Here’s our thirst-quenching Micro Softy for this week. Three professors were on a trip through the Sahara Desert. They had an NSF grant to study the sleep patterns of the Saharan Grasshopper (Heteracris littoralis). They brought exactly enough drinking water with them to last for four days. To stay hydrated, each was allowed a half glass of water every hour during each sixteen-hour workday. The professors shared the water glass shown in the picture.

We’ll give an answer next Monday right here on MindMatters.ai. Solution Read More ›
