The Hasse–Weil zeta function is a mathematical tool used in number theory and algebraic geometry, particularly in the study of algebraic varieties over finite fields and their properties. It generalizes the classical Riemann zeta function and serves as an important object in understanding the distribution of points on algebraic varieties defined over finite fields.
The H-derivative, or the Hadamard derivative, is a type of derivative used in the context of functions of one or more variables. It is defined to generalize the ordinary derivative and is particularly useful in certain areas of analysis, such as fractional calculus and mathematical physics.
Heat capacity is a property that indicates the amount of heat energy required to change the temperature of a substance by a certain amount. For elements, heat capacity can be expressed in different forms, commonly as molar heat capacity (the heat capacity per mole of an element) and specific heat capacity (the heat capacity per unit mass).
The Higgs mechanism is a process in particle physics that explains how certain fundamental particles acquire mass through their interaction with the Higgs field. The Higgs field is a scalar field that permeates all of space, and it is associated with the Higgs boson, a fundamental particle confirmed by experiments at the Large Hadron Collider in 2012.
A hectad is a unit of area equal to 100 hectares or 1 square kilometer (km²). It is often used in ecological and environmental studies to describe areas of land, particularly in the context of biodiversity, land use, and conservation. The term is less commonly used than hectares or square kilometers but can be useful for representing relatively small to medium-sized areas in studies that require a specific focus on land management or ecological assessments.
Helene Stähelin is a Swiss botanist renowned for her research in plant physiology and biochemistry. She has made significant contributions to the study of plant signals and responses to environmental stresses.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
