An article demonstrating mathematically how various physical modelling assumptions affect the solution to the seemingly simple problem of the projectile.
The third installment in our series on the shape of astronomical systems, this article explores galaxies and the universe beyond our solar system.
How do these modelling assumption affect the solutions?
This is about a fiendishly difficult jigsaw and how to solve it using a computer program.
See how differential equations might be used to make a realistic model of a system containing predators and their prey.
At what positions and speeds can the bomb be dropped to destroy the dam?
An advanced mathematical exploration supporting our series of articles on population dynamics for advanced students.
This is our collection of tasks on the mathematical theme of 'Population Dynamics' for advanced students and those interested in mathematical modelling.
This article explores ths history of theories about the shape of our planet. It is the first in a series of articles looking at the significance of geometric shapes in the history of astronomy.
Use the computer to model an epidemic. Try out public health policies to control the spread of the epidemic, to minimise the number of sick days and deaths.
Third in our series of problems on population dynamics for advanced students.
How do you write a computer program that creates the illusion of stretching elastic bands between pegs of a Geoboard? The answer contains some surprising mathematics.
Fourth in our series of problems on population dynamics for advanced students.
Fifth in our series of problems on population dynamics for advanced students.
Second in our series of problems on population dynamics for advanced students.
Sixth in our series of problems on population dynamics for advanced students.
Look at the calculus behind the simple act of a car going over a step.
See how the motion of the simple pendulum is not-so-simple after all.
chemNRICH is the area of the stemNRICH site devoted to the mathematics underlying the study of chemistry, designed to help develop the mathematics required to get the most from your study. . . .
Explain why, when moving heavy objects on rollers, the object moves twice as fast as the rollers. Try a similar experiment yourself.
PhysNRICH is the area of the StemNRICH site devoted to the mathematics underlying the study of physics
This problem opens a major sequence of activities on the mathematics of population dynamics for advanced students.
First in our series of problems on population dynamics for advanced students.

Can you suggest a curve to fit some experimental data? Can you work out where the data might have come from?
Invent scenarios which would give rise to these probability density functions.
This article explains the concepts involved in scientific mathematical computing. It will be very useful and interesting to anyone interested in computer programming or mathematics.
Fancy a game of cricket? Here is a mathematical version you can play indoors without breaking any windows.
Why MUST these statistical statements probably be at least a little bit wrong?
This is the section of stemNRICH devoted to the advanced applied mathematics underlying the study of the sciences at higher levels
In this article for teachers, Alan Parr looks at ways that mathematics teaching and learning can start from the useful and interesting things can we do with the subject, including. . . .
In four years 2001 to 2004 Arsenal have been drawn against Chelsea in the FA cup and have beaten Chelsea every time. What was the probability of this? Lots of fractions in the calculations!
A player has probability 0.4 of winning a single game. What is his probability of winning a 'best of 15 games' tournament?
You have two bags, four red balls and four white balls. You must put all the balls in the bags although you are allowed to have one bag empty. How should you distribute the balls between the two. . . .
At Holborn underground station there is a very long escalator. Two people are in a hurry and so climb the escalator as it is moving upwards, thus adding their speed to that of the moving steps. . . .
Formulate and investigate a simple mathematical model for the design of a table mat.
What shapes should Elly cut out to make a witch's hat? How can she make a taller hat?
Your school has been left a million pounds in the will of an ex- pupil. What model of investment and spending would you use in order to ensure the best return on the money?
This article for students introduces the idea of naming knots using numbers. You'll need some paper and something to write with handy!
A brief video explaining the idea of a mathematical knot.
The builders have dug a hole in the ground to be filled with concrete for the foundations of our garage. How many cubic metres of ready-mix concrete should the builders order to fill this hole to. . . .
