- 400x Magnification of Stagnant Rain Water I bought a new Compound Microscope with upto 1600x Magnification. So I decided to put it to use. After collecting some stagnant rain water from the side of the street I used my Samsung 5.0 MP camera to record a video of what I saw at 400x Magnification. I would of did a larger magnification but the light going through the eyepiece is not sufficient at larger magnifications. I do not know the species in the video. Please remember this was all filmed through the eye piece so the quality is what it is. I hope to post more videos of the micro-world i hope to discover on my on.

- Deep Mandelbrot Zoom , final magnification 2^838 . This is the deepest zoom I have renderd sofar. I first rendered this in 2002. But I recently remade it with nicer colour rendering. It goes very near the the left tip of the Mandebrot Set - so it does no look quite like the ordinary zoom sequences you see. One problem with really deep zooms is to get to some interesting point without hitting "the computational wall". Ie The computation takes "forever". If done on a single computer it would take about 3.5 years on a 1 HGZ Athlon Thunderbird, and on a 2x2HGz Core2Duo about 1 year (assuming 32 bit code). If on the other hand you would do this on 25 MHz 386 sx:es you would have to have 135 of them running continously from 1990 until now. Cost for electricity (assuming 50W / machine) would be close to 1.1 million SEK or 150000 USD with current prices. Well of course you would have plenty of time thinking about optimizations :-)

- Mandelbrot set deep zoom to 190 trillion magnification factor The Mandelbrot set, a wonderful illustration of how simple rules can lead to great complexity. The Mandelbrot set is a mapping of the complex plane into itself under z = z^2 + c, and that's it! Iterate every pixel until it diverges beyond a certain radius (minimum 2) and then shade the result based on the number of iterations that point took to escape. Points that do not escape are coloured black. Each image in this movie was contrast stretched with 2% clipping of the shadows such that the region around the prisoner set is clearly visible at all times. A 0.1% clipping of highlights was done to ensure that there is always some white in the image to maximise the dynamic range. Furthermore, each image was supersampled 4x and then bicubically interpolated during shrinking to prevent nasty jagged edges. Computation time was somewhere around 30hrs. At the end you will see what happens when the limit of 64-bit double precision is approached....! Enjoy and be mesmerised! For those who wish to replicate this, the complex coordinates (x + iy) of the final viewport are: Top right corner: -0.784345314119042 + 0.146482382083744i Bottom left corner: -0.784345314119062 + 0.14648238208373i zoom factor: 1.0138 The viewport centre was kept fixed (just a straight zoom).

- Carbon Fiber *I do not own the rights to this video. This is not my video. I got it from to share here on youtube. Explore the inner compounds of a carbon fiber. Carbon fiber is the common name used to refer to plastic reinforced by a graphite textile. Less frequently, the term is used to describe the textile itself, but it is pretty much useless unless embedded in plastic. Carbon fiber is known alternatively as carbon fiber reinforced plastic or carbon fiber composite. Carbon fiber is very expensive, but has a fantastic weight-to-strength ratio. Attempts to put it into mass production have so far failed, due to inadequate demand, the customized nature of most carbon fiber parts, and a lack of skilled craftsmen. The material is employed in high-quality cars, boats, bicycles, and planes, including popular Formula One racecars. Depending on the orientation of the fiber, the carbon fiber composite can be stronger in a certain direction or equally strong in all directions. A small piece can withstand an impact of many tons and still deform minimally. The complex interwoven nature of the fiber makes it very difficult to break. In terms of weight-to-strength ratio, carbon fiber composite is currently the best material that our civilization can produce in appreciable quantities. Introducing carbon nanotubes into the fiber is currently in research stages, and may offer improved ratios of 10 times or greater a space age material indeed. Carbon fibers are chemically grown on ...
