Take solace from Churchill from Chapter III My Early Life: Tom Wilson, Department of Geology and Geography All my life from time to time I have had to get up disagreeable subjects at short notice, but I consider my triumph, moral and technical, was in learning Mathematics in six months. … When I look back upon those care-laden months, their prominent features rise from the abyss of memory. … We were arrived in an 'Alice-in-Wonderland' world, at the portals of which stood 'A Quadratic Equation.' …. Further dim chambers lighted by sullen, sulphurous fires were reputed to contain a dragon called the 'Differential Calculus.' But this monster was beyond the bounds appointed by the Civil Service Commissioners who regulated this stage of Pilgrim's heavy journey. In geomath we must venture forth into those dimly lit chambers to confront the dragons of Differential and Integral Calculus – but not for a while.
