You might not know that you use quantum technologies every day pretty much constantly. Here I have summarised five of them, but there are many others. Quantum physics is often seen as a weird part of physics, far removed from our every day lives but this couldn’t be further from the truth. The entire modern world exists because of our understanding of quantum physics! #quantum #technology #DomainOfScience You can get this as a poster here: https://www.redbubble.com/people/dominicwalliman/works/27438063-5-ways-you-use-quantum-technology-every-day?asc=u&p=poster&rel=carousel And all my other posters here: https://www.redbubble.com/people/dominicwalliman And free versions for teachers here: https://www.flickr.com/photos/95869671@N08/ And the new Professor Astro Cat App: https://itunes.apple.com/us/app/galactic-genius-with-astro-cat/id1212841840?mt=8 And check out the other professor astro cat things, these links are to the publisher, but they are available in all good bookshops around the world in 18 languages and counting: Frontiers of Space (age 7+): http://nobrow.net/shop/professor-astro-cats-frontiers-of-space/ Atomic Adventure (age 7+): http://nobrow.net/shop/professor-astro-cats-atomic-adventure/ Intergalactic Activity Book (age 7+): http://nobrow.net/shop/professor-astro-cats-intergalactic-activity-book/ Solar System Book (age 3+, available in UK now, and rest of world in spring 2018): http://nobrow.net/shop/professor-astro-cats-solar-system/ Solar System App: http://www.minilabstudios.com/apps/professor-astro-cats-solar-system/ Thanks so much to my supporters on Patreon.
