Important Announcement!

Just added a link to some solutions provided by Bud Simrin and some others by Sebastian Bodenstein.  The links are near the yellow highlights just next to the images of the RTR book cover.  Thanks Bud and Sebastian!

  1. Hi, I was just browsing your solutions website in order to collect solutions for Penrose's RTR book and thought you might want to know that RoadToReality.Info expired on the 23rd of March and that the owner apparently hasn't renewed it - which means that the domain is probably pending deletion within the next few days unless the owner makes a surprise late payment before then. This would therefore be the right time to save these solutions, in case you want to keep them from disappearing from your collection.

    1. Thanks for letting me know about this, but it seems to be working OK again now. Is it working for you?

  2. Just in case, I have downloaded ALL of those solutions to my hard drive. Of course if the original site goes down, my solutions are not necessarily organized and I have only downloaded random files from the discussions.

  3. All I can say is that I am in personal contact with the owner of the site and I know that he intends to keep the site going indefinitely. Obviously this is not a 100% guarantee.

  4. Took me a year and a half, but I finally have a complete solution to Problem 13.7 involving normal subgroups of the Lie groups SO(3) and O(3). I also decided my problem solutions would likely be easier to access and endure much longer by uploading them to GitHub. So, a better location than my Dropbox site to grab them from is https://github.com/matrixbud?tab=repositories. My free Clifford Algebra package for Mathematica can also be downloaded from there. Vasco, if you get the time, you might want to change that link.

  5. Dear guys. I am very recently reading RTR and following the solutions to the problems. It is amazing the great job you are doing.
    The case is that since a couple of days the links to http://roadtoreality.info/archive are broken. Could anybody fix that? Thanks

  6. It's true, the site is down. I'm not a mathematician but i found RTR book very interesting. However i'm not able to solve all those exercices. It would be pity to lose all that great effort, that intelectual inheritnace. You,ve got a lot noncence nowadays in media, that site was quite opposite :)

  10. Hi, I don't know if this is still an active page, but it seems that as of this month, www.roadtoreality.info is no longer working. I just get a "Sorry... www.roadtoreality.info could not be found." whenever I try to access one of the solution pages from there. I know it's not your website, but is there anything that can be done?

    1. From matrixbud: Use Vasco's blog when it is up. When not, you can use my Dropbox shared site: https://www.dropbox.com/sh/gsr00wgzdox296l/AAAPKN5HP0qGZxx5MANcsBhCa?dl=0 and there are additional solution on my github site: https://github.com/matrixbud?tab=repositories

  11. Hi, just noticed that the links to the roadtoreality.info page are not working. But www.roadtoreality.info is instead working!
    This link works as well http://legacy.roadtoreality.info/
    cheers
