"You must learn to talk clearly. The jargon of scientific terminology which rolls off your tongues is mental garbage." -Martin H. Fischer I've always thought that the Universe is absolutely amazing; that everything from the tiniest indivisible particles all the way up to the largest structures and superstructures making up the Universe has an amazing story to tell, if only we can figure out its secrets.

"Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people." -Carl Sagan Our night sky, quite literally, is our window to the Universe.

In fact, practically…
Our teeth are a mystery. The set we grow during late childhood stays with us throughout our lives, biting and chewing thousands of times a day. They can withstand forces of up to 1,000 newtons and yet, the material that coats them - enamel - is little tougher than glass. How does this extraordinarily brittle substance not shatter into pieces every time we crunch a nut or chomp on an apple? Herzl Chai from Tel Aviv University found the answer, and it's a surprising one. At a microscopic level, our teeth defend against fractures by developing with cracks already built in. These pre-made…

Recently Soulcatcher Studios, the site that is running an expanded version of that slide show, has a portfolio of the lovely, strange, and arresting 1928 master work of photographer Karl Blossfeldt: Urformen der Kunst, or "Art Forms in Nature." Karl Blossfeldt (1865-1932) was a German instructor of sculpture who used his remarkable photographs of plant studies to educate his students about design elements in nature. Self-taught in photography, he…
