    Turbulence: One of The Great Unsolved Mysteries of Physics

    Turbulence: One of The Great Unsolved Mysteries of Physics

    You're on an airplane when you feel a sudden jolt. Outside your window nothing seems to be happening, yet the plane continues to rattle you and your fellow passengers as it passes through turbulent air in the atmosphere. What exactly is turbulence, and why does it happen? Tomás Chor dives into one of the prevailing mysteries of physics: the complex phenomenon of turbulence.

    Ultrasound: Application in Food Science and Technology 超聲波於食品科技中的應用

    Ultrasound: Application in Food Science and Technology 超聲波於食品科技中的應用

    An online lecture on the topic of "Ultrasound: Application in Food Science and Technology". The Faculty of Applied Science and Textiles (FAST) and the Institute of Textiles & Clothing (ITC) organized the mini-lecture series for more than three years. The lectures aim to enrich students' knowledge in creative perspectives and arouse their interest in Sciences, Fashion and Textiles. In view of the unpredictable development of the COVID-19 pandemic, the upcoming mini-lecture Series will be switched from face-to-face mode to online mode.

    Want To Grow Healthy Food? Start with Your Lawn

    Want To Grow Healthy Food? Start with Your Lawn

    The fruits and vegetables we buy from the grocery story have been bred to grow bigger and faster — but at the cost of flavor and nutrition, says John C. Trimble, co-founder of Foodscaping Utah. Instead of wasting precious water to maintain the grass in our yards, he suggests we "foodscape" them instead. Not only will our produce taste better, but they'll be grown as locally as possible.

    What Happens When Biology Becomes Technology?

    What Happens When Biology Becomes Technology?

    "We've been promised a future of chrome -- but what if the future is fleshy?" asks biological designer Christina Agapakis. In this awe-inspiring talk, Agapakis details her work in synthetic biology -- a multidisciplinary area of research that pokes holes in the line between what's natural and artificial -- and shares how breaking down the boundaries between science, society, nature and technology can lead us to imagine different possible futures.

    What Physics Taught Me about Marketing

    What Physics Taught Me about Marketing

    Physics and marketing don't seem to have much in common, but Dan Cobley is passionate about both. He brings these unlikely bedfellows together using Newton's second law, Heisenberg's uncertainty principle, the scientific method and the second law of thermodynamics to explain the fundamental theories of branding.
