What is a hard mathematics question for an Eleven Plus child? Well it would be a lot easier to answer if parts of the mathematics papers were set by physics teachers.
At school we all did `Wave Theory’. An example of wave theory is when sound vibrates on a frequency. The pitch stays the same but the volume grows quieter and quieter. A tuning fork is lightly damped because the sound persists for a long time. A bottle, when blown across the top, only emits the sound for a short time because the bottle is heavily damped so the vibrations die away quickly.
We get water waves when we throw a stone into water.
We can get ultrasonic waves when the pitch of the sound wave is too high for the human ear.
So when a parent calls a child to do an Eleven Plus paper, and the child does not appear to hear, we can only question:
Is the lack of hearing due to damping?
Was our message too quiet so that it did not cause even a ripple of consciousness?
Was the tone of voice a little too high and forced?
So now onto the mathematics question. Is this too hard for a bright Eleven Plus candidate?
England were playing a crucial football match, one fifth of the spectators left ten minutes before the end and one quarter of the remainder left in the last five minutes.
If 60 000 spectators were left in the ground when the final whistle sounded, how many spectators watched the game?
If the game was at Wembley, was England winning or losing?
Now a mathematician would work out the answer.
A physicist would tell us not to make waves!
