GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
The UK Government introduced a new performance indicator called the English Baccalaureate, which measures the percentage of students in a school who achieve 5+ A*-C grades (now five Grades 4 to 9 since the GCSE Reforms) in English, mathematics, two sciences, a foreign language and history or geography at GCSE level.

[note 1] The mathematical description of motion, or kinematics , is based on the idea of specifying positions using numerical coordinates. Movement is represented by these numbers changing over time: a body's trajectory is represented by a function that assigns to each value of a time variable the values of all the position coordinates.
In June, Paper 3 of the Mathematics GCSE (Higher Tier, 1MA1/03) appeared to contain an exam question which was published in an AQA (another British exam board) Further Mathematics textbook. The exam question had the same diagram, values and answer as the question in the textbook. Pearson Edexcel said that they were investigating how this might ...
However, while its value is not known to great precision, the possibility of observing type Ia supernovae which happened in the universe's remote past, paired with the assumption that the physics involved in these events is universal, allows for an upper bound of less than 10 −10 per year for the gravitational constant over the last nine ...
This approach is extremely important in physics, because the constraints usually are a consequence of the physical processes that cause the wave to evolve. For example, if F ( x , t ) {\displaystyle F(x,t)} is the temperature inside a block of some homogeneous and isotropic solid material, its evolution is constrained by the partial ...
The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.
The change in unit was the result of the demise of the calorie as a unit in physics and chemistry. Both von Mayer and Joule met with initial neglect and resistance despite having published in leading European physics journals, but by 1847, a lot of leading scientists of the day were paying attention.
