((x-a)(x-b))/((c-a)(c-b))+
+((x-b)(x-c))/((a-b)(a-c))+
+((x-c)(x-a))/((b-c)(b-a))=
=1 (and not 0 as it was written in previous variant, im sorry :()

u can see that its a 2nd degree equation for x, but how come that it has 3 roots a,b,c? i mean if u put in the place of x any of them equetion will be true

That's the feminist's 'logic' if things are reversed, right? He's tied [oppressed] to the stove whilst his wife is enjoying things on a freezing building site, right? He's allowed endless of slavish cups of tea [poor thing] whilst she's only allowed to eat or drink at meal times, right? This is all if we take the feminist's premise that to stay at home is 'oppression'.
Btw, the easiest job a person can have is sitting at home looking after kids. Trust someone who's done it for 8 years. It doesn’t get any easier than that, that's why no-one wants to pay anyone for doing it.

Ok I understand that light moves in basically a wave form threw space, and it is effected by gravity in a similar manner then other things. From what I understand is that Einstein therorized that as we get closer to the speed of light time slows down. What I don't understand is why going fast would make time slow down. And if time does slow down how fast does it decelerate. And if you can measure how fast time is moving, what do you measure it in seconds per minute or what? I just don't understand what makes einstein think that.

Due to a poorly worded question on Monday, the super smart science guys n gals were deprived of a chance to flex their brain muscles.

Therefore, here is the improved question on Forces and Physics.

The new Appledium is a new design in car, 0-60 in 12s, 20mi to the 1l, and a braking force of 4,800N. It is ultra light at just 1,200 Kg.

A careless child runs out on the road whilst the car is traveling at 40 m/s. How many seconds will it take the car to stop.

As always, lets see your working (So that none sciencey people can understand the answer better, it is solvable and gives a chance for those in the know to show off they know, and those who don't to see how it is done.

1300 today for answers.

The Appledium is a fictional car created for the purpose of this question, just to prevent anyone making fools of themselves at the dealership.

I've read a bunch of different papers on it, and it seems to pretty full of holes, but I think it's because nobody has ever done a good job of explaining it to me. I understand that Einstein said nothing can accelerate up to the speed of light. I understand that if you put a watch on an airplane there is a difference in how fast it ticks. But I'm still not exactly sure why, or how Einstein thought of that. Keep it simple if possible I don't feel like reading a bunch of equations.

If this is the case, then what happens when it is closed ? Does this mean that a new ice age is on the way ? So, should we be burning more fossil fuels to keep us warm and reopen the hole ?
Should I buy an American gas guzzler in an effort to save the world ?

It is time for science knowers to strut that Brain power for all to
see, and non science people to perhaps pick up a bit of knowledge.

Plutonium 239 emits an alpha particle every 7 seconds. What will the new nucleus look like after 1 minute.

You know the drill, It is solvable, not a trick question, and just a
bit of know-how is all.

Hi,

I need to harden some aluminium gears for my sons RC car, as they are cheap and keep wearing through.

Unfortunately there aluminium, so I can't flame harden them. Any ideas what process I can use to harden them?

Cheers!
