Today’s entry is relatively positive one.  First of all, I had built an amplifier in Physics, increasing a voltage of 50mV (fifty milli-volts or fifty thousandths of a volt) up to a whopping 2.5V an amplification of 50 times.  Of course I cannot remember what the voltage of a circuit actually represents anymore – I wasn’t that sure at the time, although I do remember that very high voltages are not necessarily dangerous but relatively low currents (measured in Amps) can kill.  I was then about to head off on a rant about Maths – ‘had a bollocking…’ but then checked myself and described the events of the lesson as a ‘gentle reminder.’
