Influenza Virus Poster

Flu Virus Poster showing viral structure
I have just created a poster showing the structure and external appearance of the influenza virus. The cutaway image is labelled and there is a short explanatory text. The poster is designed to appeal to schools, universities, laboratories, doctors offices, GP's surgeries, chemists, pharmacies, and vaccination services. It is the latest in a series of science and math posters.

I have also created a series of products featuring my influenza virus.

The reason that influenza changes so rapidly (and why we need different vaccines each flu season) is that the flu genome is segmented. It comes in eight pieces. If a cell happens to harbour two or more different flu types, then new virus particles can assemble by including segments from different parent viruses. This is called reassortment.

Pythagoras' Theorem animation

Steampunk Pythagorean Engine
I have just finished a couple of animations showing Pythagoras' Theorem with the squares of a right-angled triangle animating as the triangle changes shape. One is a simple and conventional demonstration of the geometry, the other is a steampunk Pythagorean Mathematical Engine. You can also see a high resolution still of this Pythagorean Machine.

Cartesian coordinates animation uploaded

Cartesian Coordinates Animation. This brand new animation shows how Cartesian coordinates can describe a point along a line, in a plane, or in a space. This final still from the video shows a square sheet of paper with a grid pattern of fine blue lines, a central red point (origin), X, Y, and Z axes , and two points. The two points (shown as coloured spheres) have their corresponding positions marked along the axes. Shadows of the purple point (floating at front) are cast on each of the three perpendicular planes. This helps to explain how the three coordinates (x, y, z) can specify a point anywhere in three dimensional space. All sorts of useful mathematical operations can be done using these coordinates. This animation is designed to help those who are new to this subject to easily visualize and understand it.

There are several high resolution Cartesian coordinates stills from this model available.
