A group of scientists and food activists is launching a campaign Thursday to change the rules that govern seeds. They’re releasing 29 new varieties of crops under a new “open source pledge” that’s intended to safeguard the ability of farmers,…
With its 170 engineering and statistical functions, the TI-66 calculator was an indispensable piece of equipment for researchers such as Dr. Howard Nash, NIMH. State-of-the-art technology when it was introduced in 1983, the TI-66’s landscape orientation of the customary 14 arithmetic keys as well as an additional 28 keys for mathematical operations and programming distinguished this machine from its competitors. The TI-66 could be programmed to perform up to 512 steps. Programs could be written on the keyboard or loaded from a magnetic card; user-written programs could also be copied onto those magnetic cards for later use. TI also provided an optional thermal printer that could be controlled by the calculator keyboard.
Although it was a Texas Instruments (TI) product, it was built by Toshiba from Toshiba components—a collaboration to challenge Hewlett Packard’s (HP) successful HP-41 calculator. HP and TI each introduced a programmable calculator in 1972, the HP 65 and TI-52, respectively. Each of these calculators incorporated a small motor for passing the card by a reading device; however, the dimensions of the HP and TI programming cards were quite different. In 1977, TI introduced the TI-59, a calculator with increased ROM (read-only memory) which could be further enhanced by a plug-in ROM module. The TI-66 further improved the design, offering more programmable steps and more memory in a smaller package.
Bit late for this - a Ukrainian-style Easter Egg sculpture by Ron Resch made in 1973 was the first physical structure designed with 3D design software:
Though the surface area of an egg can be difficult to solve mathematically, the enigma of how to assemble two-dimensional tiles onto a three-dimensional egg was eventually solved by Ronald Resch, a computer science professor from the University of Utah, with the assistance of computer-aided design. It was the first physical structure designed entirely with computer-aided geometric modelling software.

Big changes are coming to Cerro Armazones, a remote mountain in Chile. Construction is about to begin for an area that will house the largest telescope ever constructed on Earth: the European Extremely Large Telescope (E-ELT). Yes, the name is sort of hilarious, but its not lying either. The E-ELT is going to be ten times larger than any other surface telescope and sensitive enough to be able to spot life outside of our solar system.
