The School Mathematics Project started in the 1960s, and brought modern ideas — modern for schools, that is — into the curriculum, introducing pupils to mathematical structure as evident in (I believe) sets, graphs, geometric symmetry groups, and logic circuits. But to make room for these, other topics had to go. What follows is my conversion into HTML: the original, which I came across last night, was printed with the same fonts and layout as an A-level, the exam taken before leaving school at 17.

As a result of recent reconstruction, the School Mathematics Project has a large amount of material for disposal at reduced prices, and offers to interested readers the following

- 1 uniform ladder, complete with rough ground and smooth wall
- 1 hemispherical bowl of radius
*a*, supplied together with - 1 uniform rod, of length
*2a . sin θ*, with perfectly rough ends - 2 particles, connected by a light inextensible string
- 2 rigid, smooth, incompressible, and perfectly
elastic spheres of masses
*m*and*em*(masses*M*and*eM*can be supplied, if preferred). - 1 hank uniformly flexible string
- 1 set assorted frictionless massless pulleys, in uniform box, guaranteed not to influence acceleration.

- 1 rigid body, complete with axis, of moment of inertia
*I*(Moments of inertia*A*,*B*, and*C*can be supplied at slight extra charge) - 1 isoceles wedge with different coefficients of friction on all three faces, complete with pulley at apex (a connoisseur's item)
- 1 bottle of resisting medium, capable of extending
to approximately
*550gt/2240k*feet. *n + 1*bricks, ready stacked in a pile with a uniform overlap.

The whole ready packed in a perfectly rough
hollow sphere of radius *r* and negligible thickness.
Price *a + bx*, where *a* and *b* are constants and
*x* is the
distance from the orchard at Woolsthorpe, Lincs.
