Welcome to a new feature on my blog ... WILT .

This is a FLA ( four letter abbreviation ) for the phrase ... What I've Learnt Today

WILT for Thursday 15th November

If I lived on the moon I would weigh about 1/6 of what I weigh on earth ... in Newtons or something. Therefore I am moving to the moon. Unfortunately my mass according to my son's GCSE revision book would remain the same. My mass is the 'stuff' I'm made of , in my case fat , lard , marshmallow and the 4 mini mince pies I had for lunch. This is not a compelling enough argument to persuade me to move to the moon although it would enforce a rather strict diet regime as there would be no Dominos Pizza delivery service or fish and chip shops. Presumably I would have to eat moon dust and leftover NASA space probes.

I am 'helping' youngest son to revise Physics. I could re-write that last sentence as shouting at youngest son for making me speed read the CGP revision book for Physics GCSE because he should know this by now hence the word 'revision'.

I am running on empty after an exhausting week of helping other people's children ( other than my own ) to pass their exams. The next formula I must learn is Work Done ( Joules ) = Force x Distance. I will be calculating this as the work done in lifting a large glass of red wine from the table to my mouth , a distance of some 20cms. I Have no idea how many Joules this might involve and nor do I care at this stage.

Anyone else surviving exam week ?
