Looks like a letter T falling over....Other than that i have no idea...

Greek letter Lambda, used in Physics to denote wavelength.

rm beat me to it, also, that is used as the 'A' in the title for the game Half-Life.

Thankyou. I knew I should know it from somewhere. Now on with the maths revision....

:)

Logo of the gay rights group 'Lambda', usually rendered in a rather fetching shade of pink.

actually, everyone is wrong, it is a well disguised orange.

I thought it was the necklace-wearing cyclops having a cigarette.:D

/me thought it was a wine bottle

CAN'T YOU ALL SEE IT IS A FLYING MONKEY TIME LORD?

christ some people are stoopey..

Softly softly catches monkey...

ohhh. since it's not purple, or flying through my room, I didn't notice that part, however, I did notice that it was a time lord of some type.

The Half Life symbol..........

:p

actually it's a character from the Tengwar, the alphabet invented by John Ronald Reul Tolkien, an approximation to it's sound would be an "h". :D

trust me, i once learned how to write with it.

Are you guys blind? It's Gillian Anderson.. Geesh.

:rolleyes: :igor:

Also used in matrix operations that involve extracting eigenvalues and eigenvectors. It makes no difference really, it's just a symbol used to represent a variable.


Er, no.... I think that the Greeks got there first....

All I can tell you is I never see it in porn:p

Which version of Tengwar did you learn?

ok, ok, ok. I'll rephrase. it's a character from the alphabet, this particular one is obviously not invented by tolkien, but it is used there.

bilbo, i leanrned the one contained in Appendix E to Return of the King.[edit] with the translation in the following paragraphs, first row, first collum representing the "t" sound, first row second collum representing the "p" sound, etc.[/edit]

Ahh,cool.

You can take lessons in elvish. i would like to, but all the courses are in the US as far as i can make out. i have downloaded some though.

ok here's another for you. what is..
It's something to do with differentiation and integration (I am vising these now, as in I haven't learnt it before :rolleyes:)

A black line.

Thanks bilbo I knew it was simple ;)
The full thing it's used in is attached if that is any help.

I'm sooo screwed for this exam

it is quite simple really.

The symbol is used in calculus to denote an integral. It is derived from an elongated 'S' and was originally devised by Liebnitz to indicate the 'Summation' of many small parts, the dx's or delta x's.

In this case the sign is used to denote definite integration, that is between definite limits, as shown by the super/subscripts attatched to it. The symbol is elongated for this very reason, to keep the super/subscripts clear of the function itself.

Delta is taken from the Greek alphabet and used to denote a small change, in computing it turns up as the name given to a type of compression used for movies or animations, and works by saving only those small changes that occur from frame to frame.

This is no place for a crash course in calculus I'm afraid :)

Thanks ujay :) 3 bloody text books and non of them says what it means :hang:

wait..is that not the mathamatical equation for ******?

This forum is already full of strange characters :p

If anyone knows where these are used, I'd be grateful for info:
Þ
§
¤
‡
±

:)

:Þ i think the second is an accounting symbol of somekind and as for the third http://www.carbon20.com/naoneo/board/index.php?

I think the last one is a plus/minus sign, like sqrt(4)= (plus/minus sign) 2.

§ - "section of", also the monetary unit of Sim City 3000 :-)
± - as deadrabbit pointed out, plus/minus

Crosshairs. :D

here's a good list of what the characters are:

/me makes teh 'blibber blibber' noise that comes from sticking your lips out, humming in a slightly high pitch, and moving your index finger in such a fashion to create said 'blibber blibber' sound...


roll out!
roll out!
