Gravity Assist: the Planetary Slingshot
How does a gravity assist, or slingshot, work exactly for a spacecraft skimming around a planet? Where does the momentum gain come from?

Why is glass transparent?
If all things consist of molecules, why is it that some materials are transparent while others aren’t? Why is glass transparent?
Spaces and dimensions
What do mathematicians and physicists mean with phrases like higher and/or extra dimensions? Let’s travel through a Universe of spaces and dimensions!
Quantum mechanics in ten ideas for people on the move
If you’re on the move, you don’t have much time. Here are ten important ideas from quantum mechanics you can catch up on. Particles and wave functions!
Complex numbers: an introduction
We will leave the domain of real numbers behind us and start exploring the plane of complex numbers. An introduction to a realm beyond imagination.
Heisenberg’s uncertainty principle
Heisenberg’s uncertainty principle is famous in quantum mechanics. However, it doesn’t have its roots in quantum mechanics. Let’s look at Fourier transform pairs.
Quantum entanglement: the EPR paradox and Bell’s Theorem
Einstein didn’t like that quantum entanglement seemed to imply information travelling faster than the speed of light. We discuss Bell’s Theorem.
Quantum entanglement: non-locality and the state of a two-particle system
In this two-parter, we discuss quantum entanglement, non-locality, and some mathematics. In the next post, we discuss the EPR paradox and Bell’s Theorem.
Lab centrifuges and prime numbers
Lab centrifuges are crucial in e.g. coronavirus research. It’s vital the test tubes are balanced. There is an easy method to know if that’s possible.
The double-slit experiment
We describe the famous double-slit experiment, which proved to be fundamental to our current understanding of quantum physics.
The Collatz Conjecture
The Collatz Conjecture is probably one of the easiest to understand problems which hasn’t yet been answered in the history of mathematics.
This is not an atom
The standard cartoon of an atom is incorrect. An atom is not like a tiny planetary system. Quantum mechanics is all about the wave function. Let’s observe this carefully.
Proof that the square root of 2 is irrational
We will provide the proof that the square root of 2 is irrational through a proof of contradiction. We will show no valid ratio of integers exists.
The meaning of E=mc²
The most famous equation may not be what you think it is. For example, it’s not about converting mass into energy. And, it’s only a part of the whole thing.
Einstein’s special relativity in under 6.999 minutes for people on the move
Especially for people on the move, we discuss as briefly as possible the intricacies of Einstein’s special relativity.
