Meteorological Seasons vs. Astronomical Seasons In our investigation of the development of Leap Day, we learned the seasons would drift on our calendars if the intercalary date didn’t exist. One could argue that seasons – the result of axial tilt – are the most important planetary aspect of human existence. For millennia, in many places, people have planned […]

Taters, the Space Laser Cat “Everyone loves Taters.” –Ryan Rogalin, Jet Propulsion Laboratory In our current understanding of the cosmos, nothing travels faster than light. All the incarnations of the electromagnetic spectrum move at 299,792,458 meters per second in a vacuum, which is approximately 186,000 miles per second or 671 million miles per hour. That’s some serious

Mocha Dick Consider the subtleness of the sea; how its most dreaded creatures glide under water, unapparent for the most part, and treacherously hidden beneath the loveliest tints of azure. — Herman Melville, Moby-Dick Instead of projecting his spout obliquely forward, and puffing with a short, convulsive effort, accompanied by a snorting noise, as usual with
Orcas Attacking Boats Most fears associated with denizens of the deep are largely overblown, perhaps due to the unseen nature of the threat. Sharks, for example, despite Jaws and all the negativity associated with them, have only killed 633 people since records on the subject began in 1958. That’s under 10 per year. Documents indicate at least

A Stormcloud of Bees Throw out the word “electricity” today and one clear connotation rules. The juice that runs the world, coming to us through hanging power lines or buried cables. The electricity that runs computers, televisions, appliances, and, increasingly, automobiles. This type of power is current electricity, a stream of charged particles that travels

It’s All Mustard Today, we connotatively view mustard as a yellow condiment we might slather on sandwiches. It’s easy to forget that delicious spread comes from the seeds of plants known as mustards. In the grand genealogical tree, mustard plants fall into the Brassicaceae family. This demarcation not only includes mustards but also cabbages
DART Today, Bruce Willis, Billy Bob Thornton, Liv Tyler, Ben Affleck, Robert Duval, Tea Leoni, Elijah Wood, and Morgan Freeman are proud astronauts and scientists. Twenty-four years after the summer that gifted the world with the films Armageddon and Deep Impact, astronomers have finally started the process of catching up with late-20th-century film science. Both movies deal with
The Ozarks The area in the United States between the Appalachians and the Rockies typically garners a reputation of being flat, low, and bland. Glaciers did a wonderful job of leveling the center of the country, but anyone who’s been to the Arikaree Breaks in Kansas knows it’s not flat like an ice rink. “Low” is a
The Tube Oven In our previous exploration, we discovered London’s subway system – the Underground, lovingly called the Tube – features some strange mosquitoes. The scientific oddities of the Underground don’t stop there, however. The British constructed the earliest tunnels near the surface, but they quickly realized they could produce conduits deeper in the earth. One
Denizen’s of London’s Underground The British constructed the world’s first underground passenger railway in London in 1863. The first tunnels built for the Metropolitan Railway used the cut-and-cover method, forming conduits just below the surface. Circular holes at deeper levels soon became the preferred method. The round tunnels provided a nickname by which locals
