English has many terms with multiple meanings which we use with the express intent to imbue our words with adjacent meaning. A hard decision is difficult but also unyielding. A hard man is unyielding but also strong. A strong decision is controversial but also tough. These dual meanings are often so ingrained we cannot see the inherent issues with their usage. They are often somewhat Orwellian in their duality. The hard sciences is one of those terms. Hence my joke about the easy sciences.
