Page 133 - Two variable organs are said to be co-related when the variation of the one is accompanied on the average by more or less variation of the other, and in the same direction. Thus the length of the arm is said to be co-related with that of the leg, because a person with a long arm has usually a long leg, and conversely.
Page 133 - It is easy to see that co-relation must be the consequence of the variations of the two organs being partly due to common causes. If they were wholly due to common causes, the co-relation would be perfect, as is approximately the case with the symmetrically disposed parts of the body.
Page 55 - ... treatment. But Professor Reynolds has shown that the same conditions of similarity hold good, as to the average effect, even when the motion is of the...
Page 6 - It is impossible as yet to sum np all the considerations which go to justify the assumption of the isothermal-adiabatic arrangement, but it is clear that uniformity of kinetic energy must be principally brought about by a process of diffusion. It is therefore interesting to consider what amount of inequality in the kinetic energy would have to be smoothed away. The arrangement of density in the isothermal-adiabatic sphere being given, it is easy to compute what the kinetic energy would be at...
Page 1 - The brighter lines in spiral nebulae, and in those in which a rotation has been set up, are in all probability due to streams of meteorites with irregular motions out of the main streams, in which the collisions would be almost nil.

Page 133 - Co-relation or correlation of structure " is a phrase much used in biology, and not least in that branch of it which refers to heredity, and the idea is even more frequently present than the phrase ; but I am not aware of any previous attempt to define it clearly, to trace its mode of action in detail, or to show how to measure its degree.
Page 378 - As far as the speaker's observations extend, they appear to be in favour of the opinion that these nebulae are gaseous systems possessing a structure and a purpose in relation to the universe altogether distinct from the great cosmical masses to which the sun and the fixed stars belong.
Page 7 - Hence, nothing short of absolute impact ia to be considered an encounter in the kinetic theory, and what is called the radius of " the sphere of action " is simply the distance between the centres of a pair when they graze, and is therefore the sum of the radii of a pair, or, if of uniform size, the diameter of one of them. The next point to consider is the mass and size which mnst be attributed to the meteorites.
Page 9 - From a consideration of the tables in the paper it appears that, with meteorites of 3^ kilogrammes, the collisions are sufficiently frequent even beyond the orbit of Neptune to allow the kinetic theory to be applicable in the sense explained. But if the meteorites weigh 3^ tonnes, the criterion ceases to be very small at about distance 24 ; and if they weigh 3125 tonnes, it ceases to be very small at about the orbit of Jupiter.
