But these are all experiments to test understanding of the details of theory. Often they go wrong because an insufficient heatshield or the wrong type of alloy is used - it is pretty rare that the outcome of an experiment will result in the utter refutation of an accepted theory.

The therory costs nothing, and besides, while it is true that the failures cost a lot, the successes pay for the failures and then some.

My argument, allow funding to alternatives, before blowing more...
What possible alternatives could there be to the scientific method? Prayer?

Not if we're talking about some magical way of scientific advance that doesn't involve testing theories it isn't, mate

I agree with Brendan, mainly because all you other engies write with such spiflicated spelling that us mere humanists can't decipher what you're saying. (Too much non-euclidean topography, perhaps?)

A thread dedicated to "What are the biggest wastes of money in science, engineering and mathematics?" would be so much more fun.

Must go. My shout.

Let me tell a hypothetical story or two ...
The President of the USA tells NASA they have 100 billion dollars in funding to get man to Mars and back.
Overjoyed, NASA get their best scientists and engineers to build a nuclear engine which will power the space craft. In the process, there are immense problems to overcome and many engineers develop radiation poisoning. Several different working models are tested before they can get one to work effectively. The technology is cutting-edge but goes over-budget by 20 billion dollars. However, all scientists and engineers are proud of their achievement, which has also expanded their knowledge of nuclear containment. On the way to Mars, the nuclear engine overheats and destroys the craft and all its occupants.

Somewhere back on Earth, a few theoretical physicists have formulated a theory that predicts the existence of gravitons and anti-gravitons. Now, this could be just another of those fantastic theories, except that they have devised a test which can be used to prove their existence. The test works. Eventually someone theorizes how anti-gravitons can be produced and harnessed to move a spaceship. It is several decades before the technology is developed to produce such an engine but eventually man uses it to safely travel about his Universe. Oddly enough, it turns out the cost of building an anti-graviton engine is only a few billion dollars.

Don't underestimate the power of theoretical work in science!

Regards, Rob.

I agree with you that "it is pretty rare that the outcome of an experiment will result in the utter refutation of an accepted theory."

how many more gravity antennas will be build

The theories cost nothing... those experiments i've listed, all have been formulated on mathematical-physics, and all have been money pits.

Ahhh yes theories can be as cheap as a can of baked beans but so can the experiment to test it. Why just last week I postulated that consumtion of baked beans along with some very careful sphincter control would be a major advancement in pedagogical stratergy to control naughty children. Just sneak up on them and let nature do its stuff...no need to yell and it brings them to their knees .

Although I am sure this post will be deleated may I suggest anyone who is trully affected by this pointless thread be banished to the naughty chair in my classroom....I need to practice my new theory so I can gain some empirical data as to its effectiveness.

If a bear farts in the bush and there is no one there to smell or hear it did he fart

just imagine if we could somehow capture all that gas my wife always reckons I could heat our house in winter

This is from a purely theoretical POV that should really be tested by you engineering types...

Might I suggest adding cabbage to your beans, energy output should double but sphincter control may be severely compromised.

Note: Any "accidents" involving asphixiation or naked flames are purely the fault of the engineer silly enough to put theory into practice.

I work with engineers and scientists and tradesman.

The scientist is involved with "truth" and so he/she elucidates the principle on which the machine is built.

The engineer applies the principle and designs the machine to put the principle into practice.

The tradesman actually cuts the steel, winds the coils etc and tunes the design so it works.

Who is better? Many scientists I work with have great ideas. They lie awake at night dreaming up better theories.

The engineers get out the Finite Element Analysis software and design the beastie. Oodles of maths, calculations, some funky methods of easily getting an answer from a mess of data ... they devise a way.

The tradies go home at 4pm, and generally have scant time for anyone who can't change a tap washer. Yet their work, the polish and the fit, makes the device do its thing.

The "invention and discovery" ecosystem needs all parts to function. We lean on each other. Respect for each other ought to be part of the mix. But I find that often it's not.

Why are many tradies contemptuous of engineers who can CAD a part but cannot cast it?

Why are many engineers skeptical of scientists whose theories appear as mathematical symbols on paper but which provide the way for their designs to actually work?

Why are many scientists dismissive of the tradies as "self-guiding tools" and the engineers as "pragmatists without appreciation of the universe"?

One size doesn't fit all.

I've known some excellent tradesmen and pretty useless ones. Ditto engineers and scientists. The CAD lot are draftsmen - not what I would regard as design engineers.

Sorry for the bit of a grave dig but I thought this post was excellent and required some further discussion.

One thing I am always quick to point out is that individuals such as Nikola Tesla were not scientists, not tradesmen nor were they engineers, they were inventors.

As inventors they were theorists, engineers and tradesmen all in one package who developed their theories, tested the science and then engineered practical uses for the science they pioneered on their own.

Academic society today is about keeping those things separated and providing the theorists with a sense of arrogance that comes with a PHD and the title of 'expert' which makes them naturally hateful of engineers who tear their perfect theories to pieces to make them work in practical fashion, and neither the engineers nor the theorists feel themselves humble enough to bother involving themselves at the level of lowly tradesmen.

