Thanks WG, I see that you've made many comments with good approval. I'm not attempting to put out a paper, this is a forum, for ideas not proofs. The "does it come from the math" is a bit blithe, dismissive even. There are dozens of inflation theories, each with a parameter space in a...

The idea that the universe has an overall angular momentum is possibly worth exploring further though - it could be a form of MOND that might account for dark matter/energy? We excuse the fact that inflation does not conserve energy, and that it expands faster than light, why not add that it...

1) it's common for gas discharge tubes to have a radioactive component, it helps them to strike at a lower voltage - see wikipedia on neon bulbs which use Krypton-85. In this case they don't want the extra spectral lines, and have used doped glass. 2) Can't get them to light? - try...

to the Original Poster, OP, the terms are identical in meaning, any form of words mentioning First Principle(s), will be talking about the same thing. Often, First Principles are used to describe a simple understanding, and an expectation - only then to contradict it with the reality...

You used to get e-gun tubes with a mica window at the end andthe e-beam traveled through air, for a cm or a bit more - much like beta radiation. The route to a general answer is to look at the attenuation vs distance at different pressures - and work out what attenuation you can stand, is it...

A large proportion of the "shipped silicon" is in designs < 100 transistors - like all opamps and regulators, linear and switch-mode. Larger designs will all use standard "cells" - like SRAM, DRAM, Flash, CMOS image sensors, - even full-blown VHDL uses standard logic cells - AND OR NOT etc...

ooh, not sure you were complaining about having to learn stuff... ? The KVL and KCL are the basis of Pspice, whether with just resistors and capacitors, or with semiconductors However even the diode equations are quite complex, transistors are a lot worse, so we either use pretty basic...

this sort of thing - the bearings do not puncture the sphere. as you can see, if the pipes don't extend into the centre of the sphere then water will come out, and the duration will be short.

nice thing about the simple approach is that if it's a bit off-centre, wobbly, then you can change the axis points with a hammer - just deepen the indent a little as you move it a few mm in the desired direction.

The original did not rely on gas-tight seals, as far as I'm aware. The bracket just "pinched" the sphere, much like they picked-up big stone blocks in those days - a couple of indents and some pincers. The sphere had pipes that went roughly to the middle - to get steam without water, and the...

1N4004 is fine, strictly you should replace 403 with the same part (variations in Vf might affect the 50:50 purity of the triac conduction, resulting in DC then saturation in the transformer) shouldn't matter much tough the thing is "digtally" driven, the opto-coupler here...

I understand that the amplifier is a class H or similar. These classes (there are many subtle variants) are trying to get round the problem that even class B is inefficient at half power, the output stage powered from say 50V is dropping 25V even at the peaks. The solution is for the rails to...

Thanks big Guy...:)

Come on bigGuy, I'm not at fault here, you've only quoted half what I said : Actually TR401 is a triac, which is just a pair of thyristors in antiparallel. The idea is that you switch it on some way through each mains half-cycle, and at the zero crossing, it switches itself off. This will...

I've had a look at the circuit, briefly, there is is useful block diagram also, this part is "AC control" it is a thyristor driven transformer, I don't know how familiar you are with thyristors, basically they are an arrangement of transistors exactly like Q402 Q403, and when turned on, they...
