Today's findings....

i wonder if any one of you felt disloyal when not learning?

i experienced it today. i went to attend a workshop in school. it was basically for maths teachers, but they always put computer teachers with the maths group... so there i was ready to get bored (or so i thought) and waste my time (as a precaution i took a copy of reader's digest with me)but suddenly i felt disloyal to learning!!!!!! i felt as if i was not doing what i was supposed to do there... so i started paying attention and found out these things.

* a circle touching all the sides of a triangle is called an inscribed circle
*to draw means that we do not need compass and
* we are ruled by coordinates (here i forgot spelling of coordinates and wrote it with 'Q' and then i remembered that it's written with 'C'.
*space and time are coordinates
*if you cease the motion of earth the times stops
*time is the flow of events
*quantum mechanics says that if events stop taking place, the time will stop.
* speed is the way through which we can get free from the gravitational force.
* if you are unable to identify all the atoms of hydrogen, then you can say that they are symmetrical with respect to each other.
*global symmetry
*local symmetry
* global means universal
* local means [trainer to forgot to mention this]
* in theory of relativity time will lose its global symmetry.
* twin paradox!!!!! [to lengthy to explain here simply story of two sisters, one moving with the speed of light and one in the normal earth's circumstances... time - a fraction for one and ages for others]
* before big bang time is considered to be zero.
* invariant means never change!!!!
*The zero time is called 'Max Plank Time'
* there are three types of symmetries...
1. Reflected 2. Translated. 3. Rotational
* reflected means inverted by negatives, but the resultant is same. example ur mirror image. [trainer forgot to explain other two!]
* periodic functions repeat themselves after an interval of time.
* sine is always odd.
* cosine is always even!!! [i thought it other way round]

so all this info might not be useful for me in practice because of the subject that i teach [information and communication technology] and the level i teach [4 and 5!] but i felt good after taking these notes. i felt back in my element! :) and in the end it wasn't as bad as i imagined it would be :)
