There's formulations of grease that don't do that, of course; silicone takes high
temperature, and some greases are intended for electrical conduction in thin
films (they 'break down' at millivolts, and don't even get hot).

I've used this grease on rotating connections, at 40A it's just like
a solid wire connection.

Around here people wear neon colors when their biking. I don't think
I've seen anyone wearing black shorts with a red shirt yet.

That might be one answer to the conundrum, that drunk driving enforcement
and cultural changes *exactly* canceled out the skyrocketing cellphone
ownership figures.
 
However, for it to have exactly canceled the rates, both the timing of
drunk driving changes and the timing of cellphone changes have to agree,
in addition to the rates of each have to exactly cancel each other out.
 
I think, while that is possible, it's highly unlikely; but, that is yet
another possible answer to the enigma that the cellphone-caused accident
rate doesn't seem to exist - all the while we *think* that it should.

If a quarter of all crashes are "related to cellphone use", then
why aren't accident rates going up by a quarter?

I think you have a problem with large numbers.
 
If the accident rates, given the tens of thousands of accidents yearly,
aren't changing, then it would take a stupendously stupifyingly
coincidental alignment of the stars to then make the accident rates
exactly cancel out the *entire effect* of millions upon millions
of cellphones being owned (and presumably used) by almost every
person of driving age in the United States.
 
That your *entire argument* is based on refuting yearly accident
rate figures based on a minor estimation detail, is unbelievable.
 
Do you realize how MANY cellphones there are owned by people in
the USA?
 
If those cellphones were being used, while driving, and if they were
causing accidents, no amount of fudging of the data would show what
the data actually shows.
 
There is a paradox, to be sure, but the answer is never going to be
found in the puny numbers associated with *estimation errors* that
you want it to.
 
You're grasping at straws if you truly feel that the *estimation
errors* exactly cancel out the absolutely stupendous effect we
presume cellphone ownership to have on accident rates, in both
timing and in number.
 
It's just not possible,and, it's a bit scary that you believe it
is. Does anyone else believe that the answer to the paradox is
simply that estimation errors have skyrocketed, and then plateaued
at exactly the same rate as cellphone ownership has?

Bicycling, here, is a hazardous activity -- despite being a "bike friendly"
community (we have large annual events). I've tried riding a bike *once*
in the 20 years, here and decided it was a foolish exercise. Too many
crazy drivers!

A neighbor once "threatened" to buy me a red shirt -- just because she
always saw me in black/navy or white. I'm not fond of bright colors
(and particularly hate *green*!) Given that I have complete control
over my appearance, I figure I should wear what I'm "happiest" with!
(if clothes can be said to make you "happy")
 
I've always adopted the "many of the same" approach. E.g., when I used
to wear dress shirts/slacks, I would have three or four of the same
shirt hanging side by side in the closet. So, it was not uncommon to see
me in the same "outfit" on successive days. Or, several times in a week.
 
Of course, it was typically the women who would notice such things
(I think all men check is whether or not you have clothes *on*!).
One lady commented once and I made a point of bringing in a handfull
of hangers with identical shirts hung on each: "Oh! I see..."
 
[Unfortunately, dark colors are bad for things like mosquitos; they
are *drawn* to darker colors]

Why would they? With automatic braking, lane detection, backup cameras
and the like other rates may be going down. You have to look at all the
numbers. Don't forget MADD too.

I haven't seen that episode, but I love the Mythbusters. I agree that
they probably don't "fudge" their data, but, I'm sure the *producers*
choose the most *interesting* data, and not necessarily the most
accurate results.
 
Still, I don't disbelieve that driving while using a cellphone is
distracting.
 
I just can't find any data that supports that the accident rate in
the USA is skyrocketing concomitantly with cellphone ownership rates.
 
So, while many individually contrived experiments easily show distraction,
why is it that there are no combined purely factual reports that
prove it's actually contributing to the accident rate in the USA?

Maybe. But if that were the case, wouldn't there have been an initial
spike in the accident rate, and then a tailing off of that spike as
we learned to avoid cellphone users?
 
No such spike in the accident rate seems to exist.

Wow. I use my cellphone every day, all day while driving. I must make
maybe a half dozen calls alone on my hour-long commute, and, on a long
drive, I'm on the phone almost the entire time. My problem is *power*,
as the phone heats up when GPS and phone calls are simultaneous.
 
Meanwhile, on long trips, the three kids in the back each have their
phones blaring some game or video (they never seem to find their
headpieces when we leave for long trips).
 
And, of course, the wife has to have her music playing on her iPod.
 
Meanwhile, I have had only one accident in my entire life, and that
was when someone rear ended me when I was in college, and it was partly
my fault because I decided to turnright without using a turn signal, but
braked hard for a yellow light (because the road suddenly came up
and I had not realized it was my turn).
 
That accident was clearly my fault, but the other guy got a ticket,
and when they called me into court, I told them exactly what happened,
and, they STILL upheld the other guy's ticket (which I thought was
kind of odd).
 
Anyway, I am shocked that you use the phone so little, as I use it
basically 100% of the time when I'm in my car.

No amount of *estimation* error is going to cancel out the huge
rates predicted by the reports.
 
