A mathematician explores the theoretical physical limits of human height and foot size, concluding that while extremely tall humans like Robert Wadlow are possible in theory, biological and physical constraints such as blood pressure and the square-cube law likely prevent humans from evolving to much greater heights.
The US is refilling its Strategic Petroleum Reserve (SPR) at a rate of 3 million barrels per month as oil prices decline, but there are physical limits to how much can be stored, according to a top energy official. The SPR currently holds 352 million barrels, less than half of its 2010 peak. While the Biden administration plans to continue refilling the reserve, the current rate of 3 million barrels per month represents the physical limit of capacity. The goal is to ensure a sufficient emergency stockpile for future needs.

The SPR currently holds 352 million barrels, less than half of its 2010 peak, and the Biden administration aims to continue refilling it as much as possible. However, the current rate of 3 million barrels per month represents the physical limit of the US's capacity to buy back oil.
