The wave function III. 144 has a very simple form, and applications to the He-like ions show that one can still expect a surprisingly high accuracy. Let us consider a singlet wave function of the form ...

The data show that, in the case of the He-like ions, a combination of the method using correlation factor and the method with different orbitals for different spins leads to excellent results. 

At the end of the paper, condensed tables of the higher approximations have been carried out with respect to atomic and molecular systems. For atoms, the tables are arranged after the number of electrons involved, which means that, e.g., N = 2 refers to the series of He-like ions H", He, Li+, Be2+, etc. For molecules, there is a table for H2 a table for other simple molecules (LiH, BeH+, H20, NH3, etc.) with all or almost all electrons treated, and finally a special table for the n electron systems in the two latter cases, the references to the best SCF data available are also contained for comparison.

As discussed in the early sections it seems that there are very few effective ways to stabilize the transition state and electrostatic energy appears to be the most effective one. In fact, it is quite likely that any enzymatic reaction which is characterized by a significant rate acceleration (a large AAgf +p) will involve a complimentarity between the electrostatic potential of the enzyme-active site and the change in charges during the reaction (Ref. 10). This point may be examined by the reader in any system he likes to study.

After the Nazi takeover, Haber s second wife Charlotte moved to England where one of her sons, Ludwig Haber, became a prominent historian and wrote about chemical warfare, including his father s role in its development. Clara Haber s son Hermann moved to New York City where in 1946 he, like his mother before him, committed suicide. 

With a reckless flair for drama, Midgley used an elaborate series of laboratory demonstrations to help sell the additive to executives and scientists. Holding a small, open bottle of tetraethyl lead up to the air inlet of a knocking engine, he liked to show how its fumes silenced knock s explosions. Midgley was versatile he could invent, devise a practical manufacturing process, and even sell the invention. 

Although Carothers was considered a brilliant experimentalist, he rarely conducted experiments at Du Pont. His job was to think and write. Ninety-five percent of experiments can be proven with pencil and paper and don t require demonstration, he often said. Carothers spent more hours reading scientific literature in Du Pont s third-floor library than any other Du Pont scientist. He liked to sit at a long table overlooking oak and... 

In dielectric materials (oxides, semiconductors, halides, polymers, and he like), polarizability correlates with hardness. For metals, this is not the case. However, the frequencies of the collective polarizations known as plasmons are related to mechanical hardness. 

There was a second thing he liked about Hitler—he was an auto enthusiast. Every man would have a car, said Hitler, and the production of cars would make many jobs. 

But when the Allied investigators got around to Auschwitz, his colleagues had weakened and now it was fantastic for them to pretend that they scarcely knew him. Schmitz admitted that, after consulting the other directors, he had sent Krauch to work for Goering. Schmitz admitted that for years he and Krauch had put their heads together twice a week in Berlin. Then Krauch s colleagues really "threw him a curve" (he liked these American expressions). Every last one of them blamed Auschwitz on "compulsory quotas imposed by the government." And who shoved these quotas down their throats They did not say "Why, the G.B. Chem office, which was too big for any one man." No, they said "G.B. Chem — he set the quotas."... 

A. In terms of my I.G. relationship. That is quite an interesting question. After I had been in the Four Year Plan for a few months, some people in the Reich were asking me to leave I.G. Farbenindustrie. And they asked Goering to put some pressure on me, and Goering declined to do this. He said, Let this man do what he likes. He is a man of the laboratory, not an administrative man."... 

Strutt was the fourth Baron Rayleigh, son of John William Strutt, the third Baron Rayleigh, with whom Ramsay had collaborated on the discovery of argon. He, like Thomson, ran independent experiments that undermined Ramsay, Collie, and Patterson s results ...

(2003).

This leaves option 3b to be scrutinised closely. When the present writer did this, he realised that his puzzlement had arisen because he like others, had fallen into the trap of which he had frequently warned his students and which he has emphasised in his writings it is a serious error to attempt to understand electrochemical phenomena by thinking of ions in isolation, because this puts them putatively into a vacuum. But the ions of concern to us do not exist in a vacuum. Ions would not leave their positions of low energy in a crystal lattice to go into solution or be formed from neutral molecules by the transfer of a charged fragment from one molecule to another if those processes were not made exo-energetic by the interaction of the ions with polar or polarisable species in their environment, most commonly the solvent. For that reason, one should always think, and indeed talk, about... 

If we can do that, why cannot we do that just here and now, without getting out The theory is perfectly correct. If it is possible that we live after death, and make other bodies, why is it impossible that we should have the power of making bodies here, without entirely dissolving this body, simply changing it continually They also thought that in Mercury and Sulphur was hidden the most wonderful power, and that by certain preparations of these a man could keep his body as long as he like.1... 

While Lavoisier s role in the establishment of a physics section is significant, it is made even more intriguing by Arthur Donovan s discovery that Lavoisier actually drew up a proposal for a physics section and a list of nominees in 1766, two years before he was elected to the Academy. Donovan notes that Lavoisier s list of eight nominees included six men whom he likely perceived to be his rivals in upcoming elections to the chemistry section. Was Lavoisier simply devising a method to ensure his own imminent membership in the Academy 32... 

The bottom line as serious as the former employee s intrusions were they pale in comparison with what he could have done to the fresh water system—he could have done anything he liked. (Gellman 2002)...
