I'm predicting a spring drought

We had record rainfall in 2018 (and only 3 dry weeks in the Summer), and it hasn't slowed since. The Pendulum must swing, someday. Glad I'm not a farmer and there's floor drain in the cellar.

Shouting Thomas said...

No, it's a prediction of things to come.

I suggest you take it seriously.

Shouting Thomas said...

Bob Hope, 1975: “I’ve just flown in from California, where they’ve made homosexuality legal. I thought I’d get out before they make it compulsory.”

No spring yet in Beantown, though the day is lengthening nicely and the sun is higher in the sky.

Why are sewer, and manhole, covers round?

That question was the first on an end of term math exam my senior year in high school. Few of us gave the correct answer.

Have a good day, outside, wherever you are.

Curious George said...

"Why are sewer, and manhole, covers round?"

So they can't fall through.

Humperdink said...

So I just delivered a truckload of my ash logs to the local Louisville Slugger baseball bat mill. I had to cut the ash trees down so as to beat infestation from the emerald ash borer beetle.

The plant mills them into round blanks and then sends them off to the finishing plant, presumable to Louisville.

Every home run hit this year I am going to attribute to my trees. Well, maybe not all.

MadisonMan said...

but I'm predicting a spring drought for the upper midwest

What does that mean? Half of normal rainfall? 1/3rd? What do you define as Upper Midwest? WI/MN/MI?

The Climate Prediction Center (which did terribly for this past winter, but ...) doesn't have much of a prediction for here in April/May/June. Wetter and warmer just south of here though.

MadisonMan said...

That's really cool! Do they have to dry the wood out first before making the bats?

Ralph L said...

I can think of several reasons, but most likely because the lid can't fall through.

Meade said...

"What does that mean? Half of normal rainfall? 1/3rd? What do you define as Upper Midwest? WI/MN/MI?"

It means dry, buff singletrack whenever I'm in Copper Harbor, Southern Kettle Moraine, or Brown County Indiana. :)

We had to destroy the village in order to save it.

It looks like Althouse has blurred the street sign, in order to keep her acolytes from flocking to her door for a heaping helping of cruel neutrality.

Ralph L said...

We may have used the exact same words, but I swear I hadn't read Curious George's much quicker answer.

cronus titan said...

Looks like someone took an ice pick o that sign. Are you guys the drug runners in Madison? Or is the street named after a white person and the students rioted against the sign?

rehajm said...

That's some quality snrit. Mabye a little snit mixed in there, too if the dogs walk by that drain...

rehajm said...

Can you tell me how to get, how to get to (NAME REDACTED) Street?

Josephbleau said...

If you drop a non round manhole cover on your foot with the corner down the stress concentration will cut into your bones, unlike a round one, which would merely mash you.

rehajm said...

Round manhole covers are easier to move.

Big Mike said...

@Meade, looks like you did a good job. Did your lady love make you a cup of hot chocolate when you were through?

tcrosse said...

Round manhole covers fit round manholes.

Hagar said...

The most likely reason is that manhole covers come in matched frame and cover sets, both made with cast iron, a brittle material.

"Can't fall through" is silly. The cover rests on a sill within in the frame and the edge of the cover to frame surfaces are also cast slightly conical, so that the cover can be lifted off when access is needed.

Josephbleau said...

Hagar the square root of two is greater than 1. It will fall thru.

tim in vermont said...

Thank God I am not a north country snowed in resident.

I miss it, thinking of moving back.

Hagar said...

And yes, also because round manhole walls mean the walls are subjected to uniform compression all around and is easily tapered in at the top to allow for the minimum access hole diameter required for a man to enter and exit.

Humperdink said...

"That's really cool! Do they have to dry the wood out first before making the bats?"

Josephbleau said...

A 1 foot square plate will pass thru a 1 foot square hole if you hold it vertically and pass thru on the diagonal, right?

Humperdink said...

"A 1 foot square plate will pass thru a 1 foot square hole if you hold it vertically and pass thru on the diagonal, right?"

Yes it will, but a large manhole rat stuck in one of the vent holes makes it difficult.

