    I love how they deliberately chose a temperature such that it has the same value in both Celsius and Fahrenheit.

  • Chio-chan no Tsuugakuro 12

    So I was rewatching Chio-chan no Tsuugakuro, and I got completely nerd-sniped by this geometry problem.

    I don’t think my solution is the most elegant, but here it is.

    I have made the assumption that the line labelled “3” is parallel to the line labelled “A”. I will also make the notational change to use lowercase “a” instead of uppercase “A” to represent the required length.

    Label the points and angles as follows.

    By congruence, \( \alpha = \alpha’ \).

    Considering \(\triangle CBD\), \(\alpha + \beta + \gamma + \delta = \pi \); considering straight line HBG, \(\alpha’ + \beta + \gamma’ + \delta = \pi \). Therefore \(\gamma = \gamma’\).

    Lengths \(CA\) and \(AD\) are found by Pythagoras’ Theorem, and lengths \(BF\) and \(FG\) by congruence.

    Note that \(\triangle HBA \sim \triangle HGJ\), so

    \[\frac{b}{b+\sqrt{7}+\sqrt{40}} = \frac{3}{a}\]

    which gives

    \[a = \frac{3}{b} \left(b+\sqrt{40}+\sqrt{7}\right). \tag{1}\]

    Consider \(\triangle HBA\), we have

    \[\cos(\beta+\gamma) = \frac{3}{b},\]

    so

    \[\cos\beta\cos\gamma - \sin\beta\sin\gamma = \frac3b.\]

    The sines and cosines of \(\beta\) and \(\gamma\) can be obtained by considering \(\triangle ABC\) and \(\triangle ABD\):

    \[\frac{3}{4} \cdot \frac{\sqrt{40}}{7} - \frac{\sqrt{7}}{4} \cdot \frac{3}{7} = \frac{3}{b}\]

    which rearranges to give

    \[\frac{3 \left( \sqrt{40}-\sqrt{7} \right)}{28} = \frac3b \tag{2}\]

    and

    \[b = \frac{28\left(\sqrt{40}+\sqrt{7}\right)}{33}. \tag{3}\]

    Substitute (2) and (3) into (1), we get

    \[a = \frac{3 \left( \sqrt{40}-\sqrt{7} \right)}{28} \cdot \frac{61\left(\sqrt{40}+\sqrt{7}\right)}{33} = \frac{183}{28}.\]

    Can’t see much detail but where are white’s pawns?

    They fixed the starting position!

    We have a Ruy Lopez. Nice, looks like they actually looked it up.

    Talk about having a chess-themed episode, then completing fucking up every opening position smh

    Can’t they just open lichess.org or chess.com or Wikipedia or Google Images and just look at it while drawing?

    2024-09-16-21:41:43-+0100-0003.jpg

    Or read this fucking book that clearly has the queen on the d file and king on the e file?

    OK this is actually plausible, if white could bait black to take the knight, then a mad queen could have been possible at some point.
