Should government intelligence agencies be trusted?
|
view preview
Whenever I think of the topic of government spying, I get flashbacks from a scene of a movie called "Good Will Hunting". In this one scene, the protagonist, who, in typical Hollywood fashion happens to be a polymath in practically all math and science-related subjects, is interviewed by the NSA after learning of his problem-solving brilliance. During the interview, the agent asks the protagonist why he has doubts about working for them, only to learn what the protagonists actually thinks of their organization. In a nutshell, he believes that by working for the NSA, his codebreaking skills would only be used to inflict harm on others, and lead to a chain reaction of unexpected catastrophic events. Watch: Unfortunately, many people hold the be ...

Like a snowflake, you're one of a kind
|
view preview
That's a pickup line sure to get one's attention if he/she knew that all snowflakes are, in fact, one of a kind! All snowflakes start off looking basically the same, but they are individually shaped by their environments as they form and fall. First, water vapor condenses and freezes on a dust mote. The snowflake starts as a six-sided prism - six sides because of the way water molecules arrange themselves into ice crystals. As it grows, its edges expand and create branches of ice that shoot out from its corners. Differences in temperature and wind conditions turn the branches into one-of-a-kind works of art: Some are long and thin, some are short and fat, and some are covered in dozens of tiny sub-branches.

Should you eat snow?
|
view preview
You've probably heard the saying 'don't eat yellow snow', for obvious reasons. Unfortunately, according to a new study published in the journal Environmental Science: Processes & Impacts, you shouldn’t eat any snow. Snow has been found to act as a rather effective sink for tiny particles that are found primarily in car exhaust fumes, so any consumption of it is effectively like eating a pollution-flavored Popsicle. Researchers of this study found that from just one hour of exposure, the levels of pollutants within the snow increased dramatically, with toxic particles becoming trapped within the small ice particles or dissolved within pockets of meltwater. This means that snow is a particularly effective “sink” for car exhaust pollution. Sour ...

Super large snow flakes spotted all over New York City
|
view preview
These snowflakes were spotted all over New York City. Meteorologist Chris Dolce explained that all of these sightings are due to the specific way they've fallen: If snowflakes stay separated from each other like you see in these photos, and if you look closely enough, you can sometimes see the structure of snowflakes with your naked eye.
There are many different types of crystal patterns and these star-shaped snowflakes are just one example. The dendrite, a star-shape with varying patterns, is the most common shape of a snowflake. ...

A carefree seal

view preview
Meet the ribbon seal, native to the icy waters off the southern coast of Russia. With no confirmed predators (except humans who occasionally hunt them), these seals are known for being super relaxed, and will let you walk right up to them on the ice floes.