Did you see the poster who showed a report of 25% greater accident rates?
 
Do you really believe that the "estimation errors" are exactly 1/4 of
the huge numbers, and then, that these estimation errors only occur
during the exact time frame when cellphone ownership rates skyrocketed?
 
And then, these very same "estimation errors" tailed off suddenly, and
precipitously, exactly when cellphone ownership rates tailed off?

I responded to that post of yours which assumes that the drunk-driving
campaign exactly cancels out the skyrocketing cellphone ownership
effect on accident rates, in both timing and in number.
 
It's far-fetched to believe that both the timing and the size of
the drunk-driving campaign results *exactly* cancel out that of the
cellphone driving effect, but it is one possible answer to the conundrum.

This is perhaps the sixth possible answer to the enigma.
 
If I understand your argument, it's that the laws on cellphone use while
driving have been 100% effective in preventing cellphone use while driving,
and that these laws are so effective as to cancel out totally the skyrocketing
accident rates predicted by the studies.

I've been asking for better accident rate data since this thread
started.
 
I'm not afraid of better data (you may be, but I am not).
 
> No more so than accidents.
 
You are missing a screw if you think that a second-order issue
such as injuries and fatalities will be simpler than a first-order
issue such as accidents (which are the cause of those injuries
and fatalities).
 
Are you seriously arguing that the injuries and fatalities would
have happened *without* the accident happening first?

The fact you used "lying" instead of "laying" tells me you are
intelligent; so I find it hard to believe you actually believe
that a second-order issue such as injuries and fatalities can
possibly provide the answer to the conundrum when the first order
issue itself doesn't provide that answer.
 
 
> You're just clouding an issue to make it seem like there's a paradox.
 
The paradox is so clear that the only ones 'clouded' by it are those
with an agenda that isn't supported by the data.
 
It's very clear:
1. Most of us (me included) believe that the skyrocketing ownership
of cellphones in the USA must mean a concomitant skyrocketing
*use* of those cellphones while driving; which itself, should
indicate a concomitant increase of driving-while-distracted cases.
 
2. Most of us (me included) have seen the scary studies which show
that the use of a cellphone while driving is distracting, and,
most of us (me included) conclude that driving while distracted
should be increasing the accident rate in the USA.
 
3. Yet, the best data shown here indicates that the accident rate
in the USA is not going up (in fact, it's going down).
 
Most of us would say that this is a paradox.
So far, six answers have been provided to satisfy that paradox.
 
> Deaths and injuries are directly though not necessarily linearly
> proportional to accidents.
 
You can't be serious if you want to use fatalities and injuries
as your justification while wholly ignoring the accidents that
*caused* those fatalities and injuries.
 
Fatalities and injuries have ten times the factors that the
accidents have - so - if accidents are too complex for you to
handle details about to support your arguments - there is no
way fatalities and injuries will support your argument.
 
The only person who would leap over accident rates to go to
fatalities and injuries, is a person who has cherry picked some
data which isn't supported by the accident rate, and wants to
stick with that cherry-picked data come hell or high water,
to support a bogus argument.
 
As I said many times, anyone with reliable accident rate data
is welcome to post it - as this thread is about accident rates,
pure and simple.

If a skyrocketing number of cellphone owners were to lay
their phones on the highway, as you did, would you expect
the number of crushed cellphones lying on the roadway to
suddenly skyrocket accordingly, concomitant with the
huge numbers of cellphones now lying on the roadway?
 
Wouldn't the timing and number of the cellphone crush
rate correspond to the number of cellphones laid onto
the highway?
 
If they don't - that would be a paradox to be resolved
as this one is.

You may be right. It's entirely possible that the texting
idiots with a coffee in the other hand merely scare the crap
out of us cyclists and don't actually connect all that
often, despite some spectacular lane drift episodes.

The ADC of this multimeter consists of the chipset of which I'm
searching for FEJ 271(B). Unfortunately, the manual/schematic which
can be downloaded from Elektrotanya is incomplete: the ADC section is
missing. Can someone of you help me finding/getting the complete
manual/schematic? Many TIA!

there was an early ADC chipset manufactured by Mullard consisting of
FEY101, FEJ271 and 74141 ic's. While FEY101 is still available
FEJ271B seems to be unobtainium. Can someone here help me to get one
or two pieces? Many thanks in advance for your help.

That brings up a good question which I didn't know the answer to.
 
Being a cheapskate, I bought my coax cable from the Goodwill for a buck.
 
I know there are different impedances for coax cable, but I didn't know
what letting to look for on the Goodwill coax cables.
 
So, the one I bought said "CATV" but I don't know if that's the right
cable.
 
Is it?

We should probably list the various servers.
I'll make a start, but this is just from memory.
 
1. speedtest.net
2. speedtest.comcast.net
3. speakeasy.net/speedtest

I wonder if Jeff knows whether it's best to use the speed test supplied
by the ISP, since that's most likely to follow the same pipes?
 
That is, if I'm using AT&T, wouldn't the most accurate speed test be
one that AT&T supplies, which uses AT&T pipes?
 
Likewise, for comcast?
