Fucking, Heisenberg. It's always science or cheap Chinese vises with this bitch. :>)

I did what you asked me to do, Heisenberg and took the fucking quiz. Here are my results copied and pasted:

"Science and Technology Knowledge Quiz Results

You answered 12 of 13 questions correctly."

Here is the question I missed:

"Which gas makes up most of the Earth’s atmosphere?

You answered "Hydrogen"

The correct answer is "Nitrogen"

I feel like an idiot for missing this question, Heisenberg. There goes my "A-1 day". I hope you're happy.

I'm sure you got everything right.

Worse. It proves the "dumbing-down" of US education.

THIS is the crap that our Bastions of Science are offering up as a
reasonable test of "Scientific Knowlege"!

If any adult or child over the age of 13 doesn't know - to the CORE of
their being - every one of these things, then they have the mental
capacity of a gopher tortoise -- or their "teachures" do.

As others have correctly pointed out, Heisenberg it's a lame test that only shows how dumb America has gotten. Anyone who doesn't know the answer to any of these questions should be ashamed of themselves like I am for missing the question I missed.

Gotta love the FACT that Mark Wieber clique idiot Larry Jackass claims to have gotten 13 out of 13 but can't even quote Thomas Jefferson correctly:

Lloyd:

I don't think this little quiz was meant as a reasonable test of scientific knowledge. Here is my response after being forwarded this "gem" of a quiz:

=====================================================
I'm Shocked & Dismayed!!! Don't want to seem judgmental or anything... but I'm APPALLED at the poor showing of their random sample. At first I thought their "random" sample was taken from the Ozarks or Appalachia where kids never went to school or learned how to read. This is a major indictment against the results of our education system.
I especially was disappointed at the low percentage of correct answers in MY age group (65+), were they polling Alzheimer's patients?
No wonder America is in the mess it's in. Every Congress Critter should be required to take this test, and if they miss more than two questions they should be impeached and stripped of their position due to mental incompetence.

OK, ok, let me climb down off my soapbox. I still am having a hard time believing it though. Perhaps their results were fabrications just to gauge other people's reactions? Sure got a reaction out of me.
=====================================================

Back to real-time here. This quiz has generated enough passion in me to post it here to RCM. That's probably the first thread I've started in a couple of years.

What the listing of your answer, and the correction, will probably do is remind the people that may have forgotten, just what they learned in High School science class so many years ago. No overt cheating would necessarily be involved. But what this "reminder" may do, is skew the results from your post forward.

That was essentially the primary reason for me posting it in the first place. That, and the opportunity for all us metal-heads to compare our science knowledge to that of the average citizen.

Got that one wrong. Without googling, I mixed plasmids up with
prions. I'm not keeping up on my biochemistry. :-(

I did a term paper on mitochondria in '61. At that time. The notion
that mitochondria originated as endosymbionts had been raised but was
roundly ridiculed. It began to get some traction in the 70s but even
then, a biochemist friend still ridiculed it. Not so much now, albeit
still undecided.

What shocked me about the OP's quiz was that only 31% or college grads
got the atmosphere composition right. Then I relfected on all the
grads I know who took the absolute minimum number of science credits
required for their degrees in economics or English or education. But
it's still a pathetic number.

You answered 13 of 13 questions correctly.

======================================================================

While not stating which question, I was amazed at how few people
got one in particular right -- the overall balance was 20% and even the
college graduates only got 31%. I thought that one was common
knowledge. :-)

Hmmm, that might go a long way toward explaining why there is so much controversy over Global Warming in the general population.

Common courtesy doesn't exist on Usenet.

"If someone has to cheat and not be honest with the question I missed or if they pretend to know the the answer I revealed, they are going to lie and cheat anyway."

Hence it doesn't matter that I admitted my mistake and said what it was.

Let me try to explain it a different way. People assimilate new information and compare/contrast it to prior information constantly and almost subconsciously.
Reading of your mistake, and the correct answer, might not even register consciously. But when taking the test they might tend to go with what "feels" like the correct answer. Not even being aware of having read your post.
And being as that particular question appears to be the one that is missed most often... it can skew the results.

It's not an opinion it's a fact. Feelings have nothing to do with it.

