Monday Micro Softy 36: A Glass Half Empty? Half Full? Too Big?

The professors on a research expedition must make sure that each glass of rationed water is exactly half full

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. To make sure the water lasted the entire four days, the professors made sure each portion of water filled the glass exactly halfway. There were no markings on the glass. How can they do this? We’ll give an answer next Monday right here on MindMatters.ai.    Solution Read More ›
