Earth's Core Hotter Than First Believed

coreUsing a series of very technical tests, scientists from the French research facility CEA have determined that the Earth's core is roughly 6,000 degrees Celsius. That is approximately 1,000 degrees hotter than the temperature obtained by tests in the 1990s.

These new figures show that the center of the Earth is just as hot as the surface of the sun.

The experiment that supplied the new temperature used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt. The BBC reported that "To replicate the enormous pressures at the core boundary - more than a million times the pressure at sea level - they used a device called a diamond anvil cell - essentially a tiny sample held between the points of two precision-machined synthetic diamonds.

Once the team's iron samples were subjected to the high pressures and high temperatures using a laser, the scientists used X-ray beams to carry out "diffraction" - bouncing X-rays off of the nuclei of the iron atoms and watching how the pattern changed as the iron changed from solid to liquid."

Character: The Silent Students and...

  • Character is sometimes defined by silence as well as chatter. But often, chatter is more highly prized. I wonder what more we could do if we paused in silence to recognize the quiet ones among us?
  • For the silent ones, I remind you that loud and continuous talking is not the sign of intelligence. And, for the gregarious ones, silence is not the sign of untalented. Quiet doesn't mean: weak, easy, stupid, deep, sneaky, or aloof; noise doesn't mean: strong, dominant, brilliant,...

A Quote from Jim Collins for Leaders

  • "The signature of mediocrity is not unwillingness to change. The true signature of mediocrity is chronic inconsistency." As leaders, many depend on us in our roles to be the voices of consistency; but, sometimes that consistency may lead us to make decisions not in the best interest of our faculty or our students. These groups watch for consistency for everyone else but seek exceptions for themselves and their unique positions within the school.

New Year’s Resolutions of a Gifted...

As 2014 approaches, I wanted to reflect on my resolutions for the coming year. As a teacher of gifted, I thought it would be beneficial to share my goals and thoughts for the future as well as have other teachers post their resolutions here.

First, a disclosure: Im not that big on New Years resolutions since most people dont keep them, and I believe in allowing goals to come to mind at any time of year and acting on them when inspired. With that said, I still think the New Year...

Turning Bad Chinese Food Into Satire...


I find myself bewildered by the public attention that Patrice Wilson's work garners. Starting with Rebecca Black and moving forward, he's had sensation after sensation on YouTube. He has transformed the music video and pop-song landscape by generating millions of views, based on the fact that the work is intentionally cheesy and lacking in artistic integrity.

Despite his distinct formula and trademark, he attracts the same mega-hyped publicity and video views on YouTube...
