Word problems try and tell students a story about the math problem in front of them. They are a useful way to connect abstract numbers to concrete situations, so students can learn early on to ...

Lasers could become an important tool for detecting radioactive materials, such as those in covert nuclear weapons, from a greater distance than ever before. Writing backwards can trick an AI into ...

The diamond batteries work a bit like solar panels, but instead of converting light into energy, they capture fast-moving electrons from radioactive decay. Of course, the word “radioactive ...

Word Problems. Emily Sharp and Kunal Nabar collaborate on a puzzle that’s greater than the sum of its parts. Share full article. 366. Elephants grazing at the Kimana Sanctuary in Kenya, with ...

A highly coveted children's toy from the 1950s is going on sale—and it contains real uranium. The Gilbert U-238 Atomic Energy Laboratory, which was released in 1950, was dubbed one of 'the 10 ...

Some isotopes are stable, while others are radioactive and decay over time, emitting radiation. Carbon-14 is a radioactive isotope of carbon, meaning that it undergoes beta decay, releasing electrons.

“Word-problem solving in lower grades is one of the better indicators of overall school success in K-12,” said Lynn Fuchs, a research professor at Vanderbilt University.

Relying too much on key words can lead students astray, particularly because word problems get more complex as students go through school. Because these types of math problems require so many skills ...

“Word-problem solving in lower grades is one of the better indicators of overall school success in K-12,” said Lynn Fuchs, a research professor at Vanderbilt University. In a large national survey, ...

Researchers from KDK Collaboration at the Holifield Radioactive Ion Beam Facility of Oak Ridge National Laboratory recently made the first direct observations of the rare decay process such as K-40 ...

Now Wang and co have used the technique to watch these particles recoil as nuclei within them decay. The team start with tiny silica spheres with a diameter of about 3 micrometers, less than than the ...
