A Caution
Just remember…we might replace the RINO candidates. (Or we might not. The record is mixed even though there is more MAGA than there used to be.) But that will make no difference in the long run if the party officials, basically the Rhonna McDaniels (or however that’s spelled–I suspect it’s RINO), don’t get replaced.
State party chairs, vice chairs, secretaries and so on, and the same at county levels, have huge influence on who ultimately gets nominated, and if these party wheelhorses are RINOs, they will work tirelessly to put their own pukey people on the ballot. In fact I’d not be surprised if some of our “MAGA” candidates are in fact, RINO plants, encouraged to run by the RINO party leadership when they realized that Lyn Cheney (and her ilk) were hopelessly compromised as effective candidates. The best way for them to deal with the opposition, of course, is to run it themselves.
Running good candidates is only HALF of the battle!
SPECIAL SECTION: Message For Our “Friends” In The Middle Kingdom
I normally save this for near the end, but…basically…up your shit-kicking barbarian asses. Yes, barbarian! It took a bunch of sailors in Western Asia to invent a real alphabet instead of badly drawn cartoons to write with. So much for your “civilization.”
Yeah, the WORLD noticed you had to borrow the Latin alphabet to make Pinyin. Like with every other idea you had to steal from us “Foreign Devils” since you rammed your heads up your asses five centuries ago, you sure managed to bastardize it badly in the process.
Have you stopped eating bats yet? Are you shit-kickers still sleeping with farm animals?
Or maybe even just had the slightest inkling of treating lives as something you don’t just casually dispose of?
中国是个混蛋 !!!
Zhōngguò shì gè hùndàn !!!
China is asshoe !!!
And here’s my response to barbarian “asshoes” like you:
OK, with that rant out of my system…
Biden Gives Us Too Much Credit
…we can move on to the next one.
Apparently Biden (or his puppeteer) has decided we’re to blame for all of the fail in the United States today.
Sorry to disappoint you Joe (or whoever), but you managed to do that all on your own; not only that, you wouldn’t let us NOT give you the chance because you insisted on cheating your way into power.
Yep, you-all are incompetent, and so proud of it you expect our applause for your sincerity. Fuck that!!
It wouldn’t be so bad, but you insist that everyone else have to share in your misery. Nope, can’t have anyone get out from under it. Somehow your grand vision only works if every single other person on earth is forced to go along. So much as ONE PERSON not going along is enough to make it all fail, apparently.
In engineering school we’re taught that a design that has seven to eight billion single points of failure…sucks.
Actually, we weren’t taught that. Because it would never have occurred to the professors to use such a ridiculous example.
Justice Must Be Done.
The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system.

OK now for the fine print.
This is the WQTH Daily Thread. You know the drill. There’s no Poltical correctness, but civility is a requirement. There are Important Guidelines, here, with an addendum on 20191110.
We have a new board – called The U Tree – where people can take each other to the woodshed without fear of censorship or moderation.
And remember Wheatie’s Rules:
1. No food fights
2. No running with scissors.
3. If you bring snacks, bring enough for everyone.
4. Zeroth rule of gun safety: Don’t let the government get your guns.
5. Rule one of gun safety: The gun is always loaded.
5a. If you actually want the gun to be loaded, like because you’re checking out a bump in the night, then it’s empty.
6. Rule two of gun safety: Never point the gun at anything you’re not willing to destroy.
7. Rule three: Keep your finger off the trigger until ready to fire.
8. Rule the fourth: Be sure of your target and what is behind it.

Pi…or π if Greek Floats Your Trireme
I probably should have done π before doing e. It’s a lot more relatable for most people, who find compound interest magical…and if they don’t find that magical, the idea of continuously compounding it might induce a headache if they think about it too much. (The way out involves concepts verging on calculus.)
But who the heck can’t visualize a circle?
Pi is, of course, the ratio of the circumference of a perfect circle, to its diameter.
The ancients wrestled with this. Pi isn’t quite 3. Nor is it 22/7ths (or 3 1/7 if you can’t stand so-called “improper” fractions and have to see it as a “mixed number” [an integer plus a “proper” fraction]). [An “improper” fraction is any fraction where the top number is at least as large as the bottom number, e.g., 22/7 or even 5/5.]
Perhaps they just needed a different fraction. 333/105 is closer to π, 355/113 is closer still…but neither are spot on. Nor are 52163/16604, 103993/33102, 104348/33215 nor even 245850922/78256779.
There is no possible fraction with integers top and bottom (numerator and denominator) that will represent π. It cannot be expressed as the ratio of two whole numbers. It is ir-ratio-nal. Which leads to “irrational” numbers being a term. It’s unfortunate, because it makes them sound crazy, woke, Leftist, or something.
