Two equations are enough to go to the Moon
All the physics you need to go to the Moon is taught in schools. And was published by some dude whose birthday is coming up. Continue reading Two equations are enough to go to the Moon
Theoretical donuts and quantum computers: the Nobel prize 2016
So it wasn’t gravitational waves after all: the Nobel prize for physics went to David Thouless, Duncan Haldane and Michael Kosterlitz. That’s the easy part. The motivation needs a little unpacking: For theoretical discoveries of topological phase transitions and topological phases of matter. We all know and love a few phases of matter: solid, liquid and gas (maybe plasma if you want to get kinky). … Continue reading Theoretical donuts and quantum computers: the Nobel prize 2016
How many times can you fold a piece of paper?
Some time ago I came across a fun article. I got curious, and embarked on a journey that took me to the source of a famous internet myth and even to explore what it means to be a physicist. But let’s not get ahead of ourselves. The article was about the myth that it’s impossible to fold a piece of paper more than 7 times, … Continue reading How many times can you fold a piece of paper?
Aristotle is always wrong, but that’s alright
The Sun, the planets and the whole universe revolve around the Earth while hanging on crystal spheres. The velocity of a body is proportional to the force that pushed it. A rock falls to the ground because that’s its natural element. Those are only a few of the teachings of Aristotle that, forced on posterity for centuries, held back scientific progress. Whatever your branch of … Continue reading Aristotle is always wrong, but that’s alright
Speed limits
Light travels at about 299792458 meters per second. Why not more? or less? Why can’t it have more than one speed? To tell the truth, light does have more than one speed: the one we know, the one that nothing can surpass, is the speed of light in a vacuum. But if it goes through a material, light travels slower. More than that, light of … Continue reading Speed limits