It is extremely rare that I have seen an engineer and a theorist interact in a positive manner without petty squabbling occurring and detracting from the purpose of their collaboration. How can one expect these individuals to advance scientific understanding if they can't even work peacefully together?

As long as there is a divide between these critical elements of discovery and advancement our progress is going to be severely hampered.

Those who have embraced all of the elements have achieved scientific advancement at levels that mystify other equally brilliant but less robust men.

From my perspective the problem with academic and scientific societies today is that mathematical theorizing, engineering and related trades-craft are viewed as being separate entities.

Though specifically in regards to the domination of theoretical mathematics the fact that many theorists today ignore physical concepts entirely and base their theories on mathematics alone is an issue for me.

If you are trying to study and understand the physical world then ignoring the physical world and starting with mathematical concepts is not a good idea; if you don't start in reality you aren't likely to end with anything close to reality.

Mathematics is meant to be used first to describe and then to expand on a physical concept. Hence the repeated mention by actual inventors like Tesla throughout the recent past that mathematics should be the slave to science and not the master.

We have failed to yield those warnings and today the more science "progresses" in regards to cosmology and astrophysics the more disconnected from reality we become.

Just look at the number of mathematical constructs today that are accepted as fact despite having no evidential bases in reality. In fact many of them are theorized to be unable to be observed by human kind, which is extremely convenient. Dark Matter, Dark Energy, Neutron Stars, Type IA Super-Nova, Black Holes, magnetic reconnection/monopolar magnetic fields... and the list goes on.

All of these constructs are the result of mathematical abstraction derived from other things we have witnessed which based on the existing expanding universe/Big Bang paradigm we attribute to being the effects of these mathematical constructs. We can't observe any of these things directly at this time(or ever) but we can see the effects they have on their surrounds so we know they are there...

The fact these things can be explained more completely and easily with theories that are derived from paradigm's other than BB theory is ignored as it doesn't fall within the paradigm that has been taught to you and thus it isn't real science. These alternative theories can attribute direct evidence with their theories rather than just indirect evidence and mathematical constructs but apparently basing a theory on evidence has become a foreign concept to modern "science" so much so that it's not considered science at all.

Believe it or not most credible alternative theories have lots of mathematics to support them as well, the reason people like myself tend to give them more credibility than conventional/mainstream theories is that those alternative theories are typically based on observational evidence first with the mathematical formulas derived to support the evidence - mainstream far too often has their theories based entirely on mathematics and the evidence is simply interpreted mathematically in a way that fits in ad-hoc fashion.

For me evidence(reality) comes first and mathematics comes second.

Note: This is an opinion piece so I'm not providing any sources, though alternative theories on those constructs I mentioned(black holes, dark matter, etc.) can be linked if requested but most if not all here would probably dismiss them simply by their sources.

Unfortunately not many mainstream sites will host these theories and the few "fringe" sites that do are viewed poorly and given no credibility, which is a rather convenient way to silence dissent - you only have credibility if the mainstream gives it to you, but they won't give it you unless you cloud the whole thing up in a political manner to prevent any respectable scientists from having their toes stepped on and in the process most of the theory is "lost" and the bits and pieces that remain are easy to attack.

If you don't want to or can't manage to do that then you are a quack, plain and simple.

I can understand why the truly "out there" ideas would not be a good idea to be given serious attention in the public domain to prevent people from being "influenced" by them but there are many alternative theories that have a credible basis and should be open to discussion in the scientific realms.

Surely intelligent scientists aren't going to be easily "influenced" by something they read or discuss a few times. NASA has remained reluctant to publicly give any credibility to the idea of non-neutral electricity in space yet they have created a 'Space Weather' division to study electrically charged particles in space and just a while back invited one of the chief proponents of The Electric Universe Theory to talk at one of their facilities.

If they can trust their people not to be unduly "influenced" by such discussions why can't such discussions be freely partaken in on scientific forums?

Growing up in a devoutly religious society with a rebellious nature free and open discussion is what I was led to believe was the hallmark of the scientific community, but all I've discovered in the mainstream community is more religion with mathematics as the supreme deity.

In my experience the only thing free and open discussion is welcomed with is proverbial pitchforks and wave after wave of ad-hom attacks and character assassinations.


I'm sorry for getting into a rant but there's been a lot of discussion on these matters across many threads that I've seen here and I decided to just add all of my thoughts on the matters into a single post here rather than spreading bits and pieces all over.

Plus it's easier for anyone who wants to disagree with me on it to have it all in one place.

Hi CosmicKid, in some ways you have expressed much better the problems that some of us are having with today’s Cosmology and theoretical physics then I did when I started this thread.

"It seems that main focus of current cosmology and theoretical physic is on proving why something is not possible..."

Well, I hate to be the one to break it to you, but that's almost called "science". Where you went wrong with that sentence was when you claimed scientists attempt to prove things. Scientists don't and can't. Detectives and mathematicians seek proof, not scientists.

I'm afraid you'll find that these are very real, and quite observable features of nature.
