After 20+ years as a polymer chemist I have gathered a ton of information on various materials, some of which is info on elements. It started as a project about biopolymers at work, but limitations is one thing I don't do well, so I started collecting and structuring all sorts of material data as I came across them. The info on this site started out as a part of the site Pilgaard.info, but after 10 years on that site, I found it better to move the pages to a dedicated site, and here we are!
Why am I wasting my time doing this?
Because it matters!
Accessible knowledge matters!
The World is filled with all sorts of religious and political nuts spewing hate and lies, and lots of information is hidden behind paywalls making it inaccessible unless you have money. Keeping knowledge from the general public is a way of maintaining power, and it works. People will do insanely stupid things an kill others to maintain some belief or power structure, even if it keeps them poor and/or miserable, because all they are being fed is a slew of lies and hate. Making knowledge available is one way of enabling people to make informed decisions and help those who want to, to move forward. It is not the only solution, or a solution on its own. Most importantly, it is not a quick fix. It is only a part of the solution, but somebody's got to provide this part, and this is a part of my contribution.
Free education here in Denmark made it possible for me to get a good education, because I used the chance offered to me. Other countries don't have that kind of options. There you have to be rich, connected or excel at sports to get an education. I would prefer if people got an education because they were willing to spend the time and effort getting it. Offering free knowledge and educational material is one way of helping out, and where I can make a difference, so that's what I do. On this site and all the other ones I've got.
Anyway, thanks for visiting the site. Hope you found some useful information.
