This (https://cbraungardt.com) is a personal blog and the product of my experience, research, conversations and, quite possibly, occasional mistakes. If you read and use information from this blog, then it's at your own risk. Unless credited with a citation, I only publish my own images and words, so please note that I hold the copyright for all the material and you cannot use it to reprint or publish without my written consent. Now and then, I might change the topic of my musings, edit previous posts, or even change my mind - I consider this a natural consequence of having an open and curious mind.
