If you have millions of samples to do then yea, that much effort each will take forever. But those kind of techniques are good if you're making up a stock solution. You can then make the stock very precise and distributing it into portions can be done quickly and easily with lower grade gear; faster than weighing each. Also, remove the cap or stopper from any container and replace it with test tube sealing plastic. I don't mean food wrap (static)
Once the weight paper is on the balance with chemicals on it, it stays on the balance until you get the 4 digits you are looking for. The chemical balance is done on top with a spatula. If you get the exact reading you close doors and see if it's really the reading you want.
I know why they tell you to add/remove chems outside the balance...the faculty doesn't wana pay extra maintenance costs to clean them...you will be much more precise if you let the damn thing in there ^_^
Nice guide but unrealistic. Nobody in his right mind would go through all those steps when you have 100 measurements waiting for you, and also considering you have to go home to eat or spend time with your kids ^_^
just do key bumps till you get where you wanna be. no need for a balance if you have a decent tolerance

LHCb sees where the antimatters gone
ALICE looks at collisions of lead ions
CMS and ATLAS are two of a kind
Theyre looking for whatever new particles they can find.
The LHC accelerates the protons and the lead
And the things that it discovers will rock you in the head.

LHC people are newbs. They won't give up until they blow up their billion dollars facility. I will laugh at them when it happens.

thanks for putting MIT lectures online for free. I feel smarter already.
