Galilei and Gutenberg -by Yealin and Sally === S:Sally Y: Yealin One day, Yealin and Sally. They talked to each other in facebook. They talked about two famous people. This conversation about what they talked.=== ===S:Hi,Yealin. How are you? Y:I am fine Sally! Today, let's research about Galilei and Gutenberg! S:Do you know who is Galilei and Gutenberg? Y:Johannes Gutenberg is the man who was the first European printer, and inventor of movable type and Galilo Galilei is the Italian scientist of the late sixteenth and seventeenth centuries. S:Ok. Let's talk about Galilei and Gutenberg. Y:sure! S:Do you know what their jobs are? Y: Gutenburg was the printer. he developed the technique or text-creation and typographic printing. also he was inventor too, and Galilei was the scientist and he is the first person who used a telescope. S: Yes. Do you know Where are they live? Y: Gutenberg.. he was the European printer, so it is going to be he lived in Europe, right? And Galilei.. lived in Italy, wasn't he? S:Uh-uh. What are they invented? Y: first, Gutenberg invented the technique of text-creation and typographic printing. At first, all Greece and Roman are wrote by handwriting, but after he made the printer, all people did not have to copy the book by hand. Galilei invented the telescope that examine objects in the sky, or see the moon. also he wrote the book and he showed great ability at the math. S:Great! The Galileo Galilei invented the telescope,but do you know when he used a telescope, what he saw in the space? Y: he saw the moon of Jupiter, the mountains on the moon, and sunspots. I think he really liked watching the space and planets. S: I think you know Galilei against the cosmology. Which cosmology he against? Y: he argued for the Copernican theory and against the traditional geocentric cosmology. S:How about Gutenberg? how his invention improved people's life? Y:If he did not developed the printing until this time, we may copy somethings in our handwriting. I don't want to imagine that, that might be horrible. S:Haha! That is right! Then what is a biggest different between handwriting and printing? Y: handwriting is, like the name, we need to write in our own hands, so it spends lots of time and our hands will be so hurt, but printing is just print itself, so we don't have to move our hands, just click the button. S:Do you think those two things(inventions) are important to your life? Why? Y:Of course it is! Because of those two people, we don't have to copy something by our hands, and we can see the moon and other planet and that's why we found like Mars, Venus, and how they formed! I think they are genius! Don't they??? S:Yes, I agree with you. I think those two inventions are very important to my life. Especially the printer. I always print some homework,because printing is quickly than writing in the paper, and the homework will be cleaner than writing. Y:I think so too! They are very useful. S: I am very happy to talk with you! I got many information to you! Thank you so much! Have a nice day! Y:You too! ===
