Einstein called chess a waste of time, what do you think?
Sort:
Chess does not make any money for the vast majority of players, hence why it is a waste of time. But for own personal development and entertainment, it's one of the best. A skill like art, or music....
Einstein was correct--chess was a waste of time for Einstein.

einstein was a copycat pysicist.
for cexample e=mc2 was found before him by Poincare
this would be true if every person has same interest and goal in life as Einstein ok.
Chess is a waste of time for most of us, just like watching TV, reading a fiction book, playing a video game, etc. We don't work all the time, we also play, and chess is a form of play. Of course some of the worlds best players make money playing.
Yup. If I had a brain like Einstein's I might think the same too.
But given that I don't... I might just keep at it for a while :-P

As Einstein once quoted chess was a waste of time for him, he only played it to relax from his exhausting studies of physics. Do you think it is a waste?

No, it wasn't. Poincaré found the operator group that generates all the transformations necessary in theory of relativity to change between reference frames. What Einstein did propose was the 4-vector formulation using Ricci calculus, and postulated that the speed of light is unchanged under Lorentz transformations and is frame invariant. Einstein then generalized the Euler-Lagrange equations of motion to account for the Lorentz transformation, and he found that the total energy is proportional to the scalar component or temporal component of the 4-momentum. Then, by using the Minkowski inner product, he found that mc^2 is a Lorentz invariant. Furthermore, since the conservation of momentum implies that p = ymv, where y is the Lorentz factor, this means that inevitably E = ymc^2. However, when v = 0, y = 1, so E = mc^2 is the rest energy of the object. This is what Einstein proved, but this is a small consequence of the larger theory he proposed.

And many people think that his wife was the co-author of a lot of his work, but she didn't get much credit for it. Nothing new there... :-(

Well, he did do his best work in a vacuum.
That's a patent lie!

Debatable.>>
It's just wrong. Hardly debatable. Einstein may not have been the brightest star in the intellectual cosmos and he was certainly very fixed in his views. He was stupid on some levels.
When I said debatable, I was referring to the former claim in the quote, not the latter. This is my fault for not clarifying.

And very notably, Einstein didn't credit Maxwell and others, which was a bit fraudulent in itself, even in those rather lax times. There's no doubt that had he acted the way he did these days, he'd be in prison for quite a range of crimes.
Okay, this is just false. I understand the fact that he probably didn't admit his wife helped him, and I understand he wasn't the nicest person in the world, but he did credit Maxwell and other physicists who contributed to his work alright. In fact, the literal fundamental postulate of special relativity as Eisntein proposed it was that the equations of Maxwell were true in all inertial frames of reference. In doing so, he credited Maxwell. Listen, I didn't go to university to study his theories and read the papers and review its evolution just to have a couple of conspiracy theories saying he didn't credit the people who provided the theoretical foundation for his theory to be possible.

I agree.
From what I've heard, Einstein quite enjoyed the game of Chess, and was somewhat "good" at it.

Einstein greatly respected Maxwell, and recognised his crucial position in the history of physics, second only to that of Newton.
He said:
"The special theory of relativity owes its origins to Maxwell's equations of the electromagnetic field."
He also said:
"Since Maxwell's time, physical reality has been thought of as represented by continuous fields, and not capable of any mechanical interpretation. This change in the conception of reality is the most profound and the most fruitful that physics has experienced since the time of Newton"
Viewed from a century later, Einstein was dead right.

Well said! I'm not saying Einstein is a moral role model, but credit is given where credit is due!
