      on the ruler $AB\infty{_1}\infty{_2}$ , raises divider ADC where AB + AB = AC, ruler sets the angle $\alpha$
      semi-line ruler $B\infty{_1}$ sliding on point E , the point A of ruler slides semi-line l , when point C is on the line n , we get the radius of the circle , we get the angle $\beta$
      we have solved the tricection of any angle

      we need a section entitled "Archaeology". I have a topic I'd like to discuss, and not certain where to put it. In the meanwhile, where should archaeology topics go?

      info re Boris 2:
      When we recognised each other a couple of years ago on this forum, we decided not to carry our baggage, to this forum. So far, I have stood by that.
      Shame that Boris has seen the need to discredit himself on that point.
      Info re that forum can be got from James, who was a moderator on it.
      Boris, also on that forum, five or six, operational handles: What that may suggest, I'll leave to you.

      Hi, I liked your summation of Paddoboy. I agree with it. I have known him since the early 2000s, from another science forum. He started off ok and slowly got more abusive, cos that is what he is, over the years. He likes it on sciforums because he gets away with his style. You wont get anywhere arguing or telling him his faults. He spoils science as far as I see it.

        1 Thessalonians 5:9-11

        For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, who died for us, that, whether we wake or sleep, we should live together with him. Wherefore comfort yourselves together, and edify one another, even as also ye do.

        As for a scientific example, it's not enough (sometimes not even proper) to baldly claim "you're doing it wrong"; the best way to make your claim to better insight is to do it _better_.

      rpenner, why don't you end all the bickering and just tell the half-dozen posters that the Galileo analysis is legitimate?

      Uh... I've been drinking and and really don't care 'bout a lot of things...

      Hence, did you receive an email to something of the above. I think you know more than a bit about Mathematica. Wasn't going to make a thread since it would be like advertising.

      Hi,

      I have read some of your posts and would appreciate any involvement in our
      new science
      and philosophy forum.

      We are 100% Not for profit ... All ad revenue will be only used for human
      development
      we are going to use our forum as a way to bring together the right kind of
      people to not
      only discuss philosophy and science but to establish an organization of
      businesses that use all revenue to empower the right kind of people in this
      world.

      We would be very grateful for any involvement.

      Thanks

      Its sad to see the forum die like it is.
      I have been away for ~2 years, and i come back to see the forum in a terrible state, getting worse by the day.

      It would be very helpfull if you could offer some kind of an explenation as to your actions concerning the forum.

      Thank you for reading at least.

      Hi, a bot called 'filet' has spammed a new thread (Romanian Drug/Credit card scam) every 90 secs for the past 2 weeks. The forums IS nearly dead as a result as its posted threads in all the sections and just keeps posting. Its spammed 6824 threads since 5th Jan. Please BAN it and give your admin passwords to someone trustworthy.

      Hi, the Forum (THE FORUM) is nearly dead due to bots spamming non-stop every 90 seconds starting a new thread.

      You could at least give your admin passwords to someone else trustworthy so that they can at least clean it up somewhat and stop the bots from spamming new threads.


      For all The friggen BANS that you have given out over the years to EVERYONE, it comes as a damn surprise that you would just let it go like this.
