Can both centuries be compared to each other in technological advances. Steam power must rank up there with the greatest of all advances in the 19th because really it kicked off the industrial revolution. Nearly everything from railways to factories was steam powered. Great engineers from Stephenson to Brunel to name but two. You can only skim the surface on all the advances in the 19th.
The 20th saw the development of the motor car. The first aeroplanes. Television and it goes on and on even to the end of the century with the internet. What do you think was the most inventive century of the two. Even look how we have developed so far in the 21st. I would opt for the 19th though I wouldnt liked to have lived then. _________________ The Clan Chieftain |

I think that technology builds upon itself and so the rate of progress is increasing with time.

In terms of impact, the arrival of steam power did change the lives of the civilised 19th century world. The 20th century has to the most prolific in diversity of inventions. In modern times I would nominate the developments in electronics as a modern world changer. Since the invention of the transistor in 1947, electronics has changed the lives of everyone to a mind boggling extent.What would life be like without them.

The 20th century saw both the invention and the development of the integrated circuit. Thanks to the huge / massive investment made by the U.S Government for both the defence and space programs, we now have electronic devices where the cost of advertising, packing and shipping is greater than the content.
I am not sure that our modern motor cars need the level of electronics that they now have, seems that after it was decided to include a computer to control the engine there was a no limit approach.
Pre-delivery "transit mode" may keep software writers in work, but does the world really need it ? and what about the GPS / systems linked non erasable data. If it ever goes public there will be no use saying you were at work, when you were actually at the Pub. Or horror's even worse places
Have we actually lost control of ourselves. ?
and getting back to motoring, have we long passed the golden age of producing motor cars that can be saved from someones back yard and lovingly restored using our eyes and mechanical skills ?
Are the vehicle restorers of today, the dinosaurs of tomorrow ? if so, keep the photos of people actually repairing something, because in thousands of years, our minds amd limbs may be incapable of such things. |

Interestingly it's not normally the electronics in modern cars that that cause problems but things like dual mass flywheels and injection systems operating at pressures of 1600bar (yes 22,000 psi!!!) that require system cleanliness from better than 2 micron filtering. i.e new fangled mechanics not electrickery.
If we want high performance, low fuel consumption and less pollution then we have to live with it.
The biggest problem for future classic car owners is not inability to deal with the technology but simply the commercial secrecy of the motor industry.
We can only hope that information is released in years to come.

Lost me already on this one... What on earth is a dual mass flywheel, and what's it supposed to achieve? |

to put it simply it's two thin flywheel's joined together with a vibration absorbing substance in between mainly meant for diesel's, they can start to break up and cause a lot of problem's to starter motor's and flywheel sensor and clutch, can be replaced with a normal type but one can also get trouble from doing this with crankshaft's breaking and or bell housing cracking not cheap to replace either but a lot of vehicle's have them. |

Thank you for the explanation Churchill Johnson and it's a sore point with me at the moment because it looks as if the DMF and clutch on my Discovery TD5 will need replacing soon, an expense I am not looking forward to as it's beyond my DIY skills.
As for the engineering and science of the C19th and C20th centuries, I reckon the honours are shared between both. _________________ Starting Handle Expert

Very true. Where will we be, I wonder, by the end of this century? Probably spending more time, money and effort on developing ways to combat diseases of the elderly than ever before as most of the population will be over 100! |

Thanks for that. Sounds like a pain in the bum and another excellent reason not to touch modern motors...  |
