Why not ?

History of the JFI | James Franck Institute

It might interest you that when we made the experiments that we did not read the literature well enough—and you know how that happens.

On the other hand, one would think that other people would have told us about it.

For instance, we had a colloquium at the time in Berlin at which all the important papers were discussed.

Nobody discussed Bohr’s paper.

Why not ?

The reason is that fifty years ago one was so convinced that nobody would, with the state of knowledge we had at that time, understand spectral line emission, so that if somebody published a paper about it, one assumed “probably it is not right.

So we did not know it. — James Franck

James Franck | American Institute of Physics

James Franck was a German physicist who won the 1925 Nobel Prize for Physics with Gustav Hertz “for their discovery of the laws governing the impact of an electron upon an atom”.

Niels Bohr’s Flight From the Nazis Was a Science Drama

And I would like to say that when we got the Nobel prize together, I was only pleased, because he had contributed so much and he was so much more able with experiments than I am, that we really supplemented each other quite well.

Manne Siegbahn Institute

Manne Siegbahn Biography - Childhood, Life Achievements & Timeline

Manne Siegbahn ( 1886 – 1978 ) was a Swedish physicist, who won the Nobel Prize in Physics in 1924, for his work on X-ray spectroscopy.

Born in late nineteenth century in the southern Sweden, he had his schooling at Stockholm and university education at Lund.

Starting his career as a docent at the age of twenty-five at the University of Lund, he discovered a new group of wavelengths, known as the M series, in X-ray emission spectra, at the age of thirty and became full professor at thirty-four.

Later, he shifted to the University of Uppsala and remained there for next fourteen years. Here, he continued with his work on X-ray spectroscopy and established that X-rays, just as light, were electromagnetic radiation.

It was his work on X-ray spectroscopy, which earned him his Nobel Prize in Physics for year 1924 .

Later, he joined University of Stockholm and in the same year, he was chosen as the first director of the Nobel Institute of Physics, established by the Swedish Royal Academy of Sciences. Here he initiated studies on nuclear physics and turned it into a center of excellence.

Young scientists from all over the world came here to work under his guidance. Today, the institute is known as Manne Siegbahn Institute.

Habit of Attention

Robert Millikan, US physicist - Stock Image - C026/4094 - Science ...

The fact that Science walks forward on two feet, namely theory and experiment,

Sometimes it is one foot that is put forward first, sometimes the other, but continuous progress is only made by the use of both-by theorizing and then testing, or by finding new relations in the process of experimenting and then bringing the theoretical foot up and pushing it on beyond, and so on in unending alterations. – Robert Andrews Millikan

Cultivate the ” Habit of Attention ” and try to gain opportunities to hear wise men and women talk.

Indifference and inattention are the two most dangerous monsters that you ever meet.

Interest and attention will insure to you an education. — Robert Andrews Millikan

Robert Andrews Millikan

The Nobel Prize in Physics 1923 was awarded to Robert Andrews Millikan (1868-1953) “for his work on the elementary charge of electricity and on the photoelectric effect.”
