N: I think she make woman feel proud of her,she won the nobel prize twice~ and she doesn't feel very arrogant,she even gave the honor medal for her daughter as toys...now people will know,women also can be a great scientist and dedicate a lot for people~
W: i agree, we shouldn't have sexual discrimination. there are many things girls can do better then boys.
N: so..what else did franklin do for people?he seems knows a lot,he must do lots of things for the world
W: besides electricity, he also have contribution to botany, mathematics, chemistry too. Do you know who invent lightning rod?
N:NO
W: yeah , that was one of franklin's invent. do you know what is Franklin stove?
N: no,what's that??
W: this kind of stove improves the efficiency that the stove burns, saves a large number of faggots, bring very great facility for people of North America area.
N: that's awesome~he invent lots of stuff

N: what is odometer??
W: odometer is something we use on the car, it can accumulate how far we drive one place to another place
N: wow~ it's a really useful invention!! does franklin give u any inspiration?do u want to be a inventor like him?
W: i don't want to be a inventor but i like his attitude for learning , does Mrs. Curie give you any inspiration?
N: yes,i read books about her many times,i also admire her attitude,she is so hard working,and kind for poor student...she has a warm heart,but...it's a shame that i hate science...so im not going to be a scientist like her
W: what did she do for poor student , teach them? or help them to have a good enviroment to study?
N: cos there are lots of people who doesnt have money to go to school,so she spent money to buy table,chair and books for the children,teach them for ftee she is the glory of women,i wish i could do someting for poor people
W: wow that's great, after all , at this time , there are many people need others help.
N: yes,i agree,i can't do any research...at least i can do something else to help people
W: ok. do you know how Mrs. Curie find radium?
N: they did lots of research to look for new elment...they found it in asphalt after they found polonium (Po) ..they found another radioactive element,it's much stronger,they did lots of research on mineral,and analyze them again and again..finally ,they found radium
After discovery po and radium, they have faced the major problem, how is to refine the pure radium and pure po, proved that knows these two kind of new elements to the common people the existence? They must have the large amount fund purchase massive pitchblende and many other minerals and the appliance, can refine the radium and po. They ask the human in various countries to help
finally obtains the Austrian Government and the Vienna academy of science's assistance, by bought inexpensive had been considered at that time that will refine the uranium later not to have the useful pitchblende residual, in 1898 to 1902 these four years, Maria was not only the scholar, was also the technician she fought bravely with every single kilogram pitchblend
w: there's a saying that mrs,curie has many disease when she was young , did it have relation to her research?
N:of course,she stays in her laboratory all day,and she has to touch the radioactive elements for long time,it did hurt her health a lot (she research the element without any protection)
W: so, she sacrifice her health to do the research. she is really a great women int the world.
N: yes,totally agree!!
W: so franklin and mrs. curie are two important people to find or invent something to let our live more convenience, we should proud of them. hows your weekend?
N: i went to my nephew's birthday party,had lots of fun with my cousins,and u?
w: i have a activity this weekend and i need to prepare a perform whith my friend , see you.
