About Hannah Joshua
Hannah is a former physicist and recovering science journalist. Her quirky column for New Scientist magazine focused on building whimsical and delightfully overcomplicated solutions to readers' problems - including a pair of shoes that call you an Uber when you click your heels together, an Alex-powered pedal bin, an autonomous biscuit carrying robot and more. She has since moved on to making even bigger and better things as a special effects technician and content creator.