Hagar said...

Yes, and the idiot who does that can also be sent down the manhole to fish it back out and put in place properly.

Actually, you have a strong point, but the structural considerations are the more important.

Big Mike said...

Since the corner to corner diagonal is longer than the side to opposite side for any regular polygon with an even number of sides, a polygonal manhole cover held on its side can be twisted so that it can fall through the opening. As the number of sides goes up, the difference between the corner to corner measure and side to opposite side measure goes down, until one gets to a circle, which can be thought of as a regular polygon with an infinite number of sides, and the difference goes to zero.

Note that if the number of sides is odd (and greater than 3) then the argument is only slightly more complex — directly opposite a corner is a side and there are two corners (not quite directly) opposite any corner.

Hagar said...

PhD.

gilbar said...

None of which changes the facts that:
A) manhole covers are SO HEAVY that it's VERY UNLIKELY you would 'unintentionally' lift one vertical
B) pipes are made round for completely other reasons; seems very likely (to me) that any 'can't drop through the hole'ness is gravy ("how the HELL are we supposed to get these covers down the hole? It's not a bug, it's a feature!")

There's no wrong way to put a round manhole cover into a round manhole, except upside down.

When I was young, the city seemed to make some effort to make the manholes the same elevation as the rest of the street. That kind of quality control is long gone, and now they are either recessed so far you can throw a hubcap, or hiked up so far that it's like running into a curb.

Shouting Thomas said...

Actually, homophobia is that voice in a gay’s head telling him his parents want grandchildren.

Shouting Thomas said...

In other words, like sexism, homophobia is a nonsense term.

Nobody’s really afraid of women or hates women.

Nobody’s really afraid of gays or hates them.

Those are terms of Marxist construction designed for the political purpose of shutting people up.

There is no reality to either term.

It’s all bullshit.

Shouting Thomas said...

Since I lived in San Francisco as the AIDS epidemic broke out of the bathhouses, and in NYC during the days when the great die-off transpired, I assure you that I thank God that I didn’t want to fuck men.

I watched dozens of friends and fellow artists die shitting themselves to death.

This did not inspire sexual cravings in me. Had Howard been correct about me, I would have long since been dead.

It’s interesting, however, that Howard the Dummy plays the game of homophobic taunting while complaining about homophobia.

Howard the Dummy is one mixed up dunce.

Shouting Thomas said...

Inga, on the other hand, really has no political views and ideals.

She’s just a vengeful, vicious, idle and pathetic women with nothing to do but to ponder her various vendettas.

So if two similar cars, similar speeds, are racing down the highway going in opposite directions and they collide head-on, their combined velocity will be twice as much?

The fact is that a great many things in this real, physical world of ours do not (naively) obey the 1 + 1 = 2 rule. In this particular case, the rule is more like 1 + 1 = 0!

Problems like this are why physicists have invented more complex entities than just simple, so-called “scalar” numbers — such as (e.g.) complex numbers and vectors — to describe real-world phenomena.

The lesson, basically, for most real problems is that 1 + 1 ≠ 2.

Quaestor said...

Notice that Michael McNeil does not confuse speed with velocity. Speed has only magnitude, much like Howard's ass.

Michael McNeil said...

Gilbar: Who says some velocities should be ‘–’ and some ‘+’ and what's the rule to do so? In fact, you're already part-way to vectors when you say that — but not far enough. And when you're doing vectors, you're no longer applying the 1 + 1 = anything rule.

Of course, the word manhole refers not to a hole in a man, but to a hole which admits a man. (Or a woman, but not too many of those I've noticed. Jobs involving manholes do not include a corner office with a Wegner chair.) Which is why comments about Howard's ass are not off-topic.

Drago said...

"So if two similar cars, similar speeds, are racing down the highway going in opposite directions and they collide head-on, their combined velocity will be twice as much?"

You are using "speed" (a scalar quantity, magnitude only) in the same sentence as "velocity" (a vector quantity, magnitude and direction).

Your scalar equation 1 + 1 = 2 remains true, calculating the exit vectors after a collision between projectiles is quite different.

stevew said...

