Calculus is a branch of mathematics that deals with very small changes. Calculus consists of two main segments—differential calculus and integral calculus. Differential calculus primarily deals with the rate of change of things, while...

Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time...

Did you know that Gwen stacy's death and Newton’s second law of motion have a connection? In the comics “The Amazing Spiderman”, Gwen Stacy dies after she is pushed off a bridge. Spiderman jumps behind her to catch her in his webbing,...

Light is affected by black holes because of the theory of general relativity, which states that any massive object warps the spacetime around it. Since a photon travels by the shortest distance between two points, light appears to bend...

A unit of pressure widely used for expressing atmospheric pressure.

The story of New Zealand scientist Ernest Rutherford, who revolutionised science by discovering the structure of the atom in 1908. Chemistry - Atoms And Bonding - Learning Points. In 1908, Ernest Rutherford conducted the gold leaf...

Learn how surface area can affect the amount of pressure exerted, and why this is useful in life? Physics - Forces - Learning Points. Pressure is the amount of force acting on a set area. Pressure is measured in pascals. Pressure can be...

The world appears to be a colourful place, but what are colours? What properties of light determine what colour we see? Physics - Waves - Learning Points. Colour is how our brains perceive different wavelengths of light. Newton...

Biological evolution has allowed some animals to fly. Find out exactly how their wings work to achieve this. Physics - Forces - Learning Points. Flight occurs when the upward force is greater than the downward. Flight is explained by...

Isaac Newton's Laws of Motion explain how and why objects move as they do - the principles which underlie all of modern mechanics. Physics - Forces - Learning Points. Sir Isaac Newton published his laws of motion in 1687. Every movement...

We interleave the pages of notebooks to see how hard it is to pull them apart. As the amount of interleaving increases, we see that the force required to separate them also increases. This is because the friction between the notebooks is...

We demonstrate the effects of imbalances of pressure. A metal can is crushed by atmospheric pressure. We add some water to a can and boil it until the can is full of water vapour. It is then sealed and left to cool and after a few...

Newton's development of calculus, and how this changed the way we describe the world. Maths - History Of Maths A Twig Math Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in...

Aeroplanes use the same forces and physical principles as birds to fly. Discover how man has copied nature to achieve flight. Physics - Forces - Learning Points. Flight occurs when the upward force (lift) is greater than the downward....

Introducing the liquids whose behaviours seem to defy the accepted states of matter. What are they and why don't they behave as we predict? Chemistry - Atoms And Bonding - Learning Points. Newtonian liquids take the shape of their...
