Use this thread to ask any old question you fancy an answer to, but can't be bothered to research in the proper manner like any normal, self-motivated, self-respecting person with a bit of get-up-and-go would. Questions that aren't worth starting an individual thread for. Anything from "what the hell is psychogeography?" to "how do I fix my leaky toilet?" Alternatively, use this thread to show off your mighty knowledge by answering a question or 2 or 3.

Note: People asking rhetorical questions for tiny comic effect (eg "What's it all about, then?" or "Why?") will be punished to the full extent of the law and beyond.

I'm going to kick off with an exciting maths question:
Q1 How do you convert slopes expressed as angles (eg 45 degrees) to ratio type gradients (eg 1:1) without resorting to pencil, paper and protractor? I'm specifically interested in knowing what 3 degrees would be, so an answer to that would be nice, but if the method isn't too taxing, that'd be handy to know. As they say: "Give a man a fish and he'll eat for a day; give a man a rod for his own back and he'll beat himself senseless all day, every day for the rest of his life."

I like the idea of this thread Saveloy. A kinda Lithian Notes & Queries. We'll have to take care that those with answers quote the question, otherwise it could all get very confusing as the thread grows - (But oh the comedy potential!)

Here's my question:
As a schoolboy I was taught that cells in the human body die and regenerate in such a way that after a handful of years you share no cells with your younger self. (I seem to recall it raised concerns with theories of personal identity and comparisons with the trusty old broom that'd only had 3 new heads and 2 replacement handles). Anyway, if this is true - how come tattoos last for so long?

"We'll have to take care that those with answers quote the question, otherwise it could all get very confusing as the thread grows"

You're right! Not that this thread will grow much; it's been my experience that as soon as someone says "what a good idea" the thing sinks like a lead turd. But just in case, for reference purposes, let's call this next question Sav2:

In the "Explain punk..." thread in the Music forum, tSuibhne says:

"The [punk] label has gotten spread pretty thin since it was first used to describe 60's garage."

Was garage actually called punk during the 60s? If so, who first used the term, where, and when? I'm not saying it wasn't, but I'd always been under the impression that the label was applied retrospectively.

(I'm asking the question here rather than in the original thread to prevent derailment).

I be Mighty, although only when provided with a hand-cranked abacus.

For angle x, ratio is tan x : 1, although you'll want to multiply that up to something nice. 3 degrees gives 0.0524...:1, or 1:19.08 or so.

I think.

'what the hell is psychogeography?'

Whatever you want it to be:

"Nothing is more delightful than to confuse and upset people. People one doesn't like. What's the use of giving them explanations that are merely food for curiosity? The truth is that people love nothing but themselves and their little possessions, their income, their dog. This state of affairs derives from a false conception of property. If one is poor in spirit, one possesses a sure and indomitable intelligence, a savage logic, a point of view that can not be shaken. Try to be empty and fill your brain cells with a petty happiness. Always destroy what you have in you. On random walks. Then you will be able to understand many things. You are not more intelligent than we, and we are not more intelligent than you."

Why do mirrors reverse things left-right instead of top-bottom?

Mirrors don't reverse anything they just reflect. All the stuff on that side is still on that side seen in the mirror, the same on this side, ditto top and bottom. If you had something that reversed, perhaps in order to show an image of yourself as others see you, you could mount it on it's side to reverse to to bottom instead.

Q. If I were to send a low value item like a stick of rock (some candy) to the USA would I have to make a customs declaration? Would I have trouble sending consumables? Has anyone done this successfully?

Sorry Feature - I don't understand. I was thinking of it this way:
You're standing in front of me holding a big clock (let's say it has one hand and no numbers on it - keep it simple). I have an identical clock face and my job is to make my clock mirror yours. You move the hand to the 3 o'clock position, I move mine to the 9 o'clock. Yours goes to 11 o'clock, mine goes to 1. Yours goes to 12 and so does mine. In other words, when I 'mirror' you all these translations take place across the vertical (y) axis, and not the horizontal (x) axis? When you go to 3 I go to 9, but when you go to 12 I don't go to 6. Why? Why the y?
Am I being an idiot?

Question:

When studying the history of the Hollywood Studio System (the old one that is, '30s-'50s), it was repeatedly made clear to us that directors usually had absolutely no say in choosing the scripts they directed, they simply had to put up with them..

Yet a considerable part of studying Auteur theory as it relates to Hollywood consists of discussion of the plotlines and dialogue of the films of Howard Hawks, John Ford, Billy Wilder et al. and how these reflected their particular preoccupations and world-views..

Can anyone solve this enormous cinematic paradox?

"Hey! I've got a pair of shoes that I really like, but they squeak horribly. Any suggestions on how to make them quiet(er)?"

If they squeak due to walking on the floor yet they don't on carpet then it's because they're new and you'll want to skuff up the soles a bit.

If its the actual shoe itself that squeeks , try putting some talcum powder where they squeek.

(I seem to recall it raised concerns with theories of personal identity and comparisons with the trusty old broom that'd only had 3 new heads and 2 replacement handles).

Because tattoos are made of ink placed between layers of cells. The individual cells may die or migrate, but the ink stays put fairly well. Over time, it blurs and fades as skin cells migrate and stretch.

