These three were not  barmpots  but incredible brilliant engineers.

It's so hard to get hold of their work.

 

Obelix,

 

Had they gone off at a complete tangent to the electromagnetic principles that 

we now apply in electronic/electrical engineering ?

 

It's simply the fact that Heaviside, and the rest of them for that matter didn't understand inductance and capacitance especially well. All Heaviside is saying there about his stuff about tubes reaching out into the distances is that when you introduce current to a long conductor - like a telegraph wire - is you have L and C to consider.

 

A wire especially under the ocean has capacitance, that can be corrected for with an approriate inductance which is applied at right angles to the phasor. (which people then confuse and think it's meant literally at right angles to the conductor...)

Is swearing permitted on SF?

It appears you have linked to a copy of a very old copy via YouTube.

You need to watch then edit this clip to remove the repeated use of the F word.

Edit the clip?  That's not how youtube works.

I apologise to anybody if they are offended by the "F". word. I would have "blanked " it out if it had been possible. 

 

Obelix,

Thanks for the insight.

What do you think of the New Horizons flyby of Ultima Thule? Presumably you think that is all fake too (as you seem to believe in any crackpot conspiracy going!) 

 

Why on earth would they bother pretending?

This reminds me of a GPO Telephones course I went in the 1960s. LG=RC for a balanced cable pair. L= inductance, G=leakance, R=resistance, C=capacitance. Lloyd George was a Roman Catholic, was the mnemonic. The inductance was by means of loading coils. The loading coils were removed when digital inter-exchange signalling & speech was introduced.
