Descartes

This is a Windows application for drawing graphs of mathematical functions. See screenshots below for an idea of what it can do. You do not choose from a limited set of offered functions - an expression evaluator can deal with an extremely wide range of expressions from simple polynomials, trigonometric, hyperbolic, exponential terms, differentials and integrals, and sums and products of series.

This rubber band propeller airplane kit is from Yoshida in Japan. The Hishou, with its 2 reverse propellers, dates from 1911, when it crossed the Sumida River in a model plane contest. The kit uses balsa wood, ultra-light Styrofoam, rubber bands and 125mm reverse pitch propellers. Illustrated instructions and glue are included. The kit is packed in a box with appealing graphics in Japanese and some English.

There is also a version called the ‘Crow‘ that only has one propeller but it’s still a classic design.

How often have you thought to yourself “I wish I had an ice cube maker?” I’m going to guess that most of you won’t have ever had that thought. It’s understandable, since practically everyone owns a freezer, which makes ice cubes. However, if you need a lot of ice in a short while, you’ll be disappointed. This is why the Ice Cube Maker Machine was created.

This simple device can freeze up a dozen cubes of ice in just 10 minutes. When you’re serving a lot of guests at a large gathering, a steady supply of ice is always needed. It accomplishes this feat by utilizing a highly efficient compressor which can freeze at much faster rates than a regular freezer. You’ll also be happy to note that it is a low-noise machine, so your guests won’t be bothered by any loud humming noises.

In Arizona State University camera orbiting Mars has uncovered salt deposits on the cratered Martian surface, suggesting water was once widespread on the Red Planet.

Scientists say the more than 200 deposits likely formed through water evaporation and could be ideal places to look for past life because of salt’s preservative qualities.

The findings are being published Friday in Science magazine.

If you can, imagine a vehicle that runs on air, achieves over 100 gas-equivalent mpg and over 90 mph, has zero to low C02 emissions, seats six, has plenty of space for luggage, cuts no safety corners, and costs no more than an average economy to mid-size vehicle.

This is the expected performance of the revolutionary compressed air vehicle that Zero Pollution Motors (ZPM) is introducing to North America. The vehicle is powered by the Compressed Air Engine (CAE) developed by Motor Development International (MDI), a 15-year old company based in Nice, France, and headed by inventor and Formula One race car engineer, Guy Negre. ZPM is the exclusive representative for MDI in the United States.

Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer’s sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal - which can be music, speech, or output from an electronic circuit. Zelscope features the interface of a traditional oscilloscope, with conventional gain, offset, timebase, and trigger controls. As a real-time spectrum analyzer, Zelscope can display the amplitude and phase components of the spectrum.

Check out the What is beyond Super Nova The end of Star! Our sun will find the same fate some day….

.. The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.

Unlike most planetarium software, Celestia doesn’t confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A ‘point-and-goto’ interface makes it simple to navigate through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that’s not enough, you can download dozens of easy to install add-ons with more objects.
