1. Introducing a new reference system is by no means advantageous for adapting from an old system to a new one would entail a great deal of experimental errors.

2. Assuming the existence of perturbations in waves in this case the question arises as to what extent such perturbations are modified when transmitted through a magnetohydrodynamic shock.

3. I suggest you should encourage all their endeavours to find ways of eliminating errors in estimating the quantity of radiation reaching the screen.

4. The two cameras are designed to be sufficiently similar in function to ensure that an operable camera of some kind will be among the initial (исходных ) instruments even if one camera were to fall in orbit.

5. The possibility of explaining anisotropy on the basis of ordinary scattering theory does not appear to be excluded.

6. The particles will in fact execute small oscillations about the stable orbit and will continue circulating indefinitely without gaining or losing energy.

7. Should the material be durable and meet all other conditions no doubt it would be employed fairly often.

8. If subjected to a magnetic field the particle experiences acceleration.

9. The species to be exposed to light are exceedingly active if employed under the conditions of excessive moisture.

10. In addition to showing the changes of fluid configuration, the particles enable the surface position to be followed.

11. The delay is presumably due to the necessity for the energy to be distributed in such a way as to form an activated complex appropriate to the reaction.

12. Only Titan is large enough for its gravitational self-compression to affect its density appreciably when this self-compression is taken into account, the density estimate for Titan (1,9 grams per cubic centimeter) becomes compatible with mixture of half rock and half ice.

1. The centrifuge requires only 100 kilowatt-hours per separative work unit. This power is expended in overcoming the friction of rotating parts as well as electrical losses due to heating of the motor.

2. Although commuting experience proved very encouraging we have thus far failed to present any explicit analysis of it.

3. The element being investigated differs from the corresponding one by decaying when exposed to an acid.

4. Originally the parity of a number was its property of being either odd or even. Later this concept was extended to apply not just to numbers but to mathematical functions as well.

5. Young followed by Fresnel revealed that under certain conditions light did exhibit phenomena of interference.

6. This is an exceedingly small linear dimension for a star, indeed, it is very close to the diameter the sun would have if it were compressed to such a high density that it formed a black hole.

7. Instead of observing the crystal while it is growing a different approach is to watch the crystal surface on which growth has been checked.

8. Attached to the side of the camera is a four-inch visual objective for guiding, its focal length being closely the same as that of the photographic objective.

9. To examine whether or not it is feasible for the reaction products to fit those anticipated by the theory turned out to be a problem of significance.

10. The fraction of primary cosmic rays with energies greater than 10 electron volts is so small that in order to capture one particle per hour one would need a collecting device at least 10 meters on a side.

11. The earlier measurements were confined largely to scattering in the forward direction on account of the scientists encountering formidable experimental difficulties in measuring the cross-section at large angles.

12. Frequently encountered in practice are denser plasmas whose Hall parameters, the ratio of cyclotron frequency to collision frequency, are large for electrons but small for ions.
