Physics is so fucking fascinating, but at a horrible price, it is ridiculously difficult

[gredangeo]

Someone's been thinking too hard. :)

[Thomasnor1]

whoooooaaa! i am floaaating, man!

[TheHONKYLIPS]

i can sit on your moms face

[Bluedrake42]

um... what if sitting on the chair... means you're hovering over a chair... since when does "sitting" mean that you have to physically touch anything on a molecular level?

[raydredX]

@josepinnaple You feel chairs too when you sit on them don't you? Even though you aren't exactly touching it you can feel it. But the term touching doesn't make much sense in the tiny tiny world. It makes stuff simple in the macro world.

Therefore I'll say that I am touching this chair even if I'm not.

[Axiss360]

Does this mean I can't actually kiss my girlfriend? D:

[AraGuitar]

yes, but FOR ALL INTENTS AND PURPOSES... :P 

[mexicano7771000]

@josepinnaple Because the they have textures, and we can feel it. The repulsion is just like a layer over the actual mass. So if the mass suddenly dips (Like a crack in wood) the layer of electrostatic repulsion goes along with it like a blanket. Hopefully that helps (:

[JanPBtest]

He is not really incorrect but the way he says it he strongly suggests it's the electrostatic repulsion between electrons that does this. It does not, I think Dyson or Ulam calculated this precisely for the first time. What makes matter solid in this person-chair sense is the Pauli exclusion principle which the electrons obey (i.e. a purely quantum mechanical effect is responsible).

[josepinnaple]

Then why can we feel different textures? If i can feel the chair then I made contact with the chair. I think

[badjaeaux]

He's a Samurai

[angel951ism]

Thirds a tony little field around everything that is matter like a tiny shield or a invisible outline of matter, actually the only known person who actually touched matter was chuck.norris

[meandmyevo]

Chuck Norris can sit ON a chair.

[Fredkrug3]

You thought it was a person on the chair? Nope, chuck testa.

[Vonstuker4]

@AlphaCrucis what you say makes no sense, sorry

[AlphaCrucis]

@ZerkosXD It depends on what you mean by wrong. Newton's laws can be said to be correct as they accurately describe nature under everyday circumstances, yet they fail to accurately describe nature correctly under extreme cases such as in predicting the behavior of objects moving near the speed of light or in predicting the position of an electron near an atom.

[AlphaCrucis]

@Vonstuker4 You will get cut, but nonetheless, you still aren't really touching the chair

[AlphaCrucis]

@emporer15 The sensation of touch is due to the nerves in your body experiencing pressure. The chair, or more precisely, the electrons that comprise the chair repel the electrons that comprise your body so there is a force upon your nerves and you feel the chair.

[Vonstuker4]

Ok, so let me go make a chair made out of razors and lets see if i dont get cut

[NuovaCraft]

im 14 and i love physics. 

[hcvideoproductions]

@ZerkosXD But it's most likely true. One of the fascinating parts of Science is the journey into the unknown and finally finding new stuff, proposing new ideas, etc.

[ZerkosXD]

@hcvideoproductions and also it may all be wrong. i mean it's all theory.

[Mengster13]

I thought this was gonna be blooper of Dr. Michio Kaku falling his chair.

[msam1970]

Like I said " GRAVITY IS UP"

[Xephirox900]

@hcvideoproductions I can relate to that so well :(

[Etrajbe]

@emporer15 u feel the repelling of the electrons. the force in between, sorta.
