Re: Ask a Scientist

I have given up reading on a lot of the theoretical physics because I don't understand enough to try and understand whatever level they're talking on at this point. I also feel as though it may be captivating for those involved but means little for those outside of it.
Every time a news article comes along it's dumbed down enough for me to understand that there has been a new theory of some sort but not any info that helps me differentiate it from the many which have come before.

More power to them, let them at it. Just don't go creating an AI...

Physics, when it starts to talk about a theory of everything, ultimate answers, God particles etc is losing credibility as a science.
Physicists don't call any theory "a theory of everything", or a subatomic particle the "God particle". That would be jounalists and science fiction writers, trying to make catchy names and headlines for laymen to understand and buy their product.

The thing is "theory of everything" sounds a lot nicer than "unifying framework for general relativity and quantum physics", and "God particle" sounds a lot more palatable than "Higgs boson".

I think you might be basing your conclusions on popular science articles, rather than actual scientific works. Physics has advanced tremendously in the past 100 years. Think superconductors, quantum computing, quantum chromodynamics, the gigantic expansion and understanding of the standard model, insane progress in experimental fields such as colliders and ultra colliders that lead the way in our understanding of high-energy physics (that opened up the current discussions about stellar nucleosynthesis)...the list is too long.

BTW, you may want to re-examine your definition of "unproven theory".
...Superconductivity been discovered 1911 by an Dutch, is not new thing, anyway is not feasible...quantum computing still theory, can't be done as the quantum computer doesn't exist...quantum chromodynamics is relate to the things that is so far away that to reach them will take millions of light-years, will not yet capable to do a station on the moon, QC is a phantasy...the gigantic expansion is nearly at the end what else is need to understand, harmonics can tell that...all of this is lalaland...I am talking about that everything stuck on the laws that initial been started by Newton and ended by Einstein putting a limit by law of the energy conservation...we have E=mc2 and nothing more, is no movement from this dead point...

What utter tripe.

Superconductivity is used every day in NMR machines for example.

Quantum chromodynamics is not far away, it is how nucleons work (the stuff that makes up the atomic nucleus).

Einstein actually proved that energy alone is not conserved, only energy-mass combined.

Kiteman, I have a grad degree in Physics, and I did my Masters thesis at the particles accelerator lab of my country's National Nuclear Research Center. Later I specialized in Quantum Optics. But please help me...I have no idea what you're talking about. Where do you get....all THAT ????

Re: Ask a Scientist

...There are a number of technical challenges in building a large-scale quantum computer.[35] Physicist David DiVincenzo has listed the following requirements for a practical quantum computer:[36]

Scalable physically to increase the number of qubits
Qubits that can be initialized to arbitrary values
Quantum gates that are faster than decoherence time
Universal gate set
Qubits that can be read easily...
...So while we haven’t yet achieved quantum advantage, this type of research is the foundational work that will eventually get us there...maybe another 20 years...A large number of candidates demonstrates that quantum computing, despite rapid progress, is still in its infancy...

In your original post you wrote "quantum computing still theory, can't be done as the quantum computer doesn't exist."

Now you admit you were wrong and prove it with your own quote " A large number of candidates demonstrates that quantum computing, despite rapid progress, is still in its infancy."

Infancy is a long way from "doesn't exist"

...NMR spectrometers are relatively expensive; universities usually have them, but they are less common in private companies. Between 2000 and 2015, an NMR spectrometer cost around 500,000 - 5 million USD...feasibility...

...One qualitative prediction of QCD is that there exist composite particles made solely of gluons called glueballs that have not yet been definitively observed experimentally. A definitive observation of a glueball with the properties predicted by QCD would strongly confirm the theory. In principle, if glueballs could be definitively ruled out, this would be a serious experimental blow to QCD. But, as of 2013, scientists are unable to confirm or deny the existence of glueballs definitively, despite the fact that particle accelerators have sufficient energy to generate them...

...Albert Einstein believed that mass and energy can be seen as two names for the same underlying, conserved physical quantity.[53] Hence, the laws of conservation of energy and conservation of mass are "one and the same".[54] Einstein elaborated in a 1946 essay that "the principle of the conservation of mass [...] proved inadequate in the face of the special theory of relativity. It was therefore merged with the energy conservation principle—just as, about 60 years before, the principle of the conservation of mechanical energy had been combined with the principle of the conservation of heat [thermal energy]. We might say that the principle of the conservation of energy, having previously swallowed up that of the conservation of heat, now proceeded to swallow that of the conservation of mass—and holds the field alone."...then is the same conservation of energy...

Sort of but conservation of energy gets a bit messy at the quantum level.
How can you say a certain quantity does not change with time if when you try to reconcile quantum mechanics and general relativity there is no space time or time runs in either direction.
My poor explanation probably has holes as it is all a step too far for me.

So why are you just cutting and pasting from Wikipedia in your previous post?

If you have something interesting and personal to contribute that would be much more useful and appreciated.

Why would he have to if he feels like somebody else wrote it better?

Are you original 24/7 in everything you do?

I know nothing about the mentioned subject so anything posted is better than posting nothing.

Nor sure if your comment was meant as an invitation, it would shut me up.

It would, but clearly it didn't, even when you have no clue about the topic . Being called out for their cut and paste sport will not deter the flying kite from continuing their plagiarizing, just like it didn't stop you from flexing your interfering muscle.

The context is that their previous post was complete nonsense trollbait and now they're just posting cut-and-paste from Wikipedia.

Maybe that's OK, but it seems odd.

It does, maybe the saga will continue and we'll find out. Cut&paste with no source is wrong, totally agree with you, but it is obvious when the language changes from original to pasted. I'd want to find out more.

Nice! If I could go back in time, I would love to re-do university and focus in that field.

There is a quantum optics lab here in Switzerland (maybe it was in Basel, I can't seem to remember) that was designing an experiment years ago to make one able to 'see" quantum entanglement. I wrote to them and volunteered for the experiment, in case they were looking for a 'guinea pig.'

Someone earlier had mentioned something here about "as long as they don't develop AI." I think that's already been developed. Machine learning, etc. Human behavior is increasingly becoming programmed and conditioned by algorithms.

What has feasibility got to do with cost? NMR's with superconducting magnets are perfectly feasible. And not cheap. My last company, Firmenich, in Geneva has a nice one running 24/7 analyzing the results of organic synthesis.
