Planck's constant is one of the fundamental constants in the universe. For example, it defines the relationship between the energy of, say, a photon and its frequency. It's widely used in the mathematics of Quantum Mechanics. Recently, using just a Lego kit and some other equipment, including a laser, Leon Chao at the National Institute of Standards and Technology in Gaithersburg, Maryland, showed how to make this measurement. This is for real, and it works because the experimental technique simply requires a well crafted balance. It's all written up in the M.I.T. Technology Review. You could actually do the experiment yourself because the costs of parts is only about US$500. Very cool.

Apple's iPad sales have been declining. Everyone in North America and Europe who needs or wants one has bought one. Now, Apple is faced with the need to engage new, perhaps less affluent geographies.  But also, crucially, there is the business of getting the iPad on a path to more capabilities, growing with user needs and expectations.
