Gallery of all species in a genus
I have a picture of a fern which supposedly belongs to the genus Blechnum. Is there an online gallery of images that includes all Blechnum species? Is there a website that arranges images of plants into genus-based galleries? Surtsicna (talk) 15:32, 9 May 2019 (UTC)
 * I don't know of any galleries off-hand, but there have been multiple attempts to build apps that serve to identify plants based on their leaves. There's a recap here that may point you to a useful tool. More stuff is outlined at Automated species identification. (I understand none of that answers your literal question; I'm assuming that you're asking for a gallery in order to identify the plant in question). Matt Deres (talk) 19:41, 9 May 2019 (UTC)


 * PetScan can be useful here. Use the thumbnails option. Andy Dingley (talk) 21:05, 9 May 2019 (UTC)

Acoustic stringed instrunents
How, exactly, is the energy of the vibrating string transmitted to the body of the instrument? Ie, how does the bridge transmit the string vibrations to the body? There is no info I can find on this in wikipedia, and very very little else where on the web. 86.8.200.249 (talk) 22:42, 9 May 2019 (UTC)


 * Reflectance and Transmittance of a Yielding String Termination, which is a subchapter of the book we were discussing earlier.
