We know 5% of what we will know in 50 years time (those that are still with us of course)
Sobering thought.
Might even apply to hifi gear......

How do they know that though?

Extrapolation I'm sure  |

How do they know that though? I knew someone would say that. |

Slinger, are you saving everything?

I think he has to, or he'll have forgotten 95% of what he's going to know in 50 years time.

I have no idea why that "Save" appears every time I edit a post. It's rather annoying.

Longer answer to Chris.
Reliable source so far as I remember : We know some vast percentage more than we knew 50 years ago and it is increasing quickly so the 5% seems about right.

"There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know."
Donald Rumsfeld
and in my opinion 99% of the Universe comes into that last category

Agreed. You can choose to be comfortable with what we don't know, striving ever forward to know more. That's called science.

I've been saying for a long time there's a hell of a lot of stuff scientists don't know. Of course, that was the wrong thing to say in a cable thread |

Any sensible scientist would agree ! Keeps them employed too The more I learn the more I find I don't know. |

Fantastic stuff like this is happening with greater regularity I think, but we often don't hear about it unless or until a physical application is found. And now, here's Steve. |

I want negative mass mains cables There's been a few things we don't know being found by people posting on Facebook and the like. Seen great apps for mobiles invented in Africa. Real steps forward |

The thing about the unknown is that scientists embrace it. It's ok to accept that there's a lot we don't know or understand.
Only the scared or closed-minds create a belief system as a substitute.

Rambling on my mind on the bike ride today.....
50 years ago, 1967 if me sums are wright.
Stereo was new.
There were stereo systems but they must have been very rare.
My mum and dad had a *stereo* radiogram.
So far as I know the only discussion being had was how speakers sounded different.
Our next door neighbour was into music and had either Nikko or Onkyo with home made speakers.
My current setup with al the accessories would be science fiction

Arthur C Clarke said that any sufficiently advanced technology is indistinguishable from magic. Seems that 50 years is about it, then!

Some say, only know what you know!
For me, that doesn't stop you continuously finding out more, to know.

Unfortunately, younger generations learn more and more useless things but none of the essential how things work that my generation learned.
They may 'know' as much but it's less useful to them in the real world.
