How to Move the Sun: Stellar Engines

January 7th, 2020|

Nothing in the Universe is static. In the milky way, billions of stars orbit the galactic center. Some, like our sun, are pretty consistent, keeping a distance of around 30,000 light years from the galactic center, completing an orbit every 230 million years. This dance is not an orderly ballet - more like a [...]

What are Gravitational Waves?

December 5th, 2019|

What are gravitational waves? In September 2015, scientists witnessed something never seen before: two black holes colliding. Both about 30 times as big as our Sun, they had been orbiting each other for millions of years. A fraction of a second before the crash, they sent a vibration across the universe at the speed [...]

The Physics of Drifting, Explained

July 12th, 2019|

Here's an in-depth look at the physics of drifting from Business Insider: Car drifting is both a pastime and profession. For hobbyists and professionals, the basic principles of drifting are the same. Toss the car sideways and hang on. We wanted to take a deeper look into the activity. We asked Leona Chin, a professional [...]

What is Entropy?

January 23rd, 2019|

There’s a concept that’s crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It’s entropy, and it’s notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course [...]

Why don’t perpetual motion machines ever work?

December 18th, 2018|

Perpetual motion machines could totally transform our relationship with energy ... if only they worked. Ideas for perpetual machines all violate one or more laws of thermodynamics.

The Standard Model of Particle Physics

November 19th, 2018|

Matter is made of fundamental particles and these particles interact with each other according to a theory called the Standard Model. Watch this video from Ted-Ed to know more.

Does time exist?

We actually don't know if time exists. This video from Ted shows why time puzzles scientists:

Faith in Physics

August 27th, 2018|

In this episode of the ABC’s classic science program, ‘Why Is It So?’, Professor Julius Sumner Miller re-attempts a favourite experiment, and things don’t quite go to plan. That's why we should all have faith in Physics.
