This interactive presentation has quite a lot of possibities. I haven't found time to describe them all, let be even finish the presentation itself.
Why don't you fool around a bit? You can always help us!

Some things one might miss

  • The top right readout is also a conversion tool. You can put any number in any field (f, ƛ or eV). The others will be calculated automatically and the whole presentation jumps to the new frequency.
  • If things change when you hover over them, try clicking them!
  • I want to see this on my mobile!
    Things don't line up perfectly.
    Yeah, I'm sorry for that. Positioning and layout is very difficult for this thing. It's not just a matter of responsive design. It's much more than that. I'm not sure if i will ever be able to get it that far. Feel free to throw me some ideas.
    Always welcome to give suggestions about this.
  • Did you know you can make your own additions? Send some data to me and I will integrate it if it fits the possible representations.

Help wanted

I could seriously need some help. Been creatig this presentation since 2003 more or less. Since Apple decided to get rid of flash, I had to remake it in standard web technology, which is far less good and fast.
Things I can use help with.
  • Making a help file
  • Aligning and laying out everything on the right place is quite hard. I need help with that. Especially on mobile, responsive desing. I'm not even sure the SVG/HTML combination is the right approach. Canvas better?
  • Scientific corrections. Not everything is exactly right and some things I cannot find on internet. The ranges of matter interactions for instance!
  • Helping make new divisions, like atom spectrum lines, other black bodies, completing air attenuation on other frequencies, regulations, etc.
  • Spreading the word! I am amazed that so few people, especially scientists and physics professors can't reach this presentation even when searching on google! Als linking to us will help. Thank you. I used to be on Wikipedia. But since the flash version has been abandoned, strict wikipedia editors threw me off.