However, if you truly want a crazy number, consider either the number of illegal “immigrants” coming through…or the US Federal debt.
Pi works out to 3.14159265358……approximately.
There are plenty of irrational numbers out there. For example, if a number isn’t a perfect square (e.g., 1, 4 (2×2), 9 (3×3), 100 (10×10), or 3721 (61×61), then the square root of that number is irrational. So the square root of 3 is 1.732050807…. (easy to remember the start of this, as George Washingon was born in 1732 (new style)).
An irrational number can’t be written as a fraction, and if written as a decimal never ends.
But wait, 1/3, when written as a decimal never ends, either. And 1/3 is clearly a ratio-nal (rational) number.
But a rational number written as a decimal will fall into a repeating pattern if it doesn’t actually end. 1/3 = 0.33333…. (obvious repeat), 1.6 = 0.166666 (repeats, after the first digit). 1/7th = 0.142857142857…. (a seven digit group, repeating forever). In fact the maximum number of digits before repeating is the denominator itself minus 1; 1/7th is at that maximum since it repeats after 7-1=6 digits. So does 2/7, 3/7 and so on (in fact the repeating digits form the same sequence, just started in different places. 5/7= 0.714285714285…. In fact fractions n/7 start with every single one of the numbers in the sequence ending with 6/7=0.857142857142.
[This repeating nature of some fractions…but not 1/2, 1/4, 1/5, 1/8, 1/10, 1/16, 1/20 and so on, is an artifact of our decimal system, operating in base 10; 10 expressed as the product of primes is 5 x 2. As a result, if the denominator is a number that factors completely into 2s and 5s (i.e., any number of 2s and any number of 5s, in any combination), the decimal point representation will eventually end. But if the prime factors of the denomination include any other number…the decimal will never end, but will repeat. So, for instance, 60 (2 x 2 x 3 x 5) has that one 3 in it, so fractions with sixty in the denominator may not end. They will end if the numerator also divides by 3; then the 3s cancel out, e.g., 42/60s also equals 14/20ths or 7/10ths. The denominator is only 5s and 2s and so that fraction is just 0.7.]
So e and π are both irrational numbers, along with almost every square root, cube root, fourth root, and so on.
But π and e are also members of a class known as transcendental numbers. These are numbers that are irrational and can’t be found by solving a polynomial (which can involve taking a root of some other number). In other words, you cannot write a formula like this:
xn – m = 0
Where m and n are any integers you care to pick, and have x equal to π or e or any other transcendental number, whereas the square root of 2, which is also an irrational number, isn’t transcendental because it solves this problem with m and n both set to 2:
x2 – 2 = 0
(By the way that’s true even if you combine different powers of x; I just gave a simple case.)
Pi can now be computed to billions of digits, and there’s no sign of it ever ending (nor is it expected; it has been proved to be transcendental, and in math you can actually prove things to be solidly, incontrovertibly true).
Pi is hugely important in mathematics; it shows up all over the place. And in the sciences just about anything having to do with geometry will have π in it. It shows up in Maxwell’s equations and in Einstein’s equation describing general relativity, both of which involve geometry.
Pi also shows up in measuring angles. Consider a circle of radius 1. (We don’t care about whether that’s a meter, furlong, line, chain, light year, or parsec, though the last two would be a bit unwieldy in a diagram.)
Now imagine starting at the right side of the circle (3 o’clock), and going counterclockwise, measuring the length of the arc. If you go all the way around the circle, your total length is 2π. (Remember the radius is 1, not the diameter.) Since this is based on the radius of the circle, we say you have measured an angle of 2π radians. And this works as an angle (not a linear measurement) because it doesn’t matter what the size of the circle is; the full trip around the circumference is of course 2π times the radius, a full circle is 2π radians as well as being 360 degrees.
This sounds like it should be a solid pain in the butt. A 30 degree angle is 1/12th of the full circle, so that works out to π/6 radians or 0.5235987755982987307710723054658…radians. Most people would give up sooner than I did. But who wants to write that out even to five digits?
So they don’t. They’ll write that angle as π/6.
Since radians are simply one length divided by another, without any sort of constant fudge factor thrown in, they’re dimensionless (in physics) and for mathematicians are the “natural” way of working with angles, just like e is the natural base of logarithms.
OK, so how about, instead of stopping after traveling around the full circle, you stop after some other, arbitrary angle? Where are you? You start at one unit to the right and zero units up. After a quarter circle (π/2 radians), you’re now at zero units to the right, and one unit up.
