Dr. Sonwalkar is regarded as a leading expert in the application of computers in education. He has extensive research and development experience in hypermedia authoring, mobile learning, adaptive learning, and brain-based synaptic learning, advanced scientific visualization, database management systems, and computer simulation.

After receiving doctoral degree from MIT in the area of Molecular Dynamics of Nano-interfaces, he joined MIT as faculty in Mechanical Engineering, but his passion for technology enabled education led him become the founding director of Hypermedia Teaching Facility (Hypermedia Lab) at MIT and later he was appointed as the Principal Educational Architect of MIT.

lecture

In this section we will learn about magnetic force and magnetic field. We will study, also, the motion of particles in a magnetic field and the Biot-Savart law, which allows to calculate the magnetic field produced by a current.

Magnetism Segment 1: Magnetism Force and Field

Magnetism Segment 2: Applications and Ampere's Law

Magnetism Segment 3: Electromagnetic Induction

Magnetism Segment 4: Applications of Electromagnetic Induction

Magnetism Segment 5: Maxwell Equations

Magnetism Segment 6: Electromagnetic Waves

In this topic you will learn about motion of mechanical waves caused by the longitudinal and transverse motion. You will know how the sound waves are created. Relationship between wavelength, frequency and wave numbers. You will also understand the standing waves in musical instruments and Doppler's effect for measuring speed of moving sound sources and Mach number to cross the sound barrier.

Mechanical Wave Motion Segment 1: Properties of Wave Motion and Equation of Mot

Mechanical Wave Motion Segment 2: Wave Interactions

Mechanical Wave Motion Segment 3: Wave Interactions and Sound Waves

Mechanical Wave Motion Segment 4: Wave Interactions and Sound Waves
