About Speaker : Arthur Eisenkraft, PhD, is one of America’s leading science educators. For 25 years, he taught high school physics and was a 6-12 science coordinator. He was past president of the National Science Teacher Association and was chair of the Science Academic Advisory Committee of the College Board. He is project director of the NSF-supported Active Physics curriculum project that is introducing physics instruction for the first time to all students and leading a similar effort with Active…
AI, Robotics, IoT part of new AICTE 2018 Undergraduate Syllabus now
In Artificial Intelligence, Centre Of Excellences, More Info, Robotics | No commentAI, Robotics, IoT part of new AICTE 2018 Undergraduate Syllabus now The much-hyped new age technologies like Artificial Intelligence and Analytics are neither new nor will they take away jobs. The Indian industry is over-glorifying machines, said Prof S Sadagopan, Director (President) of IIIT-Bangalore. Speaking about the future of jobs and the expansion of automation, Sadagopan said that automation is not the end. Every automation creates ten more jobs, Sadagopan added. “While everyone is talking about big data and analytics, the real big data is yet to come. We are at an early stage of analytics,” he said. Speaking…
Human Eye
In Atal Tinkering Labs ATL, More Info | No commentThe human eye belongs to a general group of eyes found in nature called “camera-type eyes.” Instead of film, the human eye focuses light onto a light sensitive membrane called the retina. The cornea is a transparent structure found in the very front of the eye that helps to focus incoming light. Behind the cornea is a colored ring-shaped membrane called the iris. The iris has an adjustable circular opening called the pupil, which can expand or contract depending on the amount of light entering the eye.
Spherical Mirrors
In Atal Tinkering Labs ATL, More Info | No commentThe image formed by any mirror is located either where the reflected light converges, or where the reflected light appears to diverge from. A spherical mirror is simply a piece cut out of a reflective sphere. Its center of curvature, C, is the center of the sphere it was cut from. R, the mirror’s radius of curvature is the radius of the sphere. The focal point F (the point where parallel rays are focused) is located half the distance from the mirror to the center of curvature. The focal length, f, is: focal length of a spherical mirror :…
Reflection of Sound
In Atal Tinkering Labs ATL, More Info | No commentReflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. When sound travels in a given medium, it strikes the surface of another medium and bounces back in some other direction, this phenomenon is called the reflection of sound. The waves are called the incident and reflected sound waves. First Law of Reflection: The incident wave, the reflected wave, and the normal at the point of incidence lie on…
One Dimensional Motion
In Atal Tinkering Labs ATL, More Info | No commentBy one dimension, one means motion along a line, or in one particular direction. Think of a car going down a straight road, or a person running on a straight track. Types of Motion: 1.Translational :An example is a car traveling on a highway. 2.Rotational :An example is the Earth’s spin on its axis. 3.Vibrational :An example is the back-and-forth movement of a pendulum. The object’s position is its location with respect to a chosen reference point.
Magnetism
In Atal Tinkering Labs ATL, More Info | No commentMagnetism is the force of attraction or repulsion in and around a material. Magnetism is present is all materials but at such low levels that it is not easily detected. Certain materials such as magnetite, iron, steel, nickel, cobalt and alloys of rare earth elements, exhibit magnetism at levels that are easily detectable.
Gravitational Force
In Atal Tinkering Labs ATL, More Info | No commentGravitational force is not a force of contact. Any object on the Earth or at least close to Earth, will experience a gravitational force. It is the weakest of the four fundamental forces, yet it is the dominant force in the universe for shaping the large scale structure of galaxies, stars, etc. Newton’s Law of Universal Gravitation is used to explain gravitational force .The law can be explained as : Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two…
Archimedes Principle
In Atal Tinkering Labs ATL, More Info | No commentArchimedes Principle states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object. Through the video, we can learn: 1. When a body is partly or completely immersed in water, it loses weight. 2. A body loses its maximum weight when it is completely immersed in water. 3. When a body is partly or completely in water then: Loss in weight of the body = Weight of water displaced by the body = Buoyant Force or up-thrust exerted by water on the body. Volume of…
Newton’s First Law of Motion
In Atal Tinkering Labs ATL, More Info | No commentNewton’s first law of motion states that: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is really only a definition of force. It says that when a body is acted upon by an external resultant force it will accelerate. An object resting will remain at rest, permanently, so long as nothing pushes or even pulls onto it. An object within motion will remain in motion, driving a straight line, eternally, till something forces or…
Sound- Production and Propagation
In Atal Tinkering Labs ATL, More Info | No commentSound is produced due to vibration of different objects. Sound travels as a longitudinal wave through a material medium.Sound travels as successive compressions and rarefactions in the medium. In sound propagation, it is the energy of the sound that travels and not the particles of the medium. Sound cannot travel in vacuum.
