For clarification...
Superman leaves the first train as it departs and flies continuously there and back between the two trains.

what a

beautiful mind

to have thought of this tale of two cities

i wonder how long it takes the trains to pass each other

nudge nudge wink wink

Why do people say "Maths" in stead of "Math"?

why do people say math instead of Maths? (Maths is of the correct way)

Why is maths correct? Isn't maths plural of math? What is the derivation of the term?

your langauge is english. The english version is maths.
Is Mathematic (singular) correct

Hi Mica - thanks for writing to Dr. Math.

Good question! Maths is short for mathematics. Here's what Steven
Schwartzman has to say in his book, _The Words of Mathematics_
(Mathematical Association of America):

mathematics: Latin mathematica was a plural noun, which is why
mathematics has an -s at the end even though we use it as a singular
noun. Latin had taken the word from Greek mathematikos, which in turn
was based on mathesis. That word, which was also borrowed into English
but is now archaic, meant "mental discipline" or "learning,"
especially mathematical learning. The Indo-European root is mendh-
"to learn." Plato believed no one could be considered educated without
learning mathematics. A polymath is a person who has learned many
things, not just mathematics.

"In English, the noun mathematics takes singular verb forms. It is often shortened to maths, or math in English-speaking North America." - WIKI

Apparently both are correct. And since I live in English-speaking North America, it's Math

( ........Superman has gone for a lie down !)

Rosborne, I think the major difference lies in the way in which it is taught. In the United States, we have separated maths into four separate and distinct categories - Algebra, Geometry, Trigonometry and Caluculus each of which are separate and year long courses. In the Uk - they combine them and so call them maths plural instead of one separate and distinct math subject, ie - a math , such as algebra, geometry, trigonometry or calculus (alone and separate from the others).

As one who was educated in America, I always say 'math'. But I certainly see the logic of 'maths' inasmuch as it's just short for mathematics.

Well, well : isn't oolongteasup's double witted quip about a movie and a novel a circumlocutory inverted quirk of a way to not answer the question by summing the series.

Butt out of it you hemi-parasitic predator and get a plant life.

That might be enough solipsistic lip and cogito ergo sums from you sister. Enjoy your reason and your season everyone.

From one point of view, Supes has flown for two hours at 1000 kph.

From another point of view, Supes ends up 400 kilometers from where he started.

You pays your money and takes your chances.

Meanwhile, the passengers and crew of each train are now a thin red smear from having instantly accelerated to 200 kph from a resting start.....

Superman would have to have zero mass, a final frequency of infinity and zero volume.

No problem for a being who in one story orbited the Earth "so fast he reversed time" in order to undo Lois's fatal car crash !
