Facebook hates Pythagoras: a²+b²=c²

And Wikipedia love/hates "a²+b²=c²" even more! = ☹

Are you a FaceBook user? And have you EVER tried to cut-and-past the Pythagorean-theorem of "a²+b²=c²?" [ I do it EVERY day :-^) ] ... But found your resulting paste gives the grotesque result of "a2+b2=c2?" ...

Now try to cut-and-paste this Facebook/Wikipedia version: "a²+b²=c²?"

Don't believe me? ... then try to cut and paste from either: Facebook: Pythagorean-theorem or Wikipedia: Pythagorean-theorem - Proof by rearrangement.

¢ Kind of typical of the 21ˢᵗ century... after 2½ thousand years of civilisation one cannot simply cut and paste Pythagoras's theorem of a²+b²=c² from wikipedia and share it with a friend on FaceBook! ☹ ¢

Fortunately WolframAlpha has no such problem, eg. click on: a²+b²=c²

Here is a useful table you from where you ＣＡＮ cut-and-paste ˢᵘᵖᵉʳˢᶜʳᶦᵖᵗˢ and ₛᵤbₛcᵣᵢₚₜ... ¢ oops... Note the b & c, maybe we need to wait until the 22ⁿᵈ century for the entire alphabet to be in all browsers? ¢

Ironically Wikipedia does detail how to achieve the alphabet in either ₛᵤbₛcᵣᵢₚₜ and ˢᵘᵖᵉʳˢᶜʳᶦᵖᵗˢ... Wikipedia: Unicode subscripts and superscripts.

But you can simply use this page: piliapp.com to: c̶r̶o̶s̶s̶ ̶o̶u̶t̶ ̶m̶i̶s̶t̶a̶k̶e̶s̶ or u͟n͟d͟e͟r͟l͟i͟n͟e͟ ͟i͟m͟p͟o͟r͟t͟a͟n͟t͟ ͟s͟t͟u͟f͟f AND THEN cut and paste it to share on FaceBook. Or use tiny-text to generate ˢᵘᵖᵉʳˢᶜʳᶦᵖᵗˢ.

And for even more find try: ₛᵤbₛcᵣᵢₚₜ @ panix.com

For the technically minded, here is a table of as many of the SI units that I could find, all ready for your cut-and-paste. ¢ Enjoy ¢
