I am Googling "conoid" right now and I still can't even imagine what it's supposed to be.
The Google dictionary says it's a zoological term "approximately conical in shape".
The Wikipedia panel says "In geometry a conoid is a ruled surface, whose rulings fulfill the additional conditions: All rulings are parallel to a plane, the directrix plane. All rulings intersect a fixed line, the axis." The graphics are... nothing intuitive.
The M-W link in the search results says "a cone-shaped structure; especially : a hollow organelle shaped like a truncated cone that occurs at the anterior end of the organism".
None of this seeming relevant, I clicked on the Image tab and it's all these complicated Mathematica-style graphs of things that are very much not cones.
I see other people in the HN comments similarly have no idea.
Can you please explain what you saw on screen? What did the captcha think was a conoid...? Like, traffic cones or something?
- ayewo 2y agoUsing the touch pad to long-press on the text "conoid" in my browser brought up the built-in dictionary definition on macOS: > conoid | ˈkəʊnɔɪd | mainly Zoology adjective (also conoidal | kəʊˈnɔɪd(ə)l | ) approximately conical in shape. > noun a conoid object: her hull was a conoid, tapering towards the bow.
- recursive 2y agoYeah, that's the zoological definition again.
- genewitch 2y agoIn the UK some crosswalks have cones on the bottom of the box where the button to wait to cross is, and OP mentioned crosswalks in the final sentence. Maybe it's just too late for me right now, but that's what my brain assumed, but the "same number of shapes as" thing was not enough context! the cone on the bottom spins when you have the right of way.
