You know, I just had a thought.( don’t look so surprised ) We think of stone age peoples as less technologically advanced than say iron age peoples. But… what we see in these unique hunting tools is the employment of structural properties similar to the current use of Kevlar and other modern day cutting edge technologies. Perhaps it is foolish to look at technological advancement in terms of metal.

are you looking to test what is sometimes called mental hardness? pretty sure it's not gender related. just look at those "survivor" shows.

Oh sure. But “we” don’t want to kill a fly with a hammer. We want the most efficient and intelligent solution.

At the moment I'm waiting to get a spare half hour to play around with the idea of an isosceles triangle projected out the side of our starting triangle. I need to do it with a ruler and protractor to see if there are any obvious relationships. I think this is going to be the approach the designer of the question had in mind. or not...I'm just guessing at the moment.

it's unlikley, but perhaps..... What makes you think that they could contradict?

Oh good, because I thought somehow it was exempt.

huh? is QM not a subset of GR?

vote! poll! the winky winky toy/creature thing stays where he is.

Isn't everything relative in QM? Isn't that the main point?

Yea I know what you mean about the seemingly fantastic amounts of data stored in the human brain. It sure seems like a big number to fit inside a small enclosure. And what does it all do. I figure it was mostly set up to get the better of the environment, enabling us to get food and stop being destroyed and thus reproduce. In order to do this we must be able to predict all sorts of things about the physical world, and worse still be able to predict the behaviour of other complex creatures like ourselves. It’s a big ask, so I guess complexity is to be expected.

Wasn’t the roll of women in Art one of inspiration?. I seem to recall many artists having a female muse.

The study of handwriting as a scientific tool is a sort of well known pseudo science. think it's called Graphology or something like that. it was pretty popular in the Victorian era. and Phrenology. I had a good look into it some years back. Personally I have many handwriting styles, and swap between them continually. Its just a skill anyone can learn. I was taught the traditional styles as a child by a professional calligrapher. it's a sort of rhythmic instinctive thing that you don't forget...kind of like swimming? First had to learn the Roman styles by copying the Trajan column inscriptions. http://penelope.uchicago.edu/Thayer/E/Gazetteer/Places/Europe/Italy/Lazio/Roma/Rome/Trajans_Column/inscription.html I have taught under fives perfect calligraphic style. A flat nib helps. They seem to take to it naturally. If you want fantastic handwriting, enrol in a calligraphy class and swap that ballpoint for a higher quality pen. http://www.sanders-garrett.com/weddings/envelopes/spencerian.gif

re the main topic. Word on the street is that the free radicals that are being targeted as the main cause to ageing, can be combated by the increase in a particular mitochondria - has worked in other species but not yet tried in man. Sorry for the loose details but I read it quickly as I passed a magazine today. 100 years old was the predicted achievable target. Believe it or not?

Ok….. I have had a quick play with this on paper. Nothing normal works. I’m gonna start extending out the lines past the main ABC triangle till I can see another triangle that I can work with. (this is good brain exercise.)

yet my instinct tells me that: the person who devised this problem wanted us to use (the fact that three angles of a triangle must add up to 180) and also make us do (a paradigm shift in the way the problem is being viewed). Hmmmm. is there any way to slide one of the triangles over to get a 90 degree total somewhere??

Agree. kick start your day with exercise. the body hates inactivity.

Oh sorry, Ali is short for ALICE. AIML type, by Dr Wallace.

Oh , you may be right, I just get some idea that this is the way to do it. when I get a spare second I will get a pencil and paper and nut it out. I was thinking maybe the fact that both sets of angles must equal 180 degrees…maybe some sort of simultaneous equation. Forget it until I try a few drawings. I'm sort of thinking something like x+w+20=180, and X+Y=140... and substitutions and that sort of thing?.

Yes do it that way, why make life hard. So now are you able to put those two angles and your removed DE line back on your diagram.

I think this has gone on long enough. We must become more creative to solve this puzzle. Can you kidnap a pet from the originator of the puzzle and extort the answer out of him that way?

Yes! The three big ones. Can you use Pythagoras to work out the Two unknown angles? I mean. s=o/h c=a/h t=o/a

Yea I know, I just wanted to throw in some sense of the diversity of the insect kingdom in there somewhere. Those spike like structures protruding from the rear look like a starting point.

I know there are some forms of spider that simulate their prey. Perhaps it is a specialised spider, that preys upon mantis young?
