We have been having some problems with spammers lately: they used the forms in the website to spam us, and messing up our databases in the process. The best way to stop this is to use a captcha system that makes you input a word read from a distorted image, but we thought it will be better (and easier for us, as captcha requires installing stuff in the server) to make you pass a quiz on physics… Hopefully everything will be fine.
Now you have to pass a quiz to contact us
