A giant is being built in Lund, Sweden - MAX IV

llustrations of MAX IV exterior, by Fojab.
In 2015, the MAX IV will be operational in Lund, Sweden. The goal is to be world-leading in producing synchrotron radiation for scientific purposes. When charged, particles like electrons and protons are moving close to the speed of light and are bent by magnetic fields –  synchrotron radiation is created. This radiation contains many different wavelengths but with diffraction grating you can filter out x-ray radiation, which is the prefered choice when probing materials at the molecular level.

By leading x-rays into different beamlines, scientists can use the radiation for their research. By manipulating gratings and filters, scientists can vary the x-rays and by doing so, examine their material in detail. MAX IV will help scientists in the following areas:
  • catalysts
  • batteries 
  • solar cells
  • LED
  • monitors
  • computers
  • cell phones
  • drugs
  • fuel cells
  • clays for water purification or storage of nuclear waste
  • artificial photosynthesis
Since 1987, MAX-lab has been using synchrotron radiation for studying materials molecule by molecule. When MAX IV is ready to use in 2015, it will also be possible to study chemical processes in real time.  

MAX IV will be used by various industries for targeted research and for basic research. It is in the areas of material science, biotechnology, and medicin that usable discoveries will be made.

Free online graphing calculator for math

When I was in high school we spent a lot of time in math class to draw the straight line equations and quadratic equations by hand. This to to study how a, b ​​and c affected graph appearance

With you can now do this directly in the browser and it's free too. Additionally, you can save your graphs if you register.

Powers of ten - from quarks to quasars and beyond

The very first webpage that I did back in 1996 was about powers of ten. Back in those days. you had to settle with a table when designing the layout. Today there are YouTube and Flash so the visual experience is much better.

from the movie Powers of 10. Webbpage:

Dr Quantum - Double Slit Experiment

Among the first thing you usually do when to explain quantum physics is to show the double slit experiment. It is usually considered very abstract. When Dr Quantum shows this experiment it's muck more visual.

Ruben’s tube - standing waves that makes the audience stand up

When I studied physics this experiment of standing waves was done with sawdust in a tube. Somehow, the impression probably would been even greater if I had seen it with fire...

The classic physics experiment involving sound, a tube of propane and fire. Created for Flash Forward 2006, but useful in any case where you are not allowed to have fire. I push through the tube 449 Hz then higher frequencies, then some jazz and then some rock. This is real life sound visualization.
