A New Era: Conquering The Crossroads of Technology

“Flying cars. Transparent gadgets. 3D-printed replacement organs. Virtual reality. Nanobots.

On the surface, it seems like we’re finally entering the futuristic world that our parents say they were promised at the World’s Fair. Upon LIGO’s discovery of Einstein’s century-old proposal of the existence of gravitational waves, many are calling this a “new era” ofscience, astronomy, andspace exploration.

Every day, we’re bombarded with a LOT of news, including news about the latest and greatest in science and technology. Whether it’s a reusable rocket or the World’s Smallest 4K Camera, cancer-killing nanobots or Solar Roadways, the hyperloop or real hoverboards, it seems like we’re on the verge of achieving utopia.

So…

Where is all of this great stuff and why aren’t we there yet?” More at thedailycosmos.com.

Leap Day…Why Does It Exist?

Once every four years, an extra calendar day is added: a leap day. But why?

The reason for adding leap days to the calendar is to align the calendar year with the actual year – which is defined by the time it takes Earth to circle the sun. It is equal to 365 days, 5 hours, 48 minutes and 46 seconds, or 365.24219 days.

If all calendar years contained exactly 365 days, they would drift from the actual year by about 1 day every 4 years. Eventually, July would occur during the northern hemisphere winter! Wouldn’t that be weird?

To correct (approximately), we add 1 day every 4 years…resulting in a leap year.

By making most years 365 days but every fourth year 366 days, the calendar year and the actual year remain more nearly in step.
