Greatest Inventions Of The 20Th Century

Telephone was invented in the 1876 by alexander graham bell

In 1902 Willis Carrier invented the first modern air Conditioner. Having spent time in China, a country who doesn't use AC anywhere but westernized hotels. I am very thankful I live in a time and place where that is a common luxury.

 

Ha ha...history not my forte...that is why i don't do well with these type of threads unless I do the research first, and i didn't....and I felt well, maybe the telephone was around in the 1800's, as AB was....Did i use my logic...no..... .....Thanks for the correction.

 

M-1911.45acp. John browning inventor. Has served this country and citizens, both good and bad, but hands down the best and still produced item one can buy and not loose money!

 

the rim fire bullet.. & the automatic pistol..

 

I guess Im a weirdo cause I posted my thought without even looking and its almost the same as yogi...

 

They are tools that changed the world as we know it!

 

8-track and Beta max 1970's

Radio but it is 6 yrs to early but I install my grade curve and call it 20th century anyway cause that is when it was used

 

"Q:
Who invented the first spaceship?

A:
No one person invented the first spacecraft, but rather it was the work of a very large team. The first ship to safely put a man in space and orbit the earth was Vostok 1, piloted by Yuri Gagarin in 1961. Sergei Korolëv was the lead designer of the Soviet space program at the time, but many other people were involved in the process.




Q: Who built the first space station?

by Jonathan O'Callaghan, 17 November 2012

A.They might have lost the race to the Moon, but the Soviets beat NASA to the punch when it came to space stations…








The first-ever manned outpost to orbit the Earth was Salyut 1, launched by the Soviet Union on 19 April 1971. The station was small compared to the modern-day ISS, measuring just 20 metres (65 feet) in length and four metres (13 feet) wide. In its 175 days in space, of which only 24 saw the station manned, Salyut 1 completed 2,929 orbits of Earth and travelled a total distance of over 118 million kilometres (73 million miles) before re-entering and burning up in the Earth’s atmosphere. Only one crew ever successfully docked and visit the station, the three-man crew of Soyuz 11, although they sadly lost their lives on their return to Earth and became the only ever astronauts to lose their lives in space.

Salyut 1 was succeeded by eight more Soviet-built space stations, culminating in the construction of the giant Mir space station that began in 1986, with NASA’s Skylab station sandwiched in-between in 1973. Mir retained the record for the longest orbiting man-made space station until being surpassed by the ISS in 2010."


so i conclude that the first success into space was in the 20th century.

 

but was that change for the better...........

 

That all depends. If you were getting robbed, a .45acp to their face would be a good thing!

Confiscated firearms that end up back on the street in the hands of kids, bad!

Then again, my baseball bat will do some serious damage too, so will a pizza pan! Anything can be used to kill, I still view the 1911 .45acp as one of the most versatile tools one could ever have.

 

but that is a very myopic viewpoint. I am talking overall globally in the final analysis.

Like I said concerning the internal combustion engine. sure the tech is great and all, but in an overall appraisal, the internal combustion engine and everything attached to it's use has done far more damage globally than it has cured any problems.
