If you want to learn about physics wouldn't it be more fun to use example systems from this site.
I'd much rather learn about the acceleration of connected bodies using the tie me to a christian example than the standard car and caravan one.
Two christians one weighing 57kg and the other
weighing 20kg (a child perhaps) are connected together and connected to a monkey carrying a custard pie weighing 30kg. What is the rate of acceleration of the combined system during rapture.
Assuming the monkey must traverse a 4 mile wide estury, and so detaches from the christians and opens his monkey paraglider (glide ratio 7). How high must the monkey be before detaching.
Problems like this may motivate students better than traditional ones.
It would be good to set up an index idea which linked to physics topic ideas in the bakery. These topics would then link to all the HB ideas which involve this aspect of physics. Links would then be made on these ideas to external websites which carried detailed models of the mechanics of the idea in question. Worked examples would also be offered to validate or invalidate the HB idea in question.

I think the textbooks of the future, written by people who learned this way would be rather heavy on the custard references though. |
|
| |
[squeak] I suppose the use of a diverse range of puddings could be encouraged to combat this. |
|
| |
I dunno [tobyp]. I think it might be kinda hard to wean them off it. Maybe start with chocolate custard and move slowly to chocolate mousse. plus for the idea though. |
|

While I'll be the fist to agree that there is not nearly enough creativity in science (which is the main poblem with my job), I'd be concerned that there's too much dubious stuff on here. Many of the halfbakers know a great deal about physics or at least where to go to get such information. However it'd still be too easy for some credulous youngster to put too much faith in annotations that are misinformed or just plain silly. |

My physics teacher used utter nonsense as a teaching aid. He'd invent stories about setting fire to cows, and getting his tongue stuck on a bus stop on a particularly frosty morning. He'd vaguely tie his lecture into some theory or other, and then throw a blackboard duster at anyone who objected. |
|
| |
As I've graduated to be an utter dullard, I'd find it hard to recommend this method. Yours is much better. |
|
| |
[squeak] Also, if you read some of the time/quantum mechanical/gravity postings you'd also get some very odd ideas about the laws of physics! |
|
| |
That's one large custard pie. |
|
| |
Must disagree with this one. Clearly no one around here knows anything about physics. |
|
| |
Ooh I almost posted on my own idea under a different nickname, but deleted it in time, phew. If only I'd remembered my original password I wouldn't have had to bother setting up an alternative name at home when I had to post that earth shattering idea I had a few weeks ago just incase I was hit by a bus before getting in to work and risk losing it for ever. And then what with swapping between IE and Opera at work I nearly made a right cock up. |
|
| |
Anyway well spotted [RayfordSteele] I was wondering if any one would pick me up on that. monkey + pie =30kg |
|

[goff] and [waugsqueke] the person/people using the bakery for this purpose would create the HB index, add the physicis-sub-topic HB-idea pages which link to the fantastic existing HB ideas, create the non-HB external diagrams and worked examples and link to them from the selected HB idea (perhaps with a PHYSICS-TUTORIAL prefix on the link title) so these authors would ensure that the physics point being discussed was valid, or in the case of disproving an invalid concept, the physics in the disproof .. was valid. |
|
| |
You'd have to choose carefully though - I'm not sure the standard length of a school physics lesson is long enough to cover even one of [Vernon]'s ideas. |
|
| |
At the very least the HB could be used to provide many examples of how Physics *doesn't* work, thereby eliminating all those misconceptions under which the kids of today seems to labour. |
|
| |
I hated Physics with a passion at school - though I now realise it has its uses. Whilst some of the ideas in the HB could have lightened the way somewhat, I suspect that the rubbish nature of my A-level Physics teacher would probably have put paid to any learning benefit. + for the optimism though. |
|
| |
I've been here for several months and I haven't learned a thing about physics. In fact, I think I have picked up some very poor science in that time. So if you really feel the urge to try to teach me some physics, please do. |
|
| |
So anyway, there's this spherical goldfish bowl... |
|
| |
A wag remarked that so many physics textbooks use similar cliches in their examples, for instance a cow as a dead weight, or a frictionless surface, or a perfect sphere, that there had to be some "ultimate" physics problem that combined all of them. |
|
| |
"Consider a perfectly spherical, frictionless cow..." |
|
| |
Using the HB to teach physics would be like using the Tacoma Brisge Disaster to teach engineering... oh wait, they do that. But, what happens if an impressionable student comes across one of those faster than light ideas that claim a photon travels in a squiggly line, or a [sealorator] clone trying to ressurect caloric theory. |
|
| |
Maybe a separate website would be a better idea. I study and work in physics and I love it with passion. We need physics teachers who still have the enthusiasm they (may have) had when they were studying. |
|
| |
For example, I had a lecturer who always brought some weird toy to his lectures. Like, to demonstrate that things fall at the same rate no matter what their horizontal motion is, he had a small stuffed gorilla and a paper pellet gun... |
|
| |
Have to disagree with waugs that no one around here knows anything about physics. The difficulty is in determining the annos of those who do, from those who don't. |
|
| |
And separating light from dark, and [Vernon] from [Abhi]. |
|
| |
[jutta] Its the idea of a tree of HB pages serving as contents pages, etc that's offensive, isn't it? |
|
| |
a more modest version with an external index, but still with the PHYSICS-TUTORIAL-Link prefix, would that be more reasonable? |
|
| |
I think I'm okay with my accounts now, but thanks incase I decide to retire one of them. |
|
| |
[Hazel] I agree with you. I think its far more important to show someone their misconceptions and correct them, than to just give them model answers and learn-by-rote procedures. |
|
| |
I liked Physics!! but when my attempts at solving problems crapped out, I wasn't interested in knowing an alternative method i just wanted to know why my method failed and fix it or see why it was completely unworkable before I resorted to the boring stock procedures in the text-books. |

Man, I must need new batteries in my sarcasmotron. |
|
| |
Steal them out of your orgasmotron. You don't use it anymore, do you? |
|
| |
Who needs batteries if you've got a //perfectly spherical, frictionless cow//? |
