This is the World's Loneliest Tree (02:53)

Great Big Story · 1 year ago
Tucked away in a corner of London's Royal Botanic Gardens, there is a very peculiar plant. At first glance, it resembles a stumpy palm tree, but this ancient specimen is incredibly rare. It is, in fact, the very last of its kind on Earth. Encephalartos woodii is a cycad, a type of plant that once dominated the planet during the Jurassic Period. Over the millennia, the age of the cycad came to an end. And in the case of Encephalartos Woodii, we may have been left with only one—a single male specimen. This tree is the loneliest bachelor on Earth.

RetroTech: Recordable Paper - The 3M Sound Page (12:23)

Techmoan · 1 week ago
In this video I take a look at a multimedia educational format from the 1970s, the 3M Sound Page (AKA Ricoh Synchrofax) UPDATE I’ve seen a few comments where the assumption has been made that this device was still in use as an educational tool in the 1990s. I think this is highly unlikely. Here’s my take on this - if you’ve ever gone to school, you’ll know that they rarely throw anything away. I know in my school there were things in storage cupboards that hadn’t been used in decades. My theory is that this was used in the 1970s and then stored away until being discovered in the 1990s by some mischievous children who liberated it and used it to record music off the radio (over the top of the old teachers programmes). COMPLAINTS RECEIVED (SO FAR) 1) The use of the term ‘ASMR Nuts’ The definition of Nut as used in this context is as follows: A person who is enthusiastic about a specific thing; e.g. Car nut Football Nut Health Nut I am a Technology Nut - and I’m proud of it. So you’ll have to find something else to pretend to get outraged by today. 2) ‘Fat Shaming’ 3) ‘Flat Earth” The recordings used in this video are taken from educational programmes made in 1974. Your 2018 complaints or observations on something from 44 years ago will need to be addressed to the creator of those programmes. ---------------SUBSCRIBE------------------ http://www.youtube.com/user/Techmoan?sub_confirmation 1 -------------Merchandise----------------- https://teespring.com/stores/techmoan-merch -------------SUPPORT--------------- This channel can be supported through Patreon https://www.patreon.com/techmoan Patrons usually have early access to videos -------THANKS TO ------- Jerobeam Fenderson for the intro animation: http://oscilloscopemusic.com/ Muppet Teletext Graphic - courtesy of @ZXGuesser (on Twitter) Also available here: https://zxnet.co.uk/teletext/gallery/index.php?gallery gallery3 ----------Outro Music----------- Over Time - Vibe Tracks https://youtu.be/VSSswVZSgJw ------Outro Sound Effect------ ThatSFXGuy - https://youtu.be/5M3-ZV5-QDM