"And being as that particular question appears to be the one that is missed most often... it can skew the results."

Rather than pat ourselves on the back for getting perfect or near perfect scores it would make a lot more sense to do what you did and ask why do so many miss this question. My answer is that it's not emphasized enough in school like other topics are.

"Metalworking topics may be on life support, but IMO given a little nurturing I think they could be revived."

Not a chance. Usenet doesn't attract the needed newbies with an interest in home shop CNC machining and CADCAM. That's now all gone to advertising driven forums. One day that will change and there will be advertising free groups that will be started and run by home shop machinists, probably using a network much like LinkedIn has created for professionals.

LinkedIn is now where all the best professional CNC machining and CADCAM discussion happens.

Let's take a closer look at this. You said: "Common courtesy

in Usenet would have to continuously act in an uncivil
or discourteous manner. That doesn't happen since innumerable
examples of courteousness & civility exist. So your statement is NOT
describing a universal & unwavering condition of Usenet. It's an
interpretation from your own perspective... IOW your opinion.

I believe you're correct in that assessment. Many people think "oxygen" is synonymous with "air", since everyone knows our bodies need oxygen to

I think you forget that RCM is a HOBBY metalworking group (and not

a professional CNC machining CAD/CAM group such as AMC was.

I think it would have been safe to say that ten years ago. Today... I'm
not so sure it wouldn't be better worded "A minority of 'Home Shops'...".

Advertising, cheap low-end stepper-driven machines from China, and ARM
processors have made the entire category of CNC more common and more
affordable.

Now... 'Home Shops' that have big CNC iron are fewer, to be sure! But
even that's becoming more common as conversions become simpler and less

Not to drag this too far off topic (as if it wasn't already), being able to express your agreement or appreciation for someone else's writing without writing an extended comment yourself isn't necessarily and "easy out." It can be, on the other hand, a very succinct and economical way of communicating your opinion.

On the other hand, you may be one of those who believe that there are no yes/no questions, and everything is an essay question. Can you imagine the process if every vote taken, from the passing of bills in Congress to the November elections to ordering at McDonalds required a written opinion? Sometimes it's just better to click a button to cast your vote.

In my college days the liberal arts majors used Astronomy for the easy
passing grade.

Then again, I took Theatre to satisfy the Humanities requirement
because the prof never assigned written homework (to actors and
dancers???) and accepted any lame BS we came up with ("artistic
freedom") when called on in class. Theatre is about how misfits abuse
those they envy which you should know from kindergarten, or the
political rants here.

There was also the eye candy factor.

For scheduling reasons I took Statistics in the Liberal Arts
department. That was another no-study passing grade for the
math-impaired, but I was too far along when I realized it wasn't going
to be very useful. And the explanations of the many ways to rig a
"random" survey were interesting. One was to call homes during working
hours, which overly weights the responses with the retired and
unemployed.

It's quite disconcerting to pollsters that I can mentally calculate
the error margin for their sample size while talking to them, even
more so if they know it's the reciprocal of a square root.

There was an order of magnitude's difference between the intellectual
demands in the Engineering and Liberal Arts curricula. A science
degree proved that you could comprehend and extend what you'd learned,
a liberal arts one that you could memorize.

I only got 90 but I think the creator of the test didn't do any better.

On the gears, if it's a gear drive, it's not a direct drive, and the two
equal size gears, one gear is rotating reverse from the other. All reverse
rotation except the one with 3 gears. So there was reverse and reduction,
reverse and overdrive, reverse, and reduction without reverse.

On the pulleys, there was a direct lift, pulley with force at right angle,
and pulley with force down, unless you have miracle pulleys with zero
friction, the direct lift takes less force. I ignored the friction of the
pulleys and weight of the rope and picked the answer they wanted.

On other pulley's they showed the force with the rope at an angle, not
straight vertical. Their answer they were looking for was only correct with
a straight vertical pull with no horizontal component.

I missed one because I didn't enlarge the image and thought the lever was
being lifted by the wrong end, I thought the fulcrum was an arrow showing
lifting up.

