So here are a couple more.
I have included an inversion to show how the impression is often quite different. But you can always do it easily yourself in Gimp.
The Chinese characters are wu-wei, the Daoist concept of getting things done naturally, with out scheming or manipulating.
Images are not visible here (USA), though it appears Walter can see them. Anyone else having trouble seeing them?
I'm in the USA and I can see them OK.

I can see them, but I'm not grokking them. Translating m c ↑ 2 × E - to algebraic yields 2 * m^c - E... Maybe that's a famous equation, but not one I recognize.
:lol: These errors would not have happened if you (pica) had chosen this form:

May I guess you are spoiled by RPL (but not sufficiently)? ;) One can do the postfix notation to death but may fall in pits ...

Thanks Thomas. Weird, I can see them in Chrome, but not in IE11. That's new.

I think he meant the power of 2 applies to the c, but you are right that's not what it says. And m to the c is a lot of m, but not so much E....

Hmm. Maybe I am a bit spoilt. I am now in a dilemma.
E=mc^2 was going to be boring, on grounds of being so famous that it is commonplace.
An RPN program listing was not pretty enough for my liking, so I compromised, but I guess it is a bit of a mishmash now.
Maybe <<m c 2 ^ * E - >> as pure RPL should be the way to go, but is this appropriate for an RPN machine?
I am willing to bend to advise from other authorities and redo it when there is a consensus on a good RP* rendering.
Or maybe <<E m c 2 ^ * - >>

On the other hand Thomas, c squared on my DM42 definitely comes out as c ↑2

Odd that some people don't see the images. I may live in a planetary backwater, but dropbox links should be mainstream.

Thanks! Hard reading times for internationals. But what doesn't kill us makes us stronger.

In the '70s there was a T-shirt for Star Trek fans that read, "I grok Spock"

Must be a USA thing. Perfectly visible here in the UK.

So far Bob is the only one who said he can't see them. Tom L and I both can, so assuming the problem is network-related, it's pretty localized, since neither Tom L nor I are very far from where Bob is.
