(S.I.) Platinum Bar is getting heavier

http://www.abc.net.au/worldtoday/content/2012/s3435774.htm

 

The amount of platinum/iridium that gets cleaned off is atoms thick, nano-meters tops. And the amount that gets deposited onto the "lump" from car exhausts again is miniscule if any at all, did you know they keep it under an inert gas, either nitrogen or argon or something like that also this pic is pretty cool, like a russian doll http://physics.nist.gov/cuu/Units/kilogram2.html

 

Don't forget that there is also a 0.5% variance in the weights of objects across the globes surface.

my bathroom scales say it's more of a 20% variance :lol:

 

Its my clothes that tell me whats going on they seem to have shrunk

 

Tell me about it... I've got a PVC raincoat that appears to have shrunk... that's the only explanation I can come to

 

Well I just learnt something new. I always thought mass was determined by the weight of water relative to the metre. Ie 1 cubic meter = 1t/ 1 litre = 1kg etc....... That's just coincidence?

 

Not a coincidence, originally it was but then found to be slightly inaccurate. It is very, very slightly different to a kilo (under certain conditions of course - e.g distilled water at maximal density).

 

Except that the S.I. Platinum bar is a standard mass not a standard weight.

 

oh yeah? so what are the units of measure (SI) for mass?

 

Here, Let Me Google That For You.

 

so weight is mass then?

 

Nope. Weight is the force on an object due to gravity and is measured in Newtons. On earth, a mass of 1kg has a weight of about 9.8N (depending where on earth you are) but only 1.6N on the moon.

 

But an object can't be two places at once

 

Quantum physics says it can.

See, ... Iknew I wasn't fat.. it's just gravity's fault

 

Isn't that what I said? The weight reading of the unchanged mass of any singular object varies about 0.5% when its measured at different locations across the globe's surface.

 

yep

 

Got an update on this... ever heard of the Grav?

...and spot the scientist with the Aussie accent

Appears to be very hokey for a number of reasons. First, if that sphere were really a mulimillion dollar object, why would they have it on a flimsy pedestal and allowing some hapless guy who waves his hands continuously inches from this alleged invaluable object? Why would they allow this hapless guy to even pick it up...with only one hand gloved when they keep the much less valuable official kilo under 3 bell jars in an atmosphere controlled room under 3 special locks? Just seems completely hokey.

To make matters worse, why are they grinding this by hand in what appears to be an amateur's grinding tub? Wouldn't the whole process be done by computer controlled grinders in a state-of-the-art facility?

Just way too hokey.
