Science Vs. Cinema: The Martian
How accurate is the science in Ridley Scott’s latest film “The Martian“? Many science fiction films tend to be just that: fiction. Some of them are more fantastical than others, and some are much more grounded in reality. Where does The … Continue reading
Definitions Of Fact, Theory, And Law In Scientific Work
Over at the National Centre for Science Education, they have a handy little explainer of what a Fact, Theory, Hypothesis, and Law is in scientific work. These terms are often misunderstood by people who don’t work in the field, so it’s … Continue reading
What Physics Teachers Get Wrong About Tides
“Everything you’ve learned about tides is WRONG. We know that gravity affects the motion of all objects equally – so why are oceans the only bodies of water with tides? Join Gabe on this week’s episode of PBS Space Time … Continue reading
Robots Falling Down At The DARPA Robotics Challenge
This compilation of robots falling down is far funnier than it should be. I love how they start falling down in almost slow motion, an inevitability of gravity pulling down on them as soon as they go slightly off balance. … Continue reading
Throwback Thursday #19
Throwback Thursday is here once again. To start this week off, we have a mix of the Cornetto trilogy films by Edgar Wright, and it’s rather well done. If you haven’t seen any / all of those films, you’re missing out, … Continue reading
How Do Airplanes Fly?
Simple explanation of how airplanes fly, by MinutePhysics. All to do with force and pressure. Lift, gravity, thrust, and drag all play a role in keeping airplanes flying, and when they balance each other out, this results in no net force. … Continue reading
Rotating Rooms & Zero Gravity
“The zero-gravity hallway fight scenes were achieved by using “…massive, rotating sets that twisted and turned and forced Gordon-Levitt to manoeuvre with utmost caution. Five-hundred crew members were involved in the scene, which took a full three weeks to complete.” The sets were … Continue reading
OK Go – Red Star Macalline Commercial
A fantastic commercial OK Go did for the Chinese furniture store Red Star Macalline. It’s a combination of the visuals of their music video for “The Writing’s On The Wall” coupled with a remix of their song “I Won’t Let You … Continue reading
Why Science Is NOT ‘Just A Theory’
“Have you ever heard ‘evolution’ dismissed as ‘just a theory’? Is a scientific theory no different to the theory that Elvis is still alive? Jim Al-Khalili puts the record straight. There’s an important difference between a scientific theory and the … Continue reading
The Potsdam Gravity Potato
“Why do some places on Earth have higher gravity than others? Sometimes the reason is unknown. To help better understand the Earth’s surface, sensitive measurments by the orbiting satellites GRACE and CHAMP were used to create a map of Earth’s … Continue reading
