I don't get the Theory of Relativity

[Yayfordoritos]

How did it become so famous when it's so hard to understand?

 

[Ivan92]

I know huh?!

If you think relativity is hard, you don't really understand quantum theory.

Why does everyone always pick on relativity theory?

 

[uperkurk]

I think this might help you. Although I get confused between general and special relativity.

How did it become so famous when it's so hard to understand?

Because it's correct (at least more than Newtonian gravity and Galilean relativity). Maybe one day, something will come along more correct and harder to understand (some kind of Grand Unified Theory), but for now, Einstein's Relativity is the best way we have.

Some would think it the theory to be infamous.

 

[FreeMitya]

Speaking as a layman, I think it's simply the way one thinks. I'm sure many people are better suited to study relativity than QM and vice versa. For example, I've been much more successful at grasping relativity than thermodynamics, but many people probably experience the reverse. If you're worried that you're less smart than anybody else for having trouble with relativity, don't be; we all have our niches.

I'm one of those people who wants to be smart but never will be lol. I come here to read stuff I don't understand, even though I don't understand 99% of physics I still find it interesting :)

It actually became famous for being so hard to understand. The saying used to be that there were only twelve people in the world outside of Einstein who understood it. To which Arthur Eddington asked, "Who are the other eleven?" (Eddington was the main promoter of the theory. He called everyone's attention to it.)

According to the National Science Foundation one in five Americans still believes the sun revolves around the earth. These are not the sharpest pencils in the box, but inventions like the atom bomb tend to get their attention.

I can't believe that. We're bad, but not that bad...

Oh? Most people think that the summer is hotter because the Earth is closer to the Sun then. About half can't find the USA on a map of the world. About 15% think that the Gulf oil spill was the result of an environmentalist plot. Etc. Etc. Once one grasps these basic facts, politics makes a lot more sense.

Well, at least Palin didn't become Prez US.

It's true. Sometimes I wish only the intelligent could vote, then I realize what I'm saying and stop.

Mainly the south?

I've often wondered that. My guess is that it is because few people learn it in high school and high school physics is as far as most people get. So if/when they encounter Relativity 5 or 15 years later, they don't take it seriously because they didn't learn it from The Foremost Authority on the subject that they have ever met.

I don't know, but it seems reasonable to me to assume the more impoverished the area and the greater the classism the lower the scores.

That's true! I moved around a lot when I was a kid and a couple times we had to live in the poorer areas and I ended up excelling academic wise in those areas, but when we moved to a more affluent area, I had to struggle to keep up just cause they were so much more advanced. I remember Oprah did a show on kids who did extremely well academically in the impoverished schools and then went to College and were struggling just to pass.

The advantage of universal sufferage is that it gives the public the illusion that their voice is important. This gives the society stability.

I remember some guy on TV giving George Carlin a hard time when George said that the voters didn't "own" the country. "George, how can you say that the voters don't own the country?" Good grief.

Simple. It works.

 

[collinsmark]

I've always liked Leonard Susskind's introduction to this topic. Listen to the first 5 minutes of this lecture:
https://www.youtube.com/watch?v=0Eeuqh9QfNI
The lecture in the link isn't about relativity specifically, but it does bring home the point.

 

[Jorriss]

Mostly because of E=mc^2?

I hope this is not straying from the topic, but what class is general relativity usually taught in? I've had special relativity in modern physics and I have to agree it was very special at first...my brain was total mush because I kept missing the point of one important sentence.

 

[PhizKid]

General and Special Relativity are usually courses in their own

 

[HeLiXe]

I've never heard of that, but I digress. I will ask the question in the academics section so as to not take this thread off topic. Thanks for your answer PhizKid

Over the years I've learned that knowing or understanding the theory of relativity isn't really all that important.
People who do not grasp it or its relevance, are usually much smarter than they get credit for.

According to the definition of capitalism voters don't necessarily own the country, they merely have a say in how things are run. When voters do own the country it is called "socialism". It was an American railroad and banking baron, Jay Gould, who said he could pay half the working class to kill the other half. He could have been a felon with no voting rights, but he had enough money to lobby congress, fund elections, and plaster political commercials everywhere. There is no doubt such people own the country and their influence is beyond that of the ordinary voting citizen. Money talks, size does matter, and anyone suggesting otherwise is living in an ideological fantasy.

Whatever goes against the common intuition of general public ... and is also proven to be correct ... becomes famous.

I've never heard this. What's the proof you speak of?

 

[nitsuj]

lol did you miss the context zoobyshoe?How about the Earth is round, sun is at the centre of the solar system,

nowadays - slit experiment, and pretty much all else QM.

These become "famous" generally because they "goes against the common intuition of general public ... and is also proven to be correct[.]"
