Every year since 2003, the Norwegian Academy of Science and Letters has bestowed the Abel Prize for excellence and contributions in the field of mathematics. Every year, the recipient has been a man. In 2019, Karen Uhlenbeck crushed that dubious tradition and became the first woman to win the Abel Prize and its $700,000 award.

An emeritus professor at the University of Texas at Austin, Uhlenbeck’s work is focused on gauge theory and geometric analysis—the latter a field she pioneered. Gauge theory supports theoretical physics and is involved in the research of particle physics and string theory. Uhlenbeck is also credited with work that led to greater comprehension of the unification of forces, a primary objective in physics that attempts to link electromagnetic force and weak nuclear force with strong nuclear force in a single theory, which would help us understand the universe.

Uhlenbeck arrived at UT Austin in 1987 and stayed after her retirement in 2014. During that time, she co-founded several programs, including the Saturday Morning Math Group and Distinguished Women in Mathematics lecture series, both in Texas, as well as the Park City Mathematics Institute and the Woman and Mathematics program at the Institute for Advanced Study in Princeton, New Jersey.

She achieved another milestone in her field in 1990, when she became the second woman (and the first since 1932) to host a plenary lecture at the International Congress of Mathematicians.

The Abel Prize, which is modeled after the Nobel Prize, is named after Norwegian mathematician Niels Hendrik Abel. Uhlenbeck will receive the prize in Oslo on May 21.

What Really Happens When Food Goes Down the 'Wrong Pipe'?

The dreaded 'wrong pipe' calamity can strike at any time.

Your average person isn’t expected to be well-versed in the linguistics of human anatomy, which is how we wind up with guns for biceps and noggins for heads. So when swallowing something is followed by throat irritation or coughing, the fleeting bit of discomfort is often described as food “going down the wrong pipe.” But what’s actually happening?

When food is consumed, HuffPost reports, more than 30 muscles activate to facilitate chewing and swallowing. When the food is ready to leave your tongue and head down to your stomach, it’s poised near the ends of two "pipes," the esophagus and the trachea. You want the food to take the esophageal route, which leads to the stomach. Your body knows this, which is why the voice box and epiglottis shift to close off the trachea, the “wrong pipe” of ingestion.

Since we don’t typically hold our breath when we eat, food can occasionally take a wrong turn into the trachea, an unpleasant scenario known as aspiration, which triggers an adrenaline response and provokes coughing and discomfort. Dislodging the food usually eases the sensation, but if it’s enough to become stuck, you have an obstructed airway and can now be officially said to be choking.

The “wrong pipe” can also be a result of eating while tired or otherwise distracted or the result of a mechanical problem owing to illness or injury.

You might also notice that this happens more often with liquids. A sip of water may provoke a coughing attack. That’s because liquids move much more quickly, giving the body less time to react.

In extreme cases, food or liquids headed in the “wrong” direction can wind up in the lungs and cause pneumonia. Fortunately, that’s uncommon, and coughing tends to get the food moving back into the esophagus.

The best way to minimize the chances of getting food stuck is to avoid talking with your mouth full—yes, your parents were right—and thoroughly chew sensible portions.

If you experience repeated bouts of aspiration, it’s possible an underlying swallowing disorder or neurological problem is to blame. An X-ray or other tests can help diagnose the issue.
