The 3 core sciences namely Biology, Chemistry, and Physics will be updated for first teaching in August 2023, with first examinations in May 2025. The syllabus change was originally scheduled for 2021, though the COVID-19 pandemic caused the IB to delay the syllabus change to 2023. Details of the specific changes can be found on the IBO website.
The International Physics Olympiad (IPhO) is an annual physics competition for high school students. It is one of the International Science Olympiads. The first IPhO was held in Warsaw, Poland in 1967. [1] Each national delegation is made up of at most five student competitors plus two leaders, selected on a national level.
To officially participate in an official IB Middle Years Programme, students must attend an authorised IB World School. [4] In the U.S., the MYP is often taught throughout middle school and the first two years of high school. Typically, middle schools and high schools work in coordination with each other. [5]
In the past, Theory of Knowledge was assessed in two parts: an externally examined 1200- to 1600-word essay and an internally assessed presentation. As of 2022, this has been replaced with an exhibition. [4]: 41 Each part is scored using assessment criteria, which differ between the essay and presentation. The total score is converted into a ...
To participate in the IB Primary Years Programme, students must attend an authorised IB World School. [4] "A PYP school is expected to implement the programme in an inclusive manner, so that all students in all the grades/year levels in the school or in the primary division of a school are engaged fully with the PYP."
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
In physics, the n-body problem is the problem of predicting the individual motions of a group of celestial objects interacting with each other gravitationally. [1] Solving this problem has been motivated by the desire to understand the motions of the Sun, Moon, planets, and visible stars.
Some trajectories of a particle in a box according to Newton's laws of classical mechanics (A), and according to the Schrödinger equation of quantum mechanics (B–F). In (B–F), the horizontal axis is position, and the vertical axis is the real part (blue) and imaginary part (red) of the wave function.
