A 25-year old brain may have more raw "horsepower" than a 45-year-old brain, which would make a big difference in math and physics, but wouldn't matter as much in e.g. poetry.

Most countries with socialized healthcare systems that I am aware of actually has a longer life expectancy than the USA. This is true for Canada, Germany, Norway, etc. I do not know if life expectancy is a measure for quality of health care, but it is at least an indicator of how good the general health is. On a personal note I would say that my experience with the US health care system has left a lot to be desired,…

I do not know which insurance is great and how many people has access to this. I do however know that when I tried to read my plan, the legalese was so dense that it such as well have been written i Japanese.
My University of California at Davis group insurance plan costs $500 per quarter, and that rate is given for a pool of generally healthy young students. Do you know what a startup person has to pay for a great health care plan? Is a obamacare plan good?

But Thoreau also wrote of the value of living in the moment. So don't get too worked up about the destination.
That's not contradictory to what the quote says. In fact, "do it now" is pretty much exactly what he's saying when he says most men die with the song still in their heart. Moot point however, the quote is a missed one. He never said this.
Not so very much different.

Hi! I'm a mathematician, I've always been curious about physics, but I've never understood some of the concepts of QM, such as what is "observation" in the Schrodinger's cat paradox, why QM means the universe is not deterministic, why hidden variables cannot exist, ... mostly because every physicist that I was able to talk to has been unable to properly explain these concepts. Do you know any books/articles/sources a…
Tough question. The reason you probably did not understand them is that there are reasons are faulty. The textbook QM says that when experiments happen, the continuous wave function evolution stops and a new wave function is used in its place, chosen randomly based on a prescription using probabilities coming from the original wave function's decomposition in terms of an operator's (matrix) eigenvalues. This is a pos…

By CPI deflator, $100 in 1969 is worth $634.76 today. http://www.usinflationcalculator.com/ Not sure if that calls into question your statement, or suggests that the CPI is drastically understating inflation.
By CPI deflator we never doubled our (US) monetary base since 2007.

If you'd read the book and worked through it you would understand why a hidden variable theory is not experimentally justifiable.
In as much as QM makes predictions, pilot wave theory makes the same predictions. But pilot wave theory has the advantage of being an honest theory that actually does make predictions. QM suffers from needing an external agent to collapse the system, an agent that is never specified, particularly on the universal level. Bell puts it very eloquently about whether one needed to wait for the first form of life to do it or perhaps one with a PhD to collapse the universe. He concludes it must be happening more or less all the time and that the mechanism needs to be explained in the theory. We can either change Schrodinger's equation as in GRW or we can add additional variables such as positions of particles as in pilot wave theory. Or we need to accept that most of reality is unlike our actual experience of a single reality such as in many worlds.

I think you have a larger problem though. A theory is (as Heisenberg explained in his book "Physics and Philosophy") an interpretation of data based upon unscientific, non-falsifiable, a priori assumptions on the part of the theorist. You can't really disprove something as nebulous as "hidden variables." That's not a falsifiable statement. What you can do is disprove some theory based on hidden variables. Such eviden…
My understanding is that any sort of local hidden variables have been ruled out (at least, if you want to preserve causality).
"Chaotic Ball" model,local realism and the Bell test loopholes.

> Actually Poland which is 2nd world country really, has better life expectancy that USA! Which is easy to explain the US also being just a 2nd world country. The difference is that the US standards are falling and the other 2nd world countries are mostly rising.

Yes, I agree that the USA is the best healthcare system for people with money and/or great insurance. I do not know which insurance is great and how many people has access to this.

A distinction I read somewhere, that I think is useful, is that people tend to be either primarily conceptualist in their thinking, or they are empiricists who learn from experience. Conceptualists have their big breakthroughs before the age of 35, and empiricists have their big breakthroughs after 35. In conceptual fields, such as math and physics, the big breakthroughs happen young. Werner Heisenberg was 27 when he…
