What are the two main divisions of science?
According to Ernest Rutherford, physics and stamp collecting, though that's a bit pejorative. One common division is between physical sciences (physics, chemistry, geology, astronomy) and life sciences (biology, medicine, pharmacology).
Ernest Rutherford Did he become famous straightaway?
Ernest Rutherford discovered that atoms have a very dense nucleus, which contains protons.Rutherford eventually coined the terms for some of the most basic principles in the field: alpha, beta, and gamma rays, the proton, the neutron, half-life, and daughter atomshe found that all known radioactive elements emit two kinds of radiation: positively and negatively charged, or alpha and beta. He showed that every radioactive element decreases in radioactivity over a unique and regular time, or half-life, ultimately becoming stable.He discovered the atomic nucleus and developed a http://wiki.answers.com/dp13at.htmlelof the atom that was similar to the solar system.Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding. As part of an experiment with x-rays in 1909, Rutherford was shooting a beam of alpha particles (or alpha rays, emitted by the radioactive element radium) at a sheet of gold foil only 1/3000 of an inch thick, and tracing the particles' paths. Most of the particles went right through the foil, which would be expected if the atoms in the gold were like a plum pudding. But every now and then, a particle bounced back as though it had hit something solid. After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than the atom itself. All of the negative charge was held in the electrons, which must orbit the dense nucleus like planets around the sun.He was the New Zealand physicist who split the atomFrom: Bradwell Institute Information
How did Rutherford make out that 1 in 20000 alpha particles retraced its path?
Actually, it was two students of Rutherford who made this discovery. Ernest Marsden, and Hans Geiger, both of whom went on to better things later in life. For their experiments, they had to sit in a darkened room till their eyes had adjusted to the darkness, and the they fired their particles at a gold foil, their target. The diffraction was recorded on the far side when the particles hit a ZnS screen, which fluoresced briefly. It was their idea to erect the detector screen towards the near side of the target, and observed the reflected particles. It was a few weeks before Rutherford actually saw their results, and was amazed by what he saw. As to the numbers, that merely came out of the mass of data.
What was Ernest Rutherford's family life?
Ernest Rutherford had 7 brothers,Percy(died as an infant),Herbert and Charles(downed in perlorus sound when sailing),George,James,Arthur and Ernest himself grew till manhood. Ernest Rutherford also had 5 sisters,Nellie(Mrs M.P.Chapman),Alice(Mrs A.T.Elliot),Florence(Mrs H.G.Streiff),Ethel(Mrs H.G.Sergel) and Eva(Mrs .LT.Bell) Ernest Rutherford's father James was a scottish wheelwrite and his mother n'ee Martha Thompson was an English school teacher.

Who discovered radioactive decay in 1898?
ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.

What were some Fred hollows important events in his life?
One of the important events of Fred's life was him winning the Australian of the year award in 1990.
What does it mean to have a half life?
A half life means the time required for something to fall to half its initial value. The original term was used by Ernest Rutherford's discovery of the principle in 1907 as "half life period," but was shortened to "half life," in the 1950's.

What was Rutherford's thinking style?
Ernest Rutherford (August 1871 to October 1937) is known as the father of nuclear physics. Some of his discoveries include the concept of radioactive half-life, radioactivity involved the transmutation of one chemical to another and he differentiated and named alpha and beta radiations.
