"The Science Behind the Squeaking Sound of Snow Underfoot"

Scientists have long understood how snow forms, but the reason behind the satisfying squeak it makes when walked on has been less explored. W. Craig Carter, a professor at MIT, likens the sound to breaking tiny particles, with the intricate architecture of snowflakes and sintering playing a key role. As temperatures drop, the likelihood of snow crunching increases, similar to the way wet sand also squeaks due to adhesions forming between grains.

Unveiling the Intriguing Science of Snowflakes

Physicist Brian Cox narrates a short video from the Royal Society explaining the formation of snowflakes and the groundbreaking theory about their hexagonal shape developed by Johannes Kepler in 1611. The video also reveals that snowflakes are actually clear, not white, and references the first photographs of snowflakes taken in 1885.

"The Science of Snowflakes: Unraveling the Mysteries of Winter Storms"

A winter storm brought heavy rain and snow to the East Coast, prompting curiosity about the size of snowflakes. While the Guinness World Record lists the largest snowflake at 15 inches in diameter, physicist Kenneth Libbrecht has been skeptical of this record and has conducted research to understand the true nature of snowflakes. He aims to determine whether the 1887 record is scientifically possible.

The Fascinating World of Enormous Snowflakes

The largest individual snow crystal ever observed measured 10 millimeters (0.39 inches) from tip to tip, according to Professor of Physics at Caltech Dr Kenneth Libbrecht. While reports suggest that snowflakes as large as 1 ft 3 in (38 cm) wide and 8 in (20 cm) thick have been seen, these may have been clumps of many snow crystals. Snow crystals are the result of water freezing from vapor to ice, while snowflakes can be any icy lump falling from the sky. Snow crystal enthusiasts can observe and identify different crystalline structures by following tips from Libbrecht, such as wearing something warm with a dark sleeve, using a magnifier, and familiarizing themselves with different types of snowflakes.

"Philly Region Braces for Soaker: Heavy Rain, Flooding, Wind, Snowflakes, and Cold Weather"

Heavy rain, flooding, and strong winds are hitting the Philadelphia region, with the possibility of snowflakes before it all ends. A Flood Watch is in effect for the entire region from Sunday afternoon through Monday afternoon. The heavy rain is expected to cause flooding in rivers, creeks, streams, and low-lying areas.

The Enormous Potential of Snowflakes

The largest recorded snowflakes, measuring 15 inches in width and nearly 8 inches in thickness, were spotted in Montana in 1887. However, these colossal flakes were actually clusters of ice crystals that had collided together. The typical size of a single snow crystal is much smaller, with the largest observed being about 10 millimeters in diameter. The main limit on snow crystal size is the fragility of larger crystals, which break apart easily in windy conditions. Snow crystals can take on a variety of shapes depending on temperature and humidity, ranging from simple prisms to intricate rosettes and dendrites.

Stanford Protests Spark Debate Over Free Speech and Campus Culture

Whoopi Goldberg criticized the recent law student protests at Stanford University, saying people need to understand that not everyone agrees. She called out "all the snowflakes in the world" and said that we don't show our kids how to disagree respectfully. The protests were in response to Circuit Court judge Stuart Kyle Duncan, a Trump appointee who was invited to speak on campus at a Federalist Society event. The judge was shouted down by angry students who wouldn't allow him to make his prepared remarks. The hosts of "The View" discussed the importance of the free exchange of ideas and criticized both the students and the judge for their behavior.
