Communication and Science
Single cell bacteria communicate by chemicals to change behaviour.
Multicellular organisms have been around for 1,500,000,000 years. To work together the cells have to communicate by chemicals. Internally this is called hormones. External this is called pheromones. More complex information can be transmitted through dance.
This is the most incredible video, I really didn't think I would see this in my life time, Your brain sends a signal to your nerve cells to squirt Calcium on your muscles. This unleshes nanomachines seen here. This is truely beautiful scientific work, being able to see the individual atoms. Thus you can see you use chemical energy transformed into electrostatic force to ratchet your musles.

Magnetic Field
Below is a spinning Magnetic star in the Crab Nebulae
This is a detailed site covering the science of the observation.This is seven shot taken over a year by the Hubble Space Telescope, then looped every 15 seconds
Below is a video tour of the space station, The gravity is still there, but there are no forces because every thing is falling at the same rate. Everything has the same Mass, but the Weight force is Zero.

About Me
- drhill
- I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
