In 1976, NASA’s Viking mission successfully landed the first spacecraft on Mars. When the mission began sending images from Mars’ surface back to Earth, scientists noted long, dark streaks on crater walls and cliff sides. To this day, some researchers suggest that the strange geographical features are the result of water flow—but a recent study says otherwise. Planetary scientists from Brown University and the University of Bern have used artificial intelligence to reveal that the enigmatic Mar

Learning, to a computer, is just turning bad guesses into better ones. In this post, we’ll see how that starts with a straight line: how linear regression makes the first guess, and gradient descent keeps improving it. Let's start with something familiar: house prices. Bigger houses tend to cost more; smaller ones, less. It's the kind of pattern you can almost see without thinking: more space, more money. When we plot it, the shape is clear: a loose upward slope, with some noise but a definite

For the full article covering many properties of e , including history and comparison with existing methods of teaching: PDF from arXiv. A video explanation will be posted here shortly. This webpage pulls out the part of the article which uses Pre-Calculus language to explain what is so natural about e , while intuitively connecting the following two important properties: The slope of the tangent line to y = e x at the point ( x , e x ) is just e x . (In Calculus language: e x is its own deriv
