How Microwaving Grapes Makes Plasma

From 1veritasium, 2veritasium, or sciencium. A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other creating a maximum of electromagnetic energy where they…

Could Netflix Fix Science?

From 1veritasium, 2veritasium, or sciencium. Researchers spend much of their time writing grant applications, which adds up to a lot of wasted resources. Is there a better way to fund science? Special thanks to Profs. Kevin Gross and Carl T. Bergstrom. Their paper “Contest models highlight inherent inefficiencies of scientific funding competitions” https://arxiv.org/abs/1804.03732

A Billion Years of Moon Impacts Illuminates Earth’s History

From 1veritasium, 2veritasium, or sciencium. A study just published reveals the moon experienced a dramatic increase in cratering rates about 300 million years ago. This corroborates evidence of a similar increase in Earth impacts. The paper is: The Earth and Moon impact flux increased at the end of the Paleozoic Sara Mazrouei, Rebecca R. Ghent,…

Spinning Black Holes

From 1veritasium, 2veritasium, or sciencium. A pulsing black hole in the centre of a distant galaxy sheds light on black hole and galaxy formation. How fast are black holes rotating and how does that rotation change over its life-span? Huge thanks to Prof. Geraint Lewis and study author Dr. Dheeraj Pasham. A loud quasi-periodic oscillation…

Anti Social Media

From 1veritasium, 2veritasium, or sciencium. The main reason I don’t like social media. What do you think? Do you agree with me or not? I noticed a few years ago that on Facebook I was doing complicated calculations like: Do I actually like this post? Yes/No Do I want the person to know I like…

Five Firsts for Mars InSight

From 1veritasium, 2veritasium, or sciencium. Mars InSight will be the first to detect seismic activity on Mars’ surface, first to measure rate of heat transmitted from interior, first to dig nearly 5m down, first to measure magnetic fields on Mars’ surface, and first to use a robotic arm to place instruments on the surface of…

ZERO-G Challenges of a Trip to Mars!

From 1veritasium, 2veritasium, or sciencium. A trip to #Mars involves radiation, muscle and bone loss, intermediate axis theorem and liquids. Check out Mars on National Geographic, Monday Nov 12 at 9/8c #sponsored When I got offered the chance to fly in another #zeroG plane, I jumped at the chance. Do you know how hard it…

The Scientific Benefits of Boredom

From 1veritasium, 2veritasium, or sciencium. Boredom makes you more creative, altruistic, introspective, and helps with autobiographical planning. This video was sponsored by LastPass: http://bit.ly/2wAsdUu I feel like this video might come across as condescending but the person I’m really talking to is myself.
