## See An Electron Lately?

This is not about seeing an electron, but rather, the notion that seeing something with our eyes is the end-all requirement for the validity of anything. I will show that our human eye, as a light detector, is NOT a very good detector at all in many aspects, and thus, using it as the standard detector to validate anything is utterly irrational.

The motivation for this is that I often see a lot of ignorant statements on PF that either questioned, or dismissed something just because...

In another form I presented a proof (post #145)that the lim of 0.9999....=1 using epsilon delta arguments. I was asked to explain each step so I am moving it here for the latex support.

Quote:
0.999... + 0.1 = 1 + 0.099...
0.999... + 0.01 = 1 + 0.0099...
0.999... + 0.001 = 1 + 0.00099..
I do not prove this but it follow from basic arithmetic (by the way numbers carry in addition)....

Probably a lot has already been written about the Higgs boson and a lot more is still left to written. For some odd reason this particular discovery has grasped a lot of media attention.People who were clueless about the existence of the LHC are now avowed experts on the subjects. Some even claim to have an understanding about it, even though the scientists are themselves clueless about it!
