Evidence Definition and 355 Threads

Just a simple question for people knowledgeable in biology: what are some specific examples of determining someone's age by studying their body? I know you can use bones and teeth, and perhaps hair or something, but what specifically is it that the coronor, let's say, looks for to determine...

What are the methods currently being used to date the Earth and/or universe? I was talking to a buddy and he was on a role about 10,000 and the age of the Earth and the unreliability of carbon dating. What are some of the methods now being used? Nautica

In L. I. Schiff book, one can follow his derivation of the Hamiltonian from Dirac relativistic equation and obtain the following.. \left[\frac{\vec{p}^2}{2m}+V-\frac{\hbar^2}{4m^{2}c^{2}}\frac{dV}{dr}\frac{\partial}{\partial r}+\frac{1}{2m^{2}c^{2}}\frac{1}{r}\frac{dV}{dr}\vec{S}\cdot...

https://www.amazon.com/gp/product/0761519645/?tag=pfamazon01-20 I know it is not a science book only and maybe there is not too much to discuss here, but I just wanted to know if anybody has read it. If you have, would you share your opinion please. :)

I have a question that asks for experimental evidence for Einsteins famous E=MC^2 equation that isn't from an astrophysics, but the only evidence I can think of is nuclear fission, but I'm sure this occurs in stars in some way. Would this count as evidence that isn't from astrophysics or would...

I had little interest in some thing written by Homer 500yrs after the fact, prefering to think the Trojan war a myth, however archealogical evidence is giving some bones to the the myth, i guess we will never know if there was a "wooden horse" or if the characters in Homers story took part in...

what evidence do we have that everything in our memory is stored? and what evidence do we have against it?

http://xxx.arxiv.org/abs/astro-ph/0508572 I like the way the title of this paper captures ones attention. For a minute there I thought they had finally found some evidence for string theory. From what I understand they’re speculating on astronomical observations of dark matter, by...

Double slit in time experiment. http://faculty.physics.tamu.edu/ggp/#doubleSlit http://physicsweb.org/articles/news/9/3/1/1?rss=2.03Cbr20/E This surely is experimental evidence that that matter/energy is not just quantised over spatial dimensions (as shown by the classical double slit...

http://uk.arxiv.org/abs/physics/0412039 Sounds off base to me, but I'd welcome an informed critique.

What kinda experiments prodive evidence that SC resides in the CuO layers? Off hand I can't think of how any experiments that I'm familiar with could distinguish if the CuO or another plane where SC. Thanks

Evidence? What evidence do we have, but what the "experiential mind" dictates? Doesn't that in effect suggest it's not possible to know anything outside of what the mind knows? If so, then how do we present the evidence outside of "the context" of what our minds perceive? I mean how exactly are...

This is a subject i'd like to become a lot more educated on. I've seen a lot of science vs religion discussions on various other forums, and a lot of religious fanatics making statements about the flaws in accepted scientific theory... a lot of which I'm skeptical about, but unfortunately I'm...

Ive started to hear a lot about this 'higgs' particle recently. Any chance sum1 can explain to me what the particle is/does/comes from etc?? any help would be great. also what are the implications of its existence?? :confused:

Because it's the best kind of evidence! Now there's some rock hard stuff!

what evidence can support the idea that light can travel through a vacuum?

Is there any solid evidence for true randomness in in the universe? Or is it with everything more the idea of "we could theoretically predict it if we had ALL the information"? Is everything thought to be essentially deterministic at some level?

Hello all. I've recently had something of an epiphany regarding relativity. One of those moments when things become clear and it all makes sense. However, having not actually performed any of the experiments which may or may not support the whole thing, I have a question. Is there evidence...

Jim Bohannon was a radio guy who took over the airwaves when Larry King left for television stardom-the guy actually read headlines from WWN and 'scouffed' at the 'ignorance and gullibity of people who believe this nonsense'! Every week! (of course, the Washington Times would be the latest...

I am not sure what forum category this should go in, but since Cahill's paper (see abstract and link below) claims to be the first evidence for discrete space, which of course supports LQG, this may be the appropriate location. I searched the Physics Forum for Cahill and got zero hits. His...

If God does exist, then the evidence is all around us, you knuckleheads! So what if the probability of life on this planet began with a couple of flashes of lightning in a pool of water (or, a myriad of lightning flashes -- each time rearranging the molecular structure of the water -- over the...

In the standard model, there are three families of matter particles, headed up by the electron, tau and muon, and their associated neutrinos, and quarks. Is there any reason to suspect the existence of a 4th or even 5th+ series of matter particles? (which, if they existed, would probably be...

I may have mentioned this problem in a thread on the old PFs, but I don't remember the answer, and I can't use my Archive C.D. right now, so I figure I should ask again (I'll probably get some new responses anyway): What evidence is there for or against the idea that a giant "water canopy"...

This paper on the new quantitative biology section of the preprint arxiv claims evidence in brains of living rats of chaotic behavior matching that of a well known theoretical model of chaotic quantum mechanics. If verified, a true breakthrough.
