MOUNTAIN Olympus Mons on Mars, the largest mountain in our solar system, owes its colossal height to Mars' weaker gravity, a result of its lower mass compared to Earth. This reduced gravitational pull means that the downward gravitational force or weight opposing the buoyancy of rising magma is smaller, allowing the mountain to grow taller than Earth’s highest peaks, like Mount Everest. ...However, buoyancy itself is also affected by gravitational force. With less gravity, the buoyant force decreases, but it still faces less resistance when pushing magma upward. In other words, despite the lower buoyant force due to weaker gravity, the overall resistance to the magma is minimized. This intricate balance of forces on Mars enables the formation of such towering volcanic giants.

The solid and broken bars in the eight image tiles in the top navigation are called trigrams. The octagonal trigram pattern is a common symbol for the Chinese term Bagua. The pattern has eight (ba) areas (guas). "South" is always found at the top of the Bagua. Each trigram represents a particular natural phenomena: Sky ☰, Lake ☱, Fire ☲, Thunder ☳, Wind ☴, Water ☵, Mountain ☶, Earth ☷. If you click on a trigram, it will take you to the corresponding taekwondo form page. Each form has a trigram which I describe scientifically and call scigrams. The tangram animation in the middle of the trigram tiles is supposed to represent a kicking woman. A tangram is a puzzle which originated in China. It is created out of seven flat polygons that can be put together to form shapes.


The movements are listed here so that you can see the Korean translation for some of the techniques by hovering over the green and pink highlighted text.
