A long shot

[syncopator]

I recently came across an engineering web site, it may have been a supplier of tools or perhaps an individual's site, at the bottom of which after scrolling down was a collection of useful formulae and geometrical diagrams.

I'm sure that I added the site to my Favorites (sic) but I'm damned if I can find it.

Does anyone know what the site may be?

[alanstepney]

Lots of possibilities.
I can only list some that I have in my favourites.

www.calculatoredge.com/
(If there is a calculator they dont show, I dont know of it!)

shopswarf.orconhosting.net.nz/sindex.html
(Lots of unusual information there.)

www.myvirtualnetwork.com/mklotz/
(Marv's site is well known and contains many useful programmes.)

www.oldengine.org/members/diesel/Tables/front.htm
(Peter & Rita are best known for IC engines, but lots of other info too.)

Thank you Alan.

I've added those to my list too. However, none of those are the one I recently saw.

The formulae and diagrams were, as far as I can remember, a sort of afterthought, tagged on to the bottom of a page. The section was fairly long.

Obviously not what the OP was after, but this is an interesting one - not engineering specific, but pretty clever.

You can ask it silly questions, like "how many days since Einsteins death"

Or

"Integrate X + sin Y"

Or "242nd digit of PI"

It'll even attempt to work out the next number in a series!
eg "1, 2, 4, 8"

Generally if you can phrase a question properly it has a pretty good stab at answering it...

(seems to know most constants too).

That's an impressive site. Thanks for that.

It doesn't know where Jimmy Hoffa is buried though .....

So I asked for the tide tables for Mahon harbour. Replied,

'It wasn't near the sea or something.'

For accuracy, Mahon harbour is reputed to be second to Pearl Harbour.

Oddly, there is a tide.

What a load of old cobbler's.

This one's quite good as well

Goldstar,
By coincidence, last night I asked it for the time of tidal high water at a particular UK location. Strangely it didn't understand the question

Jack,
I was going to ask it about the nearest Friday to the first new moon in June.
It'll probably take till tomorrow- the 11th June .

Cheers

I wonder if it knows where my Simplex book got to?

[kwackers]

To be fair it does describe itself as a calculator - it needs to be able to parse the data, figure out what you want to know and calculate the result.
So, "how long to get to planet mars at 100mph" returns a result valid for today (174.5 years).
but "where is my aunt mables teeth" generally doesn't...

Although it does know the answer to the "ultimate question of life the universe and everything".

I think it's amazing, it's fairly early work too, imagine where it could be in 10 years time....
