let students explore concepts by manipulating an expression—or a graphical representation of an expression—with things like sliders, buttons, and checkboxes. When you wrap the Manipulate command around an existing calculation, Mathematica automatically creates a sophisticated interface that lets you and your students change values and see what happens in real time. It’s truly empowering! Now students can interact with everything from two-dimensional trajectory paths… to Riemann sums… to the phases of the planets… to almost anything else you can imagine. See the Wolfram Demonstrations Project for thousands of free ready-to-use examples.

let’s say that one movable synapse could store one byte (8 bits) of memory. That thimble would then contain 1,000 gigabytes (1 terabyte) of information. A thousand thimblefuls make up a whole brain, giving us a million gigabytes — a petabyte — of information. To put this in perspective, the entire archived contents of the Internet fill just three petabytes.

"We may not have created a black hole, but it seems we may have discovered a way for elementary particles to shape the path of evolution. You just never know what you are going to find"

Anti-gravity papers are routinely rejected from peer-reviewed journals, and scientists who propose anti-gravity quickly lose their funding. Universal gravity theory is just a way to keep the grant money flowing.
