Based on an idea by Omer Roucoux. Can’t learn chemical reactions? Don’t know how combining powers work?

Discover new ways of understanding, or teaching, chemical reactions.

In 1978, Omer Roucoux published this chemical jigsaw puzzle. It is available here in two parts, as a GIF and the original DrawFile version for RISC OS, which you can download separately.

Best results are obtained from the original.

ISO has just published a new version of the SI Guide, a small manual for the use of the SI, the International System of Units (Système International d’Unités).

The SI is a comprehensive metric and decimal system based on units and derived units. The seven base units are: length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

The 32-page SI Guide will be useful for many people including engineers, scientists, technical writers, teachers and students.

Here’s an interesting way to talk about Mathematics that’s different!

It’s one of many educational videos to be found on both YouTube and TeacherTube, a website dedicated to education via video.

We’ll bring you more later, but check the sites yourself, if so moved.

Just spent four days at the several Infrared Conferences that are part of the SPIE DSS meetings plus one of the world’s biggest Infrared & Optical Expos in the world. It was all held in Orlando Florida, USA at the giant Marriott World Center.

The Infrared Conferences consisted of ThermoSense XXX (The Industry & Research Applications conference), Infrared Technologies and Applications XXXIV and Infrared Imaging Systems: Design, Analysis, Modeling and Testing XIX.

ThemoSense was kicked off by the Fourth Annual Vendors Presentations & Reception on Monday evening and was followed by 13 Technology applications sessions ranging from Pyrometry to Image Fusion and NDE Materials Evaluation during Tuesday, Wednesday & Thursday.

{Click on Image to go to page with video}
Melbourn, UK — Velocity11, an Agilent Technologies company and pioneer in automation technology solutions for life science laboratories, has produced a new online video that demonstrates and describes its Bravo™ Liquid Handling Platform.

Its space-saving nine plate-position footprint can fit inside a standard laminar flow hood, enabling automated liquid handling for cell-based assays or hazardous reagent handling.

The Bravo utilises the proven high-accuracy pipette heads of the VPrep™ pipettor for dispensing from 100 nl to 200 ul in 96, 384, and 1536 well formats or to a single column or row of any of these plate types.

The deck is easily customised to meet a wide range of assays, with numerous plate pad options. Additionally, the unique, highly open design of the Bravo platform permits access from all sides for simple integration with other devices and unencumbered standalone use.

The goal of the SocialCalc project, as described on the Software Garden OLPC Home Page, is “to provide a capable, simple spreadsheet which runs locally on your computer”.

Software Garden is involved in the project of Socialtext, Inc., to provide a system based on a new version of the SocialCalc spreadsheet code on the OLPC XO-1 computer that is being called “SocialCalc” on the One Laptop per Child - OLPC initiative.

The main engine is written in JavaScript and is available under Open Source licenses. Much of the code, being written in a common scripting language, should lend itself to examination, reuse, experimentation, modification, and extension.

The latest version and its documentation is free and is downloadable from the page link above.

Can Or Box Pinhole Camera

Described in wonderful detail, the pinhole camera is an easy to make introduction to the world of photography as this page on the KODAK web site shows.

What is A Pinhole Camera. you ask?

It is simply..”a small, light-tight can or box with a black interior and a tiny hole in the center of one end. By using common household materials, you can make a camera that will produce pictures.”

You don’t even need a PC or a digital camera, just some simple tools a little film and some way to develop the film.
