Ether winds

The significance of the Michelson-Morley experiment was not assimilated by the scientific community until after Einstein presented his theory. In fact, when Michelson was awarded the Nobel prize in physics in 1907, the first American to receive that honor, it was for his measurements of the standard meter using his interferometer. The ether wind experiment was not mentioned... 

It was ultimately recognized, as Poincare pointed out, that a complete conspiracy is itself a law of nature, that it is not possible to discover an ether wind by any experiment that is, there is no way to determine an absolute velocity.

If you know you have low-boiling material in your compound, think about distilling it at atmospheric pressure first. If, say, half the liquid you want to vacuum distill is ethyl ether from an extraction, consider doing a simple distillation to get rid of the ether. Then the ether (or any other low-boiling compound) won t be around to cause trouble during the vacuum distillation. If you distill first at 1 atm, let the flask cool BEFORE you apply the vacuum. Otherwise your compound will fly all over and probably will wind up, undistilled and impure, in your receiving flask.

Crude experiments were performed in the laboratory with substances unlikely to show significant weight change by adsorption of water or oxygen and sufficiently volatile for loss to be recorded conveniently on an ordinary balance. Petri dishes (41 sq. cm. area) were used to contain the substances, mostly liquids and used in the pure state. Two solids were included p-dichlorobenzene and naphthalene. These were layered in coarse powder form, and the surface was sprayed with a solution of low molecular weight polyisobutene in petroleum ether until it was sticky enough to prevent blowing of the powder in the wind it was intended to use. 

This is a useful way to make amino ethers with a meta relationship as both groups are ortho, para-directing and so the meta compounds cannot be made by electrophilic substitution. The alternative is the long-winded approach using a diazonium salt that was described in the previous section. 

Template monomer 7 (0.75 g), AIBN initiator (120 mg), crosslinker ethylene dimethacrylate (15.0 g) in tetrahydrofuran (15.0 g) were filled into a tube, carefully degassed by three freeze-thaw cycles, sealed under argon, and polymerized for four days at 65 °C. The tube was then cooled and broken, and the polymer was milled with an Alpine Con-traplex 63 C, and sieved to a grain size of 125-163 pm. Alternatively, the polymer could be milled to a finer powder and separated to a particle diameter fraction of 8 -15 pm by a wind-sieving machine (Alpine Multiplex 100 MRZ). This material was first extracted with dry diethyl ether before being dried in vacuum at 40 °C. The template was removed from the polymer by a continuous extraction with methanol-water (250 mL per g of polymer). After the solvent was evaporated, the residue was dissolved in a defined volume of methanol and the content of 7a was determined polarimetrically. 

The notion of the four elements held sway over the minds of men for two thousand years. Though now dead, as far as science is concerned, it still lives on in our common phrases. We speak of the raging of the elements, for instance, when we wish to say that wind (air) and waves (water) are driven to fury by a storm. As for the fifth element (ether), the phrase becomes quinta essentia in Latin, and we still mark its Aristotelian perfection when we speak of the quintessence of anything, meaning that thing in its purest and most concentrated form.