As to my earlier post of the manhole shape question: all of those answers above would have been judged correct by my high school teacher. His simplest correct answer is this: a round manhole cover cannot be dropped into the hole.

I correctly answered the question on the test, not because I'm wicked smaht but because I remembered he had mentioned the question and answer earlier in the term.

Humperdink:

There is a café thread from a couple-few months ago, where Mr. Meade recommended not watering plants left in a cold room for two-three weeks at a time. I just have these silly avocados grown from seeds, up in New England, that I've grown to love. In any event, and I might be incorrectly interpreting Mr. Meade's directions, but: I water them copiously every 2-3 weeks, or when I see that their water's turned to sand. It seems to be working.

Best wishes with your banana plant. (By the way - I've tried growing both bananas and pineapples, but cannot seem to get either to take.)

But it would be nice to figure out what sort of man you think Vlad Putin is. Is he a crafty genius who swayed an American Presidential election for peanuts? Or is he the dumber than a bucket of dirt idiot who knew that Trump’s support for fracking and the Keystone Xl and Dakota pipelines would cost him tens of millions of dollars in personal wealth? A conundrum. And now Trump’s deal to sell liquid natural gas (LNG) to Europe will take more business away from Gazprom and more millions out of the Russian economy.

Oh yeah, and somehow Putin inveigled 75K shares of Gazprom related stock into Hillary’s campaign manager’s hands, stock that was worth millions when Hillary was a 95% lead pipe cinch to win the election, and was worthless two days after the election.

Then you add practically every Assange data dump except possibly Stratfor was from an exfil not a external hack.

Michael McNeil said...

You are using "speed" (a scalar quantity, magnitude only) in the same sentence as "velocity" (a vector quantity, magnitude and direction).

Yes I am. So what? The former was being applied to simply describe the magnitude of the velocity of each of the opposite-moving cars — then the latter was used to describe the resulting motion, if any. Thus, they aren't apples vs. oranges at all.

Furthermore, your raising the scalar vs. vectors distinction only reemphasizes my point: one cannot describe phenomena such as physical motion (velocity, acceleration, et al.) with “scalars” — that is, simple numbers having magnitude but no more-involved complexity. For that you need vectors, or at least complex numbers — and neither of these behave like simple numbers. For instance, one cannot order either complex numbers or vectors by greater-lesser.

Thus, it is not true, in this application (along with many, many others) that “1 + 1 = 2”.

Your scalar equation 1 + 1 = 2 remains true, calculating the exit vectors after a collision between projectiles is quite different.

The “scalar equation 1 + 1 - 2 remains true” — absolutely true — only in the realm of abstract mathematics (like all abstract number theory), and relatively true (if it is) only insofar as it actually applies to aspects of the real world. Those as it happens are quite limited for simple numbers.

"So if two similar cars, similar speeds, are racing down the highway going in opposite directions and they collide head-on, their combined velocity will be twice as much?"

My thought was relativity, where 1+1<2. Or maybe 1/2+1/2<1. In our Newtonian space, we can pretend that 1+1=2, because the difference is not really measurable until V gets significant. But continuing those thoughts, Newtonian space is effectively Euclidian. One of the most fun classes I had in college was Non Euclidian Geometries. The northern and southern borders for CO and WY are not the same length, while the east and west borders are the same length, because the surface of the earth is non Euclidian. There, parallel lines do intersect (notably at the poles, but for any set of opposite points - we just select those opposite points to coincide with the axis of rotation for convenience).

If there are culprits here, it is the people in our government who directed our intelligence forces not to defend us against that meddling. It was the same thing as leaving the gate open with knowledge that the enemy was launching an attack.

Again, if you want to convince anyone of your sincerity, your targets should begin with those people. Purge them from public life, from the government and from their book deals and their soft bounce jobs in media and academia. Until that task has been completed, there's really no reason to think that complaints of Russian meddling are anything more than a political tactic.

1 - No treatment or cure for blindness.
2 - No breakthrough of any type.
3 - "God molecule" is not a molecule.
