There are actually two possible solutions to last week’s puzzle, depending on how you interpret the pattern of the arithmetic.

To solve Microsofty 50, about cutting a loaf of cornbread into eight pieces by making three slices, try thinking in three dimensions.

A hint for solving Micro Softy 45: Average speed is independent of the distance to the store.

To solve Micro Softy 44, recall that Tony doesn’t need to take the individual pills each day, only the prescribed amount of each.

In Micro Softy 40, the critical question is not whether the watchman’s prophecy comes true or not; it’s how he came to learn the information anyway.

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 ›
