Humans are pretty good at guessing whether a towering stack of dishes in the sink will topple over or where a pool ball will go when a cue hits it. We evolved this kind of physical reasoning to navigate our changing and sometimes dangerous environments. But a new study highlights one area of intuitive physics that’s deceptively difficult: judging how strong a knot is. Take a look at these four knots, which may look similar but are all distinct.

Only physicists, chemists, and specialists in physiology or medicine are eligible for the honor—which comes with a gold medal, a diploma and currently up to 11 million Swedish kronor (about $1.07 million). Multimillionaire Alfred Nobel established the prize pot—and those categories—in 1895 via his last will and testament.

Meteorologist Syukuro Manabe shared the 2021 Nobel Prize in Physics for his work modeling gases’ movement through a column of atmospheric air—in the 1960s. His 60-year-old research had proved foundational for the computer models that scientists use today to interpret and predict our changing climate.

Food gives us energy, but just as important, it delivers vitamins and minerals. There is essentially no bodily function that doesn’t depend on at least one of these compounds, roughly 30 of which are considered crucial. They help our hearts beat and our lungs breathe. They enable our bodies to build new muscle, skin and bone cells. They allow nerves to send signals to the brain and the immune system to fight invaders. We literally can’t live without them.
