# Another encrypted things

Inspired by encrypted fruits and vegetables, this simple puzzle encrypts a set of things having a common topic. So, please, figure out the topic itself (unlike the linked questions, clues are comma-separated here unless the commas are within parentheses, braces etc.):

1. π€, $$\boxed{6}+\alpha\to?$$
2. $$\dfrac{F}{x}$$, π
3. $$\boxed{83}$$, πͺ
4. $$\boxed{19}$$, π¬π§$$(v_4-v_1)$$
5. $$0.0075\ \mathrm{mmHg}$$, πͺ[0], $$\{0,1,2,...\}$$
6. $$I^2Rt$$, $$\boxed{92}$$, $$\approx7.38906$$, $$0.10197\ \mathrm{kgf}$$

These rebuses resolve as follows:

1. π€, $$\boxed{6}+\alpha\to?$$

ROOK = ROCK, changing C (element#6 = Carbon) to O by adding 12 alphabet positions (alpha - this element's atomic number - is 12) [NB OP's intent was that Carbon plus an alpha particle becomes Oxygen, i.e. C becomes O]

1. $$\dfrac{F}{x}$$, π

KNIGHT = K (F=kx, Hooke's Law) + NIGHT

1. $$\boxed{83}$$, πͺ

BISHOP = Bi (element#83 = Bismuth) + SHOP

1. $$\boxed{19}$$, π¬π§$$(v_4-v_1)$$

KING = K (element#19 = Potassium) + (possibly) ENG, performing some kind of vowel manipulation I can't quite pinpoint...?

1. $$0.0075\ \mathrm{mmHg}$$, πͺ[0], $$\{0,1,2,...\}$$

PAWN = Pa (Pascal) + W (0th element of WINDOW) + N (the set of natural numbers)

1. $$I^2Rt$$, $$\boxed{92}$$, $$\approx7.38906$$, $$0.10197\ \mathrm{kgf}$$

QUEEN = Q (Joule's Law) + U (element#92 = Uranium) + EE (7.38906 is approximately e squared) + N (Newton)

All of these are:

CHESS PIECES!

• Wow you solved it all before I attached a community wiki Mar 18, 2021 at 8:08
• Great! However, the intended solution for 1 was a bit different, namely rot13(nqqvat nycun cnegvpyr gb pneoba cebqhprf bkltra). Also for 5, rot13(gur rzbwv vf "jvaqbj", naq gnxvat mrebgu ryrzrag [0] bs "jvaqbj" vf "j"). Mar 18, 2021 at 8:26
• @trolley813 Aha, okay, that makes more sense! I'll amend my answer, and see if I can nail down 4 completely too...

• Well, the intended meaning for 4 was rot13(va Ratyvfu tenzzne (urapr gur HX synt), I4 qrfvtangrf cerfrag cnegvpvcyr bs n ireo (r.t. ernqvat), naq I1 vf vasvavgvir (r.t. ernq). Fhogenpgvat I1 sebz I4 (bs gur fnzr ireo) yrnirf "vat" fhssvk (gung'f gehr sbe zbfg ireof)). Mar 19, 2021 at 19:20
