Re: Why Are There No Right Angle Traces?

I have done layout on a lot of boards. To me, looks really do count, both on placement and routing. No self-respecting layout person would create an ugly board. They don't call it "artwork" for nothing. Also, having unnecessary vias is just plain wrong. Even though it really doesn't matter most times, I spend times to make the board look like it was purposefully designed. If it looks "pooped out" it probably was.

I remember once the boss was going to lay out a board himself. It was all in 90deg traces. Ugly as hell, and didn't work - not because of traces, but because of other errors.

Have you done the measurements or the calculations? If not, your "feelings" are rather unimportant.

Let me ask, how fast do electrons travel? What is their kinetic energy? Is this important? If so, when?

I'll buy that. Let's call it marketing one's self. How much money is put into packaging breakfast cereal?

More than the cost of the food put in the multicolor pasteboard box.

As Albert Einstein already said that only a beautifully looking formula can be a correct formula (I don't remember the exact phrase), only a beautifully looking piece of hardware will function flawlessly.

Of course, we all know that this is not necessarily true. I don't know whether there are some statistics available, but I think there is at least some truth inside.

Apart from all the technical issues involved (i.e. in this case by right angle turns), a designer that does not put any attention on the appearance of his design, does probably also not put much attention on the general design as well. As a result, it will show up some flaws. Therefore we might have some coincidence here.

I think this does not only apply to electronics.

Er..Ahmmm.. this is not a good one either. It appears that this particular "confirmation" is not really supportable. There errors of the measurement were not low enough. Of course, the bending of light has been confirmed with much better precision nowadays.

It is better than you think. The anomolous perihelion advance is known to +-0.45 arcseconds per century and is 45.11 arcseconds per century. The GR value is 43.03 arcseconds per century. The remaining error may be either a need for a more accurate theory or errors in the less well known numbers in the GR calculation. The measured number must be considered accurate to at least the stated error band.

The precision of astrometric measurements is so high that these are the best confirmations of the theory aside from radar measurements.

I was referring to the bending of light, not the proof of the absence of the planet Vulcan. imo, a rational examination of Eddington's experiment is that it meant nothing.

Copper IC metallization is already operating in the MA/cm^2 range. The whole nanotech/buckyball/nanotube thing is massively overhyped. Somebody is claiming a nanotube-based RAM...

which just about pins my bogometer needle.

I take it you're not likely going to be investing in the inevitable IPO..

I happen to know some of the VCs who are funding this, and have seen the sort of corporate paperwork they like. I assure you that nobody (not the employees with options, not the angel investors, likely not the founders) but the VCs will get anything but screwed.

Yes. The effect to be measured was close to 1 arcsecond and the probable error was about 0.25 arcsecond. It was a start. Much of the error was due to having to leave the camera in position for some months in order to get several night time plates of the same stars. The focal length of the camera changed slightly due to temperature change from the time of the eclipse to the time when the night plates were taken. Today, the optical experiment can be done to milliarcseconds without an eclipse and without waiting for months to get baseline stellar positions. The radar experiments are even better.

There's also the fact that a diagonal line is shorter than two orthogonal ones, and a "diagonal bent" bus will occupy less PCB space.
