Happy Birthday to Rear Admiral Grace Hopper!
Hopper was a pioneer in the field of computer science. She was one of the first programmers of the Harvard Mark I computer, and developed the first compiler for a computer programming language. She is also credited for popularizing the term “debugging”. Learn more about this amazing woman here
Cats do this because its a hunting instinct to snap the neck of their prey.
*the more you know*
It’s a murderer instinct but holy shit it’s so cute.
Fun Fact: The little shaking move they do when they pick up toys in their mouths is the one for snapping necks.
This one’s actually for disemboweling. And it’s adorable.
The cutest murder machines ever.
i fucking love cats.

Are the Earth’s Magnetic Poles About to Flip?
by Megan Thompson
Three European satellites launched Friday on a mission to study why the magnetic field surrounding Earth appears to be weakening.
The four-year study will collect data and map the field, which protects the planet (and us) from solar radiation.
Scientists say the field’s strength has weakened by about 15 percent in the last 200 years.
The weakening could be a sign of “polarity reversal" - when the field flips end-to-end, turning north into south. The phenomenon occurs every 200,000 to 300,000 years. But the last time the field flipped was almost 800,000 years ago.
The magnetic field is believed to be generated by the Earth’s molten iron core. The field reaches thousands of miles into space and creates a bubble around the earth. It’s what makes compasses work, and aids everything from navigation systems to animal migrations…
