Those numbers, which included the relative distances of the repetitive elements in the DNA molecule, and the dimensions of what is called the monoclinic unit cell — which indicated that the molecule was in two matching parts, running in opposite directions — were decisive. The report was not confidential, and there is no question that the Cambridge duo acquired the data dishonestly. Their behaviour was cavalier, to say the least, but there is no evidence that it was driven by sexist disdain: Perutz, Bragg, Watson and Crick would have undoubtedly behaved the same way had the data been produced by Maurice Wilkins.Francis Crick, James D. Watson, Rosalind Franklin, Maurice Wilkins, Fred Hoyle
Had Watson bothered to take notes during her talk, instead of idly musing about her dress sense and her looks, he would have provided Crick with the vital numerical evidence 15 months before the breakthrough finally came. This meant that DNA was in two parts or chains, each matching the other.
While Watson and Crick were working feverishly in Cambridge, fearful that Pauling might scoop them, Franklin was finishing up her work on DNA before leaving the lab. The progress she made on her own, increasingly isolated and without the benefit of anyone to exchange ideas with, was simply remarkable.
To prove her point, she would have to convert this insight into a precise, mathematically and chemically rigorous model. She did not get the chance to do this, because Watson and Crick had already crossed the finishing line — the Cambridge duo had rapidly interpreted the double helix structure in terms of precise spatial relationships and chemical bonds, through the construction of a physical model.
In the middle of MarchWilkins and Franklin were invited to Cambridge to see the model, and they immediately agreed it must be right.

It was agreed that the model would be published solely as the work of Watson and Crick, while the supporting data would be published by Wilkins and Franklin — separately, of course.
As a result of a deal struck by the two laboratory directors, articles by Wilkins and Franklin, which included their X-ray diffraction data, were modified and then published second and third in the same issue of Nature, seemingly only in support of the Crick and Watson theoretical paper which proposed a model for the B form of DNA.

She is reported to have commented, "It's very pretty, but how are they going to prove it? As such, her response to the Watson-Crick model was in keeping with her cautious approach to science. At first mainly geneticists embraced the model because of its obvious genetic implications.

Her new laboratories were housed in 21 Torrington Square, one of a pair of dilapidated and cramped Georgian houses containing several different departments; Franklin frequently took Bernal to task over the careless attitudes of some of the other laboratory staff, notably after workers in the pharmacy department flooded her first-floor laboratory with water on one occasion.
Despite the ARC funding, Franklin wrote to Bernal that the existing facilities remained highly unsuited for conducting research " Her meeting with Aaron Klug in early led to a longstanding and successful collaboration. They soon discovered published in that the covering of TMV was protein molecules arranged in helices. In he and Franklin published individual but complementary papers in the 10 March issue of Nature, in which they showed that the RNA in TMV is wound along the inner surface of the hollow virus.
The previous year, Franklin had visited the University of California, Berkeleywhere colleagues had suggested her group research the polio virus. Eventually, Bernal arranged for the virus to be safely stored at the London School of Hygiene and Tropical Medicine during the group's research. With her group, Franklin then commenced deciphering the structure of the polio virus while it was in a crystalline state. She attempted to mount the virus crystals in capillary tubes for X-ray studies, but was forced to end her work due to her rapidly failing health.
Her materials included table tennis balls and plastic bicycle handlebar grips. They eventually succeeded in obtaining extremely detailed X-ray images of the virus. In JuneKlug and Finch published the group's findings, revealing the polio virus to have icosahedral symmetry, and in the same paper suggested the possibility for all spherical viruses to possess the same symmetry, as it permitted the greatest possible number 60 of identical structural units.
She developed her scepticism as a young child. Her mother recalled that she refused to believe in the existence of godand remarked, "Well, anyhow, how do you know He isn't She?
Science, for me, gives a partial explanation of life I do not accept your definition of faith i. Your faith rests on the future of yourself and others as individuals, mine in the future and fate of our successors. It seems to me that yours is the more selfish A creator of what?
I see no reason to believe that a creator of protoplasm or primeval matter, if such there be, has any reason to be interested in our insignificant race in a tiny corner of the universe. As the only Jewish student at Lindores School, she had Hebrew lessons on her own while her friends went to church. And on December 21,the Apollo 8 spacecraft launched, becoming the first manned moon mission.
In modern times, we view the phenomenon of the solstice from the position of space, and of the Earth relative to the Sun. Earlier people, however, were thinking about the Sun's trajectory, how long it stayed in the sky and what sort of light it cast.

Some have theorized that the position of the Sun was of religious significance to the people who built Stonehenge, while other theories hold that the monument is constructed along natural features that happen to align with it.
The purpose of Stonehenge is still subject to debate, but its importance on the winter solstice continues into the modern era, as thousands of hippies, pagans, and other types of enthusiasts gather there every year to celebrate the occasion.
A Saturnalia celebration in England in It quickly became a time of widespread revelry and debauchery in which societal roles were overturned, with masters serving their slaves and servants being allowed to insult their masters.
Mask-wearing and play-acting were also part of Saturnalia's reversals, with each household electing a King of Misrule.
Saturnalia was gradually replaced by Christmas throughout the Roman Empire, but many of its customs survive as Christmas traditions. In pre-Islamic times, it heralded the birth of Mithra, the ancient sun god, and his triumph over darkness.
