As far as I know the animal has to be able to show that it can recognise itself in a mirror. Whether it's just the animal itself or whether it has to display somehow that it can distinguish itself in the mirror from among others of it's kind I'm not sure.summerof2010 said:That makes sense. And now my imagination is wheeling considering the implications of animal self-awareness. How do they determine such a thing as "self awareness" in a creature, if you know (and don't mind me going way off topic)?
Thanks for reminding me why reality sucks. Oh well, a guy can always dream... I guess.Iron Mal said:Well to answer the question about why you'll never have a jetpack we need to stop and break the idea down into a more basic overview.
You are wondering why no-one in their right mind would mass produce what would essentially be a jet with shoulder straps?
1- It would potentially be dangerous to wear (unless it was designed in such a way as to have the propulsion take place a significant distance away from the wearer, which would potentially result in it being bulky and impractical to wear).
2- It would be heavy, and this isn't just taking into accomidation the aforemention bulky design (nessercary to avoid burning yourself with your own jetpack) but it would also need to have plenty of fuel for take-off, flight and landing (imagine carrying a large petrol tank on your back in addition to a jet engine, you'd need to be seriously strong to lug all that around reliably).
3- It would be hard to steer, this would also result in it being stupidly dangerous to use in any built up areas due to the risk of losing control and/or crashing (being just a jetpack there would be no chasis or frame to take the impact, just your fleshy body).
4- It would be expensive, jet fuel is not cheap (that's assuming it wouldn't need some even more specialised type of fuel that could potentially be more expensive) and seeing as you'd need a lot of it for even a simple flight (depending on your weight I would assume) you'd find it being a massive money sink.
5- There's really no need for it, if you want to fly then we already have the airplane, the helicopter, the paracute, the glider, those weird glider suits and many other ways of taking to the sky (all of which are vastly more practical and don't endanger their passengers and crew for no reason).
As a general rule, if there's something that scientists haven't gotten around to doing yet or something that hasn't been adopted or widely used then odds are on that there's probably good reasons for it.
Cool. If they can get this working then all they have to do is develop atomic transmutation (splitting of atoms to create multiple, less massive atoms) and we'll have an unlimited, renewable fuel source to power the fussion reactors.unlimitedwin said:Yep, currently it's all experimental. I guess that could be assumed from how I wrote that though.Djinn8 said:There are no man made fusion reactors. Fusion is the process of new element been formed by compressing another until the atomic structure of two atoms are combined into one and the excess is fired out as radiation. Gold for example is the result of iron that has undergone fusion. The end result however is very similer to nucular power, which is based upon the use of elements that have undergone an incomplete fusion and are still expelling their excess atomic contents.
They are working on fusion reactors, however and everything actually written in my piece on fusion is true.
Here is the big project: http://en.wikipedia.org/wiki/ITER
I'm not sure about creating gold in a fusion reactor though... Anything heavier than iron requires the energy of supernovae (exploding star) to form... sounds dangerous to me![]()
For those who don't get the joke: atomic transmutation = nuclear fission. Nuclear fission reactors do already exist!Djinn8 said:Cool.

That'll be a real special day for humanity. It really would change everything.
Yeah we might not have got flying firemen, but you know what we did get: pneumatcs to lift platforms and tools that can pry open metal to pull people out. Vans that can deliver those fire men to where they need to be quickly and pumps that can deliver a thousand times the amout of water to a fire than a bucket chain can. In the case of your phone example, also the ability to communicate the need for help in the first place.BgRdMchne said:trolling post
This is completely necessary.BgRdMchne said:I don't need to be psychic to know these things. Just like I know that Jesus will never come back, there will never be peace on Earth, and that coal will never spontaneously turn into gold.
Your life will be a lot better if you take off the rose colored glasses and accept that this world is shit and that science is no longer about innovation and advancement, merely profit and finding better ways to put dumb YouTube videos on a telephone.
You're getting a lot of attention with only four posts, so I thought I'd hop on the bandwagon.unlimitedwin said:As a Science student in University studying Astrophysics and Biology, I can give tell you the actual basic reasons none of these are commonplace.
[HEADING=2]1) Jetpacks:[/HEADING]
Far too energy inefficient with current technology.
We simply do not have the resources to run these on a large scale.
Personal Jetpacks exist, as do flying cars, the issue is providing an efficient energy source in terms of space required for fuel, price of fuel and energy output.
[HEADING=2]2) Cultured Meat:[/HEADING]
Religion and the related "not what God intended" morality.
Like it or not, religion does legitimately hold back science, for better or worse.
There are also plenty of non-religious factors to the issue born of ignorance of the science, i.e. meat being dangerous to consume as it might change our genes or cause other defects. They may be factually wrong, but they can be loud...
[HEADING=2]3) Space Travel:[/HEADING]
Same issue as with Jetpacks: Energy source.
Our planet earth simply does not contain the amount of resources necessary for large scale space travel with current technology.
Fusion technology (same reaction that powers the Sun (and Ironman for that matter...)) is the current main hope for achieving this efficiency, but we are still MANY years away from seeing fusion reactors successfully scaled down to manageable sizes.
[HEADING=2]4) Small Animals:[/HEADING]
Smaller brain = less intelligence.
A creature that requires greater intelligence to survive would die if it were miniature.
There are lots of other biological issues with resizing animals.
Lets just put it down to being cruel, stupid and impractical.
I'm curious how you propose we do this. Personal gain is known to be one of the few things human beings are capable of being motivated by. Maybe we could one day figure out a way to hack into people's brains to make them less selfish, but guess what we'd need in order to do that: more science. Science that there's probably even less motive to push for than any of the stuff Bob was talking about.Alandoril said:I'm with you on basically all of that. The problem is that people with real drive and ambition to change the world are forced into corporate niches and never let out of boxes defined by profit margins.
Get rid of the all-consuming pursuit of money, which technically only has the value we decide it has anyway so it's actually worthless, and we solve that problem. Until then all the pure awesomeness that science is capable of will be sidelined, marginalised and just out-right ignored.
Having to stay within the laws of physics is a "lame excuse" now, is it? The people who "promised" us physics-defying gadgets way back then either were not actual scientists, or were naively assuming that future discoveries would negate what we thought we knew. Well, some of them did, but sadly gravity and the laws of thermodynamics were not among their victims.BgRdMchne said:ITT:
Scientists come and give lame excuses for not giving us things that they have been promising us since the 1910s.
