أولاً : فهرس الحلقات
VOD1. Introduction
This preview introduces revolutionary ideas and heroes
from Copernicus to Newton, and links the physics of the heavens and the earth.
VOD2. The Law of Falling Bodies
Galileo's imaginative experiments proved that all bodies fall
with the same constant acceleration.
VOD3. Derivatives
The function of mathematics in physical science
and the derivative as a practical tool.
VOD4. Inertia
Galileo risks his favored status to answer the questions
of the Universe with his law of inertia.
VOD5. Vectors
Physics must explain not only why and how much, but also
where and which way.
VOD6. Newton's Laws
Newton lays down the laws of force, mass,
and acceleration.
VOD7. Integration
Newton and Leibniz arrive at the conclusion that differentiation
and integration are inverse processes.
VOD8. The Apple and the Moon
The first real steps toward space travel are made as Newton discovers
that gravity describes the force between any two particles in the universe.
VOD9. Moving in Circles
A look at the Platonic theory of uniform circular motion.
VOD10. Fundamental Forces
All physical phenomena of nature are explained by four forces: two
nuclear forces, gravity, and electricity.
VOD11. Gravity, Electricity, Magnetism
Shedding light on the mathematical form of the gravitational, electric,
and magnetic forces.
VOD12. The Millikan Experiment
A dramatic recreation of Millikan's classic oil-drop experiment to
determine the charge of a single electron.
VOD13. Conservation of Energy
According to one of the major laws of physics, energy is neither created
nor destroyed.
VOD14. Potential Energy
Potential energy provides a powerful model for understanding why the
world has worked the same way since the beginning of time.
VOD15. Conservation of Momentum
What keeps the Universe ticking away until the end of time?
VOD16. Harmonic Motion
The music and mathematics of periodic motion.
VOD17. Resonance
Why a swaying bridge collapses with a high wind, and why a wine glass
shatters with a higher octave.
VOD18. Waves
With an analysis of simple harmonic motion and a stroke of genius,
Newton extended mechanics to the propagation of sound.
VOD19. Angular Momentum
An old momentum with a new twist.
VOD20. Torques and Gyroscopes
From spinning tops to the precession of the equinoxes.
VOD21. Kepler's Three Laws
The discovery of elliptical orbits helps describe the motion of heavenly
bodies with unprecedented accuracy.
VOD22. The Kepler Problem
The deduction of Kepler's laws from Newton's universal law of gravitation
is one of the crowning achievements of Western thought.
VOD23. Energy and Eccentricity
The precise orbit of a heavenly body — a planet, asteroid, or comet — is
fixed by the laws of conservation of energy and angular momentum.
VOD24. Navigating in Space
Voyages to other planets use the same laws that guide planets
around the solar system.
VOD25. Kepler to Einstein
From Kepler's laws and the theory of tides, to Einstein's general theory
of relativity, into black holes, and beyond.
VOD26. Harmony of the Spheres
A last lingering look back at mechanics to see new connections
between old discoveries.
VOD27. Beyond the Mechanical Universe
The world of electricity and magnetism, and 20th-century discoveries
of relativity and quantum mechanics.
VOD28. Static Electricity
Eighteenth-century electricians knew how to spark the interest of an
audience with the principles of static electricity.
VOD29. The Electric Field
Faraday's vision of lines of constant force in space laid the foundation
for the modern force field theory.
VOD30. Potential and Capacitance
Franklin proposes a successful theory of the Leyden jar and invents
the parallel plate capacitor.
VOD31. Voltage, Energy, and Force
When is electricity dangerous or benign, spectacular or useful?
VOD32. The Electric Battery
Volta invents the electric battery using the internal properties of different metals.
VOD33. Electric Circuits
The work of Wheatstone, Ohm, and Kirchhoff leads to the design
and analysis of how current flows.
VOD34. Magnetism
Gilbert discovered that the earth behaves like a giant magnet.
Modern scientists have learned even more.
VOD35. The Magnetic Field
The law of Biot and Sarvart, the force between electric currents,
and Ampère's law.
VOD36. Vector Fields and Hydrodynamics
Force fields have definite properties of their own suitable for scientific study.
VOD37. Electromagnetic Induction
The discovery of electromagnetic induction in 1831 creates an
important technological breakthrough in the generation of electric power.
VOD38. Alternating Current
Electromagnetic induction makes it easy to generate
alternating current while transformers make it practical to distribute it over long distances.
VOD39. Maxwell's Equations
Maxwell discovers that displacement current produces electromagnetic waves or light.
VOD40. Optics
Many properties of light are properties of waves, including reflection,
refraction, and diffraction.
VOD41. The Michelson-Morley Experiment
In 1887, an exquisitely designed measurement of the earth's
motion through the ether results in the most brilliant failure in scientific history.
VOD42. The Lorentz Transformation
If the speed of light is to be the same for all observers, then the length
of a meter stick, or the rate of a ticking clock, depends on who measures it.
VOD43. Velocity and Time
Einstein is motivated to perfect the central ideas of physics, resulting
in a new understanding of the meaning of space and time.
VOD44. Mass, Momentum, Energy
The new meaning of space and time make it necessary to formulate a
new mechanics.
VOD45. Temperature and Gas Laws
Hot discoveries about the behavior of gases make the connection
between temperature and heat.
VOD46. Engine of Nature
The Carnot engine, part one, beginning with simple steam
engines.
VOD47. Entropy
The Carnot engine, part two, with profound implications for the behavior
of matter and the flow of time through the universe.
VOD48. Low Temperatures
With the quest for low temperatures came the discovery that all elements
can exist in each of the basic states of matter.
VOD49. The Atom
A history of the atom, from the ancient Greeks to the early 20th century,
and a new challenge for the world of physics.
VOD50. Particles and Waves
Evidence that light can sometimes act like a particle leads to
quantum mechanics, the new physics.
VOD51. From Atoms to Quarks
Electron waves attracted to the nucleus of an atom help account
for the periodic table of the elements and ultimately lead to the search for quarks.
VOD52. The Quantum Mechanical Universe
A last look at where we've been and a peek into the future.