I used a ProtoTrak Bridgeport to modify Segway castings for
experiments and found that I liked the old manual layout and nachining
methods better. There was no flat surface to establish an X or Y zero
and the drawing referenced "See the pattern" for much of the detail,
like the battery mounting bosses. The slew knob wasn't nearly as
ergonomic as table handwheels. For poorly defined one-time jobs not
that different from the custom-fitted tools and repair parts I make at
home it was less convenient than a manual mill.

When I had to drill mounting holes for a circuit board made on a CAD
system I printed a listing of the hole coordinates and drilled them by
the DRO since the circuit board Excellon drill file format was
incompatible.

There are about 4 that are a bit ambiguous - where you (and I) likely
outhought ourselves. One was the gear ratio question where several
were reversed - overdrive and reduction, as well as direct, and only
ONE was a non-reversing ratio (a reduction). Otherwise a much better
test than the science one. The pulley one likely got me
too.(multi-sheave)

That tested if you had ever rebuilt a manual transmission rather than
general gear theory, because of the implicit reversal of rotation in
forward gears.

I get into trouble on tests like that when I see variables where they
assumed constants, like the thickness of the balloon rubber.

I was a "hobby guy" when I bought my first CNC mill... an old, NOT worn,
but electronically broke R2E4.

That was an epiphany for me. I had a full-up commercial/industrial
machine, WORKING (after a few tens of hours of troubleshooting) for under
$3000. That cost included the purchase price, the transport 120 miles to
my shop, the wrecker to boom it off the trailer, and the repairs.

I think I spent more on original paper manuals and tooling than I did on
the machine itself. And it's a 'keeper', especially since the lightning
hit that required a retrofit to CentroidCNC. It's now faster, more
accurate, and reliable!

Too bad there aren't a lot of "hobby" well drillers. A local driller
was closed down by the bank last week - brand new 1.7 million dollar
drill rig which had only dug one hole went for just about $500grand..
I wasn't there or I could have picked up a 2010 Ford escape in prime
condition for $3500 - the pickups all went for under $2500 (newest was
2010 with about 35000 miles on it) and 8 brand new office furniture
sets (modular l shaped high end wood grain, with bookshelves etc -with
office chairs - complete - less than 3 months old, went for TWENTY
FIVE BUCKS - for all 8!!!!

I have (and use) a small CNC lathe (The Emco-Maier
Compact-5/CNC). I also have a Bridgeport which started live as a
stepper-based CNC, which I was converting to servo motors, before a fire
set me back a ways. I'll get back to that as time goes on.

Well ... I've gotten a lot of use out of the little
Compact-5/CNC, even though it is rather slow. Among other things, it is
the easiest way *I* have to cut metric threads at present. The 12x24"
Clausing manual machine has a set of transposition gears, but is a real
pain, because the half-nuts need to be kept closed from the start of the
thread until it is complete.

But some other things which I started doing on the little CNC
lathe turned out to be a lot quicker on the Clausing, using a bed
turret, and Geometric die head among other things.

Enjoy,
DoN.

Friend/classmate bought a Cincinnati #1 vertical mill. Cost him
more to ship it than to buy it, much less than two grand total. Got
it set up and discovered that it had a swivel table (brain fart, can't
recall the technical name for such a thing - the entire worktable
pivoted) as an added bonus.

He was happy.

460 points -- 92% -- with the problem that it is showing up too
small on my screen, and I got a sound (only) when making one submission.
I'm not sure whether I got that wrong, or just mis-checked.

Depends. I got a "you are not allowed to visit this page" after
clicking to get the scores.

And there was one question (I guess that I should not say
anything else about it) for which I could see only answers that I
considered wrong, so I selected the one which I considered least wrong. :-)

That last one mentioned is I think what I got wrong, and *none*
of the answers for that one looked right to me. At least, that one
offered the ability to click to enlarge the pulley part, though it left
off the weight on the bottom, and I was having difficulty reading the
weight value, too. :-) (One of the problems of having a high-resolution
screen. And the web page would not let me click to increase the
magnification. :-(

And that one was ambiguous, too. Are they asking whether the
two fans, as they sit, are rotating the same or opposite directions as
viewed from one fixed point, or as compared to the normal running
direction?

Mine is yellow -- though later ones were gray or red (or
perhaps a combination of the two).

