# Anyone Enjoy Euclidean Construction Puzzles?

11/02/2017 10:05 AM

I just came across this game called Euclidea: available on PC, Android and Apple.

It's really great (if you like this sort of thing).

I'm really impressed with the implementation on Android for small screen and inaccurate pointer.

Several of the constructions have more than one solution: a straight forward one, and, one which is much simpler, once you know the trick, but, difficult to discover.

Don't be tempted to look for the answers on YouTube you'll get far more satisfaction discovering them for yourself.

One final thing: some of the problems give you extra points for simply duplicating an answer with for example a mirror image. For example you're asked to construct a 30° angle at a point on a given line: you need to construct the angle above and below the line to get all the points, and this is not obvious from the way the question is given. You need all the points to unlock later games (unless you want to pay).

The 30° angle is also a good example of the "straight forward" and "easier when you know how" questions.

I have been fooling with this. Totally addictive for a math geek as myself (with my limited mathematical language ability). Only got as far as the inscribed circle on square. Just as my dad always taught me: "You can't fit a square peg in a round hole".

Do you have a live link that works for that one?

Tried it, but it didn't work in preview so I bailed and put in the link.

You sure that isn't the Church of Christ, instead of the Mormons?

Now, I am gonna get it for sure.

After making this statement, Slartibartfast was asked, "And are you?"

Was Slartibartfast unhappy, or unright? We still don't know. I suspect both.

I would rather be half-fast and mostly right, than way fast, and totally wrong.

Either end, either way. It is donkeys all the way down to the turtles.

The exchange went as such:

Slartibartfast: "...I'd rather be happy than right any day."

Arthur: "And are you?"

S: "Am I what?"

A: "Happy?"

S: "No."

Only in the book. In the radio scripts it's:

SLARTIBARTFAST:
Maybe. Who cares? Perhaps I’m old and tired, but I always think that the chances of finding out what really is going on are so absurdly remote that the only thing to do is say “hang the sense of it” and just keep yourself occupied. Look at me, I design coastlines, I got an award for Norway. Where’s the sense in that? None that I’ve been able to make out. I’ve been doing fiords all my life, for a fleeting moment they become fashionable and I get a major award. In this replacement Earth we’re building they’ve given me Africa to do, and of course, I’m doing it will all fjords again, because I happen to like them. And I’m old fashioned enough to think that they give a lovely baroque feel to a continent. And they tell me it’s not equatorial enough… what does it matter? Science has achieved some wonderful things of course, but I’d far rather be happy than right any day!
ARTHUR:
And are you?
SLARTIBARTFAST:
No. That’s where it all falls down of course.
ARTHUR:
Pity, it sounded like quite a good lifestyle otherwise.

Ah, yeah, it's hard to keep track of how the conversations go down in the various media. Every version is different, in some parts only slightly, in others quite wildly.

Revisionist history is a problem, even when it's the original guy writing all the revisions. We need some truth in history.

What is truth? (You had to know that question was coming)...

I suppose truth is what tastes better than real truth and without the bitter aftertaste.

Why? Truth is as it comes. Straight from the bottle, whether pure water, or Bourbon, these are true to their identity.

I am asking a more general question: What is truth? Johnny Cash sang about it, the Bible tells of it...what are the other sources we can point to and say, "this is truth"?

What is Truth? First you have to ask "Who's Truth?"

The Romans wrote of the invading Germanic Tribes sacking their northern borders mercilessly during the era that turned out to be the Fall of the Empire. The Germanic tribes, however, saw themselves as refugees, not invaders, seeking shelter and space to live as they were fleeing the conquest of the Germanic lands by the Hun Horde invading from the east.

What we know is often incomplete, and it's likely that we only hear one side of a story(1), so when a source of information claims to be unalterable, untestable, unfalsifiable, Truth, there should be immediate suspicion. All that is knowable can be measured, in some way, to varying degrees of accuracy. If a thing can be measured, it can be tested, and only those things than can be tested and proven not to be false should be accepted as Facts.

Science deals in Facts, the concept of Truth, being a thing that is considered right even though there is no means to measure or test it to see if it is false, is better left to the poets and philosophers.

Notes:

1. We seldom hear the story of the Herbalist who lives by herself in the woods, minding her own business until a pair of bratty kids show up, vandalize her house, subvert her attempts to get some chores out of them in compensation for the damage they caused, and finally shove the poor woman into her own oven and roast her alive. And this woman's only crime was being knowledgeable about local flora and having a desire to teach these children some responsibility for their actions through a quickly-devised 'scared straight' program.

I suspect that with a mind set such as that, I should not ask you "What is Truth?".

Pontius Pilate asked a similar question to Jesus Christ, as you may or may not recall.

Even you will have to give way to the voice of youth, crying, "What is Truth?"

It is appointed, just as is the end of my days, and your days.

And as you may remember, When the crowd called for Barabbus to be freed, Pilate said, "Are you guys sure? The guy you're picking is a liar, a murderer, and a thief. This other one has only been going around saying "let's all be nice to each other," and making civic leaders look like idiots, but neither of those are actually crimes (especially if those 'civic leaders' really ARE the idiots I know them to be). Are you guys REALLY sure you want Brarabbus back and not this Jesus guy? ... Fine, you get Barabbus back in your community, so what do you want me to do with this guy? ... Cruci-WHAT!?!?! Is this a Roman court or a lynch mob? Fine, fine! You people will get what you want, but I'm washing my hands of this whole sordid affair."

After that, who could blame him for saying, "What does 'truth' mean any more when people won't even listen to simple facts, and the mass media tries and convicts people even before they get their day in court? Is it even possible to tell truth from lies, fact from fiction, in these mad times?"

Pilate was essentially locked in by events, and even this fulfilled words from a prophet.

The thing that matters now: what will you and I do with this Jesus of Nazareth?

I would prefer to be in that church, with the true believers.

By the way, kudos to the local man that sought out the assailant last Sunday, ran to the danger, and stopped the attack when he did. That man is a hero in my book.
