I'm sure some smarter person will emerge here tomorrow to answer an even tougher quantum mechanics question from @humfrz.

Something like how fast are electrons travelling down some length of copper at an amount of current and specific frequency?

I think I actually had this same problem at some point at college. But it's far too late to start thinking about calculus. Some of us still have to work in the morning...

PS. Now I'm thinking about calculus. . I'll solve it tomorrow. If I remember. Hopefully I forget all about it.
We will be waiting .......

After looking at some of the new threads being posted by brand new members lately, I have come to the conclusion that this car has officially become the ten year old civic of the import world. I'm not sure if I'm more baffled by the "will the OEM option part break my car" or the kid trying to drive up views to his YouTube channel by making videos saying that it's cheaper to buy mods used. I can only assume the channel is monetized.

Maybe I'm getting old. I'm all for answering genuine questions and being helpful, but damn. Tons of resources are available on this forum, and none of them are being used even after they're pointed out.

We don't need to answer questions anymore since Gforce/Ubersuber/Suberman is back.

For god's sake never tell a 17 year old that a Miata engine would suck in a Twin or you will have ruined their dreams and they will want to beat you up.

If you tell somebody that they will need more than $500 worth of extras to do an engine swap you be the devil incarnate.

You should see some of the PMs I got from some of the noobs recently.

I see the phrase "pull the trigger" far too often. How many people using that phrase have ever actually pulled a trigger before? I suppose if they had pulled a trigger, they'd know to squeeze it instead.

really liked Montreal. cool looking city. roads were a little crazy with the one backwards lane but otherwise pretty cool. great food too. can't wait to go back and not be on crutches. that really limited my ability to get around.

weather this time of year is GOAT too. sunny and mid to low 70s. funny thing, one of the hosts at the plant we went to said, "sorry you had to come up in this miserable weather.". we were baffled. the only reason we could figure was it was kinda overcast. perspective I guess.

Montreal is one of my favourite cities in the country. Highly recommend it. Good food, good sights, great beer. What more could you want?

What's wrong with people these days.

We didn't need forums on the interweb during the dial-up days in order to be informed or misinformed. There were something known as quality automobile publications and Japanese bootleg car tapes on VHS.

What color rims should I get for my car... Like really? Pussification of modern society in full effect.

BTW that argument thread on suspension is hilarious. We knew even back in elementary school that double wishbone is the shit! Then again most of my classmates had Honda and high end Toyota (Lexus) cars in their parents' garages. We also didn't have retarded movies like Fast & Furious to tell us that vtec kicked in yo!

I don't know enough detail to be able to complete it so took some guesses, but it can be done online here.

My very limited knowledge came up with 325ft/s at impact, but I have about 25% confidence it's close to correct.

smoking hawt womenz too. you can see the French lineage in them but they're just a little "thicker" where it counts.

Probably the poutine. the only way everyone isn't morbidly obese is all the walking and not eating that very often. because if you ate that everyday and sat at a desk. you'd be super fat in no time.
