (about 240 grams) of cream cheese. Unfortunately, I didn't have a kitchen scale, and the product I bought came in a 400 gram tub in the shape of a<strong> truncated cone</strong>, which has a rather cumbersome volume formula. <br />Given the geometry of this tub, how deep into the tub should I scoop to get 240 grams? The mathematics is trickier than you might think but lots of fun!

<p>Any kid who's ever been entranced by an advent wreath knows that a tapered advent candle shrinks faster on Sunday night when it's new and slender than on Saturday night when it's old, stubby and caked with melted wax. How much faster? As an apropos application of math during this Christmas season, <strong>we derive a formula for the height of a burning tapered candle as a function of time</strong>. Assuming the candle has the shape of a cone when it is new and that it loses volume at a constant rate as it burns, we show that the height of the candle shrinks roughly in proportion to the cube root of time.</p><img src="/view.aspx?si=100332/thumb.jpg" alt="How Fast Does An Advent Candle Burn?" align="left"/><p>Any kid who's ever been entranced by an advent wreath knows that a tapered advent candle shrinks faster on Sunday night when it's new and slender than on Saturday night when it's old, stubby and caked with melted wax.

http://www.maplesoft.com/applications/view.aspx?SID=6589&ref=Feed
Quality control in terms of paint production consists of sampling at regular intervals to ensure that the end
product meets a set of target criteria, which include desired yield and concentration levels. These criteria are
determined by developing a model to accurately represent the reaction kinetics of the system. With a highly
accurate model of the chemical process one can quickly identify and correct sources of error during the
production process.<img src="/view.aspx?si=6589/thumb.gif" alt="Quality Control of a Paint Production Process" align="left"/>Quality control in terms of paint production consists of sampling at regular intervals to ensure that the end

Derives the optimal cruising speed of an 18-wheeler given the price of diesel, the weight of the truck, the distance of the delivery route, and the monetary value of the cargo. Makes use of a study by Goodyear on the fuel economy of 18-wheelers vs. speed and weight. Uses many features new to Maple 12, including code regions, filled 3-D plots, and rotary gauges. At the end, you can turn dials to set the parameters and watch a "speedometer" (a rotary gauge) display the optimal speed under those settings.<img src="/view.aspx?si=6573/thumb.jpg" alt="Optimal Speed of an 18-Wheeler" align="left"/>Derives the optimal cruising speed of an 18-wheeler given the price of diesel, the weight of the truck, the distance of the delivery route, and the monetary value of the cargo. Makes use of a study by Goodyear on the fuel economy of 18-wheelers vs. speed and weight. Uses many features new to Maple 12, including code regions, filled 3-D plots, and rotary gauges. At the end, you can turn dials to set the parameters and watch a "speedometer" (a rotary gauge) display the optimal speed under those settings.6573Tue, 26 Aug 2008 00:00:00 ZJason SchattmanJason SchattmanClassroom Tips and Techniques: Interactive Plotting of Points on a Curve

<p>In this third of a three-part article, we use Maple to separate variables in a partial differential equation, then show how to obtain a solution of the resulting Sturm-Liouville eigenvalue problem. The PDE is Laplace's equation in a sphere, and separation of variables leads to an eigenvalue problem involving Legendre's equation. We solve this singular Sturm-Liouville eigenvalue problem for the case of the homogeneous Dirichlet boundary condition, and for the two cases of azimuthal symmetry and asymmetry.</p><img src="/view.aspx?si=5121/R25-EigenvalueProblemsforODEs-Part3_179.jpg" alt="Classroom Tips and Techniques: Eigenvalue Problems for ODEs - Part 3" align="left"/><p>In this third of a three-part article, we use Maple to separate variables in a partial differential equation, then show how to obtain a solution of the resulting Sturm-Liouville eigenvalue problem.
