Oooh, define "definition"
Or describe blue to a colourblind person.
Etc.

Somehow, I'm tempted to trust everyone else on this one rather than one person claiming to have done this at degree level (whatever degree that might be).
But you'll trust wikipedia? C'mon man...
Nothing against you, but you just can't trust people on internet forums
No offence taken. I know I'm telling the truth (Bsc Hons. Software Engineeering btw), but you don't. Seriously though, don't believe Wiki or School though, they'll tell you there's such a thing as a solid and not something that's 99% free space held together by VdW forces. :)
Maybe I'm just too stupid to comprehend (most likely, acutally), but I don't get your "proof", while I have no problem understanding the proof of .9 recurring equaling 1.
Nothing to do with smartness, but I'll try another disproof anyway.

Ok. Let's say .9 recurring = 1

That means that the .0 recurring 1 = 0

That means 10 times .0 recurring 1 = 0

That means X times .0 recurring 1 = 0

Now 1 + N times .0 recurring 1 = 2 (Basic addition)

So 1 + 0 = 2

So 1=2

That made me laugh, so thanks for that, but I still didn't get it...well, whatever, it's late and I don't really care anymore.

The Blinovitch limitation effect is a physical, real limitation which prevents time travellers from interfering with their own history. It has two manifestations, one which prevents time travellers from changing their own past, and one which prevents a time traveller from meeting themself.

The key word here is "Limitation"; that is, the effect limits the amount of interference in the past as opposed to completely prohibiting it. Although it still isn't recommended for the reasons below.

In its first form, the effect is simply a time loop. Blinovitch stated that time is non-linear, and can become circular. A time traveller attempting to change their own history, for better or worse, will simply just create a time-loop, where his or her actions in the past are pre-destined and in fact have already happened.

Basically making the travellers future more "fate" oriented as events are destined to happen the same way again and again.

Time loops are paradoxical in nature, and to occur, time travel across time-streams must have happened. Of course, visiting your own personal past is only possible by crossing your own time-stream.

The Blinovitch limitation effect also has a second form, in this scenario it manifests itself as a force which prevents time travellers from interfering directly with their own past selves.

Basically, someone can't re-do something they have already done.

The force which intervenes may take any known form, manipulating chaotic and quantum variables in a weak manifestation, and manipulating explosive energies in a more violent manifestation. This form of the Blinovitch limitation is related to time eddies, a phenomenon which occurs when localised time runs in reverse, or circles round and round in a whirlpool like fashion.

It may be surprising to learn that both forms of the Blinovitch limitation effect can be circumnavigated.

To cancel out the time-loop in the first instance, it is necessary for an external time-traveller not previously connected with the time-loop to interfere with the creation of the time-loop. This may sound like interfering with a past-event, but there is a subtle difference here. A time-loop is not a real event. Once a time-loop is destroyed, the energy it had consumed to create its alternative reality is released back into the real universe.

Note this time that the destruction of a time-loop is a real event, and any attempts to change this will prevented by the second form of the Blinovitch limitation effect.

However, the second Blinovitch limitation effect can itself be avoided. The trick is simple: cross time-streams. The Blinovitch limitation effect only occurs as a result of a time-traveller meeting himself in his own time-stream. By meeting oneself in another time-stream, the effect does not take place.

Basically, in the event a time paradox...

ahem...

...the event can still be altered based on the circumstances to correct the The Blinovitch Limitation Effect.

No problem. Ask someone in your Uni to explain about Zeno's paradox sometime. Or even Fermat's Last Theoreum. That will blow your mind :)

If all truths are knowable, then all truths must in fact be known.

more of a brain twister than a paradox though...

The following statement is true.
The previous statement is false.
Question, how exactly do "contradiction" and "paradox" relate? Is a paradox always a contradiction? Is a contradiction always a paradox? If the answer to at least one of those is "No", then: How to differentiate?
differentiate thus;

to contradict is to be at opposite ends

to paradox is to always end up at the beginning

here is one

if men are getting taller

why are women getting smaller?

surely it makes sense for them to be getting taller aswell?
it confuses me ._.

Which means this is a lie. Which means you sometimes tell the truth, but not always, this case in particular is a lie.
Your false dilemma does not create a paradox.

Duno if it's much of a paradox, but I always liked the one theory about how you furniture moves about when you're not looking.

Ahh good old quantum physics.

I suppose you could look at it that way. I got it out of the dictionary a while ago lol.

There is one barber in a town who cuts the hair of everyone who does not cut their own hair. Who cuts the barber's hair?

Therefore, if you rearrange it, mass can create energy (in the form of movement). At least I think so. Someone correct me if I'm wrong.
What do you think they do in a nuclear plant?

Himself, you never said that he only cuts everyone else's hair.

A beam of light at the wavelength of around 440?490 nm. Now describing the concept of colors to a colorblind person may be tricky.

(not that this is a paradox, it's just a philosophical riddle)
Yes, because sound is just movement of pressure waves through a medium.
If your going for the more "no one obseverse it, so does it really happen?" angle, then you just have Schrödinger's cat in tree form.

I'm afraid this doesn't work. If the .0 is recurring, there can't be a 1 at the end, because there is no end to place it at.
