Most widely held works by Timothy David
Trouble over here, trouble over there by Trouble Funk (Musical group)( Recording )

5 editions published in 1987 in Undetermined and held by 7 WorldCat member libraries worldwide

Moving bodies with variable mass : impulse( Visual )

1 edition published in 2000 in English and held by 7 WorldCat member libraries worldwide

Using Newton's second law and a balloon-powered toy car, this program examines how impulse relates to the change in momentum and how the rate of that change equates to the resultant force. In addition, the exhaust velocity of the jet-propelled car is estimated
Simple harmonic motion 3 : resonance( Visual )

1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide

In this program, resonance is examined. The value of mathematical models is demonstrated through the physics of applying a time-varying force to a body that fundamentally exhibits simple harmonic motion. Solution techniques for general linear second-order differential equations are featured
Modelling forces : sliding and toppling( Visual )

1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide

This program discusses how geometry, gravity, and the coefficient of friction determine whether an object slides or topples. The mathematical models behind these phenomena are presented through examples such as ice hockey and skiing. The relationship between sliding and a body's velocity as an exercise in energy conservation is explored as well
Modelling with vectors : angular momentum( Visual )

1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide

In this program, animated graphics help to define the concept of angular momentum and to express the relationship between moments and the rate of change of angular momentum. Problems include determining the dimensions needed for an airplane's ailerons and the amount of force required to rotate a toy spaceship. The reasons why a spinning top shows precession are also addressed
Bikes and cars( Visual )

1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide

This program considers the idea that circular motion must imply a force or component of a force toward the center of a circle, as in the Newtonian theory of how the Moon orbits the Earth. The reasons why bicyclists lean during turns, why roads are banked, and why car tires react as they do during a turn are investigated
Moments : doors, heart valves, and flic-flacs( Visual )

1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide

After explaining the principle of moments, this program shows how apparently dissimilar physical phenomena are actually mathematically similar through the examples of a synthetic heart valve, a lock gate, and the gymnastic maneuver known as a flic-flac, or back handspring. The need to make careful approximations during the modeling process is stressed
Simple harmonic motion 1 : pendulums( Visual )

1 edition published in 2000 in English and held by 5 WorldCat member libraries worldwide

This program introduces the concept of simple harmonic motion through the operation of the pendulum. The findings of Galileo and his contemporaries on the mechanics of the pendulum are presented, along with examples of pendular motion drawn from the modern world
Take-off : moving bodies with constant mass( Visual )

1 edition published in 2000 in English and held by 5 WorldCat member libraries worldwide

This program shows that a single mathematical model can describe the take-off of a wide variety of aircraft, running the gamut from a single-engine trainer to the Concorde. Because the search for approximations is somewhat complex, graphical notation is employed to reveal the interaction and variation of the forces involved. (26 minutes)
Simple harmonic motion 2 : damping( Visual )

1 edition published in 2000 in English and held by 5 WorldCat member libraries worldwide

This program investigates how the mathematical model of simple harmonic motion becomes more complex through the introduction of damping. The application of simple modeling techniques to create homogeneous linear second-order differential equations is illustrated
Kites : modeling with vectors by Judit Kovacs( Visual )

2 editions published between 2000 and 2004 in English and held by 5 WorldCat member libraries worldwide

After defining the basic concepts of vectors, this program uses algebra to determine how the resultant of numerous forces acting on a body can be obtained and then equated to the product of mass and acceleration. Kites are employed to exemplify both equilibrium and non-equilibrium conditions
Moving bodies with variable mass : rockets and avalanches( Visual )

2 editions published between 2000 and 2004 in English and held by 5 WorldCat member libraries worldwide

In this program, footage of rockets blasting off and avalanches roaring down mountainsides provides two perspectives of the same principle: the rate of change of momentum. Practical calculations of the time it takes for a rocket to lift off and the time a skier has to escape a landslide, plus an experiment with eggs and flour, reinforce the lesson
Modeling vectors( Visual )

1 edition published in 2000 in English and held by 5 WorldCat member libraries worldwide

Employing diverse examples such as trains and water slides, this program illustrates the use of vectors to represent forces operating in both two and three dimensions. The algebraic manipulation of vectors in modeling problems is featured
Vectors and moments( Visual )

1 edition published in 2000 in English and held by 5 WorldCat member libraries worldwide

Moving beyond the concept of simple force, this program expands the application of vectors to include velocity, acceleration, and rotational motion. In addition, moments of greater complexity are investigated through vector geometry. Real-world examples are included
Drop the bomb by Trouble Funk (Musical group)( Recording )

in Undetermined and held by 4 WorldCat member libraries worldwide

Moving bodies with constant mass : bows and arrows( Visual )

1 edition published in 2000 in English and held by 4 WorldCat member libraries worldwide

In this program, geometry is combined with approximation to solve relatively complex problems involving shooting an arrow and landing an airplane on the deck of an aircraft carrier. Emphasizing the value of sketching as a visualization tool, the program also explains how the solution of the archery problem, through geometric inversion, can help solve the problem of a plane landing
Kingdom Blow by Kurtis Blow( Recording )

in Undetermined and held by 3 WorldCat member libraries worldwide

Droppin' bombs by Trouble Funk (Musical group)( Recording )

in Undetermined and held by 2 WorldCat member libraries worldwide

Moving bodies with variable mass( Visual )

1 edition published in 1999 in English and held by 1 WorldCat member library worldwide

In this program, footage of rockets blasting off and avalanches roaring down mountainsides provides two perspectives of the same principle: the rate of change of momentum. Practical calculations of the time it takes for a rocket to lift off and the time a skier has to escape a landslide, plus an experiment with eggs and flour, reinforce the lesson
Recent advances in paediatrics by Timothy David( )

1 edition published in 2003 in English and held by 0 WorldCat member libraries worldwide

This title is published annually with entirely new contents. It provides a comprehensive update of key topics in paediatrics and child health for those preparing for postgraduate exams (such as MRCPCH) as well as practising paediatricians seeking an update in their own and related specialties. Topics range across all areas of paediatrics and child health including general paediatrics, neonatal, tropical and community paediatric to satisfy the book's equally broad readership. Featuring an annotated literature review, this is a truly invaluable book for both qualified and trainee paediatricians