It could have been a lot faster with a better choice of CPU. It
runs from a 6502 (what was used in the Apple ][ and the Commodore Pet
among other home computers. In particular, while it has Carbide inserts
for many things including threading, it is necessary to slow the spindle
speed down to about 200 RPM or lower for moderately coarse threading such
as 20 TPI or 1 mm pitch. Leave the spindle speed faster, and it
displays an error message on the CRT (if present -- that is an option),
and some error number on the LED readout display. Turn down the
spindle speed, and it starts threading. The spindle has an index plate
to show it where it is in its rotation, and the lathe has to compute
at which index hole it makes its next step. (And, it does everything
internally in metric units, though it will accept commands in inch
units. And it is a little more precise in metric units. Steps of
0.01mm or 0.002" and when stepping manually in inch mode. sometimes it
is two ticks before the next figure displays, sometimes one.

And the program format is insanely picky. Decimal point
location is implied, not displayed. and if you lose a space out of a
line of code, everything is multipled by 10 because of the position.
Here is what the start of a program looks like:

======================================================================
%
N` G` X ` Z ` F` H
00 90
01 92 1904 00
02M03
03 84 1900 - 5000 15 00
04 84 1650 - 1000 10 05
05 01 1850 - 1000 10
06 25 L 22
======================================================================

and the end:

======================================================================
21M30
22 01 1900 - 4832 10
23 00 1900 - 1000
24M17
M
======================================================================
The 'M' standing alone on the last line tells it that the program is in
metric units. Inch units have a '"' there instead.

Indeed. And several of the others in the local metalworking
club have modified small lathes or desktop mills to be CNC as well.

Don:

Since it cuts better in metric... have you tried to cut inch threads in their metric equivalent? Like 20 Threads Per Inch = an inch pitch of .050 OR a metric pitch of 1.27mm.

Here's a site with a list of pitch conversions to metric.

Heh, yeah. If memory serves, that's the old NC "Full Address" format. Sometimes they had following zero suppression, and sometimes leading zero suppression. Just be glad you don't have to use a Flexiwriter and punch your programs out on paper tape and THEN take the tape over to your machine and feed it into your tape reader. Ahh the good ol' days... Just kidding, those days were miserable compared to modern machines and CAM systems that do all the grunt work for you.

Thanks. Says I got 96. The pop window was a bit big for my

Whenever I want serious accuracy (at least, as serious as it can
provide), I do convert to metric, and program it in that mode.

As for the "as serious as it can provide" part -- among other
things, while the maximum resolution is 0.01mm (or 0.001"), when
turning, that it the radius value, so the diameter goes in steps of
0.02mm or 0.002" (plus or minus conversion limits in the inch mode. :-)

I just always keep a HP 15C calculator handy, and do the
conversions on the spot.

So -- it has a name other than proprietary to EMCO-MAIER. :-)

Leading zero here -- but if you don't have the zero, you better
have the space to take its place. :-)

Well ... I used to have (and use) a Friden Flexowriter. And
among other things, it did not use ASCII (which the Compact-5/CNC does,
at least.) I used it on my first home computer as the output half of
the console. I had to write MC6800 assembly code to convert ASCII to
the nearest equivalent in the Flexowriter's character set.

What that code *is*, apparently, is a BCD implementation of the
EBCDIC code used on some mainframes. Except that it was also an
electric typewriter, which had shift-up and shift-down codes to select
upper or lower case. Great fun driving that thing. I had to send it a
sequence on "boot" (power-on -- no OS to boot) to make sure that it was
in a known state. That was my first serious programming project, to
allow me to use the computer for other things (until I finally got an
ADM-3A terminal in kit form. The computer was an Altair 680b, FWIW, and
I still have it.

And some Flexowriters used a 6-level tape, instead of the
8-level that the one I had used.

Oh yes -- while it does not *use* ASCII, it could (and did)
duplicate punched tapes in ASCII -- I used it to make several copies of
the BASIC interpreter tape -- and finally punched a Mylar tape which did
not wear out like the others. But it *did* nearly burn out that punch. :-)

But doing that work in assembly language (and having to hand
assemble it at that) certainly taught me a lot about the inner workings
of computers. The sort of thing that you are "protected" from these
days. :-)
