TOPIC: What do undecidability and unpredictability mean? by Martin van Staveren [refresh]

Essay Abstract

In natural science and in technology, decisions are commonly taken on the basis of uncertain information. Since three decades Bayesian estimation has become quite popular in technical control methods and in the interpretation of uncertain information. Physics is more like technology than like mathematics.

Author Bio

PhD in experimental physics (Leiden) in 1989, thereafter work at the European Patent Office in a.o. the field of error correction coding and decoding (CD, DVD, BD), thus meeting information theory (Shannon), which clarified a lot conceptually.

Dear Professor Martin van Staveren,

It was nice 'paragraph essay' filled with facts!!! Your words........The problematic situation of foundational physics is that it is caught between formal mathematics and technology. So in a realistic sense undecidability and unpredictability are the normal conditions of life, ...... Physics is not mathematics. An alphabet is not a book............

I just elaborated what should be the freedom available to an author when the “ real open thinking” is supported. Have a look at my essay please.

“A properly deciding, Computing and Predicting new theory’s Philosophy”

Dear Satyavarupa,

Thanks for your reaction. I agree that superstition etc should be avoided. That is the subject of Bayesian probability. We should Not believe everything, but not everything can be 100% certain, either. So how do we take rational decisions? Quantum theory is accepted because it works extremely well and it is rational to do so. Do we really understand it? What does “understanding” mean?

Respected Prof Martin van Staveren,

Thank you for reading my essay, First of all let me clear one point, that Dynamic Universe Model mainly works in Cosmology and astrophysics.

According to this model, all the decisions are taken after computer calculations and simulations. That way they are "Rational Decisions"

In this N-Body problem solutions based on the Philosophy as mentioned in my essay, we will do data-mining and graphical visualization for understanding the large amount of data which is sometimes in millions of records. To down load my papers and books freely please visit the blog...

Dear Martin,

I have seen estimates that it would take coverage of about one percent of the earth’s surface with solar to generate all of the power that man currently uses. If it is done right, much of this area could come from already used land areas, such as on houses or...

ear Martin van Staveren I have a return comment to you ready to send, but I can’t login to my account because it says that it does not recognize my email address. I will get it to you if FQXI gets the problem fixed. If you or anyone else wishes me to send any answers to any comments you send to me on my paper’s page before then, you can put an email address in the comment to me and I will send my comment to you that way. This puts me at a great disadvantage in this contest, since you can’t make any comments to anyone without being able to first login to your account.”

Sincerely,

Paul

Respected Prof Martin van Staveren,

Can you please send me a mail to my id " snp.gupta@gmail.com ", so that I can send Dynamic Universe Model's new paper to you on "Cosmic ray origins " for your learned comments???

I dont know how to send that paper via this forum....

Dear Martin

In my thread you left a comment where you mention that:

Writing a function as F(x,y,z) does not mean that F really exists in physical space, even though x, y and z seem to refer to physical space

My reply is: The electron density
$\rho(x,y,z)$
depends on the spatial variables, and exists because electrons exists, so if the density exists why not its mathematical representation? The problem as I argue in my essay is that we most people think that what exists is what we can detect with instruments and/or our senses but that just half of the story. I think you should first start by telling what you understand by "exist". I would be glad if you read my essay.

Regards
