The culprit is static electricity. You are insulated by your rubber shoes and she (and metal handles) are providing a route to the ground. Here is more stuff - http://www.electrostatics.net/articl...tic_shocks.htm
Thank you

Ask a Scientist

To prevent the static electricity building up and discharging on your lover's lips, you need to connect the under surface of the shoes to your skin. This is easily done by pushing a thin wire through the sole of each shoe, but the problem might result in uncomfortable shoes! Or you could carry a piece of metal, and touch it regularly on the heating radiators, the water taps, the electric cooker, or other equipment with a metal casing. .

Re: Ask a Scientist

If someone were to leave a 64GB Sandisk microSD card in the inside pocket of a jacket.. what would be the chances that it survives a dry cleaning?

Relatively high, I would have thought. Something above 90%.

Things start to look bleak if you had Fisherman's Friends in the same pocket.

Real numbers are every number that is not complex. So if you don't see something with 'i' in it, it's real.

Rational numbers are anything that can be expressed as a fraction or ratio. The numerator and denominator are integers. If you change the ratio to a decimal, it's either terminating (meaning it stops at some point) or repeating (meaning the same set of numbers repeats).

It becomes irrational if you cannot find a repeating pattern or it doesn't end. For example π is an irrational number.

That's an excellent little excursion to math world, thanks! You should teach math.

Obviously... they go on and on forever.

Ok, the non repeating part is a bit of an issue, but still.

Thank you for your kind words Although, I do prefer to teach physics which has more applied math.

Really,
Physics falls between two stools firstly Newtons laws for large objects which are relatively rational and OK for most cases and on the other hand Einstein's theories which although 100% provable can quickly send you into a mental clinic if you consider all the implications?

I know, I am not saying that it is simple. I also do not understand why I always had better grades in math than physics. I had a fabulous, charismatic, super smart Bohemian WonderWoman for both math and physics. Big greetings to Květuše Řádková!

Nada. Květuše.

Physics, to be honest. I imagined it as movies. Applied anything always made more sense to me in the domain of abstract theories. Except humanities, there it is the opposite. I figure out my own principles. Or refine existing ones. But cramming applied principles in humanities bores me.

I was crap at chemistry all the way until 2nd year Uni when I changed to pure math. Chemistry is to this day one of the most useful things that I was apparently unable to learn.

You know, you should have experimented as a little boy, it would light that special, smelly chemistry fire. My little brother did (if puking out gummybears he soaked in water over night at 5yr of age, actually counts for experimenting) and became a chemistry scientist.

I think there is still hope. You can still light that fire.

Perhaps I didn't make myself clear.

Although I didn't get good marks in chemistry, and certainly never felt that it came easily to me, it is something that I routinely use in every day life when I am trying to understand or achieve something, be that why a Souffle doesn't rise at all, or a Pancake too much (or how to electro plate something, or why some glue won't bond).

I can't remember ever having solved a practical problem by remembering "Battle of Hastings, 1066", but I regularly think "Is that an ionic solution, is that a redox reaction?" and go grab my CRC manual.
