The Internet Oracle has pondered your question deeply.
Your question was:
> O great Oracle who designs all these fantastic
> constants: Please tell me why we have to do pointless
> AND boring experiments in physics to find
> inaccurate versions of constants that we already
> know?
And in response, thus spake the Oracle:
Ohm my god - Avogadro tell you a story Joule really like!
I Nu this fellow Schroedinger who was great at interviewing people - he
was like an emcee, squared. Anyway, Theta-ther day Schroedinger offered
to sell me his cat (I guess he didn't Quantum). So, um, the Moment,um,
I first see this cat he Volts! And now every time I come home he
Boltz,mann! He gets Tensor and Tensor.. like his former owner was
torturing him on Dirac!
I wanted to Force Schroedinger to explain, but the Current issue was my
cat's Resistance to be around me. Then one day after Mass, I turned on
the Vacuum, and the Volume surprised him so much that when I turned it
off, he acted as gentle as a Lambdoes. So now I take him to the
Circuits seven times a week - that's a Faraday!
Anyway, I went to c Schroedinger. "Did you Hertz that cat? Phi on you!"
I said.
But he exploded: "Watt!??! Such Impedance! That Torr it - you used to
have Potential, but if you don't speak with Gravity, the end of your
career is Lumen!"
Well, it was all I could do to Coulomb down, but I don't want to Bohr
you with the details. Planck's for a great question!
You owe the Orace a joke that ends: "Vector? I barely know her!"