How about that thirty degree angle? Which is to say, 1/12th of the way around the circle, which is to say π/6 radians? Well it turns out you are 1/2 a unit up (exactly), but the square root of 3, divided by 2 a/k/a sqrt(3)/2 units to the right. So yes most of the places on a circle have coordinates that are irrational (but not necessarily transcendental) numbers. Some few places have “special” coordinates, like 45 degrees (π/4 radians), where both sine and cosine are the square root of 2, divided by 2 or sqrt(2)/2; most are just some irrational number you can’t relate to the square root of some nice tidy little number like 2 or 3.
You can conceive of a function that will tell you how many units to the right you will be for any given angle…and another that will tell you how many units up you are for any given angle. You could even give these functions names, like, oh, say…cosine and sine.
Of course, I didn’t just pull those names out of my rectal database. Those are the actual names, and they get abbreviated cos and sin. (So somebody else pulled those names out of his rectal database, and managed to get everyone else to go along with it.)
It seems like this is a contrived situation, but this is astoundingly useful. First objection: Not all circles have a radius of 1. In fact most of them don’t.
So what? It scales. If a circle has radius 1.945, you can compute those positions by simply multiplying the sin and cosine of whatever angle, by 1.945.
[Or you can look at it another way…all circles have a radius of 1…provided you can pick whatever measuring system you want!]
So you will see sines and cosines all over the place in physics; just for instance the way you break a vector up into its components uses the sine and cosine of the angle the vector is pointing towards. A vector of length 10 pointing off at a 60 degree…ahem, π/3 radians) angle will have an x component of 5 (i.e., 10cos(π/3)) and a y component of 10 sqrt(3)/2 (i.e., 10 sin(π/3)). (Note that the cosine and sine of 60 degrees are swapped from the cosine and sine of 30 degrees.)
So sine and cosine can be very useful. And mathematically speaking, if you just take the cosine of some number…that number is assumed to be in radians. (Even deep in the bowels of your computer, in the arithmetic coprocessor, the sine function will take radians as its parameter. What you see on your spreadsheet when you ask for sin(30) is computed only after turning 30 degrees into radians.
And again radians are the natural way to do this. So much so that when taking about, say, the sine of some number, mathematicians don’t even bother to specify “radians” because a radian is simply a dimensionless ratio of arclength to radius without a fudge factor in it, like there would be for degrees.
Now there’s one more thing, and I will give my fingers (and your brains) a rest. The names cosine and sine imply a connection between the two functions, one is the co– of the other.
And that’s true. Let’s switch to degrees for a moment and check a few key values. The cosine of zero is 1. The cosine of 90 is 0. The cosine of 180 is -1. The cosine of 270 is 0 again. And the cosine of 360 is 1 again. And you can fill in the halves, the northeast, northwest, southwest and southeast: The cosine of 45 is sqrt(2)/2, the cosine of 135 is -sqrt(2)/2; the cosine of 225 is again -sqrt(2)/2, and the cosine of 315 is sqrt(2)/2. Merging the two sequences, and writing them out in order: 1, sqrt(2)/2, 0, -sqrt(2)/2, -1, -sqrt(2)/2, 0, sqrt(2)/2 and back to 1, after which 405 degrees is basically the same as 45 degrees, so we repeat the same cycle, over and over again.
Now let’s do the same thing for sines. We get: 0, sqrt(2)/2, 1, sqrt(2)/2, 0, -sqrt(2)/2, -1, -sqrt(2)/2, and back to 0.
Note that they are the same sequence…just starting at different places. If you were to actually graph these functions, they’d look identical…just one would be shifted compared to the other. So there’s definitely a connection worthy of deeming one of them to be the co– of the other.
The sine and cosine are important concepts, and although you can learn to play all kinds of tricks with them–enough so to be worthy of a full semester of math class–really what you’re going to need if you haven’t already rage-quit reading my posts, is to remember that the cosine is the distance to the right of zero (so it’s negative if you’re to the left of zero), and the sine is the distance above zero (so it’s negative if you’re below it), of a point on the “unit circle” (radius 1).
[And yes, being to the left of 0 as in 0bama is pretty far left.]
One last note. The full circumference of a circle is 2π. And because of that, a lot of formulae in physics have a 2π in them. So much so that some argue that the more natural constant is the one we think of as 2π, the ratio of the circumference of a circle to its radius rather than its diameter. That, of course would be 6.283…rather than 3.1415926…and those who make this argument advocate for calling this number τ, i.e., the Greek letter tau. (It rhymes with how.) This position is becoming increasingly popular but I doubt it will ever supplant pi. On the other hand, it’s natural to talk of τ/4 radians and have that be a quarter circle (rather than half of a half circle); that’s more intuitively a right angle than π/2 is.
OK, so far we’ve discussed numbers that show up on a number line. They may be transcendental, impossible to write out in full even as a fraction, but you can say that e is between 2.71828 and 2.71829, and that π is between 3.1415926 and 3.1415927.
Our next number, however, will be one you cannot do that with.
