Answer: Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that:
- you can exactly measure the strength of the radiation from uranium;
- the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is;
- the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself - a revolutionary discovery!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the "detective work" with his wife. And Marie was proven right
Gerrymandering is a method by which the boundaries of council wards are moved to create the majority desired by the current authority. It was used widely in Northern Ireland by the loyalist authority during the 1920s-30s in order to keep the nationalists (who were generally Catholics) subdued, hence stopping them from gaining a political foothold which could have led to the destabalisation of the Northern Irish state.
I am not aware of it being expressly illegal (I study History GCSE, not government and politics), but I imagine such an action would be taken to make elections more fair, gaining equal representation of each sect within the population to allow equal civil rights for all. It would also make elections more competitive, preventing one political party from abusing their power to remain dominant in a country, despite public opinion as a whole.
It makes elections unfair because if there is a slight majority of supporters of party A in one part of a city (for example), the boundary of the electoral wards could be moved to subdivide it into minorities compared with supporters of party B in other areas of the city, whereas a whole this area would have easily voted-in a party-A representative.
I hope this helps, although it is quite a tricky concept to explain in detail.
Answer:
Renaissance was primarily influenced by secular ideas, but what is interesting is that inside the Renaissance there was also a tide of thinkers and artists who were predominantly using Bible as their primary source.
Explanation:
As in the Renaissance the man is put in the center of everything, and individuality is pretty important characteristic of this period, it opposed the usual ways of thinking, according to which God and Church are dominating the everyday's life. Renaissance artist saw the ideals in Antiquity, not in Christian church. Still, many of them, such as Michelangelo closely collaborated with the church.

I think racial profiling is always negative. If you judge someone based on their race or think that someone is more prone to violence because of their race, that can cause some serious misunderstandings or harm to that person. I do think that profiling based on someone's demeanor is helpful, though. As well as profiling based on obvious things like if they appear overly cautious or nervous.
