Geothermal energy is everywhere, just right under our feet. So could it be the solution to climate change? I used to think it was just too difficult and expensive to make much sense in most places, but some recent advances have made me rethink. Let’s have a look. 

Don't Underestimate Geothermal Energy

When Roger Penrose originally came out with the idea that the human brain uses quantum effects in microtubules and that was the origin of consciousness, many thought the idea was a little crazy. According to a new study, it turns out that Penrose was actually right… about the microtubules anyways. Let’s have a look.

Particle physics have conducted a test using data from the Large Hadron Collider at CERN to see if the particles in their collisions play by the rules of quantum physics - whether they have quantum entanglement. Why was this test conducted when previous tests already found that entanglement is real? Is it just nonsense or is it not nonsense? Let’s have a look.

We see constant progress in the world every day, from better cars to faster phones to virtual reality and the internet of things. However, despite all the technological and engineering advances, science seems to be slowing down? Let’s have a look. 

Scientific Progress is Slowing Down. But Why?

Scientists finally succeeded in exiting an atomic resonance with a laser in the near ultraviolet. It's a remarkable feat that they've been working on since the 1970s. It could usher in the era of nuclear precision. Let’s have a look.

It's not a joke, they did indeed name an asteroid after me! I want to use this opportunity as an excuse to explain why asteroids are cool.

Hi All! I have had continued difficulties with my time management and have decided to reduce the number of weekly videos to 5. That said, I am still trying to find a good use for the shorts format, and will be putting in a few of those in the next weeks. Today I have a little maths puzzle.

If nothing gets out of a black hole, how does gravity do it? Something with virtual gravitons? Is this really necessary? It's tricky question, but this is what I can say without resorting to equations. 

How does gravity escape a black hole?

The flat earther community seems to be growing, and it's beginning to worry me. It's not just a question of lacking science education, there is more going on here.
