"Do you know how?" "No, Lieutenant. If we had parts, I could put bombs together. I can take them apart, but I don't know how to make two out of one." The Italian Planeteer looked accusingly at Rip. "I thought maybe you knew, sir." Rip grunted. If they had parts, he could assemble nuclear bombs, too. Part of his physics training had been concerned with fission and its various applications.

In this way, it is conceivable, that animals might arise in the form of long chains of similar segments, each of which chains would consist of a number of imperfectly separated individuals, and be equivalent to a series of separate individuals belonging to kinds in which the fission was complete. In other words, Mr.

Multiplication by spontaneous fission seems from some recent researches to be much less frequent than has been supposed, and more evidence is required as to the fact of the habitual propagation of any planariæ in this fashion.

There are no truly hermaphroditic mammals, i.e., individuals in which both the male and the female germ cells function, except perhaps in rare instances. Sexless or asexual reproduction assumes various forms. What is usually considered the most primitive of these is fission or simple division, in which the cell divides into two equal, identical parts. There is of course no suggestion of sex here.

In short, the bacteria after two centuries of study appear to us about as they did at first. They must still be described as minute spheres, rods, or spirals, with no further discernible structure, sometimes motile and sometimes stationary, sometimes producing spores and sometimes not, and multiplying universally by binary fission.

In all the different forms of asexual reproduction from fission to parthenogenesis, the female may in this sense be said to exist alone and perform all the functions of life including reproduction.

A nuclear bomb was actually pretty complicated. It had to be complicated to keep the pieces of the fissionable material apart until a chemical explosion drove them together fast and hard enough to create a fission explosion. If the pieces weren't brought together rapidly enough, the mass would fission in a slow chain reaction with no explosion. Rip was trained in scientific analysis.

"Mamma dear, will you please tell us the story of 'The Three Bears'?" "No, my love, not to-day, I have told it you very often lately and I am busy." "Very well, Mamma dear, then we will tell you the story of 'The Three Bears." The Iliad and the Odyssey are only "The Three Bears" upon a larger scale. Just as the life of a man is only the fission of two amoebas on a larger scale.

He sliced off the inner side where it tapered to a cone, then, working only by eye estimate, cut out a hole in which the wedge of fission material would fit. He wasn’t off by a thirty-second of an inch. Skillful application of the torch melted the thorium around the wedge and sealed it tightly. Koa was ready with a sheet of nuclite.

In other words, in proportion as the industrial process is enhanced in productivity by the concentration on it of the higher faculties of mankind, there is an increasing fission of this process as a whole into two kinds of activity represented by two different groups.
