Research: Synchronization of oscillators on a network
Birds can fly because they flap their wings in-phase at the same time. We can walk because our legs move out-of-phase at the same time.… -
Visualizing Polarization
Classically, light is an electromagnetic wave– a wave of oscillating Electric and Magnetic fields instead of oscillating molecules of air or water like in sound… -
An informal introduction to spin and kets
Subatomic particles have an intrinsic property that is quite strange to us. Called spin, this property has the dimensions of angular momentum. It is a… -
Collisions
They happen all around us. Raindrops fall from the sky and collide with the ground. We have all heard of black holes colliding in spacetime.… -
Ball-drop from a tall building (a la Galileo)
We explore the physics of falling bodies by dropping various balls from the 15th floor (estimated to be about 45 to 50 metres) of a… -
Kit Experiments in Electricity and Magnetism
The Course The electromagnetic force unifying electrical and magnetic forces, is one of the four fundamental forces. With gravitation, it is one of the two… -
Kit Experiments in Mechanics
The Course Mechanics being a first course in physics training, a balance of theory and hands-on activities gets the student ready to undertake a systematic… -
Exploring a periscope made with prisms
This is a periscope made by students with two right angled prisms in a course on Optics taught by Physics faculty, Rema Krishnaswamy.(These kind of…
