# Talk:2034: Equations

Is the joke that all of the equations are actually wrong/malformed/meaningless but they sort of look like typical equations for that field?

- Sort of. A bit of dimensional analysis would have helped. ;-) --162.158.91.221 07:28, 17 August 2018 (UTC)

Should we add a column with examples of similar correct equations from the respective fields? Sebastian --172.68.110.4 09:33, 17 August 2018 (UTC)

- That would definitely tidy up my attempts to provide context for Randall's versions. The challenge then is working in explanations for the correct equations as well as arguing over which examples should be used. Exxi (talk) 09:45, 17 August 2018 (UTC)

I don't think the part in parentheses about OH in the Chemistry equation explanation is correct. OH- would mean that it's negatively charged and has nothing to do with unpaired electrons of Oxygen. It would add another horror to the equation, though, as it wouldn't be charge preserving anymore. 162.158.88.230 09:58, 17 August 2018 (UTC)

"Redshit". Best typo ever. Please keep it. 172.69.54.177 10:13, 17 August 2018 (UTC)

## Deep physics equations

The transcript is wrong here, the last letter is not a , but a "u" with a cedilla: u̧. The math parser refuses to render it, though. 162.158.88.230 05:54, 17 August 2018 (UTC)

- Looks like it. But I don't think that letter exists even. --162.158.91.221 07:28, 17 August 2018 (UTC)
- Is this equation a sort of nod to a Theory Of Everything which unifies quantum mechanics and gravity... H-hat (a Hamiltonian, which in quantum mechanics describes the total energy of a system, and usually runs in to problems describing large systems - such as the entire universe - where gravity or spacetime curvature effects matter) *minus* u0 (the relativistic mass of the whole system at time zero ie. the big bang) gives 0 (no energy everywhere always). Since mass is energy (e=mc^2) and mass is also the sole cause of gravity the two theories cleanly collapse together when mass is zero, and figuring out how to extend the theory to other less clean points on the mass axis is obviously a job for less profound physics? I've no ideas to explain the cedilla. 141.101.98.28 08:49, 17 August 2018 (UTC)
- It looks to me a little like a parody of the Wheeler-DeWitt equation which (in theory) describes a wavefunction for the entire Universe. Exxi (talk) 09:06, 17 August 2018 (UTC)一

Is this poking fun at equation-filled blackboards in movies and cartoons?
