When we let politics trump science, people are needlessly put in harm's way. http://arstechnica.com/science/2017/01/self-censoring-fears...
Easy. x ≠ x.
ReplyDeleteReally, it could be anything.
ReplyDeleteAlso, 2=3.
ReplyDeleteCaution, it's easier than ever for offspring to prove their parents wrong: wolframalpha.com - Wolfram|Alpha: Making the world’s knowledge computable
ReplyDeleteDavid Schmidt It says, "No solutions exist".
ReplyDeleteFor large values of 2.
ReplyDeleteYeah, I think that's because no solutions exist.
ReplyDeleteX = (-1)^(1/2)
ReplyDelete2 + 2 = chair
ReplyDeleteCraig Froehle Did your daughter solve it?
ReplyDeleteX = https://lh3.googleusercontent.com/rmm9wq4XmPYZKqYj3DpeXF2pnT2FMxg4QOB2sJSCRQsTz6nbS3pTcXpTExjq0k0ki3yBHvKGrhAqHnTXMqlTXApVQbCdnRF5i9ff=s0
ReplyDeleteX = ∞
ReplyDeleteJim Douglas ∞ is a direction, not a number. I'm a bit negative, so I prefer -∞, which is the opposite direction.
ReplyDelete2 != 3, like Dan and Steve said.
ReplyDeleteThe solution to this problem can be found in a subset in the field of bistromathics (ref: "Restaurant at the End of the Universe, under the recipriversexclusion moniker)
hitchhikers.fandom.com - Bistromathics
ReplyDelete"recipriversexclusion, a number whose existence can only be defined as being anything other than itself"
ReplyDeleteIn IEEE floating point, the NaN (not a number) value does not compare as equal to itself. Moreover, any calculation involving this value yields this value.
So, on the one hand, "x + 2" is NaN when "x" is NaN, and so is "x + 3". On the other, the two NaN's aren't equal, because no two ever are.
(There are two flavors of NaN (quiet and signaling) and there are billions of ways to express each, as they're defined solely by the first 9 bits.)
en.wikipedia.org - NaN
Such things happens in Biology may not be Math --- In the beginning of time before anything (like #evil dad) existed x+2=x+2, But with the passage of time x+2 on rhs went thru Mutation and 2 on rhs became 2+1=3.
