Somehow I thought wheels are way more simple than complicated city constructions and delicate instruments.]]> 2022-06-13 03:11:42 UTC https://padlet.com/2tclub/newtome106/wish/2219002750 https://padlet.com/2tclub/newtome106/wish/2219003324 I thought bamboo filament light bulb is intersting.

Kinda ironically, it's quite funny they took so long to come up with a nail-making machine after the industrial revolution.]]> 2022-06-13 03:12:36 UTC https://padlet.com/2tclub/newtome106/wish/2219003566 https://padlet.com/2tclub/newtome106/wish/2219004326  I didn't knew that the first wheel was developed in 4000 B.C.. I thought wheel might developed more earlier.
 How could people live without wheels by that time?! How did they move heavy rocks or blocks to make huge structures? After reading this paragraph, I became curious about their lifestyle without wheels.]]> 2022-06-13 03:13:26 UTC https://padlet.com/2tclub/newtome106/wish/2219004326 https://padlet.com/2tclub/newtome106/wish/2219004386 The fact that this Joseph Wilson Swan first invented modern, longer lasting light bulbs was really new to me. So Thomas Edison only became popular for making light bulb manufacturing easier?]]> 2022-06-13 03:13:29 UTC https://padlet.com/2tclub/newtome106/wish/2219004386 https://padlet.com/2tclub/newtome106/wish/2219005211  I was surprised that until the 1790s and early 1800s, hand-wrought nails were the norm. In fact, I didn't thought deeply about making nails because nails are usually used in making and building something else. Those are materials!
 By reading this paragraph, I learned about how the nails were made, and got a chance to realize materials that we usually use also have to be made by someone.]]> 2022-06-13 03:14:26 UTC https://padlet.com/2tclub/newtome106/wish/2219005211 https://padlet.com/2tclub/newtome106/wish/2219005481 I thought the axle is important role in the car.

But, I learned that in 1850 an English physicist named Joseph Wilson Swan created a “light bulb” by enclosing carbonized paper filaments in an evacuated glass bulb.
 After I read this paragraph, I wanted to know more about inventions that I knew incorrectly. So I searched more about world's invention, and I was surprised that airplane was first invented by 릴리엔탈(Otto Lilienthal).]]> 2022-06-13 03:15:05 UTC https://padlet.com/2tclub/newtome106/wish/2219005734 https://padlet.com/2tclub/newtome106/wish/2219007077 I was surprised about the origin of wheel.

Scientists such as Humphry Davy and Joseph Wilson backed up the fundamental development of electric lights. I was curious why Thomas Edison is the most famous person who pioneered the electric modern life.]]> 2022-06-13 03:20:01 UTC https://padlet.com/2tclub/newtome106/wish/2219009796 https://padlet.com/2tclub/newtome106/wish/2219010129 I knew that it was a 'rolling rock' which was a first found of wheel. But it has to have fixed axile, so it was a 'true potter's wheel' which is a true found of wheel.

The soft steel wire is easy to change the form but the fact nail was made that the soft steel wire is interesting.]]> 2022-06-13 03:20:54 UTC https://padlet.com/2tclub/newtome106/wish/2219010496 gkdudjeong https://padlet.com/2tclub/newtome106/wish/2219011043 I didn't know that the wheel is that old.

Until the 1790s Until the 1790s and early 1800s, hand-wrought nails were the norm, Nail-making machines came online between the 1790s and the early 1800s. And by 1886, 10 percent of U.S. nails were created from soft steel wire. By 1913, 90 percent of nails produced in the U.S. were steel wire.

But from this writing, I knew that it was a physicist named Joseph Wilson Swan, who had created a “light bulb”. However, in the proccess, it had trail and error. But Swan was able to develop a longer-lasting lightbulb. And Thomas Edison was a person who improved on Swan's design.

Edison eventually discovered that a carbonized bamboo filament could last over 1200 hours. But, it was not the Edison who invented the whole light bulb.

Thus, I think all three inventions are important. But, If I choose one of the three, I think it's a light bulb. Because the bright light of the light bulb brightens our lives even if it is not at night.]]> 2022-06-13 03:25:58 UTC https://padlet.com/2tclub/newtome106/wish/2219014751 https://padlet.com/2tclub/newtome106/wish/2219014862 The light bulb wasn't invented by Edison.
