because they look tight
why is the northwest passage have been an important discovery
Rutherford discovered Nucleus inside the atom. This will opened the door for better understanding the structure of atom. Radio activity and Nuclear physics developed after discovery of nucleus . Now entire high energy physics developed on the basis of nucleus.
From the discovery of penicillin to the artificial sweetener in our drinks, accidental discoveries have had major impacts on our lives. T. C. Hsu's accidental discovery that mitotic cells washed with hypotonic solution can be easily squashed to visualize the chromosomes is now an important scientific technique for cytological studies. Throughout history there have been many cases of scientists who have set out to investigate one thing but instead make incredible "accidental" discoveries of another. Two examples are the discovery of penicillin, the first antibiotic, and the discovery of saccharin, an artificial sweetener. Even though it might have been luck that had brought the scientists to see an observation, it was genius that made them realize that it was a discovery.
Because no scientific work is considered a "discovery" until it has been independently verified by several other scientists in different places. If their work verifies the original claim, then it is indeed, a "discovery" by the first scientist in question. If the work of the other scientists cannot verify it, or vary wildly from the first scientist's work, then it is not a new "discovery".
The discovery of iron dates back to ancient times, so there is no specific scientist associated with its discovery. Iron has been used by humans for thousands of years due to its abundance and utility.
Microscopes have been crucial in allowing scientists to observe and study cells at a microscopic level, leading to the discovery of their structures, functions, and interactions. This has been fundamental in advancing our understanding of cell biology, genetics, and the development of various medical treatments and technologies related to cells.
That is correct.
because it has been used to find cures for people who are ill
Watson and Crick did with the discovery of the strucure of the DNA molecule in 1953 but the first GMO had been made in the 70's in California, by Americans scientists. =)
The discovery of the fission reaction proved that the atom is not indestructible. Fission is a process by which an atom is split to to produce two atoms, smaller in size than the original atom. In addition the mass of the system after a standard fission reaction is less than the mass of the system before the reaction, some of the mass having been converted to energy. This indicated that it is possible to completely "destroy" an atom (although it is merely converted to a different form). Fission was first observed in 1938 by Otto Hahn who observed that after bombarding a uranium nucleus with neutrons, the much lighter barium was produced.
There are traces of rivers but there has not been an actual discovery of water on Mars. Scientists think the water may be frozen underneath the polar caps.
In outer space, there has been no definit proof that life exists, but there is proof that there was once water on mars, creating the possibility of life. In extreme heat or cold, there have been bacteria that have been found.
