BRAINY QUESTION

[SUBHAJITRAHUL]

SUPPOSE WE DRAW A LINE ON EARTH SURFACE,IT IS CALLED STRAIGHT LINE,,BUT MY QUESTION IS EARTH IS ROUND SO WHEN WE DRAW THE STRAIGHT LINE ,IS THAT LINE CALLED STRAIGHT OR CURVED?
IF CURVED THEN WE HAVE NO CONCEPT OF STRAIGHT LINE,WHY?
AND THE MAIN FACT IS THE NEWTON'S FIRST LAW IS WRONG...??????

What has Newton's first law got to do with the curvature of the Earth?

[rojash]

I can't see any connection with Newton's First Law

:c)

I do love titles like this

"Hey everybody listen to me I'm about to say something really clever....."

You just wait with baited breath for it don't you?

[bibblebub]

and has WH Smith been selling bent rulers all these years?

[SUBHAJITRAHUL]

IF NO CONNECTION THEN IT IS TRUE THAT WE HAVE NO CONCEPT OF STRAIGHT LINE?

[baza]

we may not have straight lines but most of us have UPPER and lower case on our keyboards.

[jake-the-peg]

No the point is precisely the opposite

A perfectly straight line is a theoretical mathematical construct live an infinitely small point.

In physical reality a perfectly straight line is impossible there will always be some tiny fluctuation if just from gravitational effects.

But even mathematically a line drawn on a sphere is not straight in 3 dimensions - clearly look at it from above

It might have a projection in 2 dimensions which is stright though

SORRY HERE I DIDN'T TELL ABOUT KEYBOARD...MR.BAZA

[SUBHAJITRAHUL]

BUT WE DESCRIBE ALL MATTER OR THING BY 3 DIMENSION..

[ChuckFickens]

Please stop SHOUTING.

[SUBHAJITRAHUL]

WHY?

[baza]

because you are starting to upset people .

[ChuckFickens]

Because it's against the rules.

POSTING IN UPPER CASE IS CONSIDERED VERY RUDE ON THE INTERNET.

It is like SHOUTING at someone

[SUBHAJITRAHUL]

OH I DON'T KNOW,BECAUSE I AM NEW USER AT THIS SITE

[jno]

at least jake's answered the question...

[SUBHAJITRAHUL]

no,,,jno

[Old_Geezer]

If you draw a line as straight as is practically possible on a curved surface then in three dimensions it will be curved. But in local terms the curvature disappears in the "noise" of not having anything perfect. Perfection is a concept only.

We can conceive something perfectly straight, and we can understand we are unlikely to find this in practice, even light will bend.

As others have mentioned, you appear not to go logically from this issue of straightness to Newton's laws. If there is a connnection we have not spotted then you will need to give us more details.

press the caps lock key to stop shouting.

Now, what on earth are you talking about? How does a curved line invalidate Newton 1?
