We are familiar with degrees as units of angle. But what about more natural units like radians? This shows what rads are.

Cell renewal rates in different tissues of the human body. Giving context through daily life replacement processes, we note that hair elongates at about 1 cm per month while fingernails grow at about 0.3 cm per month, which is about the same speed as the continental spreading in plate tectonics that increases the distance between North America and Europe.

Buddhism entered Han China via the Silk Road, beginning in the 1st or 2nd century CE.

In dynamical systems, a Hopf bifurcation is one where a parameter is varied past a critical point past which a periodic solution emerges. In this example when the weight is closer to the car a limit cycle exists in the dynamics where the system exhibits decaying oscillations, the system is stable. But after the weight is shifted the limit cycle disappears and the system becomes unstable by growing oscillations.

Map of the Conquests of Alexander the Great (356-323 BC) . During his youth, Alexander was tutored by Aristotle until age 16. Alexander broke the power of Persia in a series of decisive battles, most notably the battles of Issus and Gaugamela. He died in Babylon.

The data is taken from a 2014 SRS (Sample Registration System) survey.

The voltage of transmission lines can go anywhere from 69 kV up to 765 kV. The power poles are higher and cables are thicker than ditribution lines. Transmission lines are bi-directional. The voltage of distribution lines varies between 4KV and 69KV.

The angle sum of a triangle being 180° is equivalent to the parallel postulate.

Roll a circle inside a circle three times as big. You get a curve with three sharp corners called a “deltoid,” shown in red above. It’s not obvious that you can describe this using a polynomial equation, but you can. The great mathematician Leonhard Euler dreamt this up in 1745. Credits : Sam Derbyshire

At -250 C you can make Niobium–tin superconducting. Around -265 C for lead and mercury. Now you can have highly pressurized (150 gigapascals) lanthanum decahydride (LaH10) transitioning at −23 °C. Note in conducting metals the interaction between conducting electrons and phonons (crystalline lattice) is poor. While superconductivity needs that interaction.

The study of turbulence allowed us to make balls that travel longer distances. Golf ball dents explained
