They described highly sensitive experiments designed to tackle the problem of tumult in fluid flows.
Still more sensitive experiments involving even larger quantities of matter will be needed to test them.
Lead in general use is only slightly radioactive, but for the most sensitive experiments even this small amount must be avoided.
The resistance due to this effect is tiny compared with that of non-superconducting materials, but must be taken into account in sensitive experiments.
A sensitive but passive experiment will study space radiation.
This requires extremely sensitive experiments which search for a deviation from the inverse square law of gravity over a range of distances.
As of 2012 the situation is unclear but future more sensitive experiments are expected to eventually resolve this controversy.
Either way they couldn't be permitted to leave--not after viewing the sensitive experiments in Moset's laboratory.
But again and again in recent years, increasingly sensitive experiments have decisively proved that Einstein's explanation was wrong and quantum theory is correct.
They protect the experiments against environmental influences (that could influence and falsify the most sensitive experiments) like vibrations or electro-magnetic fields.
