  Total Solar Eclipse
Total Solar Eclipse

  The total solar eclipse of February 26th, 1998. Pictures taken from Seroe Colorado, Aruba. This picture shows the full view of the corona. more  
T-Rex
Tyrannosaurus Rex

Tyrannosaurus rex is one of the biggest dinasaur meateaters. It ate other dinosaurs for lunch. It was taller than three men standing on each other's shoulders. Its teeth were 6 inches long and it could crush large bones when it ate. more

Nanobes

Nanobes have cellular structures similar to fungi and spores but they can be 10 times smaller (20nm-1.0μm). They have hollow, membrane bound structures that are most likely composed of Carbon, Oxygen and Nitrogen. more

Supercomputer
Cray 2

In 1985 Seymour Cray developed the Cray-2, which was even faster (1,200,000,000 calculations per second). more
Mandelbrot's fractal
Mandelbrot's Fractal

The Mandelbrot set (the black points) are the complex numbers C for which the sequence Z0=0; Zn = Zn-12 + C remains bounded. The surrounding points are colored to represent the different rates of divergence of the unbounded sequences. more
Particle Creation
Particle Creation

In physics the The Standard Model theorizes that all the known matter particles are composites of 6 quarks and 6 leptons, and they interact by exchanging force carrier particles. more

Buzz Aldrin walks on the Moon
A Space Walk

'Drifting right' I called, watching the shadow of the footpad probe straining to touch the surface. 'Contact light.' We settled silently onto the moon with perhaps only 20 seconds of fuel remaining. more

Typhoon from Space
Typhoon from Space

The winds of a hurricane are structured around a central "eye", which is an area that is free of clouds and relatively frid calm. Around this "eye" area, storm clouds wrap in a counter-clockwise motion. more
