Crossword-Solution: ANISOTROPIC 11 letters, 1 clue 🏆 scrabble score: 15

The responsive peculiarities of epidermis, epithelium, and gland; the response of the digestive organ, with its phasic alterations; and the excitatory electrical discharge of an anisotropic plate, are the same in the plant as in the animal.

Bose found 'differential excitability' is widely present as a factor in determining the character of special responses and showed that many anomalous conclusions, with regard to the response of certain animal tissues, had arisen from the failure to take account of the 'differential excitability' of anisotropic organs.

However, the most careful observations have never revealed such anisotropic properties in terrestrial physical space, _i.e._ a physical non-equivalence of different directions.

For motion in three dimensions we have in like manner d[rho] d / d[rho]\ d / d[rho]\ d / d[rho]\ ------ = -- ( K ------ ) + -- ( K ------ ) + -- ( K ------ ); dt dx \ dx / dy \ dy / dz \ dz / and the corresponding equations in electricity and heat for anisotropic substances would be available to account for any parallel phenomena, which may arise, or might be conceived, to exist in connexion with diffusion through a crystalline solid.

Both are adapted for determining the axes of elasticity and for the differentiation of isotropic and anisotropic bodies.