Q. If I were to send a low value item like a stick of rock (some candy) to the USA would I have to make a customs declaration? Would I have trouble sending consumables? Has anyone done this successfully?

Yes, technically, you would have to declare, and as long as they're not perishables, meat or fruit (or prohibited drugs), there shouldn't be a customs problem. And if it's a small amount, I wouldn't worry about it. I've gotten stuff from South Africa... actually, there's a package of seeds one of my uncles sent to me that arrived yesterday. Technically illegal, it got through with no problem.

a considerable part of studying Auteur theory as it relates to Hollywood consists of discussion of the plotlines and dialogue of the films of Howard Hawks, John Ford, Billy Wilder et al. and how these reflected their particular preoccupations and world-views..

Because these were the directors idolized by the writers at Cahiers du Cinema, the French journal whose contributors included Godard, Truffaut, and all them Nouvelle Vague filmmakers. They noticed that *despite* the limitations of the studio system, certain directors maintained a powerful sense of personal style; that certain films could only be made by certain directors while producers or writers or cinematographers were largely indistinguishable, and that thus the identity of the film relied upon the authorship of the DIRECTOR.
The auteur director was thus a rebel fighting the authoritarian regime of the studio system, and deserved to be freed from bondage - which was a big part of the mission of the New Wave filmmakers.

Sorry smoothly, my explanation lacks a diagram but here goes.

Imagine I am facing due north holding your clock with the face facing north. The mirror is in front of me facing due south.

The clock reads 3 oclock.

The short hand on the real clock is facing west, The short hand on the reflected clock is facing west. Both the real hand and the image in the mirror stay on the same side (the west side), they are not reversed. The big hand points points up in both the real clock face and the reflection, it too is not reversed.

The mirror does nothing fancy, the light rays traveling in a straight line from the clock hands have bounced off the reflecting surface and hit your eye.

Our experience tells us that light moves in a straight line, the image we see appears to be behind the mirror but you will notice, still on the same side.

A reversed or 'true' image could be produced by bending the light with a lense or using a curved miror to change the angle of reflection.

Why does Venus spin in the opposite direction to the rest of the planets in our solar system?
 
 
Grey Area
19:19 / 10.09.02
Tezcatlipoca:

There are two widely held explanations. The first is that Venus' reverse spin was brought about through gravitational interaction with the Sun. Imagine a spinning ball being stroked by a feather in the opposite direction of the spin. Assuming that the ball has no other influences upon it's rotation other than the feather, given enough time the feather will reverse the spin.

The second explanation involves the effect of atmospheric forces bringing about a reversal of the rotation through friction over a loooong period of time. Essentially the same thing as the feather-example, but with the forces in play being atmospheric.

(Note: If I'm totally wrong here, feel free to shoot me down in flames...)

Grey Area: It sounds plausible enough. Have you considered this explaination, though?
 
 
Saint Keggers
20:53 / 10.09.02
T.O.D.D.: Get a smaller measuring tape made from the same material then measure its diameter and the multiply its length by what ever number you would need to make it 12 miles long then use that number and multiply the diameter of the smaller tape by it to get the diameter of the 12 mile long tape.
(this is all just theory off the top of my head)

[TECHY QUESTION]My old PC has a soundcard plugged into an ISA (is that right?) slot. New PC soundcards seem to all plug into something called a PCI slot. So my question is:

Q) If I bought a new PC, would it still have a ISA slot in it to plug in my old soundcard? 'Cos my old soundcard is rather nice (with 24 meg of sample memory and all that).[/TECHY]
 
 
Grey Area
09:41 / 11.09.02
ISA slots are pretty much history, as most modern motherboards include only the PCI-type slots. This is mainly due to the fact that the PCI slot is more compact and is faster than the old ISA standard. You can find PCI to ISA adapters, here, for instance, but they're specialist items (read: bloody expensive) and there's no guarantee that it'll fit into your casing. You're probably going to have to buy a new sound card. Creative's Audigy is rather nice.

Cheers for the info... Am a little sad to have to dump my trusty old soundcard. Progress? Bah Humbug! Still, looks like the new Audigy would do everything I wanted. But does it have sample memory on it? It doesn't mention any on the specs page...

Related to my slope question, this - is there such a thing as a not-too-pricey (or even shareware) bit of software that will simulate the motion of an object over a given landscape. What I want to do is draw a bumpy slope and then see how a wheeled vehicle would travel down it, and I want to be able to muck about with the parameters (weight, mass, materials etc) Engineers and architects must use hugely expensive and complicated professional versions all the time, but my needs are fairly simple and my means limited....

Thanks Featch

You say that flat mirrors don't actually reverse things, but if I hold up some writing to a mirror, it looks kinda...er...reversed. And moreover I notice that a 'b' becomes a 'd' and not a 'P'. In translational terms 'b'-'P' is as much of a 'reversal' as 'b'-'d' is (isn't it?), only through the x-axis rather than the y. Flat mirrors seem to opt for (or give the appearance of opting for) the y-axis flip. Why?

Surely if it's visible in the mirror then it's facing away from you....
